Loans which have been originated by Westpac Banking Corporation (ARBN 007 457
141) ("Westpac") in the ordinary course of its business. The Housing Loans will
be sold either by Westpac or the Seller Trustee (as defined herein) to the
Issuer Trustee. The Offered Notes and the Transaction Documents (other than the
Security Trust Deed and certain of the Swap Agreements) are governed by, and
shall be construed in accordance with, the laws of New South Wales, Australia.
The Security Trust Deed (as defined herein) is governed by, and shall be
construed in accordance with, the laws of the Australian Capital Territory.
 
    The Issuer Trustee was incorporated on 11th July 1944 as, and continues to
exist and operate as, a limited liability public company under the Corporations
Law of New South Wales, Australia. The Trust will be formed on or about

    The Offered Notes shall be subject to mandatory redemption in part on any
Payment Date if on that date there are any Principal Collections (as defined
herein) available to be distributed in relation to the Offered Notes. The
Offered Notes are also subject to optional redemption in full in certain
circumstances described herein.
 
    The Class A Notes rank PARI PASSU and without any preference among
themselves and the Class B Notes rank PARI PASSU and without any preference
among themselves. The right to payment of principal of and interest on the Class
B Notes is subordinated and may be limited as more particularly described
herein. In addition, under certain limited circumstances, the Trust may issue
certain additional debt securities, the Redraw Funding Securities ("RFSs"),
which in certain circumstances will convert to RFS Class A Notes (the "RFS Class
A Notes"). Upon conversion, the RFS Class A Notes will rank PARI PASSU in
respect of priority of principal and interest with the Class A Notes. The RFSs,
along with repayments under the Redraw Facility (as defined herein), will be
senior in priority of distributions of principal to the Class A Notes and the
RFS Class A Notes. The RFSs, the RFS Class A Notes and fees with respect to the
Redraw Facility and the Class A Notes will rank PARI PASSU in respect to
priority of payments of interest. Payments in respect of principal and interest
in respect of the Class B Notes are subordinated to such payments in respect of
the Class A Notes, RFSs and RFS Class A Notes. See "DESCRIPTION OF THE OFFERED
NOTES--Description of the Redraw Facility, the Redraw Funding Securities and the
RFS Class A Notes," "--Interest Payable on the RFSs and the RFS Class A Notes"
and "--Subordination of the Class B Notes; Priority of Payment of Principal to
RFSs." The RFSs and the RFS Class A Notes are not being offered hereby.
 
    The Offered Notes may not, in connection with their initial distribution, be
offered or sold, directly or indirectly, in the Commonwealth of Australia, its
territories or possessions or to any resident of Australia.
 
    The Offered Notes should not be acquired by any associate (as defined in
Section 128F of the Income Tax Assessment Act of 1936 of Australia) of the
Issuer Trustee (which for these purposes, is Westpac and its associates).
 
    The Issuer Trustee's liability to make payments in respect of the Offered
Notes is limited to its right of indemnity from the assets of the Trust which
are from time to time available for this purpose pursuant to the Master Trust
Deed, the Series Notice and the Security Trust Deed. All claims against the
Issuer Trustee

                                  ANNOUNCEMENT
 
   
    By distributing or arranging for the distribution of this Prospectus to the
Underwriters and the persons to whom this Prospectus is distributed, the Issuer
Trustee announces to the Underwriters and each such person that: (1) the Offered
Notes will be issued in the form of one or more Book-Entry Notes issued to and
lodged with Cede & Co. as nominee of DTC; (2) in connection with the issue, DTC
will confer rights in relation to the Offered Notes and Noteholders and will
record the existence of those rights; and (3) as a result of the issue of the
Offered Notes in this manner, such rights will be able to be created.
    
 
                             REPORTS TO NOTEHOLDERS
 
    Unless and until Definitive Notes (as defined herein) are issued, quarterly
and annual unaudited reports containing information concerning the Trust and the
Offered Notes will be prepared by the Trust Manager and sent on behalf of the
Issuer Trustee to Cede & Co. ("Cede"), as nominee of DTC as registered holder of
the Offered Notes pursuant to the Note Trust Deed. See "DESCRIPTION OF THE
OFFERED NOTES--Book-Entry Registration" and "--Determination Date- Calculations
and Reports to Noteholders." Such reports will be made available by the Issuer
Trustee to DTC and its participants. DTC and its participants will make such
reports available to holders of interests in the Offered Notes in accordance
with the rules, regulations and procedures creating and affecting DTC. However,
such reports will not be sent directly to each beneficial owner while the
Offered Notes are in book-entry form. Upon the issuance of fully registered,
certificated Offered Notes, such reports will be sent directly to each
Noteholder. Such reports will not constitute financial statements prepared in
accordance with generally accepted accounting principles. The Trust Manager, on
behalf of the Issuer Trustee, will file with the Securities and Exchange
Commission (the "Commission") such periodic reports as are required under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules
and regulations of the Commission thereunder. However, in accordance with the
Exchange Act and the rules and regulations of the Commission thereunder, the
Trust Manager expects that the Issuer Trustee's obligation to file such reports
will be terminated following the end of June 1999.

offered or sold, directly or indirectly, and neither this Prospectus nor any
offering circular, prospectus, form of application, advertisment or other

applicable laws and regulations and the Underwriters have represented that all
offers and sales by them have been and will be made on such terms. Persons into

Trustee or any of the Underwriters. Neither the delivery of this Prospectus nor
any sale made in connection herewith shall, under any circumstances, create any
implication that there has been no material change in the affairs of the Issuer
Trustee or any other party named in the Prospectus since the date hereof or the
date upon which this document has been most recently amended or supplemented or
that there has been no material adverse change in the financial position of the

should make its own independent investigation of the financial condition and
affairs, and its own appraisal of the creditworthiness of the Issuer Trustee and
each investor should seek its own tax, accounting and legal advice as to the
consequences of investing in any of the Offered Notes and none of the Servicer,
Trust Manager, the Seller Trustee, Westpac, the Note Trustee, the Security
Trustee, any Mortgage Insurer or any of the Underwriters accept any
responsibility or make any representation as to the tax consequences of
investing in the Offered Notes.

                 ENFORCEMENT OF FOREIGN JUDGMENTS IN AUSTRALIA
 
    The Trust Manager is an Australian proprietary company incorporated with
limited liability under the Corporations Law. Any final and conclusive judgment
of any New York State or United States Federal Court sitting in the Borough of
Manhattan in the City of New York having jurisdiction recognized by the relevant
Australian jurisdiction in respect of an obligation of the Trust Manager in
respect of an Offered Note, which is for a fixed sum of money and which has not
been stayed or satisfied in full, would be enforceable by action against the
Trust Manager in the courts of the relevant Australian jurisdiction without a
re-examination of the merits of the issues determined by the proceedings in the
New York State or United States Federal Court, as applicable, unless: (a) the
proceedings in New York State or United States Federal Court, as applicable,
involved a denial of the principles of natural justice; (b) the judgment is
contrary to the public policy of the relevant Australian jurisdiction; (c) the
judgment was obtained by fraud or duress or was based on a clear mistake of
fact; (d) the judgment is a penal or revenue judgment; or (e) there has been a
prior judgment in another court between the same parties concerning the same
issues as are dealt with in the judgment of the New York State or United States
Federal Court, as applicable. A judgment by a court may be given in some cases
only in Australian dollars. The Trust Manager expressly submits to the
jurisdiction of New York State and United States Federal Courts sitting in the
Borough of Manhattan in the City of New York for the purpose of any suit, action
or proceedings arising out of this offering. The Trust Manager has appointed
Lewis E. Love, Jr., its Director and Secretary, 575 Fifth Avenue, 39th Floor,
New York, New York 10017-2422, as its agent upon whom process may be served in
any such action.
 
    The majority of the directors and executive officers of the Trust Manager,
and certain experts named herein, reside outside the United States (in the
Commonwealth of Australia). Substantially all or a substantial portion of the
assets of all or many of such persons are located outside the United States. As
a result, it may not be possible for holders of the Offered Notes to effect
service of process within the United States upon such persons or to enforce
against them judgments obtained in United States courts predicated upon the
civil liability provisions of Federal securities laws of the United States. The
Trust Manager has been advised by its Australian counsel Allen Allen & Hemsley,
that, based on the restrictions referred to above, there is doubt as to the
enforceability in the Commonwealth of Australia, in original actions or in
actions for enforcement of judgments of United States courts, of civil
liabilities predicated upon the Federal securities laws of the United States.
 
                       EXCHANGE CONTROLS AND LIMITATIONS
 
    Under temporary Australian foreign exchange controls, payments by an
Australian resident to, or on behalf of: (a) the Government of Iraq or its
agencies or nationals; (b) the authorities of the Federal Republic of Yugoslavia
(Serbia and Montenegro); or (c) the Government of Libya or any public authority
or controlled entity of the Government of Libya may only be made with Reserve
Bank of Australia approval. Such restrictions may change in the future. See
"RISK FACTORS--Risks of Currency Exchange Controls."
 
                            U.S. DOLLAR PRESENTATION
 
   
    In this Prospectus, references to "U.S. dollars" and "US$" are references to
U.S. currency and references to "Australian dollars" and "A$" are references to
Australian currency. Unless otherwise stated herein, the translations of
Australian dollars into U.S. dollars have been made at a rate of
US$.6260=A$1.00, the noon buying rate in New York City for cable transfers in
Australian dollars as certified for customs purposes by the Federal Reserve Bank
of New York on May 29, 1998. Use of such rate is not a representation that
Australian dollar amounts actually represent such U.S. dollar amounts or could
be converted into U.S. dollars at that rate.

                                  referred to herein as the "Paying Agents".
Roles of the Security Trustee
  and Note Trustee..............  The structure of the Series 1998-1G WST Trust transaction
                                  employs several different trustees. The Security Trustee
                                  is the entity that holds a security interest over the
                                  Trust Assets (as defined herein) and has the
                                  responsibility of securing such assets and distributing
                                  the proceeds received upon the liquidation of such assets
                                  upon the occurrence of a default and enforcement of the
                                  security interest. The Note Trustee is the entity which
                                  represents the interests of the Offered Noteholders. The
                                  provisions of the Security Trust Deed require the Security
                                  Trustee to consult with, and obtain the consent of, the
                                  Note Trustee before taking certain actions. Thus, not only
                                  does the Security Trustee owe fiduciary duties to the Note
                                  Trustee (and the Offered Noteholders and the other secured
                                  creditors), it has contractual obligations to consult with
                                  and act at the Note Trustee's direction in accordance with
                                  the Security Trust Deed. The Note Trustee owes fiduciary

                                  Collections.
                                  On or before the Closing Date, Westpac as provider of the
                                  Redraw Facility (as defined herein) will enter into a
                                  Redraw Facility Agreement (as defined herein). If Gross

                                  fund a redraw provided to a Borrower by Westpac, drawings
                                  will be made under the Redraw Facility Agreement to fund
                                  the redraw (up to the limit set out in the Redraw Facility

                                  "RFSs". The RFSs and payments under the Redraw Facility
                                  Agreement will be senior in priority of distributions of
                                  principal to the Class A Notes and RFS Class A Notes (as

                                  are held in book-entry form) or the last day of the prior

                                  interest on its Invested Amount. The "Invested Amount" of

                                  shall be an interpolated rate calculated with reference to
                                  the period from (and including) the Closing Date to (but
                                  excluding) the first Payment Date.
                                  With respect to any Payment Date, interest on a Class of
                                  Offered Notes will be calculated as the product of (a) the
                                  Invested Amount of such Class as of the first day of that
                                  Interest Period after giving effect to any payments of
                                  principal to be made thereon; (b) the Interest Rate for
                                  such Class for the related Interest Period; and (c) a
                                  fraction, the numerator of which is the actual number of
                                  days in that Interest Period and the denominator of which
                                  is 360 days (such product with respect to a Payment Date,
                                  "Interest"); provided, however, that once the Stated
                                  Amount of such Class has been reduced to zero, the related
                                  Class will no longer accrue interest because the related
                                  Class will have been redeemed pursuant to the terms of the
                                  Transaction Documents. The "Stated Amount" of a Note is
                                  the Invested Amount of the Note less the Carryover Charge
                                  Offs (as defined herein) applied against it.

                                  payments due to such holders and to provide holders of the

                                  of any unrepaid Principal Draws on such Payment Date. The
                                  application of such amounts, if any, will reduce the
                                  likelihood of the Offered Noteholders receiving less than
                                  their Initial Invested Amount on or prior to the Maturity

Security for the Offered Notes
  General.......................  The Offered Notes are debt obligations of the Issuer
                                  Trustee in its capacity as trustee of the Trust only (and
                                  therefore the Issuer Trustee's liability to make payments
                                  of interest and principal on the Offered Notes is limited
                                  to the collections received by the Issuer Trustee from the
                                  Trust Assets) and except in certain limited circumstances
                                  are not the personal obligation of the Issuer Trustee. See
                                  "THE ISSUER TRUSTEE--Limitation of Issuer Trustee's
                                  Liability." The Offered Notes are issued with the benefit
                                  of, and subject to the terms of, the Transaction
                                  Documents. The Issuer Trustee's liability in respect of
                                  the Offered Notes is limited to the assets of the Trust
                                  available in accordance with the terms of the Transaction
                                  Documents to meet its obligations in relation to the
                                  Offered Notes and, except in certain limited
                                  circumstances, the Issuer Trustee will not be personally
                                  liable in respect of the Offered Notes.
 
  A. The Housing Loans..........  The Housing Loans will consist of 21,132 Housing Loans
                                  with an aggregate Balance Outstanding on the Cut-Off Date
                                  of A$2,252,766,010. The Housing Loans are also referred to
                                  herein as the "Mortgage Pool." The Housing Loans will be
                                  secured by Mortgaged Properties (as defined herein)
                                  located in any of the six states or two territories of
                                  Australia. A "Mortgaged Property" means the land,
                                  including all improvements thereon, that is the subject of
                                  a Mortgage.
 
                                  Generally each Housing Loan is secured by a registered
                                  first ranking mortgage over the related Mortgaged Property
                                  or if the Housing Loan is not secured by a first ranking
                                  mortgage the Approved Seller will assign to the Issuer
                                  Trustee all prior ranking registered mortgages in relation
                                  to that Housing Loan. "Registered" means the mortgage has
                                  been filed with the lands office in the relevant
                                  Australian State or Territory, granting certain rights
                                  with respect to the applicable Mortgaged Property. See
                                  "APPENDIX I--GLOSSARY OF AUSTRALIAN LEGAL TERMS."
 
                                  Each Housing Loan requires that the borrowers on such
                                  Housing Loan (each, a "Borrower") make a minimum payment
                                  (the "Scheduled Payment") on or before the due date for
                                  such Scheduled Payment under the relevant Housing Loan
                                  documents. If Scheduled Payments are not received with
                                  respect to certain Housing Loans on the related due date
                                  either a default rate of interest may be charged on any
                                  overdue amounts or there will be a compounding of
                                  interest.
 
                                  All weighted averages specified herein are weighted based
                                  on the Cut-Off Date Balances Outstanding of the Housing
                                  Loans. With respect to each Housing Loan, the "Cut-Off
                                  Date Balance Outstanding" is the unpaid principal balance
                                  of such Housing Loan as of the close of business on the
                                  Cut-Off Date. All Housing Loan statistics set forth herein
                                  are based on principal balances, interest rates, terms to
                                  maturity, mortgage loan counts and similar statistics as
                                  of the Cut-Off Date, unless indicated to the contrary
                                  herein.

                                  percentages of the Cut-Off Date Balance Outstanding.
 
                                  The Housing Loans bear interest at variable and fixed
                                  rates (the "Mortgage Rates") which, as of the Cut-Off
                                  Date, range from approximately 5.69% per annum to 10.15%
                                  per annum. The weighted average Mortgage Rate of the
                                  Housing Loans on the Cut-Off Date is approximately 6.57%
                                  per annum. The Cut-Off Date Balances Outstanding of the
                                  Housing Loans ranged from approximately A$10,027 to
                                  A$735,606. The average Cut-Off Date Balance Outstanding of
                                  the Housing Loans is approximately A$106,604. The weighted
                                  average original term to stated maturity of the Housing
                                  Loans is approximately 297.11 months. The weighted average
                                  remaining term to stated maturity of the Housing Loans is
                                  approximately 288.41 months. As of the Cut-Off Date, the
                                  weighted average number of months that had elapsed since
                                  origination of the Housing Loans is approximately 8.7
                                  months.
 
                                  Housing Loans representing approximately 18.92% of the
                                  Cut-Off Date Pool Balance are secured by Mortgaged
                                  Properties which are investment properties (based solely
                                  upon statements made by the related Mortgagors at the time
                                  of origination of the related Housing Loans).
 
                                  The lowest and highest LVR as of the Cut-Off Date of the
                                  Housing Loans were approximately 1.99% and 94.96%. LVR is
                                  calculated as a fraction, expressed as a percentage, the
                                  numerator of which is the outstanding amount of the
                                  Housing Loan, plus any other amount serviced on the
                                  Servicing System of the Servicer (the "Mortgage Servicing
                                  System") and secured by the relevant Mortgage Property at
                                  the Cut-Off Date and the denominator of which is the
                                  aggregate value of the Mortgaged Property subject to the
                                  related Mortgage for that Housing Loan. The Mortgaged
                                  Property is generally valued at the time of origination.

                                  Shortfall (a "Principal Draw"). See "DESCRIPTION OF THE
                                  OFFERED NOTES--Principal Draws" below.
 
                                  Amounts paid from any Principal Collections in this way
                                  will be reimbursed through any Excess Available Income to
                                  the extent available in subsequent periods after all
                                  Principal Charge Offs and Carryover Charge Offs (as
                                  defined herein) have been met out of that Excess Available
                                  Income for the relevant period. If there is insufficient

                                  principal repayable on the Notes at maturity may be
                                  reduced by an amount equal to the amount of any such
                                  shortfall.
 
                                  2. LIQUIDITY FACILITY: Under the Liquidity Facility,
                                  Westpac in its capacity as the provider of the Liquidity
                                  Facility (the "Liquidity Facility Provider") agrees to
                                  make advances to the Issuer Trustee for the purpose of
                                  temporarily funding certain income shortfalls in the
                                  Trust, up to an aggregate amount being the lesser of: (1)
                                  A$79,000,000, (2) the Unpaid Balance of all Performing
                                  Loans from time to time, and (3) any lesser amount as is
                                  agreed in writing between the Liquidity Facility Provider,
                                  the Issuer Trustee, the Trust Manager and the Rating
                                  Agencies, as such amount may be reduced or cancelled under
                                  the Liquidity Facility (the "Liquidity Limit"). The
                                  "Unpaid Balance" of a Housing Loan, means the sum of (a)
                                  the unpaid principal amount of that Housing Loan; and (b)
                                  the unpaid amount of all finance charges, interest
                                  payments and other amounts accrued on or payable under or
                                  in connection with that Housing Loan or the related
                                  Mortgage or other rights relating to the Housing Loan.
 
                                  A "Performing Loan" at any date is a Housing Loan which is
                                  not Delinquent or has been Delinquent for less than 90
                                  consecutive days, or if it has been Delinquent for 90 or
                                  more consecutive days, was insured under a Mortgage
                                  Insurance Policy at the date of the Liquidity Facility. A
                                  Housing Loan is "Delinquent" if the related Borrower fails
                                  to pay any amount due on the related due date. Delayed

                                  the Issuer Trustee will grant a first ranking floating
                                  charge over the Trust Assets to the Security Trustee, in
                                  order to secure the Issuer Trustee's obligations to the

                                  the Swap Providers (as defined herein), the Security

                                  Facility (other than the provider of a Mortgage Insurance
                                  Policy), to the Approved Sellers in respect of any Accrued
                                  Interest Adjustment, to Westpac in respect of Redraws, to
                                  the holders of the RFSs (if any) and the holders of the
                                  RFS Class A Notes (if any) (such creditors, together the
                                  "Mortgagees"). A "Support Facility" is any of the
                                  Liquidity Facility, the Redraw Facility, the Swap

                                  The Issuer Trustee will grant a "floating charge" over the
                                  Trust Assets to the Security Trustee in order to secure
                                  the Issuer Trustee's obligations in respect of the Notes
                                  and the Transaction Documents. A "charge" is a proprietary
                                  interest created over property. A floating charge is a
                                  grant of a proprietary interest which "floats" over a
                                  group of assets which assets may change or be dealt with
                                  from time to time. A floating charge allows the person or
                                  entity granting the charge (the "chargor") to deal with
                                  the assets and to give third parties title to those assets
                                  free from any encumbrance, provided such dealings and
                                  transfers of title are in the ordinary course of the
                                  chargor's business. For a description of a floating charge

                                  the Class A Notes are also redeemed. See "RISK FACTORS--No
                                  Gross-Up; Tax Redemption."
 
Legal Investment
  Considerations................  The Offered Notes will not constitute "mortgage related
                                  securities" for purposes of the Secondary Mortgage Market
                                  Enhancement Act of 1984 ("SMMEA"). No representation is
                                  made as to whether the Offered Notes constitute legal
                                  investments under any applicable statute, law, rule,
                                  regulation or order for any entity whose investment
                                  activities are subject to investment laws and regulations
                                  or to review by certain regulatory authorities.
                                  Prospective purchasers are urged to consult with their

                                  status of the Offered Notes as legal investments for such
                                  purchasers. See "LEGAL INVESTMENT CONSIDERATIONS" herein.
 
Tax Status......................  In the opinion of Mayer, Brown & Platt, special tax
                                  counsel for the Trust, the Offered Notes will be
                                  characterized as debt for U.S. federal income tax
                                  purposes. Each Offered Noteholder, by acceptance of an
                                  Offered Note, will agree to treat the Offered Notes as
                                  indebtedness. See "UNITED STATES FEDERAL INCOME TAX
                                  CONSEQUENCES" herein.
 
                                  Payments of principal and Interest in respect of the
                                  Offered Notes will be made subject to withholding tax (if
                                  any) applicable to the Offered Notes without the Issuer
                                  Trustee being obliged to pay any additional amounts to the
                                  Offered Noteholders in respect of such withholding tax.
                                  See "RISK FACTORS--No Gross-Up; Tax Redemption."
 
ERISA Considerations............  Subject to the considerations discussed under "ERISA
                                  CONSIDERATIONS," the Offered Notes are eligible for
                                  purchase by employee benefit plans.
 
Ratings of the Offered Notes....  It is a condition to the issuance of the Class A Notes
                                  that they be rated "AAA" by Standard & Poor's Ratings
                                  Group, a division of The McGraw-Hill Companies ("Standard
                                  & Poor's"), "Aaa" by Moody's Investors Service, Inc.
                                  ("Moody's") and "AAA" by Fitch IBCA, Inc. ("Fitch").
                                  Moody's, Fitch and Standard & Poor's are referred to
                                  herein as the "Rating Agencies." It is a condition to the
                                  issuance of the Class B Notes that they be rated "AA-" by
                                  Standard & Poor's and "AA-" by Fitch. The security ratings
                                  of the Offered Notes should be evaluated independently
                                  from similar ratings on other types of securities. A
                                  security rating is not a recommendation to buy, sell or
                                  hold securities and may be subject to revision or
                                  withdrawal at any time by the Rating Agencies. See
                                  "RATINGS OF THE NOTES" herein.
 
Governing Law...................  The Notes and the Transaction Documents (other than the
                                  Security Trust Deed and certain of the Swap Agreements)
                                  are governed by, and shall be construed in accordance
                                  with, the laws of New South Wales, Australia. The Security
                                  Trust Deed is governed by, and shall be construed in
                                  accordance with, the laws of the Australian Capital
                                  Territory.
 
                                  The Issuer Trustee has, under the Note Trust Deed,
                                  submitted to the non-exclusive jurisdiction of the courts
                                  of New South Wales for all purposes in connection with the
                                  Offered Notes.
 
Risk Factors....................  In considering an investment in the Offered Notes,
                                  investors should recognize that there are risks associated
                                  with such an investment. See "Risk Factors" herein.

                               CASH FLOW SUMMARY
 
    THE FOLLOWING IS A BRIEF SUMMARY OF THE ALLOCATION OF CASHFLOWS IN RELATION
TO THE TRUST. THIS CASH FLOW SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE
TO THE DETAILED INFORMATION APPEARING ELSEWHERE IN THIS PROSPECTUS --SEE
"DESCRIPTION OF THE OFFERED NOTES" FOR A FULL DESCRIPTION OF CASHFLOW
ALLOCATION. TERMS DEFINED BELOW ARE DEFINED IN MORE DETAIL ELSEWHERE--THE
DEFINITIONS BELOW ARE FOR CONVENIENCE ONLY.
 
COLLECTIONS
 
    Amounts collected by or on behalf of the Issuer Trustee in respect of the
Trust are calculated for each Collection Period and include, for the relevant
Collection Period:
 
    1.  scheduled payments (of interest, principal and fees) and prepayments of
principal under the Housing Loans;
 
    2.  proceeds from enforcement of Housing Loans and related Mortgages (see
"CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS--Enforcement of Housing Loans");
 
    3.  amounts payable under Mortgage Insurance Policies with respect to losses
on Housing Loans and related Mortgages;
 
    4.  amounts received from an Approved Seller or the Servicer for breaches of
representations or undertakings; and
 
    5.  interest on amounts in the Collections Account.
 
    These amounts are known as "Collections" which will be attributed between
income and principal. The Collections attributed to income, less certain
amounts, are "Available Income". The Collections attributed to principal, less
certain amounts, are "Gross Principal Collections".
 
    The cashflow allocation methodology treats Available Income and Gross
Principal Collections in two separate "streams". Generally, the two streams are
treated separately. However, in some circumstances, principal will be treated as
income and applied in the income stream, and in other circumstances income will
be treated as principal and applied in the principal stream.
 
GROSS PRINCIPAL COLLECTIONS
 
    Gross Principal Collections are applied first to repay Westpac for any
Redraws funded by Westpac in the relevant Collection Period. The balance of
Gross Principal Collections remaining after such repayment of Westpac is known
as "Principal Collections." Those Principal Collections are applied:
 
    1.  First, to repay Westpac for any Redraws funded by Westpac to the extent
not previously reimbursed (I.E., not restricted to Redraws funded during the
relevant Collection Period);
 
    2.  Second, to repay amounts outstanding under the Redraw Facility
Agreement;
 
    3.  Third, to be treated as income to the extent necessary if there is
insufficient income for the Collection Period to make required income payments
(this application of principal as income is a "Principal Draw");
 
    4.  Fourth, to pay principal outstanding under the RFSs until repaid in
full;
 
    5.  Fifth, to pay principal outstanding under the Class A Notes and the RFS
Class A Notes. Those payments may be applied either sequentially or serially
with respect to Class B Notes, depending on whether certain threshold tests have
been satisfied.
 
    Initially all Principal Collections will be applied "sequentially," meaning
that such Principal Collections will be applied to the RFSs (if any), Class A
Notes and RFS Class A Notes (if any), pro rata, until such classes are paid in
full. The Class B Notes are then entitled to Principal Collections.
 
                                       29
<PAGE>
    If certain distribution tests have been met, Principal Collections will be
applied "serially," entitling the Class A Notes and the Class B Notes to share
in Principal Collections. There are two serial distribution tests which focus on
whether the subordination provided by the Class B Notes to the Class A Notes
effectively doubles from the initial level of subordination at the start of the
transaction, whether the distribution of Principal Collections is occurring
prior to a certain date and whether certain credit tests focusing on
delinquencies and losses on the Housing Loans have been met. For a complete
description of the serial distribution tests, see the definitions of "Serial
Method 1 Distribution Test" and "Serial Method 2 Distribution Test" set forth in
"DESCRIPTION OF THE OFFERED NOTES--Payments of Principal on the Notes."
 
    6.  Sixth, to pay principal outstanding under the Class B Notes under the
sequential or serial methods referred to above.
 
PRINCIPAL LOSSES
 
    It may be that principal losses are incurred in respect of a Housing Loan
during a Collection Period.
 
    If (i) a Borrower defaults; (ii) the relevant Housing Loan and related
Mortgage are enforced; and (iii) the amount recovered (after payment of
enforcement expenses) will not satisfy the Unpaid Balance of the Housing Loan,
there will be a "Liquidation Loss". A Liquidation Loss will usually comprise
both interest and principal. To the extent that it relates to principal, a
Liquidation Loss is known as a "Principal Loss". If, following a Principal Loss,
the relevant Mortgage Insurance Policy does not cover that loss and the Issuer
Trustee does not have a right to recover any amounts from an Approved Seller or
the Servicer due to a breach of representation or undertaking, there will be a
loss on the underlying principal in the pool. Such a loss is a "Mortgage
Shortfall". The total amount of all Mortgage Shortfalls in a Collection Period
is known as the "Principal Charge Off" for that Collection Period.
 
    Any Principal Charge Off for a Collection Period may be met by any excess
income which is available from the income stream for that purpose (as summarized
below). If the Principal Charge Off cannot be satisfied in full from that excess
income, the principal loss represented by the balance of the Principal Charge
Off which is not so satisfied must be "carried over" into succeeding periods.
This is a "Carryover Charge Off".
 
    Each Carryover Charge Off must be represented by a reduction in the
principal amount of the Notes. Thus, the principal amount of the Notes (the
"Invested Amount") is reduced:
 
        (a) First, in respect of Class B Notes; and
 
        (b) Second, if the Class B Notes are reduced to zero, PRO RATA, in
    respect of the Class A Notes, the RFSs, the RFS Class A Notes and the
    Principal Outstanding under the Redraw Facility.
 
    The "Stated Amount" of a Note is thus the Invested Amount of the Note less
the Carryover Charge Offs applied against it as set out above.
 
    Excess income may be used to recover principal which has been reduced
following a Carryover Charge Off. The application of income for this purpose is
summarized below.
 
INCOME COLLECTIONS
 
    Available Income is applied in the following order of priority:
 
        (a) First, in respect of the first Collection Period, to the Approved
    Seller for income received by the Issuer Trustee on the pool relating to the
    period prior to the Closing Date. This is the "Accrued Interest Adjustment";
 
        (b) Second, to Trust Expenses which have not previously been paid;
 
                                       30
<PAGE>
        (c) Third, to repay amounts outstanding under the Support Facilities
    (other than the Currency Swaps and fees under the Liquidity Facility
    Agreement);
 
        (d) Fourth, to repay Liquidity Draws under the Liquidity Facility
    Agreement;
 
        (e) Fifth, PARI PASSU and ratably, to interest on the Class A Notes, the
    RFSs and the RFS Class A Notes and to fees under the Redraw Facility
    Agreement; and
 
        (f) Sixth, to interest on the Class B Notes.
 
    These payments are "Total Payments".
 
    Any Available Income in excess of Total Payments for a Collection Period is
"Excess Available Income", and is applied in the following order of priority:
 
        (i) First, against Principal Charge Offs for the Collection Period;
 
        (ii) Second, PARI PASSU and ratably, against Carryover Charge Offs for
    Class A Notes, RFSs, RFS Class A Notes and fees or amounts owing under the
    Redraw Facility Agreement;
 
       (iii) Third, against Carryover Charge Offs for Class B Notes; and
 
        (iv) Fourth, to Principal Draws which have not previously been repaid.
 
    Any amount remaining after application of these payments is an "Excess
Collections Distribution", and will be paid to Westpac as beneficiary of the
Trust.
 
LIQUIDITY SUPPORT
 
    If there are insufficient interest Collections to meet Total Payments for a
Collection Period, principal may be used to provide liquidity by way of a
"Principal Draw" (see above).
 
   
    If Principal Draws are not available to meet Total Payments, a drawing must
be made under the Liquidity Facility Agreement up to its facility limit (being
A$79,000,000) to provide liquidity to allow Total Payments to be made.
    
 
CURRENCY SWAPS
 
    All payments required to be made to Offered Noteholders will be made in
Australian dollars to the Currency Swap Providers, who will swap the amounts
into US dollars.

                                  RISK FACTORS
 
    In addition to the matters described elsewhere in this Prospectus,
prospective investors should carefully consider the following factors before
deciding to invest in the Offered Notes.
 
LIMITED LIABILITY UNDER THE OFFERED NOTES
 
    The Offered Notes are debt obligations of the Issuer Trustee in its capacity
as trustee of the Trust. They are issued with the benefit of, and subject to the
Master Trust Deed, the Series Notice, the Security Trust Deed and the Note Trust
Deed. The Issuer Trustee's liability in respect of the Offered Notes is limited
to the assets of the Trust available in accordance with the terms of the Master
Trust Deed, the Series Notice, the Note Trust Deed and the Security Trust Deed
to meet its obligations in relation to the Offered Notes and, except in certain
limited circumstances, the Issuer Trustee will not be personally liable in
respect of the Offered Notes. See "THE ISSUER TRUSTEE--Limitation of Issuer
Trustee's Liability."
 
    In addition, the Offered Notes will not represent an interest in or
obligation of the Servicer, the Trust Manager, the Approved Sellers, the Note
Trustee, the Security Trustee or any of their respective affiliates (other than
the Issuer Trustee to the extent referred to above). The only obligations of the
foregoing entities with respect to the Offered Notes or any Housing Loan will be
the obligations of the Approved Sellers pursuant to certain limited
representations and warranties made with respect to the Housing Loans, of the
Servicer with respect to its servicing obligations under the Servicing Agreement
and the Trust Manager in respect of its undertakings in the Transaction
Documents. The Offered Notes will not be guaranteed or insured by any
governmental agency or instrumentality, or by the Issuer Trustee, the Servicer,
the Trust Manager, the Approved Sellers, the Note Trustee, the Security Trustee
or any of their respective affiliates. The Housing Loans are subject to certain
mortgage insurance policies, but only limited losses are covered. Housing Loans
insured by HLIC prior to December 12, 1997 will have the benefit of a
Commonwealth Government Guarantee. See "THE MORTGAGE INSURANCE POLICIES."
Proceeds of the assets included in the Trust (including the Housing Loans) will
be the sole source of payments on the Offered Notes, and there will be no
recourse to the Servicer, the Trust Manager, the Approved Sellers, the Note
Trustee, the Security Trustee or any other entity in the event that such
proceeds are insufficient or otherwise unavailable to make all payments provided
for under the Offered Notes.
 
RISK OF EQUITABLE ASSIGNMENT OF HOUSING LOANS RATHER THAN LEGAL ASSIGNMENT
 
    Although the Housing Loans and the related Mortgages could have been legally
assigned by the Seller Trustee to the Issuer Trustee, they will initially only
be equitably assigned until a Title Perfection Event (as defined below) occurs.
A "Title Perfection Event" in relation to the Housing Loans is the occurrence of
any of the following: (i) Westpac ceases to have a long term credit rating of at
least "BBB" from Standard & Poor's, "Baa2" from Moody's; and "BBB" from Fitch
(ii) an Insolvency Event occurs with respect to Westpac; and (iii) Westpac fails
to transfer Collections within five Business Days after receiving notice from
the Issuer Trustee or the Trust Manager to do so. Until such time, pursuant to
the Transaction Documents, the Issuer Trustee is not permitted to take any steps
to perfect legal title and it cannot, and will not, notify the Borrowers of the
equitable assignment of the Housing Loans to the Issuer Trustee. If a Title
Perfection Event occurs, the Issuer Trustee, with the assistance of the
Servicer, is required take such steps as are necessary to perfect the Issuer
Trustee's legal title in the Housing Loans.
 
    The delay in the notification to a Borrower of the assignment of the Housing
Loans to the Issuer Trustee may have the following consequences:
 
    (1) until a Borrower has notice of the assignment, that Borrower is not
bound to make payments under the relevant Housing Loan to anyone other than
Westpac and can obtain a valid discharge from Westpac. However, the Servicer, a
delegate of Westpac, will act as the initial Servicer of the Housing Loans and
is obligated to deal with all moneys received from the Borrowers in accordance
with the Servicing Agreement and the Master Trust Deed;
 
    (2) for so long as the Issuer Trustee holds only an equitable interest in
the Housing Loans, the Issuer Trustee's interest in them may become subject to
the interests of third parties created after the creation of
 
                                       34
<PAGE>
the Issuer Trustee's equitable interest but prior to it acquiring a legal
interest in the Housing Loans. However, the Servicer undertakes not to consent
to the creation or existence of any higher or equal ranking security interest
over the Mortgaged Property (the "Servicer's Security Undertaking"); and
 
    (3) for so long as the Issuer Trustee holds only an equitable interest in
the Housing Loans, it must join Westpac as a party to any legal proceedings
against any Borrower in relation to the enforcement of any Housing Loan. In this
regard, Westpac undertakes in the Servicing Agreement to co-operate with the
Servicer in connection with the enforcement of any Housing Loans. Westpac has
granted an irrevocable power of attorney to the Issuer Trustee to perfect its
interest in the Housing Loans.
 
    So long as the Issuer Trustee holds equitable title, rather than legal
title, to a Housing Loan, the Issuer Trustee's interest in such Housing Loan may
be impaired by the creation or existence of any higher or equal ranking security
interest over the related Mortgaged Property if the Servicer fails to adhere to
the Servicer's Security Undertaking. Such failure may result in losses to
Noteholders.
 
RISK OF LOSSES AND DELAYS FROM ENFORCEMENT OF THE HOUSING LOANS
 
    Substantial delays could be encountered in connection with the liquidation
of a Housing Loan and result in shortfalls in distributions to Noteholders to
the extent not covered by a Mortgage Insurance Policy or if the relevant
Mortgage Insurance Policy provider fails to perform its obligations. Further,
liquidation expenses such as legal fees, real estate taxes, and maintenance and
preservation expenses (to the extent not covered by a Mortgage Insurance Policy)
will reduce the net amounts recoverable by the Issuer Trustee from an enforced
Housing Loan and mortgage and will reduce Excess Available Income. In the event
any of the Mortgaged Properties fail to provide adequate security for the
related Housing Loans, Noteholders could experience a loss to the extent not
covered by a Mortgage Insurance Policy or if the relevant Mortgage Insurance
Policy provider fails to perform its obligations and the subordination of Excess
Available Income is not sufficient.
 
MORTGAGE INSURANCE POLICIES ARE SUBJECT TO EXCLUSIONS AND LIMITATIONS
 
    The liability of each of the Mortgage Insurers under the Mortgage Pool
Insurance Policy and the PMI Policies, as applicable, is subject to certain
exclusions. Each of them also has the right to cancel the coverage of, or
terminate its Mortgage Insurance Policy in respect of, a Housing Loan in certain
circumstances. The exclusions and rights vary among the different Mortgage
Insurance Policies and may affect the ability of the Issuer Trustee to make
timely and full payments of principal and Interest on the Notes. See "THE
MORTGAGE INSURANCE POLICIES" for further details.
 
RISKS ASSOCIATED WITH HIGH LVR HOUSING LOANS
 
   
    Approximately 32.79% of the Housing Loans by aggregate principal balance of
the related Housing Loans as of the CutOff Date, had an LVR in excess of 80%.
Housing Loans with higher LVRs may present a greater risk of delinquency.
Although each Housing Loan in the Trust with an LVR in excess of 80% is covered
by a PMI Policy which insures the full amount of the Unpaid Balance of the
related Housing Loan, if a Borrower fails to make payments under such a Housing
Loan and the applicable Mortgage Insurer cancels the relevant PMI Policy,
reduces the amount of a claim or fails to honor its obligation under the PMI
Policy, proceeds from a liquidation of such Housing Loan may be insufficient to
cover the Unpaid Balance thereof. As a result, Noteholders may experience losses
including Principal Charge Offs (as defined herein) with respect to the Offered
Notes. For a description of such coverage, see "THE MORTGAGE INSURANCE
POLICIES."
    
 
RISKS ASSOCIATED WITH WESTPAC'S ABILITY TO SET RATES ON VARIABLE RATE HOUSING
  LOANS AT ITS DISCRETION
 
    The interest rates with respect to the Variable Rate Housing Loans are not
tied to an objective interest index but rather may be set at the sole discretion
of Westpac, as originator of the Housing Loans. See "WESTPAC RESIDENTIAL LOAN
PROGRAM--Housing Loan Features." In the event that Westpac increases interest
rates on the Variable Rate Housing Loans, Borrowers may be unable to meet their
Scheduled Payments and accordingly, may become delinquent or may default on
their respective
 
                                       35
<PAGE>
Housing Loans. In addition, if such increase raises interest rates above market
interest rates, Borrowers may refinance their loans with another lender to
obtain a lower interest rate, which in turn could cause investors in the Offered
Notes to experience higher rates of principal prepayment on the Offered Notes
than anticipated.
 
ABILITY TO CHANGE HOUSING LOAN FEATURES MAY RESULT IN CHANGES TO THE MORTGAGE
POOL AND HIGHER RATES OF PRINCIPAL PREPAYMENT ON THE OFFERED NOTES.
 
    During the term of any Housing Loan, Westpac may from time to time or at the
request of the related Borrower change certain features of such Housing Loan. A
Borrower may request, among other changes, (a) additional funds with respect to
its Housing Loan (a "top up"), (b) a substitution or modification of the
security for the related Mortgage, (c) a switch to another type of Housing Loan
product, (d) a draw on principal repayments made in excess of scheduled
repayments (a "Redraw"), (e) an interest rate switch from variable to fixed or
vice versa, (f) reduced payments due to maternity or paternity leave, (g) a
repayment holiday if a prepayment of certain amounts has resulted in a buffer of
funds and (h) a switch from owner occupied to investment property status or vice
versa (which may result in a change in interest rates). For a more detailed
discussion of the various features available to Borrowers, see "WESTPAC
RESIDENTIAL LOAN PROGRAM-- Housing Loan Features."
 
    In addition, Westpac may initiate certain changes to the Housing Loans. Most
frequently, Westpac will change the Mortgage Rate. The change to the Mortgage
Rate can be either product or individual loan specific. In addition, subject to
certain conditions, Westpac may begin to offer additional product features with
respect to the Housing Loans which are not set forth herein. See "WESTPAC
RESIDENTIAL LOAN PROGRAM-Housing Loan Features-Additional Features."
 
    As a result of both Borrower and Westpac initiated changes, the
characteristics of the Housing Loans as of the Cut-Off Date may differ from the
characteristics of the Housing Loans at any other point in time. In addition,
certain types of modifications to a Housing Loan result in the removal of such
Housing Loan from the Mortgage Pool, which in turn could cause investors in the
Offered Notes to experience higher rates of principal prepayment on the Offered
Notes than anticipated. Similarly, if Westpac elects to change certain features
of the Housing Loans, Borrowers may elect to refinance their loan with another
lender to obtain more favorable features, which also could lead to higher
principal prepayment on the Offered Notes than expected. See "PREPAYMENT AND
YIELD CONSIDERATIONS."
 
RISKS OF CURRENCY EXCHANGE CONTROLS
 
    The Issuer Trustee will receive Australian dollar payments on the Housing
Loans in Australia and, under the Currency Swaps, is required to pay certain
collections to the Currency Swap Providers as required under the Series Notice.
It is possible that in the future Australia may impose exchange controls that
affect the availability of Australian dollar payments for making payments under
the Currency Swaps. The Offered Noteholders will bear the risk of the imposition
of foreign exchange controls by the Australian government that impact upon the
Issuer Trustee's ability to exchange the Collections for U.S. dollars. The
Issuer Trustee has no control over such risk, which will generally be affected
by economic and political events in Australia. If the Issuer Trustee does not
pay some or all of the amounts in Australian dollars which it is required by the
Transaction Documents to pay to the Currency Swap Providers under the Currency
Swaps, the Currency Swap Providers are only required to pay the U.S. dollar
equivalent of the amounts they actually receive. In such event, it is unlikely
that the Trust would have sufficient U.S. dollars to make the payments due on
the Offered Notes.
 
RISKS RELATED TO A TERMINATION OF THE SWAP AGREEMENTS
 
    By entering into the Swap Agreements, the Issuer Trustee intends to transfer
to the Interest Rate Swap Provider and Currency Swap Providers, as applicable,
the risks set forth below that the Trust would otherwise have with respect to
payments on the Offered Notes and the Housing Loans.
 
    (a) Currency Exchange Risk. Interest and principal on the Offered Notes is
payable in U.S. dollars and the Trust's primary source for funding its payments
on the Offered Notes is its collections on the
 
                                       36
<PAGE>
   
Housing Loans, which will be in Australian dollars. If the Currency Swap
Providers were to fail to perform under the Currency Swaps or were to be
discharged from such performance because of a default thereunder by the Trust,
the Issuer Trustee might have to exchange its Australian dollars for U.S.
dollars at an exchange rate that is less favorable to the Trust than the
original Swap Currency Exchange Rate (which is 1.603733 Australian dollars for
each U.S. dollar) and might therefore not have sufficient U.S. dollars to make
timely payments on the Offered Notes, even though the delinquency and loss
experience on the Housing Loans may be acceptable.
    
 
    (b) Risks Specific to the Variable Rate Basis Swap. The basis risk between
the floating rate obligations of the Trust (including Interest payable on the
Notes) and the variable administered rates set by Westpac will be hedged by
means of the Variable Rate Basis Swap. Pursuant to the Variable Rate Basis Swap,
each quarter the Interest Rate Swap Provider will pay the Issuer Trustee the
three month Bank Bill Rate plus a fixed margin and receive from the Issuer
Trustee the weighted average variable housing rate. The margin is fixed for the
life of the swap and will be set with regard for the ongoing expenses of the
Trust.
 
    If Westpac is downgraded below A-1+/A2/F-1+ by Standard & Poor's, Moody's or
Fitch, respectively, and fails to provide eligible collateral or arrange for a
suitable alternative swap provider, it will be an Additional Termination Event
under the terms of the ISDA Master Agreement. If the Variable Rate Basis Swap is
terminated, the Trust Manager is required to calculate each month the minimum
interest rate required to be set on the variable rate Housing Loans in order to
cover amounts payable by the Issuer Trustee (including anticipated Trust
Expenses and taxes) and amounts due to the Issuer Trustee, the Trust Manager,
the Servicer, the Liquidity Facility Provider, the Redraw Facility Provider and
the Noteholders (the "Threshold Rate"). In this situation, the Housing Loan
rates across Westpac's whole portfolio of loans of the same product type may be
set at above market interest rates on the variable housing loans to meet Trust
Expenses which could result in the affected Borrowers refinancing their loans
with another bank, which in turn could cause Offered Noteholders to experience
higher rates of principal repayment on the Offered Notes than anticipated. If
the Variable Rate Basis Swap is terminated, the Trust may be subject to
reinvestment risk to the extent that any payments and prepayments invested in
Authorized Investments do not earn a sufficient rate of interest to cover the
interest owing on the Notes.
 
    (c) Risks Specific to the Fixed Rate Swaps. Two Fixed Rate Swaps will be
used to hedge the interest rate risk between the floating rate obligations of
the Trust (including Interest payable on the Notes) and the discretionary fixed
rate set by Westpac on those Housing Loans being charged a fixed rate of
interest (a "Fixed Rate") (not including those loans with a Concessional Fixed
Rate). A Housing Loan is being charged a "Concessional Fixed Rate" when it has a
fixed rate of interest for the first 12 months, which converts to the standard
variable rate after that period. Loans subject to a Concessional Fixed Rate are
included under the Variable Rate Basis Swap. An amortizing Fixed Rate Swap will
be entered into on the Closing Date to hedge that portion of the pool earning a
Fixed Rate of interest as of the Cutoff Date. The Issuer Trustee will pay the
applicable daily weighted average fixed rate and receive the three month Bank
Bill Rate plus a fixed margin. The margin is fixed for the life of the swap and
has been set based on the actual margin on the underlying Fixed Rate Housing
Loans and the prevailing market rate existing on or about the Closing Date. A
further Fixed Rate Basis Swap will be entered into to hedge the interest rate
risk occurring when the Borrowers switch from a variable rate of interest to a
fixed rate of interest. Under that second Fixed Rate Basis Swap, the Issuer
Trustee will pay the applicable daily weighted average fixed rate and receive
the three month Bank Bill Rate plus a fixed margin. The margin is fixed for the
life of the swap.
 
    If Westpac is downgraded below A-1+/A2/F-1+ by Standard & Poor's, Moody's or
Fitch, respectively, and fails to provide eligible collateral or arrange for a
suitable alternative swap provider, it will be an Additional Termination Event
under the terms of the ISDA Master Agreement only at the discretion of the
Issuer Trustee, who shall make such decision at the direction of the Trust
Manager. If the swap remains in place, the Rating Agencies may consider
downgrading the Offered Notes and an investor may then be
 
                                       37
<PAGE>
holding Offered Notes which have been downgraded. If the swap is terminated, the
investor is exposed to the risk of the possible narrowing of the spread between
the customer rate applicable on the Housing Loans and the floating rate
obligations of the Trust (including the Interest on the Notes). If the relevant
Fixed Rate Basis Swap is terminated, the Trust will be subject to the risk that
the floating rate obligations of the Trust may change in such a way that the
discretionary fixed rate set by Westpac on those Housing Loans being charged a
fixed rate of interst will be insufficient to make payments on such floating
rate obligations.
 
DELINQUENCY AND DEFAULT RISK
 
    If Borrowers fail to make Scheduled Payments under Housing Loans when due
there is a possibility that the Issuer Trustee may have insufficient funds to
make full payments of Interest and principal due to the Noteholders.
 
    The Issuer Trustee's obligation to pay principal in respect of the Offered
Notes in full is limited by reference to, among other things, receipts by the
Issuer Trustee of amounts due under or in respect of the outstanding Housing
Loans. Noteholders must rely for payment of principal and Interest under the
Offered Notes on Borrowers making payments under the Housing Loans and on
amounts being available under the Mortgage Insurance Policies and any amounts
payable by an Approved Seller or the Servicer in respect of any breach of a
representation and warranty or undertaking respectively and, in addition, in the
case of Interest, on receipts of principal and required payments under the
Liquidity Facility. Furthermore, the Issuer Trustee is not required to make any
advances to cover shortfalls. See "DESCRIPTION OF THE OFFERED NOTES" and "THE
LIQUIDITY FACILITY."
 
    A wide variety of factors of a legal, economic, political or other nature
could affect the performance of Borrowers in making payments of principal and
interest under the Housing Loans. In particular, if interest rates increase
significantly, Borrowers may experience distress and increased default rates on
the Housing Loans may result. Under the Consumer Credit Legislation (as defined
herein), among other remedies, a court may order a Housing Loan to be varied on
the grounds of hardship. See "CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS." Any
such variance may reduce the principal or interest payable under a particular
Housing Loan.
 
    If a Borrower defaults on payments under a Housing Loan and the Servicer
enforces the Housing Loan and takes possession of the relevant Mortgaged
Property, many factors may affect the price for which the Mortgaged Property is
sold and the length of time required to realize the proceeds of sale. Any delay,
and any loss incurred as a result of the realized proceeds of the sale of a
Mortgaged Property being less than the amount due under the Housing Loan may
affect the ability of the Issuer Trustee to make payments, or the timing of
those payments, in respect of the Offered Notes, notwithstanding any amounts
that may be claimed under a Mortgage Insurance Policy or otherwise allocated
from Principal Collections or drawn under the Liquidity Facility.
 
RISK OF EARLY DEFAULTS
 
    Although little data is available and no empirical verification has been
made by the Trust Manager, the Underwriters or the Issuer Trustee, defaults on
mortgage loans, including mortgage loans similar to the Housing Loans, are
generally expected to occur with greater frequency in the early years of the
terms of mortgage loans.
 
PRINCIPAL PREPAYMENT AND YIELD CONSIDERATIONS
 
    The yield to maturity experienced by a Offered Noteholder may be affected by
the rate of payment of principal of the Housing Loans. The Trust may receive
early payments of principal on the Housing Loans and, therefore, pay Principal
Collections to the Noteholders earlier than would otherwise have been the case.
For example, early payments of principal may occur in the following situations:
 
    (1) receipt by the Issuer Trustee of enforcement proceeds due to a Borrower
having defaulted on its Housing Loan;
 
                                       38
<PAGE>
    (2) receipt by the Issuer Trustee of insurance proceeds in relation to a
claim under a Mortgage Insurance Policy in respect of a Housing Loan;
 
    (3) repurchase by Westpac of Housing Loans as a result of a breach by it of
certain representations (see "THE TRUST FUND--Representations and Warranties"
and "--Breach of Representations and Warranties");
 
    (4) receipt by the Trust of any net amount attributable to principal from
another WST trust established under the Master Trust Deed with respect to the
substitution of a Housing Loan;
 
    (5) repurchase of the Housing Loans as a result of a Clean-Up Offer or a
redemption for taxation or other reasons (see "DESCRIPTION OF THE OFFERED
NOTES--Clean-Up Offer" and "--Redemption of the Offered Notes for Taxation or
Other Reasons");
 
    (6) receipt of proceeds of enforcement of the Security Trust Deed prior to
the Maturity Date of the Notes (see "DESCRIPTION OF THE OFFERED
NOTES--Redemption of the Notes"); or
 
    (7) receipt of proceeds of the sale of Housing Loans if the Trust is
terminated while Offered Notes are outstanding (for example, if required by law)
and the Housing Loans are then either (a) repurchased by Westpac under its right
of first refusal or (b) sold to a third party.
 
    Additionally, in certain limited circumstances (for example, if the
principal amount of a Housing Loan is increased other than as a result of a
Redraw (see "DESCRIPTION OF THE OFFERED NOTES-- Description of the Redraw
Facility, the Redraw Funding Securities and the Class A RFS Notes")), the Issuer
Trustee may transfer Housing Loans which comprise assets of the Trust to another
WST trust established under the Master Trust Deed. The consideration for that
transfer, to the extent it constitutes principal, will form part of Gross
Principal Collections (as defined herein) during the related Collection Period
and will be distributed as if it were a prepayment of principal by the relevant
Borrower.
 
    Also, the Trust's principal payment experience may be affected by a wide
variety of factors, including general economic conditions, interest rates, the
availability of alternative financing and homeowner mobility. Furthermore,
unlike the United States, under Australian law, interest on loans used to
purchase a person's primary place of residence is not ordinarily deductible for
taxation purposes. Conversely, interest payments on mortgage loans and other
non-capital expenditures relating to investment properties that generate taxable
income are generally allowable as tax deductions. This is one contributing
factor to borrowers prepaying housing loans relating to owner-occupied
properties in Australia in a manner that differs from the United States. See
"CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS-- Treatment of Interest Payments
with respect to Australian Housing Loans".
 
    See "PREPAYMENT AND YIELD CONSIDERATIONS."
 
NO GROSS-UP; TAX REDEMPTION
 
    In the event that any withholding tax is imposed on payments of interest on
any of the Offered Notes, the holders of the Offered Notes will not be entitled
to receive grossed-up amounts to compensate for such withholding tax.
Consequently, there can be no assurance that the remaining payments on the
Housing Loans would be sufficient to make timely payments of Interest on and
payment of principal at the maturity date of the Offered Notes. In addition,
upon the occurrence of a Withholding Tax Event, the Issuer Trustee (at the
direction of the Trust Manager) may on any Payment Date simultaneously redeem in
whole but not in part, at the redemption prices specified herein, the affected
Class of Offered Notes in accordance with the procedures described under
"DESCRIPTION OF THE OFFERED NOTES--Redemption of the Offered Notes for Taxation
or Other Reasons" herein. Holders of 75% of the Invested Amount of a Class may
also elect not to redeem the affected Class of Offered Notes in the event of a
Withholding Tax Event.
 
REINVESTMENT RISK
 
    The Interest Rate Swap Agreements transfer the reinvestment risk detailed
below to the applicable Swap Provider. In the event that the Variable Rate Basis
Swap is terminated, the reinvestment risk will transfer back to the Issuer
Trustee. If a prepayment is received on a Housing Loan during any Collection
Period, interest at the then current interest rate on the Housing Loan will
cease to accrue on that part of
 
                                       39
<PAGE>
the Housing Loan prepaid from the date of the prepayment. The amount prepaid
will be invested in Authorized Investments for the balance of the Collection
Period at a rate that may be less than the then rate on the Housing Loan.
Interest will, however, continue to be payable in respect of an Invested Amount
of principal on the Offered Notes until the next Payment Date following the
prepayment. Accordingly, the difference between the rate earned on the prepaid
amount of the Housing Loan and the amount of interest payable on the Offered
Notes may affect the ability of the Issuer Trustee to pay interest in full on
the Offered Notes. Certain Principal Collections and the Liquidity Facility may
cover such shortfalls in whole or in part but there is no assurance that
sufficient amounts will be available. For further details see "DESCRIPTION OF
THE OFFERED NOTES--Available Income" and "--Principal Draws."
 
SERVICER RISK
 
    The appointment of the Servicer under the Master Trust Deed and Servicing
Agreement may be terminated under certain circumstances or the Servicer may
resign (see "DESCRIPTION OF THE SERVICING AGREEMENT"). If the Servicer is
removed for any reason, the Issuer Trustee is obligated to appoint a suitably
qualified person as Servicer whose appointment would not materially prejudice
the interests of Noteholders (an "Eligible Servicer") to assume responsibility
for servicing the Housing Loans in accordance with the Master Trust Deed and the
Servicing Agreement. There is no guarantee (a) that an Eligible Servicer will be
found who would be willing to service the Housing Loans on the terms of the
Master Trust Deed and the Servicing Agreement, in which case the Issuer Trustee
must act as the Eligible Servicer or (b) that an Eligible Servicer will be able
to service the Housing Loans with the same level of skill and competence as the
initial Servicer. The ability of the Eligible Servicer (whether it is the Issuer
Trustee or a third party) to perform the servicing functions under the Master
Trust Deed and Servicing Agreement would depend on the information and records
available to it.
 
SUBORDINATION OF THE CLASS B NOTES
 
    The rights of the holders of the Class B Notes to receive payments of
Interest on each Payment Date will be subordinated to such rights of the holders
of the RFSs (if any), Class A Notes, RFS Class A Notes (if any) and the Redraw
Facility Provider to the extent set forth herein. In addition, the rights of the
holders of the Class B Notes to receive distributions of principal on each
Payment Date generally will be subordinated to such rights of the holders of the
RFSs (if any) and the Redraw Facility Provider with respect to repayments
pursuant to Redraw Facility Agreement and to holders of the Class A Notes and
RFS Class A Notes (if any). Furthermore, any Principal Charge Offs will be
applied first in reduction of the principal balance of the Class B Notes.
 
    In the event that the Note Trustee is required by the Transaction Documents
or the Offered Notes to have regard to the interests of the Class A Noteholders
and the Class B Noteholders and where, in the opinion of the Note Trustee, there
is a conflict between the interests of the Class A Noteholders and the interests
of the Class B Noteholders, the Note Trustee shall have regard only to the
interests of the Class A Noteholders despite anything to the contrary in the
Transaction Documents.
 
PRIORITY OF RFSS AND RFS CLASS A NOTES OWNED BY AUSTRALIAN RESIDENT INVESTORS
 
    In certain limited circumstances, the Issuer Trustee will issue RFSs and RFS
Class A Notes, which will be issued to Australian resident investors only. The
RFSs will be senior to the Class A Notes with respect to payments of principal
and which will rank PARI PASSU with the Class A Notes with respect to Interest.
In addition, on each Payment Date, Gross Principal Collections will be used to
reimburse Westpac for any Redraws funded by Westpac during the related
Collection Period prior to payments being made on the Class A Notes.
Additionally, if RFSs are not repaid on the fifth Collection Determination Date
following the date such RFSs were issued, such RFSs will convert to RFS Class A
Notes. The RFS Class A Notes will rank PARI PASSU with the Class A Notes with
respect to payments of both principal and Interest. In addition, payments due on
the Redraw Facility, RFSs and RFS Class A Notes, if any, will be senior in right
of payment to the Class B Notes with respect to principal, Interest and fees. If
proceeds from the liquidation of the assets included in the Trust following the
enforcement of the Security Trust Deed are not sufficient to pay all
 
                                       40
<PAGE>
obligations of the Issuer Trustee in its capacity as trustee of the Trust,
Noteholders with a lower priority of payment are at a greater risk for losses on
their investment. See "DESCRIPTION OF THE OFFERED NOTES--Description of the
Redraw Facility, the Redraw Funding Securities and the RFS Class A Notes."
 
CREDIT ENHANCEMENT PROVIDES ONLY LIMITED PROTECTION AGAINST LOSSES
 
    Credit enhancement with respect to the Class A Notes will be provided by (i)
the Mortgage Insurance Policies, (ii) subordination of the Excess Available
Income and (iii) the subordination of payments on the Class B Notes to payments
to the Class A Notes. Credit enhancement with respect to the Class B Notes will
be provided by (i) the Mortgage Insurance Policies and (ii) subordination of the
Excess Available Income. Although the credit enhancement is intended to reduce
the risk of delinquent payments or losses to the Noteholders entitled to the
benefit thereof, the amount of such enhancement is limited, will decline and
could be depleted under certain circumstances prior to the payment in full of
the Offered Notes. As a result, the available credit enhancement may be
insufficient to reduce the risk of delinquent payments and losses to the
Noteholders. See "THE MORTGAGE INSURANCE POLICIES" and "DESCRIPTION OF THE
NOTES."
 
LIMITATIONS ON THE LIQUIDITY SUPPORT
 
    If on any Collection Determination Date, the Available Income of the Trust
is insufficient to meet Total Payments of the Trust for a Collection Period,
Principal Collections collected during such Collection Period may be used to
provide liquidity by way of a Principal Draw. If Principal Draws are not
available to meet Total Payments, a drawing must be made under the Liquidity
Facility up to the Liquidity Limit (as defined herein). In the event that there
are shortfalls in excess of the Liquidity Limit prior to the payment in full of
the Offered Notes, Noteholders may suffer losses. In addition, the Liquidity
Facility does not provide any credit enhancement with respect to the Offered
Notes. See "DESCRIPTION OF THE OFFERED NOTES--Principal Draws" and "THE
LIQUIDITY FACILITY."
 
EXERCISE OF CLEAN-UP OFFER MAY RESULT IN SHORTFALLS TO NOTEHOLDERS
 
    If at any time the aggregate Housing Loan Principal, expressed as a
percentage of the aggregate Housing Loan Principal as of the Cut-Off Date, is
less than 10%, then, if instructed by the Trust Manager, the Seller Trustee may
repurchase, on the following Payment Date, the equitable title to the Housing
Loans held by the Trust. The proceeds of sale will be applied by the Issuer
Trustee to repay moneys owing to Noteholders at that time in accordance with the
priorities for applying payments of Interest and principal between the Classes
of Notes. In the event that a Housing Loan is non-performing, the purchase price
for such Housing Loan will be based on the Fair Market Value. Fair Market Value
with respect to a Housing Loan may be less than the Unpaid Balance of such
Housing Loan. If a significant number of Housing Loans are non-performing, the
total proceeds from exercising the Clean-up Offer may be less than amounts owing
to Noteholders and Noteholders may suffer losses. See "DESCRIPTION OF THE
NOTES--Clean-up Offer."
 
REDEMPTION OF THE NOTES
 
    If an Event of Default occurs under the Security Trust Deed while the
Offered Notes are outstanding, the Security Trustee may (subject to the prior
written consent of the Note Trustee in accordance with the provisions of the
Security Trust Deed), and will (if so directed by the Note Trustee alone where
it is the only Voting Mortgagee or, otherwise by a resolution of 75% of the
Voting Mortgagees) enforce the security created by the Security Trust Deed. That
enforcement can include the sale of some or all of the Housing Loans. There is
no guarantee that the Security Trustee will be able to sell the Housing Loans
for their then current Unpaid Balance. Accordingly, the Security Trustee may not
be able to realize the full value of the Housing Loans and this may have an
impact upon the Issuer Trustee's ability to repay all amounts outstanding in
relation to the Notes. Any proceeds from the enforcement of the security will be
applied in accordance with the order of priority of payments as set out in the
Security Trust Deed. See "SECURITY FOR THE NOTES."
 
                                       41
<PAGE>
    If the Trust terminates while Notes are outstanding, Westpac has a right of
first refusal to acquire the Housing Loans. The price to be paid by Westpac for
performing and non-performing Housing Loans must be not less than their fair
market value. In the case of performing Housing Loans, the Issuer Trustee is
required to offer to sell them to Westpac under its right of first refusal for
their then Unpaid Balance. Where the fair market value of a Housing Loan is less
than its then Unpaid Balance, its acquisition by Westpac will be subject to
prior approval by holders of 75% of the votes of all Noteholders. This is
because in such circumstances there may be a shortfall in the amount available
to the Issuer Trustee to fully repay all amounts outstanding in relation to the
Notes. See "DESCRIPTION OF THE OFFERED NOTES-- Termination of the Trust."
 
GEOGRAPHIC CONCENTRATION MAY AFFECT PERFORMANCE
 
   
    Approximately 45.04%, 18.44% and 17.27% (by Cut-Off Date Principal Balance)
of the Housing Loans are secured by Mortgaged Properties in the regions of New
South Wales, Victoria and Queensland, respectively. To the extent that one or
more of such regions has experienced or may experience in the future weaker
economic conditions or greater rates of decline in real estate values than
Australia generally, such a concentration of the Housing Loans may be expected
to increase the risk of delinquencies and losses on the Housing Loans with
respect to such region. None of the Issuer Trustee, the Approved Sellers nor the
Servicer can quantify the impact of any recent property value declines on the
Housing Loans or predict whether, to what extent or for how long such declines
may continue.
    
 
CONSUMER CREDIT LEGISLATION
 
    Some of the Housing Loans are regulated by consumer credit legislation (the
"Consumer Credit Legislation"). Under that legislation, a Borrower has the right
to apply to a court to:
 
        (1) vary the terms of his or her Housing Loan on the grounds of hardship
    or that it is an unjust contract;
 
        (2) reduce or cancel any interest rate payable on the Housing Loan which
    is unconscionable;
 
        (3) have certain provisions of the Housing Loan or relevant Mortgage
    which are in breach of the legislation declared unenforceable; or
 
        (4) obtain restitution or compensation from either Westpac or, after a
    Title Perfection Event, the Issuer Trustee, in relation to any breaches of
    the Consumer Credit Legislation in relation to the Housing Loan or the
    relevant Mortgage.
 
    Any such order may affect the timing or amount of interest or principal
payments or repayments under the relevant Housing Loan (which might in turn
affect the timing or amount of Interest or principal payments or repayments
under the Offered Notes).
 
    In addition, a mortgagee's ability to enforce a mortgage which is subject to
the Consumer Credit Legislation is limited by various demand and notice
procedures which are required to be followed. For example, as a general rule
enforcement cannot occur unless the relevant default is not remedied within 30
days after a default notice is given. Borrowers may also be entitled to initiate
negotiations with the mortgagee for a postponement of enforcement proceedings.
Such procedures and negotiations may also affect the timing or amount of
interest or principal payments or repayments under the Housing Loans.
 
    Breaches of the Consumer Credit Legislation may also lead to civil penalties
or criminal fines being imposed on Westpac, for so long as it holds legal title
to the Housing Loans and the Mortgages. If the Issuer Trustee acquires legal
title, it will then become primarily responsible for compliance with the
Consumer Credit Legislation. The Issuer Trustee will (subject to limited
exceptions) be indemnified out of the assets of the Trust for its liabilities
under the Consumer Credit Legislation. If the Issuer Trustee is
 
                                       42
<PAGE>
indemnified with respect to such liabilities out of the assets of the Trust,
proceeds of the Trust may be insufficient to make all payments provided for
under the Offered Notes.
 
    Westpac will give, or has given, certain representations and warranties that
the Housing Loans and related Mortgages comply in all material respects with the
Consumer Credit Legislation in force at the time documents were entered into.
The representations and warranties are set forth in "THE TRUST
FUND--Representations and Warranties." The Servicer has undertaken to comply
with the Consumer Credit Legislation in connection with servicing the Housing
Loans and related Mortgages where failure to do so would have an Adverse Effect.
An "Adverse Effect" is an event which will materially and adversely affect the
amount of any payment to be made to any Noteholder, or will materially and
adversely affect the timing of such payment. In certain circumstances the Issuer
Trustee may have the right to claim damages from Westpac or the Servicer, as the
case may be, where the Issuer Trustee suffers a loss in connection with a breach
of the Consumer Credit Legislation which is caused by a breach of a relevant
representation or undertaking. See "CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS."
 
RISK OF COMMINGLING
 
    Collections under the Housing Loans are received by Westpac or the Servicer.
As described in "DESCRIPTION OF THE OFFERED NOTES--Collections," provided that
Westpac has a short term rating of at least "A-1+" from Standard & Poor's, "P-1"
from Moody's and "F-1+" from Fitch and the Collections Account is maintained
with Westpac or a subsidiary of Westpac, neither Westpac nor the Servicer is
required to pay the Collections into the Collections Account until two (2)
Business Days before the relevant Payment Date. If Westpac does not have the
relevant rating, Collections must be paid into the Collections Account within
five (5) Business Days (if the Collections Account is with Westpac or one of its
subsidiaries) or two (2) Business Days (in any other case) following receipt. In
each of these circumstances, the Collections may be commingled with the assets
of the Servicer or Westpac (as the case may be) and, in the event of the
insolvency of Westpac or the Servicer (as relevant), the Issuer Trustee may only
be able to claim those Collections as an unsecured creditor of the insolvent
company.
 
LIMITED LIQUIDITY
 
    There will be no market for the Offered Notes prior to the issuance thereof,
and there can be no assurance that a secondary market will develop, or if it
does develop, that it will provide the Offered Noteholders with liquidity of
investment or that it will remain for the term of any Offered Notes. The
Underwriters presently expect to make a secondary market in the Offered Notes,
but have no obligation to do so.
 
RATINGS OF THE NOTES; FACTORS AFFECTING ABILITY TO MAINTAIN RATINGS
 
    It is a condition to the issuance of the Class A Notes that they be rated
"Aaa" by Moody's, "AAA" by Standard & Poor's and "AAA" by Fitch and that the
Class B Notes be rated at least "AA-" by Standard & Poor's and "AA-" by Fitch. A
rating is not a recommendation to purchase, hold or sell the Offered Notes,
inasmuch as such rating does not comment as to market price or suitability for a
particular investor. The rating of the Offered Notes addresses the likelihood of
the payment of principal and interest on the Offered Notes pursuant to their
terms. There is no assurance that a rating will remain for any given period of
time or that a rating will not be lowered or withdrawn entirely by a Rating
Agency if in its judgment circumstances (including without limitation a
reduction in the credit rating of the Interest Rate Swap Provider, the Currency
Swap Providers, the Mortgage Insurance Providers or a reduction in the foreign
currency rating of Australia) in the future so warrant. The ratings of the
Offered Notes will be based primarily on the creditworthiness of the Housing
Loans, the subordination provided by the Class B Notes with respect to the Class
A Notes, the availability of Excess Available Income, if any, the Mortgage Pool
Insurance Policy and the PMI Policies, the availability of the Liquidity
Facility, the creditworthiness of the Interest Rate Swap Provider, the Currency
Swap Providers and the Mortgage Insurers and the foreign

currency rating of Australia. In the context of an asset securitization, the
foreign currency rating of a country reflects, in general, a Rating Agency's
view of the likelihood that cash flow on the assets in such country's currency
will be permitted to be sent outside of that country.
 
BOOK-ENTRY NOTES
 
    Issuance of the Offered Notes in book-entry form may reduce the liquidity of
such Notes in the secondary trading market since investors may be unwilling to
purchase Offered Notes for which they cannot obtain physical certificates. Since
transactions in the Offered Notes can be effected only through DTC, Cedel,
Euroclear, participating organizations, indirect participants and certain banks,
the ability of a Note Owner (as defined herein) to pledge an Offered Note to
persons or entities that do not participate in the DTC, Cedel or Euroclear
systems or otherwise to take actions in respect of such Offered Notes, may be
limited due to lack of a physical certificate representing the Offered Notes.
Note Owners may experience some delay in their receipt of distributions of
interest and principal on the Offered Notes since such distributions will be
forwarded by the Principal Paying Agent to DTC and DTC will credit such
distributions to the accounts of its Participants (as defined herein) which will
thereafter credit them to the accounts of Noteholders either directly or
indirectly through indirect participants. See "DESCRIPTION OF THE OFFERED
NOTES--Book-Entry Registration" herein.
 
OTHER CONSIDERATIONS
 
    There is no assurance that the market value of the Housing Loans will at any
time be equal to or greater than the Invested Amount of the Notes then
outstanding, plus accrued interest thereon. Moreover, upon an Event of Default
under the Security Trust Deed and a sale of the Trust Assets, the Security
Trustee, the Note Trustee, the Liquidity Facility Provider, the Swap Providers
and any other service provider generally will be entitled to receive the
proceeds of any such sale to the extent of unpaid fees and expenses and other
amounts owing to such persons prior to distributions to holders of the Notes.
After such payment of fees and expenses, the remaining proceeds thereof may be
insufficient to pay in full the principal of and interest on the Notes.
 
                             FORMATION OF THE TRUST
 
WESTPAC SECURITISATION TRUST PROGRAMME
 
    The Westpac Securitisation Trust Programme was established pursuant to the
Master Trust Deed for the purpose of enabling Westpac Securities Administration
Limited, as trustee of each Trust established pursuant thereto, to invest in
pools of consumer assets originated from time to time by the Westpac Banking
Corporation group (the "Westpac Group"). The Master Trust Deed provides for the
creation of an unlimited number of WST trusts. Each WST trust will be a separate
and distinct trust fund and will be created subject to the Master Trust Deed and
a supplemental series notice establishing specific provisions of the relevant
WST trust and the instruments to be issued by that trust. The Trust Assets are
not available to meet the liabilities of any other WST trust formed under the
Master Trust Deed. Likewise, the assets of any other trust formed under the
Master Trust Deed are not available to meet the liabilities of the Series
1998-1G WST Trust. Multiple classes of notes may be issued by the Issuer Trustee
in relation to each WST trust that differ among themselves as to priority of
payments and ratings.
 
SERIES 1998-1G WST TRUST
 
   
    The detailed terms of the Trust will be as set out in the Series Notice and
the Master Trust Deed. The Master Trust Deed establishes the general framework
under which WST trusts may be established from time to time. It does not
actually establish any trusts. To establish the Trust, the Trust Manager and the
Issuer Trustee have executed a notice of creation of trust dated on or about
      (the "Notice of Creation of Trust").
    
 
                                       44
<PAGE>
    In order to supplement the general framework under the Master Trust Deed
with respect to the Trust, all relevant parties (including the Trust Manager,
the Issuer Trustee and each Approved Seller) will execute the Series Notice,
which (among other things) specifies the details of the Notes, establishes the
cashflow allocation, sets out various representations and undertakings of the
parties specific to the Housing Loans, which are additional to those in the
Master Trust Deed, and amends the Master Trust Deed to the extent necessary to
give effect to the specific aspects of the Trust and the issue of the Offered
Notes.
 
    The Transaction Documents should therefore be read together when determining
the rights, powers and obligations of the Issuer Trustee, the Trust Manager and
the Approved Sellers in relation to the Trust. The Master Trust Deed and a form
of the Series Notice have been filed as exhibits to the Registration Statement
of which this Prospectus is a part. The summaries herein do not purport to be
complete and are subject to the provisions of such documents.
 
    The issuance of the Offered Notes will fund the purchase by the Trust of a
pool of residential housing loans originated by Westpac, which will be specified
in a Sale Notice from each of Westpac in its capacity as originator of the
Housing Loans or Westpac Securities Administration Limited in its capacity as
trustee of any other WST trusts established under the Master Trust Deed (in that
capacity, the "Seller Trustee"). The Seller Trustee owes a fiduciary duty to
Westpac, the entity which is the beneficiary of each "warehouse" trust
established under the Master Trust Deed.
 
    In addition, the Trust may issue certain additional debt securities as
discussed herein under "DESCRIPTION OF THE OFFERED NOTES--Description of the
Redraw Facility, the Redraw Funding Securities and the RFS Class A Notes."
 
TRUST ASSETS
 
    The Trust Assets will include:
 
        1.  a pool of Housing Loans, including all monies at any time paid or
    payable thereon or in respect thereof from and after the Cut-Off Date with
    respect to payments of principal and after the Closing Date with respect to
    payments of interest;
 
        2.  rights under certain insurance policies with respect to the Housing
    Loans;
 
        3.  amounts on deposit in certain accounts established pursuant to the
    Master Trust Deed, including the Collections Account and amounts invested in
    Authorized Investments; and
 
        4.  the Issuer Trustee's rights under the Transaction Documents.
 
                             SECURITY FOR THE NOTES
 
CHARGE
 
   
    Pursuant to the Security Trust Deed, dated on or about       , 1998 among
the Issuer Trustee, the Trust Manager, the Note Trustee and the Security
Trustee, the Issuer Trustee will grant a first ranking floating charge, to be
registered with the Australian Securities Commission, over all of the Trust
Assets in favor of Perpetual Trustee Company Limited (ACN 000 001 007) (the
"Security Trustee"), a company within the Perpetual group with its holding
company being Perpetual Trustees Australia Limited (ACN 000 431 827), in order
to secure the Issuer Trustee's obligations to the Offered Noteholders, the Note
Trustee, the Trust Manager, the Interest Rate Swap Provider, the Currency Swap
Providers, the Security Trustee, each Paying Agent, each other provider of a
Support Facility (other than any provider of a Mortgage Insurance Policy), the
Approved Sellers in respect of any Accrued Interest Adjustment (as defined
herein), to Westpac in respect of Redraws, to the holders of the RFSs (if any)
and the holders of the RFS Class A Notes (if any) (such creditors, together the
"Mortgagees").
    
 
                                       45
<PAGE>
SECURITY TRUSTEE
 
    The Security Trustee is appointed to act as trustee on behalf of the
Mortgagees on the terms and conditions of the Security Trust Deed. It holds the
benefit of the charge over the Trust Assets in trust for each Mortgagee in
accordance with the terms and conditions of the Security Trust Deed.
 
    Subject to the provisions of the Security Trust Deed, if there is a conflict
between the duties owed by the Security Trustee to any Mortgagees or class of
Mortgagees, the Security Trustee must give priority to the interests of the
holders of the RFSs (if any), the RFS Class A Notes (if any), the Class A
Noteholders and the Class B Noteholders (which in the case of the Class A
Noteholders and the Class B Noteholders shall be determined by the Note Trustee
acting on their behalf). Subject to the provisions of the Security Trust Deed
(other than the provision in the previous sentence), the Security Trustee must
give priority to the interests only of the Class A Noteholders, the holders of
the RFSs (if any) and the holders of the RFS Class A Notes (if any) if, in the
Security Trustee's opinion, there is a conflict between the interests of Class A
Noteholders, the holders of the RFSs (if any) and the holders of the RFS Class A
Notes (if any) and the interests of the Class B Noteholders or other Mortgagees.
Provided that the Security Trustee acts in good faith, it shall not incur any
liability to any Mortgagee for giving effect or seeking to give effect to the
preceding provisions of this paragraph.
 
    The Security Trustee has had no involvement in the preparation of any part
of this Prospectus, other than the particular reference to the Security Trustee
in this section and the disclosure of additional provisions of the Security
Trust Deed set forth herein. The Security Trustee makes no statement or
representation in this Prospectus, has not authorized or caused the issue of any
part of it and takes no responsibility for any part of it.
 
    The Security Trustee does not guarantee the success of the Offered Notes nor
the payment of principal or Interest on the Offered Notes.
 
NATURE OF SECURITY
 
    If a company grants a fixed security over any of its assets, those assets
may not be dealt with by such company without the consent of the relevant
mortgagee. In this way, the security is said to "fix" over the specific assets.
Fixed securities are usually given over real property, marketable securities and
other assets which will not be dealt with by the company.
 
    Unlike fixed securities, floating charges do not attach to specific assets
but instead "float" over a class of assets which may change from time to time,
allowing the person or entity granting the charge (the "chargor") to deal with
those assets and to give third parties title to those assets free from any
encumbrance in the event of sale, discharge or modification, provided such
dealings and transfers of title are in the ordinary course of a chargor's
business. The security created by the Security Trust Deed is a floating charge
over the Trust Assets. The Security Trust Deed provides that the Issuer Trustee
may not deal with the assets of the Trust subject to the floating charge, except
in the ordinary course of its business. It is common in Australia for special
purpose securitization vehicles to give floating charges rather than fixed
charges. If the Issuer Trustee disposes of any of the Trust Assets (including
any Housing Loan) in the ordinary course of its business, the acquirer of that
property will take them free of the floating charge.
 
    The floating charge created by the Security Trust Deed may "crystallize" and
become a fixed charge over the relevant class of assets owned by the Issuer
Trustee at the time of crystallization. Crystallization will occur automatically
following the occurrence of specific events set out in the Security Trust Deed,
including, among other events, notice to the Issuer Trustee from the Security
Trustee following an event of default. See "CERTAIN LEGAL ASPECTS OF THE HOUSING
LOANS" and "APPENDIX I-- GLOSSARY OF AUSTRALIAN LEGAL TERMS" herein.
 
                                       46
<PAGE>
ENFORCEMENT
 
    The Security Trustee must promptly convene a meeting of the Voting
Mortgagees (as defined herein) after it receives notice, or has actual knowledge
of, an Event of Default (as defined herein). See "DESCRIPTION OF THE OFFERED
NOTES--Events of Default; Rights Upon Event of Default." The Security Trustee
may waive (such waiver, being subject to the prior written consent of the Note
Trustee in accordance with the provisions of the Security Trust Deed), an Event
of Default before it is required to convene a meeting of Mortgagees if that
Event of Default is not (in the opinion of the Security Trustee) materially
prejudicial to the Mortgagees' interests.
 
    At the meeting, the Voting Mortgagees must vote by Extraordinary Resolution
(being a resolution passed at a duly convened meeting by a majority consisting
of not less than 75% of the votes capable of being cast by Voting Mortgagees
present in person or by proxy or by written resolution signed by all of the
Voting Mortgagees) on whether to direct the Security Trustee to:
 
        (1) declare the charge to be enforceable;
 
        (2) declare the Secured Moneys (as defined herein) (including amounts
    outstanding under the Notes, plus accrued and unpaid interest) immediately
    due and payable;
 
        (3) crystallize the floating charge created under the Security Trust
    Deed in relation to any or all of the Secured Property (for a description of
    the crystallization process, see "--Nature of Security" above); and/or
 
        (4) appoint a receiver over the Trust's assets or itself exercise the
    powers that a receiver would otherwise have under the Security Trust Deed.
 
    "Secured Moneys" means all money which the Issuer Trustee (whether alone or
with another person) is or at any time may become actually or contingently
liable to pay to or for the account of any Mortgagee (whether alone or with
another person) for any reason whatever under or in connection with a
Transaction Document.
 
    Every question submitted to a meeting shall be decided in the first instance
by a show of hands and in case of equality of votes the chairman shall both on a
show of hands and on a poll have a casting vote in addition to the vote or votes
(if any) to which he may be entitled as Voting Mortgagee or as a Representative
(as defined herein). On a show of hands, every person holding, or being a
Representative holding or representing other persons who hold, Secured Moneys
shall have one vote except that the Note Trustee shall represent each Noteholder
who has directed the Note Trustee to vote on its behalf under the Note Trust
Deed. On a poll, every person who is present shall have one vote for US $10,000
(but not part thereof) of the Secured Moneys that he holds or in which he is a
Representative. A "Representative" is in the case of any Noteholder, a person or
body corporate appointed as a proxy for that Noteholder.
 
    A resolution of all the Voting Mortgagees (including an Extraordinary
Resolution) may be passed, without any meeting or previous notice being
required, by an instrument or notes in writing which have been signed by all of
the Voting Mortgagees.
 
    The Security Trustee cannot exercise the powers referred to above unless
directed by an Extraordinary Resolution in the manner outlined above. The
Security Trustee is not obligated to act unless it obtains an indemnity from the
Voting Mortgagees and funds have been deposited on behalf of the Security
Trustee to the extent to which it may become liable for the relevant enforcement
actions. For so long as the Note Trustee is the only Voting Mortgagee it may
direct the Security Trustee to do any act which the Security Trustee is required
to do, or may only do, at the direction of an Extraordinary Resolution of Voting
Mortgagees. Neither the Security Trustee nor the Trust Manager may call a
meeting of Voting Mortgagees while the Note Trustee is the only Voting
Mortgagee, unless the Note Trustee otherwise consents.
 
                                       47
<PAGE>
    The Note Trustee will be the only Voting Mortgagee for so long as the
amounts outstanding under the Offered Notes are 75% or more of all Secured
Moneys.
 
    No Mortgagee is entitled to enforce the charge under the Security Trust
Deed, or appoint a receiver or otherwise exercise any power conferred by any
applicable law on charges, other than in accordance with the Security Trust
Deed.
 
PRIORITIES UNDER THE SECURITY TRUST DEED
 
    The proceeds from the enforcement of the Security Trust Deed (which will not
include amounts required by law to be paid to the holder of any prior ranking
security interest, the proceeds of or amounts credited to the collateral account
under the Liquidity Facility and payable to the Liquidity Facility Provider and
the proceeds of cash collateral lodged with and payable to a provider of a Swap
Agreement or provider of another Support Facility to the Issuer Trustee) are to
be applied in the order of priority set forth below, subject to any other
priority which may be required by statute or law. Priority of proceeds in
enforcement over secured creditors includes certain federal taxes, unpaid wages,
long service leave, annual leave and similar employee benefits and certain
auditor's fees.
 
        (1) first, to pay all costs, charges, expenses and disbursements
    properly incurred in the exercise of any power by the Security Trustee, the
    Note Trustee, a receiver or an attorney or other amounts (other than those
    referred to in paragraph (4) below) payable to the Security Trustee or the
    Note Trustee under the Security Trust Deed;
 
        (2) second, to pay PARI PASSU and rateably:
 
        (i) any fees and other expenses (including Trust Expenses) due to the
    Security Trustee, the Note Trustee or the Principal Paying Agent;
 
        (ii) any fees and unpaid expenses, due to the Issuer Trustee; and
 
       (iii) the receiver's remuneration;
 
        (3) third, to pay PARI PASSU and rateably any unpaid Accrued Interest
    Adjustment due to an Approved Seller;
 
        (4) fourth, to pay PARI PASSU and rateably:
 
        (i) all Secured Moneys (as defined herein) owing to the providers of
    each Support Facility (other than the Currency Swap Providers);
 
        (ii) all Secured Moneys owing to the holders of RFSs (if any);
 
       (iii) all Secured Moneys owing to the holders of RFS Class A Notes (if
    any);
 
        (iv) all Secured Moneys owing to the Class A Noteholders (as at the date
    of payment);
 
        (v) all Secured Moneys owed by the Issuer Trustee as trustee of the
    Trust to a WST trust other than the Trust;
 
        (vi) all Secured Moneys owing in relation to any Redraws made by Westpac
    for which it has not been reimbursed under the Transaction Documents; and
 
       (vii) all Secured Moneys owing to the Currency Swap Providers under a
    confirmation relating to the Class A Notes (but without double counting with
    payments under sub-paragraph (iv));
 
        (5) fifth, all Secured Moneys owing to the Class B Noteholders (as at
    the date of payment) and to the Currency Swap Providers under a confirmation
    relating to the Class B Notes, but without double counting;
 
                                       48
<PAGE>
        (6) sixth, to pay PARI PASSU and rateably any amounts not covered above
    owing to any Mortgagee under any Transaction Document;
 
        (7) seventh, to pay the holder of any subsequent security interest over
    the assets charged by the Security Trust Deed of which the Security Trustee
    has notice of the amount properly secured by the security interest; and
 
        (8) eighth, to pay any surplus to the Issuer Trustee to be distributed
    in accordance with the Master Trust Deed.
 
    The surplus will not carry interest. If the Security Trustee pays the
surplus to the credit of an account in the name of the Issuer Trustee with any
bank carrying on business in Australia, the Security Trustee, receiver,
Mortgagee or attorney (as the case may be) will be under no further liability in
respect of it.
 
    The "Accrued Interest Adjustment" represents interest and fees which have
accrued on the relevant Housing Loans but which are unpaid as at (and excluding)
the Closing Date, and all amounts received by the relevant Approved Seller under
those Housing Loans applied by the Servicer to payment of interest and fees
under those Housing Loans for the period from (but excluding) the Cut-Off Date
to (but excluding) the Closing Date. During the period between the Cut-Off Date
and the Closing Date, the Housing Loans continue to be owned by the Approved
Sellers. However, any Collections with respect to the period from the Cut-Off
Date through the Closing Date will not be paid back to Westpac until after the
assignment of the Housing Loans to the Trust. The purchase price for the Housing
Loans excludes any such accrual. Therefore, an amount equal to that accrued
interest and fees and Collections in respect of interest and fees for the period
between the Cut-Off Date and the Closing Date will be paid to the Approved
Sellers on the first Payment Date as a priority payment from Total Available
Funds.
 
SECURITY TRUSTEE'S FEES AND EXPENSES
 
    The Issuer Trustee shall reimburse the Security Trustee for all costs and
expenses of the Security Trustee properly incurred in acting as Security
Trustee. The Security Trustee shall be entitled to a fee payable quarterly (the
"Security Trustee Fee") in the amount agreed from time to time by the Issuer
Trustee, the Security Trustee and the Trust Manager. The Issuer Trustee has
agreed to indemnify the Security Trustee against any loss, cost, charge,
liability, expense or damage under or in relation to the Transaction Documents,
except where arising from the Security Trustee's fraud, negligence or willful
default.
 
RETIREMENT AND REMOVAL
 
    Subject to the appointment of a successor Security Trustee, the Security
Trustee may retire on three months' notice in writing to the Issuer Trustee, the
Trust Manager, the Note Trustee and the Rating Agencies. The Security Trustee
may resign in favor of a successor Security Trustee only if the Rating Agencies
confirm that such resignation will not cause a withdrawal, downgrade or
qualification of the ratings of the Offered Notes.
 
    Subject to the appointment of a successor Security Trustee and prior notice
being given to each of the Rating Agencies, an Extraordinary Resolution of the
Voting Mortgagees may at any time remove the Security Trustee.
 
    Subject to the appointment of a successor Security Trustee and prior notice
being given to each of the Rating Agencies, the Trust Manager may remove the
Security Trustee if any of the following occurs in relation to the Security
Trustee: (i) an Insolvency Event occurs in relation to the Security Trustee in
its personal capacity; (ii) the cessation by the Security Trustee of its
business; (iii) the failure by the Security Trustee to remedy within 14 days
after written notice by the Trust Manager any material breach of duty on the
part of the Security Trustee; or (iv) if without the prior written consent of
the Trust Manager there occur certain changes in the control or management of
the Security Trustee.
 
                                       49
<PAGE>
    Upon notice of resignation or removal of the Security Trustee, the Trust
Manager has the right to appoint a successor Security Trustee who has been
previously approved by an Extraordinary Resolution of the Voting Mortgagees and
who accepts the appointment. If no successor Security Trustee is appointed
within 30 days after notice, the retiring Security Trustee may on behalf of the
Mortgagees appoint a successor Security Trustee (other than Westpac or a related
corporation of Westpac) who accepts the appointment. There are currently several
third party security trustee organizations in Australia which may be available
to replace a resigning or removed security trustee.
 
ADDITIONAL PROVISIONS OF THE SECURITY TRUST DEED
 
    The Security Trust Deed may be amended by the Issuer Trustee and the
Security Trustee with the written approval of the Trust Manager and the Note
Trustee in the manner (and subject to the restrictions) set out in the Security
Trust Deed.
 
    The Security Trust Deed contains a range of provisions regulating the scope
of the Security Trustee's duties and liability. These include the following:
 
        (1) The Security Trustee is not responsible for the adequacy or
    enforceability of the Security Trust Deed or other Transaction Documents.
 
        (2) The Security Trustee is not required to exercise its powers under
    the Security Trust Deed without being directed to do so by the Note Trustee
    or by an Extraordinary Resolution (as referred to above) of the Voting
    Mortgagees.
 
        (3) The Security Trustee may rely on documents provided by the Issuer
    Trustee or Trust Manager and the advice of consultants and advisors.
 
        (4) The Security Trustee is not required to monitor whether an event of
    default has occurred or compliance by the Issuer Trustee or Trust Manager
    with the Transaction Documents or their other activities.
 
        (5) The Security Trustee is not required to do anything unless its
    liability is limited in a manner satisfactory to it.
 
        (6) The Security Trustee need not give Mortgagees information concerning
    the Issuer Trustee which comes into the possession of the Security Trustee.
 
        (7) The rights, remedies and discretion of the Noteholders including all
    rights to vote or give instructions or consents to the Security Trustee and
    to enforce its undertakings and warranties may only be exercised by the Note
    Trustee on behalf of the Class A and Class B Noteholders and the Security
    Trustee may rely on any instructions or directions given to it by the Note
    Trustee as being given on behalf of the Noteholders without inquiry about
    compliance with the Note Trust Deed.
 
        (8) The Security Trustee has no duties or responsibilities except those
    expressly set out in the Security Trust Deed or any collateral security.
 
        (9) Any action taken by the Security Trustee under the Security Trust
    Deed or any collateral security binds all the Mortgagees.
 
        (10) Each Mortgagee must make its own independent investigations,
    without reliance on the Security Trustee, as to the affairs of the Issuer
    Trustee and whether or not to take action under any Transaction Document.
 
        (11) The Security Trustee in its capacity as a Mortgagee can exercise
    its rights and powers as such as if it were not acting as the Security
    Trustee. It and its affiliates may engage in any kind of business with the
    Issuer Trustee, the Trust Manager, Mortgagees and others as if it were not
    Security Trustee and may receive consideration for services in connection
    with any Transaction Document or otherwise without having to account to the
    Mortgagees.

                                 THE TRUST FUND
 
GENERAL
 
   
    The Housing Loans are expected to include 21,132 Housing Loans secured by
registered first ranking mortgages (collectively, the "Mortgages") on Mortgaged
Properties located in Australia. This subsection describes generally the
characteristics of the Housing Loans. The Mortgaged Properties consist of owner-
occupied properties and investment properties. The Mortgaged Properties do not
include mobile homes which are not permanently affixed to the ground, commercial
properties or unimproved land. With respect to each Housing Loan, the "Cut-Off
Date Balance Outstanding" is the unpaid principal balance of such Housing Loan
as of the close of business on the Cut-Off Date. Housing Loans included in the
Trust Fund consist of variable and fixed rate loans originated by Westpac.
    
 
TRANSFER AND ASSIGNMENT OF HOUSING LOANS
 
    On the Closing Date, the Housing Loans purchased by the Trust will be those
specified in a Sale Notice from each of the Approved Sellers to the Issuer
Trustee. The Housing Loans to be sold by either the Seller Trustee or Westpac
from Westpac's general portfolio of residential Housing Loans have been in both
cases originated by Westpac in the ordinary course of its business. Each Housing
Loan may have some or all of the product features set out in "WESTPAC
RESIDENTIAL LOAN PROGRAM--Housing Loan Features" below. Generally each Housing
Loan is secured by a registered first ranking mortgage over the related
Mortgaged Property or, if the Housing Loan is not secured by a first ranking
mortgage, the Approved Seller will assign the Issuer Trustee all prior ranking
Registered Mortgages in relation to that Housing Loan. For more information on
the Housing Loans, see "WESTPAC RESIDENTIAL LOAN PROGRAM" below.
 
    On the Closing Date, the Approved Sellers will equitably assign the Housing
Loans, the Mortgages and the Related Securities (as defined herein) securing
those Housing Loans to the Issuer Trustee, pursuant to the Sale Notices, after
which the Issuer Trustee will be entitled to receive (with the assistance of TMC
in its capacity as servicer (the "Servicer") of the Housing Loans and custodian
of Related Documents (as defined herein), including the mortgage documents
relating to the Housing Loans) Collections on the Housing Loans. If a Title
Perfection Event occurs, the Issuer Trustee must, with the assistance of the
Trust Manager and Westpac, take certain actions to perfect its legal title in
the Housing Loans pursuant to an irrevocable power of attorney granted by
Westpac.
 
    "Related Security" in relation to a Housing Loan means: (a) any Relevant
Document for that Housing Loan, (b) any insurance policy or insurance proceeds
with respect to the Housing Loan, (c) any Mortgage Insurance Policy or Mortgage
Insurance Proceeds with respect to the Housing Loan, or (d) any other agreement
specified as "Related Security" for the Housing Loan in the Series Notice.
"Relevant Document" means, with respect to a Housing Loan, (a) the loan
agreement relating to that Housing Loan, (b) the mortgage document in relation
to such Housing Loan, (c) the certificate of title for the Mortgaged Property
secured by such mortgage, (d) any amendment or replacement of such documents and
any other document which is entered into by or executed in favor of the Approved
Seller or Issuer Trustee in connection with that Housing Loan after the Cut-Off
Date, or (e) any other document specified as a "Relevant Document" in the Series
Notice.
 
