                              Structural Overview

      Commonwealth Bank established the Medallion Programme pursuant to a
master trust deed dated 8 October 1997 between Securitisation Advisory Services
Pty. Limited as manager and Perpetual Trustee Company Limited as issuer
trustee. The master trust deed provides the general terms and structure for
securitization under the program. A series supplement between the issuer
trustee, the manager and Commonwealth Bank, as seller and servicer, sets out
the specific details of the Series 2000-1G Medallion Trust and the Class A-1
notes, which may vary from the terms set forth in the master trust deed. Each
securitization under the program is a separate transaction with a separate
trust. The assets of the Series 2000-1G Medallion Trust will not be available
to pay the obligations of any other trust, and the assets of other trusts will
not be available to pay the obligations of the Series 2000-1G Medallion Trust.
See "Description of the Trust."

      The Series 2000-1G Medallion Trust involves the securitization of housing
loans originated by Commonwealth Bank and secured by mortgages on residential
property located in Australia. Commonwealth Bank will equitably assign the
housing loans to the trust, which will in turn issue the floating rate Class A-
1 notes, along with the Class A-2 notes and Class-B notes, to fund the
acquisition of the housing loans.

      The issuer trustee will grant a floating charge over all of the assets of
the trust under the security trust deed in favor of P.T. Limited, as security
trustee, to secure the trust's payment obligations to the noteholders and its
other creditors. The floating charge is a first ranking charge over the assets
of the trust subject only to a prior interest in favor of the issuer trustee to
secure payment of certain expenses of the trust. A floating charge is a
security interest on a class of assets, but does not attach to specific assets
unless or until it crystalizes, which means it becomes a fixed charge. The
charge will crystalize if an event of default occurs under the security trust
deed (but in some cases will crystalize only over the assets affected by the
event of default). While the charge is a floating charge, the issuer trustee
may deal with the assets of the trust in accordance with the transaction
documents and, if it acts contrary to its duties, may be able to deal with the
assets of the trust in such a way as to prejudice the security trustee's
interest in the assets in breach of the transaction documents. [Once the
floating charge crystalizes, the issuer trustee will no longer be able to
dispose of or create interests in the assets of the trust without the consent
of the security trustee.] [Subject to discussions with S&P] For a description
of floating charges and crystallization see "The Security Trust Deed--Nature of
the Charge."

      Payments of interest and principal on the notes will come only from the
housing loans and other assets of the trust. The assets of the parties to the
transaction are not available to meet the payments of interest and principal on
the notes. If there are losses on the housing loans, the trust may not have
sufficient assets to repay the notes.

Credit Enhancements
      Payments of interest and principal on the Class A-1 notes will be
supported by the following forms of credit enhancement:

                                       12
<PAGE>

Subordination and Allocation of Losses
      The Class B notes will always be subordinated to the Class A-1 and A-2
notes in their right to receive interest payments. Prior to the occurrence of
an event of default and enforcement of the charge under the security trust
deed, the Class B notes will be subordinated to the Class A-1 and A-2 notes in
their right to receive principal payments only in the circumstances and to the
extent described in "Description of the Class A-1 Notes--Allocation of
Principal to Class A Notes and Class B Notes." Following the occurrence of an
event of default and enforcement of the charge under the security trust deed,
the Class B notes will be fully subordinated to the Class A-1 and A-2 notes in
their right to receive principal payments.

      The Class B notes will bear all losses on the housing loans before the
Class A-1 and A-2 notes. Any losses allocated to the Class A notes will be
allocated rateably between the Class A-1 and A-2 notes as described in
"Description of the Class A-1 Notes--Principal Charge-Offs." The support
provided by the Class B notes is intended to enhance the likelihood that the
Class A-1 and A-2 notes will receive expected quarterly payments of interest
and principal. The following chart describes the initial support provided by
the Class B notes:

      In certain circumstances, the issuer trustee may issue redraw bonds as
described in [ ]. If issued, redraw bonds will, prior to the occurrence of an
event of default and enforcement of the charge under the security trust deed,
rank equally with the Class A-1 and A-2 notes in their right to receive
interest payments and will rank in priority to the Class A-1 and A-2 notes in
their right to receive principal payments. Any losses allocated to the Class A
notes and redraw bonds will be allocated rateably between the Class A-1 and A-2
notes and the redraw bonds. Following the occurrence of an event of default and
enforcement of the charge under the security trust deed, redraw bonds will rank
equally with the Class A-1 and A-2 notes in their right to receive both
interest and principal payments.

Mortgage Insurance Policies
      Mortgage insurance policies issued by or transferred to Housing Loans
Insurance Corporation Pty Limited[, GE Capital Mortgage Insurance Corporation
(Australia) Pty Limited] and the Commonwealth of Australia will provide full
coverage for all principal due on each of the housing loans which had a loan to
value ratio greater than 80% at the time of origination.

      A master mortgage insurance policy issued by Housing Loans Insurance
Corporation Pty Limited will provide full coverage for all principal due on
each of the housing loans which had a loan to value ratio of less than 80% at
the time of origination.

Seller Deposit
      If Commonwealth Bank is assigned a short-term deposit credit rating by
Moody's of less than P1 or is assigned a

                                       13
<PAGE>

long term deposit credit rating by Standard & Poor's or Fitch IBCA of less than
BBB, or in each case, a lesser rating as agreed between the manager, the issuer
trustee and the relevant rating agency, it must deposit an amount in the
collections account on account of set-off risk determined with reference to,
and which may be less than, the balances of certain deposit accounts held by
borrowers with Commonwealth Bank. The amount of the seller deposit may be reset
on each determination date and adjusted on the following distribution date and
will be reduced to zero if the seller regains the required credit ratings. The
issuer trustee may use the seller deposit to meet liabilities of the seller in
relation to amounts set-off against the amount due on a housing loan which have
not been met within 20 business days of notice from the issuer trustee or the
manager.

      As an alternative to making the seller deposit, Commonwealth Bank may
implement other arrangements agreed with the rating agencies so that credit
ratings of the notes by those rating agencies will not be adversely affected.

Excess Interest Collections
      Any interest collections on the housing loans remaining after payments of
interest on the notes and the redraw bonds and the trust's expenses will be
available to cover any losses on the housing loans that are not covered by the
mortgage insurance policies.

Liquidity Enhancement
      To cover possible liquidity shortfalls in the payments of interest on the
notes and redraw bonds, the issuer trustee will, in certain circumstances, be
able to borrow funds under a liquidity facility to be provided by Commonwealth
Bank.

Redraws and Further Advances
      Under the terms of each variable rate housing loan, a borrower may,
subject to certain conditions, redraw previously prepaid principal. A borrower
may redraw an amount equal to the difference between the scheduled principal
balance, being its principal balance if no amount had been prepaid, of his or
her loan and the current principal balance of the loan. Commonwealth Bank may
also agree to make further advances to a borrower in excess of the scheduled
principal balance of his or her loan. Commonwealth Bank will be reimbursed for
any redraws, and for any further advances which exceed the scheduled principal
balance of a housing loan by no more than one scheduled monthly instalment on
the housing loan, that it advances to borrowers from principal collections on
the housing loans. Thus, the trust will have less funds available to pay
principal to the notes on the next distribution date, but will have a
corresponding greater amount of assets with which to make future payments. See
"Commonwealth Bank Residential Loan Program," "Description of The Class A-1
Notes--Redraws and Further Advances" and "Description of the Transaction
Documents--The Standby Redraw Facility."

Hedging Arrangements
      To hedge its interest rate and currency exposures, the issuer trustee
will enter into the following hedge arrangements:

 .   a basis swap to hedge the basis risk between the interest rate on the
    housing loans which accrue interest at a discretionary variable rate of
    interest and the floating rate obligations of the trust, including the
    issuer trustee's

                                       14
<PAGE>

    payment obligations under the currency swap;

 .   a fixed rate swap to hedge the basis risk between the interest rate on the
    housing loans which accrue interest at a fixed rate of interest and the
    floating rate obligations of the trust, including the issuer trustee's
    payment obligations under the currency swap; and

 .   a currency swap to hedge the currency risk and the basis risk between the
    collections on the housing loans and the amounts received by the issuer
    trustee under the basis swap and the fixed rate swap, which are denominated
    in Australian dollars and, in the case of the basis swap and fixed rate
    swap, calculated by reference to the Australian bank bill rate, and the
    obligation of the trust to pay interest and principal on the Class A-1
    notes, which are denominated in U.S. dollars and, in the case of interest,
    calculated by reference to LIBOR.

Optional Redemption
      The issuer trustee will, if the manager directs it to do so, redeem all
of the notes and redraw bonds on the earlier of the distribution date falling
in [ ] or the date when the current total outstanding principal balance of the
housing loans is less than 10% of the total outstanding principal balance of
the housing loans on [ ]. If the issuer trustee redeems the Class A-1 notes,
the Class A-1 noteholders will receive a payment equal to the outstanding
principal balance of the Class A-1 notes plus accrued interest on the
outstanding principal balance of the Class A-1 notes, unless Class A
noteholders and redraw bondholders owning 75% of the aggregate outstanding
principal balance of the Class A notes and redraw bonds consent to receiving
the outstanding principal balance of the Class A notes and redraw bonds, as
reduced by losses allocated against the Class A notes and redraw bonds, plus
accrued interest on the outstanding principal balance of the Class A notes and
redraw bonds.

                             The Housing Loan Pool

      The housing loan pool will consist of fixed rate and variable rate
residential housing loans secured by mortgages on owner occupied and non-owner
occupied one-to-four family residential properties. The housing loans will have
original terms to stated maturity of no more than 30 years. Commonwealth Bank
expects the pool of housing loans to have characteristics similar to the
following:

</TABLE>

      The original loan-to-value ratio of a housing loan is calculated by
comparing the initial principal amount of the housing loan to the most recent
valuation of the property that is currently securing the housing loan. Thus, if
collateral has been released from the mortgage securing a housing loan or if
the property securing the housing loan has been revalued, the original loan-to-
value ratio at the cut-off date may not reflect the loan-to-value ratio at the
origination of that housing loan.

      Before the issuance of the notes, housing loans may be added to or
removed from the housing loan pool. This addition or removal of housing loans
may result in changes in the housing loan pool characteristics shown in the
preceding table and could affect the weighted average lives and yields of the
notes. The seller will not add or remove any housing loans prior to the closing
date if this would result in a change of more than 5% in any of the
characteristics of the pool of housing loans described in this prospectus,
unless a revised prospectus is delivered to prospective investors.

      The seller has selected the housing loans from its pool of eligible loans
based on its selection criteria.

Withholding Tax

      Payments of principal and interest on the Class A-1 notes will be reduced
by any applicable withholding taxes. The issuer trustee is not obligated to pay
any additional amounts to the Class A-1 noteholders to cover any withholding
taxes. Under present law, the Class A-1 notes will not be subject to Australian
withholding tax if they are issued in accordance with certain prescribed
conditions and they are not held by associates of the issuer trustee or
Commonwealth Bank. The issuer trustee will seek to issue the Class A-1 notes in
a manner which will satisfy the conditions for an exemption from Australian
withholding tax. One of these conditions is that the issuer trustee must not
know or have reasonable grounds to suspect that a Class A-1 note, or an
interest in a Class A-1 note, was being, or would later be, acquired directly
or indirectly by associates of the issuer trustee or Commonwealth Bank.
Accordingly, persons who are associates of the issuer trustee or the
Commonwealth Bank, for the purposes of the Australian Income Tax Assessment Act
1936, should not acquire Class A-1 notes. See "Australian Tax Matters."

      If, by virtue of a change in law:

    .  the issuer trustee will be required to withhold or deduct amounts
       from payment of principal or interest to any class of noteholders or
       redraw bondholders due to taxes, duties, assessments or governmental
       charges; or

    .  if the issuer trustee ceases to receive the total amount of interest
       payable by borrowers on the housing loans due to taxes, duties,
       assessments or other governmental charges,

the manager may direct the issuer trustee to redeem all of the notes and redraw
bonds. If the issuer trustee redeems the Class A-1 notes, the Class A-1
noteholders will receive a payment equal to the outstanding principal balance
of the Class A-1 notes plus accrued interest on the outstanding principal
balance of the Class A-1 notes, unless Class A noteholders and redraw
bondholders owning 75% of the aggregate outstanding principal balance of the
Class A notes and redraw bonds consent to receiving the outstanding principal
balance of the Class A notes and redraw bonds, as reduced by losses allocated
against the Class A notes and redraw bonds, plus accrued interest on the
outstanding principal balance of the Class A notes and redraw bonds. However,
if the withholding or deduction relates only to the Class A-1 notes, Class A-1
noteholders owning 75% of the aggregate outstanding principal balance of the
Class A-1 notes may direct the issuer trustee not to redeem the notes and
redraw bonds. See "Description of the Class A-1 Notes--Redemption of the Notes
for Taxation or Other Reasons."

U.S. Tax Status
      In the opinion of Mayer, Brown & Platt, special tax counsel for the
manager, the Class A-1 notes will be characterized as debt for U.S. federal
income tax purposes. Each Class A-1 noteholder, by acceptance of a Class A-1
note, agrees to treat the notes as indebtedness. See "United States Federal
Income Tax Matters."

Legal Investment
      The Class A-1 notes will not constitute "mortgage-related securities" for
the purposes of the Secondary Mortgage Market Enhancement Act of 1984. No

                                       17
<PAGE>

representation is made as to whether the 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 regulatory authorities. You are urged to consult your own legal
advisors concerning the status of the Class A-1 notes as legal investments for
you. See "Legal Investment Considerations."

ERISA Considerations
      In general, the Class A-1 notes will be eligible for purchase by
retirement plans subject to the Employee Retirement Income Security Act.
Investors should consult their counsel with respect to the consequences under
the Employee Retirement Income Security Act and the Internal Revenue Code of
the plan's acquisition and ownership of the certificates.

Book-Entry Registration
      The Class A-1 notes will be initially issued in book-entry form only.
Persons acquiring beneficial ownership of interests in the Class A-1 notes will
hold their interests through the Depository Trust Company in the United States
or Cedelbank or Euroclear outside of the United States. Transfers within the
Depository Trust Company, Cedelbank or Euroclear will be in accordance with the
usual rules and operating procedures of the relevant system. Crossmarket
transfers between persons holding directly or indirectly through the Depository
Trust Company, on the one hand, and persons holding directly or indirectly
through Cedelbank or Euroclear, on the other hand, will take place in the
Depository Trust Company through the relevant depositories of Cedelbank or
Euroclear.

Collections
      The issuer trustee will receive for each collection period amounts, which
are known as collections, which include:

    .  payments of interest, principal, fees and other amounts under the
       housing loans;

    .  proceeds from the enforcement of the housing loans and mortgages and
       other securities relating to those housing loans;

    .  amounts received under mortgage insurance policies;

    .  amounts received from the seller or servicer for breaches of
       representations or undertakings; and

    .  interest on amounts in the collections account, other than certain
       excluded amounts, and income received on authorized short-term
       investments of the trust.

      Collections will be allocated between income and principal. Collections
attributable to interest, plus some other amounts, are known as the available
income amount. The collections attributable to principal, plus some other
amounts, are known as the available principal amount.

      The available income amount is used to pay fees, expenses and interest on
the notes and redraw bonds. The available principal amount is used to pay,
among other things, principal on the notes and redraw bonds. If there is an
excess of available income amount after payment of fees, expenses and interest
on the notes and redraw bonds, the excess income will be used to reimburse any
principal charge-offs on the notes, the redraw bonds and the standby redraw
facility. Any remaining excess will be distributed to the residual unitholder.

                                       18
<PAGE>

Interest on the Notes and Redraw Bonds
      Interest on the notes and redraw bonds is payable quarterly in arrears on
each distribution date. The amount available to pay interest on the notes and
redraw bonds will be paid rateably between: the currency swap provider which in
turn will pay interest on the Class A-1 notes; the Class A-2 notes; and the
redraw bonds. Interest will be paid on the Class B notes only after the
payments of interest on the Class A-1 and Class A-2 notes and the redraw bonds
are made. Interest on each class of notes and the redraw bonds is calculated
for each accrual period as follows:

    .  at the note's or redraw bond's interest rate;

    .  on the outstanding principal balance of that note or redraw bond at
       the beginning of that accrual period; and

    .  on the basis of the actual number of days in that accrual period and
       a year of 360 days for the Class A-1 notes or a year of 365 days for
       the Class A-2 notes, the Class B notes and the redraw bonds.

Principal on the Notes and Redraw Bonds
      Principal on the notes and redraw bonds will be payable on each
distribution date. The amount available to be paid in respect of principal on
the notes and redraw bonds will be paid first to redraw bondholders with
priority given to redraw bonds with earlier issue dates until the outstanding
principal balance of the redraw bonds, as reduced by losses allocated against
the redraw bonds, is reduced to zero. After payments in respect of the redraw
bonds, the available principal up to a specified maximum amount will be paid
rateably to the currency swap provider, which in turn will pay principal on the
Class A-1 notes and to the Class A-2 noteholders in respect of principal on the
Class A-2 notes until the outstanding principal balance of the Class A-1 notes
and Class A-2 notes respectively, as reduced by losses allocated against the
Class A-1 and A-2 notes, is reduced to zero. The specified maximum amount will
vary in accordance with the stepdown conditions, with the result that, in some
circumstances, and to a limited extent, the Class B notes will receive
principal rateably with the Class A notes. The balance of the available
principal will be paid to Class B noteholders in respect of principal on the
Class B notes until the outstanding principal balance of the Class B notes, as
reduced by losses allocated against the Class B notes, is reduced to zero. On
each distribution date, the outstanding principal balance of each note and
redraw bond will be reduced by the amount of the principal payment made on that
date on that note or redraw bond. The outstanding principal balance of each
note and redraw bond will also be reduced by the amount of principal losses on
the housing loans allocated to that note or redraw bond. If the security trust
deed is enforced after an event of default, the proceeds from the enforcement
will be distributed rateably among all of the Class A notes and redraw bonds
and prior to any distributions to the Class B notes.

Allocation of Cash Flows
      On each distribution date, the issuer trustee will pay interest and repay
principal to each noteholder and redraw bondholder to the extent of the
available income amount and available principal amount on that distribution
date available to be applied for these purposes. The charts on the next two
pages summarize the flow of payments.

      The Class A-1 notes are complex securities issued by a foreign entity and
secured by property located in a foreign jurisdiction. You should consider the
following risk factors in deciding whether to purchase the Class A-1 notes.

 The Class A-1 notes will be paid     .  The Class A-1 notes are debt
 only from the assets of the trust       obligations of the issuer trustee only
                                         in its capacity as trustee of the
                                         trust. The Class A-1 notes do not
                                         represent an interest in or obligation
                                         of any of the other parties to the
                                         transaction. The assets of the trust
                                         will be the sole source of payments on
                                         the Class A-1 notes. The issuer
                                         trustee's other assets will only be
                                         available to make payments on the
                                         Class A-1 notes if the issuer trustee
                                         is negligent, commits fraud or in some
                                         circumstances where the issuer trustee
                                         fails to comply with or breaches an
                                         obligation imposed upon it under the
                                         documents. Therefore, if the assets of
                                         the trust are insufficient to pay the
                                         interest and principal on your Class
                                         A-1 notes when due, there will be no
                                         other source from which to receive
                                         these payments and you may not get
                                         back your entire investment or the

                                         will not be notified of the equitable
                                         assignment. The housing loans will be

                                       the fixed rate swap, respectively, the
                                       issuer trustee will make the

                                       Thus, if the issuer trustee makes a
                                       termination payment, there may not be
                                       sufficient funds remaining to pay

                                       Thus, you will receive less interest
                                       than is scheduled to be paid on your

Commonwealth Bank
      The Commonwealth Bank of Australia was established in 1911 by an Act of
Australia's Commonwealth Parliament as a government owned enterprise to conduct
commercial and savings banking business. For a period it also operated as
Australia's central bank until this function was transferred to the Reserve
Bank of Australia in 1959. The process of privatization of the Commonwealth
Bank was commenced by Australia's Commonwealth Government in 1990 and was
completed in July 1996. The Commonwealth Bank is now a public company listed on
the Australian Stock Exchange Limited. Its registered office is at Level 1, 48
Martin Place Sydney New South Wales, Australia.

      Commonwealth Bank is one of the four major trading banks in Australia and
provides a wide range of banking, financial and related services to over 7.7
million customers with a branch network of approximately 1,400 locations
throughout Australia and internationally.

      As at June 30, 1999 Commonwealth Bank and its subsidiaries, on a
consolidated basis, had total assets of A$138.1 billion, deposits of A$93.4
billion and total regulatory capital of A$9.8 billion. Operating profit after
tax, abnormals and outside equity interests for the twelve months to June 30,
1999 was A$1.42 billion.

      Commonwealth Bank currently files periodic reports with the Securities
and Exchange Commission pursuant to the Exchange Act. For additional financial
and other information with respect to Commonwealth Bank, please refer to the
most recent Form 20-F filed with the Commission.