    An Approved Seller may in some instances assign to the Issuer Trustee a
Housing Loan secured by an "all moneys" Mortgage, which may also secure
financial indebtedness that has not been sold into the Mortgage Pool and is
instead retained by Westpac. The Issuer Trustee will hold the benefit of the
relevant Mortgage as bare trustee in relation to that other financial
indebtedness, although the Mortgage will secure the assigned Housing Loan in
priority to that other financial indebtedness.
 
                                       51
<PAGE>
REPRESENTATIONS AND WARRANTIES
 
    Westpac will make certain representations and warranties to the Issuer
Trustee in relation to the Housing Loans to be assigned by it to the Issuer
Trustee. Westpac also made representations and warranties in relation to the
Housing Loans to be sold by the Seller Trustee at the time those Housing Loans
were first transferred by Westpac to each relevant Seller Trustee, and the
benefit of those prior representations and warranties will be passed on to the
Issuer Trustee. The Servicer will make certain representations and warranties to
the Issuer Trustee in relation to the servicing of the Housing Loans to be sold
by the Seller Trustee to the Issuer Trustee. These representations and
warranties cover the period from when those Housing Loans were first transferred
by Westpac to other Seller Trusts until the Cut-Off Date. The Seller Trustee
will make certain limited representations and warranties in relation to the
Housing Loans to be assigned by it (e.g., as to title) to the Issuer Trustee.
 
    The Issuer Trustee has not investigated or made any inquiries regarding the
accuracy of these representations and warranties, and under the Master Trust
Deed is under no obligation to do so. The Issuer Trustee is entitled to rely
entirely upon the representations and warranties being correct (unless it has
actual notice of any event to the contrary). The rights of the Issuer Trustee in
the event that any representation or warranty is incorrect are described in
"--Breach of Representations and Warranties" below.

    If Westpac, the Trust Manager or the Issuer Trustee becomes aware within 120
days after the Closing Date that a representation or warranty from Westpac
relating to any Housing Loan or Mortgage is incorrect, it must notify the other
parties and the Rating Agencies within five Business Days of becoming so aware.
If such a notice in relation to a breach is given not later than five Business
Days before 120 days after the Closing Date and the breach is not waived or
remedied to the satisfaction of the Issuer Trustee within five Business Days
then, without any action being required by either party, Westpac shall be
 
                                       53
<PAGE>
obligated to repurchase the affected Housing Loan and Mortgage for an amount
equal to its Unpaid Balance.
 
    On payment of that amount the Issuer Trustee shall cease to have any
interest in the affected Housing Loan and Mortgage, and Westpac shall hold both
the legal and beneficial interest in such Housing Loan and Mortgage and be
entitled to all interest and fees that accrue in respect of them from (and
including) the date of repurchase.
 
    In any other case, the Issuer Trustee's rights in relation to a breach of a
representation or warranty shall give rise only to a claim for damages, limited
to an amount equal to the Unpaid Balance of that Housing Loan at the time
Westpac pays the damages.
 
HOUSING LOAN STATISTICS
 
   
    The Housing Loans will consist of 21,132 Housing Loans secured by Mortgages
on Mortgaged Properties located in the six states and two territories in
Australia, New South Wales ("NSW"), Victoria ("Vic"), Queensland ("QLD"), South
Australia ("SA"), Western Australia ("WA"), Tasmania ("TAS"), Northern Territory
("NT") and the Australian Capital Territory ("ACT"). The aggregate Cut-Off Date
Balances Outstanding of the Housing Loans (the "Cut-Off Date Pool Balance")
totaled approximately A$2,252,766,010. The Housing Loans bear interest at
variable and fixed rates. As of the Cut-Off Date, 74.70% of the Housing Loans by
Cut-Off Date Loan Balance are variable rate loans (the "Variable Rate Housing
Loans") and 25.30% of the Housing Loans by Cut-Off Date Loan Balance are fixed
rate loans (the "Fixed Rate Housing Loans"). The weighted average Mortgage Rate
for the Fixed Rate Housing Loans as of the Cut-Off Date was approximately 7.01%
per annum. The weighted average Mortgage Rate for the Variable Rate Housing
Loans as of the Cut-Off Date was approximately 6.42% per annum. The lowest
Cut-Off Date Balance Outstanding of any Housing Loan was approximately A$10,027
and the highest was approximately A$735,606. The average Cut-Off Date Balance
Outstanding of the Housing Loans was approximately A$106,604. The weighted
average original term to stated maturity of the Housing Loans was approximately
297.11 months. The weighted average remaining term to stated maturity of the
Housing Loans was approximately 288.41 months. As of the Cut-Off Date, the
weighted average number of months that have elapsed since origination of the
Housing Loans was approximately 8.7 months. The lowest and highest LVR of the
Housing Loans at Cut-Off Date were approximately 1.99% and 94.96%, respectively.
The weighted average LVR of the Housing Loans was approximately 70.00%.
    
 
   
    Housing Loans representing approximately 18.92% of the Cut-Off Date Pool
Balance are secured by Mortgaged Properties which are investment properties
(based solely upon statements made by the related Mortgagors at the time of
origination of the related Housing Loans).
    
 
    As of the Cut-Off Date, no Housing Loans were more than 30 days Delinquent.
 
    Set forth below is a description of certain additional characteristics with
respect to the Housing Loans held by the Trust and are not indicative of
Westpac's entire portfolio of housing loans. All percentages are approximate and
may not total 100% due to rounding.

POWERS
 
    Subject to the Master Trust Deed and the Series Notice, the Issuer Trustee
has all the rights, powers and discretion over and in respect of the Trust
Assets which it could exercise as if it were the beneficial owner of those
assets. These powers include the ability to invest in Authorized Investments, to
issue Notes and to enter into Support Facilities.
 
    The Master Trust Deed expressly permits the Issuer Trustee to appoint the
Servicer to retain custody of the mortgage documents for the Trust in accordance
with the Servicing Agreement, and for the Issuer Trustee to lodge documents with
the Servicer.
 
    Full details of the powers of the Issuer Trustee are set out in the Master
Trust Deed.
 
DUTIES
 
    The Issuer Trustee is required to act honestly and in good faith and to
exercise such diligence and prudence as a prudent person of business would
exercise in performing its express functions and in exercising its discretion
under the Master Trust Deed. It must keep each WST trust separate from the
others and do everything necessary to ensure it can comply with its obligations
under the Transaction Documents.
 
    In particular the Issuer Trustee has the duty to maintain a register of
Authorized Investments (other than the Housing Loans) and to ensure that the
Trust Manager keeps accounting records which correctly record and explain all
amounts paid and received by the Issuer Trustee.
 
    The Issuer Trustee is required to act continuously as trustee of the Trust
until the Trust is terminated as provided by the Master Trust Deed or the Issuer
Trustee has retired or been removed from office in the manner detailed below.
 
    Each Noteholder acknowledges that:
 
        (1) In the absence of fraud, negligence or breach of trust on its part
    or on the part of any of its officers, employees, agents or delegates, the
    Issuer Trustee shall not be liable personally in the event of failure to
    make payments on the Payment Date for payment to any Noteholder, any
    Beneficiary, the Trust Manager or any other person or for any loss howsoever
    caused in respect of any of the trusts or to any Noteholder, any
    Beneficiary, the Trust Manager or any other person.
 
                                       62
<PAGE>
        (2) The Issuer Trustee acts as trustee only in its capacity as trustee
    of the Trust and in no other capacity. Any liability arising under or in
    connection with a Transaction Document (including, without limitation, the
    Offered Notes) can be enforced against the Issuer Trustee only to the extent
    to which it can be satisfied out of property of the Trust out of which the
    Issuer Trustee is actually indemnified for the liability. This limitation of
    the Issuer Trustee's liability applies despite any other provision of the
    Transaction Documents and extends to all liabilities and obligations of the
    Issuer Trustee in any way connected with any representation, warranty,
    conduct, omission, agreement or transaction related to the Transaction
    Documents or the Trust. The limitation will not apply if there is a
    reduction in the Issuer Trustee's indemnification out of trust assets as a
    result of the Issuer Trustee's fraud, negligence or breach of trust.
 
        (3) The Issuer Trustee has no duty, and is under no obligation, to
    investigate whether a Trust Manager's Default, Servicer Transfer Event or
    Title Perfection Event has occurred in relation to the Trust other than
    where it has actual notice.
 
        (4) The Issuer Trustee is required to provide the notices referred to in
    the Master Trust Deed in respect of a determination of Adverse Effect only
    if it is actually aware of the facts giving rise to the Adverse Effect.
 
        (5) In making any such determination, the Issuer Trustee will seek and
    rely on advice given to it by its advisors in a manner contemplated by the
    Master Trust Deed.
 
    The Issuer Trustee is entitled to rely conclusively on, and is not required
to investigate the accuracy of:
 
        (i) the contents of a Sale Notice given to it by an Approved Seller;
 
        (ii) the contents of any report given to it by the Trust Manager or the
    Servicer;
 
       (iii) any calculations made by an Approved Seller, a Servicer or the
    Trust Manager including the calculation of payments due to, or to be charged
    against, the Noteholders, the Beneficiary or the Approved Seller on
    specified dates;
 
        (iv) the amount of, or allocation of, Collections; or
 
        (v) the contents of any certificate provided to the Issuer Trustee under
    the Master Trust Deed or any certificate given by the Trust Manager or the
    Servicer, unless the Issuer Trustee is actually aware to the contrary. The
    Issuer Trustee is not liable to any person in any manner whatsoever in
    respect of these matters.
 
DELEGATION
 
    In exercising its powers and performing its obligations and duties under the
Master Trust Deed, the Issuer Trustee may, with the approval of the Trust
Manager, delegate any or all of the duties, powers, discretion or other
functions of the Issuer Trustee under the Master Trust Deed or otherwise in
relation to the Trust, to a related company of the Issuer Trustee which is a
trustee company or trustee corporation for the purposes of any State or
Territory legislation governing the operation of trustee companies.
 
ISSUER TRUSTEE FEES AND EXPENSES
 
    The Issuer Trustee is entitled to a quarterly fee (the "Issuer Trustee Fee")
based on the average daily balance of the aggregate Housing Loan principal
during each Collection Period, payable in arrears on the relevant Payment Date.
 
    The Issuer Trustee is entitled to be reimbursed out of the assets of the
Trust for all expenses incurred in connection with the performance of its
obligations in respect of the Trust (other than general overhead costs and
expenses).
 
REMOVAL OF THE ISSUER TRUSTEE
 
    The Issuer Trustee is required to retire as trustee after a direction from
the Trust Manager in writing following an "Issuer Trustee's Default." An Issuer
Trustee's Default occurs if:
 
                                       63
<PAGE>
        (1) an Insolvency Event has occurred and is continuing in relation to
    the Issuer Trustee;
 
        (2) any action is taken or any event occurs by or in relation to the
    Issuer Trustee which causes the rating of any Notes to be downgraded;
 
        (3) the Issuer Trustee, or any employee, delegate, agent or officer of
    the Issuer Trustee, breaches any obligation or duty imposed on the Issuer
    Trustee under the Master Trust Deed or any other Transaction Document in
    relation to the Trust where the Trust Manager reasonably believes it may
    have an Adverse Effect and the Issuer Trustee fails or neglects after 30
    days' notice from the Trust Manager to remedy that breach;
 
        (4) the Issuer Trustee merges or consolidates with another entity
    without obtaining the consent of the Trust Manager and ensuring that the
    resulting merged or consolidated entity assumes the Issuer Trustee's
    obligations under the Transaction Documents; or
 
        (5) there is a change in effective control of the Issuer Trustee from
    that subsisting as at the date of the Master Trust Deed unless approved by
    the Trust Manager.
 
    Where the Issuer Trustee is removed because of its default, it shall bear
the costs of such removal. The Issuer Trustee will indemnify the Trust Manager
and the Trust for such costs.
 
    On the removal of the Issuer Trustee, the Trust Manager, subject to giving
prior notice to the Rating Agencies, shall be entitled to appoint in writing
some other statutory trustee to be the Issuer Trustee under the Master Trust
Deed provided that appointment will not in the reasonable opinion of the Trust
Manager materially prejudice the interests of Noteholders. Until the appointment
is completed the Trust Manager shall act as Issuer Trustee and will be entitled
to the trustee's fee for the period it so acts as Issuer Trustee.
 
VOLUNTARY RETIREMENT OF THE ISSUER TRUSTEE
 
    The Issuer Trustee may resign on giving to the Trust Manager (with a copy to
the Rating Agencies) not less than 3 months' notice in writing (or such other
period as the Trust Manager and the Issuer Trustee may agree) of its intention
to do so.
 
    Before retirement, the Issuer Trustee must appoint a successor trustee who
is approved by the Trust Manager, or who may be the Trust Manager, and whose
appointment will not materially prejudice the interests of Noteholders. If a
successor trustee has not been appointed by the end of the 3 months' notice
period the Trust Manager shall act as trustee until a successor trustee is
appointed.
 
LIMITATION OF ISSUER TRUSTEE'S LIABILITY
 
    In the absence of fraud, negligence or breach of trust on its part, or on
the part of any of its officers, employees, agents or delegates, the Issuer
Trustee shall not be liable personally in the event of failure to pay moneys on
the Payment Date for payment to any Noteholder, any Beneficiary, the Trust
Manager or any other person or for any loss howsoever caused in respect of any
of the trusts or to any Noteholder, any Beneficiary, the Trust Manager or any
other person.
 
    The Issuer Trustee acts as trustee only in its capacity as trustee of the
Trust and in no other capacity. A Noteholder cannot sue the Issuer Trustee
personally except in the case of fraud, negligence or breach of trust on the
part of the Issuer Trustee. Any liability arising under or in connection with a
Transaction Document (including, without limitation, any Offered Note) can be
enforced against the Issuer Trustee only to the extent to which it can be
satisfied out of property of the Trust out of which the Issuer Trustee is
actually indemnified for the liability. This limitation of the Issuer Trustee's
liability applies despite any other provision of the Transaction Documents and
extends to all liabilities and obligations of the Issuer Trustee in any way
connected with any representation, warranty, conduct, omission, agreement or
transaction related to the Transaction Documents or the Trust. The limitation
will not apply to the extent that there is a reduction in the Issuer Trustee's
indemnification out of trust assets as a result of the Issuer Trustee's fraud,
negligence or breach of trust.
 
    The Issuer Trustee is also indemnified out of the Trust assets against
certain payments which it may be liable to make under the Consumer Credit
Legislation. The Approved Sellers have also indemnified the
 
                                       64
<PAGE>
Issuer Trustee in relation to such payments and the Issuer Trustee is required
to first call on the indemnity from the Approved Sellers.
 
    The Master Trust Deed also contains other provisions which regulate the
Issuer Trustee's liability to Noteholders, other creditors and any Beneficiary.
The Issuer Trustee is not liable to any person for any losses, costs,
liabilities or expenses arising out of the exercise or non exercise of its
discretion (or by the Trust Manager of its discretion) or for any instructions
or directions given to it by the Trust Manager, the Servicer or either of the
Approved Sellers except to the extent that it is caused by the Issuer Trustee's
or its officer's, employee's, agent's or delegate's fraud, negligence or breach
of trust. The Issuer Trustee is also not liable for any Trust Manager's Default,
Servicer Transfer Event or Title Perfection Event. The Issuer Trustee is not
liable for any act, omission or default of the Servicer in relation to its
custodian duties or its obligations under the Servicing Agreement.
 
RIGHTS OF INDEMNITY OF ISSUER TRUSTEE
 
    Except where the Issuer Trustee fails to exercise due care or is otherwise
disentitled (including, without limitation, because of fraud, negligence or
breach of trust on its part) the Issuer Trustee will be indemnified out of the
Trust Assets against all losses and liabilities incurred by the Issuer Trustee
in properly performing any of its duties or exercising any of its powers under
the Transaction Documents in relation to the Trust.
 
LIMITATION OF SELLER TRUSTEE'S LIABILITY AND RIGHTS OF INDEMNITY
 
    In the absence of fraud, negligence or breach of trust on its part, the
Seller Trustee shall not be liable personally in the event of failure to pay
moneys on the Payment Date for payment to any Noteholder, any Beneficiary, the
Trust Manager or any other person or for any loss howsoever caused in respect of
any of the trusts or to any Noteholder, any Beneficiary, the Trust Manager or
any other person.
 
    The Seller Trustee acts as Seller Trustee only in its capacity as seller
trustee of the relevant Seller Trust and in no other capacity. A liability
arising under or in connection with a Transaction Document can be enforced
against the Seller Trustee only to the extent to which it can be satisfied out
of property of the relevant Seller Trust out of which the Seller Trustee is
actually indemnified for the liability. This limitation of the Seller Trustee's
liability applies despite any other provision of the Transaction Documents and
extends to all liabilities and obligations of the Seller Trustee in any way
connected with any representation, warranty, conduct, omission, agreement or
transaction related to the Transaction Documents, the Trust or the relevant
Seller Trust. The limitation will not apply to the extent that there is a
reduction in the Seller Trustee's indemnification out of trust assets or the
relevant Seller Trust as a result of the Seller Trustee's fraud, negligence or
willful default.
 
    The Seller Trustee is also indemnified out of the assets of the relevant
Seller Trust against certain payments which it may be liable to make under the
Consumer Credit Legislation. Westpac has also indemnified the Seller Trustee in
relation to such payments and the Seller Trustee is required to first call on
the indemnity from Westpac.
 
RIGHTS OF INDEMNITY OF SELLER TRUSTEE
 
    Except where the Seller Trustee fails to exercise due care or is otherwise
disentitled (including, without limitation, because of fraud, negligence or
breach of trust on its part) the Seller Trustee will be indemnified out of each
relevant Seller Trust against all losses and liabilities incurred by the Seller
Trustee in properly performing any of its duties or exercising any of its powers
under the Transaction Documents in relation to the Trust or any Seller Trust.
 
    The Seller Trustee has not been involved in the preparation of, and does not
accept responsibility for, this Prospectus.

                        ORIGINATOR OF THE HOUSING LOANS
 
    Westpac Banking Corporation ("Westpac"), Level 4, 60 Martin Place, Sydney,
NSW 2000, Australia, was the first bank to be established in Australia. Westpac
was founded in 1817 and was incorporated in 1850 as Bank of New South Wales by
an Act of the New South Wales Parliament. In 1982, the Bank acquired The
Commercial Bank of Australia Limited, and the Bank changed its name to Westpac
Banking Corporation.
 
    Today Westpac is one of the four major commercial banks in Australia and is
the largest commercial bank in New Zealand. The Westpac Group undertakes a wide
range of banking and financial activities including commercial and investment
banking, personal and small business banking, retail and wholesale funds
management, financial services and finance company operations.
 
    The Australian banking activities of Westpac come under the supervision of
the Reserve Bank of Australia.
 
YEAR 2000
 
    The origin of the Year 2000 "millennium bug" problem lies in the way
information in computer systems relating to calendar dates has been stored.
Computer systems, built when data storage was expensive, saved only the last two
digits of a year for date calculations in order to reduce data storage
requirements. These systems are therefore unable to differentiate, for example,
between the years 1900 and 2000. This inability to differentiate between the
different centuries could result in discrepancies such as erroneous interest
rate calculations and inaccurate statement reporting.
 
    In recognition of the seriousness of the problem, work within the Westpac
Group began in 1996 when a Year 2000 project was initiated. The conversion plan
for making the Westpac Group's applications Year 2000 compliant is estimated to
cost approximately A$60 million, of which A$24 million has been spent as of the
end of March 1998. To the maximum extent possible, the project will utilize
existing Westpac Group resources. The objective is that all systems will be
materially Year 2000 compliant by December 31, 1998, to allow adequate time for
testing and to minimize resource requirements in later years. Management of
Westpac currently estimates that the balance of the Year 2000 project conversion
will be completed by December 1998.
 
                                  THE SERVICER
 
GENERAL
 
    In 1996, Westpac established a wholly owned subsidiary, The Mortgage Company
Pty Limited ("TMC") of Level 6, 228 Pitt Street, Sydney 2000, Australia, to
provide mortgage servicing capability to both Westpac and to third parties. TMC
operates from a new servicing center in Adelaide, known as the Mortgage
Processing Centre ("MPC"). The MPC employs over 1,000 staff, and processes
approximately 1400 new applications per day.
 
                                       66
<PAGE>
    The MPC performs the following functions for Westpac: application
processing, telephone support, pre-settlement, settlement, post-settlement,
servicing and account maintenance, collections and enforcement and document
custody.
 
SERVICING OF HOUSING LOANS
 
    Under the Servicing Agreement, the ongoing servicing of the Housing Loans
will be performed by TMC, as the Servicer at the MPC. Servicing procedures
include responding to customer inquiries, managing and servicing the features
and facilities available under the Housing Loans and the management of
delinquent Housing Loans. The servicing functions performed by the MPC support,
and are supported by, the activities of Westpac's branches, telemarketing and
telebanking centers. In addition, the MPC services housing loans for third
parties.
 
    The Servicer is contractually obligated to administer the Housing Loans: (i)
in accordance with the Servicing Agreement; (ii) in accordance with Westpac's
policies, which are under regular review and may change from time to time in
accordance with business judgment and changes to legislation and guidelines
established by relevant regulatory bodies; and (iii) to the extent not covered
by paragraphs (i) and (ii), by exercising the degree of diligence and care
expected of an appropriately qualified Servicer of the relevant Housing Loans.
See "DESCRIPTION OF THE SERVICING AGREEMENT."
 
DOCUMENT CUSTODY
 
    The Servicer is responsible for custody of the mortgage title documents on
behalf of the Issuer Trustee and has custody of the Relevant Documents in
accordance with the Servicing Agreement. See "DESCRIPTION OF THE SERVICING
AGREEMENT--Document Custody."
 
COLLECTION AND ENFORCEMENT PROCEDURES
 
    Borrowers must make the minimum payment due under the terms and conditions
of the Housing Loan on or before the due date for that installment under the
relevant loan documents. Payments are credited to the Housing Loan on the day of
receipt. Interest is calculated daily and can be charged monthly or when a
payment is made. Any payments not received by the due date will produce a
compounding interest effect.
 
    A housing loan is considered delinquent ("Delinquent") whenever the minimum
installment amount is not met. The collections system inspects all accounts
which are delinquent and records those housing loans for action and follow-up.
Borrowers are notified by telephone and/or by mail when their housing loan
becomes Delinquent. Housing loans are allocated to collections officers who take
action depending on the delinquency history of the Borrower, equity in the
property and the ability of the Borrower to meet future installments. Where a
housing loan that is Delinquent is subject to a Mortgage Insurance Policy, the
relevant Mortgage Insurer is notified of the housing loan's progress and all
follow-up actions are taken by Westpac and the Servicer.
 
    When a housing loan is 10 days delinquent, it is identified in the Mortgage
Servicing System and transferred to the collection system of the MPC. Generally,
once a housing loan is 15 days delinquent, a computer generated letter is sent
to the borrower advising of the arrears and requesting that the borrower make
payments so that his account is current. When the account reaches between 23 and
29 days delinquent, the borrower will be contacted by telephone or, if not
contacted, a second letter will be sent by day 30. Between day 30 and day 45
generally the borrower will again be contacted by telephone. When the account
reaches between 45 and 58 days delinquent, a third letter is generally issued
which requests that the account be made current within 15 days of the date
thereof. Generally, after an account is between 62 and 73 days overdue, a demand
for full arrears is issued. Between 97 and 110 days, if the account continues to
be in arrears, a demand notice will generally be issued to the borrower and the
process of contract enforcement and loss recovery begins. The time periods
specified herein assume the borrower has either taken no action or has not
honored any commitments made in relation to the arrears.
 
                                       67
<PAGE>
    After a default by a borrower a mortgagee can exercise its power of sale of
the mortgaged property. To exercise this power, a mortgagee must comply with the
statutory restrictions of the relevant state or territory as to notice
requirements (see "CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS - Enforcement of
Housing Loans"). The length of time between the decision to exercise its power
of sale and final completion of the sale will be dependent on factors outside
the control of the Servicer, such as whether the relevant mortgagor contests the
sale and the market conditions at the time.
 
    Under some Housing Loans which are subject to a variable rate of interest, a
Borrower may prepay amounts which are additional to their minimum payments to
build up a buffer of funds, which is the difference between the total amount
paid by them and the total of the minimum payments required to have been made by
them. If the Borrower subsequently fails to make some or all of a minimum
payment, the collection system will apply the amount of that buffer of funds
against that missed payment. The relevant Housing Loan will not be considered to
be Delinquent until the total amount of missed payments exceeds the "credit
buffer."
 
    Under a Housing Loan which is charged a variable rate of interest, a
Borrower who is on maternity or paternity leave and who meets specific
eligibility criteria may apply to reduce their monthly home loan repayment by up
to 50% for a maximum of six months. During the reduced repayments period, if the
payment is not sufficient to meet the interest due, the unpaid interest payment
will capitalize on the loan balance and the loan may negatively amortize.
Repayments are adjusted at the end of the parental leave period to ensure that
the loan will be repaid within its original contracted maturity.
 
    The collection and enforcement procedures may change from time to time in
accordance with business judgment and changes to legislation and guidelines
established by the relevant regulatory bodies.
 
DELINQUENCIES AND MORTGAGEE IN POSSESSION WITH RESPECT TO THE SECURITIZED
  PORTFOLIOS
 
    The following tables set forth delinquency and MIP information for each of
the Securitized Portfolios (as defined herein) serviced by the Servicer in its
capacity as Servicer of securitized loans as of December 1997 and March 1998.
"Mortgagee in Possession" or "MIP" means a mortgagee in possession of the
related Mortgaged Property who, following an enforcement of the relevant
mortgage, is able to deal with the Mortgaged Property without becoming the
absolute owner of the Mortgaged Property. The portfolios of securitized housing
loans (the "Securitized Portfolios") consist of the Housing Loans relating to
the Series 1997-2 WST Trust, Series 1997-3 WST Trust and the Series 1997-4E WST
Trust. The indicated periods of delinquency are based on the number of days past
due on a contractual basis. Similar information with respect to the Series
1998-1G WST Trust will be contained in the reports presented through Reuters for
access by investors. Such reports will be compiled using the same methodology as
that used to compile the information contained in the table below.

    As of the date hereof, there have been no gains or losses with respect to
the Securitized Portfolios. Accordingly, no gain/loss tables are presented
herein.
 
    It is unlikely that the delinquency experience of the Housing Loans
comprising the Series 1998-1G WST Trust will correspond to the delinquency
experience of the Securitized Portfolios set forth in the foregoing tables. The
statistics shown above represent the delinquency experience for the Securitized
Portfolios only for the periods presented, whereas the aggregate delinquency
experience on the Housing Loans comprising the Securitized Portfolios will
depend on the results obtained over the life of the Securitized Portfolios.
There can be no assurance that the Housing Loans comprising the Series 1998-1G
WST Trust will perform consistently with the delinquency or foreclosure
experience described herein. It should be noted that if the residential real
estate market in Australia should experience an overall decline in property
values, the actual rates of delinquencies and foreclosures could be higher than
those previously experienced by the Servicer with respect to the Securitized
Portfolios. In addition, adverse economic conditions may affect the timely
payment by Borrowers of scheduled payments of principal and interest on the
Housing Loans and, accordingly, the actual rates of delinquencies and
foreclosures with respect to the Series 1998-1G WST Trust.

DUTIES AND ROLE OF THE TRUST MANAGER
 
POWERS
 
    The Trust Manager will carry out and perform the duties and obligations
contained in the Master Trust Deed and will have full and complete powers of
management of the Trust, including without limitation in relation to the conduct
of the day to day operation of the Trust and the administration and servicing of
the assets (which are not serviced by the Servicer), borrowings and other
liabilities of the Trusts. The Issuer Trustee has no duty to supervise the Trust
Manager in the performance of its functions and duties or the exercise of its
discretion.
 
    The Trust Manager has the absolute discretion to recommend Authorized
Investments to the Issuer Trustee and direct the Issuer Trustee in relation to
those Authorized Investments. The Issuer Trustee's role is to give effect to all
such recommendations or directions.
 
DELEGATION
 
    The Trust Manager may in carrying out and performing its duties and
obligations contained in the Master Trust Deed delegate to Westpac, or any of
the Trust Manager's or Westpac's officers and employees, all acts, matters and
things (whether or not requiring or involving the Trust Manager's judgment or
discretion), or appoint any person to be its attorney, agent, delegate or
sub-contractor for such purposes and with such powers as the Trust Manager
thinks fit.
 
TRUST MANAGER'S FEES AND EXPENSES
 
    The Trust Manager is entitled to a quarterly fee (the "Trust Manager Fee")
on the average daily balance of the aggregate principal balance of Housing Loans
outstanding during the Collection Period payable in arrears on the relevant
Payment Date.
 
    The Trust Manager is entitled to be reimbursed out of the Trust Assets for
all expenses incurred in connection with the performance of its obligations in
respect of the Trust (other than general overhead costs and expenses).
 
REMOVAL OF THE TRUST MANAGER
 
    The Trust Manager shall retire as trust manager if so directed by the Issuer
Trustee in writing following a Trust Manager's Default. A "Trust Manager's
Default" occurs if:
 
        (1) the Trust Manager fails to make any payment required by it within
    the time period specified in a Transaction Document, and that failure is not
    remedied within 10 Business Days of receipt from the Issuer Trustee of
    notice of that failure;
 
        (2) an Insolvency Event has occurred and is continuing in relation to
    the Trust Manager;
 
        (3) the Trust Manager breaches any obligation or duty imposed on the
    Trust Manager under the Master Trust Deed, any other Transaction Document or
    any other deed, agreement or arrangement entered into by the Trust Manager
    under the Master Trust Deed in relation to the Trust, the Issuer Trustee
    reasonably believes that such breach has an Adverse Effect and the breach is
    not remedied within 30 days' notice being given by the Issuer Trustee
    (except in the case of reliance by the Trust Manager on the information
    provided by, or action taken by, the Servicer, or if the Trust Manager has
    not received information from the Servicer which the Trust Manager requires
    to comply with the obligation or duty); or
 
        (4) a representation, warranty or statement by or on behalf of the Trust
    Manager in a Transaction Document or a document provided under or in
    connection with a Transaction Document is not true in a material respect or
    is misleading when repeated and is not remedied to the Issuer Trustee's
 
                                       71
<PAGE>
    reasonable satisfaction within 90 days after notice from the Issuer Trustee
    where (as determined by the Issuer Trustee) it has an Adverse Effect.
 
    The costs of removal of the Trust Manager after a Trust Manager's Default
shall be borne by the Trust Manager. The Trust Manager has agreed to indemnify
the Issuer Trustee and the Trust for those costs.
 
    On retirement or removal of the Trust Manager, the Issuer Trustee may
appoint another trust manager, provided the appointment will not materially
prejudice the interests of Noteholders. Until a replacement Trust Manager is
appointed, the Trust Manager must continue as Trust Manager. If a replacement
Trust Manager is not appointed within 120 days of the Issuer Trustee electing to
appoint a new Trust Manager, the Issuer Trustee will be the new Trust Manager.
 
VOLUNTARY RETIREMENT OF THE TRUST MANAGER
 
    The Trust Manager may resign on giving to the Issuer Trustee (with a copy to
the Rating Agencies) not less than 3 months' notice in writing (or such other
period as the Trust Manager and the Issuer Trustee may agree) of its intention
to do so.
 
    Before retirement, the Trust Manager must appoint a successor Trust Manager
who is approved by the Issuer Trustee, or who may be the Issuer Trustee, and
whose appointment will not materially prejudice the interests of Noteholders. If
a successor Trust Manager has not been appointed by the end of the 3 months'
notice period the Issuer Trustee shall act as Trust Manager until a successor
trust manager is appointed.
 
LIMITATION OF TRUST MANAGER'S LIABILITY
 
    The principal limitations on the Trust Manager's liability are set out in
full in the Master Trust Deed. These include the following limitations:
 
        (1) in the absence of fraud, negligence or wilful default on its part or
    on the part of any of its officers, employees, agents or delegates, the
    Trust Manager shall not be liable personally in the event of failure to pay
    moneys on the due date for payment to any Noteholder, any Beneficiary, the
    Issuer Trustee or any other person or for any loss howsoever caused in
    respect of any of the Trusts or to any Noteholder, any Beneficiary, the
    Issuer Trustee or other person;
 
        (2) the Trust Manager will not be personally liable to indemnify the
    Issuer Trustee or make any payments to any other person in relation to the
    Trust except that there will be no limit on the Trust Manager's liability
    for any fraud, negligence or wilful default by it in its capacity as the
    Trust Manager of the Trust;
 
        (3) the Trust Manager will be indemnified out of the Trust in respect of
    any liability, cost or expense properly incurred by it in its capacity as
    Trust Manager of the Trust or so incurred by any of its delegates,
    sub-delegates or agents; and
 
        (4) subject to the Master Trust Deed, the Trust Manager is not
    responsible for any act, omission, misconduct, mistake, oversight, error of
    judgment, forgetfulness or want of prudence on the part of the Issuer
    Trustee, the Servicer or any agent appointed by the Issuer Trustee or the
    Trust Manager or on whom the Issuer Trustee or the Trust Manager is entitled
    to rely under this deed (other than a related company), attorney, banker,
    receiver, barrister, solicitor, agent or other person acting as agent or
    adviser to the Issuer Trustee or the Trust Manager.

                        WESTPAC RESIDENTIAL LOAN PROGRAM
 
ORIGINATION OF HOUSING LOANS
 
    The following are the primary sources for the origination of housing loans
for Westpac: the Westpac branch network, mobile finance managers, accredited
brokers and national telemarketing centers. Inquiries are also often generated
by advertising and direct mail campaigns.
 
    The origination process for housing loans is carried out initially within
the appropriate Westpac branch or broker office. The origination process for all
housing loans is completed within the MPC.
 
UNDERWRITING OF HOUSING LOANS
 
    The following is a description of the underwriting processes employed by
Westpac in evaluating whether to fund a particular housing loan. When an
application is received, it is processed in accordance with Westpac's credit
policy and procedures. Credit assessment is undertaken initially using Westpac's
centrally controlled credit scoring system. The scoring system is based on
proprietary information, such as Westpac's own historical credit underwriting
experience and product policy rules. The process also includes a reference from
the Credit Reference Association of Australia. Housing loans passing through the
credit scoring system will either be approved, declined or referred to a credit
specialist. Westpac's criteria do not seek to segment borrowers who pass the
credit scoring system into groups of differing credit quality. All borrowers
must meet Westpac's standard underwriting criteria and therefore are not charged
different rates of interest based on their credit quality. Where a housing loan
is referred to a credit specialist, it is generally because the application is
more complex (for example, where the Housing Loan principal is over A$750,000 or
because the application is from a self-employed individual). An assessment is
carried out by either credit officers within the Credit Unit at the MPC or, in
some cases, by State based Credit Centers, in accordance with designated Westpac
credit policy and their credit approval limits. Each housing loan is considered
on its merits within Westpac's credit policy and procedures.
 
    Central to the approval process is the verification of the information
provided by the applicant(s), valuation of the proposed security property and
confirmation of the ability of the applicant to make payments on the housing
loan. The verification process involves conducting an independent check as to
the accuracy and correctness of the information provided by the potential
Borrower, particularly the documentation provided by the prospective borrower
and the employment and income details of the prospective borrower. Verification
relating to the income of self-employed applicants involves checking annual
accounts and other financial information.
 
    All applicants are required to have a minimum monthly income net of taxes in
excess of all monthly expenditures (including the housing loan being applied
for) with consideration given to likely increases in future interest rates.
 
    Westpac policy requires substantiation of the property value either by
contract of sale or valuation by a registered panel valuer. A valuation of the
security property is required where lender's mortgage insurance is required,
where the Housing Loan Principal is greater than A$250,000 or the LVR is greater
than 80% (although the LVR and Housing Loan Principal may be lower if the
relevant Mortgaged Property is in a particular geographic area). Valuations must
be performed by registered valuers who are members of the Australian Institute
of Valuers and Land Economists. In some remote centers, assessment of the
security value is undertaken by the local branch manager. In addition, housing
loans may be secured by more than one property and in such cases the combined
values of all relevant security properties is considered.
 
    Following pre-approval of a housing loan, a terms and conditions letter is
sent to the applicant from the MPC. When Westpac has verified details relating
to the Housing Loan to its satisfaction and acceptance of the loan offer is
received, the housing loan can proceed through to settlement and
 
                                       73
<PAGE>
disbursement. Once all documentation is completed to Westpac's satisfaction and
settlement or disbursement has occurred, the security documents are stamped and
registered. It is a condition of Westpac's standard mortgage documentation that
the mortgagor must maintain full replacement value property insurance at all
times. Westpac currently maintains a blanket insurance policy with Cigna
Insurance Asia Pacific Pty Limited which covers loss from a mortgage default
which follows from physical loss, destruction or damage to a Mortgaged Property
which is not otherwise covered by adequate property insurance.
 
    Approval policies are under regular review and may change from time to time
in accordance with business judgment and changes to legislation and guidelines
established by the relevant regulatory bodies.
 
SERVICING OF HOUSING LOANS
 
    Under the Servicing Agreement, the ongoing servicing of the Housing Loans
will be performed by the Servicer. See "THE SERVICER" and "DESCRIPTION OF THE
SERVICING AGREEMENT."
 
HOUSING LOAN PRODUCTS
 
    Westpac originates loans for both owner-occupied and investment housing. The
products within the housing loan portfolio are the following: Premium Option
Home Loan, Premium Option Home Loan with 1 Year Guaranteed Rate, Special Offer
Fixed Option Home Loan, First Option Home Loan, Fixed Options Home Loan,
Variable Rate Investment Property Loan, Fixed Rate Investment Property Loan,
First Option Investment Property Loan and Special Fixed Rate Investment Property
Loan or any other similar loan product, however named, with some or all the
features referred to under "Housing Loan Features." During the term of any
Housing Loan, Westpac may from time to time or at the request of the related
Borrower change any of the features of such Housing Loans.
 
    The following provides a general description of some of the Housing Loan
products detailed above. The Housing Loans comprising the Mortgage Pool must
satisfy certain eligibility criteria as specified under "THE TRUST
FUND--Representations and Warranties."
 
OWNER OCCUPIED HOME LOANS
 
    First Option Home Loans:  These loans are low variable rate owner-occupied
home loans for borrowers motivated by price. The product was developed to
compete with products offered by non-bank originators. Additional loan features
(as described below) can be activated on request by the borrower for a fee. The
current maximum term for this product is 25 years, although it may be changed to
30 years in the future.
 
    Premium Option Home Loans:  These loans are variable rate owner-occupied
home loans. These loans have a maximum term to maturity of 30 years and a higher
rate of interest than the First Option Home Loan and as a result, borrowers are
allowed access to the various loan features at no or reduced additional cost.
 
    Premium Option Home Loans with 1 Year Guaranteed Rate:  These loans have an
introductory discounted fixed rate for 12 months and then convert to a Premium
Option Home Loan. Apart from the introductory fixed rate period, the loan has
the same features as the Premium Option Home Loan.
 
    Special Offer Fixed Option Home Loans:  These loans have a fixed rate period
of one or two years that converts to a Premium Option Home Loan. Apart from the
fixed rate period, the loan has the same features as the Premium Option Home
Loan. In 1996, this product was replaced by the Premium Option Home Loan with 1
Year Guaranteed Rate product described above.
 
    Fixed Options Home Loans:  These loans are fixed rate owner-occupied home
loans. Loan terms are to a maximum of 30 years with a maximum fixed rate term of
10 years. On maturity of the fixed rate term,
 
                                       74
<PAGE>
the loan converts to the Premium Option Home Loan unless the borrower requests a
further fixed rate period. Certain product features (E.G., redraw) are not
available during the fixed rate period.
 
INVESTMENT PROPERTY LOANS
 
    An investment property loan is a loan which assists with the purchase or
refinancing of residential property for investment purposes such as rental
income or capital gain. The primary security for the loan is a registered first
party first ranking mortgage over residential property.
 
    Investment property loans can be either fixed rate or variable rate loans
with a maximum term of 25 years. The loans may provide for interest only
payments for a maximum term of 5 years and then must convert to required payment
of principal and interest. Loans may have fixed rate terms for up to a maximum
of 10 years which will convert at such time to a variable rate unless the
borrower requests another fixed rate term.
 
    The First Option Investment Property Loan is a low variable rate loan which
is similar to the First Option Home Loan and the Variable Investment Property
Loan is similar to the Premium Option Home Loan, the major difference being the
loan purpose.
 
HOUSING LOAN FEATURES
 
GENERAL
 
    Housing Loans originated by Westpac may have some or all of the features
described below. In addition, during the term of any Housing Loan, Westpac may
change any of the features of such Housing Loan from time to time at the request
of the related Borrower. For the risks associated with the change in features,
see "RISK FACTORS--Ability to Change Housing Loan Features May Result in Changes
to the Mortgage Pool and Higher Principal Prepayment on the Offered Notes."
 
SUBSTITUTION OF SECURITY
 
    A Borrower may apply to substitute a new Mortgage over a residential
property for an existing Mortgage, to add a further Mortgage as security for a
Housing Loan or to release a security property under a Mortgage. Provided that
the application meets certain credit criteria, the Mortgage which secures a loan
may be portable and may be discharged without full repayment of the Housing Loan
provided another acceptable Mortgage is substituted in its place.
 
    Where the substitute property meets the Eligibility Criteria and is
acceptable to the relevant Mortgage Insurer, and settlement on the substitute
property can occur simultaneously with the discharge of the current property,
the Housing Loan will remain in the Mortgage Pool. Where the substitute property
does not meet the Eligibility Criteria or is not acceptable to the Mortgage
Insurer, or the settlement does not occur simultaneously with discharge, the
Housing Loan will be transferred out of the Mortgage Pool for a corresponding
cash payment in the amount of the Unpaid Balance.
 
REDRAW
 
    Certain Housing Loans in the Mortgage Pool which are charged a variable rate
of interest have the benefit of a redraw facility which allows the Borrower to
draw on repayments made in excess of scheduled repayments (a "Redraw").
Borrowers may request a redraw at any time. In certain circumstances, Westpac
has a contractual obligation under the loan document to provide the redraw
should the Borrower be entitled to a redraw because of prepayments and if the
Housing Loan is not delinquent.
 
    A Redraw will not result in the Housing Loan being removed from the Mortgage
Pool.
 
    See "DESCRIPTION OF THE OFFERED NOTES--Description of the Redraw Facility,
Redraw Funding Securities and RFS Class A Notes."
 
                                       75
<PAGE>
REPAYMENT HOLIDAY
 
    The terms of the Mortgage securing a Housing Loan which is charged a
variable rate of interest may provide for a "payment holiday." A payment holiday
can occur where the Borrower has prepaid amounts of principal, creating a buffer
of funds between the current principal balance and the amortization scheduled
balance. In such a case, the Borrower may cease to make payments until the
outstanding balance of the Housing Loan plus unpaid interest equals the balance
of the theoretical amortization schedule. Where the Housing Loan allows for a
"payment holiday", the Housing Loan payment will be taken from the buffer of
funds between the current principal balance and the amortization scheduled
balance at that payment date. If a buffer of funds is available, the system will
recognize this as an installment received. Housing Loans are not considered
Delinquent during a payment holiday and remain in the Mortgage Pool.
 
EARLY REPAYMENT
 
    Early repayment and partial prepayment of any Housing Loan is permitted
while such Housing Loan is subject to a variable rate of interest. Housing Loans
which are charged a fixed rate of interest, if repaid within their fixed rate
term, may be subject to an economic break cost or benefit in accordance with the
terms of the Housing Loan. For Housing Loans not regulated by the Consumer
Credit Legislation, an early termination fee may be payable.
 
TOP UP
 
    The loan agreement and/or Mortgage relating to a Housing Loan may allow for
the relevant Borrower to request from Westpac additional funds such that the
resulting principal balance will exceed the amortization scheduled balance at
that time. These are "top ups." Top ups will only be provided by Westpac in
accordance with its then current underwriting and credit policies. Any Housing
Loan for which Westpac provides a top up will be removed from the Mortgage Pool.
 
PARENTAL LEAVE
 
    Under a Housing Loan which is charged a variable rate of interest, any
Borrower who is on maternity or paternity leave and who meets specific
eligibility criteria may apply to reduce the related monthly home loan repayment
by up to 50% of such payment amount for a maximum of six months. During the
reduced repayment period, if the payment is not sufficient to meet the interest
due, the unpaid interest payment will capitalize on the loan balance and the
loan may negatively amortize. Scheduled repayments are adjusted at the end of
the parental leave period to ensure that the loan will be repaid within its
original contracted maturity.
 
INTEREST RATE SWITCHING
 
    The interest rate charged on Housing Loans may be either fixed rate or
variable rate. Fixed rate loans will automatically convert to variable rate at
the end of the fixed rate period (as specified in the related loan agreement)
unless the relevant Borrower elects another fixed rate period. Some loans have
an introductory fixed rate of interest which converts to a variable rate of
interest at the end of such introductory period. Some loans allow the Borrower
the option to convert from a variable rate to a fixed rate (or vice versa).
 
ACCOUNT MANAGEMENT FACILITY
 
    A Borrower may elect to have his/her regular salary paid in full or part
into their Housing Loan account. If this amount exceeds the amortized scheduled
balance at that time, surplus funds are created therein that may be redrawn.
This feature will allow the customer in the aggregate up to fifteen automatic
 
                                       76
<PAGE>
disbursements in each payment cycle against these surplus funds to other
accounts. These disbursements will be treated as Redraws.
 
PAYMENT TYPE
 
    On the Cut-Off Date, the payment types under the Housing Loans will be
interest only or principal, interest and fees ("P & I"). Interest only periods
can be for terms of one to five years. At the end of any interest only period,
the payment type under the relevant Housing Loan will convert to P & I payments
such that the scheduled payments will result in the Housing Loan being repaid on
an amortizing schedule within the contractual term of the Housing Loan.
 
SWITCHING TO AN INVESTMENT OR OWNER-OCCUPIED LOAN
 
    The Borrower may elect to switch the purpose of a Housing Loan from
owner/occupied property finance to investment property finance or vice versa.
Any such switch will not require the relevant Housing Loan to be removed from
the Mortgage Pool. The Borrower is required to notify Westpac of such switch and
the Mortgage Rate with respect to such Housing Loan may be changed accordingly.
 
CAPITALIZED FEES
 
    Westpac may offer Borrowers the ability to choose certain product features
without paying an up-front fee. Instead, the fee may be capitalized under the
Housing Loan and would constitute part of the principal to be amortized over the
life of the Housing Loan.
 
COMBINATION HOUSING LOANS
 
    A Borrower may split his/her Housing Loan into different portions which may
(among other things) be subject to different interest rate options. This could
occur, for example, where a Borrower elects to have one part of their Housing
Loan at a fixed rate and the other at a variable rate. Each loan is effectively
a separate loan which operates independently of the other loans in the combined
product and is governed by its own policy and procedures.
 
    If a Housing Loan is "split" into more than one loan, any newly created
loans will not form part of the pool. In the event that the original loan is
retained (potentially at a reduced balance) in certain circumstances (E.G., it
satisfies all Eligibility Criteria and does not have any feature that would
require it to be removed from the pool) it will remain in the pool.
 
ADDITIONAL FEATURES
 
    Westpac may, in relation to a Housing Loan in the Mortgage Pool, from time
to time seek to offer additional features which are not referred to above.
Before doing so, Westpac must satisfy the Trust Manager that the additional
features would not affect any relevant Mortgage Insurance Policy and would not
cause the rating of any Offered Notes to be downgraded or withdrawn.
 
                        THE MORTGAGE INSURANCE POLICIES
 
MORTGAGE INSURANCE POLICIES--GENERAL
 
   
    On or before the Closing Date, the Mortgage Pool Insurance Policy will be
provided by Housing Loans Insurance Corporation Limited of 31 Market Street,
Sydney NSW 2000, Australia ("HLIC") to the Issuer Trustee to cover losses in
respect of each Housing Loan that is not subject to a PMI Policy. The Mortgage
Pool Insurance Policy generally applies to loans with an LVR of 80% or less at
the Cut-Off Date. The Mortgage Pool Insurance Policy will cover losses up to a
maximum aggregate amount of A$82,000,000.
    
 
                                       77
<PAGE>
    Each Housing Loan with an LVR of greater than 80% at the time of origination
(or a lower LVR where required by Westpac's standard credit policy) will have
been insured under a PMI Policy issued by Royal & Sun Alliance Lenders Mortgage
Insurance Limited (ACN 001 825 725) of Level 9, 465 Victoria Avenue, Chatswood
NSW ("Royal & Sun"), MGICA Limited (ACN 000 511 071) of Level 23 AMP Centre, 50
Bridge Street, Sydney NSW ("MGICA"), Westpac Lenders Mortgage Insurance Limited
(ACN 074 042 934) of Level 11, 50 Pitt Street, Sydney NSW ("WLMI") or HLIC. Each
Approved Seller will equitably assign its interest in each PMI Policy to the
Issuer Trustee on the Closing Date.
 
THE HLIC MORTGAGE POOL INSURANCE POLICY
 
    GENERAL
 
    The HLIC Mortgage Pool Insurance Policy (the "Mortgage Pool Insurance
Policy") is an insurance policy put in place to cover Housing Loans that were
not insured prior to the Cut-Off Date and which had an LVR of less than or equal
to 80% as of the Cut-Off Date. Under the Mortgage Pool Insurance Policy, HLIC
will insure the Issuer Trustee with effect from the Closing Date for Finance
Charge Losses and Principal Losses in respect of the Housing Loans (other than
those Housing Loans which are individually covered by an HLIC, Royal & Sun, WLMI
or an MGICA Insurance Policy) (see "--Primary Mortgage Insurance Policies"
below).
 
PERIOD OF COVER
 
    The Issuer Trustee has the benefit of the Mortgage Pool Insurance Policy in
respect of each relevant Housing Loan from the date the Housing Loan and the
relevant Mortgage are beneficially assigned to it until the earliest of:
 
        (i) other than with respect to the assignment to the Security Trustee
    under the Security Trust Deed, the date the Housing Loan or the relevant
    Mortgage is assigned, transferred or mortgaged to a person other than a
    person who is or becomes insured under the Mortgage Pool Insurance Policy;
 
        (ii) the date the Housing Loan is repaid in full;
 
       (iii) the date the Housing Loan ceases to be secured by the relevant
    Mortgage (other than in the case where the Mortgage is discharged by the
    operation of a compulsory acquisition or sale by a government for public
    purposes);
 
        (iv) the maturity date set out in the "Certificate of Insurance" (as
    defined in the Mortgage Pool Insurance Policy), or as extended with the
    consent of the Mortgage Insurer or as varied by a court under the Consumer
    Credit Legislation; and
 
        (v) the date the Mortgage Pool Insurance Policy is cancelled in respect
    of the Housing Loan in accordance with the Mortgage Pool Insurance Policy.
 
COVER FOR LOSSES
 
    HLIC is obliged to pay to the Issuer Trustee the loss as at the Loss Date
(as defined herein) in respect of a Housing Loan, equal to the aggregate of:
 
        (i) the principal amount outstanding under such Housing Loan together
    with any interest, fees or charges (whether capitalized or not), that are
    outstanding at the Loss Date;
 
        (ii) fees and charges paid or incurred by the Issuer Trustee; and
 
       (iii) such other amounts (including fines or penalties) which HLIC
    approves in its absolute discretion;
 
                                       78
<PAGE>
    which the Issuer Trustee is entitled to recover under the relevant Housing
Loan contract and Mortgage LESS deductions including:
 
        (iv) any sale proceeds or compensation for compulsory acquisition of the
    Mortgaged Property;
 
        (v) in the event of foreclosure, the value of the Issuer Trustee's
    interest in the Mortgaged Property;
 
        (vi) any amount received by the Issuer Trustee under any collateral
    security;
 
       (vii) amounts paid to the Issuer Trustee by way of rents, profits or
    proceeds in relation to the Mortgaged Property or under any policy of
    insurance relating to the Mortgaged Property not applied in restoration or
    repair;
 
      (viii) any interest whether capitalized or not that exceeds interest at
    the (non-default) interest rate (in accordance with the Consumer Credit
    Legislation, if applicable) payable in relation to that Housing Loan;
 
        (ix) any fees or charges, whether capitalized or not, that are not of a
    type, or which exceed certain maximum amounts, as specified in the Mortgage
    Pool Insurance Policy;
 
        (x) losses directly arising out of physical damage to the Mortgaged
    Property (other than from fair wear and tear or losses recovered and applied
    in the restoration or repair of the Mortgaged Property prior to the Loss
    Date or which were recovered under a policy of insurance and applied to
    reduce the amount outstanding under the Housing Loan; and
 
        (xi) any amounts by which a claim may be reduced under the Mortgage Pool
    Insurance Policy.
 
    "Loss Date" means, in respect of a Housing Loan:
 
        (a) where, following an event on or following which the Approved Seller
    or the Issuer Trustee's power of sale in relation to the relevant Mortgaged
    Property becomes exercisable whether immediately or at the option of the
    Approved Seller or the Issuer Trustee or upon the expiration of any notice
    or period of time and whether or not the power of sale only arises if before
    the expiration of the notice or period of time the default remains
    unremedied (a "Mortgage Default"), the Approved Seller or the Issuer Trustee
    or a prior mortgagee in respect of the Mortgaged Property sells the
    Mortgaged Property, the date on which the sale is completed;
 
        (b) where, following a Mortgage Default, the Approved Seller or the
    Issuer Trustee or an approved prior mortgagee in respect of the Mortgaged
    Property becomes the absolute owner by foreclosure, the date on which that
    event occurs;
 
        (c) where, following a Mortgage Default, the Borrower sells the
    Mortgaged Property with the prior approval of the Approved Seller, the
    Issuer Trustee and HLIC, the date on which the sale is completed;
 
        (d) where the Mortgaged Property is compulsorily acquired or sold by a
    government for public purposes and there is a Mortgage Default (or where the
    Mortgage has been discharged by the operation of the compulsory acquisition
    or sale and there is a default in repayment of the loan secured by the
    Mortgage which would have been a Mortgage Default but for the occurrence of
    that event), the date being the later of the date of the completion of the
    acquisition or sale or the date twenty-eight days after the date of the
    Mortgage Default; and
 
        (e) where the HLIC has agreed or determined to pay a claim under the
    Mortgage Pool Insurance Policy, the date specified in that agreement or
    determination.

    If the Consumer Credit Legislation applies to a Mortgage, HLIC's liability
is limited to the amount required to discharge the mortgage under the Consumer
Credit Legislation.
 
AGGREGATE LIMIT
 
   
    The Mortgage Pool Insurance Policy will be subject to an aggregate limit of
loss of A$82,000,000.
    
 
ISSUER TRUSTEE'S INTEREST EXTINGUISHED
 
    If the Issuer Trustee's interest in a Housing Loan is extinguished in favor
of Westpac as a result of:
 
    (1) a breach of Westpac's representations and warranties in relation to the
Housing Loan which is discovered within 120 days of the Closing Date (or, in
relation to Housing Loans assigned to the Issuer Trustee from the assets of
another Seller Trust, 120 days after the date on which those Housing Loans were
first sold by Westpac to the Issuer Trustee in its capacity as trustee of other
Seller Trusts) and which breach was not remedied within that period (see
"WESTPAC RESIDENTIAL LOAN PROGRAM--Eligibility Criteria"); or
 
    (2) a repurchase of a Housing Loan in accordance with Westpac's right of
first refusal,
 
then Westpac will be entitled to the benefit of the Mortgage Pool Insurance
Policy in so far as it applies to that Housing Loan.
 
REFUSAL OR REDUCTION IN CLAIM
 
    The amount of a claim may be reduced or cancelled by HLIC in the following
circumstances:
 
        (i) any premium is not paid within twenty-eight days of the due date
    therefor;
 
        (ii) the Housing Loan contract for the relevant Mortgaged Property does
    not require the Mortgaged Property to be insured under a general insurance
    policy;
 
       (iii) there ceases to be a Servicer approved by HLIC to service the
    Housing Loans for the Issuer Trustee;
 
        (iv) a claim is not lodged within twenty-eight days of the relevant Loss
    Date;
 
        (v) there is any representation or statement (deemed or otherwise) in a
    proposal for a Mortgage Pool Insurance Policy that is incorrect or the duty
    of disclosure under the Mortgage Pool Insurance Policy is breached;
 
        (vi) the Issuer Trustee or the Servicer does not comply with the
    reporting obligations under the Mortgage Pool Insurance Policy;
 
       (vii) the relevant Mortgage has not been duly registered with the land
    titles office in the jurisdiction where the related Mortgaged Property is
    located; and
 
      (viii) the Housing Loan contract, the Mortgage or any collateral security
    for the relevant Mortgaged Property has not been duly stamped in each
    relevant jurisdiction.
 
    Under the Servicing Agreement, the Servicer undertakes to perform (and
indemnifies the Issuer Trustee against) certain obligations of the Issuer
Trustee, including the Issuer Trustee's duties of disclosure and its reporting
obligations under the Mortgage Pool Insurance Policy. See "--Servicer
Undertakings with Respect to Insurance Policies". This arrangement is
acknowledged in the Mortgage Pool Insurance Policy.

<PAGE>
    Circumstances in which claims under the Mortgage Pool Insurance Policy may
be reduced or cancelled also include the following events occurring in relation
to the Issuer Trustee without the approval of the Mortgage Insurer:
 
        (i) the making of any additional advance (other than Redraws) upon the
    security of a Mortgaged Property that ranks for payment ahead of the Housing
    Loan;
 
        (ii) materially altering the terms of a Housing Loan contract, any
    related Mortgage or any collateral security other than an alteration made in
    accordance with the Consumer Credit Legislation;
 
       (iii) allowing its rights to be reduced against the Borrower, the
    relevant mortgagor, any mortgage guarantor, any provider of any collateral
    security or the Mortgaged Property by compromise, postponement, partial
    discharge or otherwise;
 
        (iv) approving any transfer or assignment of the Mortgaged Property
    without full discharge of the Housing Loan;
 
        (v) a violation by the Issuer Trustee of any provision of such Mortgage
    Pool Insurance Policy; and
 
        (vi) consenting to a further advance by a prior mortgagee previously
    approved by HLIC upon the security of an approved prior mortgage.
 
EXCLUSIONS
 
    The Mortgage Pool Insurance Policy does not cover any loss arising from: (i)
any war or warlike activities; (ii) nuclear contamination; (iii) the existence
or escape of any pollution or environmentally hazardous material; (iv) the fact
that the Housing Loan contract, the relevant Mortgage or any collateral security
is void or unenforceable; or (v) where the Consumer Credit Legislation applies,
any failure of the Housing Loan contract, the relevant Mortgage or any
collateral security to comply with the requirements of the Consumer Credit
Legislation. See "CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS-- Consumer Credit
Legislation."
 
CLAIMS
 
    A claim may only be made under the Mortgage Pool Insurance Policy following
the Loss Date for the relevant Mortgage. If a Housing Loan has been in default
for at least 6 months HLIC may in its absolute discretion pay the claim for the
loss even if the Loss Date has not occurred. Claims are payable within 14 days
of receipt by HLIC of the completed claim form.
 
    HLIC may, as a condition to payment of a claim, require an assignment to it
by the Issuer Trustee (at the Issuer Trustee's expense) of rights against the
Borrower or any mortgagor or require the Issuer Trustee to take action, or
empower HLIC to take action, in relation to the relevant Housing Loan or related
Mortgage.
 
VARIATIONS
 
    HLIC may not vary the Mortgage Pool Insurance Policy for any Housing Loan
except where the variation is generally applied to all insured customers of the
same type in relation to the same type of insurance and where the variation is
necessitated to ensure that, as a consequence of a change in law after the date
of the Mortgage Pool Insurance Policy, HLIC is not in breach of the law.

HOUSING LOAN INSURANCE CORPORATION LTD (HLIC)
 
    HLIC was established in 1965 by the Commonwealth Government of Australia
("Government") and is Australia's leading lenders' mortgage insurer ("LMI") with
approximately 50% of the Australian LMI market. In December 1997, the Government
sold HLIC to GE Capital Australia ("GECA") which is a wholly owned subsidiary of
GE Capital Services Inc. ("GE").
 
    GE is a diversified industrial and financial services company with
operations in over 100 countries. It is rated AAA by Standard & Poor's, Aaa by
Moody's and AAA by Fitch. It has significant LMI business around the world,
operating in the United States, United Kingdom, Canada and now Australia and has
over US$165 billion of loans insured globally.
 
    HLIC has been given a AAA claims paying rating in its own right by Standard
& Poor's, a Aa1 rating by Moody's and a AAA rating by Fitch. Loans insured prior
to the sale to GECA will also have the benefit of a guarantee by the Government.
That proportion that has the benefit of the Government guarantee is $472,015,286
as of the Cut-Off Date.
 
PRIMARY MORTGAGE INSURANCE POLICIES
 
GENERAL
 
    Each Borrower under a Housing Loan which had an LVR of greater than 80% at
the date of origination (or a lower LVR where required by Westpac's standard
credit policy) was required to effect a mortgage insurance policy with either
Royal & Sun, MGICA, WLMI or HLIC (a "PMI Policy"). Westpac is required to
equitably assign its interest in each PMI Policy to the Issuer Trustee on the
Closing Date. The consent of Royal & Sun, MGICA, WLMI and HLIC is required for
the assignment of the relevant Mortgages and the PMI Policies, and for the
Servicer to service the insured Housing Loans. Westpac must ensure that these
consents are obtained on or prior to the Closing Date.
 
RESTRICTIONS AND CANCELLATION
 
    The amount recoverable under each PMI Policy will generally be the amount
owing in relation to the relevant Mortgage (including unpaid principal, accrued
interest at any non-default rate, proper tax and reasonable enforcement costs
(subject in certain instances to insurer's consent)) less all amounts recovered
from enforcement of the Mortgage. However, there are a number of requirements
and restrictions imposed on the insured under each PMI Policy which may entitle
the Mortgage Insurer to cancel the PMI Policy or reduce the amount of a claim;
including:
 
        (1) the existence of an encumbrance or other interest which affects or
    has priority over the Mortgage;
 
        (2) the relevant Mortgage, or a guarantee or indemnity relating to the
    Mortgage, ceasing to be effective;
 
        (3) that there is a material omission or misstatement by the insured in
    relation to the PMI Policy;
 
        (4) that any premium is not paid when due or within the relevant grace
    period (if any);
 
        (5) termination by the insurer upon the giving of a set period of
    notice;
 
        (6) a breach by the insured of the PMI Policy; and
 
        (7) certain circumstances which affect the insured's rights or
    recoveries under the relevant Housing Loan or Mortgage.
 
    Each PMI Policy has different provisions. The above is a summary of certain
provisions--some may not relate to, or may differ from, a particular PMI Policy.

                      PREPAYMENT AND YIELD CONSIDERATIONS
 
    The following information is given solely to illustrate the effect of
prepayments of the Housing Loans on the weighted average life of the Offered
Notes under the stated assumptions and is not a prediction of the prepayment
rate that might actually be experienced by the Housing Loans.
 
GENERAL
 
    The rate of principal payments on the Offered Notes, the aggregate amount of
distributions on the Offered Notes and the yield to maturity of the Offered
Notes will be related to the rate and timing of payments of principal on the
Housing Loans. The rate of principal payments on the Housing Loans will in turn
be affected by the amortization schedules of the Housing Loans and by the rate
of principal prepayments (including for this purpose prepayments resulting from
refinancing, liquidations of the Housing Loans due to defaults, casualties,
condemnations and repurchases by an Approved Seller). The Housing Loans may be
prepaid by the Mortgagors at any time (subject, in the case of fixed rate
Housing Loans, to the payment of any applicable fees).
 
PREPAYMENTS
 
    Prepayments, liquidations and purchases of the Housing Loans (including
optional purchase of the remaining Housing Loans in connection with the
termination of the Trust) will result in distributions on the Offered Notes of
principal amounts which would otherwise be distributed over the remaining terms
of such Housing Loans. Since the rate of payment of principal of the Housing
Loans will depend on future events and a variety of factors, no assurance can be
given as to such rate or the rate of principal prepayments. The extent to which
the yield to maturity of any Offered Note may vary from the anticipated yield
will depend upon the degree to which an Offered Note is purchased at a discount
or premium, and the degree to which the timing of payments thereon is sensitive
to prepayments, liquidations and purchases of such Housing Loans. The rate of
prepayment on the Housing Loans cannot be predicted. The prepayment experience
of the Trust with respect to the Housing Loans may be affected by a wide variety
of factors, including economic conditions, the availability of alternative
financing and homeowner mobility.
 
WEIGHTED AVERAGE LIVES
 
    Generally, greater than anticipated prepayments of principal will increase
the yield on Offered Notes purchased at a price less than par and will decrease
the yield on Offered Notes purchased at a price greater than par. The effect on
an investor's yield due to principal prepayments on the Housing Loans occurring
at a rate that is faster (or slower) than the rate anticipated by the investor
in the period immediately following the issuance of the Offered Notes will not
be entirely offset by a subsequent like reduction (or increase) in the rate of
principal payments. The weighted average life of the Offered Notes will also be
affected by the amount and timing of delinquencies and defaults on the Housing
Loans and the recoveries, if any, on defaulted Housing Loans and foreclosed
properties.
 
    The "weighted average life" of a note refers to the average amount of time
that will elapse from the date of issuance of the note to the date each dollar
in respect of principal repayable under such note is reduced to zero. The
weighted average life of the Offered Notes will be influenced by, among other
factors, the rate at which principal payments are made on the Housing Loans.
 
    The following tables are based on a constant prepayment rate model ("CPR").
CPR represents an assumed constant rate of prepayment each month, expressed as a
per annum percentage of the principal balance of the pool of mortgage loans for
that month. CPR does not purport to be a historical description of prepayment
experience or a prediction of the anticipated rate of prepayment of any pool of
housing loans, including the Housing Loans. None of the Approved Sellers, the
Trust Manager nor the Issuer Trustee believes that any existing statistics of
which it is aware provide a reliable basis for holders of Offered Notes to
predict the amount or the timing of receipt of prepayments on the Housing Loans.
 
                                       84
<PAGE>
    Since the following tables were prepared on the basis of the assumptions in
the following paragraph, there are discrepancies between characteristics of the
actual Housing Loans and the characteristics of the Housing Loans assumed in
preparing the tables. Any such discrepancy may have an effect upon the
percentages of the principal balances outstanding and weighted average lives of
the Offered Notes set forth in the tables. In addition, since the actual Housing
Loans in the Trust have characteristics which differ from those assumed in
preparing the tables set forth below, the distributions of principal on the
Offered Notes may be made earlier or later than as indicated in the tables.
 
    For the purpose of the tables below, it is assumed that: (i) the Closing
Date for the Offered Notes is June 9, 1998, (ii) payments on the Offered Notes
are made on the 19th day of each Quarter regardless of the day on which the
Payment Date actually occurs, commencing in July 1998 and are made in accordance
with the priorities described herein, (iii) the scheduled monthly payments of
principal and interest on the Housing Loans will be timely delivered on the
first day of each month commencing in July 1998 (with no defaults), (iv) all
prepayments are prepayments in full received on the last day of each month and
include 30 days' interest thereon, (v) Principal Collections are distributed
according to the rules of distribution set forth in "DESCRIPTION OF THE OFFERED
NOTES--Payments of Principal on the Notes"; and (vi) no optional termination is
exercised. The preceding clauses are the assumptions used in preparing the
following tables and are not necessarily expected to be predictive of the
Mortgage Pool's actual performance.
 
    It is not likely that the Housing Loans will pay at any assumed CPR to
maturity or that all Housing Loans will prepay at the same rate. The assumed CPR
for this transaction is 22.5%. In addition, the diverse remaining terms to
maturity of the Housing Loans (which include recently originated Housing Loans)
could produce slower distributions of principal than as indicated in the tables
at the assumed CPRs specified, even if the weighted average remaining term to
maturity of the Housing Loans is the same as the weighted average remaining term
to maturity of the assumptions described above. Investors are urged to make
their investment decisions on a basis that includes their determination as to
anticipated prepayment rates under a variety of the assumptions discussed herein
as well as other relevant assumptions.

                        DESCRIPTION OF THE OFFERED NOTES
 
GENERAL
 
    The Notes will be issued pursuant to the terms of the Transaction Documents.
The following section contains summaries of the material terms of the
Transaction Documents. The summaries do not purport to be complete and are
subject to the provisions of the Transaction Documents. A copy of the Master
Trust Deed, and a form of each of the Series Notice, the Note Trust Deed and the
Security Trust Deed has been filed with the Commission as an Exhibit to the
Registration Statement of which this Prospectus is a part.
 
   
    Pursuant to the Transaction Documents, on the Closing Date the Issuer
Trustee will issue two classes of notes (the "Offered Notes"), consisting of one
class of senior notes, designated as the Class A Mortgage Backed Floating Rate
Notes due July 19, 2029, in the original principal amount of US$1,372,700,000
(the "Class A Notes") and one class of subordinated notes, designated as the
Class B Mortgage Backed Floating Rate Notes, due July 19, 2029, in the original
principal amount of US$32,300,000 (the "Class B Notes"). In addition to the
Class A Notes and the Class B Notes, the Issuer Trustee may from time to time
issue RFSs, which may convert to RFS Class A Notes in certain circumstances. The
Offered Notes, the RFSs and the RFS Class A Notes are referred to herein as the
"Notes." See "--Description of the Redraw Facility, the Redraw Funding
Securities and the RFS Class A Notes" herein.
    
 
    Payments on the Offered Notes will be made by the Principal Paying Agent on
each Payment Date to persons in whose names the Notes are registered as of the
related Record Date (the "Holders" or "Offered Noteholders"). The Payment Date
for the Notes will be the 19th day of each Quarter. A "Quarter" is each
three-month period in a year which period begins on July 1, October 1, January 1
and April 1. If any Payment Date would otherwise fall on a day which is not a
Business Day, it shall be postponed to the next day which is a Business Day
unless it would thereby fall into the next calendar month in which event it
shall be brought forward to the immediately preceding Business Day. The first
Payment Date will be July 20, 1998 in respect of the period from (and including)
the Closing Date to (but excluding) that date. The Record Date for any Payment
Date will be the second Business Day immediately preceding the Payment Date (so
long as the Offered Notes are held in book-entry form), or the last day of the
prior calendar month (if Definitive Notes have been issued).
 
    A "Business Day" means (1) in relation to the Note Trust Deed, the Agency
Agreement and any Note, any day, other than a Saturday, Sunday or public
holiday, on which banks are open for business in Sydney, London and New York
City; (2) in relation to US$ payments under a Currency Swap, any day, other than
a Saturday, Sunday or public holiday, on which banks are open for business in
London and New York City; and (3) in relation to A$ payments under the Currency
Swap and any other Transaction Document, any day, other than a Saturday, Sunday
or public holiday, on which banks are open for business in Sydney. If a public
holiday is occurring in any of the referenced locales, then such day is not a
Business Day, and no scheduled payments will be made on such day.
 
    A "Collection Period" commences on and includes the 10th day of each Quarter
and runs until (and includes) the 9th day of the following Quarter with the
exception of the first Collection Period, which will commence on (and include)
the day after the Cut-Off Date and end on (and include) July 9, 1998. The last
Collection Period is the period from the last day of the previous Collection
Period to the Termination Date of the Trust.
 
    The first Interest Period in relation to the Notes commences on (and
includes) the Closing Date and ends on (but excludes) the first Payment Date
(being July 20, 1998). Each succeeding Interest Period, commences on (and
includes) a Payment Date and ends on (but excludes) the next Payment Date. The
final Interest Period ends on (but excludes) the Maturity Date.
 
    For any Interest Period other than the initial Interest Period, the
"Interest Determination Date" is the second Business Day prior to the
commencement of that Interest Period. The first Interest Determination Date,
which relates to the Interest Period beginning July 20, 1998, is July 16, 1998.
The "Collection
 
                                       88
<PAGE>
Determination Date" is four Business Days prior to each Payment Date with the
exception of the first Collection Determination Date, which will be July 9,
1998.
 
    Each Class of Offered Notes initially will be represented by one or more
global notes (the "Book-Entry Notes") registered in the name of the nominee of
DTC (together with any successor depository, the "Depository"), except as set
forth below. Beneficial interests in each Class of Offered Notes will be
available for purchase in minimum denominations of US$100,000. The Issuer
Trustee has been informed by DTC that DTC's nominee will be Cede & Co.
Accordingly, Cede & Co. is expected to be the Noteholder of record of the
Offered Notes. Unless and until Definitive Notes are issued under the limited
circumstances described herein, no Note Owner (as defined herein) acquiring an
interest in any Class of Offered Notes will be entitled to receive a certificate
representing such Note Owner's interest in such Notes. Until such time, all
references herein to actions by Noteholders of any Class of Offered Notes will
refer to actions taken by the Depository upon instructions from its
participating organizations and all references herein to distributions, notices,
reports and statements to Noteholders of any Class of Offered Notes will refer
to distributions, notices, reports and statements to the Depository or its
nominee, as the registered Noteholder of such Class, for distribution to Note
Owners of such Class in accordance with the Depository's procedures. See
"--Book-Entry Registration" and "--Definitive Notes."
 
    The Issuer Trustee will maintain a Paying Agent in London until the date the
Offered Notes are redeemed.
 
COLLECTIONS AND PAYMENT
 
    With respect to each Collection Period and on or prior to the Collection
Determination Date, the Trust Manager will determine the Collections (as defined
below) received and reconcile such receipts against expenses, including Interest
payable to Noteholders, that have accrued during such Collection Period. To the
extent necessary, the Trust Manager must direct the Issuer Trustee to draw on or
claim against the Liquidity Facility where available to make up shortfalls in
Collections. Various amounts will also be swapped under the Swap Agreements.
 
    On the Collection Determination Date, the Trust Manager shall advise the
Issuer Trustee of the amounts to be paid. The Issuer Trustee will arrange for
the relevant payments to occur on the Payment Date.
 
    Set out below is an example of relevant dates and periods for the allocation
of cashflows and their payments. All dates are assumed to be Business Days.

</TABLE>
 
COLLECTIONS
 
    With respect to any Collection Period, "Collections" shall consist of
interest and principal receipts from the Housing Loans, the proceeds of
enforcement of Mortgages, the proceeds of claims under Mortgage Insurance
Policies and payments by the Approved Sellers or the Servicer in respect of
breaches of representations or warranties with respect to the Housing Loans.
Westpac or the Servicer, as a delegate
 
                                       89
<PAGE>
of Westpac under the Servicing Agreement, will receive the Collections in
respect of the Housing Loans in the Mortgage Pool.
 
    So long as both (a) Westpac has a short term rating of at least A-1+ from
Standard & Poor's, P-1 from Moody's and F-1+ from Fitch and (b) the Collections
Account is maintained with Westpac or a subsidiary of Westpac, each of Westpac
and the Servicer shall deposit the amount equal to the Collections it receives
during the related Collection Period into the relevant Collections Account two
Business Days prior to the relevant Payment Date (the "Remittance Date")
together with an amount equivalent to the interest that would have accrued at
the Bank Bill Rate on such amounts if such receipts had been deposited into the
Collections Account five Business Days following receipt by Westpac or the
Servicer (less any relevant tax).
 
    If Westpac has a short term rating of less than A-1+ from Standard & Poor's,
less than P-1 from Moody's or less than F-1+ from Fitch, then Westpac and the
Servicer shall pay all Collections in its possession or control into the
Collections Account no later than five Business Days following receipt.
Notwithstanding the foregoing, the Collections Account may continue to be
maintained with Westpac for so long as it is an Approved Bank. An "Approved
Bank" means: (a) a bank which has a short term rating of at least A-1+ from
Standard & Poor's, P-1 from Moody's and F-1+ from Fitch; or (b) any bank or
financial institution which is specified to be an Approved Bank in the Series
Notice, but means Westpac for so long as it has a short term rating of A-1 or
better from Standard & Poor's, P-1 or better from Moody's and F-1 or better from
Fitch.
 
    If, however, the Collections Account is not maintained with Westpac, or a
subsidiary of Westpac, all Collections in relation to the Trust must be
deposited into the Collections Account no later than two Business Days following
receipt thereof by Westpac or the Servicer (as the case may be).
 
CALCULATION OF TOTAL AVAILABLE FUNDS
 
    On each Collection Determination Date the Trust Manager will, for the
immediately preceding Collection Period, calculate the total of the Available
Income, plus Principal Draws, plus Liquidity Draws (the sum of such amounts, the
"Total Available Funds"), all as further described below.
 
AVAILABLE INCOME
 
    "Available Income" for a Collection Period equals the aggregate of:
 
        (1) Finance Charge Collections;
 
    plus to the extent not included in paragraph (1):
 
        (2) any amount received or due to be received by or on behalf of the

        (ii) from an Approved Seller or the Servicer under any obligation under
             the Master Trust Deed, Servicing Agreement or Series Notice to

    With respect to any Housing Loan, a "Finance Charge Loss" means Liquidation
Losses which are attributable to interest, fees and expenses in relation to the
relevant Housing Loan, including on the early discharge of Housing Loans which
bear a fixed rate of interest (other than a Housing Loan subject to an
introductory rate of interest for 12 months or less) the amount, if any, owed by
the relevant Borrower in accordance with the Relevant Documents. With respect to
any Housing Loan, "Liquidation Losses" for a Collection Period, means the amount
(if any) by which the Unpaid Balance of a Housing Loan (together with the
enforcement expenses relating to the Housing Loan and the related Mortgage)
exceeds the Liquidation Proceeds in relation to the Housing Loan. "Liquidation
Proceeds" means all amounts recovered from the enforcement of a Mortgage
(excluding proceeds of a Mortgage Insurance Policy).
 
    With respect to any Housing Loan, a "Prepayment Cost Surplus" means, in
relation to a Collection Period, the amount by which the total of all Prepayment
Costs (as defined below) for that Collection Period exceeds the total of all
Prepayment Benefits (as defined herein) for that Collection Period. With respect
to any Housing Loan, a "Prepayment Benefit Shortfall" means, in relation to a
Collection Period,

means, on the early discharge of such Housing Loan, the amount (if any) owed by
the relevant Borrower and collected by Westpac or the Servicer, in accordance
with the relevant Housing Loan agreement with respect to such early discharge.
With respect to any Housing Loan which is a Fixed Option Home Loan or otherwise
bears a fixed rate of interest (other than a Housing Loan subject to an

to the relevant Borrower's loan account by Westpac by means of a reduction in
the Housing Loan Principal of that Housing Loan, in accordance with the relevant
Housing Loan agreement.
 
    With respect to a Collection Period and any Housing Loan, "Principal Loss"
means the amount of any Liquidation Loss for that Collection Period which is
attributable to principal in relation to the relevant Housing Loan.
 
PRINCIPAL DRAWS
 
    If the Trust Manager determines on any Collection Determination Date that
the Available Income of the Trust for the Collection Period ending immediately
prior to that Collection Determination Date is insufficient to meet Total
Payments (as defined herein under "--Distribution of Total Available Funds") of
the Trust for that Collection Period (a "Payment Shortfall"), then Principal
Collections collected during that Collection Period will be applied to the
Payment Shortfall (a "Principal Draw") to the extent available for this purpose.
 
    Principal Draws will be reimbursed out of any Excess Available Income
available for this purpose on subsequent Payment Dates.
 
LIQUIDITY DRAWS
 
    If, on any Collection Determination Date, the Trust Manager determines that
the related Payment Shortfall, if any, will not be covered fully by a Principal
Draw, the Trust Manager must direct the Issuer Trustee to draw on the Liquidity
Facility in an amount equal to the lesser of the remaining Payment Shortfall or
the Available Liquidity Amount. Any direction by the Trust Manager to the Issuer
Trustee to draw on the Liquidity Facility is subject to there being available
funds under the Liquidity Facility.
 
REMAINING LIQUIDITY SHORTFALL
 
    If the amount available to be drawn under the Liquidity Facility is not
sufficient to satisfy the remaining Payment Shortfall in full, the amount of
such shortfall will be a "Remaining Liquidity Shortfall." If the Trust Manager
determines that a Remaining Liquidity Shortfall exists, then the Trust Manager
must reduce the Interest payable in respect of the Notes as follows:
 
        (1) first, reduce the A$ Class B Interest Amount payable to the Currency
    Swap Provider under the swap confirmation relating to the Class B Notes;
 
        (2) second, if the A$ Class B Interest Amount has been reduced to zero,
    any excess Remaining Liquidity Shortfall shall reduce PRO RATA, based on
    their applicable entitlements:
 
        (i) the A$ Class A Interest Amount payable to the Currency Swap
            Providers under the swap confirmation relating to the Class A Notes;
 
        (ii) the RFS Interest for all RFSs (if any);
 
       (iii) interest payable for all RFS Class A Notes (if any); and
 
                                       92
<PAGE>
        (iv) any fee payable by the Issuer Trustee under the Redraw Facility.
 
    If there is a reduction in the A$ Class B Interest Amount under (1) above,
the Interest entitlement of the Class B Noteholders shall be reduced by the same
proportion as the reduction in the A$ Class B Interest Amount. If there is a
reduction in the A$ Class A Interest Amount under (2)(i) above, the Interest
entitlement of the Class A Noteholders shall be reduced by the same proportion
as the reduction in the A$ Class A Interest Amount.
 
    With respect to any Payment Date, the "A$ Class A Interest Amount" means the
amount in A$ which is calculated:
 
        (1) on a daily basis at the applicable rate set out in the swap
    confirmation relating to the Class A Notes (being AUD- BBR-BBSW, as defined
    in the ISDA Definitions, as at the first day of the Interest Period ending
    on (but excluding) that Payment Date with a designated maturity of 90 days
    plus the spread set out in the Currency Swaps);
 
        (2) on the A$ Equivalent (with respect to an amount denominated or to be
    denominated in U.S. dollars, the amount converted to (and denominated in)
    Australian dollars at the applicable exchange rate set forth in the Currency
    Swaps) of the aggregate of the Invested Amount of the Class A Notes as at
    the first day of the Interest Period ending on (but excluding) that Payment
    Date; and
 
        (3) on the basis of the actual number of days in that Interest Period
    and a year of 365 days.
 
    With respect to any Payment Date, the "A$ Class B Interest Amount" means,
for any Payment Date, the amount in A$ which is calculated:
 
        (1) on a daily basis at the applicable rate set out in the swap
    confirmation relating to the Class B Notes (being AUD- BBR-BBSW, as defined
    in the ISDA Definitions, as at the first day of the Interest Period ending
    on (but excluding) that Payment Date with a designated maturity of 90 days
    plus the spread set forth in the Currency Swaps);
 
        (2) on the A$ Equivalent of the aggregate of the Invested Amount of the
    Class B Notes as at the first day of the Interest Period ending on (but
    excluding) that Payment Date; and
 
        (3) on the basis of the actual number of days in that Interest Period
    and a year of 365 days.
 
    With respect to any Payment Date, "RFS Interest" means all interest on the
outstanding RFSs in respect of an Interest Period. With respect to any Payment
Date, "RFS Class A Interest" means all interest on the outstanding RFS Class A
Notes in respect of an Interest Period.
 
DISTRIBUTION OF TOTAL AVAILABLE FUNDS
 
GENERAL
 
    On each Payment Date, the Trust Manager shall instruct the Issuer Trustee to
apply the Total Available Funds in making the following payments in respect of
the preceding Collection Period in the following order of priority:
 
        (1) in relation to the first Payment Date only, the Accrued Interest
    Adjustment;
 
        (2) unpaid or unreimbursed Trust Expenses;
 
        (3) amounts payable under any Support Facility (other than the Currency
    Swaps), PARI PASSU, based on their respective entitlements, including:
 
        (i) the net amount (if any) payable by the Issuer Trustee under the
            Variable Rate Basis Swap;
 
        (ii) the net amount (if any) payable by the Issuer Trustee under each
             Fixed Rate Basis Swap; and
 
       (iii) any interest or fees payable by the Issuer Trustee under the
             Liquidity Facility,
 
                                       93
<PAGE>
          but not including amounts due under paragraph (4), (5) or (6) below;
 
        (4) repayment of any Liquidity Draw made on or prior to the previous
    Payment Date;
 
        (5) PARI PASSU, to each of the following, based on their respective
    entitlements:
 
        (i) any interest payable on all RFSs (if any);
 
        (ii) the payment to the Currency Swap Providers under the swap
             confirmation relating to the Class A Notes of the A$ Class A
             Interest Amount at that date;
 
       (iii) the interest payable on all RFS Class A Notes (if any); and
 
        (iv) any fee payable by the Issuer Trustee under the Redraw Facility;
             and
 
        (6) the payment to the Currency Swap Providers under the swap
    confirmation relating to the Class B Notes of the A$ Class B Interest Amount
    as at that date.
 
    The sum of paragraphs (1) to (6) above represents "Total Payments" for a
Collection Period.
 
    The Issuer Trustee shall only make a payment described in paragraphs (1)
through (6) above to the extent that Total Available Funds remain available to
do so after each payment is made in accordance with the above priority in
accordance with the Series Notice.
 
TRUST EXPENSES
 
    On each Collection Determination Date the Trust Manager will determine the
following payments to be made for the relevant Collection Period (together, the
"Trust Expenses") in the following order of priority (as between themselves) on
the next Payment Date:
 
        (1) taxes payable in relation to the Trust;
 
        (2) the Issuer Trustee Fee;
 
        (3) the Trust Manager Fee;
 
        (4) any fee payable to the Security Trustee under the Security Trust
    Deed;
 
        (5) the Servicing Fee;
 
        (6) any fee payable to the Note Trustee under the Note Trust Deed;
 
        (7) any fees payable to the Principal Paying Agent, the Agent Bank and
    any other agents under the Agency Agreement;
 
        (8) PARI PASSU based on their respective entitlements any costs, charges
    or expenses (other than fees) incurred by, and any liabilities owing under
    any indemnity granted to, the Security Trustee, the Servicer, the Note
    Trustee and a Paying Agent and any other agents or the Agent Bank in
    relation to the Trust under the Transaction Documents, for that Collection
    Period; and
 
        (9) PARI PASSU based on their respective entitlements any other costs,
    charges or expenses incurred by the Issuer Trustee or the Trust Manager in
    the administration or operation of the Trust.
 
CALCULATION OF INTEREST PAYABLE ON THE NOTES
 
    The "Interest Rate" for the Class A Notes for a particular Interest Period
is equal to USD-LIBOR-BBA on the related Interest Determination Date (as defined
herein) plus    %. The Interest Rate on the Class A Notes for the first Interest
Period will be equal to    %. The "Interest Rate" for the Class B Notes for a
particular Interest Period is equal to USD- LIBOR-BBA on the related Interest
Determination Date plus    %. The Interest Rate on the Class B Notes for the
first Interest Period will be equal to    %. See "--Calculation of
USD-LIBOR-BBA" below.
 
                                       94
<PAGE>
    With respect to any Payment Date, interest on a Class of Notes will be
calculated as the product of (a) the Invested Amount of such Class as of the
first day of that Interest Period after giving effect to any payments of
principal made with respect to such Class on such day, (b) the Interest Rate for
such Class for that Interest Period; and (c) a fraction, the numerator of which
is the actual number of days in that Interest Period and the denominator of
which is 360 days (such product, "Interest"). No Noteholder will be entitled to
payments of Interest after the related Stated Amount is reduced to zero.
 
CALCULATION OF USD-LIBOR-BBA
 
    On the second London banking day before the beginning of each Interest
Period (each an "Interest Determination Date"), the Agent Bank will determine
the "USD-LIBOR-BBA" as the applicable Floating Rate Option under the Definitions
of the International Swaps and Derivatives Association, Inc. ("ISDA") (the "ISDA
Definitions") being the rate applicable to any Interest Period for three-month
deposits in U.S. dollars which appears on the Telerate Page 3750 as of 11:00
A.M., London time, on the Interest Determination Date. If such rate does not
appear on the Telerate Page 3750, the rate for that Interest Period will be
determined as if the Issuer Trustee and Agent Bank had specified
"USD-LIBOR-Reference Banks" as the applicable Floating Rate Option under the
ISDA Definitions. "USD-LIBOR-Reference Banks" means that the rate for an
Interest Period will be determined on the basis of the rates at which deposits
in U.S. Dollars are offered by the Reference Banks (being four major banks in
the London interbank market) at approximately 11:00 A.M., London time, on the
Interest Determination Date to prime banks in the London interbank market for a
period of three months commencing on the first day of the Interest Period and in
a Representative Amount (as defined in the ISDA Definitions). The Agent Bank
will request the principal London office of each of the Reference Banks to
provide a quotation of its rate. If at least two such quotations are provided,
the rate for that Interest Period will be the arithmetic mean of the quotations.
If fewer than two quotations are provided as requested, the rate for that
Interest Period will be the arithmetic mean of the rates quoted by major banks
in New York City, selected by the Agent Bank, at approximately 11:00 A.M., New
York City time, on that Interest Determination Date for loans in U.S. dollars to
leading European banks for a period of three months commencing on the first day
of the Interest Period and in a Representative Amount, provided that on the
first day of the first Interest Period USD-LIBOR-BBA shall be an interpolated
rate calculated with reference to the period from (and including) the Closing
Date to (but excluding) the first Payment Date.
 
EXCESS AVAILABLE INCOME
 
GENERAL
 
    On each Collection Determination Date, the Trust Manager must determine the
amount (if any) by which the Total Available Funds for the Collection Period
ending immediately prior to that Collection Determination Date exceeds the Total
Payments for that same Collection Period (such amount, the "Excess Available
Income").
 
DISTRIBUTION OF EXCESS AVAILABLE INCOME
 
    On each Collection Determination Date, the Trust Manager must apply such
Excess Available Income for the Collection Period relating to that Collection
Determination Date in the following order of priority:
 
        (1) to reimburse Principal Charge Offs for that Collection Period;
 
        (2) PARI PASSU and rateably, based on the Stated Amount of the RFSs (if
    any), the Stated Amount of the RFS Class A Notes (if any), the Principal
    Outstanding under the Redraw Facility and the A$ Equivalent of the Stated
    Amount of the Class A Notes:
 
           (i) as a payment to the holders of the RFSs (if any) in or towards
       reinstating the Stated Amount of such RFSs, to the extent of any
       Carryover RFS Charge Offs;
 
                                       95
<PAGE>
           (ii) as a payment to the holders of the RFS Class A Notes (if any) in
       or towards reinstating the Stated Amount of such RFS Class A Notes, to
       the extent of any Carryover RFS Class A Charge Offs;
 
           (iii) as a repayment under the Redraw Facility Agreement, as a
       reduction of, and to the extent of, any Carryover Redraw Charge Offs;
 
           (iv) as a payment to the Currency Swap Providers under the swap
       confirmations relating to the Class A Notes, of the A$ Equivalent of any
       Carryover Class A Charge Offs; and
 
        (3) as a payment, denominated in A$, to the Currency Swap Providers
    under the swap confirmation relating to the Class B Notes of the A$
    Equivalent of any Carryover Class B Charge Offs;
 
        (4) to all Principal Draws which have not been repaid as at that date;
    and
 
        (5) as a distribution to any Beneficiaries (an "Excess Collections
    Distribution").
 
    All amounts to be paid pursuant to paragraphs (2), (3) and (5) will be paid
on the Payment Date immediately following the Collection Determination Date.
 
    Once distributed to a Beneficiary, an Excess Collections Distribution will
not be available to the Issuer Trustee to meet its obligations in respect of the
Trust in subsequent periods unless there has been an error in the relevant
calculation of the Excess Collections Distribution. A "Beneficiary" is any party
which holds a residual income unit in the Trust. The Issuer Trustee does not
intend and is not permitted to accumulate any surpluses.
 
GROSS PRINCIPAL COLLECTIONS
 
    On each Collection Determination Date, the Trust Manager must determine
Gross Principal Collections for the Collection Period ending immediately prior
to that Collection Determination Date. With respect to any Collection
Determination Date, "Gross Principal Collections" are the sum of:
 
        (1) all amounts received by or on behalf of the Issuer Trustee from or
    on behalf of Borrowers under or in respect of the Housing Loans during the
    Collection Period in respect of principal, including principal prepayments;
 
        (2) all other amounts received under or in respect of the Housing Loans
    during the Collection Period in respect of principal, including:
 
           (i) Liquidation Proceeds received on account of principal;
 
           (ii) any payments by Westpac to the Issuer Trustee on the repurchase
       of a Housing Loan in respect of principal;
 
           (iii) any amounts in the nature of principal received by or on behalf
       of the Issuer Trustee from the sale of any Trust Asset, including any
       amount received on the issue of Notes and which was not used to purchase
       a Housing Loan or Mortgage and which the Trust Manager determines is
       surplus to the requirements of the Trust;
 
           (iv) any Prepayment Costs applied towards Prepayment Benefit; and
 
           (v) any Prepayment Benefit Shortfall paid by Westpac to the Trust;
 
        (3) all amounts received by or on behalf of the Issuer Trustee during
    that Collection Period under any Support Facility (other than the Currency
    Swaps) which the Trust Manager determines should be accounted for to reduce
    a Principal Loss;
 
                                       96
<PAGE>
        (4) all amounts received by or on behalf of the Issuer Trustee during
    that Collection Period:
 
           (i) from an Approved Seller or the Servicer in respect of any breach
       of a representation, warranty or undertaking contained in the Master
       Trust Deed, Series Notice or Servicing Agreement determined by the Trust
       Manager to be in respect of principal; and
 
           (ii) from an Approved Seller or the Servicer under any obligation
       under the Master Trust Deed, Series Notice or Servicing Agreement to
       indemnify, reimburse or pay damages to the Issuer Trustee for any amount
       determined by the Trust Manager to be in respect of principal;
 
        (5) any amount of Excess Available Income to be applied to meet a
    Principal Charge Off or a Carryover Charge Off;
 
        (6) any amount received by or on behalf of the Issuer Trustee during
    that Collection Period as proceeds from the issue of any RFS to the extent
    not applied to reimburse amounts drawn under the Redraw Facility;
 
        (7) any Excess Available Income to be applied to Principal Draws made on
    a previous Payment Date;
 
        (8) any Prepayment Calculation Adjustment for that Collection Period;
    and
 
        (9) any net amount attributable to principal received by the Trust from
    another trust established under the Master Trust Deed with respect to any
    substitution of a Housing Loan during that Collection Period ("Substitution
    Net Transfer Amount (Principal)");
 
but excluding a premium receivable by the Issuer Trustee on entry into a
replacement Currency Swaps.
 
    On the Closing Date, the A$ Equivalent of the total Initial Invested Amount
of the Notes issued by the Issuer Trustee may exceed the Housing Loan Principal
as of the Cut-Off Date. The amount of this difference, if any, will be treated
as a Gross Principal Collection and the US$ Equivalent will be passed through to
Noteholders on the first Payment Date.
 
    With respect to any Collection Period and a Housing Loan, a "Prepayment
Calculation Adjustment" is any amount credited to the related Borrower by
Westpac to reflect an interest adjustment resulting from a change in computer
systems.
 
PRINCIPAL COLLECTIONS
 
    On each Collection Determination Date the Trust Manager must calculate
Principal Collections for the preceding Collection Period. With respect to any
Collection Determination Date, "Principal Collections" shall be equal to:
 
        (1) the Gross Principal Collections for that Collection Period; less
 
        (2) any amounts deducted by or paid to Westpac to reimburse Redraws
    funded by Westpac during that Collection Period for which Westpac has not
    been reimbursed previously.
 
DISTRIBUTION OF PRINCIPAL COLLECTIONS
 
INITIAL PRINCIPAL DISTRIBUTIONS
 
    On each Payment Date, Principal Collections will be distributed in the
following order of priority:
 
        (1) to repay any Redraws provided by Westpac to the extent not
    previously reimbursed;
 
        (2) to repay any Principal Outstanding under the Redraw Facility;
 
        (3) to allocate to Total Available Funds any Principal Draw; and
 
                                       97
<PAGE>
        (4) to repay all amounts outstanding under each RFS Series (if any), in
    chronological order of issue, until repaid in full,
 
(together, "Initial Principal Distributions").
 