      The Australian banking activities of Commonwealth Bank come under the
regulatory supervision of the Australian Prudential Regulation Authority. For a
further description of the business operations of Commonwealth Bank, see "The
Servicer."

The Manager
      The manager, Securitisation Advisory Services Pty. Limited, is a wholly
owned subsidiary of Commonwealth Bank. Its principal business activity is the
management of securitization trusts established under Commonwealth Bank's
Medallion Programme and the management of other securitization programs
established by Commonwealth Bank or its customers. The manager's registered
office is Level 8, 48 Martin Place Sydney New South Wales, Australia.

                            Description of the Trust

Commonwealth Bank Securitisation Trust Programme
      Commonwealth Bank established its Medallion Trust Programme pursuant to a
master trust deed for the purpose of enabling Perpetual Trustee Company
Limited, as trustee of each trust established pursuant to the Medallion Trust
Programme, to invest in pools of assets originated or purchased from time to
time by Commonwealth Bank. The master trust deed provides for the creation of
an unlimited number of trusts. The master trust deed

                                       35
<PAGE>

establishes the general framework under which trusts may be established from
time to time. The Series 2000-1G Medallion Trust is established by the master
trust deed and the series supplement. Series 2000-1G Medallion Trust is
separate and distinct from any other trust established under the master trust
deed. The assets of the Series 2000-1G Medallion Trust are not available to
meet the liabilities of any other trust and the assets of any other trust are
not available to meet the liabilities of the Series 2000-1G Medallion Trust.

Series 2000-1G Medallion Trust
      The detailed terms of the trust are set out in the master trust deed and
the series supplement.

      The series supplement, which supplements the general framework under the
master trust deed with respect to the trust, does the following:

    .  specifies the details of the notes, other than for the Class A-1
       Notes which are contained in the Class A-1 note trust deed and the
       Class A-1 note terms and conditions annexed to the Class A-1 notes;

    .  establishes the cash flow allocation;

    .  sets out the mechanism for the acquisition from Commonwealth Bank of
       the pool of housing loans and contains various representations and
       warranties by Commonwealth Bank in relation to the housing loans;

    .  contains Commonwealth Bank's appointment as initial servicer of the
       housing loans and the various powers, discretions, rights,
       obligations and protections of Commonwealth Bank in this role;

    .  specifies a number of ancillary matters associated with the operation
       of the trust and the housing pool such as the arrangements regarding
       the operation of the collections account, the custody of the title
       documents in relation to the housing loans, the fees payable to the
       issuer trustee, the manager and the servicer, the perfection of the
       issuer trustee's title to the housing loans, the termination of the
       trust and the limitation on the issuer trustee's liability; 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 notes.

Other Trusts
      In addition to the Series 2000-1G Medallion Trust, two other trusts are
established in relation to the issue of the Class A-1 notes as follows:

    .  Class A-1 Trust. The Class A-1 note trustee acts as trustee of the
       Class A-1 trust under the Class A-1 note trust deed for the benefit
       of Class A-1 noteholders. Under the terms of the Class A-1 note trust
       deed the Class A-1 note trustee is able to enforce obligations of the
       issuer trustee for the benefit of Class A-1 noteholders and will vote
       on behalf of Class A-1 noteholders, based on their directions, at
       meetings held under the terms of the master trust deed or the
       security trust deed, including upon an event of default and
       enforcement under the security trust deed.

                                       36
<PAGE>

    .  Security Trust. The security trustee acts as trustee of the security
       trust for the benefit of noteholders, redraw bondholders and all
       other Secured Creditors under the terms of the security trust deed.
       The security trustee holds the charge over the assets of the trust
       granted by the issuer trustee under the security trust deed for the
       benefit of the Secured Creditors. If an event of default occurs under
       the security trust deed and the charge is enforced, the security
       trustee, or a receiver appointed by it, will be responsible for
       realizing the assets of the trust and the security trustee will be
       responsible for distributing the proceeds of realisation to Secured
       Creditors in the order prescribed under the security trust deed.

                     Description of the Assets of the Trust

Assets of the Trust
      The assets of the trust will include the following:

    .  the pool of housing loans, including all:

      .  principal payments paid or payable on the housing loans at any
         time from and after the cut-off date; and

      .  interest payments paid or payable on the housing loans before or
         after the cut-off date (other than the Accrued Interest Adjustment
         which is to be paid on the first distribution date to Commonwealth
         Bank as seller of the housing loans);

    .  rights under the mortgage insurance policies issued by or transferred
       to Housing Loans Insurance Corporation Pty Limited [GE Capital
       Mortgage Insurance (Australia) Pty Limited] and the Commonwealth of
       Australia and the individual property insurance policies covering the
       mortgaged properties relating to the housing loans;

    .  rights under the mortgages in relation to the housing loans;

    .  rights under collateral securities securing the housing loans;

    .  amounts on deposit in the accounts established in connection with the
       creation of the trust and the issuance of the notes, including the
       collections account, and any instruments in which these amounts are
       invested; and

    .  the issuer trustee's rights under the transaction documents.

The Housing Loans
      The housing loans are secured by registered first ranking mortgages on
properties located in Australia. The housing loans are from Commonwealth Bank's
general residential mortgage product pool and have been originated by
Commonwealth Bank in the ordinary course of its business. Each housing loan
will be one of the types of products described in "Commonwealth Bank
Residential Loan Program--Commonwealth Bank's Product Types." Each housing loan
may have some or all of the features described in the "Commonwealth Bank
Residential Loan Program--Special Features of the Housing Loans." The housing

                                       37
<PAGE>

loans are either fixed rate or variable rate loans. The mortgaged properties
consist of one-to-four family owner-occupied properties and one-to-four family
non-owner occupied properties, but do not include mobile homes which are not
permanently affixed to the ground, commercial properties or unimproved land.

Transfer and Assignment of the Housing Loans
      On the closing date, the housing loans purchased by the trust will be
specified in a sale notice from Commonwealth Bank, in its capacity as seller of
the housing loans, to the issuer trustee.

      The seller will equitably assign the housing loans, the mortgages and any
collateral securities from time to time appearing in its records as securing
those housing loans, the mortgage insurance policies and its interest in any
insurance policies on the mortgaged properties relating to those housing loans
to the issuer trustee pursuant to the sale notice. After this assignment, the
issuer trustee will be entitled to receive collections on the housing loans.

      If the issuer trustee is actually aware of the occurrence of a Perfection
of Title Event which is subsisting then, unless each rating agency confirms
that a failure to perfect the issuer trustee's title to the housing loans will
not result in a reduction, qualification or withdrawal of the credit ratings
assigned by them to the notes and redraw bonds, the issuer trustee must declare
that a Perfection of Title Event has occurred and the issuer trustee and the
manager must as soon as practicable take steps to perfect the issuer trustee's
legal title to the housing loans. These steps will include the lodgment of
transfers of the mortgages securing the housing loans with the appropriate land
titles office in each Australian State and Territory. The issuer trustee will
hold at the closing date irrevocable powers of attorney from the seller to
enable it to execute such mortgage transfers.

      Each housing loan sold to the issuer trustee is secured by an "all
moneys" mortgage, which may also secure other financial indebtedness . The
seller will also sell these other loans to the issuer trustee which will hold
these by way of a separate trust for Commonwealth Bank established under the
series supplement and known as the CBA Series 2000-1 Trust or the CBA trust.
The other loans are not assets of the Series 2000-1G Medallion Trust. The
issuer trustee will hold the proceeds of enforcement of the related mortgage,
to the extent they exceed the amount required to repay the housing loan, as
trustee for the CBA trust, in relation to that other loan. The mortgage will
secure the housing loan equitably assigned to the trust in priority to that
other loan.

      Because the seller's standard security documentation usually secures all
moneys owing by the provider of the security to the seller, it is possible that
a security held by the seller in relation to other facilities provided by it
could also secure a housing loan, even though in the seller's records the
particular security was not taken for this purpose. The seller will only assign
to the issuer trustee in its capacity as trustee of the trust those securities
that appear in its records as intended to secure the housing loans. Other
securities which by their terms technically secure a housing loan but which
were not taken for that purpose, will not be assigned for the benefit of the
noteholders or redraw bondholders.

                                       38
<PAGE>

Representations, Warranties and Eligibility Criteria
      The seller will make various representations and warranties to the issuer
trustee as of the cut-off date with respect to each housing loan being
equitably assigned by it to the issuer trustee, including that:

    .  at the time the seller entered into the related mortgage, the
       mortgage complied in all material respects with applicable laws;

    .  the seller entered into the housing loan in good faith;

    .  at the time the seller entered into the housing loan, the housing
       loan was originated in the ordinary course of the seller's business
       and since then the seller has dealt with the housing loan in
       accordance with its servicing procedures and servicing standards;

    .  at the time the seller entered into the housing loan, all necessary
       steps were taken to ensure that the related mortgage complied with
       the legal requirements applicable at that time to ensure that the
       mortgage was a first ranking mortgage, subject to any statutory
       charges, any prior charges of a body corporate, service company or
       equivalent, whether registered or not, and any other prior security
       interests which do not prevent the mortgage from being considered to
       be a first ranking mortgage in accordance with the servicing
       standards, secured over land, subject to stamping and registration in
       due course;

    .  where there is a second or other mortgage in respect of the land the
       subject of the related mortgage and the seller is not the mortgagee
       of that second or other mortgage, the seller has ensured whether by a
       priority agreement or otherwise, that the mortgage ranks ahead in
       priority to the second or other mortgage on enforcement for at least
       the principal amount plus accrued but unpaid interest of the housing
       loan and such other amount determined in accordance with the
       servicing standards;

    .  at the time the housing loan was approved, the seller had received no
       notice of the insolvency or bankruptcy of the relevant borrower or

       mortgage;

       the mortgagee, no prior ranking security interest exists in relation
       to its right, title and interest in the housing loan and related
       securities;

    .  each of the relevant mortgage documents, other than any property
       insurance policies, which is required to be stamped with stamp duty
       has been duly stamped;

    .  other than in respect of priorities granted by statute, the seller
       has not received notice from any person that it claims to have a
       security interest ranking in priority to or equal with the security
       interest held by the seller and constituted by the relevant mortgage;

       at the time of origination is insured under a mortgage insurance
       policy obtained upon origination;

    .  except in relation to fixed rate housing loans or those which can be
       converted to a fixed rate and applicable laws, binding codes and

       limitation affecting, or consent required from a borrower to effect,
       a change in the interest rate under the housing loan; and

    .  as of the cut-off date the housing loan satisfies the following
       eligibility criteria:

      .  it is secured by a mortgage over land which has erected on or
         within it a residential dwelling or unit and the terms of that
         mortgage require that dwelling or unit to be insured under a
         general home owner's insurance policy;

      .  it has a loan-to-value ratio based on the outstanding balance of
         the housing loan and the most recent valuation of the mortgaged
         property at the commencement of business on the cut-off date less
         than or equal to 95%;

      .  the amount outstanding, assuming all due payments have been made

The issuer trustee has not investigated or made any inquiries regarding the

so. The issuer trustee is entitled to rely entirely upon the representations
and warranties being correct, unless an officer of the issuer trustee involved
in the day to day administration of the trust has actual notice to the
contrary.

                                       40
<PAGE>

Breach of Representations and Warranties
      If Commonwealth Bank, the manager or the issuer trustee becomes actually
aware that a representation or warranty from Commonwealth Bank relating to any
housing loan or mortgage was incorrect when given, it must notify the others
within 5 Business Days, and provide to them sufficient details to identify the
housing loan and the reasons for believing the representation or warranty is
incorrect. None of Commonwealth Bank, the manager or the issuer trustee is
under any ongoing obligation to determine whether any representation or
warranty is incorrect when given.

      If any representation or warranty is incorrect when given and notice of
this is given not later than 5 Business Days prior to 120 days after the
closing date, and the seller does not remedy the breach to the satisfaction of
the issuer trustee within 5 Business Days of the notice being given, the
housing loan and its related securities will no longer form part of the assets
of the trust and the issuer trustee will hold them for the CBA trust. The
issuer trustee will, however, retain all collections received in connection
with that housing loan from the cut-off date to the date of delivery of the
notice. Commonwealth Bank as seller must pay to the issuer trustee the
principal amount of, and interest accrued but unpaid under the housing loan as
at the date of delivery of the relevant notice within 2 Business Days of that
housing loan ceasing to form part of the trust.

      During the 120 days after the closing date, the issuer trustee's sole
remedy for any of the representations or warranties being incorrect is the
right to the above payment from Commonwealth Bank and Commonwealth Bank has no
other liability for any loss or damage caused to the issuer trustee, any
noteholder or any other person, for any of the representations or warranties
being incorrect.

      If the breach of a representation or warranty in relation to a housing
loan is discovered after the last day for giving notices in the period 120 days
after the closing date, Commonwealth Bank must pay damages to the issuer
trustee which will be limited to principal amount outstanding and any accrued
but unpaid interest and any outstanding fees in respect of the housing loans.
The amount of the damages must be agreed between the issuer trustee and the
seller or, failing this, be determined by the seller's external auditors.

Substitution of Housing Loan Securities
      Under the series supplement, the servicer is empowered in relation to
each housing loan to, amongst other things, substitute any corresponding
mortgage, or collateral security appearing in the seller's records as intending
to secure the housing loan, as long as this is done in accordance with the
relevant mortgage insurance policy and the servicing guidelines.

Other Features of the Housing Loans
      The housing loans have the following features.

    .  Interest is calculated daily and charged in arrears.

    .  Payments can be on a monthly, bi-weekly or weekly basis. Payments are
       made by borrowers using a number of different methods, including cash
       payments at branches, checks and in most cases automatic transfer.

Details of the Housing Loan Pool
      The information in the following tables sets forth in tabular format
various details relating to the housing loans proposed to be sold to the trust
on the closing date. The information is provided as of the close of business on
[        ], 2000. All amounts have been rounded to the nearest Australian
dollar. The sum in any column may not equal the total indicated due to
rounding.

      Note that these details may not reflect the housing loan pool as of the
closing date because the seller may add additional eligible housing loans or
remove housing loans. The seller may do this if, for example, the loans
originally selected are repaid early.

      The seller will not add or remove any housing loans prior to the closing
date if this would result in a change of more than 5% in any of the
characteristics of the pool of housing loans described in this prospectus,
unless a revised prospectus is delivered to prospective investors.

                   Commonwealth Bank Residential Loan Program

Origination Process
      The housing loans to be assigned to the trust comprise a portfolio of
variable and fixed rate loans which were originated by Commonwealth Bank
through loan applications from new and existing customers. Housing loan
applications are sourced from Commonwealth Bank's branch network, its mobile
sales force, its telephone sales operation and through the internet from
Commonwealth Bank's website at "www.commbank.com.au."

Approval and Underwriting Process
      When a housing loan application is received it is processed in accordance
with Commonwealth Bank's approval policies. These policies are monitored and
are subject to continuous review by Commonwealth Bank. Commonwealth Bank, like
other lenders in the Australian residential housing loan market, does not
divide its borrowers into groups of differing credit quality for the purposes
of setting standard interest rates for its residential housing loans. In
limited situations discounted interest rates are provided to retain existing
borrowers or to attract certain high income individuals. All borrowers must
satisfy Commonwealth Bank's approval criteria described in this section.

      The approval process includes verifying the borrower's application
details, assessing their ability to repay the housing loan and determining the
valuation of the mortgaged property.

Verification of application details
      The verification process involves borrowers providing proof of identity,
evidence of income and evidence of a savings pattern. For an employed
applicant, it includes confirming employment and income levels by way of recent
payslips or tax assessments. For a self-employed or business applicant it
includes checking annual accounts and tax assessments. Statements or records of
savings are reviewed to identify any recent additional borrowings or gifts.
Where applicants are refinancing debts from another financial institution, a
check of the last six months' statements of the existing loan is made to
determine the regularity of debt payments. The credit history of any existing
borrowings from Commonwealth Bank is also checked.

Assessing ability to repay
      Based upon the application, once verified, an assessment is made of the
applicant's ability to repay the housing loan. This is primarily based on the
applicant's debt servicing to income commitment ratio along with any risk
factors identified in verifying the applicant's income, savings or credit
history. The credit decision is made using one the following processes.

    .   Credit scorecard. A credit scorecard system automatically and
        consistently applies Commonwealth Bank's credit assessment rules
        without relying on the credit experience of the inputting officer.
        The credit scorecard returns a decision to approve, reject or refer
        an application. An application is referred by the system

                                       50
<PAGE>

       if certain risk factors, such as loan size or a high commitment
       level, are present which require the application to be assessed by an
       experienced loan officer. The credit score determined by this system
       is based on historical performance data of Commonwealth Bank's
       housing loan portfolio.

    .   Credit approval authorities. Housing loan applications which are not
        credit scored and those which are referred by the credit scorecard
        are assessed by a loan officer. Each loan officer is allocated a
        credit approval authority based on their level of experience and
        past performance. Loans which have certain risk characteristics,
        such as loan size or a high commitment level, are assessed by more
        experienced loan officers. Commonwealth Bank monitors the quality of
        lending decisions and conducts regular audits of approvals.

Borrowers in respect of housing loans may be natural persons, corporations or
trusts. Housing loans to corporations and trusts may be secured, if deemed
necessary, by guarantees from directors. Guarantees may also be obtained in
other circumstances.

Valuation of mortgaged property
      For applications which successfully pass the credit decision process,
the maximum allowable loan-to-value ratio, being the ratio of the housing loan
amount to the value of the mortgaged property, is calculated and an offer for
finance is made conditional upon a satisfactory valuation of the mortgaged
property and any other outstanding conditions being satisfied. The amount of
the housing loan that will be approved for a successful applicant is based on
an assessment of the applicant's ability to service the proposed housing loan
and the loan-to-value ratio. For the purposes of calculating the loan-to-value
ratio, the value of a mortgaged property in relation to housing loans to be
assigned to the trust has been determined at origination by one of the
following methods.

    .   Valuation by valuer. Valuations by qualified professional valuers
        are carried out when there is some attribute of the housing loan or
        its mortgaged property which, in accordance with the Commonwealth
        Bank's policies, requires a professional valuer to undertake the
        assessment. These attributes include:

      .   mortgaged properties with a value in excess of A$1 million;

      .   properties in areas which are subject to landslip, subsidence or
          flooding;

      .   housing loans which are refinancing loans from another financial
          institution; and

      .   housing loans where mortgage insurance is required upon
          origination, unless otherwise approved by the mortgage insurer.

    .   Valuation on contract price or rates notice. If not valued by a
        valuer and for housing loan amounts of less than or equal to
        A$200,000 or, for mortgaged properties in the Sydney, Melbourne or
        Brisbane metropolitan areas, A$300,000, the value of the mortgaged
        property is based on the purchase price under a contract for the
        purchase by the borrower of the mortgaged property or on the

                                      51
<PAGE>

       value specified in a local government rates notice (that is,
       generally, the unimproved value of the land assessed by a government
       valuer) for the mortgaged property.

    .   Valuation by bank officer. In all other cases, the value of the
        mortgaged property is assessed by an officer of the Commonwealth
        Bank who visits the mortgaged property and compares it with recent
        sales of similar properties in the same area.

      The maximum loan-to-value ratio that is permitted for any loan is
determined according to Commonwealth Bank's credit policy and is dependent on
the size of the proposed loan, the nature and location of the proposed
mortgaged property and other relevant factors. Where more than one mortgaged
property is offered as security for a housing loan, the sum of the valuations
for each mortgaged property is assessed against the housing loan amount sought.

      Once Commonwealth Bank's formal loan offer has been accepted by the
applicant, one of Commonwealth Bank's five loan processing centres prepares the
loan security documentation and dispatches it to the borrower for execution.
After execution, the documentation, together with signed acknowledgment that
all non-documentary conditions of approval have been met, is returned by the
business unit to the loan processing centre authorizing settlement and funding
of the housing loan to proceed. In certain circumstances, settlement and
funding are completed at the business unit level.

      One of the conditions of settlement is that the borrower establish and
maintain full replacement general home owner's insurance on the mortgaged
property. Some of the housing loans have home owner's insurance provided by
Commonwealth Insurance Limited, a subsidiary of Commonwealth Bank. However,
there is no ongoing monitoring of the level of home owner's insurance
maintained by borrowers.

Commonwealth Bank's Product Types

Complete Home Loan
      This type of loan is Commonwealth Bank's traditional standard mortgage
product which consists of standard variable rate and fixed rate options. The
standard variable rate set under the Complete Home Loan product is not linked
to any other variable rates in the market. However, it may fluctuate with
market conditions. Borrowers may switch to a fixed interest rate at any time
upon payment of a switching fee as described below in "Switching Interest
Rates." Some of the housing loans will be subject to fixed rates for differing
periods.