    Only after Initial Principal Distributions have been distributed will
Principal Collections be available to be paid to the Currency Swap Providers to
enable the Issuer Trustee to make payments to the Class A Noteholders and the
Class B Noteholders in US$ in accordance with the appropriate principal
allocation methodology set forth below. With respect to any Payment Date, "Net
Principal Collections" shall equal the amount of Principal Collections remaining
after the distribution of Initial Principal Distributions.
 
PAYMENTS OF PRINCIPAL ON THE NOTES
 
    With respect to any Collection Determination Date, the Trust Manager shall
determine the appropriate principal allocation methodology as set forth below.
On each Payment Date, the Trust Manager shall instruct the Issuer Trustee to pay
principal to the Noteholders in the manner and subject to the priority set forth
below.
 
SERIAL METHOD 1
 
    If, on the related Collection Determination Date, the Serial Method 1
Distribution Test has been met, then the Issuer Trustee will pay out of any Net
Principal Collections, on the immediately following Payment Date the following
amounts in the following order of priority:
 
        (1) first, PARI PASSU and rateably, based on their respective
    entitlements:
 
           (i) as a payment, denominated in A$, to the Currency Swap Providers
       under the swap confirmations relating to the Class A Notes of an amount
       equal to the lesser of:
 
               (a) the Class A Forex Percentage of the sum of: (1) the Class A
           Percentage of Net Principal Collections; and (2) 50% of the Class B

APPLICATION OF PRINCIPAL CHARGE OFFS
 
GENERAL
 
    If there is any Liquidation Loss under a Housing Loan, the Trust Manager
will direct the Servicer to make a claim under the relevant Mortgage Insurance
Policy for the aggregate amount of that Liquidation Loss if the Servicer has not
already done so. If a claim on account of a Principal Loss may not be made (or
is reduced) under the Mortgage Insurance Policy for any reason (including
because the maximum amount available under the Mortgage Pool Insurance Policy
has been exhausted, the Mortgage Insurance Policy has been terminated in respect
of that Housing Loan, the Mortgage Insurer is entitled to reduce the amount of
the claim or the Mortgage Insurer defaults in payment of a claim) then a
"Mortgage Shortfall" will arise if:
 
        (1) the total amount recovered and recoverable under the Mortgage
    Insurance Policy attributable to principal; plus
 
        (2) any damages or other amounts payable by an Approved Seller or the
    Servicer under or in respect of the Master Trust Deed, the Series Notice or
    Servicing Agreement relating to the Housing Loan which the Trust Manager
    determines to be on account of principal, is insufficient to meet the full
    amount of the Principal Loss. In that case, the aggregate amount of all
    Mortgage Shortfalls for that Collection Period (a "Principal Charge Off")
    will be applied to reduce the Stated Amounts of the Notes as described
    below.
 
CHARGE OFFS
 
    On any Collection Determination Date, the Excess Available Income (if any)
will be applied to meet Principal Charge Offs calculated on that Collection
Determination Date for the Collection Period ending immediately prior to that
Collection Determination Date. If the amount of Excess Available Income is less
than the amount of those Principal Charge Offs, then the balance of the
Principal Charge Offs will be:
 
        (1) applied to reduce the Stated Amounts of the Class B Notes by the US$
    Equivalent of that balance (a "Class B Charge Off"), until the Class B
    Stated Amount is zero; and
 
        (2) to the extent that balance cannot be applied under paragraph (1)
    because the Class B Stated Amount is zero, applied PARI PASSU and rateably,
    based on their respective Stated Amounts or Principal Outstanding, as
    applicable, to the reduction of the RFSs (if any) (an "RFS Charge Off"), the
    RFS Class A Notes (if any) (an "RFS Class A Charge Off") and the Class A
    Notes (a "Class A Charge Off") until the respective Stated Amounts of the
    Class A Notes, the RFSs (if any) and the RFS Class A Notes (if any) are zero
    and the Principal Outstanding under the Redraw Facility until the Principal
    Outstanding is zero (a "Redraw Facility Charge Off") (using A$ Equivalent
    amounts in the case of the Class A Notes).
 
                                      101
<PAGE>
    With respect to any date, the "Total Carryover Charge Off" means the sum of:
 
           (1) all Carryover Class A Charge Offs for all Class A Notes (other
       than RFS Class A Notes) as at that date;
 
           (2) all Carryover Class B Charge Offs for all Class B Notes as at
       that date;
 
           (3) the US$ Equivalent of all Carryover RFS Charge Offs for all RFSs
       as at that date; and
 
           (4) the US$ Equivalent of all Carryover RFS Class A Charge Offs for
       all RFS Class A Charge Offs as at that date.
 
REIMBURSEMENT OF CHARGE OFFS
 
    On any Collection Determination Date, if there is Excess Available Income in
respect of the Collection Period ending immediately prior to that Collection
Determination Date remaining after the reimbursement of any Principal Charge
Offs for that Collection Period, then the remaining Excess Available Income will
be used to reinstate the Stated Amounts of the Notes in the following priority:
 
        (1) first, the Carryover Redraw Charge Offs, Carryover RFS Charge Offs,
    Carryover RFS Class A Charge Offs and Carryover Class A Charge Offs, PARI
    PASSU and rateably based on the amount of their respective Charge Offs
    (using A$ Equivalent amounts in the case of Carryover Class A Charge Offs);
    and
 
        (2) second, the A$ Equivalent of any Carryover Class B Charge Offs.
 
    On any Collection Determination Date in relation to a Class A Note,
"Carryover Class A Charge Offs" means the aggregate of Class A Charge Offs in
relation to that Class A Note prior to that Collection Determination Date which
have not been reinstated as provided for herein. On any Collection Determination
Date in relation to a Class B Note, "Carryover Class B Charge Offs" means on any
Collection Determination Date in relation to a Class B Note, the aggregate of
Class B Charge Offs in relation to that Class B Note prior to that Collection
Determination Date which have not been reinstated as provided for herein. On any
Collection Determination Date in relation to the Redraw Facility, "Carryover
Redraw Charge Offs" means, the aggregate of Redraw Charge Offs prior to that
Collection Determination Date which have not been reinstated as provided for
herein. On any Collection Determination Date in relation to the RFSs, the
aggregate of RFS Charge Offs in relation to that RFS prior to that Collection
Determination Date which have not been reinstated as provided for herein. On any
Collection Determination Date in relation to an RFS Class A Note, "Carryover RFS
Class A Charge Offs" means the aggregate of RFS Class A Charge Offs in relation
to that RFS Class A Note prior to that Collection Determination Date which have
not been reinstated as provided for herein.
 
PAYMENTS INTO US$ ACCOUNT
 
    The Principal Paying Agent shall open and maintain, or cause to be opened
and maintained, an account (the "US$ Account") into which the Currency Swap
Providers shall deposit amounts denominated in US$.
 
        (1) The Issuer Trustee shall direct the Currency Swap Providers to pay
    all amounts denominated in US$ payable to the Issuer Trustee by the Currency
    Swap Providers under the Currency Swaps into the US$ Account or to the
    Principal Paying Agent under the Agency Agreement on behalf of the Issuer
    Trustee.
 
        (2) If any of the Issuer Trustee, the Trust Manager or the Servicer
    receives any amount denominated in US$ from the Currency Swap Providers
    under the Currency Swaps they will promptly pay that amount to the credit of
    the US$ Account.

PAYMENTS OUT OF US$ ACCOUNT
 
    The Issuer Trustee shall, or shall require that the Paying Agents shall on
its behalf, pay all amounts credited to the US$ Account or otherwise referred to
above to meet its US$ obligations under the Series Notice and the Notes, and in
accordance with the Note Trust Deed and the Agency Agreement.
 
PREPAYMENT COSTS AND PREPAYMENT BENEFITS
 
    (1) On each Collection Determination Date the Trust Manager will determine
total Prepayment Benefits and total Prepayment Costs for the relevant Collection
Period and will apply an amount equal to those total Prepayment Costs in payment
of those total Prepayment Benefits. If:
 
        (i) there is a Prepayment Cost Surplus, it will be applied under
    paragraph (2) below; and
 
        (ii) there is a Prepayment Benefit Shortfall, it will be funded under
    paragraph (3) below.
 
    (2) On each Payment Date, based on calculations provided to it by the Trust
Manager, the Issuer Trustee will pay to Westpac an amount equal to the
Prepayment Cost Surplus (if any) for the Collection Period on that Payment Date
to the extent received by or on behalf of the Issuer Trustee.
 
    (3) If, on any Collection Determination Date, the Trust Manager calculates
that there is a Prepayment Benefit Shortfall, the Trust Manager must by the
close of business on that Collection Determination Date notify Westpac of the
amount of that Prepayment Benefit Shortfall. Westpac must, by 4:00 p.m. (Sydney
time) on the Remittance Date, deposit in the Collections Account for the credit
of the Issuer Trustee an amount equal to that Prepayment Benefit Shortfall. That
amount will be treated as a Gross Principal Collection.
 
DESCRIPTION OF THE REDRAW FACILITY, THE REDRAW FUNDING SECURITIES AND THE RFS
  CLASS A NOTES
 
    Certain Housing Loans in the Mortgage Pool which are charged a variable rate
of interest have a feature which allows the borrower to draw on repayments made
by the Borrower in excess of scheduled repayments on the related Housing Loan
(any such draw, a "Redraw"). Under a Redraw, Borrowers may require Westpac to
re-advance to them previously prepaid principal. In certain circumstances,
Westpac has a contractual obligation under the related loan document to provide
the Redraw if the Borrower has made prepayments on the related Housing Loan and
such Borrower is not delinquent. A Redraw will not result in the Housing Loan
being removed from the Mortgage Pool.
 
    Westpac is entitled to be reimbursed by the Issuer Trustee for Redraws
funded by Westpac first, from Gross Principal Collections as described under
"--Principal Collections" herein, second, from drawings under the Redraw
Facility and third, from the proceeds of the issuance of RFSs, to the extent
each is available.
 
    If Westpac is not fully reimbursed in relation to a Redraw, it will bear the
cost of funding that Redraw until such time as it can be reimbursed by the
Issuer Trustee.
 
REDRAW FACILITY
 
GENERAL
 
    On or prior to the Closing Date, Westpac will enter into a Redraw Facility
Agreement (the "Redraw Facility Agreement") in its capacity as "Redraw Facility
Provider" with the Issuer Trustee and the Trust Manager. Pursuant to the terms
of the Redraw Facility Agreement, the Redraw Facility Provider shall be
obligated, subject to the limitations set forth below, to fund the amount of any
Redraws not funded with Gross Principal Collections. To the extent that Gross
Principal Collections are insufficient to fund Redraws (a "Redraw Shortfall")
and amounts are available under the Redraw Facility, the Trust Manager must
direct the Issuer Trustee to draw on the Redraw Facility. Under the Redraw
Facility, the Redraw Facility
 
                                      103
<PAGE>
Provider agrees to make advances to the Issuer Trustee up to the limit from time
to time (the "Redraw Limit") or any lesser amount as agreed between the Redraw
Facility Provider, the Issuer Trustee and the Trust Manager. At the Closing
Date, the Redraw Limit is expected to be A$30,000,000. The Redraw Limit may not
be increased without written confirmation from the Rating Agencies that the
increase would not result in a downgrading or withdrawal of the rating for the
Offered Notes then outstanding.
 
    The Redraw Facility Provider may revoke the Redraw Facility at any time
immediately on giving notice to the Issuer Trustee and the Trust Manager.
 
DRAWINGS
 
    In the event of a Redraw Shortfall on any Collection Determination Date, the
Trust Manager must direct the Issuer Trustee to draw down on the Redraw Facility
for an amount (a "Redraw Advance") equal to the lesser of the Redraw Shortfall
and the Available Redraw Amount (as defined herein). A drawing may only be made
under the Redraw Facility on account of a Redraw Shortfall.
 
    "Available Redraw Amount" means at any time the greater of: (a) the Redraw
Limit at such time less (i) the Principal Outstanding at that time; and (ii) the
Carryover Redraw Charge Offs at that time; and (b) zero. The sum of all Redraw
Advances outstanding on any particular date less the Carryover Redraw Charge
Offs at that time shall be the "Principal Outstanding."
 
    A drawing may only be made by the Issuer Trustee delivering to the Redraw
Facility Provider a duly completed drawdown notice signed by the Issuer Trustee;
provided, however, that each of the following conditions precedent to drawing
are met.
 
CONDITIONS PRECEDENT TO DRAWING
 
    The obligations of the Redraw Facility Provider to make available each
Redraw Advance are subject to the conditions precedent that:
 
    (1) no event of default has occurred and is continuing under the Redraw
Facility at the date of the relevant drawdown notice and the relevant drawdown
date or will result from the provision of the Redraw Advance; and
 
    (2) the representations and warranties by the Issuer Trustee in the Redraw
Facility are true as at the date of the relevant drawdown notice and the
relevant drawdown date as though they had been made at that date in respect of
the facts and circumstances then subsisting.
 
DRAW FEE
 
    With respect to any Redraw Advance made by the Redraw Facility Provider, a
fee (the "Draw Fee") will accrue from day to day on the amount of each such
Redraw Advance from the date of its advance at a rate equal to the Bank Bill
Rate plus a margin (which varies depending on how long the Redraw Advance is
outstanding), calculated on the basis of the actual number of days elapsed since
the advance and a year of 365 days. The Draw Fee shall be payable on each
Payment Date and on termination of the Redraw Facility. To the extent any Draw
Fee is not paid, the amount of such unpaid Draw Fee will be capitalized and
interest will accrue on any such unpaid Draw Fee. On any date, the "Bank Bill
Rate" shall be the rate calculated by taking the rates quoted on the Reuters
Screen BBSW Page at approximately 10:00 am, Sydney time, on that date for each
Reference Bank so quoting (but not fewer than five) as being the mean buying and
selling rate for a bill (which for the purpose of this definition means a bill
of exchange of the type specified for the purpose of quoting on the Reuters
Screen BBSW Page) having a tenor of 90 days eliminating the highest and lowest
mean rates and taking the average of the remaining mean rates and then (if
necessary) rounding the resultant figure upwards to four decimal places. If on
any date fewer than five Reference Banks have quoted rates on the Reuters Screen
BBSW Page, the rate for that date shall be calculated as above by taking the
rates otherwise quoted by five of the Reference Banks on application by
 
                                      104
<PAGE>
the parties for such a bill of the same tenor. If in respect of any date the
rate for that date cannot be determined in accordance with the foregoing
procedures then the rate for that date shall mean such rate as is agreed between
the Trust Manager and Westpac having regard to comparable indices then
available, provided that on the first day of any first Interest Period as it
relates to a Class of Notes the Bank Bill Rate shall be an interpolated rate
calculated with reference to the tenor of the relevant period.
 
AVAILABILITY FEE
 
    For so long as the Redraw Facility exists, a fee (the "Availability Fee")
shall accrue daily from the date of the Redraw Facility on the Available Redraw
Amount, which Availability Fee is payable on each Payment Date and on
termination of the Redraw Facility. The Availability Fee is calculated on the
actual number of days elapsed and a year of 365 days.
 
REPAYMENT OF REDRAW ADVANCES
 
    To the extent a Redraw Advance has been made and has not been repaid to the
Redraw Facility Provider, the amount of such unreimbursed Redraw Advance is
repayable on the following Payment Date and on the date of termination of the
Redraw Facility, to the extent that there are funds available for such payment.
It is not an event of default if the Issuer Trustee does not have funds
available to repay the full amount of the unreimbursed Redraw Advance on the
following Payment Date.
 
EVENTS OF DEFAULT UNDER THE REDRAW FACILITY
 
    It is an event of default under the Redraw Facility (whether or not such
event is within the control of the Issuer Trustee) if:
 
        (1) an amount is available for payment to the Redraw Facility Provider
    under the Redraw Facility, and the Issuer Trustee does not pay that amount
    within 10 Business Days of its due date;
 
        (2) an Insolvency Event occurs in relation to the Trust;
 
        (3) an Insolvency Event occurs in relation to the Issuer Trustee, and a
    successor trustee of the Trust is not appointed within 30 days of that
    Insolvency Event;
 
        (4) the Termination Date occurs in relation to the Trust; or
 
        (5) an event of default (as defined in the Security Trust Deed) occurs
    and any action is taken to enforce the security interest under the Security
    Trust Deed over the assets of the Trust (including appointing a receiver or
    receiver and manager or selling any of those assets).
 
    With respect to the Issuer Trustee (in its personal capacity and as trustee
of a Trust), the Trust Manager, the Servicer, Westpac or a Mortgage Insurer
(each a "relevant corporation"), an "Insolvency Event" will occur upon the
happening of any of the following events:
 
        (1) an administrator of the relevant corporation is appointed;
 
        (2) except for the purpose of a solvent reconstruction or amalgamation:
 
           (i) an application or an order is made, proceedings are commenced, a
       resolution is passed or proposed in a notice of proceedings or an
       application to a court or other steps (other than frivolous or vexatious
       applications, proceedings, notices and steps) are taken for:
 
               (a) the winding up, dissolution or administration of the relevant
           corporation; or
 
               (b) the relevant corporation to enter into an arrangement,
           compromise or composition with or assignment for the benefit of its
           creditors or a class of them; or
 
           (ii) the relevant corporation ceases, suspends or threatens to cease
       or suspend the conduct of all or substantially all of its business or
       disposes of or threatens to dispose of substantially all of its assets;
       or

        (3) the relevant corporation is, or under applicable legislation is
    taken to be, unable to pay its debts (other than as the result of a failure
    to pay a debt or claim the subject of a good faith dispute) or stops or
    suspends or threatens to stop or suspend payment of all or a class of its
    debts (except, in the case of the Issuer Trustee where this occurs in
    relation to another trust of which it is the trustee);
 
        (4) a receiver, receiver and manager or administrator is appointed (by
    the relevant corporation or by any other person) to all or substantially all
    of the assets and undertaking of the relevant corporation or any part
    thereof (except, in the case of the Issuer Trustee where this occurs in
    relation to another trust of which it is the trustee); or
 
        (5) anything analogous to an event referred to in paragraphs (1) to (4)
    (inclusive) or having substantially similar effect, occurs with respect to
    the relevant corporation.
 
    The "Termination Date" with respect to the Trust shall be the earlier to
occur of:
 
        (1) the date which is 80 years after the date of creation of the Trust;
 
        (2) the termination of the Trust under statute or general law;
 
        (3) full and final enforcement by the Security Trustee of its rights
    under the Security Trust Deed after the occurrence of an Event of Default;
    or
 
        (4) at any time after all creditors of the Trust have been repaid in
    full and the Issuer Trustee and the Trust Manager agree that no further
    Notes are proposed to be issued by the Issuer Trustee in relation to the
    Trust, the Business Day immediately following that date.
 
CONSEQUENCES OF OCCURRENCE OF EVENTS OF DEFAULT
 
    At any time after an event of default (whether or not it is continuing) the
Redraw Facility Provider may do all or any of the following:
 
        (1) by notice to the Issuer Trustee and the Trust Manager declare all
    moneys actually or contingently owing under the Redraw Facility immediately
    due and payable, and the Issuer Trustee must immediately pay the Principal
    Outstanding together with accrued interest and fees and all such other
    moneys; and
 
        (2) by notice to the Issuer Trustee and the Trust Manager cancel the
    Redraw Limit with effect from any date specified in that notice.
 
TERMINATION OF THE REDRAW FACILITY
 
    The Redraw Facility will terminate on the earliest of the following:
 
        (1) the date on which the Issuer Trustee enters into a replacement
    Redraw Facility;
 
        (2) one month after the Class A Notes, the Class B Notes, the RFSs and
    the Class A RFS Notes have been redeemed in full in accordance with the
    Master Trust Deed and the Series Notice;
 
        (3) following an event of default under the Redraw Facility, the date on
    which the Redraw Facility Provider declares the Redraw Facility terminated;
 
        (4) the date on which the Issuer Trustee has cancelled the Redraw Limit
    in full. The Issuer Trustee may cancel all or part of the Redraw Limit on
    not less than five Business Days irrevocable notice to the Redraw Facility
    Provider;
 
        (5) the date which is one year after the Maturity Date;
 
        (6) the date on which the Redraw Limit is cancelled in full by the
    Redraw Facility Provider; or
 
        (7) the date on which Westpac Securitisation Management Pty Limited
    retires or is removed as Trust Manager under the Master Trust Deed.
 
                                      106
<PAGE>
    The Redraw Limit may be also be reduced in part by the Redraw Facility
Provider by giving notice to the Issuer Trustee and the Trust Manager. Such a
reduction will not result in a termination of the Redraw Facility.
 
ISSUANCE OF REDRAW FUNDING SECURITIES ("RFS")
 
    If on a Collection Determination Date:
 
        (1) Gross Principal Collections for the Collection Period preceding that
    Collection Determination Date and all amounts available to be drawn under
    the Redraw Facility are insufficient to fund Redraws made during that
    Collection Period; or
 
        (2) the Principal Outstanding under the Redraw Facility divided by the
    Redraw Limit, expressed as a percentage, is equal to or greater than 90% of
    the Redraw Limit;
 
    then the Trust Manager may give the Issuer Trustee a direction to issue a
series of RFSs (the "RFS Series").
 
CONDITION PRECEDENT TO THE ISSUE OF RFSS
 
    Notwithstanding the requirements referred to above, before giving a
direction for the issue of an RFS Series the Trust Manager must confirm with the
Rating Agencies that the issue will not result in the downgrading or withdrawal
of the rating of any Offered Note.
 
RFS CLASS A NOTES
 
    If, on the fifth Collection Determination Date following the date on which
an RFS Series was issued, the RFS Stated Amount for all RFSs in that RFS Series
has not been reduced to zero, each of those outstanding RFSs will convert to an
"RFS Class A Note." Such RFS Class A Note will:
 
        (1) have an Initial Invested Amount equal to the RFS Initial Invested
    Amount of the converted RFS;
 
        (2) have an Invested Amount equal to the RFS Invested Amount of that
    Note when it was an RFS at the date of conversion;
 
        (3) have a Stated Amount equal to the RFS Stated Amount of the RFS at
    the date of conversion;
 
        (4) be denominated in Australian dollars;
 
        (5) receive all payments of principal and interest denominated in
    Australian dollars;
 
        (6) have an Interest Rate calculated by reference to the Bank Bill Rate,
    not "USD-LIBOR-BBA";
 
        (7) be evidenced by a notation in a register maintained by the Issuer
    Trustee; and
 
        (8) have a Margin equal to the margin under the Class A Notes.
 
    "Margin" means: (1) in the case of Class A Notes,    % and in the case of
the Class B Notes,    %; (2) in the case of any RFSs, the margin inscribed in
the register maintained by the Issuer Trustee in relation to those RFSs on their
issue date; and (3) in the case of any RFS Class A Note, the Margin for the
Class A Notes plus the spread under the Currency Swaps.
 
FORM OF THE RFSS AND THE RFS CLASS A NOTES
 
    The RFSs and the RFS Class A Notes will be evidenced by a notation in a
register maintained by the Issuer Trustee, denominated in Australian dollars and
will be issued in Australia to Australian resident investors only. The total
issue amount of RFS Class A Notes (if any) will be determined by the amount of
RFSs (if any) issued during the term of the Offered Notes. The RFSs and RFS
Class A Notes are not offered hereby.
 
                                      107
<PAGE>
INTEREST PAYABLE ON THE RFSS AND THE RFS CLASS A NOTES
 
    Commencing on the issue date of an RFS or the conversion date of an RFS
Class A Note, Interest is payable monthly in arrears on each RFS and RFS Class A
Note to the person whose name is registered under the Master Trust Deed and the
Series Notice as the holder of the RFS or RFS Class A Note, until the Maturity
Date or until the Stated Amount of the RFS or RFS Class A Note is reduced to
zero (whichever is earlier). "Interest", with respect to an RFS or an RFS Class
A Note, shall be equal to the interest accrued on the Invested Amount for such
RFS or RFS Class A Note at a rate equal to the Bank Bill Rate on the first day
of that Interest Period plus the Margin for the RFS or RFS Class A Note, during
the period from the subsequent Payment Date to the day preceding the Payment
Date, calculated on the actual number of days in the related Interest Period
over 365.
 
    Payments to the holders of RFSs and the holders of RFS Class A Notes will be
in Australian dollars. Payments of Interest on the RFSs and the RFS Class A
Notes are PARI PASSU with respect to Interest payable on the Class A Notes and
rank ahead of Interest payable on the Class B Notes.
 
SUBORDINATION OF CLASS B NOTES; PRIORITY OF PAYMENT OF PRINCIPAL TO RFSS
 
    The Class A Noteholders, the holders of RFSs (if any), the holders of RFS
Class A Notes (if any) and the Redraw Facility Provider will have the benefit of
the subordination of the Class B Notes. That is, to the extent that there is a
loss on a Housing Loan which is not satisfied by a claim (or deemed claim) under
a Mortgage Insurance Policy, by amounts recoverable by the Issuer Trustee from
an Approved Seller or the Servicer, or by the application of Excess Available
Income, the amount of that loss will be allocated to the Class B Notes, reducing
the Stated Amount of the Class B Notes until their Stated Amount is zero. The
amount of any remaining loss will then be allocated PARI PASSU, between the
Class A Notes, the RFSs (if any), the RFS Class A Notes (if any) and the Redraw
Facility, reducing the Stated Amount of the Class A Notes, the RFSs (if any) and
the RFS Class A Notes (if any) until their Stated Amount is zero and reducing
the Principal Outstanding under the Redraw Facility until it is zero. For
further details see "-- Application of Principal Charge Offs" above. Payments of
principal on the RFSs will be made prior to payments of principal to the Offered
Noteholders and the holders of the RFS Class A Notes.
 
SUBSTITUTION OF HOUSING LOANS
 
    The Trust Manager may substitute a housing loan from a WST warehouse trust
for a Housing Loan in the Trust. For a housing loan in a WST trust to be
eligible for substitution for a Housing Loan, the housing loan in the other WST
trust must have a maturity date not later than the date which is one year before
the Maturity Date of the Notes, have similar product features to one or more of
the Housing Loans, have an Unpaid Balance within A$30,000 of the Unpaid Balance
of the Housing Loan for which it is being substituted and must otherwise be
suitable for substitution in the Trust Manager's sole and absolute discretion.
The Trust Manager may take into account the geographic location of the
properties securing the Housing Loan and the substituted housing loan. In
addition, the Unpaid Balance of all housing loans acquired by the Trust must be
less than the Unpaid Balance of the Housing Loans transferred to the WST
warehouse trust. The Trust Manager may not substitute a housing loan unless it
has received written confirmation from the Rating Agencies that the substitution
will not result in the downgrade or withdrawal of the rating given to the
Offered Notes. In addition, if the Unpaid Balance of the Housing Loan removed
from the Trust is greater than the Unpaid Balance of the substituted housing
loan, the WST warehouse trust must pay the Issuer Trustee the Substitution Net
Transfer Amount (Principal) and Substitution Net Transfer Amount (Income) with
respect to such Housing Loan.
 
PRESCRIPTION
 
    An Offered Note shall become void in its entirety unless surrendered for
payment within ten years of the Relevant Date in respect of any payment thereon
the effect of which would be to reduce the Stated
 
                                      108
<PAGE>
Amount of such Offered Note to zero. After the date on which an Offered Note
becomes void in its entirety, no claim may be made in respect of it.
 
    The "Relevant Date" means the date on which a payment first becomes due but,
if the full amount of the money payable has not been received in New York City
by the Principal Paying Agent or the Note Trustee on or prior to that date, it
means the date on which, the full amount of such money having been so received,
notice to that effect is duly given in accordance with the terms of the Offered
Notes.
 
CLEAN-UP OFFER
 
    If at any time the aggregate Housing Loan Principal, expressed as a
percentage of the aggregate Housing Loan Principal as of the Cut-Off Date, is
less than 10%, then, if instructed by the Trust Manager, the Seller Trustee may
repurchase, on the following Payment Date, the equitable title to the Housing
Loans held by the Trust for an amount equal to the Unpaid Balance (in the case
of performing Housing Loans) or the Fair Market Value (in the case of
non-performing Housing Loans). The proceeds of sale will be applied by the
Issuer Trustee to repay moneys owing to Noteholders at that time in accordance
with the priorities for applying payments of Interest and principal between the
Classes of Notes.
 
REDEMPTION OF THE NOTES
 
    If an Event of Default occurs under the Security Trust Deed while the
Offered Notes are outstanding, the Security Trustee may (subject, in certain
circumstances, to the prior written consent of the Note Trustee in accordance
with the provisions of the Security Trust Deed), (and will if so directed by the
Note Trustee alone where it is the only Voting Mortgagee, or, otherwise by a
resolution of 75% of the Voting Mortgagees) enforce the security created by the
Security Trust Deed. That enforcement can include the sale of some or all of the
Housing Loans. There is no guarantee that the Security Trustee will be able to
sell the Housing Loans for their then Unpaid Balance. Accordingly, the Security
Trustee may not be able to realize the full value of the Housing Loans and this
may have an impact upon the Issuer Trustee's ability to repay all amounts
outstanding in relation to the Notes.
 
    Any proceeds from the enforcement of the security will be applied in
accordance with the order of priority of payments as set out in the Security
Trust Deed. See "SECURITY FOR THE NOTES-- Priorities Under the Security Trust
Deed."
 
    If the Trust terminates while Notes are outstanding, Westpac has a right of
first refusal to acquire the Housing Loans. The price to be paid by Westpac for
performing and non-performing Housing Loans must not be less than their Fair
Market Value. In the case of performing loans, the Issuer Trustee is required to
offer to sell them to Westpac under its right of first refusal for their then
Unpaid Balance. The "Unpaid Balance" of a Housing Loan, means the sum of (a) the
unpaid principal amount of that Housing Loan; and (b) the unpaid amount of all
finance charges, interest payments and other amounts accrued on or payable under
or in connection with that Housing Loan or the related Mortgage or other rights
relating to the Housing Loan. Where the Fair Market Value of a Housing Loan is
less than its then Unpaid Balance, its acquisition by Westpac will be subject to
prior approval by 75% of the votes of all Noteholders. This is because in such
circumstances there may be a shortfall in the amount available to the Issuer
Trustee to fully repay all amounts outstanding in relation to the Notes. The
Servicer will determine whether a Housing Loan is performing or non-performing.
 
WITHHOLDING OR TAX DEDUCTIONS
 
    All payments in respect of the Offered Notes will be made without
withholding or tax deduction for, or on account of, any present or future taxes,
duties or charges of whatsoever nature unless the Issuer Trustee or any Paying
Agent is required by applicable law to make any such payment in respect of the
Offered Notes subject to any withholding or deduction for, or on account of, any
present or future taxes, duties or charges of whatsoever nature. In the event
that the Issuer Trustee or the Paying Agent (as the case may be) shall make such
payment after such withholding or deduction has been made, it shall account
 
                                      109
<PAGE>
to the relevant authorities for the amount so required to be withheld or
deducted. Neither the Issuer Trustee nor any Paying Agent will be obliged to
make any additional payments to holders of the Offered Notes in respect to that
withholding or deduction.
 
REDEMPTION OF THE OFFERED NOTES FOR TAXATION OR OTHER REASONS
 
    If the Trust Manager satisfies the Issuer Trustee and the Note Trustee
immediately prior to giving the notice referred to below that either (i) on the
next Payment Date the Issuer Trustee would be required to deduct or withhold
from any payment of principal or interest in respect of the Offered Notes any
amount for or on account of any present or future taxes, duties, assessments or
governmental charges of whatever nature imposed, levied, collected, withheld or
assessed by the Commonwealth of Australia or any of its political sub-divisions
or any of its authorities or (ii) the total amount payable in respect of
interest in relation to the Housing Loans for a Collection Period ceases to be
receivable (whether or not actually received) by the Issuer Trustee during such
Collection Period by reason of any present or future taxes, duties, assessments
or governmental charges of whatever nature imposed, levied, collected, withheld
or assessed by the Commonwealth of Australia or any of its political
sub-divisions or any of its authorities, the Issuer Trustee must, when so
directed by the Trust Manager (at any time at the Trust Manager's option)
(provided that the Issuer Trustee will be in a position on such Payment Date to
discharge (and will so certify to the Issuer Trustee and the Note Trustee) all
its liabilities in respect of such Class and any amounts required under the
Security Trust Deed to be paid in priority to or PARI PASSU with such Class)
upon having given not more than 60 nor less than 30 days' notice to the
Noteholders of such Class redeem all, but not some, of such Class at their
Invested Amount (or at the option of the holders of 75% of the aggregate
Invested Amount of such Class, at their Stated Amount), together with accrued
interest to the date of redemption on any subsequent Payment Date, provided that
the holders of 75% of the aggregate Invested Amount of such Class may elect, and
shall notify the Issuer Trustee and the Trust Manager, that they do not require
the Issuer Trustee to redeem such Class of Notes in the circumstances described
above. All amounts ranking prior to or PARI PASSU with respect to a Class of
Notes must be redeemed concurrently with such Class. Thus the Class B Notes may
not be redeemed unless the Class A Notes are also redeemed.
 
TERMINATION OF THE TRUST
 
TERMINATION EVENTS
 
    The Trust shall continue until, and shall terminate on the later of: (i) its
respective Termination Date; (ii) the date on which the Trust Assets have been
sold or realized upon (which such sale shall be completed within 180 days after
the Termination Date of the Trust so far as reasonably practicable and
reasonably commercially viable); and (iii) the date on which the Issuer Trustee
ceases to hold any Housing Loans or Mortgages in relation to the Trust.
 
REALIZATION UPON TRUST ASSETS
 
    On the termination of the Trust, subject to Westpac's right of first refusal
outlined below, the Issuer Trustee must sell and realize the assets of the Trust
within 180 days. During the 180 day period, the Housing Loans, if performing,
must not be sold for less than their Unpaid Balance and in the case of non-
performing Housing Loans, for less than their Fair Market Value. The Issuer
Trustee may not sell any performing Housing Loan, within the 180 day period, for
less than its Fair Market Value without the consent of the holders of 75% of the
aggregate Invested Amount of the relevant Class of Notes. The Servicer will
determine whether a Housing Loan is performing or non-performing.
 
APPROVED SELLER'S RIGHT OF FIRST REFUSAL
 
    As soon as practical after the Termination Date of the Trust, the Trust
Manager will direct the Issuer Trustee to offer (by written notice to Westpac)
irrevocably to extinguish in favor of Westpac, or if the Issuer Trustee has
perfected its title, to equitably assign to Westpac, its entire right, title and
interest in and to the
 
                                      110
<PAGE>
Housing Loans, and related Mortgages (if any) for their Unpaid Balance (for
performing Housing Loans) and their Fair Market Value (for non-performing
Housing Loans). If the Fair Market Value of a Housing Loan is less than its
Unpaid Balance, the sale requires the approval of the holders of 75% of the
votes of all Noteholders.
 
    The Issuer Trustee is not entitled to sell any Housing Loans unless Westpac
has failed to accept the offer within 180 days after the occurrence of the
Termination Date by paying to the Issuer Trustee, within 180 days, the purchase
price.
 
DISTRIBUTION
 
    After deducting expenses, the Trust Manager shall direct the Issuer Trustee
to distribute the proceeds of realization of the assets of the Trust in
accordance with the cashflow allocation methodology set out above, and in
accordance with any directions given to it by the Trust Manager.
 
    If all Notes relating to the Trust have been fully redeemed and the Trust's
creditors paid in full, the Issuer Trustee may distribute all or part of the
Trust Assets to the relevant Beneficiary.
 
TRUST ACCOUNTS
 
    The Issuer Trustee will establish and maintain under the Master Trust Deed
bank accounts with an Approved Bank, consisting of the "Collection Account" and
the US$ Account (collectively, the "Trust Accounts"). Each bank account shall be
opened by the Issuer Trustee in its name and in its capacity as trustee of the
Trust. No bank account shall be used for any purpose other than for the Trust
and in accordance with the Master Trust Deed.
 
    The Trust Manager shall have the discretion and duty to recommend or to
propose in writing to the Issuer Trustee, the manner in which any moneys forming
part of the Trust shall be invested in Authorized Investments and what
purchases, sales, transfers, exchanges, collections, realizations or alterations
of Trust Assets shall be effected and when and how the same should be effected.
It is the role of the Issuer Trustee to give effect to all such recommendations
or proposals of the Trust Manager. Each investment of moneys on deposit in the
Trust Accounts shall be in Authorized Investments that will mature not later
than the Business Day preceding the applicable monthly Payment Date. "Authorized
Investments" consist of the following: (a) Housing Loans, Mortgages and other
related securities, (b) cash, (c) bonds, debentures, stock or treasury bills of
the Commonwealth of Australia or the Government of any State or Territory of the
Commonwealth; (d) debentures or stock of any public statutory body constituted
under the law of the Commonwealth of Australia or of any State of the
Commonwealth where the repayment of the principal is secured and the interest
payable thereon is guaranteed by the Commonwealth or any State or Territory of
the Commonwealth; (e) notes or other securities of the Commonwealth of Australia
or the Government of any State or Territory of the Commonwealth; (f) (i)
deposits with, or the acquisition of certificates of deposit (whether
negotiable, convertible or otherwise), issued by, a bank which carries on
business in Victoria and New South Wales; (ii) bills of exchange which at the
time of acquisition have a remaining term to maturity of not more than 200 days,
accepted or endorsed by a bank which carries on business in Victoria and New
South Wales, which, in each case, has either: (A) the highest short-term rating
available to be given by the Rating Agencies; or (B) if such investment has a
maturity of 30 days or less and does not exceed 20% of the total Invested Amount
of all relevant Notes on the date of the investment, a short-term rating of
A-1+/P-1/F-1+ by S&P, Moody's and Fitch, respectively; and (g) any other assets
of a class of assets that are both: (i) prescribed for the purposes of
sub-paragraph (iv) of the definition of a "pool of mortgages" in section 84FA(1)
of the Stamp Duties Act, 1920 of New South Wales, or are otherwise included
within that definition of "pool of mortgages"; and (ii) declared by order of the
Governor in Council of Victoria and published in the Victorian Government
Gazette to be assets for purposes of Subdivision 17A of the Stamps Act, 1958 of
Victoria or are otherwise included within sub-paragraph (b)(ii) of the
definition of "pool of mortgages" in section 137NA of that Act. No Authorized
Investment may have a maturity which is later than the Maturity Date of the
outstanding Notes.

    On each Determination Date, the Trust Manager will, in respect of the
Collection Period ending before that Determination Date, deliver to the
Principal Paying Agent on behalf of the Issuer Trustee, a report (the
"Noteholder's Report") containing the following information:

    The Notes will be registered in the name of a nominee of DTC and will not be
registered in the names of the beneficial owners or their nominees. As a result,
unless and until Definitive Notes are issued in the limited circumstances
described under "--Definitive Notes" below, beneficial owners will not be
recognized by the Issuer Trustee as Noteholders, as that term is used in the
Master Trust Deed. Hence, until such time, beneficial owners will receive
reports and other information provided for under the Transaction Documents only
if, when and to the extent provided by DTC and its participating organizations.
 
    The Trust Manager will, on or promptly after each Notice Date, prepare and
arrange for the publication on Reuters Screen page WST/SEC9 to WST/SEC10 of
summary pool performance data for the Trust in a format as determined by the
Trust Manager.
 
BOOK-ENTRY REGISTRATION
 
    Each Class of the Offered Notes will be represented by one or more
book-entry Notes (the "Book-Entry Notes"). Persons acquiring beneficial
ownership interests in the Offered Notes ("Note Owners") will hold their Notes
through the Depository Trust Company ("DTC") in the United States, or Cedel or
Euroclear (in Europe) if they are participants of such systems, or indirectly
through organizations which are participants in such systems. The Book-Entry
Notes will be issued in one or more certificates which equal the aggregate
principal balance of each Class of the Offered Notes and will initially be
registered in the name of Cede & Co., the nominee of DTC. Cedel and Euroclear
will hold omnibus positions on behalf of their participants through customers'
securities accounts in Cedel's and Euroclear's names on the books of their
respective depositaries which in turn will hold such positions in customers'
securities accounts in the depositaries' names on the books of DTC. Citibank,
N.A. will act as depositary for Cedel, and Morgan Guaranty Trust Company of New
York will act as depositary for Euroclear (in such capacities, individually, the
"Relevant Depositary" and collectively, the "European Depositaries"). Investors
may hold such beneficial interests in the Book-Entry Notes in minimum
denominations of US$100,000. Except as described below, no person acquiring a
Book-Entry Note (each, a "beneficial owner") will be entitled to receive a
physical certificate representing such Note (a "Definitive Note"). Unless and
until Definitive Notes are issued, it is anticipated that the only "Noteholder"
of each Class of Notes will be Cede & Co., as nominee of DTC. Note Owners will
not be considered holders of the Offered Notes in relation to the Master Trust
Deed. Note Owners are only permitted to exercise their rights indirectly through
participants and DTC.
 
    The Note Owner's ownership of a Book-Entry Note will be recorded on the
records of the brokerage firm, bank, thrift institution or other financial
intermediary (each, a "Financial Intermediary") that maintains the beneficial
owner's account for such purpose. In turn, the Financial Intermediary's
ownership of such Book-Entry Note will be recorded on the records of DTC (or of
a participating firm that acts as agent for the Financial Intermediary, whose
interest will in turn be recorded on the records of DTC, if the beneficial
owner's Financial Intermediary is not a DTC participant and on the records of
Cedel or Euroclear, as appropriate).
 
    Note Owners will receive all distributions of principal of, and interest on,
each Class of Offered Notes from the Issuer Trustee through DTC and DTC
Participants. While the Offered Notes are outstanding (except under the
circumstances described below), under the rules, regulations and procedures
creating and affecting DTC and its operations (the "Rules"), DTC is required to
make book-entry transfers among Participants on whose behalf it acts with
respect to the Offered Notes and is required to receive and transmit
distributions of principal of, and interest on, the Offered Notes. Participants
and indirect participants with whom Note Owners have accounts with respect to
Offered Notes are similarly required to make book-entry transfers and receive
and transmit such distributions on behalf of their respective Note Owners.
Accordingly, although Note Owners will not possess certificates, the Rules
provide a mechanism by which Note Owners will receive distributions and will be
able to transfer their interest.
 
    Note Owners will not receive or be entitled to receive certificates
representing their respective interests (i.e., Definitive Notes) in the Offered
Notes, except under the limited circumstances described
 
                                      113
<PAGE>
below. Unless and until Definitive Notes are issued, Note Owners who are not
Participants may transfer ownership of Offered Notes only through Participants
and indirect participants by instructing such Participants and indirect
participants to transfer Offered Notes, by book-entry transfer, through DTC for
the account of the purchasers of such Offered Notes, which account is maintained
with their respective Participants. Under the Rules and in accordance with DTC's
normal procedures, transfers of ownership of Offered Notes will be executed
through DTC and the accounts of the respective Participants at DTC will be
debited and credited. Similarly, the Participants and indirect participants will
make debits or credits, as the case may be, on their records on behalf of the
selling and purchasing Note Owners.
 
    Because of time zone differences, credits of securities received in Cedel or
Euroclear as a result of a transaction with a Participant will be made during
subsequent securities settlement processing and dated the Business Day following
the DTC settlement date. Such credits or any transactions in such securities
settled during such processing will be reported to the relevant Euroclear or
Cedel Participants on such Business Day. Cash received in Cedel or Euroclear as
a result of sales of securities by or through a Cedel Participant (as defined
below) or Euroclear Participant (as defined below) to a DTC Participant will be
received with value on the DTC settlement date but will be available in the
relevant Cedel or Euroclear cash account only as of the Business Day following
settlement in DTC.
 
    Transfers between Participants will occur in accordance with DTC Rules.
Transfers between Cedel Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
    Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through Cedel
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance with DTC Rules on behalf of the relevant European international
clearing system by the Relevant Depositary; however, such cross market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in such system in accordance
with its rules and procedures and within its established deadlines (European
time). The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to the
Relevant Depositary to take action to effect final settlement on its behalf by
delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same day funds settlement applicable to
DTC. Cedel Participants and Euroclear Participants may not deliver instructions
directly to the European Depositaries.
 
    DTC, which is a New York-chartered limited purpose trust company, performs
services for its participants, some of which (and/or their representatives) own
DTC. In accordance with its normal procedures, DTC is expected to record the
positions held by each DTC participant in the Book-Entry Notes, whether held for
its own account or as a nominee for another person. In general, beneficial
ownership of Book-Entry Notes will be subject to the rules, regulations and
procedures governing DTC and DTC participants as in effect from time to time.
 
    Cedel is incorporated under the laws of Luxembourg as a professional
depository. Cedel holds securities for its participating organizations ("Cedel
Participants") and facilitates the clearance and settlement of securities
transactions between Cedel Participants through electronic book-entry changes in
accounts of Cedel Participants, thereby eliminating the need for physical
movement of certificates. Transactions may be settled in Cedel in any of 28
currencies, including United States dollars. Cedel provides to its Cedel
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally-traded securities and securities
lending and borrowing. Cedel interfaces with domestic markets in several
countries. As a professional depository, Cedel is subject to regulation by the
Luxembourg Monetary Institute. Cedel participants are recognized financial
institutions around the world, including underwriters, securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations. Indirect access to Cedel is also available to others, such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Cedel Participant, either directly or indirectly.
 
                                      114

    Euroclear was created in 1968 to hold securities for its participants
("Euroclear Participants") and to clear and settle transactions between
Euroclear Participants through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled in any of 32 currencies, including United
States dollars. Euroclear includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements for cross-market transfers with DTC
described above. Euroclear is operated by the Brussels, Belgium office of Morgan
Guaranty Trust Company of New York (the "Euroclear Operator"), under contract
with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the
"Cooperative"). All operations are conducted by the Euroclear Operator, and all
Euroclear securities clearance accounts and Euroclear cash accounts are accounts
with the Euroclear Operator, not the Cooperative. The Cooperative establishes
policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants
include banks (including central banks), securities brokers and dealers and
other professional financial intermediaries. Indirect access to Euroclear is
also available to other firms that clear through or maintain a custodial
relationship with a Euroclear Participant, either directly or indirectly.
 
    The Euroclear Operator is the Belgian branch of a New York banking
corporation which is a member bank of the Federal Reserve System. As such, it is
regulated and examined by the Board of Governors of the Federal Reserve System
and the New York State Banking Department, as well as the Belgian Banking
Commission.
 
    Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System and applicable Belgian law
(collectively, the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities and
cash from Euroclear, and receipts of payments with respect to securities in
Euroclear. All securities in Euroclear are held on a fungible basis without
attribution of specific certificates to specific securities clearance accounts.
The Euroclear Operator acts under the Terms and Conditions only on behalf of
Euroclear Participants, and has no record of or relationship with persons
holding through Euroclear Participants.
 
    Distributions on the Book-Entry Notes will be made on each Payment Date by
the Principal Paying Agent to DTC. DTC will be responsible for crediting the
amount of such payments to the accounts of the applicable DTC participants in
accordance with DTC's normal procedures. Each DTC participant will be
responsible for disbursing such payments to the beneficial owners of the
Book-Entry Notes that it represents and to each Financial Intermediary for which
it acts as agent. Each such Financial Intermediary will be responsible for
disbursing funds to the beneficial owners of the Book-Entry Notes that it
represents.
 
    Under a book-entry format, beneficial owners of the Book-Entry Notes may
experience some delay in their receipt of payments, since such payments will be
forwarded by the Principal Paying Agent to Cede & Co. Distributions with respect
to the Offered Notes held through Cedel or Euroclear will be credited to the
cash accounts of Cedel Participants or Euroclear Participants in accordance with
the relevant system's rules and procedures, to the extent received by the
Relevant Depositary. Such distributions will be subject to tax reporting in
accordance with relevant United States tax laws and regulations. Because DTC can
only act on behalf of Financial Intermediaries, the ability of a beneficial
owner to pledge Book-Entry Notes to persons or entities that do not participate
in the Depository system, or otherwise take actions in respect of such
Book-Entry Notes, may be limited due to the lack of physical certificates for
such Book-Entry Notes. In addition, issuance of the Book-Entry Notes in
book-entry form may reduce the liquidity of such Offered Notes in the secondary
market since certain potential investors may be unwilling to purchase the
Offered Notes for which they cannot obtain physical certificates.
 
    Quarterly and annual reports on the Trust will be provided to Cede & Co., as
nominee of DTC, and may be made available by Cede & Co. to beneficial owners
upon request, in accordance with the rules, regulations and procedures creating
and affecting the Depository, and to the Financial Intermediaries to whose DTC
accounts the Book-Entry Notes of such beneficial owners are credited.
 
                                      115
<PAGE>
    DTC has advised the Note Trustee that, unless and until Definitive Notes are
issued, DTC will take any action permitted to be taken by the holders of the
Book-Entry Notes under the Note Trust Deed only at the direction of one or more
Financial Intermediaries to whose DTC accounts the Book-Entry Notes are
credited, to the extent that such actions are taken on behalf of Financial
Intermediaries whose holdings include such Book-Entry Notes. Cedel or the
Euroclear Operator, as the case may be, will take any other action permitted to
be taken by an Offered Noteholder under the Transaction Documents on behalf of a
Cedel Participant or Euroclear Participant only in accordance with its relevant
rules and procedures and subject to the ability of the Relevant Depositary to
effect such actions on its behalf through DTC. DTC may take actions, at the
direction of the related Participants, with respect to some Offered Notes which
conflict with actions taken with respect to other Offered Notes.
 
    Although DTC, Cedel and Euroclear have agreed to the foregoing procedures in
order to facilitate transfers of Offered Notes among participants of DTC, Cedel
and Euroclear, they are under no obligation to perform or continue to perform
such procedures and such procedures may be discontinued at any time.
 
    Neither the Issuer Trustee, the Servicer nor the Note Trustee will have any
responsibility for any aspect of the records relating to or payments made on
account of beneficial ownership interests of the Book-Entry Notes held by Cede &
Co., as nominee for DTC, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
DEFINITIVE NOTES
 
    The Offered Notes of each Class will be issued in definitive form to the
Note Owners of such Class or their nominees ("Definitive Notes"), rather than to
the Depository or its nominee, only if (i) the Trust Manager advises the
Principal Paying Agent in writing that the Depository is no longer willing or
able to discharge properly its responsibilities as Depository with respect to
the Offered Notes of such Class, or the Depository or its successor ceases to
carry on business and the Trust Manager is unable to locate a qualified
successor, (ii) the Issuer Trustee, at the direction of the Trust Manager
advises the Principal Paying Agent in writing that the book-entry system through
the Depository is or is to be terminated or (iii) an Event of Default has
occurred, and Note Owners representing not less than a majority of the aggregate
Invested Amount of such Class advise the Principal Paying Agent and the Issuer
Trustee through the Participants and the Depository in writing that the
continuation of a book-entry system through the Depository is no longer in the
best interest of the Note Owners of such Class.
 
   
    Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Depository is required to notify all Participants of
the availability through the Depository of Definitive Notes. Upon surrender by
the Depository of the definitive certificate representing the Offered Notes of
the affected Class and instructions for registration, the Trustee will execute
and the Principal Paying Agent will authenticate the Offered Notes of such Class
as Definitive Notes, and thereafter the Trustee will recognize the Note Owners
of such Definitive Notes as Offered Noteholders under the Transaction Documents.
    
 
    Distributions of principal and interest on the Offered Notes will be made by
the Principal Paying Agent directly to Offered Noteholders in accordance with
the procedures set forth herein and in the Master Trust Deed, Series Notice, the
Note Trust Deed and Agency Agreement. Interest payments and any principal
payments on each Payment Date will be made to Offered Noteholders in whose names
the Definitive Notes were registered at the close of business on the related
Record Date. Distributions will be made by check mailed to the address of such
Noteholder as it appears on the register maintained by the Principal Paying
Agent. The final payment, on any Offered Note, however, will be made only upon
presentation and surrender of such Note at the office or agency specified in the
notice of final distribution to Offered Noteholders. The Trustee will provide
such notice to registered Noteholders.
 
    Definitive Notes will be transferable and exchangeable at the offices of the
transfer agent and registrar, which initially will be the Principal Paying Agent
(in such capacity, the "Transfer Agent and Registrar"). No service charge will
be imposed for any registration of transfer or exchange, but the Transfer
 
                                      116
<PAGE>
Agent and Registrar may require payment of a sum sufficient to cover any tax or
other governmental charge imposed in connection therewith. The Transfer Agent
and Registrar will not be required to register the transfer or exchange of
Definitive Notes for the period from the Record Date preceding the due date for
any payment to the Payment Date with respect to such Definitive Notes.
 
MODIFICATION OF MASTER TRUST DEED, SERIES NOTICE AND THE NOTE TRUST DEED WITHOUT
  NOTEHOLDER CONSENT
 
    The Issuer Trustee, the Trust Manager, the Servicer (with respect to the
Master Trust Deed and the Series Notice) and the Note Trustee (with respect to
the Note Trust Deed) may by way of supplemental deed alter, add to or modify the
Master Trust Deed, the Series Notice and the Note Trust Deed so long as such
alteration, addition or modification was effected upon consent of the
Noteholders or Beneficiaries (see "--Modification of Master Trust Deed, Series
Notice and the Note Trust Deed With Noteholder Consent" below) or is:
 
        (a) to correct a manifest error or ambiguity or is of a formal,
    technical or administrative nature only;
 
        (b) necessary to comply with the provisions of any law or regulation or
    with the requirements of any Australian governmental agency;
 
        (c) appropriate or expedient as a consequence of an amendment to any law
    or regulation or altered requirements of any Government Agency (including,
    without limitation, an alteration, addition or modification which is
    appropriate or expedient as a consequence of the enactment of a statute or
    regulation or an amendment to any statute or regulation or ruling by the
    Australian Commissioner or Deputy Commissioner of Taxation or any
    governmental announcement or statement, in any case which has or may have
    the effect of altering the manner or basis of taxation of trusts generally
    or of trusts similar to any of the Trusts); or
 
       (d) in the opinion of the Issuer Trustee desirable to enable the
    provisions of the Master Trust Deed to be more conveniently, advantageously,
    profitably or economically administered or is otherwise desirable for any
    reason (including to give effect, in the Trust Manager's reasonable opinion,
    to an allocation of expenses).
 
MODIFICATION OF MASTER TRUST DEED, SERIES NOTICE AND THE NOTE TRUST DEED WITH
  NOTEHOLDER CONSENT
 
    Where in the reasonable opinion of the Issuer Trustee a proposed alteration,
addition or modification to the Master Trust Deed, the Series Notice and the
Note Trust Deed (except an alteration, addition or modification referred to in
"--Modification of Master Trust Deed, Series Notice and the Note Trust Deed
Without Noteholder Consent" above) is prejudicial or likely to be prejudicial to
the interests of the Noteholders or a Class of Noteholders or the Beneficiaries
such alteration, addition or modification may only be effected by the Issuer
Trustee with the prior consent of the holders of 75% of the aggregate Invested
Amount of the Notes, the Class A Notes or the Class B Notes (as the case may be)
or with the prior written consent of the Beneficiaries (as the case may be).

MEETINGS OF VOTING MORTGAGEES
 
    The Security Trust Deed contains provisions for convening meetings of the
Voting Mortgagees to, INTER ALIA, enable the Voting Mortgagees to direct or
consent to the Security Trustee taking or not taking certain actions under the
Security Trust Deed, for example, to enable the Voting Mortgagees to direct the
Security Trustee to enforce the Security Trust Deed.
 
    For so long as the amounts outstanding under the Offered Notes are 75% or
more of all amounts secured by the Security Trust Deed, the Note Trustee may
direct the Security Trustee to do any act or thing which the Security Trustee is
required to do, or may only do, at the direction of an Extraordinary Resolution
of the Voting Mortgagees.
 
    Neither the Security Trustee nor the Trust Manager may call a meeting of
Voting Mortgagees without the Note Trustee's consent, if the amounts outstanding
under the Notes are 75% or more of all amounts secured by the Security Trust
Deed.
 
VOTING OF CLASS A NOTEHOLDERS; MODIFICATION; CONSENTS; WAIVER
 
    The Note Trust Deed contains provisions for the Class A Noteholders to
consider any matter affecting their interests. In general, the holders of a
majority of the aggregate Invested Amount of the Class A Notes may take or
consent to any action permitted to be taken by Class A Noteholders under the
Note Trust Deed. Notwithstanding the foregoing, the consent of holders of 75% of
the aggregate Invested Amount of the Class A Notes shall be required to (i)
direct the Note Trustee to direct the Security Trustee to enforce the security
under the Note Trust Deed, (ii) override any waiver by the Note Trustee of a
breach of any provisions of the Transaction Documents or an Event of Default,
(iii) alter, add, or modify the terms and conditions of the Class A Notes or the
provisions of any of the Transaction Documents if such alteration, addition or
modification is, in the opinion of the Note Trustee, materially prejudicial or
likely to be materially prejudicial to the Offered Noteholders as a whole or the
Class A Noteholders, which shall include any modification to the date of
maturity of the Class A Notes, or a modification which would have the effect of
postponing any day for payment of interest in respect of any Class A Notes,
reducing or cancelling the amount of principal payable in respect of any Class A
Notes or the rate of interest applicable to any Class A Notes or altering the
percentage of the aggregate Invested Amount required to consent to any action or
altering the currency of payment of any Class A Notes or an alteration of the
date or priority of redemption of the Class A Notes (any such modification being
referred to below as a "Basic Terms Modification"). The Note Trust Deed contains
provisions limiting the powers of the Class B Noteholders, INTER ALIA, to
request or direct the Note Trustee to take any action that would be materially
prejudicial to the interests of the Class A Noteholders. Except in certain
circumstances, the Note Trust Deed imposes no such limitations on the powers of
the Class A Noteholders, the exercise of which will be binding on the Class B
Noteholders, irrespective of the effect on the Class B Noteholders' interests.
Any action taken by the requisite percentage of the Invested Amount of the Class
A Noteholders shall be binding on all Class A Noteholders (both present and
future).
 
    Pursuant to the terms of the Note Trust Deed, the Note Trustee may agree,
without the consent of the Class A Noteholders, among other things, (i) to any
modification (except a Basic Terms Modification) of, or to the waiver or
authorization of any breach or proposed breach of the Class A Notes (including
the Conditions), or any of the Transaction Documents which is not, in the
opinion of the Note Trustee materially prejudicial to the interests of the Class
A Noteholders or (ii) to any modification of the Class A Notes (including the
Conditions, or any of the Transaction Documents which, in the Note Trustee's
opinion, is to correct a manifest error or is of a formal, minor or technical
nature or necessary to comply with any law or regulation. The Note Trustee may
also, without the consent of the Class A Noteholders, determine that any Event
of Default or any condition, event or act which with the giving of notice and/or
lapse of time and/or the issue of a certificate would constitute an Event of
Default shall not, or shall not subject to specified conditions, be treated as
such. Any such modification, waiver, authorization or determination shall be
binding on the Class A Noteholders and, unless the Note Trustee agrees
otherwise,
 
                                      118
<PAGE>
any such modification shall be notified to the Class A Noteholders as specified
in the Transaction Documents as soon as practicable thereafter.
 
VOTING OF CLASS B NOTEHOLDERS; MODIFICATIONS; CONSENTS; WAIVER
 
    The Note Trust Deed contains provisions for the Class B Noteholders to
consider any matter affecting their interests. In general, the holders of a
majority of the aggregate Invested Amount of the Class B Notes may take or
consent to any action permitted to be taken by Class B Noteholders under the
Note Trust Deed. Notwithstanding the foregoing, the consent of holders of 75% of
the aggregate Invested Amount of the Class B Notes shall be required to (i)
direct the Note Trustee to direct the Security Trustee to enforce the security
under the Note Trust Deed, (ii) override any waiver by the Note Trustee of a
breach of any provisions of the Transaction Documents or an Event of Default,
(iii) alter, add, or modify the terms and conditions of the Class B Notes or the
provisions of any of the Transaction Documents if such alteration, addition or
modification is, in the opinion of the Note Trustee, materially prejudicial or
likely to be materially prejudicial to the Offered Noteholders as a whole or the
Class B Noteholders, which shall include any modification to the date of
maturity of the Class B Notes, or a modification which would have the effect of
postponing any day for payment of interest in respect of any Class B Notes,
reducing or cancelling the amount of principal payable in respect of any Class B
Notes or the rate of interest applicable to any Class B Notes or altering the
percentage of the aggregate Invested Amount required to consent to any action or
altering the currency of payment of any Class B Notes or an alteration of the
date or priority of redemption of the Class B Notes (any such modification being
referred to below as a "Basic Terms Modification"). The Note Trust Deed contains
provisions limiting the powers of the Class B Noteholders, INTER ALIA, to
request or direct the Note Trustee to take any action that would be materially
prejudicial to the interests of the Class A Noteholders. Except in certain
circumstances, the Note Trust Deed imposes no such limitations on the powers of
the Class A Noteholders, the exercise of which will be binding on the Class B
Noteholders, irrespective of the effect on their interests. Any action taken by
the requisite percentage of Invested Amount of the Class B Noteholders shall be
binding on all Class B Noteholders (both present and future).
 
    Pursuant to the terms of the Note Trust Deed, the Note Trustee may agree,
without the consent of the Class B Noteholders; among other things (i) to any
modification (except a Basic Terms Modification) of; or to the waiver or
authorization of any breach or proposed breach of the Class B Notes (including
the Conditions with respect to the Class B Notes), or any of the Transaction
Documents which is not, in the opinion of the Note Trustee materially
prejudicial to the interests of the Class B Noteholders or (ii) to any
modification of the Class B Notes (including the Conditions with respect to the
Class B Notes, or any of the Transaction Documents which, in the Note Trustee's
opinion, is to correct a manifest error or is of a formal, minor or technical
nature or necessary to comply with any law or regulation. The Note Trustee may
also, without the consent of the Class B Noteholders, determine that any Event
of Default or any condition, event or act which with the giving of notice and/or
lapse of time and/or the issue of a certificate would constitute an Event of
Default shall not, or shall not subject to specified conditions, be treated as
such. Any such modification, waiver, authorization or determination shall be
binding on the Class B Noteholders and, unless the Note Trustee agrees
otherwise, any such modification shall be notified to the Class B Noteholders as
specified in the Transaction Documents as soon as practicable thereafter.
 
EVENTS OF DEFAULT; RIGHTS UPON EVENT OF DEFAULT
 
    An "Event of Default" under the Security Trust Deed will occur if:
 
        (1) the Issuer Trustee fails to pay any Interest within 10 Business Days
    of the Payment Date on which the Interest was due to be paid to Class A
    Noteholders, Class B Noteholders, holders of RFSs or holders of RFS Class A
    Notes;
 
        (2) the Issuer Trustee fails to pay any other amount owing to Class A
    Noteholders, Class B Noteholders, holders of RFSs, holders of RFS Class A
    Notes or any other Mortgagee (as defined in
 
                                      119
<PAGE>
    the Security Trust Deed) within 10 Business Days of the due date for payment
    (or within any applicable grace period agreed with the relevant Mortgagee or
    where the Mortgagee is a Noteholder with the Note Trustee);
 
        (3) the Issuer Trustee fails to perform or observe any other provisions
    (other than the obligations referred to in paragraphs (1) and (2)) of a
    Transaction Document where such failure will have a material and adverse
    effect on the amount of any payment to be made to any Noteholder or will
    materially and adversely affect the timing of such payment, and that default
    (if in the opinion of the Security Trustee capable of remedy (that opinion,
    being subject in certain circumstances to the approval of the Note Trustee
    in accordance with the provisions of the Security Trust Deed)) is not
    remedied within 30 days (or such longer period as may be specified in the
    notice, that longer period having been approved by the Note Trustee, for so
    long as amounts outstanding under the Offered Notes are 75% or more of the
    Secured Moneys) after written notice from the Security Trustee requiring the
    failure to be remedied;
 
        (4) an Insolvency Event occurs relating to the Issuer Trustee (in its
    personal capacity or as trustee of the Trust);
 
        (5) the charge created by the Security Trust Deed is not or ceases to be
    a first ranking charge over the Trust Assets, or any other obligation of the
    Issuer Trustee (other than as mandatorily preferred by law) ranks ahead of
    or PARI PASSU with any of the moneys secured by the Security Trust Deed;
 
        (6) any security interest over the Trust Assets is enforced;
 
        (7) all or any part of any Transaction Document (other than the Redraw
    Facility or the Swap Agreements) is terminated or is or becomes void,
    illegal, invalid, unenforceable or of limited force and effect, or a party
    becomes entitled to terminate, rescind or avoid all or part of any
    Transaction Document (other than the Underwriting Agreement, the Redraw
    Facility or the Swap Agreements); or
 
        (8) without the prior consent of the Security Trustee (that consent
    being subject in certain circumstances to the prior written consent of the
    Note Trustee in accordance with the provisions of the Security Trust Deed),
    (i) the Trust is wound up, or the Issuer Trustee is required to wind up the
    Trust under the Master Trust Deed or applicable law, or the winding up of
    the Trust commences; (ii) the Trust is held or is conceded by the Issuer
    Trustee not to have been constituted or to have been imperfectly
    constituted; or (iii) unless another trustee is appointed to the Trust under
    the Transaction Documents, the Issuer Trustee ceases to be authorized under
    the Trust to hold the property of the Trust in its name and to perform its
    obligations under the Transaction Documents.
 
    If an Event of Default occurs and is continuing, the Note Trustee shall
deliver to each Offered Noteholder notice of such Event of Default within 90
days of the date that the Note Trustee became aware of such Event of Default,
provided that, except in the case of a default in payment of Interest and
principal on the Offered Notes, the Note Trustee may withhold such notice if and
so long as it determines in good faith that withholding the notice is in the
interests of the Offered Noteholders.
 
ENFORCEMENT OF THE SECURITY TRUST DEED
 
    The Security Trustee must promptly convene a meeting of the Voting
Mortgagees after it receives notice, or has actual knowledge of, an Event of
Default. The Security Trustee may waive (such waiver, being subject to the prior
written consent of the Note Trustee in accordance with the provisions of the
Security Trust Deed), an Event of Default before it is required to convene a
meeting of Mortgagees if that Event of Default is not (in the opinion of the
Security Trustee) materially prejudicial to the Mortgagees' interests.
 
                                      120
<PAGE>
    At the meeting, the Voting Mortgagees must vote by Extraordinary Resolution
(being a resolution passed at a duly convened meeting by a majority consisting
of not less than 75% of the votes capable of being cast by Voting Mortgagees
present in person or by proxy or by written resolution signed by all of the
Voting Mortgagees) on whether to direct the Security Trustee to:
 
        (1) declare the charge to be enforceable;
 
        (2) declare all Secured Moneys (including amounts outstanding under the
    Notes plus accrued and unpaid interest) to be immediately due and payable;
 
        (3) crystalize the floating charge created under the Security Trust Deed
    in relation to any or all of the Mortgaged Property; and/or
 
        (4) appoint a receiver over the Trust Assets or itself exercise the
    powers that a receiver would otherwise have under the Security Trust Deed.
 
    The Security Trustee cannot exercise the powers referred to above unless
directed by an Extraordinary Resolution in the manner outlined above. The
Security Trustee is not obligated to act unless it obtains an indemnity from the
Voting Mortgagees, and is put in funds to the extent to which it may become
liable for the relevant enforcement actions.
 
    For so long as the Note Trustee is the only Voting Mortgagee it may direct
the Security Trustee to do any act which the Security Trustee is required to do,
or may only do, at the direction of an Extraordinary Resolution of Voting
Mortgagees. Neither the Security Trustee nor the Trust Manager may call a
meeting of Voting Mortgagees while the Note Trustee is the only Voting
Mortgagee, unless the Note Trustee otherwise consents. The Note Trustee will be
the only Voting Mortgagee for so long as the amounts outstanding under the
Offered Notes are 75% or more of all amounts secured by the Security Trust Deed.
 
    Upon the occurrence of an Event of Default: (i) if the Note Trustee is the
only Voting Mortgagee; and (ii) if the Note Trustee directs the Security Trustee
to enforce the charge (whether directed to do so by Class A Noteholders or as
the Note Trustee determines on behalf of the Class A Noteholders), the Security
Trustee shall enforce the charge as if directed to do so by an Extraordinary
Resolution of Voting Mortgagees.
 
    No Mortgagee is entitled to enforce the charge under the Security Trust
Deed, or appoint a receiver or otherwise exercise any power conferred by any
applicable law on charges, otherwise than in accordance with the Security Trust
Deed.
 
    "Voting Mortgagee" means:
 
    (1) for so long as the amounts outstanding under the Class A Notes and the
Class B Notes are 75% or more of all Secured Moneys, the Note Trustee alone; and
 
    (2) at any other time: (i) the Note Trustee, acting on behalf of the Offered
Noteholders under the Note Trust Deed and the Security Trust Deed; and (ii) each
other Mortgagee under the Security Trust Deed (other than the Offered
Noteholders).
 
    Subject to being indemnified in accordance with the Security Trust Deed, the
Security Trustee shall take all action necessary to give effect to any direction
by the Note Trustee where it is the only Voting Mortgagee or to any
Extraordinary Resolution of the Voting Mortgagees and shall comply with all
directions given by the Note Trustee where it is the only Voting Mortgagee or
contained in or given pursuant to any Extraordinary Resolution of the Voting
Mortgagees in accordance with the Security Trust Deed.
 
    No Noteholder is entitled to enforce the Security Trust Deed or to appoint
or cause to be appointed a receiver to any of the assets secured by the Security
Trust Deed or otherwise to exercise any power conferred by the terms of any
applicable law on charges except as provided in the Security Trust Deed.
 
                                      121
<PAGE>
    If any of the Class A Notes remains outstanding and are due and payable
otherwise than by reason of a default in payment of any amount due on the Class
A Notes, the Note Trustee must not vote under the Security Trust Deed to, or
otherwise direct the Security Trustee to, dispose of the Mortgaged Property
unless either:
 
       (i) a sufficient amount would be realized to discharge in full all
    amounts owing to the Class A Noteholders, and any other amounts payable by
    the Issuer Trustee ranking in priority to or PARI PASSU with the Class A
    Notes; or
 
       (ii) the Note Trustee is of the opinion, reached after considering at any
    time and from time to time the advice of a merchant bank or other financial
    adviser selected by the Note Trustee, that the cash flow receivable by the
    Issuer Trustee (or the Security Trustee under the Security Trust Deed) will
    not (or that there is a significant risk that it will not) be sufficient,
    having regard to any other relevant actual, contingent or prospective
    liabilities of the Issuer Trustee, to discharge in full in due course all
    the amounts referred to in paragraph (i). The Class B Notes are subject to
    similar constraints.
 
    Neither the Note Trustee nor the Security Trustee will be liable for any
decline in the value, nor any loss realized upon any sale or other dispositions
made under the Security Trust Deed, of any Mortgaged Property or any other
property which is charged to the Security Trustee by any other person in respect
of or relating to the obligations of the Issuer Trustee or any third party in
respect of the Issuer Trustee or the Notes or relating in any way to the
Mortgaged Property. Without limitation, neither the Note Trustee nor the
Security Trustee shall be liable for any such decline or loss directly or
indirectly arising from its acting, or failing to act, as a consequence of an
opinion reached by it.
 
    The Note Trustee shall not be bound to vote under the Security Trust Deed,
or otherwise direct the Security Trustee under the Security Trust Deed or to
take any proceedings, actions or steps under, or any other proceedings pursuant
to or in connection with the Security Trust Deed, the Note Trust Deed, any Class
A Notes, unless directed or requested to do so (i) by an Extraordinary
Resolution of the Class A Noteholders or the Class B Noteholders, as
appropriate; or (ii) in writing by the holders of at least one-quarter of the
aggregate Invested Amount of the Class A Notes and then only if the Note Trustee
is indemnified to its satisfaction against all action, proceedings, claims and
demands to which it may render itself liable and all costs, charges, damages and
expenses which it may incur by so doing.
 
    Only the Security Trustee may enforce the provisions of the Security Trust
Deed and neither the Note Trustee nor any holder of an Offered Note, is entitled
to proceed directly against the Issuer Trustee to enforce the performance of any
of the provisions of the Security Trust Deed or the Offered Notes (including the
Conditions).
 
    The rights, remedies and discretion of the Class A Noteholders and the Class
B Noteholders under the Security Trust Deed including all rights to vote or give
instructions or consent can only be exercised by the Note Trustee on behalf of
the Class A Noteholders or the Class B Noteholders, as applicable, in accordance
with the Security Trust Deed. The Security Trustee may rely on any instructions
or directions given to it by the Note Trustee as being given on behalf of the
Class A Noteholders, from time to time and need not enquire whether the Note
Trustee or the Noteholders from time to time have complied with any requirements
under the Note Trust Deed or as to the reasonableness or otherwise of the Note
Trustee. The Security Trustee is not obliged to take any action, give any
consent or waiver or make any determination under the Security Trust Deed
without being directed to do so by the Note Trustee or by Extraordinary
Resolution of the Voting Mortgagees in accordance with the Security Trust Deed.
 
    Upon enforcement of the security created by the Security Trust Deed, the net
proceeds thereof may be insufficient to pay all amounts due on redemption to the
Noteholders. The proceeds from enforcement (which will not include amounts
required by law to be paid to the holder of any prior ranking security interest,
the proceeds of or amounts credited to the collateral account under the
Liquidity Facility Agreement and payable to the Liquidity Facility Provider and
the proceeds of cash collateral lodged with and payable to a Swap Provider or
other provider of a Support Facility) will be applied in the order of
 
                                      122
<PAGE>
priority as set out in the Security Trust Deed (see "SECURITY FOR THE
NOTES--Priorities under the Security Trust Deed"). Any claims of the Noteholders
remaining after realization of the security and application of the proceeds as
aforesaid shall, except in certain limited circumstances, be extinguished.
 
    See "SECURITY FOR THE NOTES" for a description of the Security Trust Deed
and the order of priorities for the proceeds from the enforcement of the
Security Trust Deed.

    (including obtaining all appropriate authorizations) to ensure that it is

Noteholders, the Beneficiaries (as defined in the Master Trust Deed) the holders
of RFSs (if any) and the holders of RFS Class A Notes (if any) or other

    (5) The Issuer Trustee will open and operate certain bank accounts in
accordance with the Master Trust Deed and the Series Notice.

in which event the Issuer Trustee will be obligated to appoint a successor
trustee. The Issuer Trustee may also remove the Note Trustee if the Note Trustee
ceases to be eligible to continue as such under the Note Trust Deed or if the
Note Trustee becomes insolvent or ceases its business. In addition, holders of
75% of the aggregate Invested Amount of the Class A Notes or, if the Class A
Notes are no longer outstanding, the Class B Notes may require the Issuer
Trustee to remove the Note Trustee. In such circumstances and others set forth
in the Note Trust Deed, the Issuer Trustee will be obligated to appoint a
successor note trustee. Any resignation or removal of the Note Trustee and
appointment of a successor note trustee will not become effective until
acceptance of the appointment by a successor note trustee and confirmation by

sentence. If the Note Trustee is required by the Transaction Documents or
Offered Notes to have regard to the interests of the Class A Noteholders and the
Class B Noteholders and where, in the opinion of the Note Trustee, there is a
conflict between the interests of the Class A Noteholders and the interests of
the Class B Noteholders, the Note Trustee shall have regard only to the
interests of the Class A Noteholders despite anything to the contrary in the
Transaction Documents. In such an event, the Class B Noteholders shall have no
claim against the Note Trustee for doing so.
 
GOVERNING LAW
 
    The Notes and the Transaction Documents (other than the Security Trust Deed

accordance with, the laws of New South Wales, Australia. The Security Trust Deed
is governed by, and shall be construed in accordance with the laws of the

                     DESCRIPTION OF THE SERVICING AGREEMENT
 
GENERAL
 
    Under the Servicing Agreement, TMC will be appointed as the initial Servicer
of the Housing Loans and custodian of the Relevant Documents relating to the
Housing Loans and Mortgages. The following section contains a summary of the
material terms of the Servicing Agreement. The summary does not
 
                                      124
<PAGE>
purport to be complete and is subject to the provisions of the Servicing
Agreement, which has been filed as an exhibit to the Registration Statement.
 
SERVICING
 
    The Servicer manages and services the Housing Loans in accordance with the
Servicing Agreement. To the extent not provided in the Servicing Agreement, the
Servicer shall manage and service the Housing Loans in accordance with the
Procedures Manual as that is interpreted and applied by the Servicer in the
ordinary course of its business. "Procedures Manual" means, in relation to the
Housing Loans, those policies and procedures of Westpac or the Servicer (as the
case may be) relating to the origination, management and enforcement of the
Housing Loans as those policies and procedures are amended in accordance with
the Servicing Agreement and applied from time to time in Westpac's or the
Servicer's ordinary course of business (as the case may be). To the extent not
covered by the Servicing Agreement or the Procedures Manual, the Servicer
manages and services the Housing Loans by exercising the degree of diligence and
care expected of an appropriately qualified servicer of the relevant financial
products and custodian of documents. All acts of the Servicer in servicing the
Housing Loans in accordance with the relevant procedures manual are binding on
the Issuer Trustee.
 
POWERS
 
    Subject to the servicing standards set forth above and the limitations set
forth below, the Servicer has the express power, among other things, to the
extent such action will not cause an Adverse Effect (that is, an event which
will materially and adversely affect the amount of any payment to be made to any
Noteholder, or will materially and adversely affect the timing of such payment):
 
        (1) to waive any fees and break costs which may be collected in the
    ordinary course of servicing the Housing Loans or arrange the rescheduling
    of interest due and unpaid following a default under any Housing Loans;
 
        (2) in its discretion, to waive any right in respect of any Housing
    Loans and Mortgages in the ordinary course of servicing the Housing Loans
    and Mortgages (including in accordance with its normal collection
    procedures); and
 
        (3) to grant an extension of maturity beyond 30 years from the date any
    Housing Loan that relates to a Mortgage was made, when required to do so by
    law or a government agency. The restriction on granting extensions that will
    not have an Adverse Effect shall not apply where the extension is required
    by law or a governmental agency.
 
DELEGATION BY THE SERVICER
 
    The Servicer is entitled to delegate its duties under the Servicing
Agreement. The Servicer at all times remains liable for servicing the Housing
Loans and the acts or omissions of any delegate.
 
SERVICER UNDERTAKINGS
 
    The Servicer has undertaken, among other things, the following:

    Borrowers and mortgagors, registering transfers, delivering documents to the
    Issuer Trustee and taking other action required to perfect title.

    the relevant Housing Loan and the related Mortgage to the extent it
    determines to be appropriate.
 
        (5) Act in accordance with the terms of any Mortgage Insurance Policies,
    not do or omit to do anything which could be reasonably expected to
    prejudicially affect or limit its rights or the rights of the Issuer Trustee
    under or in respect of a Mortgage Insurance Policy, and promptly make a
    claim under any Mortgage Insurance Policy when it is entitled to do so and
    notify the Trust Manager when each such claim is made.
 
        (6) It will not consent to the creation or existence of any security
    interest in favor of a third party in relation to any Mortgaged Property
    which would rank before or PARI PASSU with the relevant Housing Loan and
    Mortgage or allow the creation or existence of any other security interest
    in the Mortgaged Property unless priority arrangements are entered into with
    such third party under which the third party acknowledges that the Housing
    Loan and the Mortgage ranks ahead in priority to the third party's security
    interest on enforcement for an amount not less than the Unpaid Balance of
    the Housing Loan plus such other amount as the Servicer determines in
    accordance with the Procedures Manual or its ordinary course of business.
 
        (7) It will not, except as required by law, release a Borrower or
    otherwise vary or discharge any Housing Loan or Mortgage where it would have
    an Adverse Effect.

    permits, approvals, exemptions, filings and registrations as may be required
    under any applicable law in order properly to service the Housing Loans and
    Mortgages and to perform or comply with its obligations under the Servicing
    Agreement.
 
        (12) It will notify: (i) the Issuer Trustee and the Trust Manager of any
    event which it reasonably believes is likely to have an Adverse Effect
    promptly after becoming aware of such event; and (ii) the Trust Manager of
    anything else which the Trust Manager reasonably requires regarding any
    proposed modification to any Housing Loan or Mortgage.
 
        (13) It will provide information reasonably requested by the Issuer
    Trustee or the Trust Manager, with respect to all matters relating to the
    Trust and the assets of the Trust, and the Issuer Trustee or the Trust
    Manager believes reasonably necessary for it to perform its obligations
    under the Transaction Documents, and upon reasonable notice and at
    reasonable times permit the Issuer Trustee to enter the premises and inspect
    the data and records in relation to the Trust and the Relevant Documents.

                                      126
<PAGE>
    any Housing Loan or Mortgage and to perform or comply with its obligations
    under the Servicing Agreement; and comply with all Laws in connection with
    its ownership of any Housing Loans and Mortgages where failure to do so
    would have an Adverse Effect.
 
        (2) It will cooperate with the Servicer in relation to the performance
    by the Servicer of its duties under the Servicing Agreement, including,
    without limitation, in relation to the enforcement of any Housing Loan or
    Mortgage.
 
        (3) If a material default occurs in respect to a Mortgage, it will take
    such action as the Servicer directs it to take in accordance with the
    Servicing Agreement.
 
        (4) It will act in accordance with the terms of any Mortgage Insurance
    Policies, and not do or omit to do anything which could be reasonably

    under or in respect of a Mortgage Insurance Policy to the extent those
    rights relate to a Housing Loan and the Mortgage.
 
        (5) It will not consent to the creation or existence of any security

    interest on enforcement for an amount not less than the Unpaid Balance of
    the Housing Loan plus such other amount as the Servicer determines in
    accordance with the Procedures Manual or its ordinary course of business.
 
        (6) It will not, except as required by law, release a Borrower from any
    amount owing in respect of a Housing Loan or otherwise vary or discharge any
    Housing Loan or Mortgage or enter into any agreement or arrangement which
    has the effect of altering the amount payable in respect of a Housing Loan
    or Mortgage where it would have an Adverse Effect.
 
        (7) It will release any Housing Loan or Mortgage, reduce the amount
    outstanding under or vary the terms of any Housing Loan or grant other
    relief to a Borrower, if required to do so by any law or if ordered to do so
    by a court, tribunal, authority, ombudsman or other entity whose decisions
    are binding on Westpac. If the order is due to Westpac breaching any
    applicable law then Westpac must indemnify the Issuer Trustee for any loss
    the Issuer Trustee may suffer by reason of the order. The amount of the loss
    is to be determined by agreement with the Issuer Trustee or failing this, by
    Westpac's external auditors.

have regard to whether its performance of such services does or does not have
any Adverse Effect. The Servicer may ask the Issuer Trustee or the Trust Manager
if, and may rely upon any statement by the Issuer Trustee or the Trust Manager
that, any action or inaction on its part is reasonably likely to, or will, have
an Adverse Effect. The Servicer shall not be liable for a breach of the
Servicing Agreement, or be liable under any indemnity, in relation to any action
or inaction on its part, where it has been notified by the Issuer Trustee or the
Trust Manager that the action or inaction is not reasonably likely to, or will
not have, an Adverse Effect.
 
                                      127
<PAGE>
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
    The Servicer is entitled to a fee (the "Servicing Fee") for servicing the
Housing Loans, payable in arrears on the Payment Date following the end of the
Collection Period. The Servicing Fee is based on the average daily balance of
Housing Loan Principal during the Collection Period and on the actual number of
days in that Collection Period divided by 365 days.
 
    The Servicer must pay from such fee all expenses incurred in connection with
servicing the Housing Loans except for expenses relating to the enforcement of
any Housing Loan or its related securities, the recovery of any amounts owing
under any Housing Loan or any amount repaid to a liquidator or trustee in
bankruptcy pursuant to any applicable law, binding code, order or decision of
any court, tribunal or the like or based on advice of the Servicer's legal
advisers.
 
SERVICER TRANSFER EVENT AND REMOVAL
 
    The Issuer Trustee may only terminate the Servicer's appointment if the
Issuer Trustee determines that a Servicer Transfer Event has occurred and is
continuing. A "Servicer Transfer Event" is any of the following:
 
        (1) an Insolvency Event occurs with respect to the Servicer;
 
        (2) the Servicer fails to pay any amount within five Business Days of
    receipt of a notice to do so;
 
        (3) the Servicer fails to comply with any of its other obligations under
    any Transaction Document and such action has had, or, if continued will
    have, an Adverse Effect (as determined by the Issuer Trustee) and that
    failure is not remedied within 30 days after the Servicer becomes aware of
    that failure by receipt of notice;
 
        (4) any representation, warranty or certification made by the Servicer
    is incorrect when made and is not waived by the Issuer Trustee or remedied
    to the Issuer Trustee's reasonable satisfaction within 90 days after notice
    from the Issuer Trustee, and the Issuer Trustee determines that breach would
    have an Adverse Effect; or
 
        (5) if it is unlawful for the Servicer to perform the services under the
    Servicing Agreement.
 
    In the event of a Servicer Transfer Event, the Issuer Trustee must, upon
notice to the Trust Manager, the Approved Sellers, Westpac, the Servicer and the
Rating Agencies, terminate the rights and obligations of the Servicer with
immediate effect and appoint an Eligible Servicer. Until an Eligible Servicer is
appointed and that Eligible Servicer agrees to act as the servicer, the Issuer
Trustee shall act as the Servicer and is entitled to the fee for so acting.
 
    Subject to certain limitations, the Servicer has indemnified the Issuer
Trustee against any expense, loss, damage or liability incurred as a result of a
Servicer Transfer Event or a failure by the Servicer to perform its duties under
the Servicing Agreement.
 
RESIGNATION
 
    The Servicer must not resign without first giving three months' notice to
the Rating Agencies, the Trust Manager and the Issuer Trustee. If an Eligible
Servicer has not agreed to act as Servicer by the expiration of that notice
period the Issuer Trustee shall act as Servicer and be entitled to the Servicing
Fee.
 
DOCUMENT CUSTODY
 
GENERAL
 
    The Servicer will be responsible for custody of the Relevant Documents on
behalf of the Issuer Trustee. The Servicer must hold those documents as
custodian at the direction of the Issuer Trustee in
 
                                      128
<PAGE>
accordance with its standard safekeeping practices and in the same manner and to
the same extent that it holds similar documents for Westpac. The Servicer will
hold custody of the Relevant Documents in accordance with procedures contained
in the Servicing Agreement. The procedures include the following: (i) keeping
the Relevant Documents for Housing Loans in the Mortgage Pool separate from
other documents; (ii) maintaining reports on movements of the Relevant
Documents; and (iii) being able to locate security packets containing the
Relevant Documents.
 
    The Servicer will be audited on an annual basis (or more regularly if any
audit gives an adverse finding) in relation to its custodial procedures,
identification of documents, security and tracking systems.
 
TERMINATION OF SERVICER AS DOCUMENT CUSTODIAN
 
    If any of the following occurs:
 
        (1) the Servicer does not comply with the requirements of the Servicing
    Agreement to the satisfaction of the auditor, and a further audit also
    results in an adverse finding by the auditor;
 
        (2) the long term credit rating of the holding company of the Servicer
    is downgraded:
 
        (i) below BBB by Standard & Poor's;
 
        (ii) below Baa2 by Moody's; or
 
       (iii) below BBB by Fitch;
 
        (3) the Servicer is in default under a servicing agreement between it
    and any other person, and by reason of the default that other person removes
    any documents in the Servicer's custody under the servicing agreement where
    that person would otherwise not have been entitled to do so; or
 
        (4) a Servicer Transfer Event occurs and is subsisting,
 
then the Servicer must deliver the Relevant Documents to, or at the direction
of, the Issuer Trustee. If the Servicer does not do so within 10 Business Days
(or such longer period as the Trustee permits), then the Issuer Trustee must
enter the premises where the Relevant Documents are kept, take possession of and
remove the Relevant Documents. If the Issuer Trustee does not have possession of
the documents within that period it must lodge caveats in relation to and/or
take all other action it considers necessary to protect its interests.

                             THE LIQUIDITY FACILITY
 
    The following section contains a summary of the material terms of the
Liquidity Facility. The summary does not purport to be complete and is subject
to the provisions of the Liquidity Facility, a form of which has been filed as
an exhibit to the Registration Statement.
 
GENERAL DESCRIPTION
 
    Under the Liquidity Facility, the Liquidity Facility Provider agrees to make
advances to the Issuer Trustee for the purpose of funding certain income
shortfalls in the Trust, up to an aggregate amount being the lesser of:
 
   
        (1) A$79,000,000;
    
 
        (2) the Unpaid Balance of all Performing Loans at that date; and
 
        (3) any lesser amount as is agreed in writing between the Liquidity
    Facility Provider, the Issuer Trustee, the Trust Manager and the Rating
    Agencies for each class of Notes,
 
as reduced or cancelled under the Liquidity Facility (the "Liquidity Limit").
 
    A "Performing Loan" at any date is a Housing Loan which is not Delinquent or
has been Delinquent for less than 90 consecutive days, or if it has been
Delinquent for 90 or more consecutive days was insured under a Mortgage
Insurance Policy at the date of the Liquidity Facility on or before the Closing
Date.
 
    A Housing Loan is "Delinquent" if the related Borrower fails to pay any
amount due on the related due date. Delayed payments arising from agreed payment
holidays based on early repayments, or from maternity or paternity leave
repayment reductions will not, by themselves, lead to a Housing Loan being
Delinquent.
 
LIQUIDITY DRAWS
 
    If the Trust Manager determines on any Collection Determination Date that
the Available Income of the Trust plus Principal Draws for the Collection Period
relating to that Collection Determination Date is insufficient to meet Total
Payments of the Trust (a "Liquidity Shortfall"), then the Trust Manager must
direct the Issuer Trustee to request a drawing under the Liquidity Facility to
apply towards the Liquidity Shortfall. The drawing will (subject to certain
assumptions as to payment) be the lesser of the Liquidity Shortfall and the
difference between the Liquidity Limit and the aggregate of all outstanding
amounts under the Liquidity Facility (the "Available Liquidity Amount"). A
drawing may only be made by a duly completed drawdown notice signed by an
authorized signatory of the Issuer Trustee.
 
CONDITIONS PRECEDENT TO A LIQUIDITY DRAW
 
    A drawing may only be made under the Liquidity Facility (a "Liquidity Draw")
if (among other things) no event of default (see "--Events of Default" below)
subsists at the date of the relevant drawdown notice and the relevant drawdown
date or will result from the provision of the Liquidity Draw.
 
DEPOSIT INTO A COLLATERAL ACCOUNT
 
    If at any time the Liquidity Facility Provider's short term credit rating is
less than A-1+ from Standard & Poor's, P-1 from Moody's or F-1+ from Fitch, the
Liquidity Facility Provider must within five Business Days or such longer period
as the Rating Agencies confirm will not result in a downgrade, withdrawal or
 
                                      130
<PAGE>
qualification of the Offered Notes, deposit into an account held in the name of
the Issuer Trustee (the "Collateral Account") an amount equal to the Available
Liquidity Amount at that time.
 
    If and for so long as the Liquidity Facility Provider has a short term
credit rating of not lower than A-1 from Standard & Poor's, P-1 from Moody's and
F-1 from Fitch, the Collateral Account shall be maintained with the Liquidity
Facility Provider.
 
    If at any time the short term credit rating of the bank holding the
Collateral Account is less than A-1 from Standard & Poor's, P-1 from Moody's or
F-1 from Fitch then the balance of the Collateral Account, and all amounts
standing to the credit of the Collateral Account, must (subject to certain
limited restrictions) within five Business Days (or such longer period as the
Rating Agencies agree) be transferred to a bank with a short term credit rating
from Standard & Poor's of not lower than A-1+, not lower than P-1 from Moody's
and not lower than F-1+ from Fitch.
 
    If the short term credit rating of the Liquidity Facility Provider is not
less than A-1 from Standard & Poor's, P-1 from Moody's and F-1 from Fitch, and
the total of the credit balance of the Collateral Account with the Liquidity
Facility Provider plus the amount of all short term investments of the Issuer
Trustee is greater than 20% of the Total Invested Amount, then so much of the
credit balance of the Collateral Account as is necessary for the 20% threshold
not to be breached must (subject to certain limited restrictions) be deposited
with a bank with a short term credit rating from Standard & Poor's of not lower
than A-1+ and not lower than P-1 from Moody's and not lower than F-1+ from
Fitch.
 
    Withdrawals from a Collateral Account are restricted to, among other things,
making a Liquidity Draw, paying financial institutions duty and bank account
debit tax (being taxes charged on account transactions) and investing in short
term investments.
 
    All interest accrued on the moneys in the Collateral Account shall belong to
the Liquidity Facility Provider. If the Liquidity Facility Provider's short term
credit rating is upgraded to not lower than A-1+ from Standard & Poor's, P-1
from Moody's and F-1+ from Fitch, then the balance in the Collateral Account
must be repaid within five Business Days to the Liquidity Facility Provider and
any advances under the Liquidity Facility thereafter will be made directly from
the Liquidity Facility Provider in the normal course of business.
 
INTEREST ON LIQUIDITY DRAWS
 
    Interest is payable to the Liquidity Facility Provider on the principal
amount drawn under the Liquidity Facility. This interest is payable at the Bank
Bill Rate plus a margin, calculated on days elapsed and a year of 365 days.
Interest is payable on each Payment Date and on repayment of a drawing. Unpaid
interest will capitalize, and interest accrues on any unpaid interest.
 
COMMITMENT FEE
 
    A commitment fee accrues daily from the date of the Liquidity Facility on
the Available Liquidity Amount, and is payable on each Payment Date and on
termination of the facility.
 
    The commitment fee is calculated on the actual number of days elapsed and a
year of 365 days.
 
REPAYMENT OF LIQUIDITY DRAWINGS
 
    If an amount has been drawn down under the Liquidity Facility, the principal
amount is repayable on the following Payment Date, to the extent that amounts
are available for this purpose under the Series Notice; see "DESCRIPTION OF THE
OFFERED NOTES--Distribution of Total Available Funds" above. It is not an event
of default if the Issuer Trustee does not have funds available to repay the full
amount outstanding on the following Payment Date.
 
                                      131
<PAGE>
EVENTS OF DEFAULT
 
    It is an event of default under the Liquidity Facility (whether or not such
event is within the control of the Issuer Trustee) if:
 
        (1) at any time the Available Liquidity Amount is zero, and the Issuer
    Trustee fails to pay an amount payable by it under the Liquidity Facility
    within 10 Business Days of its due date;
 
        (2) an amount is available for payment to the Liquidity Facility
    Provider under the Liquidity Facility and the Issuer Trustee does not pay
    that amount;
 
        (3) an Insolvency Event occurs in relation to the Trust;
 
        (4) an Insolvency Event occurs in relation to the Issuer Trustee, and a
    successor trustee of the Trust is not appointed within 30 days of that
    Insolvency Event;
 
        (5) the Termination Date occurs in relation to the Trust; or
 
        (6) all or any part of the Liquidity Facility is terminated or is or
    becomes void, illegal, invalid or unenforceable.
 
CONSEQUENCES OF DEFAULT
 
    In addition to rights provided by law or any Transaction Document, at any
time after an event of default has occurred under the Liquidity Facility
(whether or not it is continuing), the Liquidity Facility Provider may do all or
any of the following by notice to the Issuer Trustee and the Trust Manager:
 
        (1) declare all moneys actually or contingently owing at that time
    immediately due and payable, and the Issuer Trustee must immediately pay the
    total amount of all outstanding Liquidity Draws, together with accrued
    interest and fees and all other such moneys; and
 
        (2) cancel the Liquidity Limit with effect from any date specified in
    that notice.
 
TERMINATION
 
    The Liquidity Facility will terminate on the earliest of the following to
occur:
 
        (1) the date on which the Issuer Trustee enters into a replacement
    liquidity facility as previously notified to the Rating Agencies;
 
        (2) one month after the Notes have been redeemed in full in accordance
    with the Master Trust Deed;
 
        (3) following an event of default under the Liquidity Facility, the date
    on which the Liquidity Facility Provider declares the Liquidity Facility
    terminated; and
 
        (4) the date on which the Issuer Trustee has cancelled the Liquidity
    Limit in full.
 
    Cancellation of the Liquidity Limit is conditional on the Rating Agencies
confirming that such cancellation will not result in a downgrade, withdrawal or
qualification of the credit rating assigned by the Rating Agencies to the
Offered Notes.