      In addition, some Complete Home Loans have an interest rate which is
discounted by a fixed percentage to the standard variable rate or fixed rate.
These discounts are offered to members of certain professional groups and to
other high income individuals.


                                       52
<PAGE>

Economiser Home Loan
      This type of loan has a variable interest rate which is not linked to the
standard variable rate for the Complete Home Loan and which may fluctuate
independently of this and other standard variable rates in the market. The
Economiser Home Loan was introduced by Commonwealth Bank to allow borrowers who
did not require a full range of product features to reduce their interest rate.
The interest rate for the Economiser Home Loan historically has been less than
that for the Complete Home Loan. Of the features described below, at present
only those headed "Redraw and Further Advances," "Payment Holiday" and "Early
Repayment" are available for Economiser Home Loans. To take advantage of other
features borrowers with Economiser Home Loans must, with the agreement of
Commonwealth Bank and upon payment of a fee, switch their housing loan to the
Complete Home Loan product. However, these or other features may in the future
be offered to borrowers with Economiser Home Loans.

Special Features of the Housing Loans
      Each housing loan may have some or all of the features described in this
section. In addition, during the term of any housing loan, Commonwealth Bank
may agree to change any of the terms of that housing loan from time to time at
the request of the borrower.

Switching Interest Rates
      Borrowers may elect for a fixed rate, as determined by Commonwealth Bank,
to apply to their housing loan for a period of up to 10 years. These housing
loans convert to the standard variable interest rate at the end of the agreed
fixed rate period unless the borrower elects to fix the interest rate for a
further period.

      Any variable rate converting to a fixed rate product will automatically
be matched by an increase in the fixed rate swap to hedge the fixed rate
exposure.

Substitution of Security
      A borrower may apply to the servicer to achieve the following:

    .   substitute a different mortgaged property in place of the existing
        mortgaged property securing a housing loan; or

    .   release a mortgaged property from a mortgage.

      If the servicer's credit criteria are satisfied and another property is
substituted for the existing security for the housing loan, the mortgage which
secures the existing housing loan may be discharged without the borrower being
required to repay the housing loan. The servicer must obtain the consent of any
relevant mortgage insurer to the substitution of security or a release of a
mortgage where this is required by the terms of a mortgage insurance policy.

Redraws and Further Advances
      Each of the variable rate housing loans allows the borrower to redraw
principal repayments made in excess of scheduled principal repayments during
the period in which the

                                       53
<PAGE>

relevant housing loan is charged a variable rate of interest. Redraws must be
for at least A$2,000 per transaction. Borrowers may request a redraw at any
time subject to meeting certain credit criteria at that time. The borrower may
be required to pay a fee to Commonwealth Bank in connection with a redraw.
Currently, Commonwealth Bank does not permit redraws on fixed rate housing
loans. A redraw will not result in the related housing loan being removed from
the trust.

      In addition, Commonwealth Bank may agree to make a further advance to a
borrower under the terms of a housing loan. Where a further advance does not
result in the previous scheduled principal balance of the housing loan being
exceeded by more than one scheduled monthly instalment, the further advance
will not result in the housing loan being removed from the trust. Where a
further advance does result in the previous scheduled principal balance of the
housing loan being exceeded by more than one scheduled monthly instalment,
Commonwealth Bank must pay to the trust the principal balance of the housing
loan and accrued and unpaid interest and fees on the housing loan. If this
occurs the housing loan will be treated as being repaid and will cease to be an
asset of the trust.

      A further advance to a borrower may also be made under the terms of
another loan or as a new loan. These loans may share the same security as a
housing loan assigned to the trust but will be subordinated upon the
enforcement of that security to the housing loan.

Payment Holiday
      A borrower is allowed a payment holiday where the borrower has prepaid
principal, creating a difference between the outstanding principal balance of
the loan and the scheduled amortized principal balance of the housing loan. The
borrower is not required to make any payments, including payments of interest,
until the outstanding principal balance of the housing loan plus unpaid
interest equals the scheduled amortized principal balance. The failure by the
borrower to make payments during a payment holiday will not cause the related
housing loan to be considered delinquent.

Early Repayment
      A borrower will not incur break fees if an early repayment or partial
prepayment of principal occurs under a variable rate housing loan contract.

      A borrower may incur break fees or receive break benefits if an early
repayment or partial prepayment of principal occurs on a fixed rate housing
loan. However, [many] fixed rate loans allow for early repayment by the
borrower of up to A$5,000 in any 12 month period without any break fees being
applicable. Break benefits will be paid to the borrower.

Combination or "Split" Housing Loans
      A borrower may elect to split a housing loan into separate funding
portions which may, among other things, be subject to different types of
interest rates. Each part of the housing loan is effectively a separate loan
contract, even though all the separate loans are secured by the same mortgage.

                                       54
<PAGE>

Interest Offset
      Commonwealth Bank offers borrowers an interest offset product known as a
mortgage interest saver account under which the interest accrued on the
borrower's deposit account is offset against interest on the borrower's housing
loan. Commonwealth Bank does not actually pay interest to the borrower on the
loan offset account, but reduces the amount of interest which is payable by the
borrower under its housing loan. The borrower continues to make its scheduled
mortgage payment with the result that the portion allocated to principal is
increased by the amount of interest offset. Commonwealth Bank will pay to the
trust the aggregate of all interest amounts offset. These amounts will
constitute Finance Charge Collections for the relevant period. The mortgage
interest saver account must be in the same name as the housing loan.

      If, following a Perfection of Title Event, the trust obtains legal title
to a housing loan, Commonwealth Bank will no longer be able to offer an
interest offset arrangement for that housing loan.

Interest Only Periods
      A borrower may also request to make payments of interest only on his or
her housing loan for a period of up to 5 years. If Commonwealth Bank agrees to
such a request it does so conditional upon higher principal repayments applying
upon expiry of the interest only period so that the housing loan is repaid
within its original term.

Additional Features
      Commonwealth Bank may from time to time offer additional features in
relation to a housing loan which are not described in the preceding section or
may cease to offer features that have been previously offered and may add,
remove or vary any fees or other conditions applicable to such features.

                        The Mortgage Insurance Policies

General
      The mortgage insurance policies consist of:

    .  high LTV mortgage insurance policies in relation to individual
       housing loans which had a loan-to-value ratio of greater than 80% at
       the time that they were originated; and

    .  a master mortgage insurance policy to provide mortgage insurance in
       relation to the balance of the housing loans.

The High LTV Mortgage Insurance Policies
      High LTV mortgage insurance policies entered into before December 12,
1997 represent liabilities of the Commonwealth of Australia and are presently
managed on behalf of the Commonwealth of Australia by Housing Loans Insurance
Corporation Pty Ltd. High LTV mortgage insurance policies entered into on or
after December 12, 1997 represent liabilities of Housing Loans Insurance
Corporation Pty Ltd only. References in this section to

                                       55
<PAGE>

the mortgage insurer in relation to the high LTV mortgage insurance policies
entered into before December 12, 1997 are to Housing Loans Insurance
Corporation Pty Ltd acting on behalf of the Commonwealth of Australia.

      The high LTV mortgage insurance policies insure the issuer trustee
against losses in respect of housing loans which had a loan-to-value ratio of
greater than 80% at the time of origination. They were required to be taken out
at the commencement of the housing loan and will be equitably assigned by the
seller to the issuer trustee on the closing date. Each borrower paid a single
upfront premium for their respective high LTV mortgage insurance policy and no
further premium is payable by the seller or the issuer trustee.

Period of Cover
      The issuer trustee has the benefit of the high LTV mortgage insurance
policies from the closing date until the policy is canceled by the mortgage
insurer. An individual high LTV mortgage insurance policy may be canceled by
the mortgage insurer in the following circumstances:

    .  the issuer trustee, without the approval of the mortgage insurer:

      .  approves any transfer or assignment of the mortgaged property
         without a full discharge of the corresponding mortgage and all
         moneys secured by that mortgage; or

      .  takes possession of the mortgaged property, sells it, takes
         foreclosure action or appoints any receiver or manager over it;

      .  where the insured is not a lender approved by the mortgage
         insurer, if at any time there is not a servicer approved by the
         mortgage insurer; or

      .  where the mortgage is not a first mortgage, if the issuer trustee
         refuses or fails to take action required by the mortgage insurer
         to oppose any application by a prior mortgagee for foreclosure
         against the mortgagor and the issuer trustee.

Cover for Losses
      Under each high LTV mortgage insurance policy, the mortgage insurer
insures the issuer trustee against loss if a default occurs in relation to the
insured housing loan and if one of the events entitling a claim to be made
occurs.

      No claim can be made for a loss unless:

    .  the issuer trustee has sold the mortgaged property;

    .  the issuer trustee has become the absolute owner of the mortgaged
       property by foreclosure;

    .  the relevant mortgagor has sold the mortgaged property with the
       express consent of the issuer trustee given with the prior written
       approval of the mortgage insurer;


                                       56
<PAGE>

    .  the mortgaged property has been compulsorily acquired or sold by any
       government, semi-governmental or local government authority for
       public purposes;

    .  where the mortgage is not a first mortgage, a prior mortgagee has
       sold or become absolute owner of the mortgaged property by
       foreclosure; or

    .  the mortgage insurer has agreed to pay a claim.