                       DESCRIPTION OF THE SWAP AGREEMENTS
 
DESCRIPTION OF INTEREST RATE SWAP AGREEMENTS
 
    The following section contains a summary of the material terms of the Swap
Agreements, which the Issuer Trustee will enter into with the Interest Rate Swap
Provider. The summary does not purport to be complete and is subject to the
provisions of the Swap Agreements.
 
FIXED RATE AND VARIABLE RATE BASIS SWAPS
 
    The Issuer Trustee will enter into a Variable Rate Basis Swap and two Fixed
Rate Basis Swaps with Westpac, in its capacity as the provider of the Variable
Rate Basis Swap and Westpac, in its capacity as the provider of the Fixed Rate
Basis Swaps (together the "Interest Rate Swap Provider"). Each swap will be
governed by an ISDA Master Agreement, as amended by a supplementary schedule and
confirmed by a written confirmation. All such documents will be governed by the
laws of the state of New South Wales. See "ORIGINATOR OF THE HOUSING LOANS" for
a description of the Interest Rate Swap Provider.
 
    A Variable Rate Basis Swap will be used to hedge the basis risk between the
floating rate obligations of the Trust (including Interest payable on the Notes)
and the variable rate set, as permitted by the relevant Housing Loan agreements,
at the discretion of Westpac. The Variable Rate Basis Swap will include those
loans with a concessional fixed rate of interest for the first 12 months,
converting to the standard variable rate after that period. The Issuer Trustee
will pay an amount based on the applicable daily weighted average variable
interest rates on Housing Loans with a variable rate and receive the Bank Bill
Rate (as defined herein) plus a fixed margin. The margin is fixed for the life
of the swap and has been set having regard to the ongoing obligations of the
Trust.
 
    Two Fixed Rate Basis Swaps will be used to hedge the basis risk between the
floating rate obligations of the Trust (including Interest payable on the Notes)
and the discretionary fixed rates set by Westpac on the Housing Loans which are
subject to a fixed rate of interest (not including those loans with a
concessional fixed rate of interest for the first 12 months, which converts to
the standard variable rate after that period).
 
    The first Fixed Rate Basis Swap will be used to hedge the basis risk
occurring when Borrowers switch from a variable rate of interest to a Fixed Rate
of interest after the Cut-Off Date. The Issuer Trustee will pay the applicable
daily weighted average Fixed Rate on Housing Loans that have converted to a
Fixed Rate since the Cut-Off Date and the Interest Rate Swap Provider will pay
the Bank Bill Rate plus a fixed margin. The margin is fixed for the life of the
swap and has been set having regard to the ongoing obligations of the Trust.
 
    The second Fixed Rate Basis Swap will be entered into as at the Closing Date
to hedge those Housing Loans subject to a Fixed Rate of interest as of the
Cut-Off Date. The Issuer Trustee will pay the applicable daily weighted average
Fixed Rate on Housing Loans that are Fixed Rate and the Interest Rate Swap
Provider will pay the Bank Bill Rate plus a fixed margin. The margin is fixed
for the life of the swap and has been set based on the actual margin on the
Fixed Rate Housing Loans and the prevailing wholesale market rate existing at or
about the Cut-Off Date.
 
    All Housing Loans being charged a Fixed Rate of interest as of the Cut-Off
Date have a maximum Fixed Rate period of 5 years.
 
DOWNGRADE OF INTEREST SWAP PROVIDER
 
    If there is a downgrading of the Interest Rate Swap Provider's short term
debt rating below A-1+, A2 or F-1+ by either Standard & Poor's, Moody's or
Fitch, respectively, the Interest Swap Provider will either:
 
        (1) provide cash collateral security sufficient to enable Standard &
    Poor's, Moody's and Fitch to confirm that the downgrade will not cause a
    reduction in or a withdrawal of the rating of the Notes; or
 
                                      133
<PAGE>
        (2) arrange for a suitably rated counterparty to intermediate the swap
    or act as substitute swap provider.
 
TERMINATION
 
    The following events are events of default under the Interest Rate Swap
Agreements: (i) failure by Westpac or the Issuer Trustee to make, when due, any
payment or delivery required by the agreement and such failure is not remedied
by the tenth local business day; and (ii) an Insolvency Event has occurred in
respect of Westpac or the Issuer Trustee; provided, however, that an Insolvency
Event in relation to the Issuer Trustee in its personal capacity is not an event
of default if the relevant Swap is novated within 30 Business Days of that
Insolvency Event and the novation will not cause a reduction or withdrawal of
the rating of the Offered Notes. Upon novation of the Swap, the successor Issuer
Trustee will assume the rights and obligations of the Issuer Trustee under the
Interest Rate Swap.
 
    An event which constitutes illegality will be a termination event under the
Interest Rate Swap Agreements. If there is a downgrading of the Interest Rate
Swap Provider's short term debt rating below A-l+, A2 or F-1+ by either Standard
& Poor's, Moody's or Fitch, respectively, and the Interest Rate Swap Provider
fails to act, as described in "--Downgrade of Interest Swap Provider" above, it
will be an "Additional Termination Event" under the Variable Rate Basis Swap. If
under similar circumstances the Interest Rate Swap Provider fails to establish
certain collateral arrangements it will be an "Additional Termination Event"
under each of the Fixed Rate Basis Swaps only at the discretion of the Issuer
Trustee. The "Automatic Early Termination" provisions under the Fixed and
Variable Rate Basis Swaps do not apply.
 
    Upon the termination of an Interest Rate Basis Swap, a termination payment
calculated pursuant to the Loss Method (as defined in such Interest Rate Basis
Swap) will be due to be paid by the Issuer Trustee to the Interest Rate Swap
Provider or by the Interest Rate Swap Provider to the Issuer Trustee. The
termination payment with respect to the Variable Rate Basis Swap will be zero.
The Issuer Trustee may look to any cash collateral security posted by the
Interest Rate Swap Provider relating to the terminated Interest Rate Basis Swap
for satisfaction of the Interest Rate Swap Provider's termination payment.
 
NOVATION
 
    Upon the novation of a Interest Rate Swap Agreement, either the Interest
Rate Swap Provider will pay to the substitute Interest Rate Swap Provider an
up-front premium or the substitute Interest Rate Swap Provider will pay to the
Interest Rate Swap Provider an up-front premium to preserve the economic
equivalent of the mark-to-market value of the swap transaction as of the date of
novation. The Issuer Trustee will not bear any risk with respect to the novation
of an Interest Rate Swap unless the Interest Rate Swap Provider is unable to pay
any required up-front premium and there is insufficient cash collateral security
posted with respect to such Interest Rate Swap to cover such premium.
 
THRESHOLD RATE
 
    If at any time the Variable Rate Basis Swap is terminated, the Trust Manager
must, on each Collection Determination Date following that termination,
calculate the minimum rate of interest that must be set on the Housing Loans
which are subject to a discretionary variable rate, in order to cover (assuming
all counterparties to the Transaction Documents, the Housing Loans and any
Mortgages and other relevant documents meet their obligations), when aggregated
with the income produced by all other Housing Loans and taking into account the
other Swap Agreements, the obligations of the Trust (the "Threshold Rate"). If
the Servicer is notified of the Threshold Rate, it is required, subject to the
terms of the relevant Housing Loans, to ensure that the rate of interest on each
relevant discretionary variable rate Housing Loan is not less than the Threshold
Rate (see "DESCRIPTION OF THE SERVICING AGREEMENT" above).
 
                                      134
<PAGE>
DESCRIPTION OF CURRENCY SWAPS
 
    The following sections contain a summary of the material terms of the
Currency Swaps, which the Issuer Trustee will enter into with Morgan Guaranty
Trust Company of New York, acting through its London Branch ("Morgan Guaranty")
and Westpac (together, the "Currency Swap Providers" and together with the
Interest Rate Swap Provider, the "Swap Providers"). The summary does not purport
to be complete and is subject to the provisions of the Currency Swaps. The
Currency Swaps are provided on a "joint and several" basis by Westpac and Morgan
Guaranty Trust Company of New York, acting through its London Branch. See
"--Cross Support."
 
   
    Collections in relation to the Housing Loans and related Mortgages and under
the Variable Rate Basis Swap and the Fixed Rate Basis Swaps will be denominated
in Australian dollars. However, the payment obligations of the Issuer Trustee in
relation to Interest and principal on the Offered Notes are denominated in
United States dollars. To hedge its currency exposure, the Issuer Trustee will
enter into four distinct swap transactions, relating to the Class A Notes and
the Class B Notes, respectively (together, the "Currency Swaps") with the
Currency Swap Providers. The Currency Swaps will be governed by an ISDA Master
Agreement dated on or about            , 1998, by and between the Issuer Trustee
and Morgan Guaranty (governed by English law) and an ISDA Master Agreement dated
on or about            , 1998, by and between the Issuer Trustee and Westpac
(governed by Australian law) respectively. Each ISDA Master Agreement will be
amended by a schedule thereto. Each swap transaction will be confirmed by a
written confirmation (such ISDA Master Agreements, the schedules thereto and the
related swap confirmations, the "Currency Swaps").
    
 
    Under the Currency Swaps, the Issuer Trustee is required to pay to the
Currency Swap Providers on each Payment Date amounts in A$ equal to a certain
percentage of the amount of any Principal Collections to be paid to the Class A
and Class B Noteholders received by the Issuer Trustee (the percentage being
that which is described in the section entitled "DESCRIPTION OF THE OFFERED
NOTES--Payments of Principal on the Notes") and the Currency Swap Providers are
required to pay to or at the direction of the Issuer Trustee an amount
denominated in US$ which is equivalent to such A$ payment (calculated by
reference to an exchange rate which is fixed at the Closing Date and set forth
in the related swap confirmations). In addition, under the Currency Swaps on
each Payment Date the Issuer Trustee will make A$ floating rate payments to the
Currency Swap Providers and the Currency Swap Providers will make US$ floating
rate payments which are equivalent in amount to the Interest payable in US$ to
the Offered Noteholders. If on any Payment Date, the Issuer Trustee does not or
is unable to make the full floating payment, the US$ floating rate payment to be
made by the Currency Swap Providers on such Payment Date will be reduced by the
same proportion as the reduction in the payment from the Issuer Trustee.
 
    Subscription amounts for the Offered Notes will be paid by investors in US$,
but the consideration for the purchase by the Issuer Trustee of equitable title
to the Housing Loans and related Mortgages will be in A$. Under the Currency
Swaps, an amount equal to the US$ subscription amounts will be paid to the
Currency Swap Providers, which will pay the A$ Equivalent of such amounts to the
Issuer Trustee.
 
    On the Closing Date the Issuer Trustee will be obliged to pay to the
Currency Swap Providers an amount equal to the proceeds of the issue of the
Offered Notes in US$. In return the Issuer Trustee will be paid the A$
equivalent of that US$ amount (calculated by reference to an exchange rate which
is fixed by the Closing Date (in the swap confirmations)).
 
    The Series Notice requires that the Issuer Trustee direct the Currency Swap
Providers to pay all US$ amounts to the Principal Paying Agent or the US$
Account. All US$ amounts shall be paid to the Offered Noteholders in accordance
with their entitlements and the priorities set out in "DESCRIPTION OF THE
OFFERED NOTES."

<PAGE>
TERMINATION OF THE CURRENCY SWAPS BY THE CURRENCY SWAP PROVIDERS
 
    Under the Currency Swaps each Currency Swap Provider shall have the right to
terminate its currency swap in the following circumstances:
 
        (1) If the Issuer Trustee fails to make a payment under the Currency
    Swap within the 10 Business Days.
 
        (2) If due to change in law it becomes illegal for the Issuer Trustee or
    a Currency Swap Provider to make or receive payments or comply with any
    other material provision of the Currency Swaps, the Currency Swap requires
    such party to make certain efforts to transfer its rights and obligations to
    another office or another affiliate to avoid this illegality (so long as the
    transfer would not result in a downgrade of the rating of the Notes). If
    those efforts are not successful then the applicable Currency
    Swap Provider will have the right to terminate. These provisions relating to
    termination following an illegality have been modified so that they are not
    triggered by the introduction of certain exchange controls by any Australian
    Government body.
 
        (3) The Currency Swap Providers have the limited right to terminate
    where it is required to gross-up or receive payments from which amounts have
    been withheld if the Note Trustee is satisfied that the Noteholders will be
    paid in full.
 
        (4) An Insolvency Event with respect to the Issuer Trustee occurs.
 
        (5) Any Event of Default occurs and an Extraordinary Resolution of the
    Voting Mortgagees is passed directing the Security Trustee to take certain
    actions.
 
TERMINATION OF THE CURRENCY SWAPS BY THE ISSUER TRUSTEE
 
    There are a number of circumstances in which the Issuer Trustee has the
right to terminate the Currency Swaps with respect to a Swap Provider. In each
of these cases it is only permitted to exercise that right with the prior
written consent of the Note Trustee:
 
        (1) Where the Currency Swap Providers fail to make a payment under the
    Currency Swap within 10 Business Days or the Currency Swap Providers become
    insolvent or merge into another entity without that entity properly assuming
    responsibility for the obligations of the Currency Swap Providers under the
    Currency Swaps.
 
        (2) If it becomes illegal for either party to make or receive payments
    under the Currency Swap or perform any of its other material obligations
    under it, both the Issuer Trustee and the Currency Swap Providers are
    obliged to make certain efforts to transfer their rights and obligations to
    avoid that illegality. If those efforts fail the Currency Swaps may be
    terminated.
 
        (3) If the Issuer Trustee becomes obliged under the Currency Swaps to
    receive payments from which amounts have been withheld or deducted
    (including where this situation arises from a merger affecting the Currency
    Swap Providers).
 
        (4) If the Issuer Trustee becomes obliged to make a withholding or
    deduction in respect of the Offered Notes and, as a result, the Offered
    Notes are redeemed.
 
    The Issuer Trustee (and the Note Trustee) may only terminate the Currency
Swaps following prior consultation by the Note Trustee with the Currency Swap
Providers as to the timing of termination. The Issuer Trustee will exercise such
right to terminate at the direction of the Trust Manager. The Currency Swap
Providers acknowledge that the Trust Manager will perform the day to day
management of the Trust and may exercise or satisfy any of the Issuer Trustee's
rights or obligations under the Currency Swap.
 
                                      136
<PAGE>
TERMINATION PAYMENTS
 
    On the Termination Date or the Early Termination Date (each as defined in
the Currency Swaps) in respect of the Currency Swaps, a termination payment will
be due to be paid by the Issuer Trustee to the Currency Swap Providers or to the
Issuer Trustee by the Currency Swap Providers in respect of the Currency Swaps.
The termination of a Currency Swap is an Event of Default under the Security
Trust Deed. If the Security Trust Deed is enforced after such Events of Default,
there is no guarantee that upon any such termination the funds realized from the
sale of the relevant Loans and Mortgages plus or minus (as the case may be) the
termination payment due in respect of the Currency Swaps will be sufficient to
pay in full amounts owing to the holders of the relevant Notes.
 
    The termination payment in respect of a Currency Swap will be determined on
the basis of quotations from four leading dealers in the relevant market
(selected by the Currency Swap Providers) to enter into a replacement
transaction that would have the effect of preserving the economic equivalent of
any payment that would, but for the early termination, have been required under
the terms of the Currency Swap.
 
REPLACEMENT OF CURRENCY SWAPS
 
    If the Currency Swaps are terminated with respect to a Currency Swap
Provider, the Issuer Trustee may (at the direction of the Trust Manager) enter
into one or more currency swaps which replaces the terminated Currency Swap
(other than by way of transfer to avoid termination of the swap) (a "Replacement
Currency Swap") but only on the condition that the Settlement Amount (as defined
in the ISDA Master Agreement) payable (if any) by the Issuer Trustee to the
Currency Swap Provider upon termination of the original Currency Swap will be
paid in full when due in accordance with the Series Notice and the Currency
Swap. If the condition in the previous sentence is satisfied, the Issuer Trustee
may enter into the Replacement Currency Swap and if it does so it must direct
the premium payable by the provider of the Replacement Currency Swap to be paid
directly to the applicable Currency Swap Provider in satisfaction of and to the
extent of the Issuer Trustee's obligation to pay the termination payment to such
Currency Swap Provider. If such premium paid by the Replacement Swap Provider is
less than the Settlement Amount due to the Currency Swap Provider, the balance
may be satisfied by the Issuer Trustee as a Trust Expense.
 
DOWNGRADE OF CURRENCY SWAP PROVIDERS
 
    Each Currency Swap Provider, severally, will give a commitment to provide
collateral in respect of the Currency Swap to which it is a party in the event
that the rating that is given to senior debt which is jointly supported by the
two Currency Swap Providers is ever downgraded below a specified level, such
that Moody's would downgrade the rating on the Class A Notes.
 
CROSS SUPPORT
 
    Each Currency Swap Provider has agreed to pay on demand of the Issuer
Trustee to or at the direction of the Issuer Trustee any amounts that the other
Currency Swap Provider is required to pay pursuant to the relevant Currency Swap
but has failed to pay. So long as a Currency Swap Provider pays such amounts,
the Issuer Trustee shall not be entitled to terminate the relevant Currency Swap
with respect to such default. In any case, a Currency Swap Provider may, in
certain circumstances, elect to replace the defaulting other Currency Swap
Provider with itself or another suitably rated party approved by the Issuer
Trustee, the Trust Manager and the Note Trustee.

                   CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS
 
    The following discussion contains summaries of legal aspects of Australian
retail housing loans and mortgages that are general in nature. The summaries do
not purport to be complete. In addition, certain of those legal aspects are
governed by the law of the applicable State or Territory (which laws may differ
substantially between States and Territories) and the summaries do not reflect
the particular laws of any particular state or encompass all relevant laws of
all states in which any Mortgaged Property may be situated. The summaries are
subject to the applicable Australian federal and state laws governing real
property and the granting and enforcement of security over real property.
 
GENERAL
 
    Generally each Housing Loan will be secured by a mortgage which has a first
ranking priority over all other mortgages granted by the relevant Borrower and
over all unsecured creditors of the Borrower (except in respect of certain
statutory rights such as some rates and taxes, which are granted statutory
priority or if the Housing Loan is not secured by a first ranking mortgage the
Approved Seller will assign to the Issuer Trustee all prior ranking registered
mortgages in relation to that Housing Loan). The Borrower is prohibited under
its loan documents from creating another mortgage or other security interest
over the relevant Mortgaged Property without the consent of Westpac. There are
two parties to a mortgage, the
 
                                      138
<PAGE>
mortgagor, who is the borrower and homeowner (or, where the relevant loan is
guaranteed and the guarantee is secured by a mortgage, the guarantor) and who
grants the mortgage over their property, and the mortgagee who is the lender.
 
NATURE OF HOUSING LOANS AS SECURITY
 
    There are a number of different forms of title to land in Australia. The
most common forms of title in Australia, and the only form of title which may
constitute Mortgaged Property is "Torrens title."
 
TORRENS TITLE
 
    "Torrens title" land is freehold or leasehold title, interests in which are
created by registration in one or more central land registries of the relevant
State or Territory. Each parcel of land is represented by a specific certificate
of title. The original certificate is retained by the registry, and in most
States a duplicate certificate is issued to the owner. Any dealing with the
relevant land is carried out by pro forma instruments which become effective on
registration.
 
    Ordinarily the relevant certificate of title (or any registered plan
referred to in it) will reveal the position and dimensions of the land, the
present owner, and any leases, mortgages and registered easements to which it is
subject. The certificate is conclusive evidence (except in limited
circumstances, such as fraud) of the matters stated in it.
 
STRATA TITLE
 
    "Strata title" was developed to facilitate the creation of, and dealings
with, apartment units (which are similar to condominiums in the United States)
and is governed by the legislation of the State or Territory in which the
property is situated. Under strata title, each proprietor has title to, and may
freely dispose of, their unit. All proprietors are members of a "body
corporate", which is vested with the control, management and administration of
the common property and the strata scheme generally, for the benefit of the
proprietors, including the rules governing the apartment block. Certain parts of
the property, such as the land on which the building is erected, the stairwells,
entrance lobbies and the like are known as "common property" and are held by the
body corporate for the benefit of the individual proprietors.
 
    Only Torrens title land can be the subject of strata title in this way, and
so the provisions referred to in this section in relation to Torrens title apply
to the title in a unit held by a strata proprietor.
 
URBAN LEASEHOLD
 
   
    All land in the Australian Capital Territory is owned by the Commonwealth of
Australia and is subject to a leasehold system of land tenure. Mortgaged
Property in that jurisdiction comprises a Crown lease and developments on the
land are subject to that lease. Any such lease:
    
 
    (a) cannot have a term exceeding 99 years, although the term can be extended
       under a straightforward administrative process in which the only
       qualification to be considered is whether the land may be required for a
       public purpose; and
 
    (b) where they involve residential property are subject to a nominal rent of
       5 cents per annum on demand.
 
    As with other Torrens title land, the Borrower's leasehold interest in the
land is entered in a central register and the Borrower may deal with their
leasehold interest (including granting a mortgage over the property) without
consent from the government.
 
    In all cases where Mortgaged Property consists of a leasehold interest, the
unexpired term of the lease exceeds the term of the Housing Loan secured by that
Mortgaged Property.
 
                                      139
<PAGE>
    Leasehold property may become subject to native title claims. Native title
has only quite recently been recognised by Australian courts. Native title to
particular property is based on the traditional laws and customs of indigenous
Australians and is not necessarily extinguished by grants of Crown leases over
that property. The extent to which native title exists over property (including
property subject to a Crown lease) depends on how that property was previously
used by the indigenous claimants asserting native title, and whether the native
title has been extinguished by the granting of the leasehold interest. If the
lease confers the right of exclusive possession over the property (which is
typically the case with residential leases), the current view is that native
title over the relevant property should be extinguished. Whether a lease confers
exclusive possession will depend on a construction of the lease and the
legislation under which the lease was granted.
 
   
    Housing Loans secured by Mortgaged Property which is leasehold in the
Australian Capital Territory represents only approximately 1.5% (by value) of
all Housing Loans.
    
 
TAKING SECURITY OVER LAND
 
    The law relating to the granting of securities over real property is made
complex by the fact that each State and Territory has separate governing
legislation. The following is a brief overview of general issues involved in
taking security over land.
 
    Under Torrens title, registration of a mortgage using the prescribed form
executed by the mortgagor is required in order for the mortgagee to obtain the
remedies of a mortgagee granted by statute and the relevant priorities against
other secured creditors. To this extent the mortgagee is said to have a legal
(i.e., registered) title. However, registration does not transfer title in the
property--the mortgagor remains as legal owner. Rather, the Torrens mortgage
operates as a statutory charge. The mortgagee does not obtain an estate in the
property but does have an interest in the land which is marked on the register
and the "certificate of title" for the property. A search of the register by any
subsequent lender will reveal the existence of the prior mortgage.
 
    In most States and Territories, a mortgagee will retain a duplicate
certificate of title (which mirrors the original certificate of title held at
the relevant land registry office). Although the certificate is not a document
of title as such, the procedure for replacement is sufficiently onerous to act
as a deterrent against most mortgagor fraud. Failure to retain the certificate
may in certain circumstances constitute negligent conduct resulting in a
postponement of the mortgagee's priority to a later secured creditor.
 
    In Queensland, under the Land Title Act 1994, duplicate certificates of
title are no longer issued to mortgagees as a matter of practice. A record of
the title is stored on computer at the land registry office and the mortgage is
registered on that computerized title.
 
    Once the mortgagor has repaid the debt, a discharge executed by the
mortgagee is lodged with the registrar by the mortgagor or the mortgagee and the
mortgage is noted as having been released.
 
WESTPAC AS MORTGAGEE
 
    Westpac is, and until a Title Perfection Event occurs intends to remain, the
registered mortgagee of all the Mortgages. The relevant Borrowers will not be
aware of the equitable assignment of the Housing Loans and Mortgages to the
Issuer Trustee.
 
    Prior to any Title Perfection Event Westpac, or the Servicer on its behalf,
will undertake any necessary enforcement action with respect to defaulted
Housing Loans and Mortgages. Following a Title Perfection Event, the Issuer
Trustee is entitled (under an irrevocable power of attorney granted to it by
Westpac) to be registered as mortgagee of the Mortgages. Until that registration
is achieved, the Issuer Trustee or the Trust Manager is entitled to lodge
caveats on the register to notify its interest publicly.
 
                                      140
<PAGE>
ENFORCEMENT OF HOUSING LOANS
 
    Subject to the discussion below, if a Borrower defaults under a Housing
Loan, the loan documents provide that all moneys under the loan may be declared
immediately due and payable. In Australia, a lender may sue to recover all
outstanding principal, interest and fees under the personal covenant of a
borrower contained in the loan documents to repay those amounts. In addition,
the lender may enforce a registered mortgage in relation to the defaulted loan.
Enforcement may occur in a number of ways, including the following:
 
        (a) The mortgagee may enter into possession of the property. If it does
    so, it does so in its own right and not as agent of the mortgagor, and so
    may be personally liable for mismanagement of the property and to third
    parties as occupier of the property;
 
        (b) The mortgagee may, in limited circumstances, lease the property to
    third parties;
 
        (c) The mortgagee may foreclose on the property--that is, extinguish the
    mortgagor's title to the property so that the mortgagee becomes the absolute
    owner of the property (a remedy that is, because of procedural constraints,
    rarely used). If the mortgagee forecloses on the property, it loses the
    right to sue the borrower under the personal covenant to repay and can look
    only to the value of the property for satisfaction of the debt;
 
        (d) The mortgagee may appoint a receiver to deal with income from the
    property or exercise certain other rights delegated to the receiver by the
    mortgagee. Unlike a mortgagee in possession, a receiver is the agent of the
    mortgagor and so in theory the mortgagee is not liable for the receiver's
    acts or as occupier of the property. In practice, the receiver will require
    indemnities from the mortgagee that appoints it; or
 
        (e) The mortgagee may sell the property, subject to various duties to
    ensure that the mortgagee exercises proper care in relation to the sale.
    This power of sale is usually expressly contained in the mortgage documents,
    and is also implied into registered mortgages under the relevant Torrens
    title legislation. The Torrens title legislation prescribes forms and
    periods of notice to be given to the mortgagor prior to enforcement.
 
    A sale under a mortgage may be by public auction or private treaty. Once
registered, the purchaser of property sold pursuant to a mortgagee's power of
sale becomes absolute owner of the property.
 
    A mortgagee's ability to call all amounts under a housing loan or enforce a
mortgage which is subject to the Consumer Credit Legislation is limited by
various demand and notice procedures which are required to be followed. For
example, as a general rule enforcement cannot occur unless the relevant default
is not remedied within 30 days after a default notice is given. Borrowers may
also be entitled to initiate negotiations with the mortgagee for a postponement
of enforcement proceedings.
 
PENALTIES AND PROHIBITED FEES
 
    Australian courts will not enforce an obligation of a borrower to pay
default interest on delinquent required payments if the court determines that
the relevant default interest rate is a penalty. Certain jurisdictions prescribe
a maximum recoverable interest rate, although in most jurisdictions there is no
specified threshold rate to determine what is a penalty. In those circumstances,
whether a rate is a penalty or not will be determined by reference to such
factors as the prevailing market interest rates. The Consumer Credit Legislation
does not impose a limit on the rate of default interest, but a rate which is too
high may entitle the borrower to have the loan agreement re-opened on the ground
that it is unjust. Under the Corporations Law, the liquidator of a company may
avoid a loan under which an extortionate interest rate is levied.
 
    The Consumer Credit Legislation requires that any fee or charge to be levied
by the lender must be provided for in the contract, otherwise it cannot be
levied. The regulations under the Consumer Credit
 
                                      141
<PAGE>
Legislation may also from time to time prohibit certain fees and charges. The
Consumer Credit legislation also requires that establishment fees, termination
fees and prepayment fees must be reasonable otherwise they may be reduced or set
aside.
 
CONSUMER CREDIT LEGISLATION
 
    Some of the Housing Loans are regulated by consumer credit legislation (the
"Consumer Credit Legislation"). Under that legislation, a Borrower has the right
to apply to a court to:
 
        (1) vary the terms of his or her Housing Loan on the grounds of hardship
    or that it is an unjust contract;
 
        (2) reduce or cancel any interest rate payable on the Housing Loan which
    is unconscionable;
 
        (3)have certain provisions of the Housing Loan or relevant Mortgage
    which are in breach of the legislation declared unenforceable; or
 
        (4) obtain restitution or compensation from either Westpac or, following
    a Title Perfection Event, the Issuer Trustee, in relation to any breaches of
    the Consumer Credit Legislation in relation to the Housing Loan or relevant
    Mortgage.
 
    Any such order may affect the timing or amount of interest or principal
payments or repayments under the relevant Housing Loan (which might in turn
affect the timing or amount of Interest or principal payments or repayments
under the Offered Notes).
 
    In addition, a mortgagee's ability to enforce a mortgage which is subject to
the Consumer Credit Legislation is limited by various demand and notice
procedures which are required to be followed. For example, as a general rule
enforcement cannot occur unless the relevant default is not remedied within 30
days after a default notice is given. Borrowers may also be entitled to initiate
negotiations with the mortgagee for a postponement of enforcement proceedings.
Such procedures and negotiations may also affect the timing or amount of
interest or principal payments or repayments under the Housing Loans.
 
    Breaches of the Consumer Credit Legislation may also lead to civil penalties
or criminal fines being imposed on Westpac, for so long as it holds legal title
to the Housing Loans and the Mortgages. If the Issuer Trustee acquires legal
title, it will then become primarily responsible for compliance with the
Consumer Credit Legislation. The Issuer Trustee will (subject to limited
exceptions) be indemnified out of the assets of the Trust for its liabilities
under the Consumer Credit Legislation. If the Issuer Trustee is indemnified with
respect to such liabilities out of the assets of the Trust, proceeds of the
Trust may be insufficient to make all payments provided for under the Offered
Notes.
 
    Westpac will give, or has given, certain representations and warranties that
the Housing Loans and related Mortgages comply in all material respects with the
Consumer Credit Legislation in force at the time documents were entered into.
The Servicer has undertaken to comply with the Consumer Credit Legislation in
connection with servicing the Housing Loans and related Mortgages where failure
to do so would have an Adverse Effect. An "Adverse Effect" is an event which
will materially and adversely affect the amount of any payment to be made to any
Noteholder, or will materially and adversely affect the timing of such payment.
In certain circumstances the Issuer Trustee may have the right to claim damages
from Westpac or the Servicer, as the case may be, where the Issuer Trustee
suffers a loss in connection with a breach of the Consumer Credit Legislation
which is caused by a breach of a relevant representation or undertaking.
 
BANKRUPTCY
 
    The insolvency of a natural person is governed by the provisions of the
Bankruptcy Act 1966, which is a federal statute. Generally, secured creditors of
a natural person (such as mortgagees under real property mortgages) stand
outside the bankruptcy--that is, the property of the bankrupt which is available
for distribution by the trustee in bankruptcy does not include the secured
property. The secured creditor may, if it wishes, prove in the bankruptcy
proceeding as an unsecured creditor in a number of circumstances,
 
                                      142
<PAGE>
including if they have realized the related mortgaged property and their debt
has not been fully repaid (in which case they can prove for the unpaid balance).
 
    Certain dispositions of property by a bankrupt may be avoided by the trustee
in bankruptcy. These include where (a) the disposition was made to defraud
creditors; or (b) the disposition was made by an insolvent debtor within 6
months of the petition for bankruptcy and gave a preference to an existing
creditor over at least one other creditor.
 
    The insolvency of a company is governed by the Corporations Law of the
relevant Australian jurisdiction. Again, secured creditors generally stand
outside the insolvency. However, a liquidator may avoid a mortgage which is
voidable under the Corporations Law because it is an uncommercial transaction,
or an unfair preference to a creditor or a transaction for the purpose of
defeating creditors, and that transaction occurred when the company was
insolvent (or an act is done to give effect to the transaction when the company
is insolvent, or the company becomes insolvent because of the transaction or the
doing of an act to give effect to the transaction), and the transaction occurred
within a prescribed period prior to the commencement of the winding up of the
company. The liquidator may also avoid a loan under which an extortionate
interest rate is levied.
 
ENVIRONMENTAL
 
    Real property which is mortgaged to a lender may be subject to unforeseen
environmental problems, including land contamination. Environmental legislation
which deals with liability for such problems exists at both state and federal
levels, although the majority of relevant legislation is imposed by the states.
No Australian statute expressly imposes liability on "passive" lenders or
security holders for environmental matters, and some states expressly exclude
such liability. However, liability in respect of environmentally damaged land
(which liability may include the cost of rectifying the damage) may attach to a
person who is, for instance, an owner, occupier or person in control of the
relevant property. In some but not all states, lenders are expressly excluded
from the definitions of one or more of these categories.
 
    Merely holding security over property will not convert a lender into an
occupier. However, a lender or receiver who goes into possession of contaminated
mortgaged property or otherwise enforces its security may be liable as an
occupier.
 
    Some environmental legislation provides that security interests may be
created over contaminated or other affected property to secure payment of the
costs of any necessary rectification of the property. The security interests may
have priority over pre-existing mortgages.
 
INSOLVENCY CONSIDERATIONS
 
    The current transaction is designed to minimize insolvency risk. For
example, the equitable assignment of the Housing Loans by Westpac to the Issuer
Trustee should ensure that the Housing Loans are not assets available to the
liquidator or creditors of Westpac in the event of an insolvency of Westpac.
Similarly, the assets in the Trust should not be available to other creditors of
the Issuer Trustee in its personal capacity or as trustee of any other trust in
the event of an insolvency of the Issuer Trustee.
 
    If any Insolvency Event occurs with respect to the Issuer Trustee, the
Security Trust Deed may be enforced by the Security Trustee at the direction of
the Voting Mortgagees (see "SECURITY FOR THE NOTES--Enforcement"). The security
created by the Security Trust Deed will stand outside any liquidation of the
Issuer Trustee, and the assets the subject of that security will not be
available to the liquidator or any creditor of the Issuer Trustee (other than a
creditor which has the benefit of the Security Trust Deed) in priority to the
Security Trust Deed. The proceeds of enforcement of the Security Trust Deed are
to be applied by the Security Trustee as set out in "SECURITY FOR THE
NOTES--Priorities under the Security Trust Deed". If the proceeds from
enforcement of the Security Trust Deed are not sufficient to redeem the Notes in
full, some or all of the Noteholders will incur a loss.
 
TREATMENT OF INTEREST PAYMENTS WITH RESPECT TO AUSTRALIAN HOUSING LOANS
 
    Under Australian law, interest on loans used to purchase a person's primary
place of residence is not ordinarily deductible for taxation purposes.
Conversely, interest payments on mortgage loans and other non-capital
expenditures relating to investment properties that generate taxable income are
generally allowable as tax deductions.

<PAGE>
                                USE OF PROCEEDS
 
   
    The net proceeds from the sale of the Offered Notes will amount to
A$2,252,766,010 and will be used by the Issuer Trustee to acquire equitable
title to the Housing Loans and related Mortgages from the Approved Sellers and
for general expenses (including any premium payable to any Swap Provider) in
relation to the Trust.
    
 
                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a general discussion of the anticipated material United
States federal income tax consequences of the purchase, ownership and
disposition of Offered Notes by Noteholders who are subject to United States
federal income tax. The summary is based on laws, regulations, rulings and
decisions now in effect, all of which are subject to change (possibly with
retroactive effect) or to different interpretation. The summary does not purport
to address federal income tax consequences applicable to particular categories
of investors, some of which (for example, insurance companies, dealers in
securities, financial institutions or foreign investors) may be subject to
special rules. In addition, this summary is generally limited to investors who
will hold the Notes as "capital assets" (generally, property held for
investment) within the meaning of Section 1221 of the Internal Revenue Code of
1986, as amended (the "Code"). Investors are urged to consult their own tax
advisors with regard to the application of the tax considerations discussed
below to their particular situations, as well as the consequences to them under,
state, local, non-United States and any other tax law of the purchase, ownership
and disposition of the Offered Notes, including the advisability of making any
election discussed below. Prospective investors should note that no rulings have
been or will be sought from the Internal Revenue Service (the "IRS" or the
"Service") with respect to any of the federal income tax consequences discussed
below, and no assurance can be given that the IRS will not take contrary
positions. It is anticipated that the Issuer Trustee will not be indemnified for
any United States federal income taxes that may be imposed upon it, and the
imposition of any such taxes on the Trust could result in a reduction in the
amounts available for distribution to the Noteholders.
 
    In the opinion of Mayer, Brown & Platt, tax counsel to the Issuer Trustee
("Tax Counsel"), for United States federal income tax purposes, the Offered
Notes will be characterized as debt of the Issuer Trustee. Each Noteholder, by
the acceptance of an Offered Note, will agree to treat the Offered Notes as
indebtedness for federal income tax purposes.
 
GENERAL
 
    Each Noteholder will be required to report on its federal income tax return
interest income on the Offered Notes held by it in accordance with such
Noteholder's method of accounting.
 
SALES OF NOTES
 
    A Noteholder's tax basis in an Offered Note will equal its cost of such
Offered Note, reduced by any amortized premium (as described below) and any
payments other than interest made on such Offered Note and increased by any
market discount or original issue discount included in the Noteholder's income.
A Noteholder that sells an Offered Note will recognize gain or loss (in the
aggregate) in an amount equal to the difference between its adjusted tax basis
in the Offered Note and the amount realized on the sale (except to the extent
attributable to accrued interest, which should be taxable as interest income).
Subject to the market discount provisions of the Code (described below), any
such gain or loss will be capital gain or loss if the Offered Note was held as a
capital asset and, if the Offered Note was held for more than one year, will be
long-term capital gain or loss. In the case of an individual taxpayer, any
capital gain on the sale of an Offered Note will be taxed at a maximum rate of
39.6% if the Offered Note is held for not more than 12 months, at 28% if the
Offered Note is held for more than 12 months, but not more than 18 months, and
at 20% if the Offered Note is held for more than 18 months. Any capital losses
realized will be deductible by a corporate taxpayer only to the extent of
capital gains and by an individual taxpayer only to the extent of capital gains
plus U.S. $3,000 of other income.
 
                                      144
<PAGE>
MARKET DISCOUNT
 
    A purchaser of an Offered Note will be considered to have acquired such
Offered Note at a "market discount" to the extent the remaining principal amount
of such Offered Note exceeds the Noteholder's tax basis in such Offered Note,
unless the excess does not exceed a prescribed DE MINIMIS amount. In the event
such excess exceeds the DE MINIMIS amount, the Noteholder will be subject to the
market discount rules of Sections 1276 and 1278 of the Code with regard to such
Offered Note.
 
    In the case of a sale or other disposition of an Offered Note subject to the
market discount rules, Section 1276 of the Code requires that gain, if any, from
such sale or disposition be treated as ordinary income to the extent such gain
represents market discount that has accrued during the period in which the Note
was held by such Noteholder. In addition, a disposition of an Offered Note by
gift (and in certain other circumstances), could result in the recognition of
market discount income, computed as if such Offered Note had been sold for its
fair market value.
 
    In the case of a partial principal payment on an Offered Note subject to the
market discount rules, Section 1276 of the Code requires that such payment be
included in gross income as ordinary income to the extent such payment does not
exceed the market discount that has accrued during the period such Offered Note
was held by such Noteholder. The amount of any accrued market discount later
required to be included in income upon a disposition, or subsequent partial
principal payment, will be reduced by the amount of accrued market discount
previously included in income.
 
    Generally, market discount accrues under a straight line method, or, at the
election of the taxpayer, under a constant interest rate method. However, in the
case of bonds the principal of which may be paid in two or more installments
(such as the Offered Notes), the manner in which market discount is to be
accrued will be described in Treasury regulations that have yet to be issued.
Until such Treasury regulations are issued, the explanatory conference committee
Report to the Tax Reform Act of 1986 (the "Conference Report") indicates that
holders of such obligations may elect to accrue market discount either on the
basis of a constant interest rate or as follows: (1) for those obligations that
have original issue discount ("OID"), market discount shall be deemed to accrue
in proportion to the accrual of OID for any accrual period, and (2) for those
obligations which do not have OID, the amount of market discount that is deemed
to accrue is the amount of market discount that bears the same ratio to the
total amount of remaining market discount that the amount of stated interest
paid in the accrual period bears to the total amount of stated interest
remaining to be paid on the obligation as of the beginning of such period.
 
    Under Section 1277 of the Code, if in any taxable year interest paid or
accrued by a Noteholder on indebtedness incurred or continued to purchase or
carry an Offered Note subject to the market discount rules exceeds the interest
(including OID) currently includible in income with respect to such Offered
Note, deductions of such interest must be deferred to extent of the market
discount allocable to the taxable year. The deferred portion of any interest
expense will generally be deductible when such market discount is included in
income upon the sale or other disposition (including repayment) of the
indebtedness.
 
    Section 1278 of the Code allows a taxpayer to make an election to include
market discount in its gross income currently. If such election is made, the
rules of Sections 1276 and 1277 of the Code (described above) will not apply to
the taxpayer.
 
    Due to the complexity of the market discount rules, prospective Noteholders
are urged to consult their tax advisors as to the applicability and operation of
the market discount rules.

    A Noteholder will generally be considered to have acquired an Offered Note
at a premium to the extent the Noteholder's tax basis in such Offered Note
exceeds the remaining principal amount of such Offered Note. In that event, a
Noteholder who holds an Offered Note as a capital asset may amortize the premium
as an offset to interest income under Section 171 of the Code, with
corresponding reductions in
 
                                      145
<PAGE>
the Noteholder's tax basis in the Offered Note if an election under Section 171
of the Code is or has been made with respect to all debt instruments held by the
taxpayer (including the Offered Notes). Generally, such amortization is on a
constant yield basis. However, in the case of bonds the principal of which may
be paid in two or more installments (such as the Offered Notes), the Conference
Report indicates a Congressional intent that amortization will be in accordance
with the same rules that will apply to the accrual of market discount on such
obligations (see the discussion of market discount above).
 
BACKUP WITHHOLDING
 
    A Noteholder may be subject, under certain circumstances, to backup
withholding at a 31% rate with respect to "reportable payments" on the Offered
Notes. This withholding generally applies only if the Noteholder (i) fails to
provide the Noteholder's social security or other taxpayer identification number
("TIN"); (ii) furnishes an incorrect TIN; (iii) is notified by the Service that
the Noteholder has failed to report properly payments of interest and dividends
and the Service has notified the Issuer Trustee that the Noteholder is subject
to backup withholding; or (iv) fails, under certain circumstances, to provide a
certified statement, signed under penalty of perjury, that the TIN provided is
the Noteholder's correct number and that the Noteholder is not subject to backup
withholding. Any amount withheld from payment to a Noteholder under the backup
withholding rules is allowable as a credit against such Noteholder's federal
income tax liability, provided that the required information is furnished to the
Service. Certain Noteholders (including, among others, corporations and foreign
individuals who comply with certain certification requirements) are not subject
to backup withholding. Noteholders should consult their tax advisors as to their
qualifications for exemption from backup withholding and the procedure for
obtaining such an exemption.
 
    ALL INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE FEDERAL,
STATE, LOCAL OR FOREIGN INCOME TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF THE NOTES.
 
                         CERTAIN AUSTRALIAN TAX MATTERS
 
    THE FOLLOWING STATEMENTS WITH RESPECT TO AUSTRALIAN TAXATION ARE ONLY
GENERAL SUMMARIES AND ARE BASED ON ADVICE RECEIVED BY THE ISSUER TRUSTEE.
PURCHASERS OF OFFERED NOTES SHOULD CONSULT THEIR OWN TAX ADVISERS CONCERNING THE
CONSEQUENCES, IN THEIR PARTICULAR CIRCUMSTANCES, UNDER AUSTRALIAN TAX LAWS, AND
THE LAWS OF ANY OTHER TAXING JURISDICTION, OF THE OWNERSHIP OF OR ANY DEALING IN
THE OFFERED NOTES. ANY SUCH DEALING WOULD NEED TO COMPLY WITH THE SELLING
RESTRICTIONS AND SECURITIES LAW GENERALLY.
 
PAYMENTS OF PRINCIPAL, PREMIUMS AND INTEREST
 
    Under existing Australian tax law, non-resident holders of the Offered Notes
or interests in any Global Note (other than persons holding such securities or
interest as part of a business carried on, at or through a permanent
establishment in Australia (an "Australian Establishment")) are not subject to
Australian income tax on payments of interest or amounts in the nature of
interest, other than interest withholding tax. Under Article 11 of the 1983
United States-Australia Tax Treaty, the maximum Australian withholding rate on
interest paid to United States residents who are entitled to the benefit of such
Treaty is 10%. Under Australian law, the withholding rates for payments to other
jurisdictions is currently 10% on interest or amounts in the nature of interest
paid on the Offered Notes. A premium on redemption would generally be treated as
an amount in the nature of interest for this purpose.
 
    Pursuant to section 128F of the Australian Income Tax Assessment Act 1936
(the "Tax Act"), an exemption from Australian interest withholding tax applies
provided all prescribed conditions are met. Such conditions include the issue of
the Offered Notes in a way that satisfies an objective public offer test. The
Issuer Trustee will seek to issue the Offered Notes in a way that will satisfy
such test and otherwise meet the requirements of section 128F, including by
listing the Offered Notes.
 
                                      146
<PAGE>
    The test will not be satisfied if the Issuer Trustee knew, or had reasonable
grounds to suspect, that the Offered Notes were being or would later be acquired
either directly or indirectly by:
 
    (1) a resident of Australia for the purpose of section 128F of the Tax Act;
       or
 
    (2) an associate of the Issuer Trustee within the meaning of section 128F of
       the Tax Act, other than in the capacity of a dealer, manager or
       underwriter in relation to the placement of an Offered Note.
 
    The exemption from Australian withholding tax will also not apply to
interest paid by the Issuer Trustee to an associate of the Issuer Trustee within
the meaning of section 128F if, at the time of the payment, the Issuer Trustee
knows, or has reasonable grounds to suspect, that the person is an associate.
 
    In a press release of the Federal Government of Australia late last year
entitled INVESTING FOR GROWTH, it was announced that "in order to encourage the
deepening and greater liquidity of the domestic corporate debt market, the
interest withholding tax exemption provided under section 128F of the Income Tax
Assessment Act 1936 will be widened by removing, for eligible debentures issued
by companies, the present requirement that such debentures be issued outside
Australia and that the interest be paid outside Australia . . . this measure
will remove a tax discrimination in favour of corporate debt issued in foreign
financial markets over corporate debt issued in Australia markets."
 
    This amendment has not yet been enacted, therefore the effect, form and
timing of the proposed amendment is currently unclear.
 
PROFIT ON SALE
 
    Under current Australian law, non-resident holders of Offered Notes will not
be subject to Australian income tax on profits derived from the sale or disposal
of Offered Notes (but see below for discussion of Australia's capital gains
provisions):
 
    (1) if the profits do not have an Australian source; or
 
    (2) where the profits do have an Australian source, if the holder is
       resident in a country with which Australia has entered into a double tax
       treaty, is entitled to the benefit of that treaty and the profits are
       business profits for the purposes of the treaty which are not
       attributable to a business carried on through an Australian
       Establishment.
 
    The source of any profit on the disposal of Offered Notes will depend on the
factual circumstances of the actual disposal. Where the Offered Notes are
acquired and disposed of pursuant to contractual arrangements entered into and
concluded outside Australia, and the seller and the purchaser are non-residents
of Australia and do not have an Australian Establishment, the profit should not
have an Australian source. There are, however, specific withholding tax rules
that can apply to treat a portion of the sale price of Offered Notes as interest
for withholding tax purposes (and which amounts are not covered by the exemption
conditions in section 128F). These rules can apply when:
 
    (1) Offered Notes are sold for an amount in excess of their issue price
prior to maturity; or
 
    (2) Offered Notes are sold to an Australian resident in connection with a
"washing arrangement" (as defined in the Tax Act).
 
    Under provisions for the taxation of capital gains, non-resident holders of
Offered Notes would be subject to Australian tax on profits derived from the
sale or disposal of Offered Notes if the Offered Notes were at any time prior to
the sale or disposal held as part of a business carried on through an Australian
Establishment.
 
                                      147
<PAGE>
OTHER TAXES
 
    No stamp, issue, registration or similar taxes are payable in Australia in
connection with the issue of the Offered Notes. Furthermore, a transfer of, or
agreement to transfer, Offered Notes executed outside of Australia will not be
subject to Australian stamp duty.
 
                              ERISA CONSIDERATIONS
 
    Subject to the considerations discussed below, the Offered Notes are
eligible for purchase by employee benefit plans.
 
    Section 406 of the Employee Retirement Income Security Act ("ERISA"), and/or
Section 4975 of the Code, prohibits a pension, profit-sharing or other employee
benefit plan, as well as individual retirement accounts and certain types of
Keogh Plans (each a "Benefit Plan") from engaging in certain transactions with
persons that are "parties in interest" under ERISA or "disqualified persons"
under the Code with respect to such Benefit Plan. A violation of these
"prohibited transaction" rules may result in an excise tax or other penalties
and liabilities under ERISA and the Code for such persons. Title I of ERISA also
requires that fiduciaries of a Benefit Plan subject to ERISA make investments
that are prudent, diversified (except if prudent not to do so) and in accordance
with governing plan documents.
 
    Certain transactions involving the purchase, holding or transfer of the
Offered Notes might be deemed to constitute prohibited transactions under ERISA
and the Code if assets of the Issuer Trustee were deemed to be assets of a
Benefit Plan. Under a regulation issued by the United States Department of Labor
(the "Plan Assets Regulation"), the assets of the Issuer Trustee would be
treated as plan assets of a Benefit Plan for the purposes of ERISA and the Code
only if the Benefit Plan acquires an "equity interest" in the Issuer Trustee and
none of the exceptions contained in the Plan Assets Regulation is applicable. An
equity interest is defined under the Plan Assets Regulation as an interest in an
entity other than an instrument which is treated as indebtedness under
applicable local law and which has no substantial equity features. Although
there can be no assurances in this regard, it appears that the Offered Notes
should be treated as debt without substantial equity features for purposes of
the Plan Assets Regulation and that the Offered Notes do not constitute equity
interests in the Issuer Trustee for purposes of the Plan Assets Regulation.
However, without regard to whether the Offered Notes are treated as an equity
interest for such purposes, the acquisition or holding of the Offered Notes by
or on behalf of a Benefit Plan could be considered to give rise to a prohibited
transaction if the Issuer Trustee, or any of its affiliates is or becomes a
party in interest or a disqualified person with respect to such Benefit Plan. In
such case, certain exemptions from the prohibited transaction rules could be
applicable depending on the type and circumstances of the plan fiduciary making
the decision to acquire an Offered Note. Included among these exemptions are:
Prohibited Transaction Class Exemption ("PTCE") 96-23, regarding transactions
effected by "in-house asset managers"; PTCE 90-1, regarding investments by
insurance company pooled separate accounts; PTCE 95-60, regarding transactions
effected by "insurance company general accounts"; PTCE 91-38, regarding
investments by bank collective investment funds; and PTCE 84-14, regarding
transactions effected by "qualified professional asset managers." By its
acquisition of an Offered Note, each purchaser shall be deemed to represent and
warrant that its purchase and holding of the Offered Note will not result in a
non-exempt prohibited transaction under ERISA or the Code.
 
    Employee benefit plans that are governmental plans (as defined in Section
3(32) of ERISA) and certain church plans (as defined in Section 3(33) of ERISA)
are not subject to ERISA requirements.
 
    A PLAN FIDUCIARY CONSIDERING THE PURCHASE OF ANY OF THE OFFERED NOTES SHOULD
CONSULT ITS TAX AND/OR LEGAL ADVISORS REGARDING WHETHER THE ASSETS OF THE ISSUER
TRUSTEE WOULD BE CONSIDERED PLAN ASSETS, THE POSSIBILITY OF EXEMPTIVE RELIEF
FROM THE PROHIBITED TRANSACTION RULES AND OTHER ISSUES AND THEIR POTENTIAL
CONSEQUENCES.

<PAGE>
                              RATINGS OF THE NOTES
 
    It is a condition to the issuance of the Class A Notes that they be rated
"AAA" by Standard & Poor's, "Aaa" by Moody's and "AAA" by Fitch. It is a
condition to the issuance of the Class B Notes that they be rated "AA-" by
Standard & Poor's and "AA-" by Fitch. The security ratings of the Offered Notes
should be evaluated independently from similar ratings on other types of
securities. A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by the
Rating Agencies. The Offered Notes are pass-through debt securities. The rating
does not address the expected schedule of principal repayments other than to say
that principal will be returned no later than the final maturity date.
 
                        LEGAL INVESTMENT CONSIDERATIONS
 
    The Offered Notes will not constitute "mortgage related securities" for
purposes of the Secondary Mortgage Market Enhancement Act of 1984 ("SMMEA"),
because the originator of the Mortgage Loans was not subject to United States
State of Federal regulatory authority. Accordingly, many institutions with legal
authority to invest in comparably rated securities based on such mortgage loans
may not be legally authorized to invest in the Offered Notes, which, for the
reasons stated herein, do not constitute "mortgage related securities" under
SMMEA. No representation is made as to whether the Offered Notes constitute
legal investments under any applicable statute, law, rule, regulation or order
for any entity whose investment activities are subject to investment laws and
regulations or to review by certain regulatory authorities. Prospective
purchasers are urged to consult with their counsel concerning the status of the
Offered Notes as legal investments for such purchasers.

    In the Underwriting Agreement, the Underwriters named therein have agreed,
subject to the terms and conditions set forth therein, to purchase all of the
Offered Notes offered hereby if any Offered Notes are purchased. In the event of
default by an Underwriter, the Underwriting Agreement provides that, in certain
circumstances, the Underwriting Agreement may be terminated.
 
   
    The Issuer Trustee has been advised by the Underwriters that they propose
initially to offer the Offered Notes to the public at the respective offering
prices set forth on the cover page hereof and to certain dealers at such prices
less concessions not to exceed    % of the Initial Invested Amount of the Class

    With respect to the Class A Notes, the Underwriters may allow and such
dealers may reallow, a concession not to exceed    % of the aggregate of the
Initial Invested Amount of the Class A Notes. With respect to the Class B Notes,
the Underwriters may allow and such dealers may reallow, a concession not to
exceed    % of the Initial Invested Amount of the Class B Notes.
    
 
    In connection with the offering, the Underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the Offered Notes.
Specifically, the Underwriters may overallot the offering, creating a syndicate
short position. In addition, the Underwriters may bid for, and purchase, the
Offered Notes in the open market to cover syndicate shorts or to stabilize the
price of the Offered Notes. Any of these activities may stabilize or maintain
the market price of the Offered Notes above independent market levels. The
Underwriters are not required to engage in these activities, and if commenced,
such activities may be discontinued at any time.
 
    After the initial public offering of the Offered Notes, the public offering
price and such concessions may be changed.
 
   
    Pursuant to the Underwriting Agreement, Westpac Securities Administration
Limited (in its capacity as trustee of the Trust only), Westpac Securitisation
Management Pty Limited and Westpac have agreed to indemnify the Underwriters
against certain liabilities, including civil liabilities under the Securities
Act, or contribute to payments which the Underwriters may be required to make in
respect thereof.

    "STRATA TITLE"  means a system of title in which the relevant land is
divided into the relevant number of units. Each proprietor has title to, and may
freely dispose of, their unit. All proprietors are members of a "body
corporate", which monitors compliance with rules governing the apartment block.
Certain parts of the property, such as stairwells, entrance lobbies and the like
are known as "common property" and are owned by the body corporate as a whole
rather than by individual proprietors.
 
    "TORRENS TITLE"  means a system of title in which the relevant land is
freehold title, interests in which are created by registration in a central land
registry of the relevant State or Territory. Each parcel of land is represented
by a specific certificate of title. The original certificate is retained by the
registry, and in most States a duplicate certificate is issued to the owner. Any
dealing with the relevant land is carried out by pro forma instruments which
become effective on registration.

distinct swap transactions relating to each of the Class A Notes and the Class B
Notes, respectively (each, a "Currency Swap", and together the "Currency

1. FORM, DENOMINATION AND TITLE
 
    The Class A Notes will be issued in registered form, without interest
coupons, in minimum denominations of US$100,000 and integral multiples thereof.
The Class A Notes will be represented by one or more typewritten fully
registered book-entry notes (each, a "Book-Entry Note" and collectively, the
"Book-Entry Notes") registered in the name of Cede & Co. ("Cede") as nominee of
The Depository Trust Company ("DTC"). Beneficial interests in the Book-Entry
Notes will be shown on, and transfers thereof will be effected only through,
records maintained by DTC and its participants. Morgan Guaranty Trust Company of
New York, Brussels office, as operator of the Euroclear System ("Euroclear") and
Cedel
Bank, societe anonyme ("Cedel Bank"), may hold interests in the Book-Entry Notes
on behalf of persons who have accounts with Euroclear and Cedel Bank through
accounts maintained in the names of Euroclear or Cedel Bank, or in the names of
their respective depositories, with DTC.
 
   
    If the Issuer Trustee is obliged to issue Definitive Notes under clause 3.3
of the Note Trust Deed, interests in the applicable Book-Entry Note will be
transferred to the beneficial owners thereof in the form of Definitive Notes,
without interest coupons, in the denominations set forth above. A Definitive
Note will be issued to each Noteholder in respect of its registered holding or
holdings of Class A Notes against delivery by such Noteholders of a written
order containing instructions and such other information as the Issuer Trustee
and Morgan Guaranty Trust Company of New York, London Branch acting as note
registrar (the "Note Registrar") may require to complete, execute and deliver
such Definitive Notes. In such circumstances, the Issuer Trustee will cause
sufficient Definitive Notes to be executed and delivered to the Note Registrar
for completion, authentication and dispatch to the relevant Noteholders.
    
 
2. STATUS, SECURITY AND RELATIONSHIP BETWEEN THE CLASS A NOTES, THE CLASS B
  NOTES, THE RFSS AND THE RFS CLASS A NOTES
 
    The Class A Notes are secured by a first ranking floating charge over all of
the assets of the Trust (which include, among other things, the Loans (as
defined below) and the Mortgages (as defined below) and related securities) (as
more particularly described in the Security Trust Deed) and rank PARI PASSU and
rateably without any preference or priority among themselves.
 
    The Class A Notes are constituted by the Master Trust Deed and the Series
Notice and are secured by the same security as secures the Class B Notes but the
Class A Notes will rank in priority to the Class B Notes in the event of the
security being enforced and in respect of principal and interest (as set out in
Class A Condition 4 and 5).
 
    The proceeds of the issue of the Class A Notes and the Class B Notes are to
be used by the Issuer Trustee to purchase an equitable interest in certain
housing loans (the "Loans") and certain related mortgages (the "Mortgages") from
Westpac or Westpac Securities Administration Limited in its capacity as trustee
of certain other trusts (each a "WST Seller").
 
                                      II-2
<PAGE>
    In the event that the security for the Class A Notes is enforced and the
proceeds of such enforcement are insufficient, after payment of all other claims
ranking in priority to or PARI PASSU with the Class A Notes under the Security
Trust Deed, to pay in full all principal and interest and other amounts
whatsoever due in respect of the Class A Notes, then the Class A Noteholders
shall have no further claim against the Issuer Trustee in respect of any such
unpaid amounts.
 
    The net proceeds of realisation of the assets of the Trust may be
insufficient to pay all amounts due to the Noteholders. Save in certain limited
circumstances the other assets of the Issuer Trustee will not be available for
payment of any shortfall arising and all claims in respect of such shortfall
shall be extinguished (see further Class A Condition 15). None of the Servicer,
the Trust Manager, the Seller Trustee, Westpac, the Note Trustee or the Security
Trustee has any obligation to any Noteholder for payment of any amount by the
Issuer Trustee in respect of the Notes.
 
    THE ISSUER TRUSTEE MAY FROM TIME TO TIME ISSUE DEBT SECURITIES ("RFSS")
CONSTITUTED UNDER THE MASTER TRUST DEED AND THE SERIES NOTICE TO FUND AMOUNTS
REDRAWN BY RELEVANT BORROWERS UNDER THE LOANS (UP TO THE SCHEDULED AMORTISED
PRINCIPAL OF THE LOANS) FROM TIME TO TIME ("REDRAWS"). RFSS WILL, ON ISSUE, RANK
PARI PASSU AND PRIOR TO ENFORCEMENT OF THE SECURITY RELATING TO THE RFSS AND THE
CLASS A NOTES RATEABLY WITHOUT ANY PREFERENCE OR PRIORITY WITH THE CLASS A NOTES
IN RELATION TO PAYMENT OF INTEREST, BUT AHEAD OF THE CLASS A NOTES IN RELATION
TO PRINCIPAL. UPON ENFORCEMENT OF THE SECURITY RELATING TO THE RFSS AND THE
CLASS A NOTES, ALL MONEYS OWING TO THE HOLDERS OF THE RFSS AND THE HOLDERS OF
THE CLASS A NOTES WILL (SUBJECT TO AMOUNTS BEING AVAILABLE FOR SUCH PAYMENT) BE
PAID PARI PASSU.
 
    IF, BY THE FIFTH COLLECTION DETERMINATION DATE (AS DEFINED IN CLASS A
CONDITION 5) FOLLOWING THE ISSUE OF AN RFS, THE RFS HAS NOT BEEN REDEEMED, IT
SHALL CONVERT TO AN RFS CLASS A NOTE (EACH, AN "RFS CLASS A NOTE" AND, TOGETHER
THE "RFS CLASS A NOTES"). RFS CLASS A NOTES RANK PARI PASSU AND RATEABLY WITHOUT
PREFERENCE OR PRIORITY WITH CLASS A NOTES IN RELATION TO BOTH INTEREST AND
PRINCIPAL. RFSS AND RFS CLASS A NOTES ARE REGISTERED, AUSTRALIAN-TRADED
INSTRUMENTS DENOMINATED IN AUSTRALIAN DOLLARS ("A$") AND SOLD TO AUSTRALIAN
INVESTORS ONLY AND FOR THE AVOIDANCE OF DOUBT ARE NOT FUNGIBLE WITH THE CLASS A
NOTES.
 
    THE NOTE TRUST DEED CONTAINS PROVISIONS REQUIRING THE NOTE TRUSTEE TO HAVE
REGARD TO THE INTERESTS OF THE CLASS A NOTEHOLDERS AND THE CLASS B NOTEHOLDERS
AS REGARDS ALL THE POWERS, TRUSTS, AUTHORITIES, DUTIES AND DISCRETIONS OF THE
NOTE TRUSTEE (EXCEPT WHERE EXPRESSLY PROVIDED OTHERWISE), BUT REQUIRING THE NOTE
TRUSTEE IN ANY SUCH CASE TO HAVE REGARD ONLY TO THE INTERESTS OF THE CLASS A
NOTEHOLDERS IF, IN THE NOTE TRUSTEE'S OPINION, THERE IS A CONFLICT BETWEEN THE
INTERESTS OF THE CLASS A NOTEHOLDERS AND THE INTERESTS OF THE CLASS B
NOTEHOLDERS.
 
    THE SECURITY TRUST DEED CONTAINS PROVISIONS REQUIRING THE SECURITY TRUSTEE
TO GIVE PRIORITY TO THE INTERESTS OF THE CLASS A NOTEHOLDERS AND THE HOLDERS OF
RFSS (IF ANY) AND RFS CLASS A NOTES (IF ANY), IF THERE IS A CONFLICT BETWEEN THE
INTERESTS OF SUCH NOTEHOLDERS AND ANY OTHER VOTING MORTGAGEE (AS DEFINED BELOW).
 
3. COVENANTS OF THE ISSUER TRUSTEE
 
    So long as any of the Class A Notes or the Class B Notes remains
outstanding, the Issuer Trustee has made certain covenants for the benefit of
Class A Noteholders and the Class B Noteholders which are set out in the Master
Trust Deed.
 
    These covenants are as follows:
 
    (a) The Issuer Trustee shall act continuously as trustee of the Trust until

Trustee has retired or been removed from office in the manner provided under the
Master Trust Deed.
 
    (b) The Issuer Trustee shall:
 
    (i) act honestly and in good faith in the performance of its duties and in
the exercise of its discretions under the Master Trust Deed;
 
                                      II-3
<PAGE>
    (ii) subject to the Master Trust Deed, exercise such diligence and prudence
as a prudent person of business would exercise in performing its express
functions and in exercising its discretions under the Master Trust Deed, having
regard to the interests of the Class A Noteholders and the Class B Noteholders
and other creditors and beneficiaries of the Trust;
 
    (iii) use its best endeavours to carry on and conduct its business in so far
as it relates to the Master Trust Deed in a proper and efficient manner;
 
    (iv) keep, or ensure that the Trust Manager keeps, accounting records which
correctly record and explain all amounts paid and received by the Issuer
Trustee;
 
    (v) keep the Trust separate from each other trust which is constituted under
the Master Trust Deed and account for assets and liabilities of the Trust
separately from those of other trusts constituted under the Master Trust Deed;
and
 
    (vi) do everything and take all such actions which are necessary (including
obtaining all appropriate authorisations) to ensure that it is able to exercise
all its powers and remedies and perform all its obligations under the Master
Trust Deed, the Transaction Documents and all other deeds, agreements and other
arrangements entered into by the Issuer Trustee under the Master Trust Deed.
 
    (c) Except as provided in the Master Trust Deed, the Issuer Trustee shall
not, nor shall it permit any of its officers to, sell, mortgage, charge or
otherwise encumber or part with possession of any asset of the Trust (the "Trust
Assets").
 
    (d) The Issuer Trustee's officers, employees, agents, attorneys, delegates
and sub-delegates shall duly observe and perform the covenants and obligations
of the Master Trust Deed in the same manner as is required of the Issuer
Trustee, and the Issuer Trustee agrees to indemnify the Trust Manager for its
own benefit or for the benefit of the Trust against any loss or damage that the
Trust, the Trust Manager, the Servicer, the Class A Noteholders, the Class B
Noteholders, the Beneficiaries (as defined in the Master Trust Deed) the holders
of RFSs (if any) and the holders of RFS Class A Notes (if any) or other
creditors incur or sustain in connection with, or arising out of, any breach or
default by such officers, employees, agents, delegates and persons in the
observance or performance of any such covenant or obligation, to the extent that
the Issuer Trustee would have been liable if that breach or default had been the
Issuer Trustee's own act or omission.
 
    (e) The Issuer Trustee will open and operate certain bank accounts in
accordance with the Master Trust Deed and the Series Notice.
 
    (f) Subject to the Master Trust Deed and any Transaction Document to which
it is a party, the Issuer Trustee shall act on all directions given to it by the
Trust Manager in accordance with the terms of the Master Trust Deed.
 
    (g) The Issuer Trustee shall properly perform the functions which are
necessary for it to perform under all Transaction Documents in respect of the
Trust.
 
4. INTEREST
 
    (A) PAYMENT DATES
 
    Each Class A Note bears interest on its Invested Amount (as defined below)
from and including 9 June 1998 or such later date as may be agreed between the
Issuer Trustee and the Managers for the issue of the Class A Notes (the "Closing
Date"). Interest in respect of the Class A Notes will be payable quarterly in
arrear on the 19th day falling in July 1998 in respect of the period from (and
including) the Closing Date to (but excluding) that date, and thereafter on each
19 April, 19 July, 19 October and 19 January (each such date a "Payment Date"
and each such three month period beginning on each of 1 April, 1 July, 1 October
and 1 January a "Quarter"). If any Payment Date would otherwise fall on a day
 
                                      II-4
<PAGE>
which is not a Business Day (as defined below), it shall be postponed to the
next day which is a Business Day (as defined below) unless it would thereby fall
into the next calendar month in which event it shall be brought forward to the
immediately preceding Business Day.
 
    "Business Day" in this Class A Condition 4 and in Class A Conditions 5 and 9
below means any day (London time) other than a Saturday, Sunday or public
holiday on which banks are open for business in Sydney, London and New York
City.
 
    The period beginning on (and including) the Closing Date and ending on (but
excluding) the first Payment Date and each successive period beginning on (and
including) a Payment Date and ending on (but excluding) the next Payment Date is
called an "Interest Period". Interest payable on a Class A Note in respect of
any Interest Period or any other period will be calculated on the basis of the
actual number of days elapsed and a 360 day year.
 
    Interest shall cease to accrue on any Class A Note from (and including):
 
    (i) the date on which the Stated Amount (as defined in Class A Condition
5(a)) of that Class A Note is reduced to zero; or
 
    (ii) if the Stated Amount on the due date for redemption is not zero, the
due date for redemption of the Class A Note, unless, upon due presentation,
payment of principal due is improperly withheld or refused, following which
interest shall continue to accrue on the Invested Amount of the Class A Note at
the rate from time to time applicable to the Class A Notes until the moneys in
respect of that Class A Note have been received by the Note Trustee or the
Principal Paying Agent and notice to that effect is given in accordance with
Class A Condition 12, or the Stated Amount of that Class A Note has been reduced
to zero.
 
    (B) INTEREST RATE
 
    The rate of interest applicable from time to time to the Class A Notes (the
"Interest Rate") will be determined by the Agent Bank on the basis of the
following paragraphs.
 
    On the second London banking day before the beginning of each Interest
Period (each an "Interest Determination Date"), the Agent Bank will determine
the rate "USD-LIBOR-BBA" as an applicable Floating Rate Option under the
Definitions of the International Swaps and Derivatives Association, Inc.
("ISDA") (the "ISDA Definitions") being the rate applicable to any Interest
Period for three-month deposits in US Dollars which appears on the Telerate Page
3750 as of 11am London time, on the Interest Determination Date. If such rate
does not appear on the Telerate Page 3750, the rate for the Interest Period will
be determined as if the Issuer Trustee and Agent Bank had specified
"USD-LIBOR-Reference Banks" as the applicable Floating Rate Option under the
ISDA Definitions. "USD-LIBOR-Reference Banks" means that the rate for an
Interest Period will be determined on the basis of the rates at which deposits
in US Dollars are offered by the Reference Banks (being four major banks in the
London interbank market) at approximately 11.00 am, London time, on the Interest
Determination Date to prime banks in the London interbank market for a period of
three months commencing on the first day of the Interest Period and in a
Representative Amount (as defined in the ISDA Definitions). The Agent Bank will
request the principal London office of each of the Reference Banks to provide a
quotation of its rate. If at least two such quotations are provided, the rate
for that Interest Period will be the arithmetic mean of the quotations. If fewer
than two quotations are provided as requested, the rate for that Interest Period
will be the arithmetic mean of the rates quoted by major banks in New York City,
selected by the Agent Bank, at approximately 11.00 am, New York City time, on
that Interest Determination Date for loans in US Dollars to leading European
banks for a period of three months commencing on the first day of the Interest
Period and in a Representative Amount, provided that on the first day of the
first Interest Period USD-LIBOR-BBA shall be an interpolated rate calculated
with reference to the period from (and including) the Closing Date to (but
excluding) the first Interest Payment Date.
 
                                      II-5
<PAGE>
    The Interest Rate applicable to the Class A Notes for such Interest Period
shall be the aggregate of (i) such Interest Rate or arithmetic mean as
determined by the Agent Bank and (ii) the margin of 0.[*]% applicable to the
Class A Notes.
 
    There is no maximum or minimum Interest Rate.
 
    (C) DETERMINATION OF INTEREST RATE AND CALCULATION OF INTEREST
 
    The Agent Bank will, as soon as practicable after 11.00 am (London time) on
each Interest Determination Date, determine the Interest Rate applicable to, and
calculate the amount of interest payable (the "Interest") for the immediately
succeeding Interest Period. The Interest is calculated by applying the Interest
Rate for the Class A Notes to the Invested Amount (as defined in Class A
Condition 5(a)) of the Class A Note on the first day of the next Interest
Period, multiplying such product by the actual number of days in the relevant
Interest Period and dividing by 360 and rounding the resultant figure down to
the nearest cent (half a cent being rounded upwards). The determination of the
Interest Rate and the Interest by the Agent Bank shall (in the absence of
manifest error) be final and binding upon all parties.
 
    (D) NOTIFICATION AND PUBLICATION OF INTEREST RATE AND INTEREST
 
    The Agent Bank will cause the Interest Rate and the Interest applicable to
each Class A Note for each Interest Period and the relevant Payment Date to be
notified to the Issuer Trustee, the Trust Manager, the Note Trustee, the Paying
Agents, and, for so long as the Class A Notes are listed on the Official List of
the London Stock Exchange Limited (the "London Stock Exchange"), the London
Stock Exchange, and will cause the same to be published in accordance with Class
A Condition 12 on or as soon as possible after the date of commencement of the
relevant Interest Period. The Interest and the relevant Payment Date so
published may subsequently be amended (or appropriate alternative arrangements
made by way of adjustment) without notice in the event of a shortening of the
Interest Period.
 
    (E) DETERMINATION OR CALCULATION BY THE NOTE TRUSTEE
 
    If the Agent Bank at any time for any reason does not determine the Interest
Rate or calculate the Interest for a Class A Note, the Note Trustee shall do so
and each such determination or calculation shall be deemed to have been made by
the Agent Bank. In doing so, the Note Trustee shall apply the foregoing
provisions of this Condition, with any necessary consequential amendments, to
the extent that, in its opinion, it can do so, and, in all other respects it
shall do so in such a manner as it shall deem fair and reasonable in all the
circumstances.
 
    (F) AGENT BANK
 
    The Issuer Trustee will procure that, so long as any of the Class A Notes
remains outstanding, there will at all times be an Agent Bank. The Issuer
Trustee reserves the right at any time to terminate the appointment of the Agent
Bank. Notice of that termination will be given to the Class A Noteholders. If
any person is unable or unwilling to continue to act as the Agent Bank, or if
the appointment of the Agent Bank is terminated, the Issuer Trustee will, with
the approval of the Note Trustee, appoint a successor Agent Bank to act as such
in its place, provided that neither the resignation nor removal of the Agent
Bank shall take effect until a successor approved by the Note Trustee has been
appointed.
 
5. REDEMPTION AND PURCHASE
 
    (A) MANDATORY REDEMPTION IN PART FROM PRINCIPAL COLLECTIONS AND
APPORTIONMENT OF PRINCIPAL COLLECTIONS BETWEEN THE CLASS A NOTES, THE CLASS B
NOTES, THE RFS CLASS A NOTES AND THE RFSS
 
    The Class A Notes shall be subject to mandatory redemption in part on any
Payment Date if on that date there are any Principal Collections (as defined
below) available to be distributed in relation to such
 
                                      II-6
<PAGE>
Class A Notes. The principal amount so redeemable in respect of each Class A
Note prior to enforcement of the Security Trust Deed (each a "Principal
Payment") on any Payment Date shall be the amount available for payment as set
out in Class A Condition 5(b) on the day which is four Business Days prior to
the Payment Date (the "Collection Determination Date") preceding that Payment
Date multiplied by the Invested Amount of the applicable Class A Note over the
total Invested Amount of all Class A Notes then outstanding (rounded down to the
nearest cent with half a cent being rounded upwards); provided always that no
Principal Payment on a Class A Note on any date may exceed the amount equal to
the Invested Amount of that Class A Note at that date less amounts charged off
as at that date, or to be charged off on the following Payment Date, as
described in Class A Condition 5(c) (that reduced amount being the "Stated
Amount" of that Class A Note).
 
    The "Invested Amount" of a Class A Note is equal to the Initial Invested
Amount (as defined herein) of such Class A Note less all payments previously
made in respect of principal in respect of such Class A Note. The "Initial
Invested Amount" of a Class A Note is its principal balance at the date of its
issuance.
 
    "Principal Collections" means, in respect of a Collection Period (as defined
below) and as applicable on any Collection Determination Date, the aggregate of:
 
    (i) all amounts received by or on behalf of the Issuer Trustee from or on
behalf of borrowers under the Loans during the Collection Period in respect of
principal, in accordance with the terms of the Loans, including principal
prepayments;
 
    (ii) all other amounts received by or on behalf of the Issuer Trustee under
or in respect of principal under the Loans and the Mortgages during that
Collection Period including:
 
    (A) any amounts recovered in respect of enforcement of Loans and Mortgages
(other than under lender's mortgage insurance), on account of principal;
 
    (B) any payments by Westpac to the Issuer Trustee on the repurchase of a
Loan under the Master Trust Deed during that Collection Period which are
attributable to principal;
 
    (C) any payments by Westpac Securities Administration Limited (in its
capacity as trustee of any other trust established under the Master Trust Deed)
(the "WST Purchaser") on the purchase by the WST Purchaser of any assets of the
Trust which are attributable to principal;
 
    (D) any Prepayment Costs (as defined in the Series Notice) applied towards
Prepayment Benefits (as defined in the Series Notice) under the Series Notice;
and
 
    (E) any Prepayment Benefit Shortfall (as defined in the Series Notice) paid
by Westpac to the Trust under the Series Notice;
 
    (iii) all amounts received by or on behalf of the Issuer Trustee during that
Collection Period from any provider of a Support Facility (as defined in the
Series Notice) (other than the Currency Swap) under that Support Facility and
which the Trust Manager determines should be accounted for to reduce any
principal loss on a Loan, being the total amount outstanding under a Loan after
applying all proceeds from the enforcement of the Loan and related Mortgages (a
"Liquidation Loss") to the extent that Liquidation Loss is attributable to
principal;
 
    (iv) all amounts received by or on behalf of the Issuer Trustee during that
Collection Period:
 
    (A) from Westpac or the WST Seller Trustee (each an "Approved Seller") in
respect of any breach of a representation, warranty or undertaking contained in
the Master Trust Deed or the Series Notice;
 
    (B) from an Approved Seller under any obligation under the Master Trust Deed
or the Series Notice to indemnify or reimburse the Issuer Trustee for any
amount;
 
    (C) from the Servicer, in respect of any breach of any representation,
warranty or undertaking contained in the Servicing Agreement; and
 
                                      II-7
<PAGE>
    (D) from the Servicer under any obligation under the Servicing Agreement to
indemnify or reimburse the Issuer Trustee for any amount,
 
    in each case, which are determined by the Trust Manager to be in respect of
principal payable under the Loans and the Mortgages;
 
    (v) any amounts in the nature of principal received by or on behalf of the
Issuer Trustee during that Collection Period pursuant to the sale of any asset
comprised in the Trust (including any amount received by the Issuer Trustee on
the issue of Notes and which was not used to purchase Loans or Mortgages, and
which the Trust Manager determines is surplus to the requirements of the Trust);
 
    (vi) (for the purposes of clause 6.11 of the Series Notice only) any amount
of Excess Available Income (as defined in the Series Notice) to be applied to
pay a Principal Charge Off or a Carryover Charge Off (as defined in the Series
Notice);
 
    (vii) any amount received by or on behalf of the Issuer Trustee during that
Collection Period as proceeds from the issue of any RFS to the extent not
applied to reimburse amounts drawn under the Redraw Facility dated [*] between
the Issuer Trustee, the Trust Manager and Westpac (the "Redraw Facility");
 
    (viii) any Excess Available Income to be applied to Principal Draws (as
defined in the Series Notice) made on a previous Payment Date;
 
    (ix) any Prepayment Calculation Adjustment (as defined in the Series Notice)
for that Collection Period;
 
    (x) any Substitution Net Transfer Amount (Principal) (as defined in the
Series Notice) received by the Trust from a WST Purchaser with respect to that
Collection Period;
 
less any amounts deducted by or paid to Westpac to reimburse Redraws funded by
Westpac for which Westpac has not previously been reimbursed. A premium
receivable by the Issuer Trustee on the entry into a replacement Currency Swap
under clause 6.26 of the Series Notice is not treated as a Principal Collection.
 
   
    "Collection Period" means, in relation to a Payment Date, the period from
(and including) the tenth day of the Quarter preceding the Quarter in which the
Payment Date occurs to (and including) the ninth day of the Quarter in which the
Payment Date occurs. The first Collection Period is the period from (but
excluding) May 6, 1998 (the "Cut-Off Date") to (and including) July 9, 1998. The
last Collection Period is the period from (but excluding) the last day of the
previous Collection Period to (and including) the termination date of the Trust.
    
 
    (B) INITIAL PRINCIPAL DISTRIBUTIONS
 
    Principal Collections will be distributed as follows on each Payment Date
before any payments in respect of the Notes:
 
    (i) first, to repay any Redraws provided by Westpac in relation to Loans to
the extent that Westpac has not previously been reimbursed in relation to those
Redraws;
 
    (ii) second, to repay all principal outstanding under the Redraw Facility on
that Payment Date;
 
    (iii) third, to allocate to Total Available Funds any Principal Draw (as
defined in the Series Notice); and
 
    (iv) fourth, to repay PARI PASSU and rateably all amounts outstanding under
the RFSs (if any).
 
    (C) PRINCIPAL ALLOCATION METHOD
 
    On each Collection Determination Date, the Trust Manager will determine the
A$ Equivalent of the aggregate of the Class B Stated Amounts divided by the sum
of (i) the A$ Equivalent of the Total Stated
 
                                      II-8
<PAGE>
Amount at that time, plus (ii) the Redraw Limit at that time, plus (iii) the
aggregate of the RFS Stated Amount at that time, plus (iv) the aggregate of the
RFS Class A Stated Amounts at that time (the "Subordinated Percentage"). The
Trust Manager will calculate the Subordinated Percentage so as to determine the
appropriate principal distribution methodology to apply for that Collection
Period, as described below.
 
    (D) APPLICABILITY OF SERIAL METHOD 1
 
    If, on any Collection Determination Date:
 
    (i) the Subordinated Percentage at the previous Collection Determination
Date was greater than or equal to twice the Initial Subordinated Percentage;
 
    (ii) that Collection Determination Date occurs on or before the third
anniversary of the Closing Date;
 
    (iii) the Total Invested Amount as at that Collection Determination Date as
a percentage of the Total Initial Invested Amount, is greater than or equal to
10%:
 
    (iv) the Average Quarterly Percentage as at that Collection Determination
Date:
 
    (A) does not exceed 2% and the Total Carryover Charge Off on that Collection
Determination Date does not exceed 30% of the Class B Initial Invested Amount;
or
 
    (B) does not exceed 4% and the Total Carryover Charge Off on such Collection
Determination Date does not exceed 10% of the Class B Initial Invested Amount;
and
 
    (v) the Stated Amounts of all Class B Notes as at that Collection
Determination Date exceeds 0.25% of the aggregate of all Initial Invested
Amounts of all Class A Notes and all Class B Notes as at the Collection
Determination Date;
 
then Principal Collections will be allocated serially in accordance with Serial
Method I set out in paragraph (e) below.
 
    (E) SERIAL METHOD 1
 
    On any Collection Determination Date, if the Trust Manager determines that
Serial Method 1 should apply, the Issuer Trustee (based on instructions from the
Trust Manager) will pay out of Principal Collections for the relevant Collection
Period which remain after the Initial Principal Distributions, on the Payment
Date following that Collection Determination Date the following amounts in the
following priority:
 
    (i) first PARI PASSU and rateably between themselves:
 
    (A) as a payment, denominated in A$, to the Currency Swap Providers under
the relevant swap confirmations relating to the Class A Notes of an amount equal
to the lesser of:
 
    (1) the Class A Forex Percentage of the sum of:
 
    (aa) the Class A Percentage of Principal Collections remaining after all
Initial Principal Distributions; and
 
    (bb) 50% of the Class B Percentage of those Principal Collections; and
 
    (2) the A$ Equivalent of the Class A Stated Amounts for all Class A Notes;
and
 
    (B) as a payment denominated in A$ to the holders of the RFS Class A Notes
(if any) of an amount equal to the lesser of:
 
    (1) the RFS Class A Forex percentage of the sum of:
 
                                      II-9
<PAGE>
    (aa) the Class A Percentage of Principal Collections remaining after all
Initial Principal Distributions; and
 
    (bb) 50% of the Class B Percentage of those Principal Collections; and
 
    (2) the RFS Class A Stated Amounts for all RFS Class A Notes (if any); and
 
    (ii) second, as a payment, denominated in A$, to the Currency Swap Providers
under the relevant swap confirmations relating to the Class B Notes of an amount
equal to 50% of the Class B Percentage of those Principal Collections remaining
after all Initial Principal Distributions.
 
    (F) APPLICABILITY OF SERIAL METHOD 2
 
    If, on any Collection Determination Date:
 
    (i) the Subordinated Percentage at the previous Collection Determination
Date was greater than or equal to twice the Initial Subordinated Percentage;
 
    (ii) that Collection Determination Date occurs after the third anniversary
of the Closing Date;
 
    (iii) the Total Invested Amount as at that Collection Determination Date, as
a percentage of the Total Initial Invested Amount, is greater than or equal to
10%;
 
    (iv) the Average Quarterly Percentage as at the Collection Determination
Date:
 
    (A) does not exceed 2% and the Total Carryover Charge Off on that Collection
Determination Date does not exceed 30% of the Class B Initial Invested Amount;
or
 
    (B) does not exceed 4% and the Total Carryover Charge Off on that Collection
Determination Date does not exceed 10% of the Class B Initial Invested Amount;
and
 
    (v) the Stated Amount of the Class B Notes as at that Collection
Determination Date exceeds 0.25% of the aggregate of all Initial Invested
Amounts of all Class A Notes and all Class B Notes and the US$ Equivalent of the
Invested Amounts of all RFS Class A Notes (if any);
 
then Principal Collections will be allocated serially in accordance with Serial
Method 2 set out in paragraph (g) below.
 
    (G) SERIAL METHOD 2
 
    On any Collection Determination Date, if the Trust Manager determines that
Serial Method 2 shall apply, the Issuer Trustee (based on instructions from the
Trust Manager) will pay out of Principal Collections for the relevant Collection
Period which remain after the Initial Principal Distributions on the Payment
Date following that Collection Determination Date in the following amounts in
the following priority:
 
    (i) first, PARI PASSU and rateably between themselves:
 
    (A) as a payment, denominated in A$, to the Currency Swap Providers under
the relevant swap confirmations relating to the Class A Notes of an amount equal
to the lesser of:
 
    (1) the Class A Forex Percentage of the Class A Percentage of Principal
Collections remaining after all Initial Principal Distributions; and
 
    (2) the A$ Equivalent of the Class A Stated Amounts for all Class A Notes;
and
 
    (B) as a payment denominated in A$ to the holders of the RFS Class A Notes
(if any) of an amount equal to the lesser of:
 
    (1) the RFS Class A Forex Percentage of the Class A Percentage of those
Principal Collections remaining after all Initial Principal Distributions: and
 
    (2) the RFS Class A Stated Amounts for all RFS Class A Notes (if any); and
 
                                     II-10
<PAGE>
    (ii) second as a payment, denominated in A$, to the Currency Swap Providers
under the relevant swap confirmations relating to the Class B Notes of an amount
equal to the Class B Percentage of those Principal Collections.
 
    (H) SEQUENTIAL METHOD
 
    On any Collection Determination Date, if the Trust Manager determines that
neither Serial Method I nor Serial Method 2 (set out in Conditions 5(d) to (g)
above) applies, the Issuer Trustee (based on instructions from the Trust
Manager) will pay out of Principal Collections for the relevant Collection
Period which remain after the Initial Principal Distributions the following
amounts in the following priority:
 
    (I) FIRST PARI PASSU and rateably between themselves:
 
    (A) as a payment, denominated in A$, to the Currency Swap Providers under
the relevant swap confirmations relating to the Class A Notes of an amount equal
to the lesser of:
 
    (1) the Class A Forex Percentage of the amount available for distribution
under this paragraph (i) after all Initial Principal Distributions; and
 
    (2) the A$ Equivalent of the Class A Stated Amounts for all Class A Notes;
and
 
    (B) as a payment, denominated in A$, to the holders of the RFS Class A Notes
(if any) of an amount equal to the lesser of:
 
    (1) the RFS Class A Forex Percentage of the amount available for
distribution under this paragraph (i) after all Initial Principal Distributions;
and
 
    (2) the RFS Class A Stated Amounts for all RFS Class A Notes (if any); and
 
    (ii) second, as a payment, denominated in A$, to the Currency Swap Providers
under the relevant swap confirmations relating to the Class B Notes of an amount
equal to the lesser of:
 
    (A) the amount available for distribution under this paragraph (ii) after
the application of paragraph (i); and
 
    (B) the A$ Equivalent of the Class B Stated Amounts for all Class B Notes.
 
    (I) GENERAL
 
    No amount of principal will be paid to a Noteholder in excess of the Stated
Amount applicable to the Notes held by that Noteholder.
 
    (J) DISTRIBUTION OF EXCESS AVAILABLE INCOME
 
    On each Collection Determination Date Excess Available Income for the
Collection Period relating to that Collection Determination Date will be applied
in the following order of priority:
 
    (i) to reimburse Principal Charge Offs for that Collection Period;
 
    (ii) PARI PASSU and rateably between themselves (based on the Stated Amount
of the RFSs (if any), the Stated Amount of the RFS Class A Notes (if any), the
Principal Outstanding under the Redraw Facility and the A$ Equivalent of the
Stated Amount of the Class A Notes):
 
    (A) as a payment to the RFSs (if any) in or towards reinstating the Stated
Amount of the RFSs, to the extent of any Carryover RFS Charge Offs;
 
    (B) as a payment to the RFS Class A Notes (if any) in or towards reinstating
the Stated Amount of the RFS Class A Notes, to the extent of any Carryover RFS
Class A Charge Offs;

    (L) CHARGE OFFS
 
    If the Principal Charge Offs (as defined in the Series Notice) for any
Collection Period exceed the Excess Available Income (as defined in the Series
Notice) calculated on the Collection Determination Date for that Collection
Period, the Trust Manager must, on and with effect from the Payment Date
immediately following the end of the Collection Period:
 
    (i) reduce PARI PASSU the Class B Stated Amount of each of the Class B Notes
by the US$ Equivalent of the amount of that excess which is attributable to each
Class B Note until the Class B Stated Amount is zero; and
 
    (ii) if the Class B Stated Amount is zero and any amount of that excess has
not been applied under paragraph (i), reduce PARI PASSU and rateably as between
themselves (based on the Stated Amount of the RFSs (if any), the Principal
Outstanding under the Redraw Facility, the Stated Amount of the RFS Class A
Notes (if any) and the A$ Equivalent of the Stated Amount of the Class A Notes):
 
    (A) the Class A Stated Amount on each of the Class A Notes by the US$
Equivalent of the balance of that excess which is attributable to each Class A
Note until the Class A Stated Amount of that Class A Note is zero;
 
                                     II-12
<PAGE>
    (B) the RFS Class A Stated Amount on each of the RFS Class A Notes (if any)
by the balance of that excess which is attributable to each RFS Class A Note
until the RFS Class A Stated Amount of that RFS Class A Note is zero;
 
    (C) the RFS Stated Amount on each of the RFSs (if any) by the balance of
that excess which is attributable to each RFS until the RFS Stated Amount is
zero: and
 
    (D) the principal outstanding under the Redraw Facility by the balance of
that excess until the Principal Outstanding is zero.
 
    (M) CALCULATION OF PRINCIPAL PAYMENTS, STATED AMOUNT AND BOND FACTOR
 
    (i) On each Collection Determination Date, the Trust Manager shall
determine:
 
    (A) the amount of any Principal Payment in respect of each Class A Note on
the Payment Date following that Collection Determination Date;
 
   
    (B) the Stated Amount and Invested Amount of each Class A Note as of the
first day of the next following Interest Period (after deducting any Principal
Payment due to be made in respect of each Class A Note on the next Payment
Date); and
    
 
    (C) the fraction in respect of each Class A Note expressed as a decimal to
the seventh point (the "Bond Factor" of which the numerator is the aggregate of
the Invested Amount of all Class A Notes at that date less all Principal
Payments to be made on the following Payment Date, and the denominator is the
Initial Invested Amount of the Class A Notes.
 
    (ii) The Trust Manager will notify the Note Trustee, the Principal Paying
Agent, the Agent Bank and (for so long as the Class A Notes are listed on the
London Stock Exchange) the London Stock Exchange by not later than the
Collection Determination Date immediately preceding the relevant Payment Date of
each determination of a Principal Payment, Invested Amount, Stated Amount and
Bond Factor and will immediately cause details of each of those determinations
to be published in accordance with Condition 12. If no Principal Payment is due
to be made on the Class A Notes on any Payment Date a notice to this effect will
be given to the Class A Noteholders in accordance with Class A Condition 12.
 
    (iii) If the Trust Manager does not at any time for any reason determine a
Principal Payment, the Invested Amount, the Stated Amount or the Bond Factor
applicable to Class A Notes in accordance with this paragraph, the Principal
Payment, Invested Amount, the Stated Amount and the Bond Factor shall be
determined by the Note Trustee in accordance with this paragraph and paragraph
(i) above (but based on the information in its possession) and each such
determination or calculation shall be deemed to have been made by the Trust
Manager.
 
    (iv) The Trust Manager will deliver to the Principal Paying Agent a
quarterly servicing report as set forth in clause 11 of the Note Trust Deed.
 
    (N) REDEMPTION FOR TAXATION OR OTHER REASONS
 
    If the Trust Manager satisfies the Issuer Trustee and the Note Trustee
immediately prior to giving the notice referred to below that either (i) on the
next Payment Date the Issuer Trustee would be required to deduct or withhold
from any payment of principal or interest in respect of the Class A Notes any
amount for or on account of any present or future taxes, duties, assessments or
governmental charges of whatever nature imposed, levied, collected, withheld or
assessed by the Commonwealth of Australia or any of its political sub-divisions
or any of its authorities or (ii) the total amount payable in respect of
interest in relation to the Loans for a Collection Period ceases to be
receivable (whether or not actually received) by the Issuer Trustee during such
Collection Period by reason of any present or future taxes, duties, assessments
or governmental charges of whatever nature imposed, levied, collected, withheld
or assessed by the Commonwealth of Australia or any of its political
sub-divisions or any of its authorities, the Issuer Trustee must, when so
directed by the Trust Manager (at any time at the Trust Manager's option)
(provided
 
                                     II-13
<PAGE>
that the Issuer Trustee will be in a position on such Payment Date to discharge
(and will so certify to the Issuer Trustee and Note Trustee) all its liabilities
in respect of the Class A Notes and any amounts required under the Security
Trust Deed to be paid in priority to or PARI PASSU with the Class A Notes), upon
having given not more than 60 nor less than 30 days' notice to the Class A
Noteholders in accordance with Class A Condition 12 redeem all, but not some
only, of the Class A Notes at their Invested Amount (or at the option of the
holders of 75% of the aggregate Invested Amount of Class A Notes at the time, at
their Stated Amount), together with accrued interest to the date of redemption
on any subsequent Payment Date, provided that the holders of 75% of the
aggregate Invested Amount of Class A Notes at the time may elect, and shall
notify the Issuer Trustee and the Trust Manager, that they do not require the
Issuer Trustee to redeem the Class A Notes in the circumstances described above.
 
    (O) OPTIONAL REDEMPTION IN WHOLE
 
    On any Payment Date, and upon giving no more than 60 nor less than 30 days'
notice to the Note Trustee and the Security Trustee, on which the aggregate
principal outstanding of the Loans is less than 10% of the aggregate principal
outstanding of the Loans at the Cut-Off Date, the Issuer Trustee may redeem all
(but not some only) of the Class A Notes at their Stated Amount.
 
    (P) REDEMPTION ON MATURITY
 
    If not otherwise redeemed, the Class A Notes will be redeemed at their
Stated Amount on the Payment Date falling in December 2029.
 
    (Q) CANCELLATION
 
    All Class A Notes redeemed in full pursuant to the foregoing provisions will
be cancelled forthwith, and may not be resold or reissued.
 
    (R) CERTIFICATION
 
    For the purposes of any redemption made pursuant to this Condition 5 the
Note Trustee may rely upon an officer's certificate under the Note Trust Deed
from the Trust Manager on behalf of the Issuer Trustee certifying or stating the
opinion of each person signing such certificate as:
 
    (i) to the fair value (within 90 days of such release) of the property or
securities proposed to be released from the Security Trust Deed;
 
    (ii) that in the opinion of such person the proposed release will not impair
the security under the Security Trust Deed in contravention of the provisions of
the Security Trust Deed or the Note Trust Deed;
 
    (iii) that the Issuer Trustee will be in a position to discharge all its
liabilities in respect of the relevant Class A Notes; and
 
    (iv) any amounts required under the Security Trust Deed to be paid in
priority to or PARI PASSU with those Class A Notes,
 
    and such officer's certificate shall be conclusive and binding on the Issuer
Trustee, the Note Trustee and the holders of those Class A Notes.