      The loss in respect of a housing loan insured under a high LTV mortgage
insurance policy is calculated by:

    .  adding together:

      .  the outstanding principal of the housing loan, after taking into
         account all amounts received by the issuer trustee as compensation
         for the compulsory acquisition of the mortgaged property or any
         rents, profits or proceeds from the mortgaged property and all
         amounts received by the issuer trustee under any insurance policy
         in relation to loss arising from destruction of or damage to the
         mortgaged property and not applied in restoration or repair at the
         earliest of:

             .  the date of completion of the sale or compulsory acquisition
                of the mortgaged property;

             .  the date upon which the issuer trustee became the absolute
                owner of the mortgaged property by foreclosure;

             .  the date upon which a claim is paid by the mortgage insurer;
                and

             .  where the relevant mortgage is not a first mortgage and where
                a prior mortgagee has sold the mortgaged property or has taken
                foreclosure action, the date on which the issuer trustee
                receives from the prior mortgagee so much of the proceeds of
                that sale as are payable to the issuer trustee, or where no
                part of these proceeds is so payable, the date on which the
                issuer trustee becomes aware of completion of the sale or that
                the prior mortgagee has become the absolute owner of the
                mortgaged property;

      .  interest paid in respect of the housing loan up to and including
         the earliest of the dates referred to in the previous 4 bullet
         points at the non-default rate specified in the housing loan;

      .  amounts recoverable by the issuer trustee under the terms of the
         mortgage in respect of:

             .  amounts properly paid or incurred by the issuer trustee in
                respect of the mortgaged property for premiums on general
                insurance policies, levies and other charges payable to a body
                corporate under the Australian strata title system, rates,
                taxes and other statutory charges up to a limit in respect of
                land tax as specified by the mortgage insurer;

                                       57
<PAGE>

             .  reasonable and necessary legal and other fees and
                disbursements paid or incurred by the issuer trustee in
                enforcing or protecting its rights under the mortgage;

             .  amounts not exceeding A$1,000 paid or incurred by the issuer
                trustee for repair, maintenance and protection of the
                mortgaged property or such greater amounts incurred with the
                prior approval of the mortgage insurer; and

             .  costs related to the sale of the mortgaged property by the
                issuer trustee;

      .  to the extent not otherwise included above, and the mortgage
         insurer determines that they should be included, unpaid fines,
         penalties, additional interest and other similar amounts which are
         properly incurred by the issuer trustee under the mortgage or in
         respect of the housing loan; and

    .  subtracting from the above the aggregate of:

      .  all amounts received by the issuer trustee under any related
         collateral security;

      .  where the issuer trustee has sold the mortgaged property, the sale
         price less any amount required to discharge any prior mortgage;

      .  where the issuer trustee or a prior mortgagee has taken
         foreclosure action, the value of the issuer trustee's interest in
         the mortgaged property as agreed between the mortgage insurer and
         the issuer trustee; and

      .  any amount by which a claim may be reduced.

Reduction of Claims
      There are a number of restrictions imposed on the insured under each
mortgage insurance policy which may entitle the mortgage insurer to refuse or
reduce the amount of a claim with respect to a housing loan, including:

    .  the failure of the servicer to be approved by the mortgage insurer;

    .  the failure of the housing loan contract to require that the related
       mortgaged property be insured under a general insurance policy;

    .  the existence of an encumbrance or other interest which affects or
       has priority over the related mortgage;

    .  the housing loan or related mortgage being materially altered or
       modified without the mortgage insurer's consent; and

    .  the occurrence of other circumstances reducing the insured's rights
       under any insured housing loan or related mortgage.

The Master Mortgage Insurance Policy

Cover
      The master mortgage insurance policy is provided by [Housing Loans
Insurance Corporation Pty Ltd]. The master mortgage insurance policy insures
the issuer trustee against losses in respect of housing loans which had a loan-
to-value ratio of less than or equal to 80% at the time of origination. The
seller will prior to the closing date pay a single upfront premium for the
master mortgage insurance policy. No further premium is payable by the seller
or the issuer trustee.

Period of Cover
      The issuer trustee has the benefit of the master mortgage insurance
policy in respect of each housing loan insured under it from the closing date
until the earliest of:

    .  the date the housing loan or the mortgage securing the housing loan
       is assigned, transferred or mortgaged to another party without the
       mortgage insurer's consent;

    .  the date the housing loan is repaid in full;

    .  the date the housing loan ceases to be secured by the relevant
       mortgage other than where the mortgage is discharged by the operation
       of a compulsory acquisition or sale by a government for public
       purpose;

    .  the date the master mortgage insurance policy is canceled in respect
       of the housing loan in accordance with the terms of the master
       mortgage insurance policy; and

    .  the maturity date set out in the certificate of insurance issued by
       the mortgage insurer in relation to the housing loan or as extended
       with the consent of the mortgage insurer or as varied by a court
       under the Australian Consumer Credit Code.

Cover for Losses
      If a loss date occurs in respect of a housing loan insured under the
master mortgage insurance policy, the mortgage insurer will pay to the issuer
trustee the loss in respect of a housing loan.

      A loss date means:

    .  if a default occurs under the insured loan and the mortgaged property
       is sold pursuant to enforcement proceedings, the date on which the
       sale is completed;

    .  if a default occurs under the insured loan and the issuer trustee or
       a prior approved mortgagee becomes the absolute owner by foreclosure
       of the mortgaged property, the date on which this occurs;

    .  if a default occurs under the insured loan and the mortgagor sells
       the mortgaged property with the prior approval of the issuer trustee
       and the mortgage insurer, the date on which the sale occurs;


                                       59
<PAGE>

    .  if the mortgaged property is compulsorily acquired or sold by a
       government for public purposes and there is a default under the
       housing loan, or, where the mortgage has been discharged by the
       operation of the compulsory acquisition or sale and there is a
       failure in repayment of the housing loan which would have been a
       default but for the occurrence of that event, the later of the date
       of the completion of the acquisition or sale or 28 days after the
       date of the default; or

    .  where the mortgage insurer has agreed to pay a claim under the master
       mortgage insurance policy, the date specified in that agreement.

      A "default" in respect of an insured housing loan means any event which
triggers the issuer trustee's power of sale in relation to the mortgaged
property.

      The loss payable by the mortgage insurer to the issuer trustee in
respect of an insured loan is the amount outstanding, less the deductions
referred to below, in relation to the housing loan, in each case calculated as
at the loss date.

      The amount outstanding under a housing loan is the aggregate of the
following:

    .  the principal amount outstanding together with any interest, fees or
       charges outstanding as at the loss date;

    .  fees and charges paid or incurred by the issuer trustee; and

    .  other amounts, including fines or penalties, approved by the mortgage
       insurer, which the issuer trustee is entitled to recover under the
       housing loan or a related guarantee.

      The mortgage insurer may make the following deductions:

    .  where the mortgaged property is sold, the sale price or where the
       mortgaged property is compulsorily acquired, the amount of
       compensation, less, in either case, any amount required to discharge
       any approved prior mortgage;

    .  where foreclosure action occurs, the value of the issuer trustee's
       interest in the mortgaged property, including the interest of any
       unapproved prior mortgagee;

    .  any amount received by the issuer trustee under any collateral
       security;

    .  any amounts paid to the issuer trustee by way of rents, profits or
       proceeds in relation to the mortgaged property or under any insurance
       policy not applied in restoration or repair;

    .  any interest that exceeds interest at the non-default interest rate
       payable in relation to the housing loan;

    .  any fees or charges other than:

      .  premiums for general insurance policies, levies and other charges
         payable to a body corporate under the Australian strata titles
         system, rates, taxes and other statutory charges;


                                      60
<PAGE>

      .  reasonable and necessary legal and other fees and disbursements of
         enforcing or protecting the issuer trustee's rights under the
         housing loan, up to a maximum of A$2,000, unless otherwise
         approved in writing by the mortgage insurer;

      .  repair, maintenance and protection of the mortgaged property, up
         to a maximum amount of A$1,000, unless otherwise approved in
         writing by the mortgage insurer; and

      .  reasonable costs of the sale of the mortgaged property up to a
         maximum amount of A$1,000 plus selling agent's commission, unless
         otherwise approved in writing by the mortgage insurer, in
         addition, if any fees and charges exceed those recoverable under
         the Australian Consumer Credit Code less any amount that must be
         accounted for to the borrower or the relevant mortgagor they will
         be excluded;

    .  losses arising out of damage to the mortgaged property other than:

      .  fair wear and tear; or

      .  losses recovered and applied in the restoration or repair of the
         mortgaged property or losses recovered under a general insurance
         policy and applied to reduce the amount outstanding under the
         housing loan; and

    .  any amounts by which a claim may be reduced under the master mortgage
       insurance policy.

Refusal or Reduction in Claim
      The mortgage insurer may refuse or reduce the amount of a claim with
respect to a housing loan in certain circumstances, including:

    .  the mortgaged property is not insured under a general home owner's
       insurance policy;

    .  there is not a servicer approved by the mortgage insurer;

    .  the housing loan has not been duly registered with the Land Titles
       Office in the relevant Australian jurisdiction;

    .  the issuer trustee does not comply with the obligation to seek the
       mortgage insurer's consent under certain circumstances;

    .  the issuer trustee does not comply with certain reporting
       obligations; or

    [. any item used or relied upon by the issuer trustee is not year 2000
       ready as specified in the master mortgage insurance policy.]

The mortgage insurer may also reduce its liability or cancel the master
mortgage insurance policy, in relation to a particular housing loan if the
issuer trustee has failed to comply with its reporting obligations.


                                       61
<PAGE>

Exclusions
      The master mortgage insurance policy does not cover any loss arising
from:

    .  any war or warlike activities;

    .  the use, existence or escape of nuclear weapons or nuclear
       contamination;

    .  the existence or escape of any pollution or environmentally hazardous
       material;

    .  the fact that the housing loan or any collateral security is void or
       unenforceable;

    .  any failure of the housing loan or collateral security to comply with
       the requirements of the Australian Consumer Credit Code; or

    [. the failure of the issuer trustee's computer systems to be year 2000
       ready as specified in the master mortgage insurance policy.]

Description of the Mortgage Insurers

                       Description of the Class A-1 Notes

General
      The issuer trustee will issue the Class A-1 notes on the closing date
pursuant to a direction from the manager to the issuer trustee to issue the
Class A-1 notes and the terms of the master trust deed, the series supplement,
the Class A-1 note trust deed and the underwriting agreement. The Class A-1
notes will be governed by the laws of New South Wales. The following summary
describes the material terms of the Class A-1 notes. The summary does not
purport to be complete and is subject to the terms and conditions of the Class
A-1 notes, which are attached as an appendix to this prospectus, and to the
terms and conditions of the Class A-1 note trust deed and the other transaction
documents. The Class A-1 noteholders are bound by, and deemed to have notice
of, all the provisions of the transaction documents.

Form of the Class A-1 Notes

Book-Entry Registration
      The Class A-1 notes will be issued only in permanent book-entry format in
minimum denominations of US$100,000. While the notes are in book-entry format,
all references to actions by the Class A-1 noteholders will refer to actions
taken by the Depository Trust Company, DTC, upon instructions from its
participating organizations and all references in this prospectus to
distributions, notices, reports and statements to Class A-1 noteholders will
refer to distributions, notices, reports and statements to DTC or its nominee,
as the registered noteholder, for distribution to owners of the Class A-1 notes
in accordance with DTC's procedures.

      Class A-1 noteholders may hold their interests in the Class A-1 notes
through DTC, in the United States, or Cedelbank or the Euroclear System, in
Europe, if they are participants in those systems, or indirectly through
organizations that are participants in those systems. Cede & Co., as nominee
for DTC, will hold the Class A-1 notes. Cedelbank and Euroclear will hold
omnibus positions on behalf of their respective participants, through
customers' securities accounts in Cedel's and Euroclear's names on the books of
their respective depositaries. The depositaries in turn will hold the positions
in customers' securities accounts in the depositaries' names on the books of
DTC.

      DTC has advised the manager and the underwriters that it is:

    .  a limited-purpose trust company organized under the New York Banking
       Law;

    .  a "banking organization" within the meaning of the New York Banking
       Law;

    .  a member of the Federal Reserve System;

    .  a "clearing corporation" within the meaning of the New York Uniform
       Commercial Code; and

    .  a "clearing agency" registered under the provisions of Section 17A of
       the Exchange Act.


                                       63

      DTC holds securities for its participants and facilitates the clearance
and settlement among its participants of securities transactions, including
transfers and pledges, in deposited securities through electronic book-entry
changes in its participants' accounts. This eliminates the need for physical
movement of securities. DTC participants include securities brokers and
dealers, banks, trust companies, clearing corporations and other organizations.
Indirect access to the DTC system is also available to others including
securities brokers and dealers, banks, and trust companies that clear through
or maintain a custodial relationship with a participant, either directly or
indirectly. The rules applicable to DTC and its participants are on file with
the SEC.

      Transfers between participants on the DTC system will occur in accordance
with DTC rules. Transfers between participants on the Cedelbank system and
participants on the Euroclear system will occur in accordance with their rules
and operating procedures.

      Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through Cedelbank
participants or Euroclear participants, on the other, will be effected by DTC
in accordance with DTC rules on behalf of the relevant European international
clearing system by that system's depositary. However, these cross-market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in that 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 its
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. Cedelbank participants and Euroclear participants may not deliver
instructions directly to their system's depositary.

      Because of time-zone differences, credits of securities in Cedelbank or
Euroclear as a result of a transaction with a DTC participant will be made
during the subsequent securities settlement processing, dated the business day
following the DTC settlement date. The credits for any transactions in these
securities settled during this processing will be reported to the relevant
Cedelbank participant or Euroclear participant on that business day. Cash
received in Cedelbank or Euroclear as a result of sales of securities by or
through a Cedelbank participant or a Euroclear participant to a DTC participant
will be received and available on the DTC settlement date.

      However, it will not be available in the relevant Cedelbank or Euroclear
cash account until the business day following settlement in DTC.

      Purchases of Class A-1 notes held through the DTC system must be made by
or through DTC participants, which will receive a credit for the Class A-1
notes on DTC's records. The ownership interest of each actual Class A-1
noteholder is in turn to be recorded on the DTC participants' and indirect
participants' records. Class A-1 noteholders will not receive written
confirmation from DTC of their purchase. However, Class A-1 noteholders are
expected to receive written confirmations providing details of the transaction,
as well as

                                       64
<PAGE>

periodic statements of their holdings, from the DTC participant or indirect
participant through which the Class A-1 noteholder entered into the
transaction. Transfers of ownership interests in the Class A-1 notes are to be
accomplished by entries made on the books of DTC participants acting on behalf
of the Class A-1 noteholders. Class A-1 noteholders will not receive notes
representing their ownership interest in offered Class A-1 notes unless use of
the book-entry system for the Class A-1 notes is discontinued.

      To facilitate subsequent transfers, all securities deposited by DTC
participants with DTC are registered in the name of DTC's nominee, Cede & Co.
The deposit of securities with DTC and their registration in the name of Cede &
Co. effects no change in beneficial ownership. DTC has no knowledge of the
actual Class A-1 noteholders of the Class A-1 notes; DTC's records reflect only
the identity of the DTC participants to whose accounts the Class A-1 notes are
credited, which may or may not be the actual beneficial owners of the Class A-1
notes. The DTC participants will remain responsible for keeping account of
their holdings on behalf of their customers.

      Conveyance of notices and other communications by DTC to DTC
participants, by DTC participants to indirect participants, and by DTC
participants and indirect participants to Class A-1 noteholders will be
governed by arrangements among them and by any statutory or regulatory
requirements as may be in effect from time to time.

      Neither DTC nor Cede & Co. will consent or vote on behalf of the notes.
Under its usual procedures, DTC mails an omnibus proxy to the issuer trustee or
the security trustee as soon as possible after the record date, which assigns
Cede & Co.'s consenting or voting rights to those DTC participants to whose
accounts the Class A-1 notes are credited on the record date, identified in a
listing attached to the proxy.

      Principal and interest payments on the Class A-1 notes will be made to
DTC. DTC's practice is to credit its participants' accounts on the applicable
distribution date in accordance with their respective holdings shown on DTC's
records unless DTC has reason to believe that it will not receive payment on
that distribution date. Standing instructions, customary practices, and any
statutory or regulatory requirements as may be in effect from time to time will
govern payments by DTC participants to Class A-1 noteholders. These payments
will be the responsibility of the DTC participant and not of DTC, the issuer
trustee, the Class A-1 note trustee or the principal paying agent. Payment of
principal and interest to DTC is the responsibility of the issuer trustee,
disbursement of the payments to DTC participants is the responsibility of DTC,
and disbursement of the payments to Class A-1 noteholders is the responsibility
of DTC participants and indirect participants.

      DTC may discontinue providing its services as securities depository for
the Class A-1 notes at any time by giving reasonable notice to the principal
paying agent. Under these circumstances, if a successor securities depository
is not obtained, definitive notes are required to be printed and delivered.

      According to DTC, the foregoing information about DTC has been provided
for informational purposes only and is not intended to serve as a
representation, warranty or contract modification of any kind.

      Cedelbank is incorporated under the laws of Luxembourg as a professional
depository. Cedelbank holds securities for its participating organizations and
facilitates the clearance and settlement of securities transactions between
Cedelbank participants through electronic book-entry changes in accounts of
Cedelbank participants, thereby eliminating the need for physical movement of
notes. Transactions may be settled in Cedelbank in any of 32 currencies,
including U.S. dollars.

      Cedelbank participants are financial institutions around the world,
including underwriters, securities brokers and dealers, banks, trust companies,
and clearing corporations. Indirect access to Cedelbank is also available to
others, including banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Cedelbank participant,
either directly or indirectly.

      The Euroclear System was created in 1968 to hold securities for its
participants and to clear and settle transactions between Euroclear
participants through simultaneous electronic book-entry delivery against
payment. This eliminates the need for physical movement of notes. Transactions
may be settled in any of 32 currencies, including U.S. dollars.

      The Euroclear System is operated by Morgan Guaranty Trust Company of New
York, Brussels, Belgium office, the Euroclear operator, under contract with
Euroclear Clearance System, Societe Cooperative, a Belgium cooperative
corporation, the Euroclear 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
Euroclear cooperative. The board of the Euroclear cooperative establishes
policy for the Euroclear System.

      Euroclear participants include banks, including central banks, securities
brokers and dealers and other professional financial intermediaries. Indirect
access to the Euroclear System is also available to other firms that maintain a
custodial relationship with a Euroclear participant, either directly or
indirectly.

      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. These terms and
conditions govern transfers of securities and cash within the Euroclear System,
withdrawal of securities and cash from the Euroclear System, and receipts of
payments for securities in the Euroclear System. All securities in the
Euroclear System are held on a fungible basis without attribution of specific
notes to specific securities clearance accounts. The Euroclear operator acts
under these terms and conditions only on behalf of Euroclear participants and
has no record of or relationship with persons holding through Euroclear
participants.


                                       66
<PAGE>

      Distributions on the Class A-1 notes held through Cedelbank or Euroclear
will be credited to the cash accounts of Cedelbank participants or Euroclear
participants in accordance with the relevant system's rules and procedures, to
the extent received by its depositary. These distributions must be reported for
tax purposes in accordance with United States tax laws and regulations.
Cedelbank or the Euroclear operator, as the case may be, will take any other
action permitted to be taken by a Class A-1 noteholder on behalf of a Cedelbank
participant or Euroclear participant only in accordance with its rules and
procedures, and depending on its depositary's ability to effect these actions
on its behalf through DTC.

      Although DTC, Cedelbank and Euroclear have agreed to the foregoing
procedures in order to facilitate transfers of interests in Class A-1 notes
among participants of DTC, Cedelbank and Euroclear, they are under no
obligation to perform or continue to perform these procedures and these
procedures may be discontinued at any time.

Definitive Notes
      Class A-1 notes issued in definitive form are referred to in this
prospectus as "definitive notes." Class A-1 notes will be issued as definitive
notes, rather than in book entry form to DTC or its nominee, only if one of the
following events occurs:

    .  the issuer trustee, at the direction of the manager, advises the
       Class A-1 note trustee in writing that DTC or any replacement
       clearing agency is no longer willing or able to discharge properly
       its responsibilities as depository for the Class A-1 notes, and the
       manager is not able to locate a qualified successor;

    .  the issuer trustee, at the direction of the manager, at the manager's
       option, advises the Class A-1 note trustee in writing that it elects
       to terminate the book-entry system through DTC or any replacement
       clearing agency; or

    .  after the commencement of enforcement of the charge under the
       security trust deed, the beneficial owners of Class A-1 notes with a
       Stated Amount of greater than 50% of the aggregate Stated Amount of
       all the Class A-1 notes, advise the issuer trustee, through DTC or
       any replacement clearing agency, that the continuation of a book-
       entry system is no longer in the best interests of the beneficial
       owners of the Class A-1 notes.

      If any of these events occurs, the issuer trustee, at the direction of
the manager, must instruct DTC (or its replacement) to notify all of the
beneficial owners of the Class A-1 notes of the availability of definitive
notes. Class A-1 notes will be serially numbered if issued in definitive form.

      Definitive notes will be transferable and exchangeable at the specified
offices of the Class A-1 note registrar. The Bank of New York, London Branch is
the initial Class A-1 note registrar and its initial specified offices are
located at [           ]. The Class A-1 note registrar will not impose a
service charge for any registration of transfer or exchange, but may require
payment of an amount sufficient to cover any tax or other

                                       67
<PAGE>

governmental charge. The Class A-1 note registrar will not be required to
register the transfer or exchange of definitive notes within the thirty days
preceding a distribution date.

Distributions on the Notes
      Collections in respect of interest and principal will be received during
each quarterly collection period. Collections include the following:

    .  interest and principal receipts from the housing loans;

    .  proceeds from enforcement of the housing loans;

    .  proceeds from claims under the mortgage insurance policies; and

    .  payments by the seller or the servicer relating to breaches of their
       representations or undertakings.

      The issuer trustee will make its payments on a quarterly basis on each
distribution date, including payments to noteholders and redraw bondholders,
from collections received during the preceding collection period and from
amounts received under Support Facilities on or prior to the distribution date.
Certain amounts received by the issuer trustee are not distributed on a
distribution date. These amounts include cash collateral lodged with the issuer
trustee by a Support Facility provider or the seller and interest on that cash
collateral.