6. PAYMENTS
 
    (A) METHOD OF PAYMENT
 
    Any instalment of interest or principal, payable on any Class A Note which
is punctually paid or duly provided for by the Issuer Trustee to the Principal
Paying Agent on the applicable Payment Date or Maturity Date shall be paid to
the person in whose name such Class A Note is registered on the Record Date, by
cheque mailed first-class, postage prepaid, to such person's address as it
appears on the Note Register on such Record Date, except that, unless Definitive
Notes have been issued pursuant to clause 3.3 of the Note Trust Deed, with
respect to Class A Notes registered on the Record Date in the name of the
nominee of DTC (initially, such nominee to be Cede & Co.), payment will be made
by wire transfer in immediately available funds to the account designated by
such nominee and except for the final instalment of principal payable with
respect to such Class A Note on a Payment Date or Maturity Date.
 
    (B) INITIAL PRINCIPAL PAYING AGENT
 
    The initial Principal Paying Agent is Morgan Guaranty Trust Company of New
York, London Branch at its office at 60 Victoria Embankment, London EC4Y 0JP.
 
    (C) PAYING AGENTS
 
    The Issuer Trustee (or the Trust Manager on its behalf after advising the
Issuer Trustee thereof) may at any time (with the previous written approval of
the Note Trustee) vary or terminate the appointment of any Paying Agent and
appoint additional or other Paying Agents, provided that it will at all times
maintain a Paying Agent having a specified office in London and in New York
City. Notice of any such termination or appointment and of any change in the
office through which any Paying Agent will act will be given in accordance with
Class A Condition 12.
 
    (D) DUE DATE FOR REDEMPTION
 
    If the due date for redemption in full of a Class A Note is not a Payment
Date, the interest accrued in respect of the period from the preceding Payment
Date (or from the Closing Date as the case may be) shall be payable only against
presentation or surrender of the relevant Class A Note.
 
    (E) PAYMENTS ON BUSINESS DAYS
 
    If the due date for payment of any amount of principal or Interest in
respect of any Class A Note is not a Business Day then payment will not be made
until the next succeeding Business Day and the holder thereof shall not be
entitled to any further interest or other payment in respect of that delay. In
this Condition 6 the expression "Business Day" means any day (other than a
Saturday, Sunday or a public holiday) on which banks are open for business in
the place where the specified office of the Paying Agent is situated and, in the
case of payment by transfer to a US dollar account, in New York City and prior
to any exchange of the Book-Entry Note (in respect of the Class A Notes) for any
definitive Class A Notes, on which DTC is open for business.
 
    (F) INTEREST
 
    If Interest is not paid in respect of a Class A Note on the date when due
and payable (other than because the due date is not a Business Day), that unpaid
Interest shall itself bear interest at the Interest Rate applicable from time to
time to the Class A Notes until the unpaid interest, and interest on it, is
available for payment and notice of that availability has been duly given in
accordance with Class A Condition 12.
 
                                     II-15
<PAGE>
7. TAXATION
 
    All payments in respect of the Class A Notes will be made without
withholding or deduction for, or on account of, any present or future taxes,
duties or charges of whatsoever nature unless the Issuer Trustee or any Paying
Agent is required by applicable law to make any such payment in respect of the
Class A Notes subject to any withholding or deduction for, or on account of, any
present or future taxes, duties or charges of whatsoever nature. In that event
the Issuer Trustee or that Paying Agent (as the case may be) shall make such
payment after such withholding or deduction has been made and shall account to
the relevant authorities for the amount so required to be withheld or deducted.
Neither the Issuer Trustee nor any Paying Agent will be obliged to make any
additional payments to Class A Noteholders in respect of that withholding or
deduction.
 
8. PRESCRIPTION
 
    A Class A Note shall become void in its entirety unless surrendered for
payment within ten years of the Relevant Date in respect of any payment thereon
the effect of which would be to reduce the Stated Amount of that Class A Note to
zero. After the date on which a Class A Note becomes void in its entirety, no
claim may be made in respect of it.
 
    As used in these Conditions, the "Relevant Date" means the date on which a
payment first becomes due but, if the full amount of the money payable has not
been received by the Principal Paying Agent or the Note Trustee on or prior to
that date, it means the date on which, the full amount of such money having been
so received, notice to that effect is duly given in accordance with Class A
Condition 12.
 
9. EVENTS OF DEFAULT
 
    Each of the following is an "Event of Default":
 
    (a) the Issuer Trustee fails to pay:
 
    (i) any interest within 10 Business Days of the Payment Date on which the
interest was due to be paid to Class A Noteholders, Class B Noteholders or

    (b) the Issuer Trustee fails to perform or observe any other provisions
(other than an obligation referred to in paragraph (a)) of a Transaction
Document (other than the Underwriting Agreement) where such failure will have a
material and adverse affect on the amount of any payment to be made to any
Noteholder, or will materially and adversely affect the timing of such payment,
and that default (if in the opinion of the Security Trustee capable of remedy
(that opinion, being subject to the approval of the Note Trustee in accordance
with the provisions of the Security Trust Deed) is not remedied within 30 days
(or such longer period as may be specified in the notice, that longer period
having been approved by the Note Trustee, for so long as amounts outstanding
under the Offered Notes are 75% of the Secured Money) after written notice from
the Security Trustee requiring the failure to be remedied.
 
    (c) any of the following occurs in relation to the Issuer Trustee (in its
personal capacity or as Trustee of the Trust):

    IN THE EVENT THAT THE SECURITY CONSTITUTED BY THE SECURITY TRUST DEED
BECOMES ENFORCEABLE FOLLOWING AN EVENT OF DEFAULT UNDER THE NOTES ANY FUNDS
RESULTING FROM THE REALIZATION OF SUCH SECURITY SHALL BE APPLIED IN ACCORDANCE
WITH THE ORDER OF PRIORITY OF PAYMENTS AS STATED IN THE SECURITY TRUST DEED.
 
10. ENFORCEMENT
 
    (a) At any time after an Event of Default occurs, the Security Trustee may,
with the prior written consent of the Note Trustee in accordance with the
provisions of the Security Trust Deed and shall, if so directed by (a) the Note
Trustee alone, where the Note Trustee is the only Voting Mortgagee, or otherwise
(b) an Extraordinary Resolution (being 75% of votes capable of being cast by
Voting Mortgagees present or in person or by proxy of the relevant meeting or a
written resolution signed by all Voting Mortgagees) of
 
                                     II-17
<PAGE>
the Voting Mortgagees (which includes the Note Trustee on behalf of Noteholders,
but not the Noteholders themselves), declare the Class A Notes immediately due
and payable and enforce the Security Trust Deed. If an Extraordinary Resolution
of Voting Mortgagees referred to in sub-paragraph (b) above elects not to direct
the Security Trustee to enforce the Security Trust Deed, in circumstances where
the Security Trustee could enforce, the Note Trustee may nonetheless, and shall
at the direction of the Class A Noteholders, direct the Security Trustee to
enforce the Security Trust Deed on behalf of the Noteholders.
 
    "Voting Mortgagee" means:
 
    (a) for so long as the amounts outstanding under the Class A Notes and the
Class B Notes are 75% or more of all amounts secured by the Security Trust Deed,
the Note Trustee alone; and
 
    (b) at any other time:
 
    (i) the Note Trustee, acting on behalf of the Noteholders under the Note
Trust Deed and the Security Trust Deed: and
 
    (ii) each other Mortgagee under the Security Trust Deed (other than the
Noteholders).
 
    Subject to being indemnified in accordance with the Security Trust Deed, the
Security Trustee shall take all action necessary to give effect to any direction
by the Note Trustee where it is the only Voting Mortgagee or to any
Extraordinary Resolution of the Voting Mortgagees and shall comply with all
directions given by the Note Trustee where it is the only Voting Mortgagee or
contained in or given pursuant to any Extraordinary Resolution of the Voting
Mortgagees in accordance with the Security Trust Deed.
 
    No Noteholder is entitled to enforce the Security Trust Deed or to appoint
or cause to be appointed a receiver to any of the assets secured by the Security
Trust Deed or otherwise to exercise any power conferred by the terms of any
applicable law on chargees except as provided in the Security Trust Deed.
 
    (b) If any of the Class A Notes remains outstanding and are due and payable
otherwise than by reason of a default in payment of any amount due on the Class
A Notes, the Note Trustee must not vote under the Security Trust Deed to, or
otherwise direct the Security Trustee to, dispose of the Mortgaged Property
unless either:
 
    (i) a sufficient amount would be realised to discharge in full all amounts
owing to the Class A Noteholders and any other amounts payable by the Issuer
Trustee ranking in priority to or PARI PASSU with the Class A Notes; or
 
    (ii) the Note Trustee is of the opinion, reached after considering at any
time and from time to time the advice of a merchant bank or other financial
adviser selected by the Note Trustee, that the cash flow receivable by the
Issuer Trustee (or the Security Trustee under the Security Trust Deed) will not
(or that there is a significant risk that it will not) be sufficient, having
regard to any other relevant actual, contingent or prospective liabilities of
the Issuer Trustee, to discharge in full in due course all the amounts referred
to in paragraph (i).
 
    (c) Neither the Note Trustee nor the Security Trustee will be liable for any
decline in the value, nor any loss realised upon any sale or other dispositions
made under the Security Trust Deed, of any Mortgaged Property or any other
property which is charged to the Security Trustee by any other person in respect
of or relating to the obligations of the Issuer Trustee or any third party in
respect of the Issuer Trustee or the Class A Notes or relating in any way to the
Mortgaged Property. Without limitation, neither the Note Trustee nor the
Security Trustee shall be liable for any such decline or loss directly or
indirectly arising from its acting, or failing to act, as a consequence of an
opinion reached by it.
 
    (d) The Note Trustee shall not be bound to vote under the Security Trust
Deed, or otherwise direct the Security Trustee under the Security Trust Deed or
to take any proceedings, actions or steps under, or any other proceedings
pursuant to or in connection with the Security Trust Deed, the Note Trust Deed,
any
 
                                     II-18
<PAGE>
Class A Notes, unless directed or requested to do so by Noteholders holding at
least 75% of the aggregate Invested Amount of Class A Notes or Class B Notes (as
the case may be) at the time; and then only if the Note Trustee is indemnified
to its satisfaction against all action, proceedings, claims and demands to which
it may render itself liable and all costs, charges, damages and expenses which
it may incur by so doing.
 
    (e) Only the Security Trustee may enforce the provisions of the Security
Trust Deed and neither the Note Trustee nor any holder of a Class A Note is
entitled to proceed directly against the Issuer Trustee to enforce the
performance of any of the provisions of the Security Trust Deed, the Class A
Notes (including these Class A Conditions).
 
    (f) The rights, remedies and discretions of the Class A Noteholders under
the Security Trust Deed including all rights to vote or give instructions or
consent can only be exercised by the Note Trustee on behalf of the Class A
Noteholders in accordance with the Security Trust Deed. The Security Trustee may
rely on any instructions or directions given to it by the Note Trustee as being
given on behalf of the Class A Noteholders from time to time and need not
enquire whether the Note Trustee or the Noteholders from time to time have
complied with any requirements under the Note Trust Deed or as to the
reasonableness or otherwise of the Note Trustee. The Security Trustee is not
obliged to take any action, give any consent or waiver or make any determination
under the Security Trust Deed without being directed to do so by the Note
Trustee or the Voting Mortgagees in accordance with the Security Trust Deed.
 
    UPON ENFORCEMENT OF THE SECURITY CREATED BY THE SECURITY TRUST DEED, THE NET
PROCEEDS THEREOF MAY BE INSUFFICIENT TO PAY ALL AMOUNTS DUE ON REDEMPTION TO THE
NOTEHOLDERS. THE PROCEEDS FROM ENFORCEMENT (WHICH WILL NOT INCLUDE AMOUNTS
REQUIRED BY LAW TO BE PAID TO THE HOLDER OF ANY PRIOR RANKING SECURITY INTEREST,
THE PROCEEDS OF OR AMOUNTS CREDITED TO THE COLLATERAL ACCOUNT UNDER THE
LIQUIDITY FACILITY AGREEMENT (AS DEFINED IN THE MASTER TRUST DEED) AND PAYABLE
TO THE LIQUIDITY FACILITY PROVIDER (AS DEFINED IN THE MASTER TRUST DEED) AND THE
PROCEEDS OF CASH COLLATERAL LODGED WITH AND PAYABLE TO A SWAP PROVIDER OR OTHER
PROVIDER OF A SUPPORT FACILITY (AS DEFINED IN THE MASTER TRUST DEED)) WILL BE
APPLIED IN THE ORDER OF PRIORITY AS SET OUT IN THE SECURITY TRUST DEED. ANY
CLAIMS OF NOTEHOLDERS REMAINING AFTER REALIZATION OF THE SECURITY AND
APPLICATION OF THE PROCEEDS AS AFORESAID SHALL, EXCEPT IN CERTAIN LIMITED
CIRCUMSTANCES, BE EXTINGUISHED.
 
11. REPLACEMENTS OF CLASS A NOTES
 
    If any Class A Note is lost, stolen, mutilated, defaced or destroyed, it may
be replaced at the specified office of the Principal Paying Agent upon payment
by the claimant of the expenses incurred in connection with that replacement and
on such terms as to evidence and indemnity as the Issuer Trustee may reasonably
require. Mutilated or defaced Class A Notes must be surrendered before
replacements will be issued.
 
12. NOTICES
 
    All notices, other than notices given in accordance with the following
paragraph, to Class A Noteholders shall be deemed given if in writing and
mailed, first-class, postage prepaid to each Class A Noteholder, at his or her
address as it appears on the Note Register, not later than the latest date, and
not earlier than the earliest date, prescribed for the giving of such notice. In
any case where notice to Class A Noteholders is given by mail, neither the
failure to mail such notice nor any defect in any notice so mailed to any
particular Class A Noteholder shall affect the sufficiency of such notice with
respect to other Class A Noteholders, and any notice that is mailed in the
manner herein provided shall conclusively be presumed to have been duly given.
 
    A notice may be waived in writing by the relevant Class A Noteholder, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Class A Noteholders shall be filed with the Note
Trustee but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such a waiver.
 
                                     II-19
<PAGE>
    Any such notice shall be deemed to have been given on the date such notice
is deposited in the mail.
 
    In case, by reason of the suspension of regular mail services as a result of
a strike, work stoppage or similar activity, it shall be impractical to mail
notice of any event to Class A Noteholders when such notice is required to be
given, then any manner of giving such notice as the Trustee shall direct the
Note Trustee shall be deemed to be a sufficient giving of such notice.
 
    Any notice specifying a Payment Date, an Interest Rate, Interest payable, a
Principal Payment (or the absence of a Principal Payment), an Invested Amount, a
Stated Amount or a Bond Factor shall be deemed to have been duly given if the
information contained in such notice appears on the relevant page of the Reuters
Screen or such other similar electronic reporting service as may be approved by
the Note Trustee and notified to Class A Noteholders (the "Relevant Screen").
Any such notice shall be deemed to have been given on the first date on which
such information appeared on the Relevant Screen. If it is impossible or
impracticable to give notice in accordance with this paragraph then notice of
the matters referred to in this Condition shall be given in accordance with the
preceding paragraph.
 
    The Principal Paying Agent shall deliver a quarterly servicing report for
each Collection Period to each Class A Noteholder on the Notice date relating to
such Collection Period in the method provided in the first paragraph of this
Condition 12.
 
13. MEETINGS OF VOTING MORTGAGEES AND VOTES OF CLASS A NOTEHOLDERS;
  MODIFICATIONS; CONSENTS; WAIVER
 
    The Security Trust Deed contains provisions for convening meetings of the
Voting Mortgagees to, INTER ALIA, enable the Voting Mortgagees to direct or
consent to the Security Trustee taking or not taking certain actions under the
Security Trust Deed, for example to enable the Voting Mortgagees to direct the
Security Trustee to enforce the Security Trust Deed.
 
    For so long as the amounts outstanding under the Notes are 75% or more of
all amounts secured by the Security Trust Deed, the Note Trustee may direct the
Security Trustee to do any act or thing which the Security Trustee is required
to do, or may only do, at the direction of an Extraordinary Resolution of the
Voting Mortgagees.
 
    Neither the Security Trustee nor the Trust Manager may call a meeting of
Voting Mortgagees without the Note Trustee's consent, if the amounts outstanding
under the Notes are 75% or more of all amounts secured by the Security Trust
Deed.
 
    The Note Trust Deed contains provisions for the Class A Noteholders to
consider any matter affecting their interests. In general, the holders of a
majority of the aggregate Invested Amount of the Class A Notes may take or
consent to any action permitted to be taken by Class A Noteholders under the
Note Trust Deed. Notwithstanding the foregoing, the consent of holders of 75% of
the aggregate Invested Amount of the Class A Notes shall be required to (i)
direct the Note Trustee to direct the Security Trustee to enforce the security
under the Note Trust Deed, (ii) override any waiver by the Note Trustee of a
breach of any provisions of the Transaction Documents or an Event of Default,
(iii) alter, add, or modify the terms and conditions of the Class A Notes or the
provisions of any of the Transaction Documents if such alteration, addition or
modification is, in the opinion of the Note Trustee, materially prejudicial or
likely to be materially prejudicial to the Offered Noteholders as a whole or the
Class A Noteholders, which shall include any modification to the date of
maturity of the Class A Notes or a modification which would have the effect of
postponing any day for payment of interest in respect of any Class A Notes,
reducing or cancelling the amount of principal payable in respect of any Class A
Notes or the rate of interest applicable to any Class A Notes or altering the
percentage of the aggregate Invested Amount required to consent to any action or
altering the currency of payment of any Class A Notes or an alteration of the
date or priority of redemption of the Class A Notes (any such modification being
referred to below as a "Basic Terms Modification"). The Note Trust Deed contains
provisions limiting the powers of the Class B Noteholders, INTER ALIA, to
request or direct the Note Trustee to take any action that would be materially
prejudicial to the interests of the Class A Noteholders. Except in certain
circumstances, the Note Trust Deed imposes no
 
                                     II-20
<PAGE>
such limitations on the powers of the Class A Noteholders, the exercise of which
will be binding on the Class B Noteholders, irrespective of the effect on the
Class B Noteholders' interests. Any action taken by the requisite percentage of
the Invested Amount of the Class A Noteholders shall be binding on all Class A
Noteholders (both present and future).
 
    Pursuant to the terms of the Note Trust Deed, the Note Trustee may agree,
without the consent of the Class A Noteholders, among other things, (i) to any
modification (except a Basic Terms Modification) of, or to the waiver or
authorisation of any breach or proposed breach of the Class A Notes (including
these Conditions), or any of the Transaction Documents which is not, in the
opinion of the Note Trustee materially prejudicial to the interests of the Class
A Noteholders or (ii) to any modification of the Class A Notes (including these
Conditions, or any of the Transaction Documents which, in the Note Trustee's
opinion, is to correct a manifest error or is of a formal, minor or technical
nature. The Note Trustee may also, without the consent of the Class A
Noteholders, determine that any Event of Default or any condition, event or act
which with the giving of notice and/or lapse of time and/or the issue of a
certificate would constitute an Event of Default shall not, or shall not subject
to specified conditions, be treated as such. Any such modification, waiver,
authorisation or determination shall be binding on the Class B Noteholders and,
unless the Note Trustee agrees otherwise, any such modification shall be
notified to the Class A Noteholders in accordance with Class A Condition 12 as
soon as practicable thereafter.
 
14. INDEMNIFICATION AND EXONERATION OF THE NOTE TRUSTEE AND THE SECURITY TRUSTEE
 
    The Note Trust Deed contains provisions for the indemnification of the Note
Trustee and for its relief from responsibility, including provisions relieving
it from taking proceedings to realise the security and to obtain repayment of
the Class A Notes unless indemnified to its satisfaction. Each of the Note
Trustee and the Security Trustee is entitled to enter into business transactions
with the Issuer Trustee and/or any other party to the Relevant Documents without
accounting for any profit resulting from such transactions. Neither the Security
Trustee nor the Note Trustee will be responsible for any loss, expense or
liability which may be suffered as a result of any assets secured by the
Security Trust Deed, Mortgaged Property or any deeds or documents of title
thereto, being uninsured or inadequately insured or being held by or to the
order of the Servicer or any of its affiliates or by clearing organisations or
their operators or by any person on behalf of the Note Trustee.
 
15. LIMITATION OF LIABILITY OF THE ISSUER TRUSTEE
 
    (A) GENERAL
 
    Clause 33 of the Master Trust Deed applies to the obligations and
liabilities of the Issuer Trustee in relation to this Class A Note.
 
    (B) LIABILITY OF TRUSTEE LIMITED TO ITS RIGHT OF INDEMNITY
 
    (i) This Class A Note applies to the Issuer Trustee only in its capacity as
trustee of the Trust and in no other capacity. A liability arising under or in
connection with this Class A Note or the Trust can be enforced against the
Issuer Trustee only to the extent to which it can be satisfied out of property
of the Trust out of which the Issuer Trustee is actually indemnified for the
liability. This limitation of the Issuer Trustee's liability applies despite any
other provision of this Class A Note or any other Transaction Document and
extends to all liabilities and obligations of the Issuer Trustee in any way
connected with any representation, warranty, conduct, omission, agreement or
transaction related to this Class A Note or the Trust.
 
    (ii) None of the Note Trustee or the Class A Noteholders may take action
against the Issuer Trustee in any capacity other than as trustee of the Trust or
seek the appointment of a receiver (except under the Security Trust Deed), or a
liquidator, an administrator or any similar person to the Issuer Trustee or
prove in any liquidation, administration or arrangements of or affecting the
Issuer Trustee.
 
                                     II-21
<PAGE>
    (iii) The provisions of this Condition 15 shall not apply to any obligation
or liability of the Issuer Trustee to the extent that it is not satisfied
because under a Transaction Document or by operation of law there is a reduction
in the extent of the Issuer Trustee's indemnification out of the Trust Assets as
a result of the Issuer Trustee's fraud, negligence or breach of trust.
 
    (iv) It is acknowledged that the Trust Manager, the Servicer, each Paying
Agent, the Agent Bank and the Note Trustee (each a "Relevant Party") are
responsible under the Transaction Documents for performing a variety of
obligations relating to the Trust. No act or omission of the Issuer Trustee
(including any related failure to satisfy its obligations under this Class A
Note or a Transaction Document) will be considered fraud, negligence or breach
of trust of the Issuer Trustee for the purpose of sub-paragraph (iii) of this
Condition 15 to the extent to which the act or omission was caused or
contributed to by any failure by any Relevant Party or any other person who
provides services in respect of the Trust (other than a person who has been
delegated or appointed by the Issuer Trustee and for whom the Issuer Trustee is
responsible under the Transaction Documents, other than a Relevant Party) to
fulfil its obligations relating to the Trust or by any other act or omission of
a Relevant Party or any other person who provides services in respect of the
Trust (other than a person who has been delegated or appointed by the Issuer
Trustee and for whom the Issuer Trustee is responsible under the Transaction
Documents, other than a Relevant Party).
 
    (v) No attorney, agent, receiver or receiver and manager appointed in
accordance with a Transaction Document (including without limitation a Relevant
Party) has authority to act on behalf of the Issuer Trustee in a way which
exposes the Issuer Trustee to any personal liability and no act or omission of
any such person will be considered fraud, negligence or breach of trust of the
Issuer Trustee for the purpose of sub-paragraph (iii), if the Issuer Trustee has
exercised reasonable care in the selection and supervision of such a person.
 
16. GOVERNING LAW
 
    The Class A Notes and the Relevant Documents (other than the Security Trust
Deed which is governed by the laws of the Australian Capital territory and the
Currency Swap with Morgan Guaranty Trust Company of New York, London Office,
which is governed by the laws of England) are governed by, and shall be
construed in accordance with, the laws of New South Wales, Australia.
 
   
SUMMARY OF PROVISIONS RELATING TO THE CLASS A NOTES WHILE IN BOOK ENTRY FORM
    
 
   
    The Class A Notes will initially be represented by typewritten book-entry
notes (the Book-Entry Class A Notes"), without coupons, in the principal amount
of US$1,372,700,000. The Book-Entry Class A Notes will be deposited with the
Common Depositary for DTC on or about the Closing Date. Upon deposit of the
Book-Entry Class A Notes with the Common Depositary, DTC will credit each
investor in the Class A Notes with a principal amount of Class A Notes for which
it has subscribed and paid.
    
 
   
    The Book-Entry Class A Note will be exchangeable for definitive Class A
Notes in certain circumstances described below.
    
 
   
    Each person who is shown in the Note Register as the holder of a particular
principal amount of Class A Notes will be entitled to be treated by the Issuer
Trustee and the Note Trustee as a holder of such principal amount of Class A
Notes and the expression "Class A Noteholder" shall be construed accordingly,
but without prejudice to the entitlement of the holder of the Book-Entry Class A
Note to be paid principal and interest thereon in accordance with its terms.
Such persons shall have no claim directly against the Issuer Trustee in respect
of payment due on the Class A Notes for so long as the Class A Notes are
represented by a Book-Entry Class A Note and the relevant obligations of the
Issuer Trustee will be discharged by payment to the registered holder of the
Book-Entry Class A Note in respect of each amount so paid.
    
 
                                     II-22
<PAGE>
    (A) PAYMENTS
 
   
    Interest and principal on each Book-Entry Class A Note will be payable by
the Principal Paying Agent to the Common Depositary provided that no payment of
interest may be made by the Issuer Trustee or any Paying Agent in the
Commonwealth of Australia or its possessions or into a bank account or to an
address in the Commonwealth of Australia or its possessions.
    
 
    Each of the persons appearing from time to time as the beneficial owner of a
Class A Note will be entitled to receive any payment so made in respect of that
Class A Note in accordance with the respective rules and procedures of DTC. Such
persons will have no claim directly against the Issuer Trustee in respect of
payments due on the Class A Notes which must be made by the holder of the
relevant Book-Entry Class A Note, for so long as such Book-Entry Class A Note is
outstanding.
 
   
    A record of each payment made on a Book-Entry Class B Note, distinguishing
between any payment of principal and any payment of interest, will be recorded
in the Note Register by the Principal Paying Agent and such record shall be
prima facie evidence that the payment in question has been made.
    
 
    (B) EXCHANGE
 
    The Book-Entry Class A Note will be exchangeable for definitive Class A
Notes only if:
 
   
(a) the Trust Manager advises the Principal Paying Agent in writing that the
    Clearing Agency is no longer willing or able properly to discharge its
    responsibilities with respect to the Class A Notes or the Clearing Agency
    ceases to carry on business, and the Trust Manager is unable to located a
    qualified successor;
    
 
(b) the Issuer Trustee, at the direction of the Trust Manager (at the Trust
    Manager's option) advises the Principal Paying Agent in writing that the
    book entry system through the Clearing Agency is or is to be terminated; or
 
(c) after the occurrence of an Event, of Default the Class A Note Owner's
    representing beneficial interests aggregating to at least a majority of the
    aggregate Invested Amount of the Class A Notes advise the Principal Paying
    Agent and Issuer Trustee through the Clearing Agency in writing that the
    continuation of a book entry system through the Clearing Agency is no longer
    in the best interest of the Note Owners,
 
   
then the Principal Paying Agent shall notify all Class A Note Owners and the
Issuer Trustee of the occurrence of any such event and of the availability of
Definitive Notes to Class A Note Owners requesting the same. Upon the surrender
of the Book-Entry Notes to the Issuer Trustee by the Clearing Agency, and the
delivery by the Clearing Agency of the relevant registration instructions to the
Issuer Trustee, the Issuer Trustee shall execute and procure the Principal
Paying Agent to authenticate the Definitive Notes in accordance with the
instructions of the Clearing Agency.
    
 
    (C) NOTICES
 
    So long as the Notes are represented by the Book-Entry Class A Note and the
same is/are held on behalf of the Clearing Agency, notices to Class A
Noteholders may be given by delivery of the relevant notice to the Clearing
Agency for communication by them to entitled account holders in substitution for
delivery to each Class A Noteholder as required by the Class A Conditions.
 
    (D) CANCELLATION
 
    Cancellation of any Class A Note required by the Class A Conditions will be
effected by reduction in the principal amount of the relevant Book-Entry Class A
Note.

of the Master Trust Deed, the Series Notice, the Security Trust Deed, the Note
Trust Deed and the Servicing Agreement as amended (the "Servicing Agreement
Amendment Agreement") dated [*] and made between the Issuer Trustee, Westpac
Banking Corporation ("Westpac") and The Mortgage Company Pty Limited as Servicer
(together with any substitute or successor, the "Servicer") (together with the
Currency Swap Agreements (as defined below), those documents the "Relevant
Documents" and, together with certain other transaction documents defined as
such in the Series Notice, the "Transaction Documents"). Copies of the
Transaction Documents are available for inspection at the principal office of
the Principal Paying Agent, being at the date hereof 60 Victoria Embankment,
London EC4Y 0JP.

    In connection with the issue of the Class B Notes, the Issuer Trustee has
entered into an ISDA master interest rate and currency exchange agreement dated
[*] with Westpac Banking Corporation in such capacity (the "Interest Rate Swap
Provider") together with three confirmations relating thereto dated [*] (the
"Variable Rate Basis Swap" and the "Fixed Rate Basis Swap", respectively and,
together, the "Interest Rate Swaps"). The Issuer Trustee has also entered into
ISDA master interest rate and currency exchange agreements dated [*] with each
of Morgan Guaranty Trust Company of New York, London Branch and Westpac Banking
Corporation (each, in such capacity a "Currency Swap Provider", and together
with the Interest Rate Swap Provider, the "Swap Providers") together with two
confirmations relating to each such agreement dated [*] in respect of two
distinct swap transactions relating to each of the Class B Notes and the Class A
Notes, respectively (each, a "Currency Swap", and together the "Currency
Swaps").
    
 
1. FORM, DENOMINATION AND TITLE
 
    The Class B Notes will be issued in registered form, without interest
coupons, in minimum denominations of US$100,000 and integral multiples thereof.
The Class B Notes will be represented by one or more typewritten fully
registered book-entry notes (each, a "Book-Entry Note" and collectively, the
"Book-Entry Notes") registered in the name of Cede & Co. ("Cede") as nominee of
The Depository Trust Company ("DTC"). Beneficial interests in the Book-Entry
Notes will be shown on, and transfers thereof will be effected only through,
records maintained by DTC and its participants. Morgan Guaranty Trust Company of
New York, Brussels office, as operator of the Euroclear System ("Euroclear") and
Cedel Bank, societe anonyme ("Cedel Bank"), may hold interests in the Book-Entry
Notes on behalf of persons who have accounts with Euroclear and Cedel Bank
through accounts maintained in the names of Euroclear or Cedel Bank, or in the
names of their respective depositories, with DTC.
 
   
    If the Issuer Trustee is obliged to issue Definitive Notes under clause 3.3
of the Note Trust Deed, interests in the applicable Book-Entry Note will be
transferred to the beneficial owners thereof in the form of Definitive Notes,
without interest coupons, in the denominations set forth above. A Definitive
Note will be issued to each Noteholder in respect of its registered holding or
holdings of Class B Notes against delivery by such Noteholders of a written
order containing instructions and such other information as the Issuer Trustee
and Morgan Guaranty Trust Company of New York, London Branch, acting as note
registrar (the "Note Registrar") may require to complete, execute and deliver
such Definitive Notes. In such circumstances, the Issuer Trustee will cause
sufficient Definitive Notes to be executed and delivered to the Note Registrar
for completion, authentication and dispatch to the relevant Noteholders.
    
 
2. STATUS, SECURITY AND RELATIONSHIP BETWEEN THE CLASS B NOTES, THE CLASS A
  NOTES, THE RFSS AND THE RFS CLASS A NOTES
 
    The Class B Notes are secured by a first ranking floating charge over all of
the assets of the Trust (which include, among other things, the Loans (as
defined below) and the Mortgages (as defined below) and related securities) (as
more particularly described in the Security Trust Deed) and rank PARI PASSU and
rateably without any preference or priority among themselves.
 
    The Class B Notes are constituted by the Master Trust Deed and the Series
Notice and are secured by the same security as secures the Class A Notes but the
Class A Notes will rank in priority to the Class B Notes in the event of the
security being enforced and in respect of principal and interest (as set out in
Class B Condition 4 and 5).
 
    The proceeds of the issue of the Class B Notes and the Class A Notes are to
be used by the Issuer Trustee to purchase an equitable interest in certain
housing loans (the "Loans") and certain related mortgages (the "Mortgages") from
Westpac or Westpac Securities Administration Limited in its capacity as trustee
of certain other trusts (each a "WST Seller").
 
                                     III-2
<PAGE>
    In the event that the security for the Class B Notes is enforced and the
proceeds of such enforcement are insufficient, after payment of all other claims
ranking in priority to or PARI PASSU with the Class B Notes under the Security
Trust Deed, to pay in full all principal and interest and other amounts
whatsoever due in respect of the Class B Notes, then the Class B Noteholders
shall have no further claim against the Issuer Trustee in respect of any such
unpaid amounts.
 
    The net proceeds of realisation of the assets of the Trust may be
insufficient to pay all amounts due to the Noteholders. Save in certain limited
circumstances the other assets of the Issuer Trustee will not be available for
payment of any shortfall arising and all claims in respect of such shortfall
shall be extinguished (see further Class B Condition 15). None of the Servicer,
the Trust Manager, the Seller Trustee, Westpac, the Note Trustee or the Security
Trustee has any obligation to any Noteholder for payment of any amount by the
Issuer Trustee in respect of the Notes.
 
    THE ISSUER TRUSTEE MAY FROM TIME TO TIME ISSUE DEBT SECURITIES ("RFSS")
CONSTITUTED UNDER THE MASTER TRUST DEED AND THE SERIES NOTICE TO FUND AMOUNTS
REDRAWN BY RELEVANT BORROWERS UNDER THE LOANS (UP TO THE SCHEDULED AMORTISED
PRINCIPAL OF THE LOANS) FROM TIME TO TIME ("REDRAWS"). RFSS AND CLASS A NOTES
WILL, ON ISSUE, RANK AHEAD OF THE CLASS B NOTES AS TO BOTH PRINCIPAL AND
INTEREST EXCEPT IN THE LIMITED CIRCUMSTANCES SET OUT IN THESE CONDITIONS.
 
    IF, BY THE FIFTH COLLECTION DETERMINATION DATE (AS DEFINED IN CLASS A
CONDITION 5) FOLLOWING THE ISSUE OF AN RFS, THE RFS HAS NOT BEEN REDEEMED, IT
SHALL CONVERT TO AN RFS CLASS A NOTE (EACH, AN "RFS CLASS A NOTE" AND, TOGETHER
THE "RFS CLASS A NOTES"). RFS CLASS A NOTES WILL RANK AHEAD OF CLASS B NOTES AS
TO BOTH PRINCIPAL AND INTEREST EXCEPT IN THE LIMITED CIRCUMSTANCES SET OUT IN
THESE CONDITIONS. RFSS AND RFS CLASS A NOTES ARE REGISTERED, AUSTRALIAN-TRADED
INSTRUMENTS DENOMINATED IN AUSTRALIAN DOLLARS ("A$") AND SOLD TO AUSTRALIAN
INVESTORS ONLY AND FOR THE AVOIDANCE OF DOUBT ARE NOT FUNGIBLE WITH THE CLASS B
NOTES.
 
    THE NOTE TRUST DEED CONTAINS PROVISIONS REQUIRING THE NOTE TRUSTEE TO HAVE
REGARD TO THE INTERESTS OF THE CLASS A NOTEHOLDERS AND THE CLASS B NOTEHOLDERS
AS REGARDS ALL THE POWERS, TRUSTS, AUTHORITIES, DUTIES AND DISCRETIONS OF THE
NOTE TRUSTEE (EXCEPT WHERE EXPRESSLY PROVIDED OTHERWISE), BUT REQUIRING THE NOTE
TRUSTEE IN ANY SUCH CASE TO HAVE REGARD ONLY TO THE INTERESTS OF THE CLASS A
NOTEHOLDERS IF, IN THE NOTE TRUSTEE'S OPINION, THERE IS A CONFLICT BETWEEN THE
INTERESTS OF THE CLASS A NOTEHOLDERS AND THE INTERESTS OF THE CLASS B
NOTEHOLDERS.
 
    THE SECURITY TRUST DEED CONTAINS PROVISIONS REQUIRING THE SECURITY TRUSTEE
TO GIVE PRIORITY TO THE INTERESTS OF THE CLASS A NOTEHOLDERS AND THE HOLDERS OF
RFSS (IF ANY) AND RFS CLASS A NOTES (IF ANY), IF THERE IS A CONFLICT BETWEEN THE
INTERESTS OF SUCH NOTEHOLDERS AND ANY OTHER VOTING MORTGAGEE (AS DEFINED BELOW),
INCLUDING THE CLASS B NOTEHOLDERS.
 
3. COVENANTS OF THE ISSUER TRUSTEE
 
    So long as any of the Class A Notes or the Class B Notes remains
outstanding, the Issuer Trustee has made certain covenants for the benefit of
Class A Noteholders and the Class B Noteholders which are set out in the Master
Trust Deed.
 
    These covenants are as follows:
 
    (a) The Issuer Trustee shall act continuously as trustee of the Trust until
the Trust is terminated as provided by the Master Trust Deed or the Issuer
Trustee has retired or been removed from office in the manner provided under the
Master Trust Deed.
 
    (b) The Issuer Trustee shall:
 
        (i) act honestly and in good faith in the performance of its duties and
    in the exercise of its discretions under the Master Trust Deed;
 
        (ii) subject to the Master Trust Deed, exercise such diligence and
    prudence as a prudent person of business would exercise in performing its
    express functions and in exercising its discretions under
 
                                     III-3
<PAGE>
    the Master Trust Deed, having regard to the interests of the Class A
    Noteholders and the Class B Noteholders and other creditors and
    beneficiaries of the Trust;
 
        (iii) use its best endeavours to carry on and conduct its business in so
    far as it relates to the Master Trust Deed in a proper and efficient manner;
 
        (iv) keep, or ensure that the Trust Manager keeps, accounting records
    which correctly record and explain all amounts paid and received by the
    Issuer Trustee;
 
        (v) keep the Trust separate from each other trust which is constituted
    under the Master Trust Deed and account for assets and liabilities of the
    Trust separately from those of other trusts constituted under the Master
    Trust Deed; and
 
        (vi) do everything and take all such actions which are necessary
    (including obtaining all appropriate authorisations) to ensure that it is
    able to exercise all its powers and remedies and perform all its obligations
    under the Master Trust Deed, the Transaction Documents and all other deeds,
    agreements and other arrangements entered into by the Issuer Trustee under
    the Master Trust Deed.
 
    (c) Except as provided in the Master Trust Deed, the Issuer Trustee shall
not, nor shall it permit any of its officers to, sell, mortgage, charge or
otherwise encumber or part with possession of any asset of the Trust (the "Trust
Assets").
 
    (d) The Issuer Trustee's officers, employees, agents, attorneys, delegates
and sub-delegates shall duly observe and perform the covenants and obligations
of the Master Trust Deed in the same manner as is required of the Issuer
Trustee, and the Issuer Trustee agrees to indemnify the Trust Manager for its
own benefit or for the benefit of the Trust against any loss or damage that the
Trust, the Trust Manager, the Servicer, the Class A Noteholders, the Class B
Noteholders, the Beneficiaries (as defined in the Master Trust Deed) the holders
of RFSs (if any) and the holders of RFS Class A Notes (if any) or other
creditors incur or sustain in connection with, or arising out of, any breach or
default by such officers, employees, agents, delegates and persons in the
observance or performance of any such covenant or obligation, to the extent that
the Issuer Trustee would have been liable if that breach or default had been the
Issuer Trustee's own act or omission.
 
    (e) The Issuer Trustee will open and operate certain bank accounts in
accordance with the Master Trust Deed and the Series Notice.
 
    (f) Subject to the Master Trust Deed and any Transaction Document to which
it is a party, the Issuer Trustee shall act on all directions given to it by the
Trust Manager in accordance with the terms of the Master Trust Deed.
 
    (g) The Issuer Trustee shall properly perform the functions which are
necessary for it to perform under all Transaction Documents in respect of the
Trust.
 
4. INTEREST
 
    (A) PAYMENT DATES
 
    Each Class B Note bears interest on its Invested Amount (as defined below)
from and including 9 June 1998 or such later date as may be agreed between the
Issuer Trustee and the Managers for the issue of the Class B Notes (the "Closing
Date"). Interest in respect of the Class B Notes will be payable quarterly in
arrear on the 19th day falling in July 1998 in respect of the period from (and
including) the Closing Date to (but excluding) that date, and thereafter on each
19 April, 19 July, 19 October and 19 January (each such date a "Payment Date"
and each such three month period beginning on each of 1 April, 1 July, 1 October
and 1 January a "Quarter"). If any Payment Date would otherwise fall on a day
which is not a Business Day (as defined below), it shall be postponed to the
next day which is a Business
 
                                     III-4
<PAGE>
Day (as defined below) unless it would thereby fall into the next calendar month
in which event it shall be brought forward to the immediately preceding Business
Day.
 
    "Business Day" in this Class B Condition 4 and in Class B Conditions 5 and 9
below means any day (London time) other than a Saturday, Sunday or public
holiday on which banks are open for business in Sydney, London and New York
City.
 
    The period beginning on (and including) the Closing Date and ending on (but
excluding) the first Payment Date and each successive period beginning on (and
including) a Payment Date and ending on (but excluding) the next Payment Date is
called an "Interest Period". Interest payable on a Class B Note in respect of
any Interest Period or any other period will be calculated on the basis of the
actual number of days elapsed and a 360 day year.
 
    Interest shall cease to accrue on any Class B Note from (and including):
 
    (i) the date on which the Stated Amount (as defined in Class B Condition
5(a)) of that Class B Note is reduced to zero; or
 
    (ii) if the Stated Amount on the due date for redemption is not zero, the
due date for redemption of the Class B Note, unless, upon due presentation,
payment of principal due is improperly withheld or refused, following which
interest shall continue to accrue on the Invested Amount of the Class B Note at
the rate from time to time applicable to the Class B Notes until the moneys in
respect of that Class B Note have been received by the Note Trustee or the
Principal Paying Agent and notice to that effect is given in accordance with
Class B Condition 12, or the Stated Amount of that Class B Note has been reduced
to zero.
 
    (B) INTEREST RATE
 
    The rate of interest applicable from time to time to the Class B Notes (the
"Interest Rate") will be determined by the Agent Bank on the basis of the
following paragraphs.
 
    On the second London banking day before the beginning of each Interest
Period (each an "Interest Determination Date"), the Agent Bank will determine
the rate "USD-LIBOR-BBA" as an applicable Floating Rate Option under the
Definitions of the International Swaps and Derivatives Association, Inc.
("ISDA") (the "ISDA Definitions") being the rate applicable to any Interest
Period for three-month deposits in US Dollars which appears on the Telerate Page
3750 as of 11am London time, on the Interest Determination Date. If such rate
does not appear on the Telerate Page 3750, the rate for the Interest Period will
be determined as if the Issuer Trustee and Agent Bank had specified
"USD-LIBOR-Reference Banks" as the applicable Floating Rate Option under the
ISDA Definitions. "USD-LIBOR-Reference Banks" means that the rate for an
Interest Period will be determined on the basis of the rates at which deposits
in US Dollars are offered by the Reference Banks (being four major banks in the
London interbank market) at approximately 11.00 am, London time, on the Interest
Determination Date to prime banks in the London interbank market for a period of
three months commencing on the first day of the Interest Period and in a
Representative Amount (as defined in the ISDA Definitions). The Agent Bank will
request the principal London office of each of the Reference Banks to provide a
quotation of its rate. If at least two such quotations are provided, the rate
for that Interest Period will be the arithmetic mean of the quotations. If fewer
than two quotations are provided as requested, the rate for that Interest Period
will be the arithmetic mean of the rates quoted by major banks in New York City,
selected by the Agent Bank, at approximately 11.00 am, New York City time, on
that Interest Determination Date for loans in US Dollars to leading European
banks for a period of three months commencing on the first day of the Interest
Period and in a Representative Amount, provided that on the first day of the
first Interest Period USD-LIBOR-BBA shall be an interpolated rate calculated
with reference to the period from (and including) the Closing Date to (but
excluding) the first Interest Payment Date.
 
                                     III-5
<PAGE>
    The Interest Rate applicable to the Class B Notes for such Interest Period
shall be the aggregate of (i) such Interest Rate or arithmetic mean as
determined by the Agent Bank and (ii) the margin of 0.[*]% applicable to the
Class B Notes.
 
    There is no maximum or minimum Interest Rate.
 
    (C) DETERMINATION OF INTEREST RATE AND CALCULATION OF INTEREST
 
    The Agent Bank will, as soon as practicable after 11.00 am (London time) on
each Interest Determination Date, determine the Interest Rate applicable to, and
calculate the amount of interest payable (the "Interest") for the immediately
succeeding Interest Period. The Interest is calculated by applying the Interest
Rate for the Class B Notes to the Invested Amount (as defined in Class B
Condition 5(a)) of the Class B Note on the first day of the next Interest
Period, multiplying such product by the actual number of days in the relevant
Interest Period and dividing by 360 and rounding the resultant figure down to
the nearest cent (half a cent being rounded upwards). The determination of the
Interest Rate and the Interest by the Agent Bank shall (in the absence of
manifest error) be final and binding upon all parties.
 
    (D) NOTIFICATION AND PUBLICATION OF INTEREST RATE AND INTEREST
 
    The Agent Bank will cause the Interest Rate and the Interest applicable to
each Class B Note for each Interest Period and the relevant Payment Date to be
notified to the Issuer Trustee, the Trust Manager, the Note Trustee, the Paying
Agents, and, for so long as the Class B Notes are listed on the Official List of
the London Stock Exchange Limited (the "London Stock Exchange"), the London
Stock Exchange, and will cause the same to be published in accordance with Class
B Condition 12 on or as soon as possible after the date of commencement of the
relevant Interest Period. The Interest and the relevant Payment Date so
published may subsequently be amended (or appropriate alternative arrangements
made by way of adjustment) without notice in the event of a shortening of the
Interest Period.
 
    (E) DETERMINATION OR CALCULATION BY THE NOTE TRUSTEE
 
    If the Agent Bank at any time for any reason does not determine the Interest
Rate or calculate the Interest for a Class B Note, the Note Trustee shall do so
and each such determination or calculation shall be deemed to have been made by
the Agent Bank. In doing so, the Note Trustee shall apply the foregoing
provisions of this Condition, with any necessary consequential amendments, to
the extent that, in its opinion, it can do so, and, in all other respects it
shall do so in such a manner as it shall deem fair and reasonable in all the
circumstances.
 
    (F) AGENT BANK
 
    The Issuer Trustee will procure that, so long as any of the Class B Notes
remains outstanding, there will at all times be an Agent Bank. The Issuer
Trustee reserves the right at any time to terminate the appointment of the Agent
Bank. Notice of that termination will be given to the Class B Noteholders. If
any person is unable or unwilling to continue to act as the Agent Bank, or if
the appointment of the Agent Bank is terminated, the Issuer Trustee will, with
the approval of the Note Trustee, appoint a successor Agent Bank to act as such
in its place, provided that neither the resignation nor removal of the Agent
Bank shall take effect until a successor approved by the Note Trustee has been
appointed.
 
5. REDEMPTION AND PURCHASE
 
    (A) MANDATORY REDEMPTION IN PART FROM PRINCIPAL COLLECTIONS AND
     APPORTIONMENT OF PRINCIPAL COLLECTIONS BETWEEN THE CLASS A NOTES, THE CLASS
     B NOTES, THE RFS CLASS A NOTES AND THE RFSS
 
    The Class B Notes shall be subject to mandatory redemption in part on any
Payment Date if on that date there are any Principal Collections (as defined
below) available to be distributed in relation to such
 
                                     III-6
<PAGE>
Class B Notes. The principal amount so redeemable in respect of each Class B
Note prior to enforcement of the Security Trust Deed (each a "Principal
Payment") on any Payment Date shall be the amount available for payment as set
out in Class B Condition 5(b) on the day which is four Business Days prior to
the Payment Date (the "Collection Determination Date") preceding that Payment
Date multiplied by the Invested Amount of the applicable Class B Note over the
total Invested Amount of all Class B Notes then outstanding (rounded down to the
nearest cent with half a cent being rounded upwards); provided always that no
Principal Payment on a Class B Note on any date may exceed the amount equal to
the Invested Amount of that Class B Note at that date less amounts charged off
as at that date, or to be charged off on the following Payment Date, as
described in Class B Condition 5(c) (that reduced amount being the "Stated
Amount" of that Class B Note).
 
    The "Invested Amount" of a Class B Note is equal to the Initial Invested
Amount (as defined herein) of such Class B Note less all payments previously
made in respect of principal in respect of such Class B Note. The "Initial
Invested Amount" of a Class B Note is its principal balance at the date of its
issuance.
 
    "Principal Collections" means, in respect of a Collection Period (as defined
below) and as applicable on any Collection Determination Date, the aggregate of:
 
    (i) all amounts received by or on behalf of the Issuer Trustee from or on
behalf of borrowers under the Loans during the Collection Period in respect of
principal, in accordance with the terms of the Loans, including principal
prepayments;
 
    (ii) all other amounts received by or on behalf of the Issuer Trustee under
or in respect of principal under the Loans and the Mortgages during that
Collection Period including:
 
    (A) any amounts recovered in respect of enforcement of Loans and Mortgages
(other than under lender's mortgage insurance), on account of principal;
 
    (B) any payments by Westpac to the Issuer Trustee on the repurchase of a
Loan under the Master Trust Deed during that Collection Period which are
attributable to principal;
 
    (C) any payments by Westpac Securities Administration Limited (in its
capacity as trustee of any other trust established under the Master Trust Deed)
(the "WST Purchaser") on the purchase by the WST Purchaser of any assets of the
Trust which are attributable to principal;
 
    (D) any Prepayment Costs (as defined in the Series Notice) applied towards
Prepayment Benefits (as defined in the Series Notice) under the Series Notice;
and
 
    (E) any Prepayment Benefit Shortfall (as defined in the Series Notice) paid
by Westpac to the Trust under the Series Notice;
 
    (iii) all amounts received by or on behalf of the Issuer Trustee during that
Collection Period from any provider of a Support Facility (as defined in the
Series Notice) (other than the Currency Swap) under that Support Facility and
which the Trust Manager determines should be accounted for to reduce any
principal loss on a Loan, being the total amount outstanding under a Loan after
applying all proceeds from the enforcement of the Loan and related Mortgages (a
"Liquidation Loss") to the extent that Liquidation Loss is attributable to
principal;
 
    (iv) all amounts received by or on behalf of the Issuer Trustee during that
Collection Period:
 
    (A) from Westpac or the WST Seller Trustee (each an "Approved Seller") in
respect of any breach of a representation, warranty or undertaking contained in
the Master Trust Deed or the Series Notice;
 
    (B) from an Approved Seller under any obligation under the Master Trust Deed
or the Series Notice to indemnify or reimburse the Issuer Trustee for any
amount;
 
    (C) from the Servicer, in respect of any breach of any representation,
warranty or undertaking contained in the Servicing Agreement; and
 
                                     III-7
<PAGE>
    (D) from the Servicer under any obligation under the Servicing Agreement to
indemnify or reimburse the Issuer Trustee for any amount,
 
    in each case, which are determined by the Trust Manager to be in respect of
principal payable under the Loans and the Mortgages;
 
    (v) any amounts in the nature of principal received by or on behalf of the
Issuer Trustee during that Collection Period pursuant to the sale of any asset
comprised in the Trust (including any amount received by the Issuer Trustee on
the issue of Notes and which was not used to purchase Loans or Mortgages, and
which the Trust Manager determines is surplus to the requirements of the Trust);
 
    (vi) (for the purposes of clause 6.11 of the Series Notice only) any amount
of Excess Available Income (as defined in the Series Notice) to be applied to
pay a Principal Charge Off or a Carryover Charge Off (as defined in the Series
Notice);
 
    (vii) any amount received by or on behalf of the Issuer Trustee during that
Collection Period as proceeds from the issue of any RFS to the extent not
applied to reimburse amounts drawn under the Redraw Facility dated [*] between
the Issuer Trustee, the Trust Manager and Westpac (the "Redraw Facility");
 
    (viii) any Excess Available Income to be applied to Principal Draws (as
defined in the Series Notice) made on a previous Payment Date;
 
    (ix) any Prepayment Calculation Adjustment (as defined in the Series Notice)
for that Collection Period;
 
    (x) any Substitution Net Transfer Amount (Principal) (as defined in the
Series Notice) received by the Trust from a WST Purchaser with respect to that
Collection Period;
 
less any amounts deducted by or paid to Westpac to reimburse Redraws funded by
Westpac for which Westpac has not previously been reimbursed. A premium
receivable by the Issuer Trustee on the entry into a replacement Currency Swap
under clause 6.26 of the Series Notice is not treated as a Principal Collection.
 
    "Collection Period" means, in relation to a Payment Date, the period from
(and including) the tenth day of the Quarter preceding the Quarter in which the
Payment Date occurs to (and including) the ninth day of the Quarter in which the
Payment Date occurs. The first Collection Period is the period from (but
excluding) May 6, 1998 (the "Cut-Off Date") to (and including) July 9. The last
Collection Period is the period from (but excluding) the last day of the
previous Collection Period to (and including) the termination date of the Trust.
 
    (B) INITIAL PRINCIPAL DISTRIBUTIONS PRINCIPAL COLLECTIONS WILL BE
     DISTRIBUTED AS FOLLOWS ON EACH PAYMENT DATE BEFORE ANY PAYMENTS IN RESPECT
     OF THE NOTES:
 
    (i) first, to repay any Redraws provided by Westpac in relation to Loans to
the extent that Westpac has not previously been reimbursed in relation to those
Redraws;
 
    (ii) second, to repay all principal outstanding under the Redraw Facility on
that Payment Date;
 
    (iii) third, to allocate to Total Available Funds any Principal Draw (as
defined in the Series Notice); and
 
    (iv) fourth, to repay PARI PASSU and rateably all amounts outstanding under
the RFSs (if any).
 
    (C) PRINCIPAL ALLOCATION METHOD
 
    On each Collection Determination Date, the Trust Manager will determine the
A$ Equivalent of the aggregate of the Class B Stated Amounts divided by the sum
of (i) the A$ Equivalent of the Total Stated
 
                                     III-8
<PAGE>
Amount at that time, plus (ii) the Redraw Limit at that time, plus (iii) the
aggregate of the RFS Stated Amount at that time, plus (iv) the aggregate of the
RFS Class A Stated Amounts at that time (the "Subordinated Percentage"). The
Trust Manager will calculate the Subordinated Percentage so as to determine the
appropriate principal distribution methodology to apply for that Collection
Period, as described below.
 
    (D) APPLICABILITY OF SERIAL METHOD 1
 
    If, on any Collection Determination Date:
 
    (i) the Subordinated Percentage at the previous Collection Determination
Date was greater than or equal to twice the Initial Subordinated Percentage;
 
    (ii) that Collection Determination Date occurs on or before the third
anniversary of the Closing Date;
 
    (iii) the Total Invested Amount as at that Collection Determination Date as
a percentage of the Total Initial Invested Amount, is greater than or equal to
10%;
 
    (iv) the Average Quarterly Percentage as at that Collection Determination
Date:
 
    (A) does not exceed 2% and the Total Carryover Charge Off on that Collection
Determination Date does not exceed 30% of the Class B Initial Invested Amount;
or
 
    (B) does not exceed 4% and the Total Carryover Charge Off on such Collection
Determination Date does not exceed 10% of the Class B Initial Invested Amount;
and
 
    (v) the Stated Amounts of all Class B Notes as at that Collection
Determination Date exceeds 0.25% of the aggregate of all Initial Invested
Amounts of all Class A Notes and all Class B Notes as at the Collection
Determination Date;
 
then Principal Collections will be allocated serially in accordance with Serial
Method I set out in paragraph (e) below.
 
    (E) SERIAL METHOD 1
 
    On any Collection Determination Date, if the Trust Manager determines that
Serial Method 1 should apply, the Issuer Trustee (based on instructions from the
Trust Manager) will pay out of Principal Collections for the relevant Collection
Period which remain after the Initial Principal Distributions, on the Payment
Date following that Collection Determination Date the following amounts in the
following priority:
 
    (i) first PARI PASSU and rateably between themselves:
 
    (A) as a payment, denominated in A$, to the Currency Swap Providers under
the relevant swap confirmations relating to the Class A Notes of an amount equal

    (ii) that Collection Determination Date occurs after the third anniversary
of the Closing Date;
 
    (iii) the Total Invested Amount as at that Collection Determination Date, as
a percentage of the Total Initial Invested Amount, is greater than or equal to

Manager) will pay out of Principal Collections for the relevant Collection
Period which remain after the Initial Principal Distributions the following

Notice) calculated on the Collection Determination Date for that Collection
Period, the Trust Manager must, on and with effect from the Payment Date
immediately following the end of the Collection Period:
 
    (i) reduce PARI PASSU the Class B Stated Amount of each of the Class B Notes
by the US$ Equivalent of the amount of that excess which is attributable to each
Class B Note until the Class B Stated Amount is zero; and
 
                                     III-12
<PAGE>
    (ii) if the Class B Stated Amount is zero and any amount of that excess has
not been applied under paragraph (i), reduce PARI PASSU and rateably as between
themselves (based on the Stated Amount of the RFSs (if any), the Principal
Outstanding under the Redraw Facility, the Stated Amount of the RFS Class A
Notes (if any) and the A$ Equivalent of the Stated Amount of the Class A Notes):
 
    (A) the Class A Stated Amount on each of the Class A Notes by the US$
Equivalent of the balance of that excess which is attributable to each Class A
Note until the Class A Stated Amount of that Class A Note is zero;

that excess until the Principal Outstanding is zero.
 
    (M) CALCULATION OF PRINCIPAL PAYMENTS, STATED AMOUNT AND BOND FACTOR
 
    (i) On each Collection Determination Date, the Trust Manager shall
determine:
 
    (A) the amount of any Principal Payment in respect of each Class B Note on
the Payment Date following that Collection Determination Date;
 
    (B) the Stated Amount and Invested Amount of each Class B Note as of the
first day of the next following Interest Period (after deducting any Principal
Payment due to be made in respect of each Class B Note on the next Payment Date)
and
 
    (C) the fraction in respect of each Class B Note expressed as a decimal to
the seventh point (the "Bond Factor" of which the numerator is the aggregate of
the Invested Amount of all Class B Notes at that date less all Principal
Payments to be made on the following Payment Date, and the denominator is the
Initial Invested Amount of the Class B Notes.
 
    (ii) The Trust Manager will notify the Note Trustee, the Principal Paying
Agent, the Agent Bank and (for so long as the Class B Notes are listed on the
London Stock Exchange) the London Stock Exchange by not later than the
Collection Determination Date immediately preceding the relevant Payment Date of
each determination of a Principal Payment, Invested Amount, Stated Amount and
Bond Factor and will immediately cause details of each of those determinations
to be published in accordance with Condition 12. If no Principal Payment is due
to be made on the Class B Notes on any Payment Date a notice to this effect will
be given to the Class B Noteholders in accordance with Class B Condition 12.
 
    (iii) If the Trust Manager does not at any time for any reason determine a
Principal Payment, the Invested Amount, the Stated Amount or the Bond Factor
applicable to Class B Notes in accordance with this paragraph, the Principal
Payment, Invested Amount, the Stated Amount and the Bond Factor shall be
determined by the Note Trustee in accordance with this paragraph and paragraph
(i) above (but based on the information in its possession) and each such
determination or calculation shall be deemed to have been made by the Trust
Manager.
 
    (iv) The Trust Manager will deliver to the Principal Paying Agent a
quarterly servicing report as set forth in clause 11 of the Note Trust Deed.
 
    (N) REDEMPTION FOR TAXATION OR OTHER REASONS

                                     III-13
<PAGE>
deduct or withhold from any payment of principal or interest in respect of the
Class B Notes any amount for or on account of any present or future taxes,
duties, assessments or governmental charges of whatever nature imposed, levied,
collected, withheld or assessed by the Commonwealth of Australia or any of its
political sub-divisions or any of its authorities or (ii) the total amount
payable in respect of interest in relation to the Loans for a Collection Period
ceases to be receivable (whether or not actually received) by the Issuer Trustee
during such Collection Period by reason of any present or future taxes, duties,
assessments or governmental charges of whatever nature imposed, levied,
collected, withheld or assessed by the Commonwealth of Australia or any of its
political sub-divisions or any of its authorities, the Issuer Trustee must, when
so directed by the Trust Manager (at any time at the Trust Manager's option)
(provided that the Issuer Trustee will be in a position on such Payment Date to
discharge (and will so certify to the Issuer Trustee and the Note Trustee) all
its liabilities in respect of the Class B Notes and any amounts required under
the Security Trust Deed to be paid in priority to or PARI PASSU with the Class B
Notes), upon having given not more than 60 nor less than 30 days' notice to the
Class B Noteholders in accordance with Class B Condition 12 redeem all, but not
some only, of the Class B Notes at their Invested Amount (or at the option of
the holders of 75% of the aggregate Invested Amount of Class B Notes at the
time, at their Stated Amount), together with accrued interest to the date of
redemption on any subsequent Payment Date, provided that the holders of 75% of
the aggregate Invested Amount of Class B Notes at the time may elect, and shall
notify the Issuer Trustee and the Trust Manager, that they do not require the
Issuer Trustee to redeem the Class B Notes in the circumstances described above.
 
    (O) OPTIONAL REDEMPTION IN WHOLE
 
    On any Payment Date, and upon giving no more than 60 nor less than 30 days'
notice to the Note Trustee and the Security Trustee, on which the aggregate

outstanding of the Loans at the Cut-Off Date, the Issuer Trustee may redeem all
(but not some only) of the Class B Notes at their Stated Amount.
 
    (P) REDEMPTION ON MATURITY
 
    If not otherwise redeemed, the Class B Notes will be redeemed at their

Note Trustee may rely upon an officer's certificate under the Note Trust Deed
from the Trust Manager on behalf of the Issuer Trustee certifying or stating the
opinion of each person signing such certificate as:
 
    (i) to the fair value (within 90 days of such release) of the property or
securities proposed to be released from the Security Trust Deed;
 
    (ii) that in the opinion of such person the proposed release will not impair
the security under the Security Trust Deed in contravention of the provisions of
the Security Trust Deed or the Note Trust Deed;
 
    (iii) that the Issuer Trustee will be in a position to discharge all its
liabilities in respect of the relevant Class B Notes; and
 
    (iv) any amounts required under the Security Trust Deed to be paid in
priority to or PARI PASSU with those Class B Notes,
 
                                     III-14
<PAGE>
    and such officer's certificate shall be conclusive and binding on the
Trustee and the holders of those Class B Notes.
 
    (S) PURCHASES
 
    The Issuer Trustee may not purchase any Class B Notes at any time.
 
6. PAYMENTS
 
    (A) METHOD OF PAYMENT
 
    Any instalment of interest or principal, payable on any Class B Note which
is punctually paid or duly provided for by the Issuer Trustee to the Principal
Paying Agent on the applicable Payment Date or Maturity Date shall be paid to
the person in whose name such Class B Note is registered on the Record Date, by
cheque mailed first-class, postage prepaid, to such person's address as it
appears on the Note Register on such Record Date, except that, unless Definitive
Notes have been issued pursuant to clause 3.3 of the Note Trust Deed, with
respect to Class B Notes registered on the Record Date in the name of the
nominee of DTC (initially, such nominee to be Cede & Co.), payment will be made
by wire transfer in immediately available funds to the account designated by
such nominee and except for the final instalment of principal payable with
respect to such Class B Note on a Payment Date or Maturity Date.
 
    (B) INITIAL PRINCIPAL PAYING AGENT
 
    The initial Principal Paying Agent is Morgan Guaranty Trust Company of New
York, London Branch, at its office at 60 Victoria Embankment, London EC4Y 0JP.
 
    (C) PAYING AGENTS
 
    The Issuer Trustee (or the Trust Manager on its behalf after advising the
Issuer Trustee thereof) may at any time (with the previous written approval of
the Note Trustee) vary or terminate the appointment of any Paying Agent and
appoint additional or other Paying Agents, provided that it will at all times
maintain a Paying Agent having a specified office in London and in New York
City. Notice of any such termination or appointment and of any change in the
office through which any Paying Agent will act will be given in accordance with
Class B Condition 12.
 
    (D) DUE DATE FOR REDEMPTION
 
    If the due date for redemption in full of a Class B Note is not a Payment
Date, the interest accrued in respect of the period from the preceding Payment
Date (or from the Closing Date as the case may be) shall be payable only against
presentation or surrender of the relevant Class B Note.
 
    (E) PAYMENTS ON BUSINESS DAYS
 
    If the due date for payment of any amount of principal or Interest in
respect of any Class B Note is not a Business Day then payment will not be made
until the next succeeding Business Day and the holder thereof shall not be
entitled to any further interest or other payment in respect of that delay. In
this Condition 6 the expression "Business Day" means any day (other than a
Saturday, Sunday or a public holiday) on which banks are open for business in
the place where the specified office of the Paying Agent is situated and, in the
case of payment by transfer to a US dollar account, in New York City and prior
to any exchange of the Book-Entry Note (in respect of the Class B Notes) for any
definitive Class B Notes, on which DTC is open for business.
 
                                     III-15
<PAGE>
    (F) Interest
 
    If Interest is not paid in respect of a Class B Note on the date when due
and payable (other than because the due date is not a Business Day), that unpaid
Interest shall itself bear interest at the Interest Rate applicable from time to
time to the Class B Notes until the unpaid interest, and interest on it, is
available for payment and notice of that availability has been duly given in
accordance with Class B Condition 12.
 
7. TAXATION
 
    All payments in respect of the Class B Notes will be made without
withholding or deduction for, or on account of, any present or future taxes,
duties or charges of whatsoever nature unless the Issuer Trustee or any Paying
Agent is required by applicable law to make any such payment in respect of the
Class B Notes subject to any withholding or deduction for, or on account of, any
present or future taxes, duties or charges of whatsoever nature. In that event
the Issuer Trustee or that Paying Agent (as the case may be) shall make such
payment after such withholding or deduction has been made and shall account to
the relevant authorities for the amount so required to be withheld or deducted.
Neither the Issuer Trustee nor any Paying Agent will be obliged to make any
additional payments to Class B Noteholders in respect of that withholding or
deduction.
 
8. PRESCRIPTION
 
    A Class B Note shall become void in its entirety unless surrendered for
payment within ten years of the Relevant Date in respect of any payment thereon
the effect of which would be to reduce the Stated Amount of that Class B Note to
zero. After the date on which a Class B Note becomes void in its entirety, no
claim may be made in respect of it.
 
    As used in these Conditions, the "Relevant Date" means the date on which a
payment first becomes due but, if the full amount of the money payable has not
been received by the Principal Paying Agent or the Note Trustee on or prior to
that date, it means the date on which, the full amount of such money having been
so received, notice to that effect is duly given in accordance with Class B
Condition 12.

(that opinion, being subject to the approval of the Note Trustee in accordance
with the provisions of the Security Trust Deed) is not remedied within 30 days
(or such longer period as may be specified in the notice, that longer period
having been approved by the Note Trustee, for so long as amounts outstanding
under the Offered Notes are 75% of the Secured Moneys) after written notice from

10. ENFORCEMENT
 
    (a) At any time after an Event of Default occurs, the Security Trustee may,
with the prior written consent of the Note Trustee in accordance with the
provisions of the Security Trust Deed and shall, if so directed by (a) the Note
Trustee alone, where the Note Trustee is the only Voting Mortgagee, or otherwise
(b) an Extraordinary Resolution (being 75% of votes capable of being cast by
Voting Mortgagees present or in person or by proxy of the relevant meeting or a
written resolution signed by all Voting Mortgagees) of the Voting Mortgagees
(which includes the Note Trustee on behalf of Noteholders, but not the
Noteholders themselves), declare the Class B Notes immediately due and payable
and enforce the Security Trust Deed. If an Extraordinary Resolution of Voting
Mortgagees referred to in sub-paragraph (b) above elects not to direct the
Security Trustee to enforce the Security Trust Deed, in circumstances where the
Security Trustee could enforce, the Note Trustee may nonetheless, and shall at
the direction of the Class B Noteholders, direct the Security Trustee to enforce
the Security Trust Deed on behalf of the Noteholders.
 
    "Voting Mortgagee" means:
 
    (a) for so long as the amounts outstanding under the Class A Notes and the
Class B Notes are 75% or more of all amounts secured by the Security Trust Deed,
the Note Trustee alone; and
 
    (b) at any other time:
 
    (i) the Note Trustee, acting on behalf of the Noteholders under the Note
Trust Deed and the Security Trust Deed: and
 
    (ii) each other Mortgagee under the Security Trust Deed (other than the
Noteholders).
 
    Subject to being indemnified in accordance with the Security Trust Deed, the
Security Trustee shall take all action necessary to give effect to any direction
by the Note Trustee where it is the only Voting Mortgagee or to any
Extraordinary Resolution of the Voting Mortgagees and shall comply with all
directions given by the Note Trustee where it is the only Voting Mortgagee or
contained in or given pursuant to any Extraordinary Resolution of the Voting
Mortgagees in accordance with the Security Trust Deed.
 
    No Noteholder is entitled to enforce the Security Trust Deed or to appoint
or cause to be appointed a receiver to any of the assets secured by the Security
Trust Deed or otherwise to exercise any power conferred by the terms of any
applicable law on chargees except as provided in the Security Trust Deed.
 
    (b) If any of the Class B Notes remains outstanding and are due and payable
otherwise than by reason of a default in payment of any amount due on the Class
B Notes, the Note Trustee must not vote under the Security Trust Deed to, or
otherwise direct the Security Trustee to, dispose of the Mortgaged Property
unless either:
 
    (i) a sufficient amount would be realised to discharge in full all amounts
owing to the Class B Noteholders and any other amounts payable by the Issuer
Trustee ranking in priority to or PARI PASSU with the Class B Notes; or
 
    (ii) the Note Trustee is of the opinion, reached after considering at any
time and from time to time the advice of a merchant bank or other financial
adviser selected by the Note Trustee, that the cash flow receivable by the
Issuer Trustee (or the Security Trustee under the Security Trust Deed) will not
(or that there is a significant risk that it will not) be sufficient, having
regard to any other relevant actual, contingent or prospective liabilities of
the Issuer Trustee, to discharge in full in due course all the amounts referred
to in paragraph (i).
 
    (c) Neither the Note Trustee nor the Security Trustee will be liable for any
decline in the value, nor any loss realised upon any sale or other dispositions
made under the Security Trust Deed, of any Mortgaged Property or any other
property which is charged to the Security Trustee by any other person in respect
of or relating to the obligations of the Issuer Trustee or any third party in
respect of the Issuer
 
                                     III-18
<PAGE>
Trustee or the Class B Notes or relating in any way to the Mortgaged Property.
Without limitation, neither the Note Trustee nor the Security Trustee shall be
liable for any such decline or loss directly or indirectly arising from its
acting, or failing to act, as a consequence of an opinion reached by it.
 
    (d) The Note Trustee shall not be bound to vote under the Security Trust
Deed, or otherwise direct the Security Trustee under the Security Trust Deed or
to take any proceedings, actions or steps under, or any other proceedings
pursuant to or in connection with the Security Trust Deed, the Note Trust Deed,
any Class B Notes, unless directed or requested to do so by Noteholders holding
at least 75% of the aggregate Invested Amount of Class A Notes or Class B Notes
(as the case may be) at the time and then only if the Note Trustee is
indemnified to its satisfaction against all action, proceedings, claims and
demands to which it may render itself liable and all costs, charges, damages and
expenses which it may incur by so doing.
 
    (e) So long as any of the Class A Notes remains outstanding, the Note
Trustee shall not, and shall not be bound to, act at the request or direction of
the Class B Noteholders under paragraph (d) unless (i) so to do would not in its
opinion be materially prejudicial to the interests of the Class A Noteholders;
(ii) the relevant action is sanctioned by way of written approval of Class A
Noteholders holding at least 75% of the aggregate Invested Amount of Class A
Notes at the time; or (iii) in the case of giving notice pursuant to Condition
10 of the Class B Conditions, the Class A Notes are all then repayable in full.
 
    (f) Only the Security Trustee may enforce the provisions of the Security
Trust Deed and neither the Note Trustee nor any holder of a Class B Note is
entitled to proceed directly against the Issuer Trustee to enforce the
performance of any of the provisions of the Security Trust Deed, the Class B
Notes (including these Class B Conditions).
 
    (g) The rights, remedies and discretions of the Class B Noteholders under
the Security Trust Deed including all rights to vote or give instructions or
consent can only be exercised by the Note Trustee on behalf of the Class B
Noteholders in accordance with the Security Trust Deed. The Security Trustee may
rely on any instructions or directions given to it by the Note Trustee as being
given on behalf of the Class B Noteholders from time to time and need not
enquire whether the Note Trustee or the Noteholders from time to time have
complied with any requirements under the Note Trust Deed or as to the
reasonableness or otherwise of the Note Trustee. The Security Trustee is not
obliged to take any action, give any consent or waiver or make any determination
under the Security Trust Deed without being directed to do so by the Note
Trustee or the Voting Mortgagees in accordance with the Security Trust Deed.
 
    UPON ENFORCEMENT OF THE SECURITY CREATED BY THE SECURITY TRUST DEED, THE NET
PROCEEDS THEREOF MAY BE INSUFFICIENT TO PAY ALL AMOUNTS DUE ON REDEMPTION TO THE
NOTEHOLDERS. THE PROCEEDS FROM ENFORCEMENT (WHICH WILL NOT INCLUDE AMOUNTS
REQUIRED BY LAW TO BE PAID TO THE HOLDER OF ANY PRIOR RANKING SECURITY INTEREST,
THE PROCEEDS OF OR AMOUNTS CREDITED TO THE COLLATERAL ACCOUNT UNDER THE
LIQUIDITY FACILITY AGREEMENT (AS DEFINED IN THE MASTER TRUST DEED) AND PAYABLE
TO THE LIQUIDITY FACILITY PROVIDER (AS DEFINED IN THE MASTER TRUST DEED) AND THE
PROCEEDS OF CASH COLLATERAL LODGED WITH AND PAYABLE TO A SWAP PROVIDER OR OTHER
PROVIDER OF A SUPPORT FACILITY (AS DEFINED IN THE MASTER TRUST DEED)) WILL BE
APPLIED IN THE ORDER OF PRIORITY AS SET OUT IN THE SECURITY TRUST DEED. ANY
CLAIMS OF NOTEHOLDERS REMAINING AFTER REALISATION OF THE SECURITY AND
APPLICATION OF THE PROCEEDS AS AFORESAID SHALL, EXCEPT IN CERTAIN LIMITED
CIRCUMSTANCES, BE EXTINGUISHED.
 
11. REPLACEMENTS OF CLASS B NOTES
 
    If any Class B Note is lost, stolen, mutilated, defaced or destroyed, it may
be replaced at the specified office of the Principal Paying Agent upon payment
by the claimant of the expenses incurred in connection with that replacement and
on such terms as to evidence and indemnity as the Issuer Trustee may reasonably
require. Mutilated or defaced Class B Notes must be surrendered before
replacements will be issued.
 
                                     III-19
<PAGE>
12. NOTICES
 
    All notices, other than notices given in accordance with the following
paragraph, to Class B Noteholders shall be deemed given if in writing and
mailed, first-class, postage prepaid to each Class B Noteholder, at his or her
address as it appears on the Note Register, not later than the latest date, and
not earlier than the earliest date, prescribed for the giving of such notice. In
any case where notice to Class B Noteholders is given by mail, neither the
failure to mail such notice nor any defect in any notice so mailed to any
particular Class B Noteholder shall affect the sufficiency of such notice with
respect to other Class B Noteholders, and any notice that is mailed in the
manner herein provided shall conclusively be presumed to have been duly given.
 
    A notice may be waived in writing by the relevant Class B Noteholder, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Class B Noteholders shall be filed with the Note
Trustee but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such a waiver.
 
    Any such notice shall be deemed to have been given on the date such notice
is deposited in the mail.
 
    In case, by reason of the suspension of regular mail services as a result of
a strike, work stoppage or similar activity, it shall be impractical to mail
notice of any event to Class B Noteholders when such notice is required to be
given, then any manner of giving such notice as the Trustee shall direct the
Note Trustee shall be deemed to be a sufficient giving of such notice.
 
    Any notice specifying a Payment Date, an Interest Rate, Interest payable, a
Principal Payment (or the absence of a Principal Payment), an Invested Amount, a
Stated Amount or a Bond Factor shall be deemed to have been duly given if the
information contained in such notice appears on the relevant page of the Reuters
Screen or such other similar electronic reporting service as may be approved by
the Note Trustee and notified to Class B Noteholders (the "Relevant Screen").
Any such notice shall be deemed to have been given on the first date on which
such information appeared on the Relevant Screen. If it is impossible or
impracticable to give notice in accordance with this paragraph then notice of
the matters referred to in this Condition shall be given in accordance with the
preceding paragraph.
 
    The Principal Paying Agent shall deliver a quarterly servicing report for
each Collection Period to each Class B Noteholder on the Notice Date relating to
such Collection Period in the method provided in the first paragraph of this
Condition 12.
 
13. MEETINGS OF VOTING MORTGAGEES AND VOTES OF CLASS B NOTEHOLDERS;
  MODIFICATIONS; CONSENTS; WAIVER
 
    The Security Trust Deed contains provisions for convening meetings of the
Voting Mortgagees to, INTER ALIA, enable the Voting Mortgagees to direct or
consent to the Security Trustee taking or not taking certain actions under the
Security Trust Deed, for example to enable the Voting Mortgagees to direct the
Security Trustee to enforce the Security Trust Deed.
 
    For so long as the amounts outstanding under the Notes are 75% or more of
all amounts secured by the Security Trust Deed, the Note Trustee may direct the
Security Trustee to do any act or thing which the Security Trustee is required
to do, or may only do, at the direction of an Extraordinary Resolution of the
Voting Mortgagees.
 
    Neither the Security Trustee nor the Trust Manager may call a meeting of
Voting Mortgagees without the Note Trustee's consent, if the amounts outstanding
under the Notes are 75% or more of all amounts secured by the Security Trust
Deed.
 
    The Note Trust Deed contains provisions for the Class A Noteholders to
consider any matter affecting their interests. In general, the holders of a
majority of the aggregate Invested Amount of the Class A Notes may take or
consent to any action permitted to be taken by Class A Noteholders under the
Note Trust Deed. Notwithstanding the foregoing, the consent of holders of 75% of
the aggregate Invested Amount of
 
                                     III-20
<PAGE>
the Class A Notes shall be required to (i) direct the Note Trustee to direct the
Security Trustee to enforce the security under the Note Trust Deed, (ii)
override any waiver by the Note Trustee of a breach of any provisions of the
Transaction Documents or an Event of Default, (iii) alter, add, or modify the
terms and conditions of the Class A Notes or the provisions of any of the
Transaction Documents if such alteration, addition or modification is, in the
opinion of the Note Trustee, materially prejudicial or likely to be materially
prejudicial to the Offered Noteholders as a whole or the Class A Noteholders,
which shall include any modification to the date of maturity of the Class A
Notes or a modification which would have the effect of postponing any day for
payment of interest in respect of any Class A Notes, reducing or cancelling the
amount of principal payable in respect of any Class A Notes or the rate of
interest applicable to any Class A Notes or altering the percentage of the
aggregate Invested Amount required to consent to any action or altering the
currency of payment of any Class A Notes or an alteration of the date or
priority of redemption of the Class A Notes (any such modification being
referred to below as a "Basic Terms Modification"). The Note Trust Deed contains
provisions limiting the powers of the Class B Noteholders, INTER ALIA, to
request or direct the Note Trustee to take any action that would be materially
prejudicial to the interests of the Class A Noteholders. Except in certain
circumstances, the Note Trust Deed imposes no such limitations on the powers of
the Class A Noteholders, the exercise of which will be binding on the Class B
Noteholders, irrespective of the effect on the Class B Noteholders' interests.
Any action taken by the requisite percentage of the Invested Amount of the Class
A Noteholders shall be binding on all Class A Noteholders (both present and
future).
 
    Pursuant to the terms of the Note Trust Deed, the Note Trustee may agree,
without the consent of the Class B Noteholders, among other things, (i) to any
modification (except a Basic Terms Modification) of, or to the waiver or
authorisation of any breach or proposed breach of the Class B Notes (including
these Conditions), or any of the Transaction Documents which is not, in the
opinion of the Note Trustee materially prejudicial to the interests of the Class
B Noteholders or (ii) to any modification of the Class B Notes (including these
Conditions, or any of the Transaction Documents which, in the Note Trustee's
opinion, is to correct a manifest error or is of a formal, minor or technical
nature. The Note Trustee may also, without the consent of the Class B
Noteholders, determine that any Event of Default or any condition, event or act
which with the giving of notice and/or lapse of time and/or the issue of a
certificate would constitute an Event of Default shall not, or shall not subject
to specified conditions, be treated as such. Any such modification, waiver,
authorisation or determination shall be binding on the Class B Noteholders and,
unless the Note Trustee agrees otherwise, any such modification shall be
notified to the Class B Noteholders in accordance with Class B Condition 12 as
soon as practicable thereafter.
 
14. INDEMNIFICATION AND EXONERATION OF THE NOTE TRUSTEE AND THE SECURITY TRUSTEE
 
    The Note Trust Deed contains provisions for the indemnification of the Note
Trustee and for its relief from responsibility, including provisions relieving
it from taking proceedings to realise the security and to obtain repayment of
the Class B Notes unless indemnified to its satisfaction. Each of the Note
Trustee and the Security Trustee is entitled to enter into business transactions
with the Issuer Trustee and/or any other party to the Relevant Documents without
accounting for any profit resulting from such transactions. Neither the Security
Trustee nor the Note Trustee will be responsible for any loss, expense or
liability which may be suffered as a result of any assets secured by the
Security Trust Deed, Mortgaged Property or any deeds or documents of title
thereto, being uninsured or inadequately insured or being held by or to the
order of the Servicer or any of its affiliates or by clearing organisations or
their operators or by any person on behalf of the Note Trustee.
 
15. LIMITATION OF LIABILITY OF THE ISSUER TRUSTEE
 
    (A) GENERAL
 
    Clause 33 of the Master Trust Deed applies to the obligations and
liabilities of the Issuer Trustee in relation to this Class B Note.
 
                                     III-21
<PAGE>
    (B) LIABILITY OF TRUSTEE LIMITED TO ITS RIGHT OF INDEMNITY
 
    (i) This Class B Note applies to the Issuer Trustee only in its capacity as
trustee of the Trust and in no other capacity. A liability arising under or in
connection with this Class B Note or the Trust can be enforced against the
Issuer Trustee only to the extent to which it can be satisfied out of property
of the Trust out of which the Issuer Trustee is actually indemnified for the
liability. This limitation of the Issuer Trustee's liability applies despite any
other provision of this Class B Note or any other Transaction Document and
extends to all liabilities and obligations of the Issuer Trustee in any way
connected with any representation, warranty, conduct, omission, agreement or
transaction related to this Class B Note or the Trust.
 
    (ii) None of the Note Trustee or the Class B Noteholders may take action
against the Issuer Trustee in any capacity other than as trustee of the Trust or
seek the appointment of a receiver (except under the Security Trust Deed), or a
liquidator, an administrator or any similar person to the Issuer Trustee or
prove in any liquidation, administration or arrangements of or affecting the
Issuer Trustee.
 
    (iii) The provisions of this Condition 15 shall not apply to any obligation
or liability of the Issuer Trustee to the extent that it is not satisfied
because under a Transaction Document or by operation of law there is a reduction
in the extent of the Issuer Trustee's indemnification out of the Trust Assets as
a result of the Issuer Trustee's fraud, negligence or breach of trust.
 
    (iv) It is acknowledged that the Trust Manager, the Servicer, each Paying
Agent, the Agent Bank and the Note Trustee (each a "Relevant Party") are
responsible under the Transaction Documents for performing a variety of
obligations relating to the Trust. No act or omission of the Issuer Trustee
(including any related failure to satisfy its obligations under this Class B
Note or a Transaction Document) will be considered fraud, negligence or breach
of trust of the Issuer Trustee for the purpose of sub-paragraph (iii) of this
Condition 15 to the extent to which the act or omission was caused or
contributed to by any failure by any Relevant Party or any other person who
provides services in respect of the Trust (other than a person who has been
delegated or appointed by the Issuer Trustee and for whom the Issuer Trustee is
responsible under the Transaction Documents, other than a Relevant Party) to
fulfil its obligations relating to the Trust or by any other act or omission of
a Relevant Party or any other person who provides services in respect of the
Trust (other than a person who has been delegated or appointed by the Issuer
Trustee and for whom the Issuer Trustee is responsible under the Transaction
Documents, other than a Relevant Party).
 
    (v) No attorney, agent, receiver or receiver and manager appointed in
accordance with a Transaction Document (including without limitation a Relevant
Party) has authority to act on behalf of the Issuer Trustee in a way which
exposes the Issuer Trustee to any personal liability and no act or omission of
any such person will be considered fraud, negligence or breach of trust of the
Issuer Trustee for the purpose of sub-paragraph (iii), if the Issuer Trustee has
exercised reasonable care in the selection and supervision of such a person.
 
16. GOVERNING LAW
 
    The Class B Notes and the Relevant Documents (other than the Security Trust
Deed which is governed by the laws of the Australian Capital territory and the
Currency Swap with Morgan Guaranty Trust Company of New York, London Office,
which is governed by the laws of England) are governed by, and shall be
construed in accordance with, the laws of New South Wales, Australia.
 
   
SUMMARY OF PROVISIONS RELATING TO THE CLASS B NOTES WHILE IN BOOK-ENTRY FORM
    
 
   
    The Class B Notes will initially be represented by typewritten book-entry
notes (the "Book-Entry Class B Notes"), without coupons, in the principal amount
of US$32,300,000. The Book-Entry Class B Notes will be deposited with the Common
Depositary for DTC on or about the Closing Date. Upon
    
 
                                     III-22
<PAGE>
   
deposit of the Book-Entry Class B Notes with the Common Depositary, DTC will
credit each investor in the Class B Notes with a principal amount of Class B
Notes for which it has subscribed and paid.
    
 
   
    The Book-Entry Class B Notes will be exchangeable for definitive Class B
Notes in certain circumstances described below.
    
 
    Each person who is shown in the Note Register as the holder of a particular
principal amount of Class B Notes will be entitled to be treated by the Issuer
Trustee and the Note Trustee as a holder of such principal amount of Class B
Notes and the expression "Class B Noteholder" shall be construed accordingly,
but without prejudice to the entitlement of the holder of the Book-Entry Class B
Note to be paid principal and interest thereon in accordance with its terms.
Such persons shall have no claim directly against the Issuer Trustee in respect
of payment due on the Class B Notes for so long as the Class B Notes are
represented by a Book-Entry Class B Note and the relevant obligations of the
Issuer Trustee will be discharged by payment to the registered holder of the
Book-Entry Class B Note in respect of each amount so paid.
 
    (A) PAYMENTS
 
   
    Interest and principal on each Book-Entry Class B Note will be payable by
the Principal Paying Agent to the Common Depositary provided that:
    
 
    (i) no payment of interest may be made by the Issuer Trustee or any Paying
Agent in the United States of America or the Commonwealth of Australia or their
possessions or into a bank account or to an address in the United States or the
Commonwealth of Australia or their possessions, and
 
    Each of the persons appearing from time to time as the holder of a Class B
Note will be entitled to receive any payment so made in respect of that Class B
Note in accordance with the respective rules and procedures of DTC. Such persons
will have no claim directly against the Issuer Trustee in respect of payments
due on the Class B Notes which must be made by the holder of the relevant
Book-Entry Class B Note, for so long as such Book-Entry Class B Note is
outstanding.
 
    A record of each payment made on a Book-Entry Class B Note, distinguishing
between any payment of principal and any payment of interest, will be recorded
in the Note Register by the Principal Paying Agent, and such record shall be
prima facie evidence that the payment in question has been made.
 
    (B) EXCHANGE
 
    The Book-Entry Class B Note will be exchangeable for definitive Class B
Notes only if:
 
   
    (a) the Trust Manager advises the Principal Paying Agent in writing that the
       Clearing Agency is no longer willing or able properly to discharge its
       responsibilities with respect to the Class A Notes or the Clearing Agency
       ceases to carry on business, and the Trust Manager is unable to locate a
       qualified successor;
    
 
    (b) the Issuer Trustee, at the direction of the Trust Manager (at the Trust
       Manager's option) advises the Principal Paying Agent in writing that the
       book entry system through the Clearing Agency is or is to be terminated;
       or
 
   
    (c) after the occurrence of an Event of Default, the Class B Note Owner's
       representing beneficial interests aggregating to at least a majority of
       the aggregate Invested Amount of the Class B Notes advise the Principal
       Paying Agent and Issuer Trustee through the Clearing Agency in writing
       that the continuation of a book entry system through the Clearing Agency
       is no longer in the best interests of the Note Owners,
    
 
   
then the Principal Paying Agent shall notify all Class B Note Owners and the
Issuer Trustee of the occurrence of any such event and of the availability of
Definitive Notes to Class B Note Owners requesting
    
 
                                     III-23
<PAGE>
   
the same. Upon the surrender of the Book-Entry Notes to the Issuer Trustee by
the Clearing Agency, and the delivery by the Clearing Agency of the relevant
registration instructions to the Issuer Trustee, the Issuer Trustee shall
execute and procure the Principal Paying Agent to authenticate the Definitive
Notes in accordance with the instructions of the Clearing Agency.
    
 
    (C) NOTICES
 
   
    So long as the Notes are represented by the Book-Entry Class B Note and the
same is/are held on behalf of DTC, notices to Class B Noteholders may be given
by delivery of the relevant notice to DTC for communication by them to entitled
account holders in substitution for delivery to each Class B Noteholder as
required by the Class B Conditions.
    
 
    (D) CANCELLATION
 
    Cancellation of any Class B Note required by the Class B Conditions will be
effected by reduction in the principal amount of the relevant Book-Entry Class B
Note.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
Pursuant to Section 109 of the Articles of Association of the Registrant:
 
(1) To the extent permitted by law and without limiting the powers of the
    Registrant, the Registrant must indemnify each person who is, or has been, a
    director or secretary of the Registrant against any liability which results
    directly or indirectly from facts or circumstances relating to the person
    serving or having served in that capacity in relation to the Registrant or
    any of its subsidiaries or in the capacity of an employee of the Registrant
    or any of its subsidiaries:
 
    (a) to any person (other than the Registrant or a related body corporate),
       which does not arise out of conduct involving a lack of good faith or
       conduct known to the person to be wrongful;
 
    (b) for costs and expenses incurred by the person in defending proceedings,
       whether civil or criminal, in which judgment is given in favor of the
       person or in which the person is acquitted, or in connection with any
       application in relation to such proceedings in which the court grants
       relief to the person under the Corporations Law and the Corporations
       Regulations of Australia.
 
(2) The Registrant need not indemnify a person as provided for in paragraph (1)
    in respect of a liability to the extent that the person is entitled to an
    indemnity in respect of that liability under a contract of insurance.
 
(3) To the extent permitted by law and without limiting the powers of the
    Registrant, the board of directors may authorize the Registrant to, and the

    (a) documentary indemnity in favor of; or
 
    (b) insurance policy for the benefit of,
 
    a person who is, or has been, a director, secretary, auditor, employee or
    other officer of the Registrant or of a subsidiary of the Registrant, which
    indemnity or insurance policy may be in such terms as the board of directors
    approves and, in particular, may apply to acts or omissions prior to or
    after the time of entering into the indemnity or policy; and
 
                                      II-1
<PAGE>
(4) The benefit of each indemnity given in paragraph (1) of Section 109
    continues, even after its terms or the terms of this paragraph are modified
    or deleted, in respect of a liability arising out of acts or omissions
    occurring prior to the modification or deletion.

ITEM 17. UNDERTAKINGS.
 
    The undersigned Registrant on behalf of the Westpac Securitization Trust,
Series 1998-1G (the "Trust") hereby undertakes:
 
                                      II-2
<PAGE>
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement;
 
            (i) To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933, as amended (the "Act");
 
            (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement;
 
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.
 
        (2) That, for the purpose of determining any liability under the Act,
    each post-effective amendment that contains a form of prospectus shall be
    deemed to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
        (4) To file a post-effective amendment to the registration statement to
    include any financial statements required by Rule 3-19 at the start of any
    delayed offering or throughout a continuous offering.
 
    Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
    For purposes of determining any liability under the Securities Act of 1933,
the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
    For the purposes of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

Ladies and Gentlemen:

     Westpac Securities Administration Limited, a limited liability public

Class B Mortgage Backed Floating Rate Notes (the "Class B Notes" and together
with the Class A Notes, the "Notes") issued by the Series 1998-1G WST Trust (the
"Trust").  Each Note will be secured by the assets of the Trust.  The assets of
the Trust include, among other things, a pool of variable and fixed rate
residential housing loans (the "Housing Loans") originated or acquired by

Westpac Securitization Management Pty Limited (the "Trust Manager"), which sets
forth specific provisions regarding the Trust and details the provisions of the
Notes.  The Note Trust Deed, dated June  ___, 1998 (the "Note Trust Deed") by
and among the Issuer Trustee, the Trust Manager and Morgan Guaranty Trust
Company of New York (the "Note Trustee") provides for the issuance and
registration of the Notes in accordance with the terms and conditions attached
thereto.  Payments in respect of the Class B Notes are, to the extent specified
in the Note Trust Deed, subordinated to the rights of the holders of the Class A
Notes.  The Mortgage Company Pty Limited will act as servicer (the "Servicer")
of the Housing Loans.  The Trust Manager and Westpac are each a "Westpac Party"
and collectively are referred to herein as the "Westpac Parties."

     The Trust Manager has prepared and filed with the Securities and Exchange
Commission (the "Commission") in accordance with the provisions of the
Securities Act of 1933, as amended, and the rules and regulations of the
Commission thereunder (collectively, the "Securities Act"), a registration
statement, including a prospectus, relating to the Notes.  The registration
statement as amended at the time when it became effective, or, if a
post-effective amendment is filed with respect thereto, as amended by such
post-effective amendment at the time of its effectiveness, including in each
case information (if any) deemed to be part of the registration statement at the
time of effectiveness pursuant to Rule 430A under the Securities Act, is
referred to in this Agreement as the "Registration Statement", and the
prospectus in the form first used to confirm sales of Notes is referred to in
this Agreement as the "Prospectus".  

     When used in this Agreement, "Basic Documents" shall mean the Master Trust
Deed, the Series Notice, the Servicing Agreement, the Notes, the Security Trust
Deed, the Note Trust Deed, the Swap Agreements and the Agency Agreement and any
other contract, agreement or instrument which is or is to be entered into by any
of the Westpac Parties or the Issuer Trustee on the Closing Date or otherwise in
connection with any of the foregoing or this Agreement.  To the extent not
defined herein, capitalized terms used herein have the meanings assigned to such
terms in the Prospectus.

     In this Agreement, a reference to the Issuer Trustee is a reference to the
Issuer Trustee in its capacity as trustee of the Series 1998-1G WST Trust only,
and in no other capacity.  Any reference to the assets, business, property or
undertaking of the Issuer Trustee is a reference to the Issuer Trustee in that

Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including, without limitation, the legal fees and other
expenses incurred in connection with any suit, action or proceeding or any claim
asserted) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or the Prospectus (as
amended or supplemented if the Trust Manager shall have furnished any amendments
or supplements thereto) (other than to the extent any losses, claims, damages or
liabilities arise as a result of any information under the heading "Prepayment
and Yield Considerations"), or caused by any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, except (i) insofar as such losses,
claims, damages or liabilities are caused by any untrue statement or omission or
alleged untrue statement or omission made in reliance upon and in conformity
with information relating to any Underwriter furnished to the Trust Manager in
writing by such Underwriter through the Representatives expressly for use
therein or (ii) that such indemnity with respect to the Prospectus shall not
inure to the benefit of any Underwriter (or any person controlling any
Underwriter) from whom the person asserting any such loss, claim, damage or
liability purchased the Offered Notes which are the subject thereof if such
person did not receive a copy of the Prospectus (or the Prospectus as amended or
supplemented) at or prior to the confirmation of the sale of such Offered Notes
to such person in any case where such delivery is required by the Act and the
untrue statement or omission of a material fact contained in such Prospectus was
corrected in the Prospectus (or the Prospectus as amended or supplemented);

     (b)  To the extent that any payment of damages by Westpac pursuant to
subsection 7(a) above is determined to be a payment of damages pursuant to
"Funds Management and Securitisation Prudential Statement C2" such payment shall
be subject to the terms of Section 89 therein.

     (c)  Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Trust Manager, its directors, its officers who sign the
Registration Statement, the Issuer Trustee and Westpac and each person who
controls any of the Westpac Parties or the Issuer Trustee within the meaning of
Section 15 of the Securities Act and Section 20 of the Exchange Act to the same
extent as the foregoing indemnity from the Westpac Parties or 


                                          18
<PAGE>

the Issuer Trustee to each Underwriter, but only with reference to information
relating to such Underwriter furnished to the Trust Manager in writing by such
Underwriter through the Representatives expressly for use in the Registration
Statement, the Prospectus, any amendment or supplement thereto.

     (d)  If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to Subsections
(a) or (b) above, such person (the "Indemnified Person") shall promptly notify
the person against whom such indemnity may be sought (the "Indemnifying Person")
in writing, and the Indemnifying Person, upon request of the Indemnified Person,
shall retain counsel reasonably satisfactory to the Indemnified Person to
represent the Indemnified Person and any others the Indemnifying Person may
designate in such proceeding and shall pay the fees and expenses of such counsel
related to such proceeding.  In any such proceeding, any Indemnified Person
shall have the right to retain its own counsel, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed to the
contrary, (ii) the Indemnifying Person has failed within a reasonable time to
retain counsel reasonably satisfactory to the Indemnified Person or (iii) the
named parties in any such proceeding (including any impleaded parties) include
both the Indemnifying Person and the Indemnified Person and representation of
both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them.  It is understood that the
Indemnifying Person shall not, in connection with any proceeding or related
proceeding in the same jurisdiction, be liable for the fees and expenses of more
than one separate firm (in addition to any local counsel) for all Indemnified
Persons, and that all such fees and expenses shall be reimbursed as they are
incurred.  Any such separate firm for the Underwriters, each affiliate of any
Underwriter which assists such Underwriter in the distribution of the Notes, and
such control persons of Underwriters shall be designated in writing by the
Representatives and any such separate firm for the Trust Manager, its directors,
its officers who sign the Registration Statement, the Issuer Trustee and Westpac
and such control persons of any of the Westpac Parties or the Issuer Trustee
shall be designated in writing by the Trust Manager.  The Indemnifying Person
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Person agrees to indemnify any
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment.  Notwithstanding the foregoing sentence, if at any time
an Indemnified Person shall have requested an Indemnifying Person to reimburse
the Indemnified Person for fees and expenses of counsel as contemplated by the
third sentence of this subsection (c), the Indemnifying Person agrees that it
shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such Indemnifying Person of the aforesaid request and (ii) such
Indemnifying Person shall not have reimbursed the Indemnified Person in
accordance with such request prior to the date of such settlement.  No
Indemnifying Person shall, without the prior written consent of the Indemnified
Person, effect any settlement of any pending or threatened proceeding in respect
of which any Indemnified Person is or could have been a 


                                          19
<PAGE>

party and indemnity could have been sought hereunder by such Indemnified Person,
unless such settlement includes an unconditional release of such Indemnified
Person from all liability on claims that are the subject matter of such
proceeding.

     (e)  If the indemnification provided for in subsections (a) or (b) above is
unavailable to an Indemnified Person in respect of any losses, claims, damages
or liabilities referred to therein, then each Indemnifying Person under such
subsection, in lieu of indemnifying such Indemnified Person thereunder, shall
contribute to the amount paid or payable by such Indemnified Person as a result
of such losses, claims, damages or liabilities in such proportion as is
appropriate to reflect the relative benefits received by the Westpac Parties and
the Issuer Trustee on the one hand and the Underwriters on the other hand from
the offering of the Notes and also the relative fault of the Westpac Parties and
the Issuer Trustee on the one hand and the Underwriters on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative benefits received by the Westpac Parties and the
Issuer Trustee on the one hand and the Underwriters on the other shall be deemed
to be in the same respective proportions as the net proceeds from the offering
(before deducting expenses) received by the Westpac Parties and the Issuer
Trustee and the total underwriting discounts and the commissions received by the
Underwriters bear to the aggregate public offering price of the Notes.  The
relative fault of the Westpac Parties and the Issuer Trustee on the one hand and
the Underwriters on the other shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Westpac Parties or the Issuer Trustee or by the Underwriters and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

     The Westpac Parties, the Issuer Trustee and the Underwriters agree that it
would not be just and equitable if contribution pursuant to this Section 7 were
determined by PRO RATA allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in the immediately preceding
paragraph.  The amount paid or payable by an Indemnified Person as a result of
the losses, claims, damages and liabilities referred to in this subsection (d)
shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses incurred by such Indemnified Person in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 7, in no event shall an Underwriter be required to
contribute any amount in excess of the amount by which the total price at which
the Notes underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages that such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations to contribute 


                                          20
<PAGE>

pursuant to this Section 7 are several in proportion to the respective principal
amount of Notes set forth opposite their names in Schedule I hereto, and not
joint.

     The remedies provided for in this Section 7 are not exclusive and shall not
limit any rights or remedies which may otherwise be available to any indemnified
party at law or in equity.

     (f)  The indemnity and contribution agreements contained in this Section 7
and the representations and warranties of the Westpac Parties or the Issuer
Trustee set forth in this Agreement shall remain operative and in full force and
effect regardless of (i) any termination of this Agreement, (ii) any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter or by or on behalf of the Westpac Parties or the Issuer Trustee,
its officers or directors or any other person controlling the Westpac Parties or
the Issuer Trustee and (iii) acceptance of and payment for any of the Notes.

     8.   TERMINATION.  Notwithstanding anything herein contained, this
Agreement may be terminated in the absolute discretion of the Representatives,
by notice given to the Trust Manager, if after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock Exchange, (ii) trading of any securities of or guaranteed by any
of the Westpac Parties or the Issuer Trustee shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York, Sydney, Australia or London, England
shall have been declared by either Federal or New York or related authorities,
or (iv) there shall have occurred any outbreak or escalation of hostilities or
any change in financial markets or any calamity or crisis that, in the judgment
of the Representatives, is material and adverse and which, in the judgment of
the Representatives, makes it impracticable to market the Notes on the terms and
in the manner contemplated in the Prospectus.

     9.   EFFECTIVENESS OF AGREEMENT; DEFAULT OF UNDERWRITERS.  This Agreement
shall become effective upon the later of (x) execution and delivery hereof by
the parties hereto and (y) release of notification of the effectiveness of the
Registration Statement (or, if applicable, any post-effective amendment) by the
Commission.

     If on the Closing Date any one or more of the Underwriters shall fail or
refuse to purchase Notes which it or they have agreed to purchase hereunder on
such date, and the aggregate principal amount of Notes which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not more
than one-tenth of the aggregate principal amount of the Notes to be purchased on
such date, the other Underwriters shall be obligated severally in the
proportions that the principal amount of Notes set forth opposite their
respective names in Schedule I bears to the aggregate principal amount of Notes
set forth opposite the names of all such non-defaulting Underwriters, or in such
other proportions as the Representatives may specify, to purchase the Notes
which such defaulting Underwriter or 


                                          21
<PAGE>

Underwriters agreed but failed or refused to purchase on such date; PROVIDED
that in no event shall the principal amount of Notes that any Underwriter has
agreed to purchase pursuant to Section 1 be increased pursuant to this Section 9
by an amount in excess of one-ninth of such principal amount of Notes without
the written consent of such Underwriter.  If on the Closing Date any Underwriter
or Underwriters shall fail or refuse to purchase Notes which it or they have
agreed to purchase hereunder on such date, and the aggregate principal amount of
Notes with respect to which such default occurs is more than one-tenth of the
aggregate principal amount of Notes to be purchased on such date, and
arrangements satisfactory to the Representatives and the Trust Manager for the
purchase of such Notes are not made within 36 hours after such default, this
Agreement shall terminate without liability on the part of any non-defaulting
Underwriter or the Trust Manager.  In any such case either you or the Trust
Manager shall have the right to postpone the Closing Date, but in no event for
longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected.  Any action taken under this paragraph shall not
relieve any defaulting Underwriter from liability in respect of any default of
such Underwriter under this Agreement.

     10.  EXPENSES UPON TERMINATION.  If this Agreement shall be terminated by
the Underwriters, or any of them, because of any failure or refusal on the part
of the Westpac Parties or the Issuer Trustee to comply with the terms or to
fulfill any of the conditions of this Agreement, or if for any reason any of the
Westpac Parties or the Issuer Trustee shall be unable to perform its obligations
under this Agreement or any condition of the Underwriters' obligations cannot be
fulfilled, Westpac agrees to reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and expenses of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

     11.  SELLING RESTRICTIONS.  (a) No prospectus in relation to the Notes has
been lodged with, or registered by, the Australian Securities Commission or the
Australian Stock Exchange Limited.  Each Underwriter represents and agrees that
in connection with the initial distribution of the Notes:

          (i)    it has not (directly or indirectly) offered for subscription
                 or purchase or issued invitations to subscribe for or buy nor
                 has it sold, the Notes,

          (ii)   will not (directly or indirectly) offer for subscription or
                 purchase or issue invitations to subscribe for or buy nor will
                 it sell the Notes, and

          (iii)  has not distributed and will not distribute any prospectus, or
                 any advertisement or other offering material

          in the Commonwealth of Australia, its territories or possessions
          ("Australia") or to any person who is actually known by the
          Underwriter (without an



                                          22
<PAGE>

          obligation on the Underwriter to make any inquiry) to be a resident of
          Australia for the purposes of section 128F of the Income Tax
          Assessment Act 1936 of Australia (the "Tax Act") or to any associates
          of Westpac identified on Annex A hereto or as otherwise notified in
          writing by Westpac to the Underwriters from time to time.

     (b)  Each Underwriter (severally, not jointly) undertakes that the issue of
          Offered Notes governed by this Agreement resulted from:

          (a)    an offer by such Underwriter within 30 days of issue to any
                 person as a result of negotiations being initiated in
                 electronic form (specifying the particular electronic screen
                 or service), the Prospectus or in such other form as may be
                 applicable, being a form that is used by the financial markets
                 for dealing in securities; or

          (b)    its offer of the Notes for sale within 30 days of issue to at
                 least 10 persons who are in the business of providing finance
                 or investing or dealing in securities in financial markets
                 each of whom was not known to be an associate of any of the
                 others (within the meaning of section 128F of the Tax Act),

          and in either case it has announced on behalf of the Issuer Trustee in
          relation to the offer that Morgan Guaranty Trust Company of New York,
          Brussels office, as operator of the Euroclear System ("Euroclear") or
          Cedel Bank SOCIETE ANONYME ("Cedel Bank") will confer rights in the
          Notes under Book-Entry Notes.  Each Underwriter will provide the
          Issuer Trustee (within five Business Day of the offer of Notes by it)
          a written statement which sets out details of the relevant offer.

          Each Underwriter (severally, not jointly) agrees to co-operate with
          reasonable requests from the Issuer Trustee for information for the
          purposes of assisting the Issuer Trustee to demonstrate that the
          public offer test under section 128F of the Tax Act has been
          satisfied, provided that no Underwriter shall be obliged to disclose
          the identity of the purchaser of any Note or any information from
          which such identity might/would be capable of being ascertained, or
          any information the disclosure of which would be contrary to or
          prohibited by any relevant law, regulation or directive.

     (c)  Each Underwriter acknowledges that no representation is made by the
          Issuer Trustee or any Underwriter that any action has been or will be
          taken in any jurisdiction by the Issuer Trustee or any Underwriter
          that would permit a public offering of the Notes, or possession or
          distribution of the Prospectus or any other offering material, in any
          country or jurisdiction where action for that purpose is required. 
          Each Underwriter will comply with all applicable 


                                          23
<PAGE>

          securities law and regulations in each jurisdiction in which it
          purchases, offers, sell or delivers Notes or has in its possession or
          distributes the Prospectus or any other offering material, in all
          cases at its own expense.


     12.  CERTAIN MATTERS RELATING TO THE ISSUER TRUSTEE.  The Issuer Trustee
enters into this Agreement only in its capacity as trustee of the Trust and in
no other capacity.  A liability arising under or in connection with this
Agreement or the Trust can be enforced against the Issuer Trustee only to the
extent to which it can be satisfied out of assets of the Trust out of which the
Issuer Trustee is actually indemnified for such liability.  This limitation of
the Issuer Trustee's liability applies despite any other provisions of this
Agreement and extends to all liabilities and obligations of the Issuer Trustee
in any way connected with any representation, warranty, conduct, omission,
agreement or Transaction related to this Agreement or the Trust.

     The parties other than the Issuer Trustee may not sue the Issuer Trustee in
any capacity other than as trustee of the Trust or seek the appointment of a
receiver (except under the Security Trust Deed) or a liquidator, an
administrator or any other similar person to the Issuer Trustee or prove in any
liquidation, administration or arrangements of or affecting the Issuer Trustee.

     The provisions of this clause 12 shall not apply to any obligation or
liability of the Issuer Trustee to the extent that it is not satisfied because
under the Master Trust Deed or by operation of law there is a reduction in the
extent of the Issuer Trustee's indemnification out of the assets of the Trust as
a result of the Issuer Trustee's fraud, negligence or breach of trust.

     It is acknowledged that the Trust Manager, the Servicer, the Currency Swap
Providers, the Note Trustee, the Principal Paying Agent, the other Paying Agents
and the Agent Bank (each, a "Relevant Party") are responsible under the
Transaction Documents (as defined in the Master Trust Deed) for performing a
variety of obligations relating to the Trust.  No act or omission of the Issuer
Trustee (including any related failure to satisfy its obligations under the
Transaction Documents) will be considered fraud, negligence or breach of trust
of the Issuer Trustee for the purpose of this Agreement to the extent to which
the act or omission was caused or contributed to by any failure by any Relevant
Party or any other person who provides services in respect of the Trust (other
than a person who has been delegated or appointed by the Issuer Trustee and for
whom the Issuer Trustee is responsible under the relevant Transaction Document,
but excluding any Relevant Party) to fulfil its obligations relating to the
Trust or by any other act or omission of a Relevant Party or by any other person
who provides services in respect of the Issuer Trustee (other than a person who
has been delegated or appointed by the Issuer Trustee and for whom the Issuer
Trustee is responsible under the Transaction Documents, but excluding any
Relevant Party).

     13.  SUCCESSORS.  This Agreement shall inure to the benefit of and be
binding upon the Westpac Parties, the Issuer Trustee, the Underwriters, each
affiliate of any Underwriter which assists such Underwriter in the distribution
of the Notes, any controlling persons referred to herein and their respective
successors and assigns.  Nothing expressed or mentioned in this Agreement is
intended or shall be construed to give any other person, firm or corporation any
legal or equitable right, remedy or claim under or in respect of this Agreement
or any provision herein contained.  No purchaser of Notes from any Underwriter
shall be deemed to be a successor by reason merely of such purchase.

     14.  ACTIONS BY REPRESENTATIVES; NOTICES.  Any action by the Underwriters
hereunder may be taken by the Representatives jointly or by J.P. Morgan
Securities Inc. alone on behalf of the Underwriters, and any such action taken
by the Representatives jointly or by J.P. Morgan Securities Inc. alone shall be
binding upon the Underwriters.  All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the
Underwriters shall be given to [the Representatives c/o J.P. Morgan Securities

constitute one and the same instrument.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without giving

            Agency for each Class of Notes has confirmed in writing that that
            agreement would not result in a downgrading of the rating given to
            any relevant Note or the withdrawal of the rating of any relevant
            Note),

      calculate the Threshold Rate as at that date and notify the Trustee, the
      Servicer and Westpac of that Threshold Rate on the relevant Payment Date.

      Purchased Receivable which is subject to a variable rate set, as permitted

11.3 Trustee Setting Threshold Rate

      If the Trustee does not receive notice from the Servicer under clause 11.2
      within 7 Business Days following the date on which the Basis Swap is

      under the Transaction Documents, including, without limitation, taking
      action against the Servicer, to ensure that the interest rate payable on
      each Purchased Receivable which is subject to a variable rate set, as

            interest of the Trust subject to rights of holders of Residual
            Income Unit. The Residual Capital Unit may not be redeemed at any

      The Servicer makes the following representations and warranties for the
      benefit of the Trustee in relation to the Sale Notice referred to in
      clause 15 and the Receivables, Receivable Rights and Related Securities
      referred to in that Sale Notice.

      (a)   (Eligible Receivable) As at the Cut-Off Date, each Receivable which
            is specified in that Sale Notice is an Eligible Receivable. In
            relation to any related Receivable Security that is required to be
            registered with any Governmental Agency and which is not registered
            at the Cut-Off Date, it will be registered.

      (b)   (Receivable Securities) The Servicer has not done, or omitted to do,
            anything which would prevent each Receivable, Receivable Security
            and Related Security which is specified in that Sale Notice from
            being valid, binding and enforceable against the relevant 
- --------------------------------------------------------------------------------
<PAGE>

            Obligor(s) in all material respects except to the extent that it is
            affected by laws relating to creditors rights generally, or
            doctrines of equity.

      (c)   (Ownership) In relation to each Receivable Security which is
            specified in that Sale Notice the Servicer has not done, or omitted
            to do anything which would prevent the relevant Obligor(s) from
            being the sole legal owner of the relevant Mortgaged Property and
            registered as the sole proprietor(s) of the relevant Mortgaged
            Property.

      (d)   (Insurance) As at the Closing Date, each Receivable which is
            specified in the Sale Notice is the subject of a Mortgage Insurance
            Policy from a Mortgage Insurer for the scheduled term of that
            Receivable. The sale of each such Receivable to the Trustee is not
            contrary to the relevant Mortgage Insurance Policy. The Servicer has
            not done or omitted to do anything which might prejudicially affect
            or limit the rights of the Trustee under or in respect of a Mortgage
            Insurance Policy to the extent that those rights relate to that
            Receivable or the related Receivable Security. On transfer to the
            Trustee of equitable title to a Purchased Receivable, the Trustee
            will have the benefit of the relevant Mortgage Insurance Policy for
            that Receivable.

      (e)   (Solvency of Mortgage Insurers) The officers of the Servicer who
            have responsibility for the transactions contemplated by the
            Transaction Documents do not have actual notice that any insurer
            under any insurance policy in relation to a Receivable is insolvent
            or will be unable to pay a valid claim.

      (f)   (Selection process) There is no fraud, dishonesty, material
            misrepresentation or negligence on the part of the Servicer in
            connection with the selection and offer to the Trustee of any
            Receivables or related Receivable Securities which is specified in
            that Sale Notice.

      (g)   (Relevant Documents) The Servicer holds in its possession or control
            all Relevant Documents that relate to the Receivables and the
            related Receivable Securities which are specified in that Sale
            Notice necessary to enforce the provisions of and the security
            created by the relevant Receivable Securities.

            or Receivable Securities which are specified in that Sale Notice
            were satisfied, cancelled, discharged or rescinded and the Mortgaged
            Property relating to each relevant Receivable and Receivable
            Security had not been released from the security of the relevant
            Receivable Securities.

      (i)   (Interest rate) Except as may be provided in a Receivable Agreement
            or Receivable Security which is specified in the Sale Notice, and
            subject to applicable laws, the Servicer has not done, or omitted to
            do anything which would render the interest rate for each such
            Receivable subject to any limitation, or to any consent, additional
            memoranda or other writing required from the relevant Obligor to
            give effect to a change in that rate and any change in that rate
            will be effective on notice being given to the that Obligor in
            accordance with the terms of the relevant Receivable or Receivable
            Security.

      (j)   (Assignability) All consents required in relation to the assignment
            of the Receivables and the related Receivable Rights specified in
            that Sale Notice have been obtained. Those Receivables and
            Receivable Rights are assignable.

      (k)   (Servicing) Each relevant Receivable referred to in the Sale Notice
            and each Receivable Security and Related Security has been serviced
            by the Servicer in accordance with the Servicing Agreement, the
            Servicing Agreement Series 1997-2 Amendment Agreement dated 23 April
            1997, the Servicing Agreement Series 1997-3 Amendment Agreement
            dated 25 June 1997 and the Servicing Agreement Series 1997-4E
            Amendment Agreement dated 29 September 1997 from the time of its
            transfer from Westpac to the Series 1997-1 WST Trust, the Series
            1997-2 WST Trust, the Series 1997-3 WST Trust or the Series 
- --------------------------------------------------------------------------------
<PAGE>

            1997-4E WST Trust, as the case may be, until the Closing Date. That
            servicing includes, without limitation, ensuring compliance with the
            Consumer Credit code in connection with servicing the Receivables
            and Receivable Securities where failure to do so would have an
            Adverse Effect.

      (l)   (Ordinary course of business) Between the Cut-Off Date and the
            Closing Date, the Servicer dealt with the Receivables and the
            Receivable Securities specified in the Sale Notice in the ordinary
            course of its business.

            Security Trust Deed given by the Warehouse Trustee in favour of the

            charge over those Receivables and related Receivable Rights.

      (b)   (Receivable Securities) The Warehouse Trustee has not done anything,
            during the period within which the Warehouse Trustee was trustee of
            the Receivables and the related Receivable Rights specified in that
            Sale Notice, which would prevent each Receivable, Receivable
            Security and Related Security which is specified in that Sale Notice
            from being valid, binding and enforceable against the relevant
            Obligor(s) in all material respects except to the extent that it is
            affected by laws relating to creditors rights generally, or
            doctrines of equity.

      (c)   (Set Off) The Warehouse Trustee has not done anything, during the
            period within which the Warehouse Trustee was trustee of the
            Receivables and the related Receivable Rights specified in that Sale
            Notice, which would render, once equitably assigned to the Trustee,
            any Receivable or Receivable Right which is specified in that Sale
            Notice subject to any right of rescission, set off, counterclaim or
            similar defence, nor to render any Receivable or Receivable Right
            which is specified in that Sale Notice subject to, or affected by,
            any interest off-set arrangement or right.

            Warehouse Trustee's interest in the Receivables and the related
            Receivable Rights which are specified in that Sale Notice, will not
            constitute a breach of any Relevant Document or the Warehouse
            Trustee's obligations or a default by the Warehouse Trustee under
            any Security Interest.

      (e)   (Solvency) The Warehouse Trustee is solvent.

            of the Receivables and the related Receivable Rights specified in
            the Sale Notice have been obtained. Those Receivables and Receivable
            Rights are assignable.

      (b)   (Quality of Title) It is the sole, legal and beneficial owner of the
            Receivables and the related Receivable Rights specified in the Sale
            Notice. Those Receivables and the related Receivable Rights,
            together with the interest of Westpac under the Relevant Documents,
            are owned by it free and clear of any Security Interest (other than
            any Security Interest arising solely as the result of any action
            taken by the Trustee).

      (c)   (Eligible Receivable) As at the Cut-Off Date, each Receivable which
            is specified in the Sale Notice is an Eligible Receivable. In
            relation to any related Receivable Security that is required to be
            registered with any Governmental Agency and which is not registered
            at the Cut-Off Date, it will be registered.

      (d)   (Receivable Securities) Each Receivable, Receivable Security and
            Related Security which is specified in the Sale Notice is valid,
            binding and enforceable against the relevant Obligor(s) in all
            material respects except to the extent that it is affected by laws
            relating to creditors rights generally, or doctrines of equity.

      (e)   (Set Off) Once equitably assigned to the Trustee, no Receivable or
            Receivable Right which is specified in the Sale Notice will be
            subject to any right of rescission, set off, counterclaim or similar
            defence. No Receivable or Receivable Right which is specified in
            that Sale Notice is subject to, or affected by, any interest off-set
            arrangement or right.

      (f)   (Compliance with Laws) At the time each Receivable and Receivable
            Security which is specified in the Sale Notice and each Related
            Security was entered into it complied in all material respects with
            applicable laws, including, without limitation, where the Consumer
            Credit Legislation applies, the Consumer Credit Legislation.

      (g)   (Ownership) In relation to each Receivable Security which is
            specified in the Sale Notice the relevant Obligor(s) is or are the
            sole legal owner of the relevant Mortgaged Property and registered
            as the sole proprietor(s) of the relevant Mortgaged Property.

      (h)   (Insurance) As at the Closing Date, each Receivable which is
            specified in the Sale Notice is the subject of a Mortgage Insurance
            Policy from a Mortgage Insurer for the scheduled term of that
            Receivable. The sale of each such Receivable to the Trustee is not
            contrary to the relevant Mortgage Insurance Policy. Westpac has not
            done or omitted to do anything which might prejudicially affect or
            limit its rights or the rights of the Trustee under or in respect of
            a Mortgage Insurance Policy to the extent that those rights relate
            to that Receivable or the related Receivable Security. On transfer
            to the Trustee of equitable title to a Purchased Receivable, the
            Trustee will have the benefit of the relevant Mortgage Insurance
            Policy for that Receivable.

      (i)   (Solvency of Mortgage Insurers) The officers of Westpac who have
            responsibility for the

            actual notice that any insurer under any insurance policy in
            relation to a Receivable is insolvent or will be unable to pay a
            valid claim.

      (j)   (Selection process) There is no fraud, dishonesty, material
            misrepresentation or negligence on the part of Westpac in connection
            with the selection and offer to the Trustee of any Receivables or
            related Receivable Securities which is specified in the Sale Notice.

      (k)   (No void transactions) The assignment of the Receivables and
            Receivable Rights which are specified in the Sale Notice will not be
            held by a court to be an undervalue transfer, a fraudulent
            conveyance, or a voidable preference under any law relating to
            insolvency.

      (l)   (Security Interest) The sale, transfer and assignment of Westpac's
            interest in the Receivables and the related Receivable Rights which
            are specified in a Sale Notice, will not constitute a breach of any
            Relevant Document or Westpac's obligations or a default by Westpac
            under any Security Interest.

      (m)   (Relevant Documents) Westpac holds in its possession or control all
            Relevant Documents that relate to the Receivables and the related
            Receivable Securities which are specified in the Sale Notice
            necessary to enforce the provisions of and the security created by
            the relevant Receivable Securities.

      (n)   (Solvency) Westpac is solvent.

      (o)   (No recision, etc) As at the Cut-Off Date, none of the Receivables
            or Receivable Securities which are specified in the Sale Notice were
            satisfied, cancelled, discharged or rescinded and the Mortgaged
            Property relating to each relevant Receivable and Receivable
            Security had not been released from the security of the relevant
            Receivable Securities.

      (p)   (Interest rate) Except as may be provided in a Receivable Agreement
            or Receivable Security which is specified in the Sale Notice, and
            subject to applicable laws, the interest rate for each such
            Receivable is not subject to any limitation, no consent, additional
            memoranda or other writing is required from the relevant Obligor to
            give effect to a change in that rate and any change in that rate
            will be effective on notice being given to the that Obligor in
            accordance with the terms of the relevant Receivable or Receivable
            Security.

      (q)   (Ordinary course of business) Between the Cut-Off Date and the
            Closing Date, Westpac dealt with the Receivables and the Receivable
            Securities specified in the Sale Notice in the ordinary course of
            its business.

      Westpac also makes the following representations and warranties in
      relation to the Receivables and Receivable Rights referred to in the Sale
      Notice given by the Warehouse Trustee:

      (i)   (Sale to earlier Series) Those Receivables and Receivable Rights
            were assigned by Westpac to either the Series 1997-1 WST Trust, the
            Series 1997-2 WST Trust, the Series 1997-3 WST Trust or the Series
            1997-4E WST Trust.

     (ii)   (Representations and Warranties) At the time of those assignments
            Westpac gave the same representations and warranties to the trustee
            of the Series 1997-1 WST Trust, the Series 1997-2 WST Trust, the
            Series 1997-3 WST Trust or the Series 1997-4E WST Trust, as the case
            may be, in relation to those Receivables and Receivable Rights as it
            has given to the Trustee in relation to the Sale Notice given by
            Westpac to the Trustee. The only difference is that in relation to
            the sale to the trustee of the Series 1997-1 WST Trust Westpac did
            not represent and warrant that on transfer to the trustee of the
            Series 1997-1 WST Trust of equitable title to a Purchased
            Receivable, the Trustee will have the benefit of the relevant
            Mortgage Insurance Policy for that Receivable. That representation
            and warranty is given by the Servicer in clause 16(d) of this Series
            Notice.

            Notice as if the transferee was originally a party to the Master
            Trust Deed and this Series Notice.

      14.13 Payments to transferee

      Subject to the Master Trust Deed (including clause 35.1 of the Master
      Trust Deed), on the entry of a transferee of Registered Notes in the
      Register the transferee shall become entitled to receive any payments then

      (including whether or not the entitlement to payment wholly or partly

      for any such payment made to the transferee).

      14.14 Transmission of entitlements

      (a)   (Election) Any person becoming entitled to Registered Notes as a
            result of the death, mental incapacity or bankruptcy of a Registered
            Noteholder may, on producing such evidence as the Trustee requires
            of their entitlement, elect to be either registered as the

            execute a Note Transfer in relation to the Registered Notes in
            favour of that person. All the provisions of the Master Trust Deed
            and this Series Notice relating to the transfer of Registered Notes
            and the registration of Note Transfers shall be applicable to any
            such notice or Note Transfer as if the death, mental incapacity or
            bankruptcy of the Registered Noteholder had not occurred and the
            notice or Note Transfer was a Note Transfer executed by the
            Registered Noteholder.

      (c)   (Discharge) A person entitled to Registered Notes under this clause
            shall be entitled to receive and may give a good discharge for all
            moneys payable in respect of such Registered Notes but, except as
            otherwise provided by the Master Trust Deed and this Series Notice,
            shall not be entitled to any of the rights or privileges of a
            Registered Noteholder unless and until the person is entered in the
            Register as the holder of those Registered Notes.

      14.15 Marked Note Transfer

      (a)   (Entitlement to marking) A Registered Noteholder may from time to

            the Trustee and the Trustee shall mark the Note Transfer in such
            manner as agreed from time to time by the Trustee and the Trust
            Manager and issue the same to the Registered Noteholder.

      (c)   (Trustee will not register transfer) Until the expiry of 90 days (or
            any substitute period as the Trustee and Trust Manager agree from
            time to time and as advised to Registered Noteholders) from the date
            on which the Note Transfer was marked, the Trustee shall not
            register any transfer of Registered Notes relating to the Marked
            Note Transfer otherwise than on that Marked Note Transfer.

            Noteholder by personal delivery at the time the Registered
            Noteholder attends the offices of the Trustee (or such other place
            nominated by the Trustee) for the marking of the Note Transfer by
            the Trustee.

      14.16 Reliance on documents

      The Trustee shall be entitled to accept and assume the authenticity and
      genuineness of any Note Transfer or other document produced to it to be
      duly executed. The Trustee shall not be bound to enquire into the
      authenticity or genuineness of any Note Transfer or other document, nor
      shall it incur any liability for registering any Note Transfer which is
      subsequently discovered to be a forgery or otherwise defective, unless the
      Trustee had actual notice of such forgery or defect at the time of
      registration of such Note Transfer.

      14.17 Specimen signatures

      The Trustee may (but need not) require each Registered Noteholder to
      submit specimen signatures (and in the case of a corporation may require
      those signatures to be authenticated by the secretary or director of such
      Registered Noteholder) of persons authorised to execute Note Transfers on
      behalf of such Registered Noteholder and shall be entitled to assume
      (until notified to the contrary) that such authority has not been revoked.

      14.18 Notes lodged with Austraclear

      If Registered Notes are lodged into the Austraclear System, the Trustee
      shall enter Austraclear in the Register as the holder of those Registered
      Notes. While those Registered Notes remain in the Austraclear System:

      (a)   all payments and notices required of the Trustee and the Trust
            Manager in relation to those Registered Notes will be directed to
            Austraclear; and

      (b)   all dealings (including transfers) and payments in relation to those
            Registered Notes within the Austraclear System will be governed by
            the Austraclear Regulations and need not comply with this clause 14
            to the extent of any inconsistency.

      15.   NOTE ACKNOWLEDGEMENT

      15.1  Issue of Note Acknowledgement

      Notes, as soon as practicable (and in any event no later than 5 Business
      Days or such shorter period specified in the relevant Series Notice or as
      otherwise agreed by the Trustee with the person or the Trust Manager)
      thereafter, the Trustee shall issue a Note Acknowledgement to that person
      in respect of those Registered Notes. If the person has been entered into
      the Register under a Note Transfer and the transferor continues to retain
      a holding of Registered Notes, the Trustee shall within the same period
      stated above issue to the transferor a Note Acknowledgement in respect of
      that retained holding of Registered Notes. No certificates will be issued
      in respect of Registered Notes.

      15.2  Note Acknowledgement not certificate of title
- --------------------------------------------------------------------------------
<PAGE>

      A Note Acknowledgement shall not be a certificate of title as to
      Registered Notes and the Register shall be the only conclusive evidence of
      the ownership of Registered Notes and the entitlements under them. A Note
      Acknowledgement cannot be pledged or deposited as security nor can a
      Registered Note be transferred by delivery of only a Note Acknowledgement.

      15.3  Execution of Note Acknowledgement

      Each Note Acknowledgement shall be signed on behalf of the Trustee
      manually, or in facsimile by mechanical or electronic means, by any
      Authorised Signatory of the Trustee. If any Authorised Signatory of the
      Trustee whose signature appears on a Note Acknowledgement dies or
      otherwise ceases to be an Authorised Signatory before the Note
      Acknowledgement has been issued, the Trustee may nevertheless issue the
      Note Acknowledgement.

      15.4  More than one Note Acknowledgement

      If a Registered Noteholder wishes to receive more than one Note
      Acknowledgement it shall return its Note Acknowledgement to the Trustee
      and at the same time request in writing the issue of a specified number of
      separate Note Acknowledgements. Subject to clause 10.5, the Trustee shall
      then cancel the original Note Acknowledgement and issue in lieu separate
      Note Acknowledgements. A fee prescribed by the Trustee (not exceeding $10
      for each Note Acknowledgement) shall be paid by the Registered Noteholder
      to the Trustee.

      15.5  Worn out, defaced or lost Note Acknowledgement

      If any Note Acknowledgement is worn out or defaced then on production to
      the Trustee it may cancel the same and may issue a new Note
      Acknowledgement. If any Note Acknowledgement is lost or destroyed then on
      proof to the satisfaction of the Trustee, and on such indemnity as the
      Trustee may consider adequate having been given, a new Note
      Acknowledgement shall be given to the person entitled to such lost or
      destroyed Note Acknowledgement. An entry as to the issue of the new Note
      Acknowledgement and of the indemnity (if any) shall be made in the
      Register. A fee prescribed by the Trustee (not exceeding $10) shall be
      paid by the person requesting the new Note Acknowledgement to the Trustee.

      15.6  Joint holdings

      If a single parcel of Registered Notes is held by more than one person,
      only the person whose name stands first in the Register in relation to
      that parcel of Registered Notes shall be entitled to:

      (a)   be issued the relevant Note Acknowledgement and, if applicable, a
            Marked Note Transfer;

      (b)   be given any notices; and

      (c)   be paid any moneys due in respect of such Registered Notes.

      15.7  Delivery of Note Acknowledgement

      A Note Acknowledgement may be sent to the relevant Registered Noteholder
      by mail or by personal delivery to the Registered Noteholder's address
      appearing in the Register and the Note Acknowledgement so sent shall be at
      the risk of that Registered Noteholder.

      (b)   (Declaration) At any meeting, unless a poll is (before or on the
            declaration of the result of the show of hands) demanded, a
            declaration by the chairman that a resolution has been carried by a
            particular majority or lost or not carried by any particular

            representing, in aggregate not less than 2% of the Registered Notes
            or constituting the Class (as the case may be) and then outstanding,

            meeting at which the poll was demanded as at the date of the taking
            of the poll. The demand for a poll shall not prevent 
- --------------------------------------------------------------------------------
<PAGE>

            the continuance of the meeting for the transaction of any business
            other than the question on which the poll has been demanded. The

      (d)   (No adjournment) Any poll demanded at any meeting on the election of
            a chairman or on any question of adjournment shall be taken at the
            meeting without adjournment.

                  respect of which he or she is a Representative as stated in
                  the relevant Register at the date the notices are dispatched
                  to Registered Noteholders for the meeting.

            Any person entitled to more than one vote need not use all his or
            her votes or cast all his or her votes to which he or she is
            entitled in the same way.

      17.8  Right to attend and speak

      The Trustee, the Trust Manager and the relevant Beneficiary (through their
      respective representatives) and their respective financial and legal
      advisers shall be entitled to attend and speak at any meeting of the
      Registered Noteholders or any Class (as the case may be). No person shall
      otherwise be entitled to attend or vote at any meeting of the Registered
      Noteholders or any Class (as the case may be) unless he or she holds

            the time appointed for holding the meeting or adjourned meeting at
            which the named proxy proposes to vote and in default, the
            instrument or proxy shall be treated as invalid unless the chairman
            of the meeting decides otherwise before such meeting or adjourned
            meeting proceeds to business. A notarially certified copy proof (if
            applicable) of due execution shall if required by the Trustee be
            produced by the proxy at the meeting or adjourned meeting but the
            Trustee shall not be obliged to investigate or be concerned with the
            validity of, or the authority of, the proxy named in any such
            instrument. Any person may act as a proxy whether or not that person
            is a Registered Noteholder.

      (b)   (Proxy remains valid) Any vote given in accordance with the terms of
            an instrument of proxy conforming with clause 17.9(a) shall be valid

            revocation or amendment of the proxy or of any of the Registered
            Noteholder's instructions under which it was executed, so long as no
            intimation in writing of such death, insanity, revocation or
            amendment is received by the Trustee at its registered office or by
            the chairman of the meeting in each case not less than 24 hours
            before the commencement of the meeting or adjourned meeting at which
            the proxy is used.

      17.10 Corporate representatives

      A person authorised under sections 249(3)-(6) of the Corporations Law by a

      is revoked by the body corporate concerned, be entitled to exercise the
      same powers on behalf of that body corporate as that body corporate could
      exercise if it were an individual Registered Noteholder 
- --------------------------------------------------------------------------------

      Noteholder. The Trustee, the Trust Manager and any officer of the Trustee
      and the Trust Manager may be appointed a Representative.

                  have no obligation to any Offshore Note Owners;

            (iii) to the extent that the provisions of this clause conflict with
                  any other provisions of this deed, the provisions of this
                  clause shall prevail;

                  evidencing a specific percentage of all Invested Amounts of
                  all Offshore Notes, the Clearing Agency shall be deemed to
                  represent such percentage only to the extent that it has
                  received instructions to such effect from Offshore Note Owners
                  and/or Clearing Agency Participants owning or representing,
                  respectively, such required percentage of the beneficial
                  interest in the Offshore Notes and has delivered such
                  instructions to the Principal Paying Agent.

3.3   Definitive Notes

            discharge its responsibilities with respect to the Offshore Notes or
            the Clearing Agency or its successor and the Trust Manager is unable
            to locate a qualified successor;

      (b)   the Trustee, at the direction of the Trust Manager (at the Trust
            Manager's option) advises the Principal Paying Agent in writing that
            the book-entry system through the Clearing Agency is or is to be
            terminated; or

      (c)   after the occurrence of an Event of Default, the Offshore Note
            Owners representing beneficial interests aggregating to at least a
            majority of the aggregate Invested Amount of a Class of Offshore
            Notes advise the Trustee through the Clearing Agency in writing that
            the continuation of a book entry system through the Clearing Agency
            is no longer in the best interests of the Offshore Note Owners of
            such Class of Offshore Notes,

      then the Principal Paying Agent shall notify all of the appropriate
      Offshore Note Owners and the Trustee of the occurrence of any such event
      and of the availability of Definitive Notes to such Offshore Note Owners
      requesting the same. Upon the surrender of the Book-Entry Notes to the
      Trustee by the Clearing Agency, and the delivery by the Clearing Agency of

      execute and authenticate the Definitive Notes in accordance with the
      instructions of the Clearing Agency.

      by the Authorised Signatories executing such Definitive Notes, as
      evidenced by their execution of such Definitive Notes.

      in delivery of such instructions and may conclusively rely on, and shall
      be protected in relying on, such instructions.

3.4   Stamp and Other Taxes

            enforce the provisions of the Offshore Notes or the Transaction

3.5   Indemnity for non-issue

      If the Trustee is required to issue, or procure the issue of, Definitive
      Notes following an event specified in clause 3.3 but fails to do so within

      with clause 3.3(e) then the Trustee shall indemnify the Note Trustee, the
      Offshore Noteholders and Offshore Note Owners, and keep them indemnified,
      against any loss or damage incurred by any of them if the amount received
      by the Note Trustee, the Offshore Noteholders or Offshore Note Owners is
      less than the amount that would have been received had Definitive Notes
      been issued. If and for so long as the Trustee discharges its obligations
      under this indemnity, the breach by the Trustee of the provisions of
      clause 3.3 shall be deemed to be cured. The Trust Manager must promptly

      Offshore Note became due and repayable in accordance with the provisions
      of Class A Condition 4 (in the case of Class A Notes), and Class B
      Condition 4 (in the case of Class B Notes) except that no notices need be
      given to Offshore Noteholders, in relation to that interest.

6.4   Restrictions on enforcement

      (a)   If any of the Class A Notes remain outstanding and are due and
            payable otherwise than by reason of a default in payment of any
            amount due on the Class A Notes, the Note Trustee must not vote
            under the Security Trust Deed to, or otherwise direct the Security
            Trustee to, dispose of the Mortgaged Property unless either:

            (i)   a sufficient amount would be realised to discharge in full all
                  amounts owing to the Class A Noteholders and any other amounts
                  payable by the Trustee ranking in priority to or pari passu
                  with the Class A Notes; or

            (ii)  the Note Trustee is of the opinion, reached after considering
                  at any time and from time to time the advice of a merchant
                  bank or other financial adviser selected by the Note Trustee,
                  that the cash flow receivable by the Trustee (or the Security
                  Trustee under the Security Trust Deed) will not (or that there
                  is a significant risk that it will not) be sufficient, having
                  regard to any other relevant actual, contingent or prospective
                  liabilities of the Trustee, to discharge in full in due course
                  all the amounts referred to in paragraph (i).

      (b)   If all Class A Notes have been redeemed in full but while any of the
            Class B Notes remain outstanding and are due and payable otherwise
            than by reason of a default in payment of any amount due on the
            Class B Notes, the Note Trustee must not vote under the Security
            Trust Deed to, or otherwise direct the Security Trustee to, dispose
            of the Mortgaged Property unless either:

            (i)   a sufficient amount would be realised to discharge in full all
                  amounts owing to the Class B Noteholders and any other amounts
                  payable by the Trustee ranking in priority thereto or pari
                  passu with the Class B Notes; or

            (ii)  the Note Trustee is of the opinion, reached after considering
                  at any time and from time to time the advice of a merchant
                  bank or other financial

                  adviser selected by the Note Trustee, that the cash flow
                  prospectively receivable by the Trustee (or the Security
                  Trustee under the Security Trust Deed) will not (or that there
                  is a significant risk that it will not) be sufficient, having
                  regard to any other relevant actual, contingent or prospective
                  liabilities of the Trustee, to discharge in full in due course
                  all amounts referred to in paragraph (i).

      (c)   Neither the Note Trustee nor the Security Trustee will be liable for
            any decline in the value, nor any loss realised upon any sale or
            other dispositions made under the Security Trust Deed, of any
            Mortgaged Property or any other property which is charged to the
            Security Trustee by any other person in respect of or relating to
            the obligations of the Trustee or any third party in respect of the
            Trustee or the Offshore Notes or relating in any way to the
            Mortgaged Property. Without limitation, neither the Note Trustee nor
            the Security Trustee shall be liable for any such decline or loss
            directly or indirectly arising from its acting, or failing to act,
            as a consequence of an opinion reached by it in good faith based on
            advice received by it in accordance with paragraph (a) or (b).

7.    PROCEEDINGS

7.1   Acting only on direction

      (a)   Subject to paragraph (b), the Note Trustee shall not be bound to
            vote under the Security Trust Deed, or otherwise direct the Security
            Trustee under the Security Trust Deed, or take any proceedings,
            actions or steps under, or any other proceedings pursuant to or in
            connection with, the Security Trust Deed, this deed, or any Offshore
            Notes, unless directed or requested to do so in writing by holders
            of at least 75% of the aggregate Invested Amount of Class A Notes or
            the Class B Notes, as appropriate and then only if the Note Trustee
            is indemnified to its satisfaction against all action, proceedings,
            claims and demands to which it may render itself liable and all
            costs, charges, damages and expenses which it may incur by so doing;
            or

      (b)   So long as any of the Class A Notes remains outstanding, the Note
            Trustee shall not, and shall not be bound to, act at the request or
            direction of the Class B Noteholders under paragraph (a) unless:

            (i)   so to do would not in its opinion be materially prejudicial to
                  the interests of the Class A Noteholders; or

            (ii)  the relevant action is sanctioned by holders of at least 75%
                  of the aggregate Invested Amount of the Class A Notes or the
                  Class B Notes, as appropriate; or

            (iii) in the case of giving notice pursuant to Class B Condition 10,
                  the Class A Notes are all then repayable in full.

      (c)   If the Note Trustee is directed or requested to take any
            proceedings, actions or steps under this clause, it shall not be
            liable in respect of the time, method, or place of conducting any
            proceeding or in exercising any trust or power conferred on it under
            this deed.

7.2   Security Trustee acting

      entitled to proceed directly

      against the Trustee to enforce the performance of any of the provisions of
      the Security Trust Deed, the Offshore Notes (including the Conditions).

7.3   Note Trustee alone entitled to act

      Only  the Note Trustee may:

      (a)   direct the Security Trustee to enforce or otherwise; or

      (b)   enforce the provisions of this deed, the Offshore Notes (including
            the Conditions),

      and no Offshore Noteholder or is entitled to take any of the above actions
      or to proceed directly against the Trustee to enforce the performance of
      any of the provisions of this deed the Offshore Notes (including the
      Conditions).

7.4   Available amounts

      For the purpose of Condition 5(n) the Note Trustee shall not be satisfied
      that the Trustee will be in a position to discharge the liabilities
      referred in those Conditions unless, either:

      (a)   the Trustee will have available to it sufficient cash in the
            Collection Account and sufficient Authorised Investments which will
            mature on or before the relevant Payment Date after making any other
            payments or provisions having priority in order of application under
            the applicable provisions of the Security Trust Deed; or

      (b)   the Trustee has entered into a legally binding contract with an
            entity either whose long term unsecured and unguaranteed debt is
            rated AA- by S&P and AA- by Fitch (and, where the obligations relate
            to Class A Notes Aa3 by Moody's) or whose short term unsecured and
            unguaranteed debt securities are rated A-1 by S&P and F-1 by Fitch
            (and, where the obligations relate to Class A Notes P-1 by Moody's)
            to provide sufficient cash on or before the relevant Payment Date to
            enable the Trustee to discharge the relevant liabilities.

7.5   Conflict of interests

      The Note Trustee shall, with respect to all the powers, trusts,
      authorities, duties and discretions vested in it by the Transaction
      Documents, except where expressly provided otherwise, have regard to the
      interests of the Class A Noteholders and the Class B Noteholders subject
      to the proviso in the following sentence. If the Note Trustee is required
      by the Transaction Documents or Notes to have regard to the interests of
      the Class A Noteholders and the Class B Noteholders and where, in the
      opinion of the Note Trustee, there is a conflict between the interests of
      the Class A Noteholders and the interests of the Class B Noteholders, the
      Note Trustee shall have regard only to the interests of the Class A
      Noteholders despite anything to the contrary in the Transaction Documents.
      In such an event, the Class B Noteholders shall have no claim against the
      Note Trustee for doing so.

8.    NOTICE OF PAYMENT

      The Note Trustee shall give notice to the relevant Offshore Noteholders in
      accordance with the relevant Condition 12 of the day fixed for any payment
      to them of amounts received by the Note Trustee under clause 16 of the
      Security Trust Deed. Those payments may be made in accordance with
      Condition 6 as appropriate (in the case of Definitive Notes) or in the
      name of the nominee of the Common Depositary by wire transfer in
      immediately available funds to an account designated by such nominee to
      the order of the registered holder of the Offshore Note (in the case of
      any Book-Entry

      Trustee.

      invested by the Note Trustee, may be invested in the name or under the
      control of the Note Trustee in any Authorised Investments and the Note
      Trustee may at any time or times vary any Authorised Investments into
      other Authorised Investments and shall not be responsible for any loss due
      to depreciation in value or otherwise resulting from any Authorised
      Investments made by it.

10.   PARTIAL PAYMENTS

      produced to the Note Trustee or the Paying Agent by or through whom such
      payment is made and the Note Trustee shall or shall cause the Paying Agent
      to enface on the Definitive Note a memorandum of the amount and the date
      of payment, but the Note Trustee may in any particular case dispense with
      that production and enfacement upon an indemnity being given to the Note
      Trustee by the recipient of the payment as the Note Trustee considers
      sufficient.

11.   COVENANTS BY THE TRUSTEE AND TRUST MANAGER

                  of its officers who are responsible for the administration of
                  the Trust, it becomes actually aware of the occurrence of an
                  Event of Default, Trustee's Default, Servicer Transfer Event,
                  Title Perfection Event or Trust Manager's Default including

                  Event, Title Perfection Event or Trust Manager's Default (as
                  the case may be).

            (ii)  The Trustee will confirm to the Note Trustee in writing, on
                  each anniversary of this deed:

                  (A)   whether or not any Event of Default is subsisting of
                        which it is actually aware; and

                  (B)   any other matter which is required to be notified to the
                        Note Trustee under the Transaction Documents and which
                        has not previously been so notified.

      (e)   (Listing) It will use its best endeavours to:

            (i)   obtain and maintain the listing of the Offshore Notes on the
                  Stock Exchange (including compliance with the continuing
                  obligations applicable to the Trustee by virtue of the
                  admission of the Offshore Notes to the Official List of the
                  Stock Exchange) or, if it is unable to do so having used best
                  endeavours, use best endeavours to obtain and maintain a
                  quotation or listing of the Offshore Notes on any other stock
                  exchange or exchanges or securities market or markets as the
                  Trust Manager (with the prior written approval of the Note
                  Trustee, that approval not to be unreasonably withheld or
                  delayed) decides and following that quotation or listing enter
                  into a deed supplemental to this Trust Deed to effect such
                  consequential amendments to this deed necessary to comply with
                  the requirements of any such stock exchange or securities
                  market; and

            (ii)  procure that there will at all times be furnished to the Stock
                  Exchange (or to any other relevant stock exchange or
                  securities market) any information which the Stock Exchange
                  or, as the case may be, any other such stock exchange or
                  securities market, may require to be furnished in accordance
                  with its requirements.

      (f)   (Maintenance of Office or Agency) The Trustee will maintain in the

            the Trustee in respect of the Offshore Notes and this deed may be
            served. The Trustee hereby initially appoints the Principal Paying
            Agent to serve as its agent for the foregoing purposes. The
            Principal Paying Agent shall act solely for and as agent of the
            Trustee and shall not have any obligations towards or relationship
            or agency or trust with any other person in respect of its
            appointment under this sub-paragraph (f). The Trustee will give
            prompt written notice to the Note Trustee of the location, and of
            any change in the location, of any such office or agency. If at any
            time the Trustee shall fail to maintain any such office or agency or
            shall fail to furnish the Note Trustee with the address thereof,
            such surrenders, notices and demands may be made or served at the
            Corporate Trust Office, and the Trustee hereby appoints the Note
            Trustee as its agent to receive all such surrenders, notices and
            demands.

      (g)   (Agent Bank) It will procure that, so long as any of the Offshore

                  Documents throughout the relevant year, or, if there has been
                  a default in the compliance of any such condition or covenant,
                  specifying each such default known to the Signatory of the
                  nature and status of the default.

            For the purposes of this clause 11.2(j) compliance shall be
            determined without regard to any period of grace or requirement of

            and reciting the details of such action, or stating that in the
            opinion of such counsel no such action is necessary to make such

            June 1999 the Trustee shall furnish to the Note Trustee an Opinion
            of Counsel (who may be of counsel for the Trustee) either stating
            that in the opinion of such counsel such action has been taken with

      If the Note Trustee gives a notice under the relevant Condition 10 or it
      undertakes duties which it considers expedient or necessary under this
      deed, or which the Trustee requests it to undertake and which duties the
      Note Trustee, the Trust Manager and the Trustee agree to be of an
      exceptional nature or otherwise outside the scope of the normal duties of
      the Note Trustee under this deed, the Trustee shall pay to the Note
      Trustee any additional remuneration as they agree.

12.3  Costs, expenses

            undertaking its duties under the Transaction Documents and in
            connection with any legal proceedings brought by the Note Trustee to

            Note Trustee shall not be reimbursed for any overhead or general
            operating expenses incurred by the Note Trustee.

      (b)   Without prejudice to the right of indemnity by law given to

      Trustee on the next Payment Date in the order set out in the Series Notice

      rate of LIBOR from the due date. Any amount payable shall carry interest
      at that rate from the due date to the date of actual payment.

12.5  Continuing obligation

      Unless otherwise specifically stated in any discharge relating to this
      deed the provisions of this clause shall continue in full force and effect

13.   NOTE TRUSTEE

13.1  Preferential Collection of Claims Against Trustee

      The Note Trustee shall comply with section 311(a) of the TIA, excluding
      any creditor relationship listed in section 311(b) of the TIA. A Note
      Trustee who has resigned or been removed shall be subject to section
      311(a) of TIA to the extent required by the TIA.

13.2  Duties of Note Trustee

      (a)   If an Event of Default has occurred and is subsisting, of which a
            Responsible Officer of the Note Trustee has actual knowledge, the
            Note Trustee shall exercise the rights and powers vested in it by
            this deed and use the same degree of care and skill in their
            exercise as a prudent person would exercise or use under the
            circumstances in the conduct of such person's own affairs.

      (b)   Except while an Event of Default subsists:

            (i)   the Note Trustee undertakes to perform such duties and only
                  such duties as are specifically set forth in this deed and no
                  implied covenants or obligations shall be read into this deed
                  against the Note Trustee; and

            (ii)  in the absence of bad faith on its part, the Note Trustee may
                  conclusively rely, as to the truth of the statements and the
                  correctness of the opinions expressed therein, upon
                  certificates or opinions furnished to the Note Trustee and
                  conforming to the requirements of this deed; however, the Note
                  Trustee shall examine the certificates and opinions to
                  determine whether or not they conform to the requirements of
                  this deed.

      (c)   The Note Trustee may not be relieved from liability for its own
            negligent action, its own negligent failure to act or its own wilful
            misconduct, except that:

            (i)   this paragraph does not limit the effect of paragraph (a) of
                  this clause; and

            (ii   the Note Trustee shall not be liable for any error of judgment
                  made in good faith by a Responsible Officer unless it is
                  proved that the Note Trustee was negligent in ascertaining the
                  pertinent facts.

      (d)   Section 315(d)(3) of the TIA is expressly excluded by this deed.

13.3  Notice of Defaults

      (a)   If an Event of Default occurs and is subsisting and the Note Trustee
            is actually aware of that Event of Default, the Note Trustee shall
            mail to each Offshore Noteholder notice of the Event of Default
            within 90 days after becoming so aware.

      (b)   Except in the case of a default in payment of principal of or
            interest on any Offshore Note (including payments pursuant to the
            mandatory redemption provisions of that Offshore Note), the Note
            Trustee may withhold the notice referred to in paragraph (a) if and
            so long as the board of directors, the executive committee or a
            trust committee of its directors in good faith determines that
            withholding the notice is in the interest of Offshore Noteholders.

13.4  Rights of Note Trustee

      (a)   The Note Trustee may conclusively rely on any document believed by
            it to be genuine and to have been signed or presented by the proper
            person. The Note Trustee need not investigate any fact or matter
            stated in the document.

      (b)   Before the Note Trustee acts or refrains from acting, it may require
            an Officer's Certificate or an Opinion of Counsel. The Note Trustee
            shall not be liable for any action it takes, suffers or omits to
            take in good faith in reliance on the Officer's Certificate or
            Opinion of Counsel.

      (c)   No provision of this deed shall require the Note Trustee to expend
            or risk its own funds or otherwise incur financial liability in the
            performance of any of its duties hereunder or in the exercise of any
            of its rights or powers, if it shall have reasonable grounds to
            believe that repayment of such funds or indemnity satisfactory to it
            against such risk or liability is not assured to it.

      (d)   The Note Trustee shall not be responsible for and makes no
            representation as to the validity or adequacy of this deed or the
            Offshore Notes, shall not be accountable for the Trustee's use of
            the proceeds from the Offshore Notes, and shall not be responsible
            for any statement of the Trustee in this deed or in any document
            issued in connection with the sale of the Offshore Notes or in the
            Offshore Notes.

      (e)   The Note Trustee may in relation to this deed act on the advice or
            opinion of or any information obtained from any lawyer, valuer,
            accountant, banker, broker, credit-rating agency, lead manager or
            other expert whether obtained by the Trustee, the Note Trustee, the
            Trust Manager, the Servicer or otherwise.

      (f)   Any advice, opinion or information may be sent or obtained by
            letter, telex, telegram, facsimile transmission or cable and the
            Note Trustee shall not be liable for acting on any advice, opinion
            or information purporting to be conveyed by any such letter, telex,
            telegram, facsimile transmission or cable although the same shall
            contain some error or shall not be authentic.

      (g)   The Note Trustee may call for and shall be at liberty to accept as
            sufficient evidence of any fact or matter or the expediency of any
            transaction or thing a certificate signed by an Authorised Signatory
            of the Trustee or the Trust Manager (as the case may be) and the
            Note Trustee shall not be bound in any such case to call for further
            evidence or be responsible for any loss that may be occasioned by
            the Note Trustee acting on that certificate.

      (h)   The Note Trustee is at liberty to hold or to place this deed and any
            other documents relating to this deed in any part of the world
            (other than Australia) with any banker or banking company or company
            whose business includes undertaking the safe custody of documents or
            lawyer or firm of lawyers reasonably considered by the Note Trustee
            to be of good repute and neither the Note Trustee nor the Security
            Trustee shall be responsible for or required to insure against any
            loss incurred in connection with any such deposit and may pay all
            sums required to be paid on account of or in respect of any such
            deposit.

      (i)   The Note Trustee shall not be responsible for the application of the
            proceeds of the issue of any of the Offshore Notes by the Trustee or
            any moneys borrowed by the Trustee under any Transaction Document or
            the exchange of any Book-Entry Note for any other Book-Entry Note or
            Definitive Note, as the case may be.

      (j)   The Note Trustee shall not be bound to give notice to any person of
            the execution of this deed or any of the Transaction Documents or
            any transaction contemplated hereby or thereby or to take any steps
            to ascertain whether any Event of Default has happened and, until it
            has actual knowledge or express notice to the contrary, the Note
            Trustee is entitled to assume that no Event of Default has happened
            and that the Trustee and each other party to any Relevant Document
            is observing and performing all the obligations on its part
            contained in the Offshore Notes and under this deed or, as the case
            may be, the Security Trust Deed or any other Transaction Document to
            which it is a party.

      (k)   Save as expressly otherwise provided in this deed or the Transaction
            Documents, the Note Trustee shall have absolute and uncontrolled
            discretion as to the exercise of the discretions vested in the Note
            Trustee by this deed and the Transaction Documents (the exercise of
            which as between the Note Trustee and the Offshore Noteholders and
            Couponholders) shall be conclusive and binding on the Offshore
            Noteholders and Couponholders but whenever the Note Trustee is under
            the provisions of this deed or the Transaction Documents bound to
            act at the request or direction of the Offshore Noteholders, or any
            of them, the Note Trustee shall nevertheless not be so bound unless
            first indemnified to its satisfaction against all actions,
            proceedings, claims and demands to which it may render itself liable
            and all costs, charges, damages, expenses and liabilities which it
            may incur by so doing.

      (l)   Any consent or approval given by the Note Trustee for the purpose of
            this deed, the Conditions and any Transaction Document may be given
            on any terms and subject to any conditions as the Note Trustee
            thinks fit and despite anything to the contrary contained in this
            deed, any Transaction Document or the Conditions may be given
            retrospectively.

      (m)   The Note Trustee shall not (unless and to the extent ordered so to
            do by a court of competent jurisdiction) be required to disclose to
            any Offshore Noteholder or any Mortgagee, any confidential
            financial, price sensitive or other information made available to
            the Note Trustee by the Trustee or any other person in connection
            with the trusts of this deed and no Offshore Noteholder shall be
            entitled to take any action to obtain from the Note Trustee any such
            information.

      (n)   Where it is necessary or desirable for any purpose in connection
            with this deed to convert any sum from one currency to another it
            shall (unless otherwise provided by this deed or required by law) be
            converted at the rate or rates, in accordance with the method and as
            at the date for the determination of the rate of exchange, as may be
            agreed by the Note Trustee in consultation with the Trustee and the
            Trust Manager as relevant and any rate, method and date so agreed
            shall be binding on the Trustee, the Offshore Noteholders.

      (o)   The Note Trustee may certify whether or not any of the events set
            out in paragraphs (b) to (e) of the relevant Condition 9 or any
            breach under clause 8 of the Security Trust Deed is in its opinion
            materially prejudicial to the interests of the relevant Offshore
            Noteholders and may certify, in relation to the event set out in
            paragraph (a) of the relevant Condition 9 in relation to any payment
            of interest on the Offshore Notes that the Trustee had, on the due
            date for payment of the amount of interest in question, sufficient
            cash to pay, in accordance with the provisions of the Series Notice
            or the Security Trust Deed, all interest (after payment of all sums
            which are permitted under the Series Notice or the Security Trust
            Deed to be paid in priority to or pari passu with them) and that
            certificate shall be conclusive and binding upon the Trustee, the
            Offshore Noteholders. The Note Trustee shall have no liability to
            the Trustee, any Offshore Noteholder or any other person

            in relation to any such certificate or in relation to any delay or
            omission in providing certificate. In giving any certificate
            relating to paragraph (a) of the relevant Condition 9, the Note
            Trustee may rely on any determination made by any independent
            accountants of recognised standing in Australia and any such
            determination shall be conclusive and binding on the Trustee and the
            Offshore Noteholders.

      (p)   The Note Trustee shall not be bound to take any steps to ascertain
            whether any event, condition or act, the happening of which would
            cause a right or remedy to become exercisable by the Note Trustee
            under this deed or by the Trustee under any of the Transaction
            Documents has happened or to monitor or supervise the observance and
            performance by the Trustee or any of the other parties thereto of
            their respective obligations thereunder and, until it shall have
            actual knowledge or express notice to the contrary the Note Trustee
            shall be entitled to assume that no such event, condition or act has
            happened and that the Trustee and each of the other parties thereto
            are observing and performing all their respective obligations
            thereunder.

      (q)   The Note Trustee shall not be responsible for recitals, statements,
            warranties or representations of any party contained in any
            Transaction Document or other document entered into in connection
            with it and shall assume its accuracy and correctness and its
            execution, legality, effectiveness, adequacy, genuineness, validity
            or enforceability or admissibility in evidence of that agreement or
            other document or any security constituted by them, and the Note
            Trustee may accept without enquiry, requisition or objection all
            title as the Trustee may have to any of the Mortgaged Property or as
            any other person may have to any other security charged from time to
            time to the Note Trustee and shall not be bound to investigate or
            make any enquiry in the title of the Trustee to any of the Mortgaged
            Property or the title of any other person to any other security
            charged from time to time to the Note Trustee whether or not any
            default or failure is or was known to the Note Trustee or might be,
            or might have been, discovered upon examination inquiry or
            investigation and whether or not capable of remedy. Notwithstanding
            the generality of the foregoing each Offshore Noteholder is solely
            responsible for making its own independent appraisal of and
            investigation into the financial condition, creditworthiness,
            condition, affairs, status and nature of the Trustee and the Note
            Trustee shall not at any time have any responsibility for the same
            and no Offshore Noteholder or Couponholder shall rely on the Note
            Trustee in that respect.

      (r)   The Note Trustee shall not be liable for any failure, omission or
            defect in or filing or procuring registration or filing of or
            otherwise protecting or perfecting the Security Trust Deed or the
            Mortgaged Property or any other security or failure to call or
            delivery of documents of title to the Mortgaged Property or any
            other security or to require any further assurances in relation to
            any property or assets comprised in the Mortgaged Property or any
            other security.

      (s)   The Note Trustee shall not be obliged (whether or not directed to do
            so by the Offshore Noteholders) to direct the Security Trustee to
            perfect legal title to any Purchased Receivable Security if, in the
            opinion of the Note Trustee, that perfection would or might result
            in the Note Trustee becoming liable to or incurring any obligation
            to any Borrower under a Purchased Receivable Security and, in its
            opinion, there is or would be insufficient cash to discharge, in
            accordance with the provisions of the Security Trust Deed, that
            liability or obligations as and when they arise. Notwithstanding the
            generality of the foregoing, the Note Trustee shall have no
            responsibility or liability for the payment of any fees for the
            registration of any Receivable Security in Australia or for any
            related legal, administrative or other fees, costs and expenses
            (including, but not limited to, any proper disbursements and any
            value added tax).

      (t)   The Note Trustee shall, as regards all the powers, trusts,
            authorities, duties and discretions vested in it by this deed, the
            Transaction Documents or the Offshore Notes (including the
            Conditions), except where expressly provided otherwise have regard
            to the interests of the Class A Noteholders and the Class B
            Noteholders, except that where the Note Trustee is required by this
            deed, the Transaction Documents or the Offshore Notes (including the
            Conditions) to have regard to the interests of the Class A
            Noteholders and the Class B Noteholders and where, in the opinion of
            the Note Trustee, there is a conflict between the interests of the
            Class A Noteholders and the interests of the Class B Noteholders the
            Note Trustee shall, despite anything to the contrary contained in
            this deed, the Transaction Documents or the Offshore Notes
            (including the Conditions), have regard only to the interests of the
            Class A Noteholders and the Class B Noteholders who shall have no
            claim against the Note Trustee for so doing.

      (u)   Without prejudice to the provisions of any Transaction Document, the
            Note Trustee shall not be under any obligation to insure any of the
            Mortgaged Property (or any other property) or any deeds or documents
            of title or other evidence relating to that property and shall not
            be responsible for any loss, expense or liability which may be
            suffered as a result of the lack of or inadequacy of any that
            insurance.

      (v)   The Note Trustee shall not be responsible for any loss, expense or
            liability occasioned to the Mortgaged Property or any other property
            or in respect of all or any of the moneys which may stand to the
            credit of the Collection Accounts from time to time however caused
            (including any bank, broker, depositary, warehouseman or other
            intermediary or any clearing system or its operator acting in
            accordance with or contrary to the terms of any of the Transaction
            Documents or otherwise), unless that loss is occasioned by the
            wilful neglect or misconduct or fraud of the Note Trustee.

      (w)   The Note Trustee has no responsibility whatsoever to the Trustee or
            any Offshore Noteholder as regards any deficiency or additional
            payment, as the case may be, which might arise because the Note
            Trustee or the Trustee is subject to any Tax in respect of the
            Mortgaged Property, the Security Trust Deed or any other security or
            any income or any proceeds from them.

      (x)   No provision of this deed requires the Note Trustee to do anything
            which may be illegal or contrary to applicable law or regulation or
            expend or risk its own funds or otherwise incur any financial
            liability in the performance of any of its duties, or in the
            exercise of any of its rights or powers, if it has reasonable
            grounds to believe that repayment of those funds or adequate

            Offshore Notes by reason of any variation in the rates of exchange
            between those used for the purposes of calculating the amount due
            under a judgment or order in respect of that payment, which amount
            is expressed in a currency other than US$, and under which the Note
            Trustee, the Offshore Noteholders do not have an option to have that
            judgment or order expressed in US$, and those prevailing at the date
            of actual payment by the Trustee; and

                  of the US$ amounts due or contingently due under this deed
                  (other than this clause) or in respect of the relevant
                  Offshore Notes is calculated for the purposes of any
                  bankruptcy, insolvency or liquidation of the Trustee; and

            (ii)  the final date for ascertaining the amount of claims in that
                  bankruptcy, insolvency or liquidation provided that in that
                  bankruptcy, insolvency or liquidation claims are required to
                  be made in a currency other than US$.

                   The amount of that deficiency shall not be reduced by any
                   variation in rates of exchange occurring between that final
                   date and the date of any distribution of assets in connection
                   with that bankruptcy, insolvency or liquidation.

      (c)   The indemnities in this clause are obligations of the Trustee
            separate and independent from its obligations under the Offshore
            Notes and apply irrespective of any time or indulgence granted by
            the Note Trustee or the Offshore Noteholders from time to time and
            shall continue in full force and effect despite the judgment or
            filing of any proof or proofs in any bankruptcy, insolvency or
            liquidation of the Trustee for a liquidated sum or sums in respect
            of amounts due under this deed (other than this clause) or the
            Offshore Notes. Any deficiency will constitute a loss suffered by

29.   LIMITED RECOURSE

29.1  General

      Clause 33 of the Master Trust Deed applies to the obligations and
      liabilities of the Trustee and the Trust Manager under this deed.

29.2  Liability of Trustee limited to its right to indemnity

      (a)   This deed applies to the Trustee only in its capacity as trustee of
            the Trust and in no other capacity. A liability arising under or in
            connection with this deed or the Trust can be enforced against the
            Trustee only to the extent to which it can be satisfied out of
            property of the Trust out of which the Trustee is actually
            indemnified for the liability. This limitation of the Trustee's
            liability applies despite any other provision of this deed and
            extends to all liabilities and obligations of the Trustee in any way
            connected with any representation, warranty, conduct, omission,
            agreement or transaction related to this deed or the Trust.

      (b)   The parties other than the Trustee may not sue the Trustee in any
            capacity other than as trustee of the Trust or seek the appointment
            of a receiver (except under the Security Trust Deed), or a
            liquidator, an administrator or any similar person to the Trustee or
            prove in any liquidation, administration or arrangements of or
            affecting the Trustee.

      (c)   The provisions of this clause 29 shall not apply to any obligation
            or liability of the Trustee to the extent that it is not satisfied
            because under a Transaction Document or by operation of law there is
            a reduction in the extent of the Trustee's indemnification out of
            the Assets of the Trust as a result of the Trustee's fraud,
            negligence or breach of trust.

      (d)   Without affecting any limit or exclusion of liability in relation to
            the duties, powers or obligations under the Transaction Documents of
            any of the Trust Manager, the Servicer, the Note Trustee, the

            reasonably require, of the names and addresses of the Offshore
            Noteholders as of the Record Date immediately preceding that Notice
            Date; and

      (b)   at such other times as the Note Trustee may request in writing,
            within 30 days after receipt by the Trustee of any such request, a
            list of similar form and content as of a date not more than 10 days
            prior to the time such list is furnished,

      provided that so long as:

            reasonably practicable, the names and addresses of the Offshore

            the Note Trustee as provided in clause 31.1 and, so long as it
            continues to act as Note Registrar, the names and addresses of
            Offshore Noteholders received by the Note Trustee in its capacity as
            Note Registrar. The Trustee may destroy any list furnished to it as
            provided in such clause 31.1 upon receipt of a new list so
            furnished.

      (b)   Offshore Noteholders may communicate pursuant to section 312(b) of
            the TIA with other Offshore Noteholders with respect to their rights
            under this Deed or under the Offshore Notes.

      (c)   The Trustee, Note Trustee and Note Registrar shall have the
            protection of section 312(c) of the TIA.

31.3  Reports by Note Trustee

      If required by section 313(a) of the TIA, within 60 days after each 30
      June, beginning with 30 June 1999, the Note Trustee shall mail to each
      Offshore Noteholder and the Trustee as required by section 313(c) of the
      TIA a brief report dated as of such date that complies with section 313(a)
      of the TIA. The Note Trustee also shall comply with section 313(b) of the
      TIA. A copy of each report at the time of its mailing to Offshore
      Noteholders shall be filed by the Note Trustee with the Commission and
      each stock exchange, if any, on which the Offshore Notes are listed. The

31.4  Notices to Offshore Noteholders; Waiver

      Where this deed provides for notice to Offshore Noteholders of any event,

      provided) if in writing and mailed, first-class, postage prepaid to each
      Offshore Noteholder affected by such event, at his or her address as it
      appears on the Note Register, not later than the latest date, and not
      earlier than the earliest date, prescribed for the giving of such notice.
      In any case where notice to Offshore Noteholders is given by mail, neither
      the failure to mail such notice nor any defect in any notice so mailed to
      any particular Offshore Noteholder shall affect the sufficiency of such
      notice with respect to other Offshore Noteholders, and any notice that is
      mailed in the manner herein provided shall conclusively be presumed to
      have been duly given.

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


      Where this deed provides for notice in any manner, such notice may be
      waived in writing by any person entitled to receive such notice, either
      before or after the event, and such waiver shall be the equivalent of such
      notice. Waivers of notice by Offshore Noteholders shall be filed with the
      Note Trustee but such filing shall not be a condition precedent to the
      validity of any action taken in reliance upon such a waiver.

      In case, by reason of the suspension of regular mail services as a result
      of a strike, work stoppage or similar activity, it shall be impractical to
      mail notice of any event to Offshore Noteholders when such notice is
      required to be given pursuant to any provision of this deed, then any
      manner of giving such notice as the Trustee shall direct the Note Trustee
      shall be deemed to be a sufficient giving of such notice.

31.5  Reports by Trustee

      The Trustee shall:

      (a)   file with the Note Trustee, within 15 days after the Trustee is
            required to file the same with the Commission, copies of the annual
            reports and of the information, documents and other reports (or
            copies of such portions of any of the foregoing as the Commission
            may from time to time by rules and regulations prescribe) which the
            Trustee may be required to file with the Commission pursuant to
            section 13 or 15(d) of the Securities Exchange Act of 1934, as
            amended;

      (b)   file with the Note Trustee and the Commission in accordance with
            rules and regulations prescribed from time to time by the Commission
            such additional information, documents and reports with respect to
            compliance by the Trustee with the conditions and covenants of this
            deed as may be required from time to time by such rules and
            regulations; and

      (c)   supply to the Note Trustee (and the Note Trustee shall transmit by
            mail to all Offshore Noteholders described in section 313(c) of the
            TIA) such summaries of any information, documents and reports
            required to be filed by the Trustee pursuant to clauses (a) and (b)
            of this clause 31.5 as may be required by rules and regulations
            prescribed from time to time by the Commission.

            (b)(i)Prior to the deposit of any property or securities with

                  created by the Security Trust Deed, the Trustee shall, in

                  opinion of any signer thereof as to the matters described in

                  Note Trustee an Independent Certificate as to the same matters
                  if the fair value of the property or securities and of all
                  other property or securities deposited or released from the

Book-Entry Note, for so long as this Class A/Class B* Book-Entry Note is
outstanding.

                                MASTER AGREEMENT

                          dated as of __________ 1998

Westpac Banking Corporation         Westpac Securities Administration Limited
(ARBN 007 457 141)                  (ACN 000 049 472) in its capacity as
- ------------------------------ and ---------------------------------------------
                                    trustee of the Series 1998-1G WST Trust
                                    and other parties shown on page 18 of this
                                    agreement

have entered and/or anticipate entering into one or more transactions (each a
"Transaction") that are or will be governed by this Master Agreement, which
includes the schedule (the "Schedule"), and the documents and other confirming
evidence (each a "Confirmation") exchanged between the parties confirming those
Transactions.

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 other provisions of this Master Agreement, the Schedule
will prevail. In the event of any inconsistency between the provisions of any
Confirmation and this Master Agreement (including the Schedule), such
Confirmation will prevail for the purpose of the relevant Transaction.

(c) Single Agreement. All Transactions are entered into in reliance on the fact
that this Master Agreement and all Confirmations form a single agreement between
the parties (collectively referred to as this "Agreement"), and the parties
would not otherwise enter into any Transactions.

2. Obligations

(a) General Conditions.

      (i) Each party will make each payment or delivery specified in each
      Confirmation to be made by it, subject to the other provisions of this
      Agreement.

      (ii) Payments under this Agreement will be made on the due date for value
      on that date in the place of the account specified in the relevant
      Confirmation or otherwise pursuant to this Agreement, in freely
      transferable funds and in the manner customary for payments in the
      required currency. Where settlement is by delivery (that is, other than by
      payment), such delivery will be made for receipt on the due date in the
      manner customary for the relevant obligation unless otherwise specified in
      the relevant Confirmation or elsewhere in this Agreement.

      (iii) Each obligation of each party under Section 2(a)(i) is subject to
      (1) the condition precedent that no Event of Default or Potential Event of
      Default with respect to the other party has occurred and is continuing,
      (2) the condition precedent that no Early Termination Date in respect of
      the relevant Transaction has occurred or been effectively designated and
      (3) each other applicable condition precedent specified in this Agreement.


<PAGE>

(b) Change of Account. Either party may change its account for receiving a
payment or delivery by giving notice to the other party at least five Local
Business Days prior to the scheduled date for the payment or delivery to which
such change applies unless such other party gives timely notice of a reasonable
objection to such change.

(c) Netting. If on any date amounts would otherwise be payable: --

      (i) in the same currency; and

      (ii) in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to make
payment or any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount
will be determined in respect of all amounts payable on the same date in the
same currency in respect of such Transactions, regardless of whether such
amounts are payable in respect of the same Transaction. The election may be made
in the Schedule or a Confirmation by specifying that subparagraph (ii) above
will not apply to the Transactions identified as being subject to the election,
together with the starting date (in which case subparagraph (ii) above will not,
or will cease to, apply to such Transactions from such date). This election may
be made separately for different groups of Transactions and will apply
separately to each pairing of Offices through which the parties make and receive
payments or deliveries.

(d) Deduction or Withholding for Tax.

      (i) Gross-Up. All payments under this Agreement will be made without any
      deduction or withholding for or on account of any Tax unless such
      deduction or withholding is required by any applicable law, as modified by
      the practice of any relevant governmental revenue authority, then in
      effect. If a party is so required to deduct or withhold, then that party
      ("X") will: --

            (1) promptly notify the other party ("Y") of such requirement;

            (2) pay to the relevant authorities the full amount required to be
            deducted or withheld (including the full amount required to be
            deducted or withheld from any additional amount paid by X to Y under
            this Section 2(d)) promptly upon the earlier of determining that
            such deduction or withholding is required or receiving notice that
            such amount has been assessed against Y;

            (3) promptly forward to Y an official receipt (or a certified copy),
            or other documentation reasonably acceptable to Y, evidencing such
            payment to such authorities; and

            (4) if such Tax is an Identifiable Tax, pay to Y, in addition to the
            payment to which Y is otherwise entitled under this Agreement, such
            additional amount as is necessary to ensure that the net amount
            actually received by Y (free and clear of Indemnifiable Taxes,
            whether assessed against X or Y) will equal the full amount Y would
            have received had no such deduction or withholding been required.
            However, X will not be required to pay any additional amount to Y to
            the extent that it would not be required to be paid but for: --

                  (A) the failure by Y to comply with or perform any agreement
                  contained in Section 4(a)(i), 4(a)(iii) or 4(d); or

                  (B) the failure of a representation made by Y pursuant to
                  Section 3(f) to be accurate and true unless such failure would
                  not have occurred but for (I) any action taken by a taxing
                  authority, or brought in a court of competent jurisdiction, on
                  or after the date on which a Transaction is entered into
                  (regardless of whether such action is taken or brought with
                  respect to a party to this Agreement) or (II) a Change in Tax
                  Law.


                                       2
<PAGE>

      (ii) Liability. if: --

            (1) X is required by any applicable law, as modified by the practice
            of any relevant governmental revenue authority, to make any
            deduction or withholding in respect of which X would not be required
            to pay an additional amount to Y under Section 2(d)(i)(4);

            (2) X does not so deduct or withhold; and
 
            (3) a liability resulting from such Tax is assessed directly against
            X,

      then, except to the extent Y has satisfied or then satisfies the liability
      resulting from such Tax, Y will promptly pay to X the amount of such
      liability (including any related liability for interest, but including any
      related liability for penalties only if Y has failed to comply with or
      perform any agreement contained in Section 4(a)(i), 4(a)(iii) or 4(d)).

(e) Default Interest; Other Amounts. Prior to the occurrence or effective
designation of an Early Termination Date in respect of the relevant Transaction,
a party that defaults in the performance of any payment obligation will, to the
extent permitted by law and subject to Section 6(c), be required to pay interest
(before as well as after judgement) on the overdue amount to the other party on
demand in the same currency as such overdue amount, for the period from (and
including) the original due date for payment to (but excluding) the date of
actual payment, at the Default Rate. Such interest will be calculated on the
basis of daily compounding and the actual number of days elapsed. If, prior to
the occurrence or effective designation of an Early Termination Date in respect
of the relevant Transaction, a party defaults in the performance of any
obligation required to be settled by delivery, it will compensate the other
party on demand if and to the extent provided for in the relevant Confirmation
or elsewhere in this Agreement.

3. Representations

Each party represents to the other party (which representations will be deemed
to be repeated by each party on each date on which a Transaction is entered into
and, in the case of the representations in Section 3(f), at all times until the
termination of this Agreement) that: --

(a) Basic Representations.

      action to authorise such execution, delivery and performance;

      (iii) No Violation or Conflict. Such execution, delivery and performance

      complied with; and

      (v) Obligations Binding. Its obligations under this Agreement and any
      Credit Support Document to which it is a party constitute its legal, valid
      and binding obligations, enforceable in accordance with their respective
      terms (subject to applicable bankruptcy, reorganisation, insolvency,
      moratorium or similar laws affecting creditors' rights generally and
      subject, as to enforceability, to equitable principles of general
      application (regardless of whether enforcement is sought in a proceeding

      deduction or withholding for or on account of any Tax or with such
      deduction or withholding at a reduced rate (so long as the completion,

located ("Stamp Tax Jurisdiction") and will indemnify the other party against
any Stamp Tax levied or imposed upon the other part or in respect of the other

      (i) Illegality. Due to the adoption of, or any change in, any applicable
      law after the date on which a Transaction is entered into, or due to the
      promulgation of, or any change in, the interpretation by any court,
      tribunal or regulatory authority with competent jurisdiction of any
      applicable law after such date, it becomes unlawful (other than as a
      result of a breach by the party of Section 4(b)) for such party (which
      will be the Affected Party): --

            (1) to perform any absolute or contingent obligation to make a
            payment or delivery or to receive a payment or delivery in respect
            of such Transaction or to comply with any other material provision
            of this Agreement relating to such Transaction; or

            (2) to perform, or for any Credit Support Provider of such party to
            perform, any contingent or other obligation which the party (or such
            Credit Support Provider) has under any Credit Support Document
            relating to such Transaction;

      (ii) Tax Event. Due to (x) any action taken by a taxing authority, or
      brought in a court of competent jurisdiction, on or after the date on
      which a Transaction is entered into (regardless of whether such action is
      taken or brought with respect to a party to this Agreement) or (y) a
      Change in Tax Law, the party (which will be the Affected Party) will, or
      there is a substantial likelihood that it will, on the next succeeding
      Scheduled Payment Date (1) be required to pay to the other party an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount is required to be
      deducted or withheld for or on account of a Tax (except in respect of
      interest under Section 2(e), 6(d)(ii) or 6(e)) and no additional amount is
      required to be paid in respect of such Tax under Section 2(d)(i)(4) (other
      than by reason of Section 2(d)(i)(4)(A) or (B));

      (iii) Tax Event Upon Merger. The party (the "Burdened Party") on the next
      succeeding Scheduled Payment Date will either (1) be required to pay an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount has been deducted or
      withheld for or on account of any Indemnifiable Tax in respect of which
      the other party is not required to pay an additional amount (other than by
      reason of Section 2(d)(i)(4)(A) or (B)), in either case as a result of a
      party consolidating or amalgamating with, or merging with or into, or
      transferring all or substantially all its assets to, another entity (which
      will be the Affected Party) where such action does not constitute an event
      described in Section 5(a)(viii);

      (iv) Credit Event Upon Merger. If "Credit Event Upon Merger" is specified
      in the Schedule as applying to the party, such party ("X"), any Credit
      Support Provider of X or any applicable Specified Entity of X consolidates
      or amalgamates with, or merges with or into, or transfers all or
      substantially all its assets to, another entity and such action does not
      constitute an event described in Section 5(a)(viii) but the
      creditworthiness of the resulting, surviving or transferee entity is
      materially weaker than that of X, such Credit Support Provider or such
      Specified Entity, as the case may be, immediately prior to such action
      (and, in such event, X or its successor or transferee, as appropriate,
      will be the Affected Party); or

      (v) Additional Termination Event. If any "Additional Termination Event" is
      specified in the Schedule or any Confirmation as applying, the occurrence
      of such event (and, in such event, the Affected Party or Affected Parties
      shall be as specified for such Additional Termination Event in the
      Schedule or such Confirmation).

(c) Event of Default and Illegality. If an event or circumstance which would
otherwise constitute or give rise to an Event of Default also constitutes an
Illegality, it will be treated as an Illegality and will not constitute an Event
of Default.


                                       7

6. Early Termination

(a) Right to Terminate Following Event of Default. If at any time an Event of
Default with respect to a party (the "Defaulting Party") has occurred and is
then continuing, the other party (the "Non-defaulting Party") may, by not more
than 20 days notice to the Defaulting Party specifying the relevant Event of
Default designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however,
"Automatic Early Termination" is specified in the Schedule as applying to a
party, then an Early Termination Date in respect of all outstanding Transactions
will occur immediately upon the occurrence with respect to such party of an
Event of Default specified in Section 5(a)(vii)(1), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the
institution of the relevant proceeding or the presentation of the relevant
petition upon the occurrence with respect to such party of an Event of Default
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b) Right to Terminate Following Termination Event.

      (i) Notice. If a Termination Event occurs, an Affected Party will,
      promptly upon becoming aware of it, notify the other party, specifying the
      nature of that Termination Event and each Affected Transaction and will
      also give such other information about that Termination Event as the other
      party may reasonably require.

      (ii) Transfer to Avoid Termination Event. If either an Illegality under
      Section 5(b)(i)(1) or a Tax Event occurs and there is only one Affected
      Party, or if a Tax Event Upon Merger occurs and the Burdened Party is the
      Affected Party, the Affected Party will, as a condition to its right to
      designate an Early Termination Date under Section 6(b)(iv), use all
      reasonable efforts (which will not require such party to incur a loss,
      excluding immaterial, incidental expenses) to transfer within 20 days
      after it gives notice under Section 6(b)(i) all its rights and obligations
      under this Agreement in respect of the Affected Transactions to another of
      its Offices or Affiliates so that such Termination Event ceases to exist.

      If the Affected Party is not able to make such a transfer it will give
      notice to the other party to that effect within such 20 day period,
      whereupon the other party may effect such a transfer within 30 days after
      the notice is given under Section 6(b)(i).

      Any such transfer by a party under this Section 6(b)(ii) will be subject
      to and conditional upon the prior written consent of the other party,
      which consent will not be withheld if such other party's policies in
      effect at such time would permit it to enter into transactions with the
      transferee on the terms proposed.

      (iii) Two Affected Parties. If an Illegality under Section 5(b)(i)(1) or a
      Tax Event occurs and there are two Affected Parties, each party will use
      all reasonable efforts to reach agreement within 30 days after notice
      thereof is given under Section 6(b)(i) on action to avoid that Termination
      Event.

      (iv) Right to Terminate. If: --

            (1) a transfer under Section 6(b)(ii) or an agreement under Section
            6(b)(iii), as the case may be, has not been effected with respect to
            all Affected Transactions within 30 days after an Affected Party
            gives notice under Section 6(b)(i); or

            (2) an Illegality under Section 5(b)(i)(2), a Credit Event Upon
            Merger or an Additional Termination Event occurs, or a Tax Event
            Upon Merger occurs and the Burdened Party is not the Affected Party,

      either party in the case of an Illegality, the Burdened Party in the case
      of a Tax Event Upon Merger, any Affected Party in the case of a Tax Event
      or an Additional Termination Event if there is more than one Affected
      Party, or the party which is not the Affected Party in the case of a
      Credit Event Upon Merger or an Additional Termination Event if there is
      only one Affected Party may, by not more than 20 days notice to the other
      party and provided that the relevant Termination Event is then


                                       8
<PAGE>

      continuing, designate a day not earlier than the day such notice is
      effective as an Early Termination Date in respect of all Affected
      Transactions.

(c) Effect of Designation.

      (i) If notice designating an Early Termination Date is given under Section
      6(a) or (b), the Early Termination Date will occur on the date so
      designated, whether or not the relevant Event of Default or Termination
      Event is then continuing.

      (ii) Upon the occurrence of effective designation of an Early Termination
      Date, no further payments or deliveries under Section 2(a)(i) or 2(e) in
      respect of the Terminated Transactions will be required to be made, but
      without prejudice to the other provisions of this Agreement. The amount,
      if any, payable in respect of an Early Termination Date shall be
      determined pursuant to Section 6(e).

(d) Calculations.

      (i) Statement. On or as soon as reasonably practicable following the
      occurrence of an Early Termination Date, each party will make the
      calculations on its part, if any, contemplated by Section 6(e) and will
      provide to the other party a statement (1) showing, in reasonable detail,
      such calculations (including all relevant quotations and specifying any
      amount payable under Section 6(e)) and (2) giving details of the relevant
      account to which any amount payable to it is to be paid. In the absence of
      written confirmation from the source of a quotation obtained in
      determining a Market Quotation, the records of the party obtaining such
      quotation will be conclusive evidence of the existence and accuracy of
      such quotation.

      (ii) Payment Date. An amount calculated as being due in respect of any
      Early Termination Date under Section 6(e) will be payable on the day that
      notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated or occurs as a result of an Event of
      Default) and on the day which is two Local Business Days after the day on
      which notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated as a result of a Termination Event).
      Such amount will be paid together with (to the extent permitted under
      applicable law) interest thereon (before as well as after judgment) in
      the Termination Currency, from (and including) the relevant Early
      Termination Date to (but excluding) the date such amount is paid, at the
      Applicable Rate. Such interest will be calculated on the basis of daily
      compounding and the actual number of days elapsed.

(e) Payments on Early Termination. If an Early Termination Date occurs, the
following provisions shall apply based on the parties' election in the Schedule
of a payment measure, either "Market Quotation" or "Loss", and a payment method,
either the "First Method" or the "Second Method". If the parties fail to
designate a payment measure or payment method in the Schedule, it will be deemed
that "Market Quotation" or the "Second Method", as the case may be, shall apply.
The amount, if any, payable in respect of an Early Termination Date and
determined pursuant to this Section will be subject to any Set-off.

      (i) Events of Default. If the Early Termination Date results from an Event
      of Default: --

            (1) First Method and Market Quotation. If the First Method and
            Market Quotation apply, the Defaulting Party will pay to the
            Non-defaulting Party the excess, if a positive number, of (A) the
            sum of the Settlement Amount (determined by the Non-defaulting
            Party) in respect of the Terminated Transactions and the Termination
            Currency Equivalent of the Unpaid Amounts owing to the
            Non-defaulting Party over (B) the Termination Currency Equivalent of
            the Unpaid Amounts owing to the Defaulting Party.

            (2) First Method and Loss. If the First Method and Loss apply, the
            Defaulting Party will pay to the Non-defaulting Party, if a positive
            number, the Non-defaulting Party's Loss in respect of this
            Agreement.

            (3) Second Method and Market Quotation. If the Second Method and
            Market Quotation apply, an amount will be payable equal to (A) the
            sum of the Settlement Amount (determined by the


                                       9
<PAGE>

            Non-defaulting Party) in respect of the Terminated Transactions and
            the Termination Currency Equivalent of the Unpaid Amounts owing to
            the Non-defaulting Party less (B) the Termination Currency
            Equivalent of the Unpaid Amounts owing to the Defaulting Party. If
            that amount is a positive number, the Defaulting Party will pay it
            to the Non-defaulting Party; if it is a negative number, the
            Non-defaulting Party will pay the absolute value of that amount to
            the Defaulting Party.

            (4) Second Method and Loss. If the Second Method and Loss apply, an
            amount will be payable equal to the Non-defaulting Party's Loss in
            respect of this Agreement. If that amount is a positive number, the
            Defaulting Party will pay it to the Non-defaulting Party; if it is a
            negative number, the Non-defaulting Party will pay the absolute
            value of that amount to the Defaulting Party.

      (iii) Termination Events. If the Early Termination Date results from a
      Termination Event: --

            (1) One Affected Party. If there is one Affected Party, the amount
            payable will be determined in accordance with Section 6(e)(i)(3), if
            Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
            except that, in either case, references to the Defaulting Party and
            to the Non-defaulting Party will be deemed to be references to the
            Affected Party and the party which is not the Affected Party,
            respectively, and, if Loss applies and fewer than all the
            Transactions are being terminated, Loss shall be calculated in
            respect of all Terminated Transactions.

            (2) Two Affected Parties. If there are two Affected Parties: --

                  (A) if Market Quotation applies, each party will determine a
                  Settlement Amount in respect of the Terminated Transactions,
                  and an amount will be payable equal to (I) the sum of (a)
                  one-half of the difference between the Settlement Amount of
                  the party with the higher Settlement Amount ("X") and the
                  Settlement Amount of the party with the lower Settlement
                  Amount ("Y") and (b) the Termination Currency Equivalent of
                  the Unpaid Amounts owing to X less (II) the Termination
                  Currency Equivalent of the Unpaid Amounts owing to Y; and

                  (B) if Loss applies, each party will determine its Loss in
                  respect of this Agreement (or, if fewer than all the
                  Transactions are being terminated, in respect of all
                  Terminated Transactions) and an amount will be payable equal
                  to one-half of the difference between the Loss of the party
                  with the higher Loss ("X") and the Loss of the party with the
                  lower Loss ("Y").

            If the amount payable is a positive number, Y will pay it to X; if
            it is a negative number, X will pay the absolute value of that
            amount to Y.

      (iii) Adjustment for Bankruptcy. In circumstances where an Early
      Termination Date occurs because "Automatic Early Termination" applies in
      respect of a party, the amount determined under this Section 6(e) will be
      subject to such adjustments as are appropriate and permitted by law to
      reflect any payments or deliveries made by one party to the other under
      this Agreement (and retained by such other party) during the period from
      the relevant Early Termination Date to the date for payment determined
      under Section 6(d)(ii).

      (iv) Pre-Estimate. The parties agree that if Market Quotation applies an
      amount recoverable under this Section 6(e) is a reasonable pre-estimate of
      loss and not a penalty. Such amount is payable for the loss of bargain and
      the loss of protection against future risks and except as otherwise
      provided in this Agreement neither party will be entitled to recover any
      additional damages as a consequence of such losses.


                                       10

7. Transfer

Subject to Section 6(b)(ii), neither this Agreement nor any interest or
obligation in or under this Agreement may be transferred (whether by way of
security or otherwise) by either party without the prior written consent of the
other party, except that: --

(a) a party may make such a transfer of this Agreement pursuant to a
consolidation or amalgamation with, or merger with or into, or transfer of all
or substantially all its assets to, another entity (but without prejudice to any
other right or remedy under this Agreement); and

(b) a party may make such a transfer of all or any part of its interest in any
amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void.

8. Contractual Currency

(a) Payment in the Contractual Currency. Each payment under this Agreement will
be made in the relevant currency specified in this Agreement for that payment
(the "Contractual Currency"). To the extent permitted by applicable law, any
obligation to make payments under this Agreement in the Contractual Currency
will not be discharged or satisfied by any tender in any currency other than the
Contractual Currency, except to the extent such tender results in the actual
receipt by the party to which payment is owed, acting in a reasonable manner and
in good faith in converting the currency so tendered into the Contractual
Currency, of the full amount in the Contractual Currency of all amounts payable
in respect of this Agreement. If for any reason the amount in the Contractual
Currency so received falls short of the amount in the Contractual Currency
payable in respect of this Agreement, the party required to make the payment
will, to the extent permitted by applicable law, immediately pay such additional
amount in the Contractual Currency as may be necessary to compensate for the
shortfall. If for any reason the amount in the Contractual Currency so received
exceeds the amount in the Contractual Currency payable in respect of this
Agreement, the party receiving the payment will refund promptly the amount of
such excess.

(b) Judgments. To the extent permitted by applicable law, if any judgment or
order expressed in a currency other than the Contractual Currency is rendered
(i) for the payment of any amount owing in respect of this Agreement, (ii) for
the payment of any amount relating to any early termination in respect of this
Agreement or (iii) in respect of a judgment or order of another court for the
payment of any amount described in (i) or (ii) above, the party seeking
recovery, after recovery in full of the aggregate amount to which such party is
entitled pursuant to the judgment or order, will be entitled to receive
immediately from the other party the amount of any shortfall of the Contractual
Currency received by such party as a consequence of sums paid in such other
currency and will refund promptly to the other party any excess of the
Contractual Currency received by such party as a consequence of sums paid in
such other currency if such shortfall or such excess arises or results from any
variation between the rate of exchange at which the Contractual Currency is
converted into the currency of the judgment or order for the purposes of such
judgment or order and the rate of exchange at which such party is able, acting
in a reasonable manner and in good faith in converting the currency received
into the Contractual Currency, to purchase the Contractual Currency with the
amount of the currency of the judgment or order actually received by such party.
The term "rate of exchange" includes, without limitation, any premiums and costs
of exchange payable in connection with the purchase of or conversion into the
Contractual Currency.

(c) Separate Indemnities. To the extent permitted by applicable law, these
indemnities constitute separate and independent obligations from the other
obligations in this Agreement, will be enforceable as separate and independent
causes of action, will apply notwithstanding any indulgence granted by the party
to which any payment is owed and will not be affected by judgment being obtained
or claim or proof being made for any other sums payable in respect of this
Agreement.

(d) Evidence of Loss. For the purpose of this Section 8, it will be sufficient
for a party to demonstrate that it would have suffered a loss had an actual
exchange or purchase been made.


                                       11

9. Miscellaneous

(a) Entire Agreement. This Agreement constitutes the entire agreement and
understanding of the parties with respect to its subject matter and supersedes
all oral communication and prior writings with respect thereto.

(b) Amendments. No amendment, modification or waiver in respect of this
Agreement will be effective unless in writing (including a writing evidenced by
a facsimile transmission) and executed by each of the parties or confirmed by an
exchange of telexes or electronic messages on an electronic messaging system.

(c) Survival of Obligations. Without prejudice to Sections 2(a)(iii) and
6(c)(ii), the obligations of the parties under this Agreement will survive the
termination of any Transaction.

(d) Remedies Cumulative. Except as provided in this Agreement, the rights,
powers, remedies and privileges provided in this Agreement are cumulative and
not exclusive of any rights, powers, remedies and privileges provided by law.

(e) Counterparts and Confirmations.

      (i) This Agreement (and each amendment, modification and waiver in respect
      of it) may be executed and delivered in counterparts (including by
      facsimile transmission), each of which will be deemed an original.

      (ii) The parties intend that they are legally bound by the terms of each
      Transaction from the moment they agree to those terms (whether orally or
      otherwise). A Confirmation shall be entered into as soon as practicable
      and may be executed and delivered in counterparts (including by facsimile
      transmission) or be created by an exchange of telexes or by an exchange of
      electronic messages on an electronic messaging system, which in each case
      will be sufficient for all purposes to evidence a binding supplement to
      this Agreement. The parties will specify therein or through another
      effective means that any such counterpart, telex or electronic message
      constitutes a Confirmation.

(f) No Waiver of Rights. A failure or delay in exercising any right, power or
privilege in respect of this Agreement will not be presumed to operate as a
waiver, and a single or partial exercise of any right, power or privilege will
not be presumed to preclude any subsequent or further exercise of that right,
power or privilege or the exercise of any other right, power or privilege.

(g) Headings. The headings used in this Agreement are for convenience of
reference only and are not to affect the construction of or to be taken into
consideration in interpreting this Agreement.

10. Offices; Multibranch Parties

(a) If Section 10(a) is specified in the Schedule as applying, each party that
enters into a Transaction through an Office other than its head or home office
represents to the other party that, notwithstanding the place of booking office
or jurisdiction of incorporation or organisation of such party, the obligations
of such party are the same as if it had entered into the Transaction through its
head or home office. This representation will be deemed to be repeated by such
party on each date on which a Transaction is entered into.

(b) Neither party may change the Office through which it makes and receives
payments or deliveries for the purpose of Transaction without prior written
consent of the other party.

(c) If a party is specified as a Multibranch Party in the Schedule, such
Multibranch Party may make and receive payments or deliveries under any
Transaction through any Office listed in the Schedule, and the Office through
which it makes and receives payments or deliveries with respect to a Transaction
will be specified in the relevant Confirmation.

11. Expenses

A Defaulting Party will, on demand, indemnify and hold harmless the other party
for and against all reasonable out-of-pocket expenses, including legal fees and
Stamp Tax, incurred by such other party by reason of the enforcement and
protection of its rights under this Agreement or any Credit Support Document


                                       12
<PAGE>

to which the Defaulting Party is a party or by reason of the early termination
of any Transaction, including, but not limited to, costs of collection.

12. Notices

(a) Effectiveness. Any notice or other communication in respect of this
Agreement may be given in any manner set forth below (except that a notice or
other communication under Section 5 or 6 may not be given by facsimile
transmission or electronic messaging system) to the address or number or in
accordance with the electronic messaging system details provided (see the
Schedule) and will be deemed effective as indicated: --

      (i) if in writing and delivered in person or by courier, on the date it is
      delivered;

      (ii) if sent by telex, on the date the recipient's answerback is received;

      (iii) if sent by facsimile transmission, on the date that transmission is
      received by a responsible employee of the recipient in legible form (it
      being agreed that the burden of proving receipt will be on the sender and
      will not be met by a transmission report generated by the sender's
      facsimile machine);

      (iv) if sent by certified or registered mail (airmail, if overseas) or the
      equivalent (return receipt requested), on the date that mail is delivered
      or its delivery is attempted; or

      (v) if sent by electronic messaging system, on the date that electronic
      message is received,

unless the date of that delivery (or attempted delivery) or that receipt, as
applicable, is not a Local Business Day or that communication is delivered (or
attempted) or received, as applicable, after the close of business on a Local
Business Day, in which case that communication shall be deemed given and

13. Governing Law and Jurisdiction

(a) Governing Law. This Agreement will be governed by and construed in
accordance with the law specified an the Schedule.

(b) Jurisdiction. With respect to any suit, action or proceedings relating to
this Agreement ("Proceedings"), each party irrevocably: --

      (i) submits to the jurisdiction of the English courts, if this Agreement
      is expressed to be governed by English law, or to the non-exclusive
      jurisdiction of the courts of the State of New York and the United States
      District Court located in the Borough of Manhattan an New York City, if
      this Agreement is expressed to be governed by the laws of the State of New
      York; and

      (ii) waives any objection which it may have at any time to the laying of
      venue of any Proceedings brought in any such court, waives any claim that
      such Proceedings have been brought in an inconvenient forum and further
      waives the right to object, with respect to such Proceedings, that such
      court does not have any jurisdiction over such party.

Nothing in this Agreement precludes either party from bringing Proceedings in
any other jurisdiction (outside, if this Agreement is expressed to be governed
by English law, the Contracting States, as defined in Section 1(3) of the Civil
Jurisdiction and Judgments Act 1982 or any modification, extension or
re-enactment thereof for the time being in force) nor will the bringing of
Proceedings in any one or more jurisdictions preclude the bringing of
Proceedings in any other jurisdiction.

(c) Service of Process. Each party irrevocably appoints the Process Agent (if
any) specified opposite its name in the Schedule to receive, for it and on its
behalf, service of process in any Proceedings. If for any


                                       13
<PAGE>

reason any party's Process Agent is unable to act as such, such party will
promptly notify the other party and within 30 days appoint a substitute process
agent acceptable to the other party. The parties irrevocably consent to service
of process given in the manner provided for notices in Section 12. Nothing in
this Agreement will affect the right of either party to serve process in any
other manner permitted by law.

(d) Waiver of immunities. Each party irrevocably waives, to the fullest extent
permitted by applicable law, with respect to itself and its revenues and assets
(irrespective of their use or intended use), all immunity on the grounds of
sovereignty or other similar grounds from (i) suit, (ii) jurisdiction of any
court, (iii) relief by way of injunction, order for specific performance or for
recovery of property, (iv) attachment of its assets (whether before or after
judgment) and (v) execution or enforcement of any judgment to which it or its
revenues or assets might otherwise be entitled in any Proceedings in the courts
of any jurisdiction and irrevocably agrees, to the extent permitted by
applicable law, that it will not claim any such immunity in any Proceedings.

"Loss" means, with respect to this Agreement or one or more Terminated
Transactions, as the case may be, and a party, the Termination Currency
Equivalent of an amount that party reasonably determines in good faith to be its
total losses and costs (or gain, in which case expressed as a negative number)
in connection with this Agreement or that Terminated Transaction or group of
Terminated Transactions, as the case may be, including any loss of bargain, cost
of funding or, at the election of such party but without duplication, loss or
cost incurred as a result of its terminating, liquidating, obtaining or
reestablishing any hedge or related trading position (or any gain resulting from
any of them). Loss includes losses and costs (or gains) in respect of any
payment or delivery required to have been made (assuming satisfaction of each
applicable condition precedent) on or before the relevant Early Termination Date
and not made, except, so as to avoid duplication, if Section 6(e)(i)(1) or (3)
or 6(e)(ii)(2)(A) applies. Loss does not include a party's legal fees and
out-of-pocket expenses referred to under Section 11. A party will determine its

party may (but need not) determine its Loss by reference to quotations of
relevant rates or prices from one or more leading dealers in the relevant
markets.

"Market Quotation" means, with respect to one or more Terminated Transactions
and a party making the determination, an amount determined on the basis of
quotations from Reference Market-makers. Each quotation will be for an amount,
if any, that would be paid to such party (expressed as a negative number) or by
such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document
with respect to the obligations of such party) and the quoting Reference
Market-maker to enter into a transaction (the "Replacement Transaction") that
would have the effect of preserving for such party the economic equivalent of
any payment or delivery (whether the underlying obligation was absolute or
contingent and assuming the satisfaction of each applicable condition precedent)
by the parties under Section 2(a)(i) in respect of such Terminated Transaction
or group of Terminated Transactions that would, but for the occurrence of the
relevant Early Termination Date, have


                                       15
<PAGE>

been required after that date. For this purpose, Unpaid Amounts in respect of
the Terminated Transaction or group or Terminated Transactions are to be
excluded but, without limitation, any payment or delivery that would, but for
the relevant Early Termination Date, have been required (assuming satisfaction
of each applicable condition precedent) after that Early Termination Date is to
be included. The Replacement Transaction would be subject to such documentation
as such party and the Reference Market-maker may, in good faith, agree. The
party making the determination (or its agent) will request each Reference
Market-maker to provide its quotation to the extent reasonably practicable as of
the same day and time (without regard to different time zones) on or as soon as
reasonably practicable after the relevant Early Termination Date. The day and
time as of which those quotations are to be obtained will be selected in good
faith by the party obliged to make a determination under Section 6(e), and, if
each party is so obliged, after consultation with the other. If more than three
quotations are provided, the Market Quotation will be the arithmetic mean of the
quotations, without regard to the quotations having the highest and lowest
values. If exactly three such quotations are provided, the Market Quotation will
be the quotation remaining after disregarding the highest and lowest quotations.
For this purpose, if more than one quotation has the same highest value or
lowest value, then one of such quotations shall be disregarded. If fewer than
three quotations are provided, it will be deemed that the Market Quotation in
respect of such Terminated Transaction or group of Terminated Transactions
cannot be determined.

"Non-default Rate" means a rate per annum equal to the cost (without proof or
evidence of any actual cost) to the Non-defaulting Party (as certified by it) if
it were to fund the relevant amount.

"Office" means a branch or office of a party, which may be such party's head or
home office.

the lapse of time or both, would constitute an Event of Default.

selected by the party determining a Market Quotation in good faith (a) from
among dealers of the highest credit standing which satisfy all the criteria that
such party applies generally at the time in deciding whether to offer or to make
an extension of credit and (b) to the extent practicable, from among such
dealers having an office in the same city.

"Relevant Jurisdiction" means, with respect to a party, the jurisdictions (a) in
which the party is incorporated, organised, managed and controlled or considered
to have its seat, (b) where an Office through which the party is acting for
purposes of this Agreement is located, (c) in which the party executes this
Agreement and (d) in relation to any payment, from or through which such payment
is made.

"Scheduled Payment Date" means a date on which a payment or delivery is to be
made under Section 2(a)(i) with respect to a Transaction.

"Set-off" means set-off, offset, combination of accounts, right of retention or
withholding or similar right or requirement to which the payer of an amount
under Section 6 is entitled or subject (whether arising under this Agreement,
another contract, applicable law or otherwise) that is exercised by, or imposed
on, such payer.

"Settlement Amount" means, with respect to a party and any Early Termination
Date, the sum of: --

(a) the Termination Currency Equivalent of the Market Quotations (whether
positive or negative) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation is determined; and

(b) such party's Loss (whether positive or negative and without reference to any
Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not (in
the reasonable belief of the party making the determination) produce a
commercially reasonable result.

"Specified Entity" has the meaning specified in the Schedule.


                                       16

(including an agreement with respect thereto) now existing or hereafter entered
into between one party to this Agreement (or any Credit Support Provider of such
party or any applicable Specified Entity of such party) and the other party to
this Agreement (or any Credit Support Provider of such other party or any
applicable Specified Entity of such other party) which is a rate swap
transaction, basis swap, forward rate transaction, commodity swap, commodity
option, equity or equity index swap, equity or equity index option, bond option,
interest rate option, foreign exchange transaction, cap transaction, floor
transaction, collar transaction, currency swap transaction, cross-currency rate
swap transaction, currency option or any other similar transaction (including

Transaction in this Agreement or the relevant confirmation.

"Termination Currency" has the meaning specified in the Schedule.

"Termination Currency Equivalent" means, in respect of any amount denominated in
the Termination Currency, such Termination Currency amount and, in respect of
any amount denominated in a currency other than the Termination Currency (the
"Other Currency"), the amount in the Termination Currency determined by the
party making the relevant determination as being required to purchase such
amount of such Other Currency as at the relevant Early Termination Date, or, if
the relevant Market Quotation or Loss (as the case may be), is determined as of
a later date, that later date, with the Termination Currency at the rate equal
to the spot exchange rate of the foreign exchange agent (selected as provided
below) for the purchase of such Other Currency with the Termination Currency at
or about 11:00 a.m. (in the city in which such foreign exchange agent is
located) on such date as would be customary for the determination of such a rate
for the purchase of such Other Currency for value on the relevant Early
Termination Date or that later date. The foreign exchange agent will, if only
one party is obliged to make a determination under Section 6(e), be selected in
good faith by that party and otherwise will be agreed by the parties.

                                       17
<PAGE>

value of that which was (or would have been) required to be delivered as of the
originally scheduled date for delivery, in each case together with (to the
extent permitted under applicable law) interest, in the currency of such
amounts, from (and including) the date such amounts or obligations were or would
have been required to have been paid or performed to (but excluding) such Early

elapsed. The fair market value of any obligation referred to in clause (b) above
shall be reasonably determined by the party obliged to make the determination

      make any deduction or withholding for or on account of any Tax from any
      payment (other than interest under Section 2(e), 6(d)(ii) or 6(e) of this
      Agreement) to be made by it to the other party under this Agreement. In
      making this representation, it may rely on:

      (i)   the accuracy of any representation made by the other party pursuant
            to Section 3(f) of this Agreement; 

      (ii)  the satisfaction of the agreement contained in Section 4(a)(i) or
            4(a)(iii) of this Agreement and the accuracy and effectiveness of

            or 4(a)(iii) of this Agreement; and

      (iii) the satisfaction of the agreement of the other party contained in

                  understood that information and explanations related to the

            otherwise".

(4)   Amendment to Section 6. In section 6 make the following amendments: 

      (i)   Section 6(a) is amended by deleting the words "all outstanding
            Transactions" where they appear and inserting instead the words "the
            Relevant Swap Transaction".

      (ii)  Add a new section 6(aa):

            "(aa) Restricted Termination Rights.

            (i)   Termination by Party B: Party B must not designate an Early
                  Termination Date without the prior written consent of the Note
                  Trustee.

            (ii)  Consultation with Party A: Each Party may only designate an
                  Early Termination Date following prior consultation with the
                  other Party as to the timing of the Early Termination Date.
                  Subject to its duties under the Master Trust Deed and the
                  Series Notice, Party B may exercise any rights in its capacity
                  as holder of the Purchased Receivables only on the
                  instructions of the Note Trustee and only after consultation
                  between Party A and Note Trustee. Party B may only designate
                  an Early Termination Date at the direction of the Trust
                  Manager.

            (iii) Party A's limited rights in relation to Tax Event:
                  Notwithstanding Part 1(b)(iv) of this Schedule, Party A may
                  designate an Early Termination Date if it is an Affected Party
                  following a Tax Event but only if the Note Trustee is
                  satisfied that the Noteholders and Couponholders will be paid
                  in full all principal and interest outstanding on the Notes.

            (iv)  Illegality: The parties agree that [unless this Section
                  6(aa)(iv) is specified not to apply in the Relevant
                  Confirmation,] imposition by any Agency of an Australian
                  jurisdiction of any exchange controls, restrictions or
                  prohibitions will not constitute an Illegality for the
                  purposes of Section 5(b)(i) and Party A will not be entitled
                  to designate an Early Termination Date, and in those
                  circumstances, payment by Party B in accordance with section
                  2(f) will continue to be proper performance of its payment
                  obligation and Party A's obligations will be unaffected, to
                  the extent of Party B's payments under section 2(f).

            (v)   Transfer where Party B does not gross-up: If any payment by
                  Party B to Party A under this Agreement is, or is likely to
                  be, made subject to any deduction or withholding on account of
                  Tax, Party B will endeavour to procure the substitution as
                  principal obligor under this Agreement in respect of each
                  affected Transaction of a Party B incorporated in another
                  jurisdiction approved by Party A and the Note Trustee and in
                  respect of which the Designated Rating Agencies confirm that
                  the substitution will not cause a reduction or withdrawal of
                  the rating of the Notes.

      (iii) In section 6(b)(ii), add the words "so long as the transfer in
            respect of that Transaction would not lead to a rating downgrade of
            any rated debt of Party B that is secured under the Security Trust
            Deed" after the words "ceases to exist" at the
<PAGE>

11


                  end of the first paragraph.

      (iv)  In section 6(e), delete the sentence "The amount, if any, payable in
            respect of an Early Termination Date and determined pursuant to this
            Section will be subject to any Set-off." at the end of the first
            paragraph.

(5)   In section 9, add the following new paragraphs: 

      "(h)  Further Assurances. Each party shall, upon request by the other
            party (the "requesting party") at the expense of the requesting
            party, perform all such acts and execute all such agreements,
            assurances and other documents and instruments as the requesting
            party reasonably requires and which are within the powers of that
            party to assure and confirm the rights and powers afforded, created
            or intended to be afforded or created, under or in relation to this
            Agreement and each Transaction or other dealing which occurs under
            or is contemplated by it.

      (i)   Recorded Conversation. Each party:

            (A)   consents to the recording of the telephone conversations of
                  trading and marketing personnel of that party and its
                  Affiliates in connection with this Agreement or any potential
                  Transaction; and

            (B)   agrees to obtain any necessary consent of, and give notice of
                  such recording to, such personnel of it and its Affiliates.

      (j)   ISDA Definitions: This Agreement, each Confirmation and each
            Transaction are subject to the 1991 ISDA Definitions (as published
            by the International Swap Dealers Association, Inc.) (the "ISDA
            Definitions"), and will be governed in all respects by any
            provisions set forth in the ISDA Definitions, without regard to any
            amendments to the ISDA Definitions made after the date of this
            Agreement. The ISDA Definitions are incorporated by reference in,
            and shall be deemed to be part of, this Agreement and each
            Confirmation.

      (k)   Inconsistency: In the event of any inconsistency between any two or
            more of the following documents, they shall take precedence over
            each other in the following descending order:

            (i)   any Confirmation;
            (ii)  the Schedule to the Master Agreement;
            (iii) the other provisions of the Master Agreement;
            (iv)  the ISDA Definitions."

(6)   Facsimile Transmissions: Replace Section 12(a)(iii) with: 

      "(iii) if sent by facsimile, on production of a transmission report by the
            machine from which the facsimile was sent which indicates that the
            facsimile was sent in its entirety to the facsimile number of the
            recipient notified for the purpose of this Section unless the
            recipient notifies the sender within 24 hours of the facsimile being
            sent that the facsimile was not received in its entirety in legible
            form;"

(7)   Definitions: In section 14: 

      (i)   add a new paragraph: 
            "Unless otherwise defined in this Agreement, terms defined in the 
            Security
<PAGE>

12


            Trust Deed (either expressly or by incorporation by reference) have
            the same meaning where used in this Agreement." 

      (ii)  Insert the following definitions in its appropriate alphabetical
            places in Section 14: 

            "'Relevant Swap Transaction' means, in relation to Class A Notes,
            each Transaction which is a Currency Swap for Class A Notes only,
            and in relation to Class B Notes, each Transaction which is a
            Currency Swap for Class B Notes only." 

            "'Security Trust Deed' means the Series 1998-1G WST Trust Security
            Trust Deed dated on or about the date of this Agreement between
            Party B as chargor, Perpetual Trustee Company Limited as security
            trustee, the Trust Manager and Party A as note trustee."

      (iii) Swap Transaction. Any reference to a:

            (a)   "Swap Transaction" in the 1991 ISDA Definitions is deemed to
                  be a reference to a "Transaction" for the purpose of
                  interpreting this Agreement or any Confirmation; and

            (b)   "Transaction" in this Agreement or any Confirmation is deemed
                  to be a reference to a "Swap Transaction" for the purpose of
                  interpreting the 1991 ISDA Definitions.

      (iv)  In the definition of "Market Quotation", on line 1 on page 16 of
            this Agreement, replace the words "been required after that date."
            with: "been required after that date and, in respect of each
            Terminated Transaction which is a Relevant Swap Transaction, on the
            basis that the Housing Loan Principal as defined in Series Notice
            referred to in the Terminated Transaction will thereafter have an
            amortisation schedule based on a constant prepayment rate per annum
            ("CPR") equal to:

            (a)   [XX%], if the Replacement Transaction is calculated within one
                  year of the Effective Date of the Terminated Transaction; or

            (b)   if the Replacement Transaction is calculated later than one
                  year after the Effective Date of the Terminated Transaction,
                  the arithmetic mean of four CPRs most recently published prior
                  to the relevant quotation on Bloomberg monitor service in
                  respect of the Class of Notes applicable to the Terminated
                  Transaction (based on data provided to Bloomberg by the Trust
                  Manager)."

(8)   Other Provisions, including Credit Support: 
Insert the following Sections 15, 16, 17, 18, 19, 20 and 21 after Section 14:

      "15.  Segregation: 

            The liability of Party B under this Agreement is several and is
            separate in respect of each Relevant Swap Transaction. The failure
            of Party B to perform its obligations in respect of any Relevant
            Swap Transaction shall not release Party B from its obligations
            under this Agreement or under any other Relevant Swap Transaction in
            respect of any other Notes issued by Party B. Nothing in this
            Agreement affects the respective priority rankings of claims against
            the Mortgaged Property of Party B under the Security Trust Deed.
            Without limiting the generality of the foregoing, the provisions of
            this Agreement shall have effect separately and severally in respect
            of each Relevant Swap Transaction and shall be enforceable by or
            against Party B as though a separate agreement applied between Party
            A and Party B for
<PAGE>

13


            each Relevant Swap Transaction, so that (among other things):

            (i)   this Agreement together with each Confirmation relating to a
                  Relevant Swap Transaction will form a single separate
                  agreement between Party A and Party B and references to the
                  respective obligations (including references to payment
                  obligations generally and in the context of provisions for the
                  netting of payments and the calculation of amounts due on
                  early termination) of Party A and Party B shall be construed
                  accordingly as a several reference to each mutual set of
                  obligations arising under each such separate agreement between
                  Party A and Party B; 

            (ii)  representations made and agreements entered into by the
                  parties under this Agreement are made and entered separately
                  and severally by Party B in respect of each Relevant Swap
                  Transaction and may be enforced by Party B against Party A
                  separately and severally in respect of each Relevant Swap
                  Transaction;

            (iii) rights of termination, and obligations and entitlements
                  consequent upon termination, only accrue to Party A against
                  Party B separately and severally in respect of each Relevant
                  Swap Transaction, and only accrue to Party B against Party A
                  separately and severally in respect of each Relevant Swap
                  Transaction; and

            (iv)  the occurrence of an Event of Default or Termination Event in
                  respect of a Relevant Swap Transaction does not in itself
                  constitute an Event of Default or Termination Event in respect
                  of any other Relevant Swap Transaction." 

      16. Recourse

            Party B enters into this Agreement in its capacity as Trustee of the
            Trust, and Clause 3.3(b) of the Series Notice applies to this
            Agreement as if set out in full. Clause 16 of the Security Trust
            Deed shall apply to govern Party A's priority to moneys received
            from the sale of Assets or other enforcement of the Charge under the
            Security Trust Deed. This Section 16:

            (i)   applies even though any other provision of this Agreement is
                  not made subject to it; and 

            ii)   overrides any other provision of this Agreement which is
                  inconsistent with it.

      17.   The Manager

            Party A acknowledges that the Manager will, at the request of Party
            B, perform the day to day management of the Trust on the terms and
            conditions of the Master Trust Deed and Series Notice. Unless
            expressly advised to the contrary in writing by Party B from time to
            time, any rights or obligations of Party B under this Agreement may
            be exercised or satisfied (as the case may be) by the Manager on
            behalf of Party B and Party A is not obliged to enquire as to the
            authority of the
<PAGE>

14


            Manager to take such action on behalf of Party B. Except where the
            context otherwise requires, references in this Agreement to a
            "party" to this Agreement are to Party A or Party B.

      18.   Trust Deed

            The parties acknowledge and agree that, for the purposes of the
            Master Trust Deed and the Trust Documents, this Agreement is a
            "Hedge Agreement" and Party A is a "Swap Provider" and "Support
            Facility Provider"." 

      19.   Replacement Currency Swap

            (a)   If this Agreement is terminated, Party B may, at the direction
                  of the Trust Manager, enter into one or more currency swaps
                  which replace the Transactions under this Agreement
                  (collectively a "Replacement Currency Swap") but only on the
                  condition that the Settlement Amount payable (if any) by Party
                  B to Party A upon termination of this Agreement will be paid
                  in full when due in accordance with the Series Notice and this
                  Agreement.

            (b)   If the condition in section 19(a) is satisfied, Party B may
                  enter into the Replacement Currency Swap and if it does so it
                  must direct the Replacement Currency Swap to pay any upfront
                  premium to enter into the Replacement Currency Swap due to
                  Party B directly to Party A in satisfaction of and to the
                  extent of Party B's obligation to pay the Settlement Amount to
                  Party A as referred to in section 19(a), and to the extent
                  that such premium is not greater than or equal to the
                  Settlement Amount, the balance may be satisfied by Party B as
                  a Trust Expense (as defined in the Series Notice).

            (c)   The obligations of Party B (and the rights of Party A) under
                  this section 19 constitute separate and independent
                  obligations of Party B (and rights of Party A) and shall
                  survive the termination of this Agreement.

      20.   Credit Support

            (a)   In consideration of Party B entering into an agreement on the
                  same material terms as this Agreement with the Credit Support
                  Provider (the "Other Agreement") and Transactions under that
                  Agreement on the same material terms as Transactions under
                  this Agreement, the Credit Support Provider hereby
                  unconditionally guarantees to Party B the payment by Party A
                  of moneys which are payable by Party A under a Relevant Swap
                  Transaction (on terms set out in this Agreement and in the
                  Confirmation for that Relevant Swap Transaction) (the "Payable
                  Moneys") to Party B in the event that Party A defaults in the
                  payment of those Payable Moneys.

            (b)   If Party B has not been, or Party A reasonably expects that
                  Party B is not going to be, paid all or any part of the
                  presently payable Payable Moneys by Party A, then Party A or
                  Party B may by notice to the Credit Support Provider demand
                  payment of the Payable Moneys in respect of which demand is
                  being made. The Credit Support Provider's obligations to pay
                  the presently payable Payable Moneys which have not been paid
                  by Party A shall not, however, be conditional upon the Credit
                  Support Provider receiving such notice of demand.

            (c)   The Credit Support Provider agrees that it will not, unless
                  and until all the present and prospective Payable Moneys have
                  been paid, exercise
<PAGE>

15


                  any rights of subrogation which it may acquire due to its
                  payment of Payable Moneys under section 20(a).

            (d)   All payments by the Credit Support Provider shall be made in
                  the currency in which the Payable Moneys are denominated.

            (e)   Party B agrees that, without affecting its rights under clause
                  21, to the extent that the Credit Support Provider pays the
                  Payable Moneys and thereby avoids or remedies a default by
                  Party A, Party B shall not be entitled to designate an Early
                  Termination Date in respect of that default by Party A, and
                  such a payment by the Credit Support Provider shall be deemed
                  to be an "actual payment" as referred to in line 6 of section
                  2(e) of this Agreement.

            (f)   The provisions of this section 20 shall constitute irrevocable
                  obligations of the Credit Support Provider until a notice of
                  revocation is served by the Credit Support Provider on Party
                  B, but such a notice cannot and shall not be served without
                  the prior written consent of Party A, the Note Trustee and the
                  Trust Manager in consultation with the Designated Rating
                  Agencies.

      21.   Credit Support Provider Transactions 

            (a)   The Credit Support Provider may give a Substitution Notice to
                  Party B specifying a Transaction which shall be substituted
                  under this Section 21 (a "Replaced Transaction"), but only on
                  the condition that a Credit Event has occurred in respect of
                  Party A.

            (b)   If the Credit Support Provider gives a Substitution Notice
                  under paragraph 21(a), then either:

                  (i)   a Substitute Transaction shall become effective and the
                        Effective Date shall be the date specified in the
                        Substitution Notice; or

                  (ii)  both:

                        (A)   Party B, the Credit Support Provider and the Trust
                              Manager must enter into an Equivalent Transaction
                              with a suitably rated counterparty procured by the
                              Credit Support Provider and accepted by Party B,
                              the Trust Manager and the Note Trustee (the "New
                              Currency Swap Provider") and the Effective Date
                              shall be the date specified in the Substitution
                              Notice as the Effective Date for the
                              Equivalent-Other Transaction; and

                        (B)   an Equivalent-Other Transaction shall become
                              effective and the Effective Date shall be the date
                              specified in the Substitution Notice. The New
                              Currency Swap Provider must sign, and Party B, the
                              Credit Support Provider and the Trust Manager must
                              countersign, an accession as provided
<PAGE>

16


                        for in the Confirmation for the Equivalent-Other
                        Transaction.

                  For the avoidance of doubt, a Substitution Notice may specify
                  that a Substitution Transaction will become effective in
                  accordance with paragraph (b)(i) or that an Equivalent
                  Transaction and an Equivalent Other Transaction will become
                  effective in accordance with paragraphs (b)(ii)(A) and (B), or
                  that either a Transaction under paragraph (b)(i) or
                  Transactions under paragraphs (b)(ii)(A) and (B) shall become
                  effective as alternatives. If the Substitution Notice
                  specifies that, as alternatives, the Transaction or
                  Transactions under paragraphs (b)(i) or (b)(ii)(A) and (B)
                  shall become effective, and if a suitably rated counterparty
                  is not procured by the Credit Support Provider under paragraph
                  (b)(ii)(A), the Substitute Transaction must become effective
                  in accordance with paragraph (b)(i).

            (c)   On the date on which the Transactions become effective in
                  accordance with a Substitution Notice under either paragraph
                  (b)(i) or (b)(ii): 

                  (i)   the Replaced Transaction shall terminate; and
                  (ii)  the Other Transaction shall terminate.

            (d)   No Settlement Amount or other amount under section 6 or
                  section 11 shall be payable by, or to, Party B (as the case
                  may be) upon the termination of the Transactions under
                  paragraphs (c)(i) and (ii), because the Transactions specified
                  in paragraphs (b)(i), or (b)(ii)(A) and (B), as the case may
                  be, shall have the effect of preserving for Party B the
                  economic equivalent of the payments under the Transactions
                  which are being terminated. 

            (e)   Definitions. For the purposes of this Section 21:
                  "Credit Event" means, in relation to Party A, the occurrence
                  at any time of any of the following events with respect to
                  Party A:

                  (i)(A) Failure by Party A to make, when due, any payment
                         under the Replaced Transaction required to be made by
                         it if such failure is not remedied on or before the
                         tenth local Business Day after notice of such failure
                         is given to Party A; and

                  (B)   On any day on which a failure by Party A under paragraph
                        (e)(i)(A) is subsisting:

                        (I)   the Market Value of a floating rate Reference
                              Obligation is below the Initial Price of such by
                              more than the Price Decline Requirement; or

13.   Elections and Variables

      (a)   Security Interest for "Obligations"             

            The term "Obligations" as used in this Annex does not include any
            additional obligations. For the avoidance of doubt, in respect of
            the Obligations which are specified in the Relevant Swap
            Transactions, any assumptions made for the purposes of calculating
            the Peak Exposure in Paragraph 13(b)(i) or the Benefit Exposure in
            Paragraph 13(b)(iv)(A) must not be applied or otherwise taken into
            account for the purpose of calculating the Obligations, since those
            assumptions are theoretical only and do not accurately reflect any
            actual Obligations.

      (b)   Credit Support Obligations

            (i)   Delivery Amount, Return Amount and Credit Support Amount

                  "Delivery Amount" and "Return Amount" each has the meaning
                  specified in Paragraph 3.

                  "Credit Support Amount" means, for any Valuation Date:

                  (A)   (I)   with respect to Party A as the Secured Party,
                              Party A's Exposure for that Valuation Date; or

                        (II)  with respect to Party B as the Secured Party,
                              Party B's Peak Exposure for that Valuation Date;
                              plus

                  (B)   the aggregate of all Independent Amounts applicable to
                        the Pledgor, if any; minus

                  (C)   all Independent Amounts applicable to the Secured Party,
                        if any; minus

                  (D)   the Pledgor's Threshold, 

                  provided, however, that the Credit Support Amount will be
                  deemed to be zero whenever the calculation of Credit Support
                  Amount yields a number less than zero.

                  "Peak Exposure" means the amount equal to Party B's maximum
                  credit exposure in respect of a Replacement Transaction
                  entered into on a date three months after the Valuation Date,
                  calculated by the Valuation Agent using its swap credit
                  exposure methodology to a 99% confidence interval, as that
                  methodology is updated to reflect, without limitation, the
                  levels of volatility current as at the Valuation Time for the
                  differential between USD-LIBOR-BBA and AUD-BBR-BBSW (each rate
                  with a Designated Maturity of three months) and the A$-US$
                  forward exchange rates, and assuming that from that Valuation
                  Date:

                        (I)   the remaining term of the Relevant Swap
                              Transaction is calculated on the basis that the
                              Termination Date is a date, no later than 31 years
                              after the Effective Date of the first Transaction
                              in respect of the Notes, calculated by applying
                              the assumptions specified in subparagraph (II)
                              below;

                        (II)  the Floating Rate Payer Amounts and Exchange
                              Amounts are calculated on the basis that the
                              Housing Loan Principal has an amortisation
                              schedule based on a constant prepayment rate of 5%
                              per annum thereafter,

                  Not applicable.

            (iv)  Thresholds

                  (A)   "Independent Amount" means with respect to Party A, the
                        Additional Spread. "Additional Spread" means the amount
                        equal to the excess of Party B's Benefit Exposure less
                        Party B's Exposure, as each is calculated on the same
                        Valuation Date. 

                        "Benefit Exposure" means the amount equal to Party B's
                        Exposure, except calculated on the basis that:

                        (I)   the underlying swap rate for the Replacement
                              Transaction is equal to the underlying swap rate
                              for the Replacement Transaction as quoted by the
                              Reference Market-makers plus 0.25% additional
                              spread on the A$ side of the swap; and 

                        (II)  the remaining term and the Floating Rate Payer

                              assumptions specified in subparagraphs (I) and
                              (II) of the definition of Peak Exposure in
                              paragraph 13(b)(i) above.

                        For the avoidance of doubt, the Additional Spread is
                        intended to represent a maximum additional bid/offer
                        spread of 25 swap points running payable if the
                        bid/offer swap rates quoted to the Secured Party were
                        adjusted from market rates to the benefit of the
                        Reference Market-makers. 

                        "Independent Amount" means with respect to Party B:
                        Zero.

                  (B)   "Threshold"

                              rating that can be assigned to senior long term
                              debt jointly supported by Party A and the Credit
                              Support Provider by Moody's Investors Service Inc
                              ("Moody's") in accordance with Moody's approach to

                       Credit Support Provider Provisions

Each Transaction under this Confirmation shall be capable of being specified as
a Replaced Transaction in accordance with the provisions of Section 21 of the
Agreement. Those provisions shall apply as further specified below.

1.    Definitions for Credit Events

      "Calculation Agent" means the party to the Transaction (or a third party)
      designated as such for the Transaction. The Calculation Agent's
      calculations and determinations shall be made in good faith, in a
      commercially reasonable manner and be binding in the absence of manifest
      error [Credit Support Provider];

      "Initial Price" means, with respect to any Reference Obligation, the
      percentage listed with respect thereto in the definition of Reference
      Obligation herein as the Initial Price;

      "Interest Rate Adjustment Amount" means, with respect to any Reference
      Obligation, the absolute value of the difference between (i) the Mark to
      Market Value and (ii) 100% minus the Initial Price;

      "Mark to Market Value" means, in the determination of the Calculation
      Agent, with respect to any Reference Obligation, on any day, the mark to
      market value payable on that day (expressed as a percentage of the
      notional amount thereof), of a hypothetical interest rate swap commencing
      on the Effective Date between a hypothetical party ("Party X") and a
      counterparty with the highest long term senior debt rating of each Rating
      Agency, which swap has a notional amount equal to the Floating Rate Payer
      Calculation Amount and under which Party X (i) pays the Mark to Market
      Rate plus the Initial Spread and (ii) receives a fixed interest amount
      equal in amount and timing to the coupons on the Reference Obligation. If,
      under such swap, Party X would be due to pay such mark to market value,
      Mark to Market Value will be negative and, if Party X would be due to
      receive such mark to market value, the Mark to Market Value will be
      positive.

      "Market Value" means, in accordance with the Quotation Method, the
      percentage equal to the arithmetic mean of quotations (exclusive of
      accrued but unpaid interest and expressed as a percentage) obtained from
      Dealers with respect to a Valuation Date in the manner provided below. In
      obtaining such price quotations from Dealers, the Calculation Agent will
      request each Dealer to provide firm bid and offer quotations for an
      aggregate amount of the Reference Obligation equal to the Quotation Amount
      to the extent reasonably practicable as of the Valuation Time on such
      Valuation Date. If more than three quotations are provided on such date,
      the Market Value shall be the arithmetic mean of such quotations without
      regard to the quotations having the highest and lowest values. If exactly
      three quotations are provided, the Market Value shall be the quotation
      remaining after disregarding the highest and lowest quotations. For this
      purpose, if more than one quotation has the same highest value or lowest
      value, then one of such quotations shall be disregarded. If exactly two
      quotations are provided, the Market Value shall be the arithmetic mean of
      such quotations. If fewer than two quotations are provided, then the
      Market Value shall be an amount as determined by the Calculation Agent on
      the next Business Day on which at least two quotations are provided by
      Dealers. If the Calculation Agent is unable to calculate the Market Value
      prior to the fifth 


                                                                         Page 13

      Business Day following the applicable Valuation Date, then the Calculation
      Agent shall determine the Market Value for such Valuation Date in its
      reasonable discretion;

      "Quotation Method":

            [Mid-market means that only the arithmetic mean of the bid and offer
            quotations provided by Dealers that have provided both bid and offer
            quotations shall be used in the calculation of Market Value.];

      "Reference Obligation" means the obligation(s) as follows:

      Issuer/Borrower:              [                     ]
      Guarantor:                    [                     ]
      Maturity:                     [                     ]

      Original Issue Amount:        [                     ]
      Initial Price:                [                     ]
      Initial Spread:               [                     ];

      "Specified Indebtedness" means any obligation (whether present or future,
      contingent or otherwise, as principal or surety or otherwise in respect of
      money borrowed or raised or under any finance lease, redeemable preference

2.    The parties acknowledge that on the Effective Date of the Substitute
      Transaction or the Equivalent Transaction, Party A shall pay to the Credit
      Support Provider (in the case of the Substitute Transaction) or to the new
      Currency Swap Provider (in the case of the Equivalent Transaction) the
      amount equal to the amount (if a positive number) that hypothetically
      would have been payable by Party A to Party B under Section 6(e)(i)(3) if:

      (a)   the Transaction had been terminated;

      (b)   an Early Termination Date had occurred on the Effective Date; and

      (c)   Section 21 had not applied in respect of the Transaction.

      Any such amount shall be payable by Party A to the Credit Support Provider
      in accordance with the provisions of the relevant Master Agreement between
      Party A and the Credit Support Provider (in the case of the Substitute
      Transaction) or to the New Currency Swap Provider in accordance with the
      relevant Master Agreement between Party A and the New Currency Swap
      Provider (in the case of the Equivalent Transaction).

Each Transaction under this Confirmation shall be capable of being specified as
a Replaced Transaction in accordance with the provisions of Section 21 of the
Agreement. Those provisions shall apply as further specified below.

1.    Definitions for Credit Events

      "Calculation Agent" means the party to the Transaction (or a third party)
      designated as such for the Transaction. The Calculation Agent's
      calculations and determinations shall be made in good faith, in a
      commercially reasonable manner and be binding in the absence of manifest
      error [Credit Support Provider];

      "Initial Price" means, with respect to any Reference Obligation, the
      percentage listed with respect thereto in the definition of Reference
      Obligation herein as the Initial Price;

      "Interest Rate Adjustment Amount" means, with respect to any Reference
      Obligation, the absolute value of the difference between (i) the Mark to
      Market Value and (ii) 100% minus the Initial Price;

      "Mark to Market Value" means, in the determination of the Calculation
      Agent, with respect to any Reference Obligation, on any day, the mark to
      market value payable on that day (expressed as a percentage of the
      notional amount thereof), of a hypothetical interest rate swap commencing
      on the Effective Date between a hypothetical party ("Party X") and a
      counterparty with the highest long term senior debt rating of each Rating
      Agency, which swap has a notional amount equal to the Floating Rate Payer
      Calculation Amount and under which Party X (i) pays the Mark to Market
      Rate plus the Initial Spread and (ii) receives a fixed interest amount
      equal in 


                                                                          Page 5

      amount and timing to the coupons on the Reference Obligation. If, under
      such swap, Party X would be due to pay such mark to market value, Mark to
      Market Value will be negative and, if Party X would be due to receive such
      mark to market value, the Mark to Market Value will be positive.

      "Market Value" means, in accordance with the Quotation Method, the
      percentage equal to the arithmetic mean of quotations (exclusive of
      accrued but unpaid interest and expressed as a percentage) obtained from
      Dealers with respect to a Valuation Date in the manner provided below. In
      obtaining such price quotations from Dealers, the Calculation Agent will
      request each Dealer to provide firm bid and offer quotations for an
      aggregate amount of the Reference Obligation equal to the Quotation Amount
      to the extent reasonably practicable as of the Valuation Time on such
      Valuation Date. If more than three quotations are provided on such date,
      the Market Value shall be the arithmetic mean of such quotations without
      regard to the quotations having the highest and lowest values. If exactly
      three quotations are provided, the Market Value shall be the quotation
      remaining after disregarding the highest and lowest quotations. For this
      purpose, if more than one quotation has the same highest value or lowest
      value, then one of such quotations shall be disregarded. If exactly two
      quotations are provided, the Market Value shall be the arithmetic mean of
      such quotations. If fewer than two quotations are provided, then the
      Market Value shall be an amount as determined by the Calculation Agent on
      the next Business Day on which at least two quotations are provided by
      Dealers. If the Calculation Agent is unable to calculate the Market Value
      prior to the fifth Business Day following the applicable Valuation Date,
      then the Calculation Agent shall determine the Market Value for such
      Valuation Date in its reasonable discretion;

      "Quotation Method":

            [Bid means that only the bid quotations provided by Dealers shall be
            used in the calculation of Market Value] or

            [Offer means that only the offer quotations provided by Dealers
            shall be used in the calculation of Market Value.] or

            [Mid-market means that only the arithmetic mean of the bid and offer
            quotations provided by Dealers that have provided both bid and offer
            quotations shall be used in the calculation of Market Value.];

      "Reference Obligation" means the obligation(s) as follows:

      Issuer/Borrower:              [                     ]

                       Credit Support Provider Provisions

Each Transaction under this Confirmation shall be capable of being specified as
a Replaced Transaction in accordance with the provisions of Section 21 of the
Agreement. Those provisions shall apply as further specified below.

1.    Definitions for Credit Events

      "Calculation Agent" means the party to the Transaction (or a third party)
      designated as such for the Transaction. The Calculation Agent's
      calculations and determinations shall be made in good faith, in a
      commercially reasonable manner and be binding in the absence of manifest
      error [Credit Support Provider];

      "Initial Price" means, with respect to any Reference Obligation, the
      percentage listed with respect thereto in the definition of Reference
      Obligation herein as the Initial Price;

      "Interest Rate Adjustment Amount" means, with respect to any Reference
      Obligation, the absolute value of the difference between (i) the Mark to
      Market Value and (ii) 100% minus the Initial Price;

      "Mark to Market Value" means, in the determination of the Calculation
      Agent, with respect to any Reference Obligation, on any day, the mark to
      market value payable on that day (expressed as a percentage of the
      notional amount thereof), of a hypothetical interest rate swap commencing
      on the Effective Date between a hypothetical party ("Party X") and a
      counterparty with the highest long term senior debt rating of each Rating
      Agency, which swap has a notional amount equal to the Floating Rate Payer
      Calculation Amount and under which Party X (i) pays the Mark to Market
      Rate plus the Initial Spread and (ii) receives a fixed interest amount
      equal in amount and timing to the coupons on the Reference Obligation. If,
      under such swap, Party X would be due to pay such mark to market value,
      Mark to Market Value will be negative and, if Party X would be due to
      receive such mark to market value, the Mark to Market Value will be
      positive.

      "Market Value" means, in accordance with the Quotation Method, the
      percentage equal to the arithmetic mean of quotations (exclusive of
      accrued but unpaid interest and expressed as a percentage) obtained from
      Dealers with respect to a Valuation Date in the manner provided below. In
      obtaining such price quotations from Dealers, the Calculation Agent will
      request each Dealer to provide firm bid and offer quotations for an
      aggregate amount of the Reference Obligation equal to the Quotation Amount
      to the extent reasonably practicable as of the Valuation Time on such
      Valuation Date. If more than three quotations are provided on such date,
      the Market Value shall be the arithmetic mean of such quotations without
      regard to the quotations having the highest and lowest values. If exactly
      three quotations are provided, the Market Value shall be the quotation
      remaining after disregarding the highest and lowest quotations. For this
      purpose, if more than one quotation has the same highest value or lowest
      value, then one of such quotations shall be disregarded. If exactly two
      quotations are provided, the Market Value shall be the arithmetic mean of
      such quotations. If fewer than two quotations are provided, then the
      Market Value shall be an amount as determined by the Calculation Agent on
      the next Business Day on which at least two quotations are provided by
      Dealers. If the Calculation Agent is unable to calculate the Market Value
      prior to the fifth


                                                                         Page 13

      Business Day following the applicable Valuation Date, then the Calculation
      Agent shall determine the Market Value for such Valuation Date in its
      reasonable discretion;

      "Quotation Method":

            [Mid-market means that only the arithmetic mean of the bid and offer
            quotations provided by Dealers that have provided both bid and offer
            quotations shall be used in the calculation of Market Value.];

      "Reference Obligation" means the obligation(s) as follows:

      Issuer/Borrower:                    [              ]
      Guarantor:                          [              ]
      Maturity:                           [              ]

      Original Issue Amount:              [              ]
      Initial Price:                      [              ]
      Initial Spread:                     [              ];

      "Specified Indebtedness" means any obligation (whether present or future,
      contingent or otherwise, as principal or surety or otherwise in respect of
      money borrowed or raised or under any finance lease, redeemable preference

      transaction of a type described in the last 6 lines of the definition of
      Specified Transaction.

      "Threshold Amount" means [US$25,000,000]

      "Valuation Time" - [                ]

2.    The parties acknowledge that on the Effective Date of the Substitute
      Transaction or the Equivalent Transaction, Party A shall pay to the Credit
      Support Provider (in the case of the Substitute Transaction) or to the new
      Currency Swap Provider (in the case of the Equivalent Transaction) the
      amount equal to the amount (if a positive number) that hypothetically
      would have been payable by Party A to Party B under Section 6(e)(i)(3) if:

      (a)   the Transaction had been terminated;

      (b)   an Early Termination Date had occurred on the Effective Date; and

      (c)   Section 21 had not applied in respect of the Transaction.

      Any such amount shall be payable by Party A to the Credit Support Provider
      in accordance with the provisions of the relevant Master Agreement between
      Party A and the Credit Support Provider (in the case of the Substitute
      Transaction) or to the New Currency Swap Provider in accordance with the
      relevant Master Agreement between Party A and the New Currency Swap
      Provider (in the case of the Equivalent Transaction).

Each Transaction under this Confirmation shall be capable of being specified as
a Replaced Transaction in accordance with the provisions of Section 21 of the
Agreement. Those provisions shall apply as further specified below.

1.    Definitions for Credit Events

      "Calculation Agent" means the party to the Transaction (or a third party)
      designated as such for the Transaction. The Calculation Agent's
      calculations and determinations shall be made in good faith, in a
      commercially reasonable manner and be binding in the absence of manifest
      error [Credit Support Provider];

      "Initial Price" means, with respect to any Reference Obligation, the
      percentage listed with respect thereto in the definition of Reference
      Obligation herein as the Initial Price;

      "Interest Rate Adjustment Amount" means, with respect to any Reference
      Obligation, the absolute value of the difference between (i) the Mark to
      Market Value and (ii) 100% minus the Initial Price;

      "Mark to Market Value" means, in the determination of the Calculation
      Agent, with respect to any Reference Obligation, on any day, the mark to
      market value payable on that day (expressed as a percentage of the
      notional amount thereof), of a hypothetical interest rate swap commencing
      on the Effective Date between a hypothetical party ("Party X") and a
      counterparty with the highest long term senior debt rating of each Rating
      Agency, which swap has a notional amount equal to the Floating Rate Payer
      Calculation Amount and under which Party X (i) pays the Mark to Market
      Rate plus the Initial Spread and (ii) receives a fixed interest amount
      equal in


                                                                          Page 5

                                                     WESTPAC BANKING CORPORATION

      amount and timing to the coupons on the Reference Obligation. If, under
      such swap, Party X would be due to pay such mark to market value, Mark to
      Market Value will be negative and, if Party X would be due to receive such
      mark to market value, the Mark to Market Value will be positive.

      "Market Value" means, in accordance with the Quotation Method, the
      percentage equal to the arithmetic mean of quotations (exclusive of
      accrued but unpaid interest and expressed as a percentage) obtained from
      Dealers with respect to a Valuation Date in the manner provided below. In
      obtaining such price quotations from Dealers, the Calculation Agent will
      request each Dealer to provide firm bid and offer quotations for an
      aggregate amount of the Reference Obligation equal to the Quotation Amount
      to the extent reasonably practicable as of the Valuation Time on such
      Valuation Date. If more than three quotations are provided on such date,
      the Market Value shall be the arithmetic mean of such quotations without
      regard to the quotations having the highest and lowest values. If exactly
      three quotations are provided, the Market Value shall be the quotation
      remaining after disregarding the highest and lowest quotations. For this
      purpose, if more than one quotation has the same highest value or lowest
      value, then one of such quotations shall be disregarded. If exactly two
      quotations are provided, the Market Value shall be the arithmetic mean of
      such quotations. If fewer than two quotations are provided, then the
      Market Value shall be an amount as determined by the Calculation Agent on
      the next Business Day on which at least two quotations are provided by
      Dealers. If the Calculation Agent is unable to calculate the Market Value
      prior to the fifth Business Day following the applicable Valuation Date,
      then the Calculation Agent shall determine the Market Value for such
      Valuation Date in its reasonable discretion;

                                MASTER AGREEMENT

                            dated as of __ June 1997

Morgan Guaranty Trust Company      Westpac Securities Administration Limited
of New York, London Office         (ACN 000 049 472) in its capacity as
                                   trustee of the Series 1998-1G WST Trust and
                                   the other parties shown on page 18 of this 
                                   agreement

- ------------------------------ and ---------------------------------------------
have entered and/or anticipate entering into one or more transactions (each a
"Transaction") that are or will be governed by this Master Agreement, which
includes the schedule (the "Schedule"), and the documents and other confirming
evidence (each a "Confirmation") exchanged between the parties confirming those
Transactions.

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 other provisions of this Master Agreement, the Schedule
will prevail. In the event of any inconsistency between the provisions of any
Confirmation and this Master Agreement (including the Schedule), such
Confirmation will prevail for the purpose of the relevant Transaction.

(c) Single Agreement. All Transactions are entered into in reliance on the fact
that this Master Agreement and all Confirmations form a single agreement between
the parties (collectively referred to as this "Agreement"), and the parties
would not otherwise enter into any Transactions.

2. Obligations

(a) General Conditions.

      (i) Each party will make each payment or delivery specified in each
      Confirmation to be made by it, subject to the other provisions of this
      Agreement.

      (ii) Payments under this Agreement will be made on the due date for value
      on that date in the place of the account specified in the relevant
      Confirmation or otherwise pursuant to this Agreement, in freely
      transferable funds and in the manner customary for payments in the
      required currency. Where settlement is by delivery (that is, other than by
      payment), such delivery will be made for receipt on the due date in the
      manner customary for the relevant obligation unless otherwise specified in
      the relevant Confirmation or elsewhere in this Agreement.

      (iii) Each obligation of each party under Section 2(a)(i) is subject to
      (1) the condition precedent that no Event of Default or Potential Event of
      Default with respect to the other party has occurred and is continuing,
      (2) the condition precedent that no Early Termination Date in respect of
      the relevant Transaction has occurred or been effectively designated and
      (3) each other applicable condition precedent specified in this Agreement.


<PAGE>

(b) Change of Account. Either party may change its account for receiving a
payment or delivery by giving notice to the other party at least five Local
Business Days prior to the scheduled date for the payment or delivery to which
such change applies unless such other party gives timely notice of a reasonable
objection to such change.

(c) Netting. If on any date amounts would otherwise be payable: --

      (i) in the same currency; and

      (ii) in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to make
payment or any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount
will be determined in respect of all amounts payable on the same date in the
same currency in respect of such Transactions, regardless of whether such
amounts are payable in respect of the same Transaction. The election may be made
in the Schedule or a Confirmation by specifying that subparagraph (ii) above
will not apply to the Transactions identified as being subject to the election,
together with the starting date (in which case subparagraph (ii) above will not,
or will cease to, apply to such Transactions from such date). This election may
be made separately for different groups of Transactions and will apply
separately to each pairing of Offices through which the parties make and receive
payments or deliveries.

(d) Deduction or Withholding for Tax.

      (i) Gross-Up. All payments under this Agreement will be made without any
      deduction or withholding for or on account of any Tax unless such
      deduction or withholding is required by any applicable law, as modified by
      the practice of any relevant governmental revenue authority, then in
      effect. If a party is so required to deduct or withhold, then that party
      ("X") will: --

            (1) promptly notify the other party ("Y") of such requirement;

            (2) pay to the relevant authorities the full amount required to be
            deducted or withheld (including the full amount required to be
            deducted or withheld from any additional amount paid by X to Y under
            this Section 2(d)) promptly upon the earlier of determining that
            such deduction or withholding is required or receiving notice that
            such amount has been assessed against Y;

            (3) promptly forward to Y an official receipt (or a certified copy),
            or other documentation reasonably acceptable to Y, evidencing such
            payment to such authorities; and

            (4) if such Tax is an Identifiable Tax, pay to Y, in addition to the
            payment to which Y is otherwise entitled under this Agreement, such
            additional amount as is necessary to ensure that the net amount
            actually received by Y (free and clear of Indemnifiable Taxes,
            whether assessed against X or Y) will equal the full amount Y would
            have received had no such deduction or withholding been required.
            However, X will not be required to pay any additional amount to Y to
            the extent that it would not be required to be paid but for: --

                  (A) the failure by Y to comply with or perform any agreement
                  contained in Section 4(a)(i), 4(a)(iii) or 4(d); or

                  (B) the failure of a representation made by Y pursuant to
                  Section 3(f) to be accurate and true unless such failure would
                  not have occurred but for (I) any action taken by a taxing
                  authority, or brought in a court of competent jurisdiction, on
                  or after the date on which a Transaction is entered into
                  (regardless of whether such action is taken or brought with
                  respect to a party to this Agreement) or (II) a Change in Tax
                  Law.


                                       2
<PAGE>

      (ii) Liability. if: --

            (1) X is required by any applicable law, as modified by the practice
            of any relevant governmental revenue authority, to make any
            deduction or withholding in respect of which X would not be required
            to pay an additional amount to Y under Section 2(d)(i)(4);

            (2) X does not so deduct or withhold; and
 
            (3) a liability resulting from such Tax is assessed directly against
            X,

      then, except to the extent Y has satisfied or then satisfies the liability
      resulting from such Tax, Y will promptly pay to X the amount of such
      liability (including any related liability for interest, but including any
      related liability for penalties only if Y has failed to comply with or
      perform any agreement contained in Section 4(a)(i), 4(a)(iii) or 4(d)).

(e) Default Interest; Other Amounts. Prior to the occurrence or effective
designation of an Early Termination Date in respect of the relevant Transaction,
a party that defaults in the performance of any payment obligation will, to the
extent permitted by law and subject to Section 6(c), be required to pay interest
(before as well as after judgement) on the overdue amount to the other party on
demand in the same currency as such overdue amount, for the period from (and
including) the original due date for payment to (but excluding) the date of
actual payment, at the Default Rate. Such interest will be calculated on the
basis of daily compounding and the actual number of days elapsed. If, prior to
the occurrence or effective designation of an Early Termination Date in respect
of the relevant Transaction, a party defaults in the performance of any
obligation required to be settled by delivery, it will compensate the other
party on demand if and to the extent provided for in the relevant Confirmation
or elsewhere in this Agreement.

3. Representations

Each party represents to the other party (which representations will be deemed
to be repeated by each party on each date on which a Transaction is entered into
and, in the case of the representations in Section 3(f), at all times until the
termination of this Agreement) that: --

(a) Basic Representations.

      (i) Status. It is duly organised and validly existing under the laws of
      the jurisdiction of its organsiation or incorporation and, if relevant

      documentation relating to this Agreement to which it is a party, to

      its obligations under this Agreement and any obligations it has under any
      Credit Support Document to which it is a party and has taken all necessary
      action to authorise such execution, delivery and performance;

      (iii) No Violation or Conflict. Such execution, delivery and performance
      do not violate or conflict with any law applicable to it, any provision of

      agency of government applicable to it or any of its assets or any
      contractual restriction binding on or affecting it or any of its assets;

      (iv) Consents. All governmental and other consents that are required to
      have been obtained by it with respect to this Agreement or any Credit

      force and effect and all conditions of any such consents have been
      complied with; and

      (v) Obligations Binding. Its obligations under this Agreement and any
      Credit Support Document to which it is a party constitute its legal, valid
      and binding obligations, enforceable in accordance with their respective
      terms (subject to applicable bankruptcy, reorganisation, insolvency,
      moratorium or similar laws affecting creditors' rights generally and
      subject, as to enforceability, to equitable principles of general
      application (regardless of whether enforcement is sought in a proceeding
      in equity or at law)).

against it of this Agreement or any Credit Support Document to which it is a
party or its ability to perform its obligations under this Agreement or such
Credit Support Document.

      the Schedule or any Confirmation;

      (ii) any other documents specified in the Schedule or any Confirmation;
      and

      that may be required or reasonably requested in writing in order to allow
      such other party or its Credit Support Provider to make a payment under
      this Agreement or any applicable Credit Support Document without any
      deduction or withholding for or on account of any Tax or with such
      deduction or withholding at a reduced rate (so long as the completion,
      execution or submission of such form or document would not materially
      prejudice the legal or commercial position of the party in receipt of such
      demand), with any such form or document to be accurate and completed in a
      manner reasonably satisfactory to such other party and to be executed and
      to be delivered with any reasonably required certification,

in each case by the date specified in the Schedule or such Confirmation or, if

branch or office through which it is acting for the purpose of this Agreement is
located ("Stamp Tax Jurisdiction") and will indemnify the other party against
any Stamp Tax levied or imposed upon the other part or in respect of the other
party's execution or performance of this Agreement by any such Stamp Tax
Jurisdiction which is not also a Stamp Tax Jurisdiction with respect to the
other party.

      party;

      (ii) Breach of Agreement. Failure by the party to comply with or perform

      notice of a Termination Event or any agreement or obligation under Section
      4(a)(i), 4(a)(iii) or 4(d)) to be complied with or performed by the party

      party;

      (iii) Credit Support Default.

            (1) Failure by the party or any Credit Support Provider of such
            party to comply with or perform any agreement or obligation to be

            Support Document if such failure is continuing after any applicable
            grace period has elapsed;

            (2) the expiration or termination of such Credit Support Document or
            the failing or ceasing of such Credit Support Document to be in full
            force and effect for the purpose of this Agreement (in either case
            other than in accordance with its terms) prior to the satisfaction
            of all obligations of such party under each Transaction to which
            such Credit Support Document relates without the written consent of
            the other party; or

            (3) the party or such Credit Support Provider disaffirms, disclaims,
            repudiates or rejects, in whole or in part, or challenges the
            validity of, such Credit Support Document;

      (iv) Misrepresentation. A representation (other than a representation
      under Section 3(e) or (f)) made or repeated or deemed to have been made or

      misleading in any material respect when made or repeated or deemed to have
      been made or repeated;

      (v) Default under Specified Transaction. The party, any Credit Support
      Provider of such party or any applicable Specified Entity of such party

      of, an acceleration of obligations under, or an early termination of, that
      Specified Transaction, (2) defaults, after giving effect to any applicable
      notice requirement or grace period, in making any payment or delivery due
      on the last payment delivery or exchange date of, or any payment on early
      termination of, a Specified Transaction (or such default continues for at
      least three Local Business Days if there is no applicable notice
      requirement or grace period) or (3) disaffirms, disclaims, repudiates or
      rejects, in whole or in part, a Specified Transaction (or such action is
      taken by any person or entity appointed or empowered to operate it or act
      on its behalf);

      (vi) Cross Default. If "Cross Default" is specified in the Schedule as
      applying to the party, the occurrence or existence of (1) a default, event
      of default or other similar condition or event (however


                                       5
<PAGE>

      described) in respect of such party, any Credit Support Provider of such
      party or any applicable Specified Entity of such party under one or more
      agreements or instruments relating to Specified Indebtedness of any of
      them (individually or collectively) in an aggregate amount of not less
      than the applicable Threshold Amount (as specified in the Schedule) which
      has resulted in such Specified Indebtedness becoming, or becoming capable
      at such time of being declared, due and payable under such agreements or
      instruments, before it would otherwise have been due and payable or (2) a
      default by such party, such Credit Support Provider or such Specified
      Entity (individually or collectively) in making one or more payments on
      the due date thereof in an aggregate amount of not less than the
      applicable Threshold Amount under such agreements or instruments (after
      giving effect to any applicable notice requirement or grace period);

      (vii) Bankruptcy. The party, any Credit Support Provider of such party or
      any applicable Specified Entity of such party: --

            (1) is dissolved (other than pursuant to a consolidation,
            amalgamation or merger); (2) becomes insolvent or is unable to pay
            its debts or fails or admits in writing its inability generally to
            pay its debts as they become due; (3) makes a general assignment,
            arrangement or composition with or for the benefit of its creditors;
            (4) institutes or has instituted against it a proceeding seeking a
            judgement of insolvency or bankruptcy or any other relief under any
            bankruptcy or insolvency law or other similar law affecting
            creditors' rights, or a petition is presented for its winding-up or
            liquidation, and, in the case of any such proceeding or petition
            instituted or presented against it, such proceeding or petition (A)
            results in a judgement of insolvency or bankruptcy or the entry of
            an order for relief or the making of an order for its winding-up or
            liquidation or (B) is not dismissed, discharged, stayed or
            restrained in each case within 30 days of the institution or
            presentation thereof; (5) has a resolution passed for its
            winding-up, official management or liquidation (other than pursuant
            to a consolidation, amalgamation or merger); (6) seeks or becomes
            subject to the appointment of an administrator, provisional
            liquidator, conservator, receiver, trustee, custodian or other
            similar official for it or for all or substantially all its assets;
            (7) has a secured party take possession of all or substantially all
            its assets or has a distress, execution, attachment, sequestration
            or other legal process levied, enforced or sued on or against all or
            substantially all its assets and such secured party maintains
            possession, or any such process is not dismissed, discharged, stayed
            or restrained, in each case within 30 days thereafter; (8) causes or
            is subject to any event with respect to it which, under the
            applicable laws of any jurisdiction, has an analogous effect to any
            of the events specified in clauses (1) to (7) (inclusive); or (9)
            takes any action in furtherance of, or indicating its consent to,
            approval of, or acquiescence in, any of the foregoing acts; or

      (viii) Merger Without Assumption. The party or any Credit Support Provider
      of such party consolidates or amalgamates with, or merges with or into, or
      transfers all or substantially all its assets to, another entity and, at
      the time of such consolidation, amalgamation, merger or transfer: --

            (1) the resulting, surviving or transferee entity fails to assume
            all the obligations of such party or such Credit Support Provider
            under this Agreement or any Credit Support Document to which it or
            its predecessor was a party by operation of law or pursuant to an
            agreement reasonably satisfactory to the other party to this
            Agreement; or

            (2) the benefits of any Credit Support Document fail to extend
            (without the consent of the other party) to the performance by such
            resulting, surviving or transferee entity of its obligations under
            this Agreement.

(b) Termination Events. The occurrence at any time with respect to a party or,
if applicable, any Credit Support Provider of such party or any Specified Entity
of such party of any event specified below constitutes an Illegality if the
event is specified in (i) below, a Tax Event if the event is specified in (ii)
below or a Tax Event Upon Merger if the event is specified in (iii) below, and,
if specified to be applicable, a Credit Event


                                       6
<PAGE>

Upon Merger if the event is specified pursuant to (iv) below or an Additional
Termination Event if the event is specified pursuant to (v) below: --

      (i) Illegality. Due to the adoption of, or any change in, any applicable
      law after the date on which a Transaction is entered into, or due to the
      promulgation of, or any change in, the interpretation by any court,
      tribunal or regulatory authority with competent jurisdiction of any
      applicable law after such date, it becomes unlawful (other than as a
      result of a breach by the party of Section 4(b)) for such party (which
      will be the Affected Party): --

            (1) to perform any absolute or contingent obligation to make a
            payment or delivery or to receive a payment or delivery in respect
            of such Transaction or to comply with any other material provision
            of this Agreement relating to such Transaction; or

            (2) to perform, or for any Credit Support Provider of such party to
            perform, any contingent or other obligation which the party (or such
            Credit Support Provider) has under any Credit Support Document
            relating to such Transaction;

      (ii) Tax Event. Due to (x) any action taken by a taxing authority, or
      brought in a court of competent jurisdiction, on or after the date on
      which a Transaction is entered into (regardless of whether such action is
      taken or brought with respect to a party to this Agreement) or (y) a
      Change in Tax Law, the party (which will be the Affected Party) will, or
      there is a substantial likelihood that it will, on the next succeeding
      Scheduled Payment Date (1) be required to pay to the other party an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount is required to be
      deducted or withheld for or on account of a Tax (except in respect of
      interest under Section 2(e), 6(d)(ii) or 6(e)) and no additional amount is
      required to be paid in respect of such Tax under Section 2(d)(i)(4) (other
      than by reason of Section 2(d)(i)(4)(A) or (B));

      (iii) Tax Event Upon Merger. The party (the "Burdened Party") on the next
      succeeding Scheduled Payment Date will either (1) be required to pay an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount has been deducted or
      withheld for or on account of any Indemnifiable Tax in respect of which
      the other party is not required to pay an additional amount (other than by
      reason of Section 2(d)(i)(4)(A) or (B)), in either case as a result of a
      party consolidating or amalgamating with, or merging with or into, or
      transferring all or substantially all its assets to, another entity (which
      will be the Affected Party) where such action does not constitute an event
      described in Section 5(a)(viii);

      (iv) Credit Event Upon Merger. If "Credit Event Upon Merger" is specified
      in the Schedule as applying to the party, such party ("X"), any Credit
      Support Provider of X or any applicable Specified Entity of X consolidates
      or amalgamates with, or merges with or into, or transfers all or
      substantially all its assets to, another entity and such action does not
      constitute an event described in Section 5(a)(viii) but the
      creditworthiness of the resulting, surviving or transferee entity is
      materially weaker than that of X, such Credit Support Provider or such
      Specified Entity, as the case may be, immediately prior to such action
      (and, in such event, X or its successor or transferee, as appropriate,
      will be the Affected Party); or

      (v) Additional Termination Event. If any "Additional Termination Event" is
      specified in the Schedule or any Confirmation as applying, the occurrence
      of such event (and, in such event, the Affected Party or Affected Parties
      shall be as specified for such Additional Termination Event in the
      Schedule or such Confirmation).

(c) Event of Default and Illegality. If an event or circumstance which would
otherwise constitute or give rise to an Event of Default also constitutes an
Illegality, it will be treated as an Illegality and will not constitute an Event
of Default.


                                       7

6. Early Termination

(a) Right to Terminate Following Event of Default. If at any time an Event of
Default with respect to a party (the "Defaulting Party") has occurred and is
then continuing, the other party (the "Non-defaulting Party") may, by not more
than 20 days notice to the Defaulting Party specifying the relevant Event of
Default designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however,
"Automatic Early Termination" is specified in the Schedule as applying to a
party, then an Early Termination Date in respect of all outstanding Transactions
will occur immediately upon the occurrence with respect to such party of an
Event of Default specified in Section 5(a)(vii)(1), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the
institution of the relevant proceeding or the presentation of the relevant
petition upon the occurrence with respect to such party of an Event of Default
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b) Right to Terminate Following Termination Event.

      (i) Notice. If a Termination Event occurs, an Affected Party will,
      promptly upon becoming aware of it, notify the other party, specifying the
      nature of that Termination Event and each Affected Transaction and will
      also give such other information about that Termination Event as the other
      party may reasonably require.

      (ii) Transfer to Avoid Termination Event. If either an Illegality under
      Section 5(b)(i)(1) or a Tax Event occurs and there is only one Affected
      Party, or if a Tax Event Upon Merger occurs and the Burdened Party is the
      Affected Party, the Affected Party will, as a condition to its right to
      designate an Early Termination Date under Section 6(b)(iv), use all
      reasonable efforts (which will not require such party to incur a loss,
      excluding immaterial, incidental expenses) to transfer within 20 days
      after it gives notice under Section 6(b)(i) all its rights and obligations
      under this Agreement in respect of the Affected Transactions to another of
      its Offices or Affiliates so that such Termination Event ceases to exist.

      If the Affected Party is not able to make such a transfer it will give
      notice to the other party to that effect within such 20 day period,
      whereupon the other party may effect such a transfer within 30 days after
      the notice is given under Section 6(b)(i).

      Any such transfer by a party under this Section 6(b)(ii) will be subject
      to and conditional upon the prior written consent of the other party,
      which consent will not be withheld if such other party's policies in
      effect at such time would permit it to enter into transactions with the
      transferee on the terms proposed.

      (iii) Two Affected Parties. If an Illegality under Section 5(b)(i)(1) or a
      Tax Event occurs and there are two Affected Parties, each party will use
      all reasonable efforts to reach agreement within 30 days after notice
      thereof is given under Section 6(b)(i) on action to avoid that Termination
      Event.

      (iv) Right to Terminate. If: --

            (1) a transfer under Section 6(b)(ii) or an agreement under Section
            6(b)(iii), as the case may be, has not been effected with respect to
            all Affected Transactions within 30 days after an Affected Party
            gives notice under Section 6(b)(i); or

            (2) an Illegality under Section 5(b)(i)(2), a Credit Event Upon
            Merger or an Additional Termination Event occurs, or a Tax Event
            Upon Merger occurs and the Burdened Party is not the Affected Party,

      either party in the case of an Illegality, the Burdened Party in the case
      of a Tax Event Upon Merger, any Affected Party in the case of a Tax Event
      or an Additional Termination Event if there is more than one Affected
      Party, or the party which is not the Affected Party in the case of a
      Credit Event Upon Merger or an Additional Termination Event if there is
      only one Affected Party may, by not more than 20 days notice to the other
      party and provided that the relevant Termination Event is then


                                       8
<PAGE>

      continuing, designate a day not earlier than the day such notice is
      effective as an Early Termination Date in respect of all Affected
      Transactions.

(c) Effect of Designation.

      (i) If notice designating an Early Termination Date is given under Section
      6(a) or (b), the Early Termination Date will occur on the date so
      designated, whether or not the relevant Event of Default or Termination
      Event is then continuing.

      (ii) Upon the occurrence of effective designation of an Early Termination
      Date, no further payments or deliveries under Section 2(a)(i) or 2(e) in
      respect of the Terminated Transactions will be required to be made, but
      without prejudice to the other provisions of this Agreement. The amount,
      if any, payable in respect of an Early Termination Date shall be
      determined pursuant to Section 6(e).

(d) Calculations.

      (i) Statement. On or as soon as reasonably practicable following the
      occurrence of an Early Termination Date, each party will make the
      calculations on its part, if any, contemplated by Section 6(e) and will
      provide to the other party a statement (1) showing, in reasonable detail,
      such calculations (including all relevant quotations and specifying any
      amount payable under Section 6(e)) and (2) giving details of the relevant
      account to which any amount payable to it is to be paid. In the absence of
      written confirmation from the source of a quotation obtained in
      determining a Market Quotation, the records of the party obtaining such
      quotation will be conclusive evidence of the existence and accuracy of
      such quotation.

      (ii) Payment Date. An amount calculated as being due in respect of any
      Early Termination Date under Section 6(e) will be payable on the day that
      notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated or occurs as a result of an Event of
      Default) and on the day which is two Local Business Days after the day on
      which notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated as a result of a Termination Event).
      Such amount will be paid together with (to the extent permitted under
      applicable law) interest thereon (before as well as after judgment) in
      the Termination Currency, from (and including) the relevant Early
      Termination Date to (but excluding) the date such amount is paid, at the
      Applicable Rate. Such interest will be calculated on the basis of daily
      compounding and the actual number of days elapsed.

(e) Payments on Early Termination. If an Early Termination Date occurs, the
following provisions shall apply based on the parties' election in the Schedule
of a payment measure, either "Market Quotation" or "Loss", and a payment method,
either the "First Method" or the "Second Method". If the parties fail to
designate a payment measure or payment method in the Schedule, it will be deemed
that "Market Quotation" or the "Second Method", as the case may be, shall apply.
The amount, if any, payable in respect of an Early Termination Date and
determined pursuant to this Section will be subject to any Set-off.

      (i) Events of Default. If the Early Termination Date results from an Event
      of Default: --

            (1) First Method and Market Quotation. If the First Method and
            Market Quotation apply, the Defaulting Party will pay to the
            Non-defaulting Party the excess, if a positive number, of (A) the
            sum of the Settlement Amount (determined by the Non-defaulting
            Party) in respect of the Terminated Transactions and the Termination
            Currency Equivalent of the Unpaid Amounts owing to the
            Non-defaulting Party over (B) the Termination Currency Equivalent of
            the Unpaid Amounts owing to the Defaulting Party.

            (2) First Method and Loss. If the First Method and Loss apply, the
            Defaulting Party will pay to the Non-defaulting Party, if a positive
            number, the Non-defaulting Party's Loss in respect of this
            Agreement.

            (3) Second Method and Market Quotation. If the Second Method and
            Market Quotation apply, an amount will be payable equal to (A) the
            sum of the Settlement Amount (determined by the


                                       9
<PAGE>

            Non-defaulting Party) in respect of the Terminated Transactions and
            the Termination Currency Equivalent of the Unpaid Amounts owing to
            the Non-defaulting Party less (B) the Termination Currency
            Equivalent of the Unpaid Amounts owing to the Defaulting Party. If
            that amount is a positive number, the Defaulting Party will pay it
            to the Non-defaulting Party; if it is a negative number, the
            Non-defaulting Party will pay the absolute value of that amount to
            the Defaulting Party.

            (4) Second Method and Loss. If the Second Method and Loss apply, an
            amount will be payable equal to the Non-defaulting Party's Loss in
            respect of this Agreement. If that amount is a positive number, the
            Defaulting Party will pay it to the Non-defaulting Party; if it is a
            negative number, the Non-defaulting Party will pay the absolute
            value of that amount to the Defaulting Party.

      (iii) Termination Events. If the Early Termination Date results from a
      Termination Event: --

            (1) One Affected Party. If there is one Affected Party, the amount
            payable will be determined in accordance with Section 6(e)(i)(3), if
            Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
            except that, in either case, references to the Defaulting Party and
            to the Non-defaulting Party will be deemed to be references to the
            Affected Party and the party which is not the Affected Party,
            respectively, and, if Loss applies and fewer than all the
            Transactions are being terminated, Loss shall be calculated in
            respect of all Terminated Transactions.

            (2) Two Affected Parties. If there are two Affected Parties: --

                  (A) if Market Quotation applies, each party will determine a
                  Settlement Amount in respect of the Terminated Transactions,
                  and an amount will be payable equal to (I) the sum of (a)
                  one-half of the difference between the Settlement Amount of
                  the party with the higher Settlement Amount ("X") and the
                  Settlement Amount of the party with the lower Settlement
                  Amount ("Y") and (b) the Termination Currency Equivalent of
                  the Unpaid Amounts owing to X less (II) the Termination
                  Currency Equivalent of the Unpaid Amounts owing to Y; and

                  (B) if Loss applies, each party will determine its Loss in
                  respect of this Agreement (or, if fewer than all the
                  Transactions are being terminated, in respect of all
                  Terminated Transactions) and an amount will be payable equal
                  to one-half of the difference between the Loss of the party
                  with the higher Loss ("X") and the Loss of the party with the
                  lower Loss ("Y").

            If the amount payable is a positive number, Y will pay it to X; if
            it is a negative number, X will pay the absolute value of that
            amount to Y.

      (iii) Adjustment for Bankruptcy. In circumstances where an Early
      Termination Date occurs because "Automatic Early Termination" applies in
      respect of a party, the amount determined under this Section 6(e) will be
      subject to such adjustments as are appropriate and permitted by law to
      reflect any payments or deliveries made by one party to the other under
      this Agreement (and retained by such other party) during the period from
      the relevant Early Termination Date to the date for payment determined
      under Section 6(d)(ii).

      (iv) Pre-Estimate. The parties agree that if Market Quotation applies an
      amount recoverable under this Section 6(e) is a reasonable pre-estimate of
      loss and not a penalty. Such amount is payable for the loss of bargain and
      the loss of protection against future risks and except as otherwise
      provided in this Agreement neither party will be entitled to recover any
      additional damages as a consequence of such losses.


                                       10

7. Transfer

Subject to Section 6(b)(ii), neither this Agreement nor any interest or
obligation in or under this Agreement may be transferred (whether by way of
security or otherwise) by either party without the prior written consent of the
other party, except that: --

(a) a party may make such a transfer of this Agreement pursuant to a
consolidation or amalgamation with, or merger with or into, or transfer of all
or substantially all its assets to, another entity (but without prejudice to any
other right or remedy under this Agreement); and

(b) a party may make such a transfer of all or any part of its interest in any
amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void.

8. Contractual Currency

(a) Payment in the Contractual Currency. Each payment under this Agreement will
be made in the relevant currency specified in this Agreement for that payment
(the "Contractual Currency"). To the extent permitted by applicable law, any
obligation to make payments under this Agreement in the Contractual Currency
will not be discharged or satisfied by any tender in any currency other than the
Contractual Currency, except to the extent such tender results in the actual
receipt by the party to which payment is owed, acting in a reasonable manner and
in good faith in converting the currency so tendered into the Contractual
Currency, of the full amount in the Contractual Currency of all amounts payable
in respect of this Agreement. If for any reason the amount in the Contractual
Currency so received falls short of the amount in the Contractual Currency
payable in respect of this Agreement, the party required to make the payment
will, to the extent permitted by applicable law, immediately pay such additional
amount in the Contractual Currency as may be necessary to compensate for the
shortfall. If for any reason the amount in the Contractual Currency so received
exceeds the amount in the Contractual Currency payable in respect of this
Agreement, the party receiving the payment will refund promptly the amount of
such excess.

(b) Judgments. To the extent permitted by applicable law, if any judgment or
order expressed in a currency other than the Contractual Currency is rendered
(i) for the payment of any amount owing in respect of this Agreement, (ii) for
the payment of any amount relating to any early termination in respect of this
Agreement or (iii) in respect of a judgment or order of another court for the
payment of any amount described in (i) or (ii) above, the party seeking
recovery, after recovery in full of the aggregate amount to which such party is
entitled pursuant to the judgment or order, will be entitled to receive
immediately from the other party the amount of any shortfall of the Contractual
Currency received by such party as a consequence of sums paid in such other
currency and will refund promptly to the other party any excess of the
Contractual Currency received by such party as a consequence of sums paid in
such other currency if such shortfall or such excess arises or results from any
variation between the rate of exchange at which the Contractual Currency is
converted into the currency of the judgment or order for the purposes of such
judgment or order and the rate of exchange at which such party is able, acting
in a reasonable manner and in good faith in converting the currency received
into the Contractual Currency, to purchase the Contractual Currency with the
amount of the currency of the judgment or order actually received by such party.
The term "rate of exchange" includes, without limitation, any premiums and costs
of exchange payable in connection with the purchase of or conversion into the
Contractual Currency.

(c) Separate Indemnities. To the extent permitted by applicable law, these
indemnities constitute separate and independent obligations from the other
obligations in this Agreement, will be enforceable as separate and independent
causes of action, will apply notwithstanding any indulgence granted by the party
to which any payment is owed and will not be affected by judgment being obtained
or claim or proof being made for any other sums payable in respect of this
Agreement.

(d) Evidence of Loss. For the purpose of this Section 8, it will be sufficient
for a party to demonstrate that it would have suffered a loss had an actual
exchange or purchase been made.


                                       11

9. Miscellaneous

(a) Entire Agreement. This Agreement constitutes the entire agreement and
understanding of the parties with respect to its subject matter and supersedes
all oral communication and prior writings with respect thereto.

(b) Amendments. No amendment, modification or waiver in respect of this
Agreement will be effective unless in writing (including a writing evidenced by
a facsimile transmission) and executed by each of the parties or confirmed by an
exchange of telexes or electronic messages on an electronic messaging system.

(c) Survival of Obligations. Without prejudice to Sections 2(a)(iii) and
6(c)(ii), the obligations of the parties under this Agreement will survive the
termination of any Transaction.

(d) Remedies Cumulative. Except as provided in this Agreement, the rights,
powers, remedies and privileges provided in this Agreement are cumulative and
not exclusive of any rights, powers, remedies and privileges provided by law.

(e) Counterparts and Confirmations.

      (i) This Agreement (and each amendment, modification and waiver in respect
      of it) may be executed and delivered in counterparts (including by
      facsimile transmission), each of which will be deemed an original.

      (ii) The parties intend that they are legally bound by the terms of each
      Transaction from the moment they agree to those terms (whether orally or
      otherwise). A Confirmation shall be entered into as soon as practicable
      and may be executed and delivered in counterparts (including by facsimile
      transmission) or be created by an exchange of telexes or by an exchange of
      electronic messages on an electronic messaging system, which in each case
      will be sufficient for all purposes to evidence a binding supplement to
      this Agreement. The parties will specify therein or through another
      effective means that any such counterpart, telex or electronic message
      constitutes a Confirmation.

(f) No Waiver of Rights. A failure or delay in exercising any right, power or
privilege in respect of this Agreement will not be presumed to operate as a
waiver, and a single or partial exercise of any right, power or privilege will
not be presumed to preclude any subsequent or further exercise of that right,
power or privilege or the exercise of any other right, power or privilege.

(g) Headings. The headings used in this Agreement are for convenience of
reference only and are not to affect the construction of or to be taken into
consideration in interpreting this Agreement.

10. Offices; Multibranch Parties

(a) If Section 10(a) is specified in the Schedule as applying, each party that
enters into a Transaction through an Office other than its head or home office
represents to the other party that, notwithstanding the place of booking office
or jurisdiction of incorporation or organisation of such party, the obligations
of such party are the same as if it had entered into the Transaction through its
head or home office. This representation will be deemed to be repeated by such
party on each date on which a Transaction is entered into.

(b) Neither party may change the Office through which it makes and receives
payments or deliveries for the purpose of Transaction without prior written
consent of the other party.

(c) If a party is specified as a Multibranch Party in the Schedule, such
Multibranch Party may make and receive payments or deliveries under any
Transaction through any Office listed in the Schedule, and the Office through
which it makes and receives payments or deliveries with respect to a Transaction
will be specified in the relevant Confirmation.

11. Expenses

A Defaulting Party will, on demand, indemnify and hold harmless the other party
for and against all reasonable out-of-pocket expenses, including legal fees and
Stamp Tax, incurred by such other party by reason of the enforcement and
protection of its rights under this Agreement or any Credit Support Document


                                       12
<PAGE>

to which the Defaulting Party is a party or by reason of the early termination
of any Transaction, including, but not limited to, costs of collection.

12. Notices

(a) Effectiveness. Any notice or other communication in respect of this
Agreement may be given in any manner set forth below (except that a notice or
other communication under Section 5 or 6 may not be given by facsimile
transmission or electronic messaging system) to the address or number or in
accordance with the electronic messaging system details provided (see the
Schedule) and will be deemed effective as indicated: --

      (i) if in writing and delivered in person or by courier, on the date it is
      delivered;

      (ii) if sent by telex, on the date the recipient's answerback is received;

      (iii) if sent by facsimile transmission, on the date that transmission is
      received by a responsible employee of the recipient in legible form (it
      being agreed that the burden of proving receipt will be on the sender and
      will not be met by a transmission report generated by the sender's
      facsimile machine);

      (iv) if sent by certified or registered mail (airmail, if overseas) or the
      equivalent (return receipt requested), on the date that mail is delivered
      or its delivery is attempted; or

      (v) if sent by electronic messaging system, on the date that electronic
      message is received,

unless the date of that delivery (or attempted delivery) or that receipt, as
applicable, is not a Local Business Day or that communication is delivered (or
attempted) or received, as applicable, after the close of business on a Local
Business Day, in which case that communication shall be deemed given and
effective on the first following day that is a Local Business Day.

(b) Change of Addresses. Either party may by notice to the other change the
address, telex or facsimile number or electronic messaging system details at
which notices or other communications are to be given to it.

13. Governing Law and Jurisdiction

(a) Governing Law. This Agreement will be governed by and construed in
accordance with the law specified an the Schedule.

(b) Jurisdiction. With respect to any suit, action or proceedings relating to
this Agreement ("Proceedings"), each party irrevocably: --

      (i) submits to the jurisdiction of the English courts, if this Agreement
      is expressed to be governed by English law, or to the non-exclusive
      jurisdiction of the courts of the State of New York and the United States
      District Court located in the Borough of Manhattan an New York City, if
      this Agreement is expressed to be governed by the laws of the State of New
      York; and

      (ii) waives any objection which it may have at any time to the laying of
      venue of any Proceedings brought in any such court, waives any claim that
      such Proceedings have been brought in an inconvenient forum and further
      waives the right to object, with respect to such Proceedings, that such
      court does not have any jurisdiction over such party.

Nothing in this Agreement precludes either party from bringing Proceedings in
any other jurisdiction (outside, if this Agreement is expressed to be governed
by English law, the Contracting States, as defined in Section 1(3) of the Civil
Jurisdiction and Judgments Act 1982 or any modification, extension or
re-enactment thereof for the time being in force) nor will the bringing of
Proceedings in any one or more jurisdictions preclude the bringing of
Proceedings in any other jurisdiction.

(c) Service of Process. Each party irrevocably appoints the Process Agent (if
any) specified opposite its name in the Schedule to receive, for it and on its
behalf, service of process in any Proceedings. If for any


                                       13
<PAGE>

reason any party's Process Agent is unable to act as such, such party will
promptly notify the other party and within 30 days appoint a substitute process
agent acceptable to the other party. The parties irrevocably consent to service
of process given in the manner provided for notices in Section 12. Nothing in
this Agreement will affect the right of either party to serve process in any
other manner permitted by law.

(d) Waiver of immunities. Each party irrevocably waives, to the fullest extent
permitted by applicable law, with respect to itself and its revenues and assets
(irrespective of their use or intended use), all immunity on the grounds of
sovereignty or other similar grounds from (i) suit, (ii) jurisdiction of any
court, (iii) relief by way of injunction, order for specific performance or for
recovery of property, (iv) attachment of its assets (whether before or after
judgment) and (v) execution or enforcement of any judgment to which it or its
revenues or assets might otherwise be entitled in any Proceedings in the courts
of any jurisdiction and irrevocably agrees, to the extent permitted by
applicable law, that it will not claim any such immunity in any Proceedings.

"Loss" means, with respect to this Agreement or one or more Terminated
Transactions, as the case may be, and a party, the Termination Currency
Equivalent of an amount that party reasonably determines in good faith to be its
total losses and costs (or gain, in which case expressed as a negative number)
in connection with this Agreement or that Terminated Transaction or group of
Terminated Transactions, as the case may be, including any loss of bargain, cost
of funding or, at the election of such party but without duplication, loss or
cost incurred as a result of its terminating, liquidating, obtaining or
reestablishing any hedge or related trading position (or any gain resulting from
any of them). Loss includes losses and costs (or gains) in respect of any
payment or delivery required to have been made (assuming satisfaction of each
applicable condition precedent) on or before the relevant Early Termination Date
and not made, except, so as to avoid duplication, if Section 6(e)(i)(1) or (3)
or 6(e)(ii)(2)(A) applies. Loss does not include a party's legal fees and
out-of-pocket expenses referred to under Section 11. A party will determine its

party may (but need not) determine its Loss by reference to quotations of
relevant rates or prices from one or more leading dealers in the relevant
markets.

"Market Quotation" means, with respect to one or more Terminated Transactions
and a party making the determination, an amount determined on the basis of
quotations from Reference Market-makers. Each quotation will be for an amount,
if any, that would be paid to such party (expressed as a negative number) or by
such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document
with respect to the obligations of such party) and the quoting Reference
Market-maker to enter into a transaction (the "Replacement Transaction") that
would have the effect of preserving for such party the economic equivalent of
any payment or delivery (whether the underlying obligation was absolute or
contingent and assuming the satisfaction of each applicable condition precedent)
by the parties under Section 2(a)(i) in respect of such Terminated Transaction
or group of Terminated Transactions that would, but for the occurrence of the
relevant Early Termination Date, have


                                       15
<PAGE>

been required after that date. For this purpose, Unpaid Amounts in respect of
the Terminated Transaction or group or Terminated Transactions are to be
excluded but, without limitation, any payment or delivery that would, but for
the relevant Early Termination Date, have been required (assuming satisfaction
of each applicable condition precedent) after that Early Termination Date is to
be included. The Replacement Transaction would be subject to such documentation
as such party and the Reference Market-maker may, in good faith, agree. The
party making the determination (or its agent) will request each Reference
Market-maker to provide its quotation to the extent reasonably practicable as of
the same day and time (without regard to different time zones) on or as soon as
reasonably practicable after the relevant Early Termination Date. The day and
time as of which those quotations are to be obtained will be selected in good
faith by the party obliged to make a determination under Section 6(e), and, if
each party is so obliged, after consultation with the other. If more than three
quotations are provided, the Market Quotation will be the arithmetic mean of the
quotations, without regard to the quotations having the highest and lowest
values. If exactly three such quotations are provided, the Market Quotation will
be the quotation remaining after disregarding the highest and lowest quotations.
For this purpose, if more than one quotation has the same highest value or
lowest value, then one of such quotations shall be disregarded. If fewer than
three quotations are provided, it will be deemed that the Market Quotation in
respect of such Terminated Transaction or group of Terminated Transactions
cannot be determined.

"Non-default Rate" means a rate per annum equal to the cost (without proof or
evidence of any actual cost) to the Non-defaulting Party (as certified by it) if
it were to fund the relevant amount.

"Office" means a branch or office of a party, which may be such party's head or
home office.

"Potential Event of Default" means any event which, with the giving of notice or
the lapse of time or both, would constitute an Event of Default.

"Reference Market-makers" means four leading dealers in the relevant market
selected by the party determining a Market Quotation in good faith (a) from
among dealers of the highest credit standing which satisfy all the criteria that
such party applies generally at the time in deciding whether to offer or to make
an extension of credit and (b) to the extent practicable, from among such
dealers having an office in the same city.

"Relevant Jurisdiction" means, with respect to a party, the jurisdictions (a) in
which the party is incorporated, organised, managed and controlled or considered
to have its seat, (b) where an Office through which the party is acting for
purposes of this Agreement is located, (c) in which the party executes this
Agreement and (d) in relation to any payment, from or through which such payment
is made.

"Scheduled Payment Date" means a date on which a payment or delivery is to be
made under Section 2(a)(i) with respect to a Transaction.

"Set-off" means set-off, offset, combination of accounts, right of retention or
withholding or similar right or requirement to which the payer of an amount
under Section 6 is entitled or subject (whether arising under this Agreement,
another contract, applicable law or otherwise) that is exercised by, or imposed
on, such payer.

"Settlement Amount" means, with respect to a party and any Early Termination
Date, the sum of: --

(a) the Termination Currency Equivalent of the Market Quotations (whether
positive or negative) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation is determined; and

(b) such party's Loss (whether positive or negative and without reference to any
Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not (in
the reasonable belief of the party making the determination) produce a
commercially reasonable result.

"Specified Entity" has the meaning specified in the Schedule.


                                       16

(including an agreement with respect thereto) now existing or hereafter entered
into between one party to this Agreement (or any Credit Support Provider of such
party or any applicable Specified Entity of such party) and the other party to
this Agreement (or any Credit Support Provider of such other party or any
applicable Specified Entity of such other party) which is a rate swap
transaction, basis swap, forward rate transaction, commodity swap, commodity
option, equity or equity index swap, equity or equity index option, bond option,
interest rate option, foreign exchange transaction, cap transaction, floor
transaction, collar transaction, currency swap transaction, cross-currency rate
swap transaction, currency option or any other similar transaction (including
any option with respect to any of these transactions), (b) any combination of
these transactions and (c) any other transaction identified as a Specified
Transaction in this Agreement or the relevant confirmation.

tax.

Termination Date (or, if "Automatic Early Termination" applies, immediately
before that Early Termination Date).

"Termination Currency" has the meaning specified in the Schedule.

"Termination Currency Equivalent" means, in respect of any amount denominated in
the Termination Currency, such Termination Currency amount and, in respect of
any amount denominated in a currency other than the Termination Currency (the
"Other Currency"), the amount in the Termination Currency determined by the
party making the relevant determination as being required to purchase such
amount of such Other Currency as at the relevant Early Termination Date, or, if
the relevant Market Quotation or Loss (as the case may be), is determined as of
a later date, that later date, with the Termination Currency at the rate equal
to the spot exchange rate of the foreign exchange agent (selected as provided
below) for the purchase of such Other Currency with the Termination Currency at
or about 11:00 a.m. (in the city in which such foreign exchange agent is
located) on such date as would be customary for the determination of such a rate
for the purchase of such Other Currency for value on the relevant Early
Termination Date or that later date. The foreign exchange agent will, if only
one party is obliged to make a determination under Section 6(e), be selected in
good faith by that party and otherwise will be agreed by the parties.

"Termination Event" means an Illegality, a Tax Event or a Tax Event Upon Merger
or, if specified to be applicable, a Credit Event Upon Merger or an Additional
Termination Event.

"Termination Rate" means a rate per annum equal to the arithmetic mean of the

2(a)(i) which was (or would have been but for Section 2(a)(iii)) required to be
settled by delivery to such party on or prior to such Early Termination Date and
which has not been so settled as at such Early Termination Date, an amount equal
to the fair market


                                       17
<PAGE>

value of that which was (or would have been) required to be delivered as of the
originally scheduled date for delivery, in each case together with (to the
extent permitted under applicable law) interest, in the currency of such
amounts, from (and including) the date such amounts or obligations were or would
have been required to have been paid or performed to (but excluding) such Early
Termination Date, at the Applicable Rate. Such amounts of interest will be
calculated on the basis of daily compounding and the actual number of days
elapsed. The fair market value of any obligation referred to in clause (b) above
shall be reasonably determined by the party obliged to make the determination
under Section 6(e) or, if each party is so obliged, it shall be the average of
the Termination Currency Equivalents of the fair market values reasonably
determined by both parties.

(j)            Party B represents and warrants:

(3)    ADDITIONAL COVENANT:  In Section 4 add a new paragraph as follows:

       "(f)           CONTRACTING AS PRINCIPAL.  Party A will enter into all
               Transactions as principal and not otherwise and Party B will
               enter into all Transactions in its capacity as trustee of the
               Trust and not otherwise".

(4)    AMENDMENT TO SECTION 6.   In section 6 make the following amendments:

       (i)            Section 6(a) is amended by deleting the words "all
               outstanding Transactions" where they appear and inserting instead
               the words "THE RELEVANT SWAP TRANSACTION".

       (ii)           Add a new section 6(aa):

               "(aa)          RESTRICTED TERMINATION RIGHTS.

               (i)            TERMINATION BY PARTY B:  Party B must not
                      designate an Early Termination Date without the prior
                      written consent of the Note Trustee.

               (ii)           CONSULTATION WITH PARTY A:  Each Party may only
                      designate an Early Termination Date following prior
                      consultation with the other Party as to the timing of the
                      Early Termination Date.  Subject to its duties under the
                      Master Trust Deed and the Series Notice, Party B may
                      exercise any rights in its capacity as holder of the
                      Purchased Receivables only on the instructions of the
                      Note Trustee and only after consultation between Party A
                      and Note Trustee.  Party B may only designate an Early
                      Termination Date at the direction of the Trust Manager.

               (iii)          PARTY A'S LIMITED RIGHTS IN RELATION TO TAX EVENT:
                      Notwithstanding Part 1(b)(iv) of this Schedule, Party A
                      may designate an Early Termination Date if it is an
                      Affected Party following a Tax Event but only if the Note
                      Trustee is satisfied that the Noteholders and
                      Couponholders will be paid in full all principal and
                      interest outstanding on the Notes.

               (iv)           ILLEGALITY:  The parties agree that [unless this
                      Section 6(aa)(iv) is specified not to apply in the
                      Relevant Confirmation,] imposition by any Agency of an
                      Australian jurisdiction of any exchange controls,
                      restrictions or prohibitions will not constitute an
                      Illegality for the purposes of Section 5(b)(i) and Party
                      A will not be entitled to designate an Early Termination
                      Date, and in those circumstances, payment by Party B in
                      accordance with section 2(f) will continue to be proper
                      performance of its payment obligation and Party A's
                      obligations will be unaffected, to the extent of
                      Party_B's payments under section 2(f).

               (v)            TRANSFER WHERE PARTY B DOES NOT GROSS-UP:  If any
                      payment by Party B to Party A under this Agreement is, or
                      is likely to be, made subject to any deduction or
                      withholding on account of Tax, Party B will endeavour to
                      procure the substitution as principal obligor under this
                      Agreement in respect of each affected Transaction of a
                      Party B incorporated in another jurisdiction approved by
                      Party A and the Note Trustee and in respect of which the
                      Designated Rating Agencies confirm that the substitution
                      will not cause a reduction or withdrawal of the rating of
                      the Notes.

<PAGE>

       (iii)          In section 6(b)(ii), add the words "so long as the
               transfer in respect of that Transaction would not lead to a
               rating downgrade of any rated debt of Party B that is secured
               under the Security Trust Deed" after the words "ceases to exist"
               at the end of the first paragraph.

       (iv)           In section 6(e), delete the sentence "The amount, if any,
               payable in respect of an Early Termination Date and determined
               pursuant to this Section will be subject to any Set-off." at the
               end of the first paragraph.

(5)    In section 9, add the following new paragraphs:

       "(h)           FURTHER ASSURANCES.  Each party shall, upon request by
               the other party (the "REQUESTING PARTY") at the expense of the
               requesting party, perform all such acts and execute all such
               agreements, assurances and other documents and instruments as the
               requesting party reasonably requires and which are within the
               powers of that party to assure and confirm the rights and powers
               afforded, created or intended to be afforded or created, under or
               in relation to this Agreement and each Transaction or other
               dealing which occurs under or is contemplated by it.

       (i)            RECORDED CONVERSATION.  Each party:

               (A)            consents to the recording of the telephone
                      conversations of trading and marketing personnel of that
                      party and its Affiliates in connection with this
                      Agreement or any potential Transaction; and

               (B)            agrees to obtain any necessary consent of, and
                      give notice of such recording to, such personnel of it
                      and its Affiliates.

       (j)            ISDA DEFINITIONS:  This Agreement, each Confirmation and
               each Transaction are subject to the 1991 ISDA Definitions (as
               published by the International Swap Dealers Association, Inc.)
               (the "ISDA DEFINITIONS"), and will be governed in all respects by
               any provisions set forth in the ISDA Definitions, without regard
               to any amendments to the ISDA Definitions made after the date of
               this Agreement.  The ISDA Definitions are incorporated by
               reference in, and shall be deemed to be part of, this Agreement
               and each Confirmation.

       (k)            INCONSISTENCY:  In the event of any inconsistency between
               any two or more of the following documents, they shall take
               precedence over each other in the following descending order:

               (i)            any Confirmation;
               (ii)           the Schedule to the Master Agreement;
               (iii)          the other provisions of the Master Agreement; 
               (iv)           the ISDA Definitions."

(6)            FACSIMILE TRANSMISSIONS:  Replace Section 12(a)(iii) with:

       "(iii)         if sent by facsimile, on production of a transmission
               report by the machine from which the facsimile was sent which
               indicates that the facsimile was sent in its entirety to the
               facsimile number of the recipient notified for the purpose of
               this Section unless the recipient notifies the sender within 24
               hours of the facsimile being sent that the facsimile was not
               received in its entirety in legible form;"

(7)            DEFINITIONS:  In section 14:

       (i)            add a new paragraph:

                      "Unless otherwise defined in this Agreement, terms
               defined in the Security Trust Deed (either expressly or by
               incorporation by reference) have the same meaning where used in
               this Agreement."

       (ii)           Insert the following definitions in its appropriate
               alphabetical places in Section 14:

                      "'RELEVANT SWAP TRANSACTION' means, in relation to Class
               A Notes, each Transaction which is a Currency Swap for Class A
               Notes only, and in relation to Class B Notes, each Transaction
               which is a Currency Swap for Class B Notes only."

                      "'SECURITY TRUST DEED' means the Series 1998-1G WST Trust
               Security Trust Deed dated on or about the date of this Agreement
               between Party B as chargor, Perpetual Trustee Company Limited as
               security trustee, the Trust Manager and Party A as note trustee."

<PAGE>

       (iii)          SWAP TRANSACTION.  Any reference to a:

               (a)            "SWAP TRANSACTION" in the 1991 ISDA Definitions is
                      deemed to be a reference to a "Transaction" for the
                      purpose of interpreting this Agreement or any
                      Confirmation; and

               (b)            "TRANSACTION" in this Agreement or any
                      Confirmation is deemed to be a reference to a "Swap
                      Transaction" for the purpose of interpreting the 1991
                      ISDA Definitions.

       (iv)    In the definition of "Market Quotation", on line 1 on page 16 of
               this Agreement, replace the words "been required after that
               date." with:

               "been required after that date and, in respect of each Terminated
               Transaction which is a Relevant Swap Transaction, on the basis
               that the Housing Loan Principal as defined in Series Notice
               referred to in the Terminated Transaction will thereafter have an
               amortisation schedule based on a constant prepayment rate per
               annum ("CPR") equal to:

               (a)    [XX%], if the Replacement Transaction is calculated
                      within one year of the Effective Date of the Terminated
                      Transaction; or

               (b)    if the Replacement Transaction is calculated later than
                      one year after the Effective Date of the Terminated
                      Transaction, the arithmetic mean of four CPRs most
                      recently published prior to the relevant quotation on
                      Bloomberg monitor service in respect of the Class of
                      Notes applicable to the Terminated Transaction (based on
                      data provided to Bloomberg by the Trust Manager)."

(8)            OTHER PROVISIONS, INCLUDING CREDIT SUPPORT:  Insert the following
       Sections 15, 16, 17, 18, 19, 20 and 21 after Section 14:

       "15.           SEGREGATION: 

               The liability of Party B under this Agreement is several and is
               separate in respect of each Relevant Swap Transaction.  The
               failure of Party B to perform its obligations in respect of any
               Relevant Swap Transaction shall not release Party B from its
               obligations under this Agreement or under any other Relevant Swap
               Transaction in respect of any other Notes issued by Party B. 
               Nothing in this Agreement affects the respective priority
               rankings of claims against the Mortgaged Property of Party B
               under the Security Trust Deed.  Without limiting the generality
               of the foregoing, the provisions of this Agreement shall have
               effect separately and severally in respect of each Relevant Swap
               Transaction and shall be enforceable by or against Party B as
               though a separate agreement applied between Party A and Party B
               for each Relevant Swap Transaction, so that (among other things):

               (i)            this Agreement together with each Confirmation
                      relating to a Relevant Swap Transaction will form a
                      single separate agreement between Party A and Party B and
                      references to the respective obligations (including
                      references to payment obligations generally and in the
                      context of provisions for the netting of payments and the
                      calculation of amounts due on early termination) of Party
                      A and Party B shall be construed accordingly as a several
                      reference to each mutual set of obligations arising under
                      each such separate agreement between Party A and Party B;

               (ii)           representations made and agreements entered into
                      by the parties under this Agreement are made and entered
                      separately and severally by Party B in respect of each
                      Relevant Swap Transaction and may be enforced by Party B
                      against Party A separately and severally in respect of
                      each Relevant Swap Transaction;

               (iii)          rights of termination, and obligations and
                      entitlements consequent upon termination, only accrue to
                      Party A against Party_B separately and severally in
                      respect of each Relevant Swap Transaction, and only
                      accrue to Party B against Party A separately and
                      severally in respect of each Relevant Swap Transaction;
                      and

               (iv)           the occurrence of an Event of Default or
                      Termination Event in respect of a Relevant Swap
                      Transaction does not in itself constitute an Event of
                      Default or Termination Event in respect of any other
                      Relevant Swap Transaction."

<PAGE>

       16.            RECOURSE

               Party B enters into this Agreement in its capacity as Trustee of
               the Trust, and Clause 3.3(b) of the Series Notice applies to this
               Agreement as if set out in full.  Clause 16 of the Security Trust
               Deed shall apply to govern Party A's priority to moneys received
               from the sale of Assets or other enforcement of the Charge under
               the Security Trust Deed.

               This Section 16:

               (i)            applies even though any other provision of this
                      Agreement is not made subject to it; and

               (ii)           overrides any other provision of this Agreement
                      which is inconsistent with it.

17.            THE MANAGER

       Party A acknowledges that the Manager will, at the request of Party B,
       perform the day to day management of the Trust on the terms and
       conditions of the Master Trust Deed and Series Notice.  Unless expressly
       advised to the contrary in writing by Party B from time to time, any
       rights or obligations of Party B under this Agreement may be exercised
       or satisfied (as the case may be) by the Manager on behalf of Party B
       and Party A is not obliged to enquire as to the authority of the Manager
       to take such action on behalf of Party B.  Except where the context
       otherwise requires, references in this Agreement to a "party" to this
       Agreement are to Party A or Party B.

18.            TRUST DEED

       The parties acknowledge and agree that, for the purposes of the Master
       Trust Deed and the Trust Documents, this Agreement is a "Hedge
       Agreement" and Party A is a "Swap Provider" and "Support Facility
       Provider"."

19.            REPLACEMENT CURRENCY SWAP

       (a)            If this Agreement is terminated, Party B may, at the
               direction of the Trust Manager, enter into one or more currency
               swaps which replace the Transactions under this Agreement
               (collectively a "Replacement Currency Swap") but only on the
               condition that the Settlement Amount payable (if any) by Party B
               to Party A upon termination of this Agreement will be paid in
               full when due in accordance with the Series Notice and this
               Agreement.

       (b)            If the condition in section 19(a) is satisfied, Party B
               may enter into the Replacement Currency Swap and if it does so it
               must direct the Replacement Currency Swap to pay any upfront
               premium to enter into the Replacement Currency Swap due to Party
               B directly to Party A in satisfaction of and to the extent of
               Party B's obligation to pay the Settlement Amount to Party A as
               referred to in section 19(a), and to the extent that such premium
               is not greater than or equal to the Settlement Amount, the
               balance may be satisfied by Party B as a Trust Expense (as
               defined in the Series Notice).

       (c)            The obligations of Party B (and the rights of Party A)
               under this section 19 constitute separate and independent
               obligations of Party B (and rights of Party A) and shall survive
               the termination of this Agreement.

20.            CREDIT SUPPORT

       (a)            In consideration of Party B entering into an agreement on
               the same material terms as this Agreement with the Credit Support
               Provider (the "Other Agreement") and Transactions under the other
               Agreement on the same material terms as Transactions under this
               Agreement, the Credit Support Provider hereby unconditionally
               guarantees to Party B the payment by Party A of moneys which are
               payable by Party A under a Relevant Swap Transaction (on terms
               set out in this Agreement and in the Confirmation for that
               Relevant Swap Transaction) (the "Payable Moneys") to Party B in
               the event that Party A defaults in the payment of those Payable
               Moneys.  

<PAGE>

       (b)            If Party B has not been, or Party A reasonably expects
               that Party B is not going to be, paid all or any part of the
               presently payable Payable Moneys by Party A, then Party A or
               Party B may by notice to the Credit Support Provider demand
               payment of the Payable Moneys in respect of which demand is being
               made.  The Credit Support Provider's obligations to pay the
               presently payable Payable Moneys which have not been paid by
               Party A shall not, however, be conditional upon the Credit
               Support Provider receiving such notice of demand.

       (c)            The Credit Support Provider agrees that it will not,
               unless and until all the present and prospective Payable Moneys
               have been paid, exercise any rights of subrogation which it may
               acquire due to its payment of Payable Moneys under section 20(a).

       (d)            All payments by the Credit Support Provider shall be made
               in the currency in which the Payable Moneys are denominated.

       (e)            Party B agrees that, without affecting its rights under
               clause 21, to the extent that the Credit Support Provider pays
               the Payable Moneys and thereby avoids or remedies a default by
               Party A, Party B shall not be entitled to designate an Early
               Termination Date in respect of that default by Party A, and such
               a payment by the Credit Support Provider shall be deemed to be an
               "actual payment" as referred to in line 6 of section 2(e) of this
               Agreement.

       (f)            The provisions of this section 20 shall constitute
               irrevocable obligations of the Credit Support Provider until a
               notice of revocation is served by the Credit Support Provider on
               Party B, but such a notice cannot and shall not be served without
               the prior written consent of Party A, the Note Trustee and the
               Trust Manager in consultation with the Designated Rating
               Agencies.

21.    CREDIT SUPPORT PROVIDER TRANSACTIONS

       (a)            The Credit Support Provider may give a Substitution
               Notice to Party B specifying a Transaction which shall be
               substituted under this Section 21 (a "Replaced Transaction"), but
               only on the condition that a Credit Event has occurred in respect
               of Party A.  

       (b)            If the Credit Support Provider gives a Substitution
               Notice under paragraph 21(a), then either:

               (i)            a Substitute Transaction shall become effective
                      and the Effective Date shall be the date specified in the
                      Substitution Notice; or

               (ii)   both:

                      (A)          Party B, the Credit Support Provider and the
                              Trust Manager must enter into an Equivalent
                              Transaction with a suitably rated counterparty
                              procured by the Credit Support Provider and
                              accepted by Party B, the Trust Manager and the
                              Note Trustee (the "New Currency Swap Provider")
                              and the Effective Date shall be the date specified
                              in the Substitution Notice as the Effective Date
                              for the Equivalent-Other Transaction; and 

                      (B)          an Equivalent-Other Transaction shall become
                              effective and the Effective Date shall be the date
                              specified in the Substitution Notice.  The New
                              Currency Swap Provider must sign, and Party B, the
                              Credit Support Provider and the Trust Manager must
                              countersign, an accession as provided for in the
                              Confirmation for the Equivalent-Other Transaction.

                      For the avoidance of doubt, a Substitution Notice may
               specify that a Substitution Transaction will become effective in
               accordance with paragraph (b)(i) or that an Equivalent
               Transaction and an Equivalent Other Transaction will become
               effective in accordance with paragraphs (b)(ii)(A) and (B), or
               that either a Transaction under paragraph (b)(i) or Transactions
               under paragraphs (b)(ii)(A) and (B) shall become effective as
               alternatives.  If the Substitution Notice specifies that, as
               alternatives, the Transaction or Transactions under paragraphs
               (b)(i) or (b)(ii)(A) and (B) shall become effective, and if a
               suitably rated counterparty is not procured by the Credit Support
               Provider under paragraph (b)(ii)(A), the Substitute Transaction
               must become effective in accordance with paragraph (b)(i).

       (c)            On the date on which the Transactions become effective in
               accordance with a Substitution Notice under either paragraph
               (b)(i) or (b)(ii):

               (i)    the Replaced Transaction shall terminate; and 

               (ii)   the Other Transaction shall terminate.

       (d)     No Settlement Amount or other amount under section 6 or section
               11 shall be payable by, or to, Party B (as the case may be) upon
               the termination of the Transactions under paragraphs (c)(i) and
               (ii), because the Transactions specified in paragraphs (b)(i), or
               (b)(ii)(A) and (B), as the case may be, shall have the effect of
               preserving for Party B the economic equivalent of the payments
               under the Transactions which are being terminated.

                              Obligation is below the Initial Price of such by

                      in an aggregate amount  of not less than the applicable
                      Threshold Amount which has resulted in the Specified
                      Indebtedness becoming due and payable under such
                      agreements or instruments before it would otherwise have
                      been due and payable, or (B) a default by Party A in
                      making one or more payments on the due date thereof in an

                      Threshold Amount under such agreements or instruments
                      (after giving effect to any applicable notice requirement
                      or grace period).   

                      For the purposes of this paragraph (e)(ii), "Specified
                      Indebtedness" and "Threshold Amount" shall have the
                      meanings given in the Confirmation for the relevant
                      Transaction; or

               (iii)  the occurrence with respect to Party A of an event

13.            ELECTIONS AND VARIABLES

       (a)            SECURITY INTEREST FOR "OBLIGATIONS"

               The term "Obligations" as used in this Annex does not include any
               additional obligations.  For the avoidance of doubt, in respect
               of the Obligations which are specified in the Relevant Swap
               Transactions, any assumptions made for the purposes of
               calculating the Peak Exposure in Paragraph 13(b)(i) or the
               Benefit Exposure in Paragraph 13(b)(iv)(A) must not be applied or
               otherwise taken into account for the purpose of calculating the
               Obligations, since those assumptions are theoretical only and do
               not accurately reflect any actual Obligations.

       (b)            CREDIT SUPPORT OBLIGATIONS

               (i)            DELIVERY AMOUNT, RETURN AMOUNT AND CREDIT SUPPORT
                      AMOUNT

                      "DELIVERY AMOUNT" and "RETURN AMOUNT" each has the
                      meaning specified in Paragraph 3.

                      "CREDIT SUPPORT AMOUNT" means, for any Valuation Date:

                      (A)     (I)  with respect to Party A as the Secured
                                   Party, Party_A's Exposure for that
                                   Valuation Date; or

                              (II) with respect to Party B as the Secured
                                   Party, Party B's Peak Exposure for that
                                   Valuation Date; plus

                      (B)          the aggregate of all Independent Amounts
                              applicable to the Pledgor, if any; minus

                      (C)          all Independent Amounts applicable to the
                              Secured Party, if any; minus

                      (D)          the Pledgor's Threshold,

                      provided, however, that the Credit Support Amount will be
                      deemed to be zero whenever the calculation of Credit
                      Support Amount yields a number less than zero.

                      "PEAK EXPOSURE" means the amount equal to Party B's
                      maximum credit exposure in respect of a Replacement
                      Transaction entered into on a date three months after the
                      Valuation Date, calculated by the Valuation Agent using
                      its swap credit exposure methodology to a 99% confidence
                      interval, as that methodology is updated to reflect,
                      without limitation, the levels of volatility current as
                      at the Valuation Time for the differential between
                      USD-LIBOR-BBA and AUD-BBR-BBSW (each rate with a
                      Designated Maturity of three months) and the A$-US$
                      forward exchange rates, and assuming that from that
                      Valuation Date:

                          CREDIT SUPPORT PROVIDER PROVISIONS

Each Transaction under this Confirmation shall be capable of being specified as
a Replaced Transaction in accordance with the provisions of Section 21 of the
Agreement.  Those provisions shall apply as further specified below.

1.     Definitions for Credit Events

       "CALCULATION AGENT" means the party to the Transaction (or a third
       party) designated as such for the Transaction.  The Calculation Agent's
       calculations and determinations shall be made in good faith, in a
       commercially reasonable manner and be binding in the absence of manifest
       error [Credit Support Provider];

       "INITIAL PRICE" means, with respect to any Reference Obligation, the
       percentage listed with respect thereto in the definition of Reference
       Obligation herein as the Initial Price;

<PAGE>

       "INTEREST RATE ADJUSTMENT AMOUNT" means, with respect to any Reference
       Obligation, the absolute value of the difference between (i) the Mark to
       Market Value and (ii) 100% minus the Initial Price;

       "MARK TO MARKET VALUE" means, in the determination of the Calculation
       Agent, with respect to any Reference Obligation, on any day, the mark to
       market value payable on that day (expressed as a percentage of the
       notional amount thereof), of a hypothetical interest rate swap
       commencing on the Effective Date between a hypothetical party ("Party
       X") and a counterparty with the highest long term senior debt rating of
       each Rating Agency, which swap has a notional amount equal to the
       Floating Rate Payer Calculation Amount and under which Party X (i) pays
       the Mark to Market Rate plus the Initial Spread and (ii) receives a
       fixed interest amount equal in amount and timing to the coupons on the
       Reference Obligation.  If, under such swap, Party X would be due to pay
       such mark to market value, Mark to Market Value will be negative and, if
       Party X would be due to receive such mark to market value, the Mark to
       Market Value will be positive.

       "MARKET VALUE" means, in accordance with the Quotation Method, the
       percentage equal to the arithmetic mean of quotations (exclusive of
       accrued but unpaid interest and expressed as a percentage) obtained from
       Dealers with respect to a Valuation Date in the manner provided below. 
       In obtaining such price quotations from Dealers, the Calculation Agent
       will request each Dealer to provide firm bid and offer quotations for an
       aggregate amount of the Reference Obligation equal to the Quotation
       Amount to the extent reasonably practicable as of the Valuation Time on
       such Valuation Date.  If more than three quotations are provided on such
       date, the Market Value shall be the arithmetic mean of such quotations
       without regard to the quotations having the highest and lowest values. 
       If exactly three quotations are provided, the Market Value shall be the
       quotation remaining after disregarding the highest and lowest
       quotations.  For this purpose, if more than one quotation has the same
       highest value or lowest value, then one of such quotations shall be
       disregarded.  If exactly two quotations are provided, the Market Value
       shall be the arithmetic mean of such quotations.  If fewer than two
       quotations are provided, then the Market Value shall be an amount as
       determined by the Calculation Agent on the next Business Day on which at
       least two quotations are provided by Dealers.  If the Calculation Agent
       is unable to calculate the Market Value prior to the fifth Business Day
       following the applicable Valuation Date, then the Calculation Agent
       shall determine the Market Value for such Valuation Date in its
       reasonable discretion;

       "QUOTATION METHOD":

               [Mid-market means that only the arithmetic mean of the bid and
               offer quotations provided by Dealers that have provided both bid
               and offer quotations shall be used in the calculation of Market
               Value.];

       "REFERENCE OBLIGATION" means the obligation(s) as follows: 

       Issuer/Borrower:            [                     ]
       Guarantor:                  [                     ]
       Maturity:                   [                     ]
       Coupon:                     [                     ]
       CUSIP/ISIN:                 [                     ]

       Initial Spread:             [                     ];

       "SPECIFIED INDEBTEDNESS" means any obligation (whether present or
       future, contingent or otherwise, as principal or surety or otherwise in
       respect of money borrowed or raised or under any finance lease,
       redeemable preference share, letter of credit, futures contract,
       guarantee, indemnity or a transaction of a type described in the last 6
       lines of the definition of Specified Transaction.

       "VALUATION TIME" - [                             ]

2.     The parties acknowledge that on the Effective Date of the Substitute
       Transaction or the Equivalent Transaction, Party A shall pay to the
       Credit Support Provider (in the case of the Substitute Transaction) or
       to the new Currency Swap Provider (in the case of the Equivalent
       Transaction) the amount equal to the amount (if a positive number) that
       hypothetically would have been payable by Party A to Party B under
       Section 6(e)(i)(3) if:

       (a)     the Transaction had been terminated;

       (b)     an Early Termination Date had occurred on the Effective Date; and

       (c)     Section 21 had not applied in respect of the Transaction.

       Any such amount shall be payable by Party A to the Credit Support
       Provider in accordance with the provisions of the relevant Master
       Agreement between Party A and the Credit Support Provider (in the case
       of the Substitute Transaction) or to the New Currency Swap Provider in
       accordance with the relevant Master Agreement between Party A and the
       New Currency Swap Provider (in the case of the Equivalent Transaction).

Value and (ii) 100% minus the Initial Price;

"MARK TO MARKET VALUE" means, in the determination of the Calculation Agent,
with respect to any Reference Obligation, on any day, the mark to market value
payable on that day (expressed as a percentage of the notional amount thereof),
of a hypothetical interest rate swap commencing on the Effective Date between a
hypothetical party ("Party X") and a counterparty with the highest long term
senior debt rating of each Rating Agency, which swap has a notional amount equal
to the Floating Rate Payer Calculation Amount and under which Party X (i) pays
the Mark to Market Rate plus the Initial Spread and (ii) receives a fixed
interest amount equal in amount and timing to the coupons on the Reference
Obligation.  If, under such swap, Party X would be due to pay such mark to
market value, Mark to Market Value will be negative and, if Party X would be due
to receive such mark to market value, the Mark to Market Value will be positive.

"MARKET VALUE" means, in accordance with the Quotation Method, the percentage
equal to the arithmetic mean of quotations (exclusive of accrued but unpaid
interest and expressed as a percentage) obtained from Dealers with respect to a
Valuation Date in the manner provided below.  In obtaining such price quotations
from Dealers, the Calculation Agent will request each Dealer to provide firm bid
and offer quotations for an aggregate amount of the Reference Obligation equal
to the Quotation Amount to the extent reasonably practicable as of the Valuation
Time on such Valuation Date.  If more than three quotations are provided on such
date, the Market Value shall be the arithmetic mean of such quotations without
regard to the quotations having the highest and lowest values.  If exactly three
quotations are provided, the Market Value shall be the quotation remaining after
disregarding the highest and lowest quotations.  For this purpose, if more than
one quotation has the same highest value or lowest value, then one of such
quotations shall be disregarded.  If exactly two quotations are provided, the
Market Value shall be the arithmetic mean of such quotations.  If fewer than two
quotations are provided, then the Market Value shall be an amount as determined
by the Calculation Agent on the next Business Day on which at least two
quotations are provided by Dealers.  If the Calculation Agent is unable to
calculate the Market Value prior to the fifth Business Day following the
applicable Valuation Date, then the Calculation Agent shall determine the Market
Value for such Valuation Date in its reasonable discretion;

"QUOTATION METHOD":

       [Bid means that only the bid quotations provided by Dealers shall be
       used in the calculation of Market Value] or

       [Offer means that only the offer quotations provided by Dealers shall be
       used in the calculation of Market Value.] or

       [Mid-market means that only the arithmetic mean of the bid and offer
       quotations provided by Dealers that have provided both bid and offer
       quotations shall be used in the calculation of Market Value.];

CREDIT SUPPORT PROVIDER PROVISIONS

Each Transaction under this Confirmation shall be capable of being specified as
a Replaced Transaction in accordance with the provisions of Section 21 of the
Agreement.  Those provisions shall apply as further specified below.

1.   Definitions for Credit Events

     "CALCULATION AGENT" means the party to the Transaction (or a third party)
     designated as such for the Transaction.  The Calculation Agent's
     calculations and determinations shall be made in good faith, in a
     commercially reasonable manner and be binding in the absence of manifest
     error [Credit Support Provider];

     "INITIAL PRICE" means, with respect to any Reference Obligation, the
     percentage listed with respect thereto in the definition of Reference
     Obligation herein as the Initial Price;

<PAGE>

     "INTEREST RATE ADJUSTMENT AMOUNT" means, with respect to any Reference
     Obligation, the absolute value of the difference between (i) the Mark to
     Market Value and (ii) 100% minus the Initial Price;

     "MARK TO MARKET VALUE" means, in the determination of the Calculation
     Agent, with respect to any Reference Obligation, on any day, the mark to
     market value payable on that day (expressed as a percentage of the notional
     amount thereof), of a hypothetical interest rate swap commencing on the
     Effective Date between a hypothetical party ("Party X") and a counterparty
     with the highest long term senior debt rating of each Rating Agency, which
     swap has a notional amount equal to the Floating Rate Payer Calculation
     Amount and under which Party X (i) pays the Mark to Market Rate plus the
     Initial Spread and (ii) receives a fixed interest amount equal in amount
     and timing to the coupons on the Reference Obligation.  If, under such
     swap, Party X would be due to pay such mark to market value, Mark to Market
     Value will be negative and, if Party X would be due to receive such mark to
     market value, the Mark to Market Value will be positive.

     "MARKET VALUE" means, in accordance with the Quotation Method, the
     percentage equal to the arithmetic mean of quotations (exclusive of accrued
     but unpaid interest and expressed as a percentage) obtained from Dealers
     with respect to a Valuation Date in the manner provided below.  In
     obtaining such price quotations from Dealers, the Calculation Agent will
     request each Dealer to provide firm bid and offer quotations for an
     aggregate amount of the Reference Obligation equal to the Quotation Amount
     to the extent reasonably practicable as of the Valuation Time on such
     Valuation Date.  If more than three quotations are provided on such date,
     the Market Value shall be the arithmetic mean of such quotations without
     regard to the quotations having the highest and lowest values.  If exactly
     three quotations are provided, the Market Value shall be the quotation
     remaining after disregarding the highest and lowest quotations.  For this
     purpose, if more than one quotation has the same highest value or lowest
     value, then one of such quotations shall be disregarded.  If exactly two
     quotations are provided, the Market Value shall be the arithmetic mean of
     such quotations.  If fewer than two quotations are provided, then the
     Market Value shall be an amount as determined by the Calculation Agent on
     the next Business Day on which at least two quotations are provided by
     Dealers.  If the Calculation Agent is unable to calculate the Market Value
     prior to the fifth Business Day following the applicable Valuation Date,
     then the Calculation Agent shall determine the Market Value for such
     Valuation Date in its reasonable discretion;

     "QUOTATION METHOD":

          [Mid-market means that only the arithmetic mean of the bid and offer
          quotations provided by Dealers that have provided both bid and offer 
          quotations shall be used in the calculation of Market Value.];

Each Transaction under this Confirmation shall be capable of being specified as
a Replaced Transaction in accordance with the provisions of Section 21 of the
Agreement.  Those provisions shall apply as further specified below.

<PAGE>

1.   Definitions for Credit Events

     "CALCULATION AGENT" means the party to the Transaction (or a third party)
     designated as such for the Transaction.  The Calculation Agent's
     calculations and determinations shall be made in good faith, in a
     commercially reasonable manner and be binding in the absence of manifest
     error [Credit Support Provider];

     "INITIAL PRICE" means, with respect to any Reference Obligation, the
     percentage listed with respect thereto in the definition of Reference
     Obligation herein as the Initial Price;

     "INTEREST RATE ADJUSTMENT AMOUNT" means, with respect to any Reference
     Obligation, the absolute value of the difference between (i) the Mark to
     Market Value and (ii) 100% minus the Initial Price;

     "MARK TO MARKET VALUE" means, in the determination of the Calculation
     Agent, with respect to any Reference Obligation, on any day, the mark to
     market value payable on that day (expressed as a percentage of the notional
     amount thereof), of a hypothetical interest rate swap commencing on the
     Effective Date between a hypothetical party ("Party X") and a counterparty
     with the highest long term senior debt rating of each Rating Agency, which
     swap has a notional amount equal to the Floating Rate Payer Calculation
     Amount and under which Party X (i) pays the Mark to Market Rate plus the
     Initial Spread and (ii) receives a fixed interest amount equal in amount
     and timing to the coupons on the Reference Obligation.  If, under such
     swap, Party X would be due to pay such mark to market value, Mark to Market
     Value will be negative and, if Party X would be due to receive such mark to
     market value, the Mark to Market Value will be positive.

     "MARKET VALUE" means, in accordance with the Quotation Method, the
     percentage equal to the arithmetic mean of quotations (exclusive of accrued
     but unpaid interest and expressed as a percentage) obtained from Dealers
     with respect to a Valuation Date in the manner provided below.  In
     obtaining such price quotations from Dealers, the Calculation Agent will
     request each Dealer to provide firm bid and offer quotations for an
     aggregate amount of the Reference Obligation equal to the Quotation Amount
     to the extent reasonably practicable as of the Valuation Time on such
     Valuation Date.  If more than three quotations are provided on such date,
     the Market Value shall be the arithmetic mean of such quotations without
     regard to the quotations having the highest and lowest values.  If exactly
     three quotations are provided, the Market Value shall be the quotation
     remaining after disregarding the highest and lowest quotations.  For this
     purpose, if more than one quotation has the same highest value or lowest
     value, then one of such quotations shall be disregarded.  If exactly two
     quotations are provided, the Market Value shall be the arithmetic mean of
     such quotations.  If fewer than two quotations are provided, then the
     Market Value shall be an amount as determined by the Calculation Agent on
     the next Business Day on which at least two quotations are provided by
     Dealers.  If the Calculation Agent is unable to calculate the Market Value
     prior to the fifth Business Day following the applicable Valuation Date,
     then the Calculation Agent shall determine the Market Value for such
     Valuation Date in its reasonable discretion;

     "QUOTATION METHOD":

          [Bid means that only the bid quotations provided by Dealers shall be
          used in the calculation of Market Value] or

          [Offer means that only the offer quotations provided by Dealers shall
          be used in the calculation of Market Value.] or

          [Mid-market means that only the arithmetic mean of the bid and offer
          quotations provided by Dealers that have provided both bid and offer
          quotations shall be used in the calculation of Market Value.];

     "REFERENCE OBLIGATION" means the obligation(s) as follows:

     Issuer/Borrower:                   [                     ]
     Guarantor:                         [                     ]
     Maturity:                          [                     ]
     Coupon:                            [                     ]
     CUSIP/ISIN:                        [                     ]

     Initial Spread:                    [                     ];

     contingent or otherwise, as principal or surety or otherwise in respect of

     Transaction or the Equivalent Transaction, Party A shall pay to the Credit
     Support Provider (in the case of the Substitute Transaction) or to the new
     Currency Swap Provider (in the case of the Equivalent Transaction) the
     amount equal to the amount (if a positive number) that hypothetically would
     have been payable by Party A to Party B under Section 6(e)(i)(3) if:

     (a)  the Transaction had been terminated;

     (b)  an Early Termination Date had occurred on the Effective Date; and

     (c)  Section 21 had not applied in respect of the Transaction.


     Any such amount shall be payable by Party A to the Credit Support Provider
     in accordance with the provisions of the relevant Master Agreement between
     Party A and the Credit Support Provider (in the case of the Substitute
     Transaction) or to the New Currency Swap Provider in accordance with the
     relevant Master Agreement between Party A and the New Currency Swap
     Provider (in the case of the Equivalent Transaction).

such change applies unless such other party gives timely notice of a reasonable
objection to such change.

(c) Netting. If on any date amounts would otherwise be payable: --

      (i) in the same currency; and

      (ii) in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to make
payment or any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount
will be determined in respect of all amounts payable on the same date in the
same currency in respect of such Transactions, regardless of whether such
amounts are payable in respect of the same Transaction. The election may be made
in the Schedule or a Confirmation by specifying that subparagraph (ii) above
will not apply to the Transactions identified as being subject to the election,
together with the starting date (in which case subparagraph (ii) above will not,
or will cease to, apply to such Transactions from such date). This election may
be made separately for different groups of Transactions and will apply
separately to each pairing of Offices through which the parties make and receive
payments or deliveries.

(d) Deduction or Withholding for Tax.

      (i) Gross-Up. All payments under this Agreement will be made without any
      deduction or withholding for or on account of any Tax unless such
      deduction or withholding is required by any applicable law, as modified by
      the practice of any relevant governmental revenue authority, then in
      effect. If a party is so required to deduct or withhold, then that party
      ("X") will: --

            (1) promptly notify the other party ("Y") of such requirement;

            (2) pay to the relevant authorities the full amount required to be
            deducted or withheld (including the full amount required to be
            deducted or withheld from any additional amount paid by X to Y under
            this Section 2(d)) promptly upon the earlier of determining that
            such deduction or withholding is required or receiving notice that
            such amount has been assessed against Y;

            (3) promptly forward to Y an official receipt (or a certified copy),
            or other documentation reasonably acceptable to Y, evidencing such
            payment to such authorities; and

            (4) if such Tax is an Identifiable Tax, pay to Y, in addition to the
            payment to which Y is otherwise entitled under this Agreement, such
            additional amount as is necessary to ensure that the net amount
            actually received by Y (free and clear of Indemnifiable Taxes,
            whether assessed against X or Y) will equal the full amount Y would
            have received had no such deduction or withholding been required.
            However, X will not be required to pay any additional amount to Y to
            the extent that it would not be required to be paid but for: --

                  (A) the failure by Y to comply with or perform any agreement
                  contained in Section 4(a)(i), 4(a)(iii) or 4(d); or

                  (B) the failure of a representation made by Y pursuant to
                  Section 3(f) to be accurate and true unless such failure would
                  not have occurred but for (I) any action taken by a taxing
                  authority, or brought in a court of competent jurisdiction, on
                  or after the date on which a Transaction is entered into
                  (regardless of whether such action is taken or brought with
                  respect to a party to this Agreement) or (II) a Change in Tax
                  Law.


                                       2
<PAGE>

      (ii) Liability. if: --

            (1) X is required by any applicable law, as modified by the practice
            of any relevant governmental revenue authority, to make any
            deduction or withholding in respect of which X would not be required
            to pay an additional amount to Y under Section 2(d)(i)(4);

            (2) X does not so deduct or withhold; and
 
            (3) a liability resulting from such Tax is assessed directly against
            X,

      then, except to the extent Y has satisfied or then satisfies the liability
      resulting from such Tax, Y will promptly pay to X the amount of such
      liability (including any related liability for interest, but including any
      related liability for penalties only if Y has failed to comply with or
      perform any agreement contained in Section 4(a)(i), 4(a)(iii) or 4(d)).

(e) Default Interest; Other Amounts. Prior to the occurrence or effective
designation of an Early Termination Date in respect of the relevant Transaction,
a party that defaults in the performance of any payment obligation will, to the
extent permitted by law and subject to Section 6(c), be required to pay interest
(before as well as after judgement) on the overdue amount to the other party on
demand in the same currency as such overdue amount, for the period from (and
including) the original due date for payment to (but excluding) the date of
actual payment, at the Default Rate. Such interest will be calculated on the
basis of daily compounding and the actual number of days elapsed. If, prior to
the occurrence or effective designation of an Early Termination Date in respect
of the relevant Transaction, a party defaults in the performance of any
obligation required to be settled by delivery, it will compensate the other
party on demand if and to the extent provided for in the relevant Confirmation
or elsewhere in this Agreement.

3. Representations

Each party represents to the other party (which representations will be deemed
to be repeated by each party on each date on which a Transaction is entered into
and, in the case of the representations in Section 3(f), at all times until the
termination of this Agreement) that: --

(a) Basic Representations.

      (i) Status. It is duly organised and validly existing under the laws of
      the jurisdiction of its organsiation or incorporation and, if relevant
      under such laws, in good standing;

      documentation relating to this Agreement to which it is a party, to

      its obligations under this Agreement and any obligations it has under any
      Credit Support Document to which it is a party and has taken all necessary
      action to authorise such execution, delivery and performance;

      (iii) No Violation or Conflict. Such execution, delivery and performance
      do not violate or conflict with any law applicable to it, any provision of

      contractual restriction binding on or affecting it or any of its assets;

      (iv) Consents. All governmental and other consents that are required to
      have been obtained by it with respect to this Agreement or any Credit

      force and effect and all conditions of any such consents have been
      complied with; and

      (v) Obligations Binding. Its obligations under this Agreement and any
      Credit Support Document to which it is a party constitute its legal, valid
      and binding obligations, enforceable in accordance with their respective
      terms (subject to applicable bankruptcy, reorganisation, insolvency,
      moratorium or similar laws affecting creditors' rights generally and
      subject, as to enforceability, to equitable principles of general
      application (regardless of whether enforcement is sought in a proceeding
      in equity or at law)).


                                       3
<PAGE>

(b) Absence of Certain Events. No Event of Default or Potential Event of Default

entering into or performing its obligations under this Agreement or any Credit
Support Document to which it is a party.

(c) Absence of Litigation. There is not pending, to its knowledge, threatened
against it or any of its Affiliates any action, suit or proceeding at law or in

against it of this Agreement or any Credit Support Document to which it is a
party or its ability to perform its obligations under this Agreement or such
Credit Support Document.

(d) Accuracy of Specified Information. All applicable information that is

which it is a party: --

(a) Furnish Specified Information. It will deliver to the other party or, in
certain cases under subparagraph (iii) below, to such government or taxing
authority as the other party reasonably directs: --

      (i) any forms, documents or certificates relating to taxation specified in
      the Schedule or any Confirmation;

      (ii) any other documents specified in the Schedule or any Confirmation;
      and

      (iii) upon reasonable demand by such other party, any form or document
      that may be required or reasonably requested in writing in order to allow
      such other party or its Credit Support Provider to make a payment under
      this Agreement or any applicable Credit Support Document without any
      deduction or withholding for or on account of any Tax or with such
      deduction or withholding at a reduced rate (so long as the completion,
      execution or submission of such form or document would not materially
      prejudice the legal or commercial position of the party in receipt of such
      demand), with any such form or document to be accurate and completed in a
      manner reasonably satisfactory to such other party and to be executed and
      to be delivered with any reasonably required certification,

in each case by the date specified in the Schedule or such Confirmation or, if
none is specified, as soon as reasonably practicable.

(b) Maintain Authorisations. It will use all reasonable efforts to maintain in
full force and effect all consents of any governmental or other authority that
are required to be obtained by it with respect to this Agreement or any Credit
Support Document to which it is a party and will use all reasonable efforts to
obtain any that may become necessary in the future.

applicable laws and orders to which it may be subject if failure so to comply
would materially impair its ability to perform its obligations under this

by it under Section 3(f) to be accurate and true promptly upon learning of such
failure.

<PAGE>

organised, managed and controlled, or considered to have its seat, or in which a
branch or office through which it is acting for the purpose of this Agreement is
located ("Stamp Tax Jurisdiction") and will indemnify the other party against
any Stamp Tax levied or imposed upon the other part or in respect of the other
party's execution or performance of this Agreement by any such Stamp Tax
Jurisdiction which is not also a Stamp Tax Jurisdiction with respect to the
other party.

5. Events of Default and Termination Events

(a) Events of Default. The occurrence at any time with respect to a party or, if
applicable, any Credit Support Provider of such party or any Specified Entity of
such party of any of the following events constitutes an event of default (an
"Event of Default") with respect to such party: --

      (i) Failure to Pay or Deliver. Failure by the party to make, when due, any
      payment under this Agreement or delivery under Section 2(a)(i) or 2(e)
      required to be made by it if such failure is not remedied on or before the
      third Local Business Day after notice of such failure is given to the
      party;

      (ii) Breach of Agreement. Failure by the party to comply with or perform
      any agreement or obligation (other than an obligation to make any payment
      under this Agreement or delivery under Section 2(a)(i) or 2(e) or to give
      notice of a Termination Event or any agreement or obligation under Section
      4(a)(i), 4(a)(iii) or 4(d)) to be complied with or performed by the party
      in accordance with this Agreement if such failure is not remedied on or
      before the thirtieth day after notice of such failure is given to the
      party;

      (iii) Credit Support Default.

            (1) Failure by the party or any Credit Support Provider of such
            party to comply with or perform any agreement or obligation to be
            complied with or performed by it in accordance with any Credit
            Support Document if such failure is continuing after any applicable
            grace period has elapsed;

            (2) the expiration or termination of such Credit Support Document or
            the failing or ceasing of such Credit Support Document to be in full
            force and effect for the purpose of this Agreement (in either case
            other than in accordance with its terms) prior to the satisfaction
            of all obligations of such party under each Transaction to which
            such Credit Support Document relates without the written consent of
            the other party; or

            (3) the party or such Credit Support Provider disaffirms, disclaims,
            repudiates or rejects, in whole or in part, or challenges the
            validity of, such Credit Support Document;

      (iv) Misrepresentation. A representation (other than a representation
      under Section 3(e) or (f)) made or repeated or deemed to have been made or
      repeated by the party or any Credit Support Provider of such party in this
      Agreement or any Credit Support Document proves to have been incorrect or
      misleading in any material respect when made or repeated or deemed to have
      been made or repeated;

      (v) Default under Specified Transaction. The party, any Credit Support
      Provider of such party or any applicable Specified Entity of such party
      (1) defaults under a Specified Transaction and, after giving effect to any
      applicable notice requirement or grace period, there occurs a liquidation
      of, an acceleration of obligations under, or an early termination of, that
      Specified Transaction, (2) defaults, after giving effect to any applicable
      notice requirement or grace period, in making any payment or delivery due
      on the last payment delivery or exchange date of, or any payment on early
      termination of, a Specified Transaction (or such default continues for at
      least three Local Business Days if there is no applicable notice
      requirement or grace period) or (3) disaffirms, disclaims, repudiates or
      rejects, in whole or in part, a Specified Transaction (or such action is
      taken by any person or entity appointed or empowered to operate it or act
      on its behalf);

      (vi) Cross Default. If "Cross Default" is specified in the Schedule as
      applying to the party, the occurrence or existence of (1) a default, event
      of default or other similar condition or event (however


                                       5
<PAGE>

      described) in respect of such party, any Credit Support Provider of such
      party or any applicable Specified Entity of such party under one or more
      agreements or instruments relating to Specified Indebtedness of any of
      them (individually or collectively) in an aggregate amount of not less
      than the applicable Threshold Amount (as specified in the Schedule) which
      has resulted in such Specified Indebtedness becoming, or becoming capable
      at such time of being declared, due and payable under such agreements or
      instruments, before it would otherwise have been due and payable or (2) a
      default by such party, such Credit Support Provider or such Specified
      Entity (individually or collectively) in making one or more payments on
      the due date thereof in an aggregate amount of not less than the
      applicable Threshold Amount under such agreements or instruments (after
      giving effect to any applicable notice requirement or grace period);

      (vii) Bankruptcy. The party, any Credit Support Provider of such party or
      any applicable Specified Entity of such party: --

            (1) is dissolved (other than pursuant to a consolidation,
            amalgamation or merger); (2) becomes insolvent or is unable to pay
            its debts or fails or admits in writing its inability generally to
            pay its debts as they become due; (3) makes a general assignment,
            arrangement or composition with or for the benefit of its creditors;
            (4) institutes or has instituted against it a proceeding seeking a
            judgement of insolvency or bankruptcy or any other relief under any
            bankruptcy or insolvency law or other similar law affecting
            creditors' rights, or a petition is presented for its winding-up or
            liquidation, and, in the case of any such proceeding or petition
            instituted or presented against it, such proceeding or petition (A)
            results in a judgement of insolvency or bankruptcy or the entry of
            an order for relief or the making of an order for its winding-up or
            liquidation or (B) is not dismissed, discharged, stayed or
            restrained in each case within 30 days of the institution or
            presentation thereof; (5) has a resolution passed for its
            winding-up, official management or liquidation (other than pursuant
            to a consolidation, amalgamation or merger); (6) seeks or becomes
            subject to the appointment of an administrator, provisional
            liquidator, conservator, receiver, trustee, custodian or other

            (7) has a secured party take possession of all or substantially all
            its assets or has a distress, execution, attachment, sequestration
            or other legal process levied, enforced or sued on or against all or
            substantially all its assets and such secured party maintains
            possession, or any such process is not dismissed, discharged, stayed
            or restrained, in each case within 30 days thereafter; (8) causes or
            is subject to any event with respect to it which, under the
            applicable laws of any jurisdiction, has an analogous effect to any
            of the events specified in clauses (1) to (7) (inclusive); or (9)
            takes any action in furtherance of, or indicating its consent to,
            approval of, or acquiescence in, any of the foregoing acts; or

      (viii) Merger Without Assumption. The party or any Credit Support Provider
      of such party consolidates or amalgamates with, or merges with or into, or
      transfers all or substantially all its assets to, another entity and, at
      the time of such consolidation, amalgamation, merger or transfer: --

            (1) the resulting, surviving or transferee entity fails to assume
            all the obligations of such party or such Credit Support Provider
            under this Agreement or any Credit Support Document to which it or
            its predecessor was a party by operation of law or pursuant to an
            agreement reasonably satisfactory to the other party to this
            Agreement; or

            (2) the benefits of any Credit Support Document fail to extend
            (without the consent of the other party) to the performance by such
            resulting, surviving or transferee entity of its obligations under
            this Agreement.

(b) Termination Events. The occurrence at any time with respect to a party or,
if applicable, any Credit Support Provider of such party or any Specified Entity
of such party of any event specified below constitutes an Illegality if the
event is specified in (i) below, a Tax Event if the event is specified in (ii)
below or a Tax Event Upon Merger if the event is specified in (iii) below, and,
if specified to be applicable, a Credit Event


                                       6
<PAGE>

Upon Merger if the event is specified pursuant to (iv) below or an Additional
Termination Event if the event is specified pursuant to (v) below: --

      (i) Illegality. Due to the adoption of, or any change in, any applicable
      law after the date on which a Transaction is entered into, or due to the
      promulgation of, or any change in, the interpretation by any court,
      tribunal or regulatory authority with competent jurisdiction of any
      applicable law after such date, it becomes unlawful (other than as a
      result of a breach by the party of Section 4(b)) for such party (which
      will be the Affected Party): --

            (1) to perform any absolute or contingent obligation to make a
            payment or delivery or to receive a payment or delivery in respect
            of such Transaction or to comply with any other material provision
            of this Agreement relating to such Transaction; or

            (2) to perform, or for any Credit Support Provider of such party to
            perform, any contingent or other obligation which the party (or such
            Credit Support Provider) has under any Credit Support Document
            relating to such Transaction;

      (ii) Tax Event. Due to (x) any action taken by a taxing authority, or
      brought in a court of competent jurisdiction, on or after the date on
      which a Transaction is entered into (regardless of whether such action is
      taken or brought with respect to a party to this Agreement) or (y) a
      Change in Tax Law, the party (which will be the Affected Party) will, or
      there is a substantial likelihood that it will, on the next succeeding
      Scheduled Payment Date (1) be required to pay to the other party an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount is required to be
      deducted or withheld for or on account of a Tax (except in respect of
      interest under Section 2(e), 6(d)(ii) or 6(e)) and no additional amount is
      required to be paid in respect of such Tax under Section 2(d)(i)(4) (other
      than by reason of Section 2(d)(i)(4)(A) or (B));

      (iii) Tax Event Upon Merger. The party (the "Burdened Party") on the next
      succeeding Scheduled Payment Date will either (1) be required to pay an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount has been deducted or
      withheld for or on account of any Indemnifiable Tax in respect of which
      the other party is not required to pay an additional amount (other than by
      reason of Section 2(d)(i)(4)(A) or (B)), in either case as a result of a
      party consolidating or amalgamating with, or merging with or into, or
      transferring all or substantially all its assets to, another entity (which
      will be the Affected Party) where such action does not constitute an event
      described in Section 5(a)(viii);

      (iv) Credit Event Upon Merger. If "Credit Event Upon Merger" is specified
      in the Schedule as applying to the party, such party ("X"), any Credit
      Support Provider of X or any applicable Specified Entity of X consolidates
      or amalgamates with, or merges with or into, or transfers all or
      substantially all its assets to, another entity and such action does not
      constitute an event described in Section 5(a)(viii) but the
      creditworthiness of the resulting, surviving or transferee entity is
      materially weaker than that of X, such Credit Support Provider or such
      Specified Entity, as the case may be, immediately prior to such action
      (and, in such event, X or its successor or transferee, as appropriate,
      will be the Affected Party); or

      (v) Additional Termination Event. If any "Additional Termination Event" is
      specified in the Schedule or any Confirmation as applying, the occurrence
      of such event (and, in such event, the Affected Party or Affected Parties
      shall be as specified for such Additional Termination Event in the
      Schedule or such Confirmation).

(c) Event of Default and Illegality. If an event or circumstance which would
otherwise constitute or give rise to an Event of Default also constitutes an
Illegality, it will be treated as an Illegality and will not constitute an Event
of Default.


                                       7

6. Early Termination

(a) Right to Terminate Following Event of Default. If at any time an Event of
Default with respect to a party (the "Defaulting Party") has occurred and is
then continuing, the other party (the "Non-defaulting Party") may, by not more
than 20 days notice to the Defaulting Party specifying the relevant Event of
Default designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however,
"Automatic Early Termination" is specified in the Schedule as applying to a
party, then an Early Termination Date in respect of all outstanding Transactions
will occur immediately upon the occurrence with respect to such party of an
Event of Default specified in Section 5(a)(vii)(1), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the
institution of the relevant proceeding or the presentation of the relevant
petition upon the occurrence with respect to such party of an Event of Default
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b) Right to Terminate Following Termination Event.

      (i) Notice. If a Termination Event occurs, an Affected Party will,
      promptly upon becoming aware of it, notify the other party, specifying the
      nature of that Termination Event and each Affected Transaction and will
      also give such other information about that Termination Event as the other
      party may reasonably require.

      (ii) Transfer to Avoid Termination Event. If either an Illegality under
      Section 5(b)(i)(1) or a Tax Event occurs and there is only one Affected
      Party, or if a Tax Event Upon Merger occurs and the Burdened Party is the
      Affected Party, the Affected Party will, as a condition to its right to
      designate an Early Termination Date under Section 6(b)(iv), use all
      reasonable efforts (which will not require such party to incur a loss,
      excluding immaterial, incidental expenses) to transfer within 20 days
      after it gives notice under Section 6(b)(i) all its rights and obligations
      under this Agreement in respect of the Affected Transactions to another of
      its Offices or Affiliates so that such Termination Event ceases to exist.

      If the Affected Party is not able to make such a transfer it will give
      notice to the other party to that effect within such 20 day period,
      whereupon the other party may effect such a transfer within 30 days after
      the notice is given under Section 6(b)(i).

      Any such transfer by a party under this Section 6(b)(ii) will be subject
      to and conditional upon the prior written consent of the other party,
      which consent will not be withheld if such other party's policies in
      effect at such time would permit it to enter into transactions with the
      transferee on the terms proposed.

      (iii) Two Affected Parties. If an Illegality under Section 5(b)(i)(1) or a
      Tax Event occurs and there are two Affected Parties, each party will use
      all reasonable efforts to reach agreement within 30 days after notice
      thereof is given under Section 6(b)(i) on action to avoid that Termination
      Event.

      (iv) Right to Terminate. If: --

            (1) a transfer under Section 6(b)(ii) or an agreement under Section
            6(b)(iii), as the case may be, has not been effected with respect to
            all Affected Transactions within 30 days after an Affected Party
            gives notice under Section 6(b)(i); or

            (2) an Illegality under Section 5(b)(i)(2), a Credit Event Upon
            Merger or an Additional Termination Event occurs, or a Tax Event
            Upon Merger occurs and the Burdened Party is not the Affected Party,

      either party in the case of an Illegality, the Burdened Party in the case
      of a Tax Event Upon Merger, any Affected Party in the case of a Tax Event
      or an Additional Termination Event if there is more than one Affected
      Party, or the party which is not the Affected Party in the case of a
      Credit Event Upon Merger or an Additional Termination Event if there is
      only one Affected Party may, by not more than 20 days notice to the other
      party and provided that the relevant Termination Event is then


                                       8
<PAGE>

      continuing, designate a day not earlier than the day such notice is
      effective as an Early Termination Date in respect of all Affected
      Transactions.

(c) Effect of Designation.

      (i) If notice designating an Early Termination Date is given under Section
      6(a) or (b), the Early Termination Date will occur on the date so
      designated, whether or not the relevant Event of Default or Termination
      Event is then continuing.

      (ii) Upon the occurrence of effective designation of an Early Termination
      Date, no further payments or deliveries under Section 2(a)(i) or 2(e) in
      respect of the Terminated Transactions will be required to be made, but
      without prejudice to the other provisions of this Agreement. The amount,
      if any, payable in respect of an Early Termination Date shall be
      determined pursuant to Section 6(e).

(d) Calculations.

      (i) Statement. On or as soon as reasonably practicable following the
      occurrence of an Early Termination Date, each party will make the
      calculations on its part, if any, contemplated by Section 6(e) and will
      provide to the other party a statement (1) showing, in reasonable detail,
      such calculations (including all relevant quotations and specifying any
      amount payable under Section 6(e)) and (2) giving details of the relevant
      account to which any amount payable to it is to be paid. In the absence of
      written confirmation from the source of a quotation obtained in
      determining a Market Quotation, the records of the party obtaining such
      quotation will be conclusive evidence of the existence and accuracy of
      such quotation.

      (ii) Payment Date. An amount calculated as being due in respect of any
      Early Termination Date under Section 6(e) will be payable on the day that
      notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated or occurs as a result of an Event of
      Default) and on the day which is two Local Business Days after the day on
      which notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated as a result of a Termination Event).
      Such amount will be paid together with (to the extent permitted under
      applicable law) interest thereon (before as well as after judgment) in
      the Termination Currency, from (and including) the relevant Early
      Termination Date to (but excluding) the date such amount is paid, at the
      Applicable Rate. Such interest will be calculated on the basis of daily
      compounding and the actual number of days elapsed.

(e) Payments on Early Termination. If an Early Termination Date occurs, the
following provisions shall apply based on the parties' election in the Schedule
of a payment measure, either "Market Quotation" or "Loss", and a payment method,
either the "First Method" or the "Second Method". If the parties fail to
designate a payment measure or payment method in the Schedule, it will be deemed
that "Market Quotation" or the "Second Method", as the case may be, shall apply.
The amount, if any, payable in respect of an Early Termination Date and
determined pursuant to this Section will be subject to any Set-off.

      (i) Events of Default. If the Early Termination Date results from an Event
      of Default: --

            (1) First Method and Market Quotation. If the First Method and
            Market Quotation apply, the Defaulting Party will pay to the
            Non-defaulting Party the excess, if a positive number, of (A) the
            sum of the Settlement Amount (determined by the Non-defaulting
            Party) in respect of the Terminated Transactions and the Termination
            Currency Equivalent of the Unpaid Amounts owing to the
            Non-defaulting Party over (B) the Termination Currency Equivalent of
            the Unpaid Amounts owing to the Defaulting Party.

            (2) First Method and Loss. If the First Method and Loss apply, the
            Defaulting Party will pay to the Non-defaulting Party, if a positive
            number, the Non-defaulting Party's Loss in respect of this
            Agreement.

            (3) Second Method and Market Quotation. If the Second Method and
            Market Quotation apply, an amount will be payable equal to (A) the
            sum of the Settlement Amount (determined by the


                                       9
<PAGE>

            Non-defaulting Party) in respect of the Terminated Transactions and
            the Termination Currency Equivalent of the Unpaid Amounts owing to
            the Non-defaulting Party less (B) the Termination Currency
            Equivalent of the Unpaid Amounts owing to the Defaulting Party. If
            that amount is a positive number, the Defaulting Party will pay it
            to the Non-defaulting Party; if it is a negative number, the
            Non-defaulting Party will pay the absolute value of that amount to
            the Defaulting Party.

            (4) Second Method and Loss. If the Second Method and Loss apply, an
            amount will be payable equal to the Non-defaulting Party's Loss in
            respect of this Agreement. If that amount is a positive number, the
            Defaulting Party will pay it to the Non-defaulting Party; if it is a
            negative number, the Non-defaulting Party will pay the absolute
            value of that amount to the Defaulting Party.

      (iii) Termination Events. If the Early Termination Date results from a
      Termination Event: --

            (1) One Affected Party. If there is one Affected Party, the amount
            payable will be determined in accordance with Section 6(e)(i)(3), if
            Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
            except that, in either case, references to the Defaulting Party and
            to the Non-defaulting Party will be deemed to be references to the
            Affected Party and the party which is not the Affected Party,
            respectively, and, if Loss applies and fewer than all the
            Transactions are being terminated, Loss shall be calculated in
            respect of all Terminated Transactions.

            (2) Two Affected Parties. If there are two Affected Parties: --

                  (A) if Market Quotation applies, each party will determine a
                  Settlement Amount in respect of the Terminated Transactions,
                  and an amount will be payable equal to (I) the sum of (a)
                  one-half of the difference between the Settlement Amount of
                  the party with the higher Settlement Amount ("X") and the
                  Settlement Amount of the party with the lower Settlement
                  Amount ("Y") and (b) the Termination Currency Equivalent of
                  the Unpaid Amounts owing to X less (II) the Termination
                  Currency Equivalent of the Unpaid Amounts owing to Y; and

                  (B) if Loss applies, each party will determine its Loss in
                  respect of this Agreement (or, if fewer than all the
                  Transactions are being terminated, in respect of all
                  Terminated Transactions) and an amount will be payable equal
                  to one-half of the difference between the Loss of the party
                  with the higher Loss ("X") and the Loss of the party with the
                  lower Loss ("Y").

            If the amount payable is a positive number, Y will pay it to X; if
            it is a negative number, X will pay the absolute value of that
            amount to Y.

      (iii) Adjustment for Bankruptcy. In circumstances where an Early
      Termination Date occurs because "Automatic Early Termination" applies in
      respect of a party, the amount determined under this Section 6(e) will be
      subject to such adjustments as are appropriate and permitted by law to
      reflect any payments or deliveries made by one party to the other under
      this Agreement (and retained by such other party) during the period from
      the relevant Early Termination Date to the date for payment determined
      under Section 6(d)(ii).

      (iv) Pre-Estimate. The parties agree that if Market Quotation applies an
      amount recoverable under this Section 6(e) is a reasonable pre-estimate of
      loss and not a penalty. Such amount is payable for the loss of bargain and
      the loss of protection against future risks and except as otherwise
      provided in this Agreement neither party will be entitled to recover any
      additional damages as a consequence of such losses.


                                       10

7. Transfer

Subject to Section 6(b)(ii), neither this Agreement nor any interest or
obligation in or under this Agreement may be transferred (whether by way of
security or otherwise) by either party without the prior written consent of the
other party, except that: --

(a) a party may make such a transfer of this Agreement pursuant to a
consolidation or amalgamation with, or merger with or into, or transfer of all
or substantially all its assets to, another entity (but without prejudice to any
other right or remedy under this Agreement); and

(b) a party may make such a transfer of all or any part of its interest in any
amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void.

8. Contractual Currency

(a) Payment in the Contractual Currency. Each payment under this Agreement will
be made in the relevant currency specified in this Agreement for that payment
(the "Contractual Currency"). To the extent permitted by applicable law, any
obligation to make payments under this Agreement in the Contractual Currency
will not be discharged or satisfied by any tender in any currency other than the
Contractual Currency, except to the extent such tender results in the actual
receipt by the party to which payment is owed, acting in a reasonable manner and
in good faith in converting the currency so tendered into the Contractual
Currency, of the full amount in the Contractual Currency of all amounts payable
in respect of this Agreement. If for any reason the amount in the Contractual
Currency so received falls short of the amount in the Contractual Currency
payable in respect of this Agreement, the party required to make the payment
will, to the extent permitted by applicable law, immediately pay such additional
amount in the Contractual Currency as may be necessary to compensate for the
shortfall. If for any reason the amount in the Contractual Currency so received
exceeds the amount in the Contractual Currency payable in respect of this
Agreement, the party receiving the payment will refund promptly the amount of
such excess.

(b) Judgments. To the extent permitted by applicable law, if any judgment or
order expressed in a currency other than the Contractual Currency is rendered
(i) for the payment of any amount owing in respect of this Agreement, (ii) for
the payment of any amount relating to any early termination in respect of this
Agreement or (iii) in respect of a judgment or order of another court for the
payment of any amount described in (i) or (ii) above, the party seeking
recovery, after recovery in full of the aggregate amount to which such party is
entitled pursuant to the judgment or order, will be entitled to receive
immediately from the other party the amount of any shortfall of the Contractual
Currency received by such party as a consequence of sums paid in such other
currency and will refund promptly to the other party any excess of the
Contractual Currency received by such party as a consequence of sums paid in
such other currency if such shortfall or such excess arises or results from any
variation between the rate of exchange at which the Contractual Currency is
converted into the currency of the judgment or order for the purposes of such
judgment or order and the rate of exchange at which such party is able, acting
in a reasonable manner and in good faith in converting the currency received
into the Contractual Currency, to purchase the Contractual Currency with the
amount of the currency of the judgment or order actually received by such party.
The term "rate of exchange" includes, without limitation, any premiums and costs
of exchange payable in connection with the purchase of or conversion into the
Contractual Currency.

(c) Separate Indemnities. To the extent permitted by applicable law, these
indemnities constitute separate and independent obligations from the other
obligations in this Agreement, will be enforceable as separate and independent
causes of action, will apply notwithstanding any indulgence granted by the party
to which any payment is owed and will not be affected by judgment being obtained
or claim or proof being made for any other sums payable in respect of this
Agreement.

(d) Evidence of Loss. For the purpose of this Section 8, it will be sufficient
for a party to demonstrate that it would have suffered a loss had an actual
exchange or purchase been made.


                                       11

9. Miscellaneous

(a) Entire Agreement. This Agreement constitutes the entire agreement and
understanding of the parties with respect to its subject matter and supersedes
all oral communication and prior writings with respect thereto.

(b) Amendments. No amendment, modification or waiver in respect of this
Agreement will be effective unless in writing (including a writing evidenced by
a facsimile transmission) and executed by each of the parties or confirmed by an
exchange of telexes or electronic messages on an electronic messaging system.

(c) Survival of Obligations. Without prejudice to Sections 2(a)(iii) and
6(c)(ii), the obligations of the parties under this Agreement will survive the
termination of any Transaction.

(d) Remedies Cumulative. Except as provided in this Agreement, the rights,
powers, remedies and privileges provided in this Agreement are cumulative and
not exclusive of any rights, powers, remedies and privileges provided by law.

(e) Counterparts and Confirmations.

      (i) This Agreement (and each amendment, modification and waiver in respect
      of it) may be executed and delivered in counterparts (including by
      facsimile transmission), each of which will be deemed an original.

      (ii) The parties intend that they are legally bound by the terms of each
      Transaction from the moment they agree to those terms (whether orally or
      otherwise). A Confirmation shall be entered into as soon as practicable
      and may be executed and delivered in counterparts (including by facsimile
      transmission) or be created by an exchange of telexes or by an exchange of
      electronic messages on an electronic messaging system, which in each case
      will be sufficient for all purposes to evidence a binding supplement to
      this Agreement. The parties will specify therein or through another
      effective means that any such counterpart, telex or electronic message
      constitutes a Confirmation.

(f) No Waiver of Rights. A failure or delay in exercising any right, power or
privilege in respect of this Agreement will not be presumed to operate as a
waiver, and a single or partial exercise of any right, power or privilege will
not be presumed to preclude any subsequent or further exercise of that right,
power or privilege or the exercise of any other right, power or privilege.

(g) Headings. The headings used in this Agreement are for convenience of
reference only and are not to affect the construction of or to be taken into
consideration in interpreting this Agreement.

10. Offices; Multibranch Parties

(a) If Section 10(a) is specified in the Schedule as applying, each party that
enters into a Transaction through an Office other than its head or home office
represents to the other party that, notwithstanding the place of booking office
or jurisdiction of incorporation or organisation of such party, the obligations
of such party are the same as if it had entered into the Transaction through its
head or home office. This representation will be deemed to be repeated by such
party on each date on which a Transaction is entered into.

(b) Neither party may change the Office through which it makes and receives
payments or deliveries for the purpose of Transaction without prior written
consent of the other party.

(c) If a party is specified as a Multibranch Party in the Schedule, such
Multibranch Party may make and receive payments or deliveries under any
Transaction through any Office listed in the Schedule, and the Office through
which it makes and receives payments or deliveries with respect to a Transaction
will be specified in the relevant Confirmation.

11. Expenses

A Defaulting Party will, on demand, indemnify and hold harmless the other party
for and against all reasonable out-of-pocket expenses, including legal fees and
Stamp Tax, incurred by such other party by reason of the enforcement and
protection of its rights under this Agreement or any Credit Support Document


                                       12
<PAGE>

to which the Defaulting Party is a party or by reason of the early termination
of any Transaction, including, but not limited to, costs of collection.

12. Notices

(a) Effectiveness. Any notice or other communication in respect of this
Agreement may be given in any manner set forth below (except that a notice or
other communication under Section 5 or 6 may not be given by facsimile
transmission or electronic messaging system) to the address or number or in
accordance with the electronic messaging system details provided (see the
Schedule) and will be deemed effective as indicated: --

      (i) if in writing and delivered in person or by courier, on the date it is
      delivered;

      (ii) if sent by telex, on the date the recipient's answerback is received;

      (iii) if sent by facsimile transmission, on the date that transmission is
      received by a responsible employee of the recipient in legible form (it
      being agreed that the burden of proving receipt will be on the sender and
      will not be met by a transmission report generated by the sender's
      facsimile machine);

      (iv) if sent by certified or registered mail (airmail, if overseas) or the
      equivalent (return receipt requested), on the date that mail is delivered
      or its delivery is attempted; or

      (v) if sent by electronic messaging system, on the date that electronic
      message is received,

unless the date of that delivery (or attempted delivery) or that receipt, as
applicable, is not a Local Business Day or that communication is delivered (or
attempted) or received, as applicable, after the close of business on a Local
Business Day, in which case that communication shall be deemed given and
effective on the first following day that is a Local Business Day.

(b) Change of Addresses. Either party may by notice to the other change the
address, telex or facsimile number or electronic messaging system details at
which notices or other communications are to be given to it.

13. Governing Law and Jurisdiction

(a) Governing Law. This Agreement will be governed by and construed in
accordance with the law specified an the Schedule.

(b) Jurisdiction. With respect to any suit, action or proceedings relating to
this Agreement ("Proceedings"), each party irrevocably: --

      (i) submits to the jurisdiction of the English courts, if this Agreement
      is expressed to be governed by English law, or to the non-exclusive
      jurisdiction of the courts of the State of New York and the United States
      District Court located in the Borough of Manhattan an New York City, if
      this Agreement is expressed to be governed by the laws of the State of New
      York; and

      (ii) waives any objection which it may have at any time to the laying of
      venue of any Proceedings brought in any such court, waives any claim that
      such Proceedings have been brought in an inconvenient forum and further
      waives the right to object, with respect to such Proceedings, that such
      court does not have any jurisdiction over such party.

Nothing in this Agreement precludes either party from bringing Proceedings in
any other jurisdiction (outside, if this Agreement is expressed to be governed
by English law, the Contracting States, as defined in Section 1(3) of the Civil
Jurisdiction and Judgments Act 1982 or any modification, extension or
re-enactment thereof for the time being in force) nor will the bringing of
Proceedings in any one or more jurisdictions preclude the bringing of
Proceedings in any other jurisdiction.

(c) Service of Process. Each party irrevocably appoints the Process Agent (if
any) specified opposite its name in the Schedule to receive, for it and on its
behalf, service of process in any Proceedings. If for any


                                       13
<PAGE>

reason any party's Process Agent is unable to act as such, such party will
promptly notify the other party and within 30 days appoint a substitute process
agent acceptable to the other party. The parties irrevocably consent to service
of process given in the manner provided for notices in Section 12. Nothing in
this Agreement will affect the right of either party to serve process in any
other manner permitted by law.

(d) Waiver of immunities. Each party irrevocably waives, to the fullest extent
permitted by applicable law, with respect to itself and its revenues and assets
(irrespective of their use or intended use), all immunity on the grounds of
sovereignty or other similar grounds from (i) suit, (ii) jurisdiction of any
court, (iii) relief by way of injunction, order for specific performance or for
recovery of property, (iv) attachment of its assets (whether before or after
judgment) and (v) execution or enforcement of any judgment to which it or its
revenues or assets might otherwise be entitled in any Proceedings in the courts
of any jurisdiction and irrevocably agrees, to the extent permitted by
applicable law, that it will not claim any such immunity in any Proceedings.

respect of a payment under this Agreement but for a present or former connection
between the jurisdiction of the government or taxation authority imposing such
Tax and the recipient of such payment or a person related to such recipient
(including, without limitation, a connection arising from such recipient or
related person being or having been a citizen or resident of such jurisdiction,
or being or having been organised, present or engaged in a trade or business in
such jurisdiction, or having or having had a permanent establishment or fixed
place of business in such jurisdiction, but excluding a connection arising
solely from such recipient or related person having executed, delivered,
performed its obligations or received a payment under, or enforced, this
Agreement or a Credit Support Document).

"law" includes any treaty, law, rule or regulation (as modified, in the case of
tax matters, by the practice of any relevant governmental revenue authority) and
"lawful" and "unlawful" will be construed accordingly.

"Local Business Day" means, subject to the Schedule, a day on which commercial
banks are open for business (including dealings in foreign exchange and foreign
currency deposits) (a) in relation to any obligation under Section 2(a)(i), in
the place(s) specified in the relevant Confirmation or, if not so specified, as
otherwise agreed by the parties in writing or determined pursuant to provisions
contained, or incorporated by reference, in this Agreement, (b) in relation to
any other payment, in the place where the relevant account is located and, if
different, in the principal financial centre, if any, of the currency of such
payment, (c) in relation to any notice or other communication, including notice
contemplated under Section 5(a)(i), in the city specified in the address for
notice provided by the recipient and, in the case of a notice contemplated by
Section 2(b), in the place where the relevant new account is to be located and
(d) in relation to Section 5(a)(v)(2), in the relevant locations for performance
with respect to such Specified Transaction.

"Loss" means, with respect to this Agreement or one or more Terminated
Transactions, as the case may be, and a party, the Termination Currency
Equivalent of an amount that party reasonably determines in good faith to be its
total losses and costs (or gain, in which case expressed as a negative number)
in connection with this Agreement or that Terminated Transaction or group of
Terminated Transactions, as the case may be, including any loss of bargain, cost
of funding or, at the election of such party but without duplication, loss or
cost incurred as a result of its terminating, liquidating, obtaining or
reestablishing any hedge or related trading position (or any gain resulting from
any of them). Loss includes losses and costs (or gains) in respect of any
payment or delivery required to have been made (assuming satisfaction of each
applicable condition precedent) on or before the relevant Early Termination Date
and not made, except, so as to avoid duplication, if Section 6(e)(i)(1) or (3)
or 6(e)(ii)(2)(A) applies. Loss does not include a party's legal fees and
out-of-pocket expenses referred to under Section 11. A party will determine its
Loss as of the relevant Early Termination Date, or, if that is not reasonably
practicable, as of the earliest date thereafter as is reasonably practicable. A
party may (but need not) determine its Loss by reference to quotations of
relevant rates or prices from one or more leading dealers in the relevant
markets.

"Market Quotation" means, with respect to one or more Terminated Transactions
and a party making the determination, an amount determined on the basis of
quotations from Reference Market-makers. Each quotation will be for an amount,
if any, that would be paid to such party (expressed as a negative number) or by
such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document
with respect to the obligations of such party) and the quoting Reference
Market-maker to enter into a transaction (the "Replacement Transaction") that
would have the effect of preserving for such party the economic equivalent of
any payment or delivery (whether the underlying obligation was absolute or
contingent and assuming the satisfaction of each applicable condition precedent)
by the parties under Section 2(a)(i) in respect of such Terminated Transaction
or group of Terminated Transactions that would, but for the occurrence of the
relevant Early Termination Date, have


                                       15
<PAGE>

been required after that date. For this purpose, Unpaid Amounts in respect of
the Terminated Transaction or group or Terminated Transactions are to be
excluded but, without limitation, any payment or delivery that would, but for
the relevant Early Termination Date, have been required (assuming satisfaction
of each applicable condition precedent) after that Early Termination Date is to
be included. The Replacement Transaction would be subject to such documentation
as such party and the Reference Market-maker may, in good faith, agree. The
party making the determination (or its agent) will request each Reference
Market-maker to provide its quotation to the extent reasonably practicable as of
the same day and time (without regard to different time zones) on or as soon as
reasonably practicable after the relevant Early Termination Date. The day and
time as of which those quotations are to be obtained will be selected in good
faith by the party obliged to make a determination under Section 6(e), and, if
each party is so obliged, after consultation with the other. If more than three
quotations are provided, the Market Quotation will be the arithmetic mean of the
quotations, without regard to the quotations having the highest and lowest
values. If exactly three such quotations are provided, the Market Quotation will
be the quotation remaining after disregarding the highest and lowest quotations.
For this purpose, if more than one quotation has the same highest value or
lowest value, then one of such quotations shall be disregarded. If fewer than
three quotations are provided, it will be deemed that the Market Quotation in
respect of such Terminated Transaction or group of Terminated Transactions
cannot be determined.

"Non-default Rate" means a rate per annum equal to the cost (without proof or
evidence of any actual cost) to the Non-defaulting Party (as certified by it) if
it were to fund the relevant amount.

"Office" means a branch or office of a party, which may be such party's head or
home office.

selected by the party determining a Market Quotation in good faith (a) from
among dealers of the highest credit standing which satisfy all the criteria that
such party applies generally at the time in deciding whether to offer or to make
an extension of credit and (b) to the extent practicable, from among such
dealers having an office in the same city.

"Relevant Jurisdiction" means, with respect to a party, the jurisdictions (a) in
which the party is incorporated, organised, managed and controlled or considered
to have its seat, (b) where an Office through which the party is acting for
purposes of this Agreement is located, (c) in which the party executes this
Agreement and (d) in relation to any payment, from or through which such payment
is made.

"Scheduled Payment Date" means a date on which a payment or delivery is to be
made under Section 2(a)(i) with respect to a Transaction.

"Set-off" means set-off, offset, combination of accounts, right of retention or
withholding or similar right or requirement to which the payer of an amount
under Section 6 is entitled or subject (whether arising under this Agreement,
another contract, applicable law or otherwise) that is exercised by, or imposed
on, such payer.

"Settlement Amount" means, with respect to a party and any Early Termination
Date, the sum of: --

(a) the Termination Currency Equivalent of the Market Quotations (whether
positive or negative) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation is determined; and

(b) such party's Loss (whether positive or negative and without reference to any
Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not (in
the reasonable belief of the party making the determination) produce a
commercially reasonable result.

"Specified Entity" has the meaning specified in the Schedule.


                                       16

the Termination Currency, such Termination Currency amount and, in respect of
any amount denominated in a currency other than the Termination Currency (the
"Other Currency"), the amount in the Termination Currency determined by the
party making the relevant determination as being required to purchase such
amount of such Other Currency as at the relevant Early Termination Date, or, if
the relevant Market Quotation or Loss (as the case may be), is determined as of
a later date, that later date, with the Termination Currency at the rate equal
to the spot exchange rate of the foreign exchange agent (selected as provided
below) for the purchase of such Other Currency with the Termination Currency at
or about 11:00 a.m. (in the city in which such foreign exchange agent is
located) on such date as would be customary for the determination of such a rate
for the purchase of such Other Currency for value on the relevant Early
Termination Date or that later date. The foreign exchange agent will, if only
one party is obliged to make a determination under Section 6(e), be selected in
good faith by that party and otherwise will be agreed by the parties.

                                    SCHEDULE

                                     to the

                              ISDA Master Agreement

                                   dated as of

                 between WESTPAC BANKING CORPORATION ("Party A")

                    WESTPAC SECURITIES ADMINISTRATION LIMITED
                  as trustee of WST Series 1998-1G ("Party B")

                                       and

         WESTPAC SECURITISATION MANAGEMENT PTY LIMITED ("Trust Manager")

Part 1

                             Termination Provisions

In this Agreement:-

(a)   "Specified Entity" is not applicable in relation to Party A and Party B.

(b)   The "Breach of Agreement", Credit Support Default" and "Misrepresentation"
      provisions of Section 5(a)(ii), (iii) and (iv) will not apply to Party A
      and Party B.

(c)   The "Default under Specified Transaction" and "Cross Default" provisions
      of Section 5(a)(v) and (vi) will not apply to Party A and Party B.

(d)   "Termination Currency" means Australian Dollars.

(e)   The "'Bankruptcy" provisions of Section 5(a)(vii) are replaced by "An
      Insolvency Event has occurred in respect of the party". The occurrence of
      an Insolvency Event in respect of Party B in its personal capacity will
      not constitute an Event of Default provided that within thirty Business
      Days of that occurrence, Party A and Party B are able to procure the
      novation of this Agreement and all Transactions to a third party in
      respect of which the Designated Rating Agencies confirm that the novation
      will not cause a reduction or withdrawal of the rating of the Notes.

(f)   Section 5(a)(i) is amended to replace "third" with "tenth".

(g)   The "Merger Without Assumption" provisions of Section 5(a)(viii) will not
      apply to Party A and Party B. The provisions of Sections 5(b)(ii)("Tax
      Event") and 5(b)(iii)("Tax Event Upon Merger") will not apply to Party A
      and Party B. The "Credit Event Upon Merger" provisions of Section 5(b)(iv)
      will not apply to Party A and Party B.

(h)   An "Additional Termination Event" , set out in Part 5(i)(a) and (d) of
      this Schedule, will apply.

(i)   The "Automatic Early Termination" provision of Section 6(a) will not apply
      to Party A and Party B. Any event which, upon its occurrence, constitutes
      an Event of Default, is deemed not to be an essential term of the
      Transaction so that the occurrence of any Event of Default shall not be
      implied to constitute a repudiation of the Agreement. This does not in any
      way restrict or limit the right of a Non-Defaulting Party under section
      6(a) to terminate following an Event of Default.

<PAGE>

(j)   In the "Transfer to Avoid Termination Event" provision of Section
      6(b)(ii), after the words "another of its Offices or Affiliates" on the
      seventh line add "(in respect of which the Designated Rating Agencies
      confirm that the transfer will not cause a reduction or withdrawal of the
      rating of the Notes)".

      Agreement:-

            (i)   Subject to paragraphs a) and b) below, Loss will apply

            (ii)  The Second Method will apply

      a)    In respect of any Transaction that is described in its Confirmation
            as a "Variable Rate Basis Swap", the Loss of each party entitled to
            make a determination of its Loss under Section 6(e) will be deemed
            to be zero; and

      b)    In respect of any Transaction that is, described in its Confirmation
            as a "Fixed Rate Basis Swap", the Loss of each party entitled to
            make a determination of its Loss under Section 6(e) will be deemed
            to be that amount that would result from the application of the
            "Market Quotation" payment measure to the Transaction.

(l)   In the "Transfer" provision of Section 7, add at the end of paragraph (a)
      after the closing parenthesis following the word "Agreement";

            "provided, in respect of Party A, that such other entity is an
            entity in respect of which the Designated Rating Agencies confirm
            that the transfer will not cause a reduction or withdrawal of the
            rating of the Notes";

      and add a new paragraph (c);

      "(c)  Party B may transfer to a Successor Trustee (as defined below) or to
            avoid an Illegality as specified in Section 5(b)(i)".

(m)   Add a new paragraph to Section 7, immediately below paragraph (c):

      In the event that a trustee is appointed as a successor to Party B under
      the Trust Deed ("Successor Trustee"), Party A undertakes that it shall
      (unless, at the time the Successor Trustee is so appointed, Party A is
      entitled to terminate the Transaction under Section 6, in which case it
      may) novate to the Successor Trustee the Transaction on the same terms or
      on other terms to be agreed between Party A, Party B and the Successor
      Trustee, and give written notice to the Designated Rating Agencies of such
      novation.

(n)   Add a new Section 2(f) Trustee Provisions:

      Party B enters into this Agreement in its capacity as Trustee of the
      Trust. Clause 33.16 of the Trust Deed applies to this Agreement as if set
      out in full. Clause 15 of the Security Trust Deed shall apply to govern
      Party A's priority to moneys received from the sale of Assets or other
      enforcement of the Charge under the Security Trust Deed (each as defined
      in the Security Trust Deed).

(o)   In the "Amendment" provision of Section 9(b) add at the end", and notified
      in writing to the Designated Rating Agencies".

            Transaction (other than, in respect of Party B, the trusts created
            pursuant to the Trust Deed) and has not given any charge over its
            assets, in the case of Party A, or the assets of the Trust (other

      Party B also represents to Party A (which representations will be deemed
      to be repeated by Party B on each date on which a Transaction is entered
      into) that:

      (i)   Trust Validly Created. The Trust has been validly created and is in
            existence at the date of this Agreement.

            Deed, the Security Trust Deed and any Security Interest (as defined
            in the Security Trust Deed) permitted under the Security Trust Deed,
            those assets are free from all other Security Interests."

(h)   Additional Covenant: In Section 4 add a new paragraph as follows:

      "(f)  Contracting as Principal. Party A will enter into all Transactions
            as principal and not otherwise and Party B will enter into
            Transaction in its capacity as trustee of the Trust and not
            otherwise."

(i)    (a)  In respect of any Transaction that is described in its
            Confirmation as a "Variable Rate Basis Swap", if at any time Party
            A's short-term credit rating is downgraded below A-1+ in the case of
            Standard & Poor's or A2 in the case of Moody's Investors Service
            Inc., it must, within 3 days of such downgrading (at its cost alone)
            either;

            i)    establish such collateralisation arrangements in support of
                  its obligations as are sufficient to allow the Designated
                  Rating Agencies to confirm that the downgrade will not cause a
                  reduction or withdrawal of the rating of the Notes; or

            ii)   procure the novation of this Agreement to a replacement Swap
                  Provider

<PAGE>

                  acceptable to the Designated Rating Agencies.

            The failure by Party A to establish the collateral arrangements
            described in i) above, or to procure the novation of this Agreement
            as described in ii) above will constitute an Additional Termination
            Event. For the purposes of this Additional Termination Event, Party
            A will be the Affected Party.

      (b)   In respect of any Transaction that is described in its Confirmation
            as a "Fixed Rate Basis Swap", if at any time Party A's short-term
            credit rating is downgraded below A-1+ in the case of Standard &
            Poor's or A2 in the case of Moody's Investors Service Inc., Party A
            must, within 3 days of such downgrading, pay to Party B the Swap
            Collateral Amount (determined from time to time in accordance with
            paragraph c) below), which amount Party B must lodge in Authorised
            Investments. For this purpose "Authorised Investments" are cash,
            bank accepted bills of exchange rated A1 by Standard & Poor's and P1
            by Moody's Investors Service Inc., or other forms of securities
            acceptable to the Designated Rating Agencies. Following the initial
            payment of a Swap Collateral Amount within 3 days of its downgrade,
            Party A will be obliged to pay any subsequent Swap Collateral Amount
            by each Payment Date in respect of which, on the relevant
            Determination Date, a Swap Collateral Amount is calculated as being
            payable in accordance with paragraph (c) below.

            If Party B determines that it will lodge the Swap Collateral Amount
            in a cash account, Party B must as soon as is practicable establish
            and maintain in the name of Party B an account with a Bank having a
            short-term credit rating of A-1+ from Standard & Poor's and P-1 from
            Moody's or which otherwise satisfies the requirements of those
            Designated Rating Agencies (the "Swap Collateral Account").

            Party B may only make withdrawals from the Swap Collateral Account
            or liquidate the Authorised Investments if directed to do so by the
            Trust Manager and then only for the purpose of:

            i)    entering into a substitute swap;

            ii)   refunding to Party A the amount of any reduction in the Swap
                  Collateral Amount as required to be held under the calculation
                  in paragraph (c) below;

            iii)  withdrawing any amount which has been incorrectly deposited
                  into the Collateral Account;

            iv)   paying financial institutions duty, bank accounts debit tax or
                  their equivalent payable in respect of the Collateral Account;
                  or

            v)    funding the amount of any payment due to be made by Party A
                  under this Agreement following the failure by Party A to make
                  that payment.

      (c)   For any Business Day, the "Swap Collateral Amount" in respect of a
            Transaction will be either (1) the amount calculated by Party A in
            accordance with sub-paragraphs i) - vi) below, or (2) such other
            higher amount as is required by Standard & Poor's to affirm the
            rating on the Notes.

            For the purposes of alternative (1) above, the Swap Collateral
            Amount will be calculated as follows:

            i)    A repricing profile of the loans to which the Transaction
                  relates will be run as at the close of business on the
                  previous Business Day.

            ii)   The repricing duration (weighted average repricing term) of
                  the profile will be calculated using a 5% constant prepayment
                  rate and the spot mid-market zero coupon yield curve, which is
                  derived from the average of the four major banks' mid-market
                  inter-bank swap curves.

<PAGE>

            iii)  The implied volatility for the term derived in ii) above will
                  be calculated using the Sydney Futures Exchange futures strip.

            iv)   The forward one month mid-market zero curve plus 5 basis
                  points will be derived.

            v)    A 99% degree of confidence will be applied to the zero curve
                  derived in iv) above (i.e 2.33 x volatility).

            vi)   The profile run under i) above will be marked-to-market using
                  the curve described in v) above.

            The difference between the market value of the outcome of step vi)
            and the Notional Value of the Transaction will represent the Swap
            Collateral Amount. Step vi) will be repeated on a monthly basis (on
            each Determination Date for the Transaction) following the first
            determination of the Swap Collateral Amount.

      (d)   The failure by Party A to establish the collateral arrangements
            described in b) above will, at the discretion of Party B, constitute
            an Additional Termination Event. For the purposes of this Additional
            Termination Event, Party A will be the Affected Party.

      (e)   If Party A has paid a Swap Collateral Amount to Party B in
            accordance with paragraph (b) above and an Early Termination Date is
            designated in respect of the Transaction to which that Swap
            Collateral Amount relates, then notwithstanding any other provision
            of this Agreement Party B will, as soon as is practicable, repay
            that Swap Collateral Amount to Party A.

(j)   Confirmations. Notwithstanding the provisions of Section 9(e)(ii), each
      Confirmation in respect of a Swap Transaction which is confirmed by
      electronic messaging system, an exchange of telexes or an exchange of
      facsimiles will be further evidenced by an original Confirmation signed by
      the parties, however any failure to sign an original Confirmation will not
      affect the validity or enforceability of any Swap Transaction.

(k)   Section 12 is amended as follows:-

      (i)   In Section 12(a), insert "and settlement instructions requiring
            payment to an entity other than the original counterparty" after
            "Section 5 or 6" in line 2.

      (ii)  Section 12(a)(iii) is replaced with:

            "(iii)if sent by facsimile transmission, on the date a transmission
                  report is produced by the machine from which the facsimile was
                  sent which indicates that the facsimile was sent in its
                  entirety to the facsimile number of the recipient notified for
                  the purpose of this Section, unless the recipient notifies the
                  sender within one Local Business Day of the facsimile being
                  sent that the facsimile was not received in its entirety and
                  in legible form."

(l)   In Section 14, the definition of "Market Quotation" is replaced with:

            ""Market Quotation" means, with respect to one or more Terminated
            Transactions and a party making the determination, an amount
            determined on the basis of quotations from Reference Market-makers.
            Each quotation will take into account any existing Credit Support
            Document with respect to the obligations of such party.

            Each quotation will be determined as the amount, if any, that would
            be paid to such party (expressed as a negative number) or by such
            party (expressed as a positive number) in consideration of an
            agreement between such party and the quoting Reference Market-maker
            to enter into a transaction (the "Replacement Transaction") 


8
<PAGE>

            that would have the effect of preserving for such party the economic
            equivalent of the Future Obligations of both parties.

            The Replacement Transaction would be subject to such documentation
            as such party and the Reference Market-maker may, in good faith,
            agree. The party making the determination (or its agent) will
            request each Reference Market-maker to provide its quotation to the
            extent reasonably practicable as of the same day and time (without
            regard to different time zones) on or as soon as reasonably
            practicable after the relevant Early Termination Date. The day and
            time as of which the quotation or quotations are to be obtained will
            be selected in good faith by the party obliged to make a
            determination under Section 6(e), and, if each party is so obliged,
            after consultation with the other.

            If more than three quotations are provided, the Market Quotation
            will be the arithmetic mean of the quotations, without regard to the
            quotations having the highest and lowest values. If exactly three
            such quotations are provided, the Market Quotation will be the
            quotation remaining after disregarding the highest and lowest
            quotations. For this purpose, if more than one quotation has the
            same highest value or lowest value, then one of such quotations
            shall be disregarded. If fewer than three quotations are provided,
            it will be deemed that the Market Quotation in respect of such
            Terminated Transaction or group of Terminated Transactions cannot be
            determined."

(m)   In Section 14, add new definitions:

            ""Future Obligations" means in respect of a Terminated Transaction,
            all payment or delivery obligations (whether the underlying
            obligation was absolute or contingent and assuming the satisfaction
            of each applicable condition precedent) of a party under Section
            2(a)(i) in respect of a Terminated Transaction or group of
            Terminated Transactions, that would, but for the occurrence of the
            relevant Early Termination Date, have been required after that date.
            (For this purpose, Unpaid Amounts in respect of the Terminated
            Transaction or group of Terminated Transactions are to be excluded
            but, without limitation, any payment or delivery that would, but for
            the relevant Early Termination Date, have been required (assuming
            satisfaction of each applicable condition precedent) after that
            Early Termination Date is to be included)."

      ""Trust Deed" means the Master Trust Deed dated 14 February 1997 and the
      WST Series 1997- 3 Notice dated 25 June 1997 between Party B, Party A and
      the Trust Manager, and each of the following expressions shall have the
      meanings given to them in the Trust Deed:

                  "Designated Rating Agency"
                  "Insolvency Event"
                  "Note"
                  "Security Trust Deed"
                  "Swap Provider"
                  "Trust"

(n)   Any reference to a:

      (i)   "Swap Transaction" in the 1991 ISDA Definitions is deemed to be a
            reference to a "Transaction" for the purpose of interpreting this
            Agreement or any Confirmation; and

      (ii)  "Transaction" in this Agreement or any Confirmation is deemed to be
            a reference to a "Swap Transaction" for the purpose of interpreting
            the 1991 ISDA Definitions.

(o)   The "September 1992 Australian Addendum No. 10 - (as amended in March
      1994) Netting of Schedule to Master Agreement of International Swaps and
      Derivatives Association, Inc." is 


9
<PAGE>

      deemed to be incorporated in this Agreement, except that in the event of
      any inconsistency between that addendum and this Schedule or any
      Confirmation, the Confirmation or this Schedule shall take precedence.

(p)   Trust Deed: The Parties acknowledge and agree that for the purposes of the
      Trust Deed, this Agreement is a "Hedge Agreement" and Party A is a "Swap
      Provider" and "Support Facility Provider".

(q)   Restricted Remedies

      (a)   (judgment) obtain a judgement for the payment of money or daParty B;

      (b)   (statutory demand) issue any demand under s459E(1) of the
            Corporations Law (or any analogous provision under any other law)
            against Party B;

      (c)   (winding up) apply for the winding up or dissolution of Party B;

      (d)   (execution) levy or enforce any distress or other execution to, on,