Key Dates and Periods
      The following are the relevant dates and periods for the allocation of

Accrual Period...................    means each period commencing on and
                                     including a distribution date and ending
                                     on but excluding the next distribution
                                     date. However, the first and last accrual

Example Calendar
      The following example calendar for a quarter assumes that all relevant
days are Business Days:

  Collection Period.............     July 1st to September 30th
  Determination Date............     October 1st
  Distribution Date.............     October 12th
  Accrual Period................     July 12th to October 11th

Calculation of Available Income Amount
      Payments of interest, fees and amounts otherwise of an income nature,
including payments of interest on the notes and redraw bonds, are made from the
available income amount.

      The Available Income Amount for a determination date and the following
distribution date means the aggregate of:

    .  the Finance Charge Collections for the preceding collection period
       which are the following amounts received by or on behalf of the
       issuer trustee during that collection period:

      .  all amounts received in respect of interest, fees, government
         charges and other amounts due under the housing loans but not
         including principal and any insurance premiums or related charges
         payable to the seller;

      .  all amounts of interest in respect of the housing loans to the
         extent that the obligation to pay is discharged by a right of set-
         off or right to combine accounts; and

      .  break costs but only to the extent that these are not paid to the
         fixed rate swap provider under the fixed rate swap;

    .  the Mortgage Insurance Interest Proceeds for that determination date
       which are amounts received by the issuer trustee under a mortgage
       insurance policy which the manager determines should be accounted for
       on that determination date in respect of a loss of interest, fees,
       charges and certain property protection and enforcement expenses on a
       housing loan;

                                       69
<PAGE>

    .  Other Income for that collection period which means:

      .  certain damages or equivalent, including amounts paid by the
         seller in respect of breaches of representations or warranties in
         relation to the housing loans, in respect of interest or fees on
         the housing loans received from the servicer or seller during the
         collection period;

      .  other damages received by the issuer trustee during the collection
         period from the servicer, the seller or any other person and
         allocated by the manager as other income;

      .  amounts received upon a sale of the housing loans in respect of
         interest or fees if the trust terminates as described under
         "Termination of the Trust";

      .  interest, if any, on the collections account other than interest
         in respect of cash collateral lodged by a Support Facility
         provider or the seller in the collections account;

      .  income earned on Authorized Short-Term Investments received during
         the collection period;

      .  certain tax credits; and

      .  other receipts in the nature of income, as determined by the
         manager, received by the determination date;

    .  any advance under the liquidity facility due to be made on the
       distribution date in order to meet an income shortfall; and

    .  any other amounts received from a Support Facility provider on or
       prior to the distribution date which the manager determines should be
       included in the Available Income Amount.

      Based upon the margins payable by Commonwealth Bank on the basis swap and
the fixed rate swap, and assuming that payments are made when due under the
housing loans, it is expected that there will be sufficient Available Income
Amount to cover all the known obligations of the trust on each distribution
date, including interest on the notes, plus a buffer.

Liquidity Facility Advance
      If the manager determines on any determination date that there is an
income shortfall, the manager must direct the issuer trustee to make a drawing
under the liquidity facility in an amount equal to the lesser of the amount of
the income shortfall and the unutilized portion of the liquidity limit, if any.

      An income shortfall is the amount by which the payments to be made from
the Available Income Amount, other than reimbursement of principal charge-offs
or payment to the residual unitholder, exceed the aggregate of the Finance
Charge Collections, the Mortgage Insurance Interest Proceeds and Other Income
in relation to that distribution date.

Distribution of the Available Income Amount
      On each distribution date, the Available Income Amount for that
distribution date is allocated in the following order of priority:

    .  first, to payment of any taxes of the trust including government
       charges paid by the servicer for the issuer trustee;

    .  second, payment of the issuer trustee's fee;

    .  third, payment of the security trustee's fee;

    .  fourth, payment of the manager's fee;

    .  fifth, payment of the servicer's fee;

    .  sixth, payment of the commitment fee payable under the liquidity

       advances outstanding under the liquidity facility and payments under
       the fixed rate swap and the basis swap, but not including any
       payments under support facilities detailed above or below or which
       are properly payable from the Principal Amount;

    .  eighth, payment of all costs, charges and expenses incurred by the
       issuer trustee in administering the trust, other than as detailed
       above or below or which are payable from the Principal Amount;

    .  ninth, payment of the commitment fee payable under the standby redraw
       facility;

    .  tenth, repayment of any liquidity facility advance made on or prior
       to the previous distribution date and then outstanding;

    .  eleventh, rateably between themselves:

      .  payment to the currency swap provider of the A$ Class A-1 Interest
         Amount in relation to that distribution date and any unpaid A$
         Class A-1 Interest Amounts from prior distribution dates and
         interest on those unpaid amounts, in return for which the currency
         swap provider will pay the principal paying agent for distribution
         to the Class A-1 noteholders as described in "The Currency Swap--
         Interest Payments" below;

      .  payment of interest in relation to the Class A-2 notes for the
         accrual period ending on that distribution date and any unpaid

      .  payment of interest in relation to the redraw bonds for the
         accrual period ending on that distribution date and any unpaid
         interest in relation to the redraw bonds from prior distribution
         dates and interest on that unpaid interest; and

      .  payment of the interest due on that distribution date under the
         standby redraw facility and any interest remaining unpaid from
         prior distribution dates and interest on that unpaid interest;

    .  twelfth, payment of interest in relation to the Class B notes for the
       accrual period ending on that distribution date and any unpaid
       interest in relation to the Class B notes from prior distribution
       dates and interest on that unpaid interest;

    .  thirteenth, to reimburse any principal charge-offs as an allocation
       to the Principal Amount on that distribution date; and

    .  fourteenth, to the residual unitholder.

      The issuer trustee shall only make a payment under the bullet points
above to the extent that any Available Income Amount remains from which to make
the payment after amounts with priority to that payment have been distributed.

      On the first distribution date, prior to any allocation or payment
described above, the issuer trustee will first apply the Available Income
Amount to pay to the seller the Accrued Interest Adjustment.

Interest on the Notes

Calculation of interest payable on the notes
      The period that any notes or redraw bonds accrue interest is divided into
accrual periods. The first accrual period commences on and includes the closing
date and ends on but excludes the first distribution date. Each subsequent
accrual period commences on and includes a distribution date and ends on but
excludes the following distribution date. The final accrual period for the
Class A-1 notes will end on but exclude the date that the Class A-1 notes are
redeemed.

      Up to, but excluding, the distribution date falling in [     ], the
interest rate for the Class A-1 notes for the related accrual period will be
equal to LIBOR for that accrual period plus [  ]%. If the issuer trustee has
not redeemed all of the Class A-1 notes by the distribution date falling in
[     ], then the interest rate for each accrual period commencing on or after
that date will be equal to LIBOR for that accrual period plus [  ]%.

      The interest rates for the Class A-2 notes and the Class B notes for an
accrual period will be equal to the Bank Bill Rate for that accrual period plus
the relevant margin applicable to those notes. The margin applicable to the
Class A-2 notes will increase from the accrual period commencing on the
distribution date in [ ] if the Class A-2 notes have not been redeemed by that
date. If redraw bonds are issued the interest rate applicable to them will be
equal to the Bank Bill Rate plus a margin determined at the time of their
issue. The interest rates for the Class A-2 notes, the Class B notes and the
redraw bonds, if any, for each accrual period are calculated by the manager.

      With respect to any distribution date, interest on a note or any redraw
bond will be calculated as the product of:

    .  the Invested Amount of that note or redraw bond as of the first day
       of that accrual period, after giving effect to any payments of
       principal made with respect to such note or redraw bond on such day;

                                       72
<PAGE>

    .  the interest rate for such note or redraw bond for that accrual
       period; and

    .  a fraction, the numerator of which is the actual number of days in
       that accrual period and the denominator of which is 360 days for the
       Class A-1 notes, or 365 days for the Class A-2 notes, the Class B
       notes and any redraw bonds.

      The Class A-1 notes accrue interest from and including the closing date
to but excluding the earlier of the date on which the Stated Amount of the
Class A-1 notes is reduced to zero and the date upon which the Class A-1 notes
are redeemed.

      Interest will accrue on any unpaid interest in relation to a note or
redraw bond at the interest rate that applies from time to time to that note or
redraw bond until that unpaid interest is paid.

Calculation of LIBOR
      On the second business day in London and New York before the beginning of
each accrual period, the agent bank will determine LIBOR for the next accrual
period.

Determination of the Available Principal Amount
      Payments of principal, including repayment of principal on the notes and
redraw bonds, are made from the Available Principal Amount. The Available
Principal Amount for a determination date and the following distribution date
means the aggregate of:

    .  the Principal Collections for the preceding collection period which
       are all amounts received during the collection period in respect of
       principal on the housing loans, other than principal prepayments, and
       includes principal to the extent that an obligation to pay principal
       on a housing loan is discharged by a right of set-off or right to
       combine accounts;

    .  the Mortgage Insurance Principal Proceeds for the determination date
       which are all amounts received by the issuer trustee under a mortgage
       insurance policy which the manager determines should be accounted for
       on the determination date in respect of a loss of principal and
       certain property restoration expenses on a housing loan;

    .  Other Principal Amounts which are all other amounts in respect of
       principal on the housing loans including:

      .  proceeds of the liquidation of a housing loan following
         enforcement, other than amounts included in Finance Charge
         Collections, received during the collection period;

      .  principal prepayments under the housing loans received during the
         collection period;

      .  certain damages or equivalent, including amounts paid by the
         seller in respect of breaches of representations or warranties in
         relation to the housing loans, in respect of principal received
         from the servicer or the seller during the collection period;

                                       73
<PAGE>

      .  other damages received by the issuer trustee during the collection
         period from the servicer, the seller or any other person and
         allocated by the manager as Other Principal Amounts;

      .  amounts received upon a sale of the housing loans in respect of
         principal if the trust terminates as described under "Termination
         of the Trust";

      .  in relation to the first determination date, the amount, if any,
         by which subscription proceeds of the notes exceed the aggregate
         of the principal outstanding on the housing loans as at the cut-
         off date;

      .  any amount rounded down on payments of principal on the previous
         distribution date; and

      .  any other receipts in the nature of principal as determined by the
         manager which have been received by the determination date;

    .  Principal Charge-Off Reimbursement which is the excess of the
       Available Income Amount for the determination date available to be
       applied towards unreimbursed principal charge-offs;

    .  Standby Redraw Facility Advance which is any advance to be made under
       the standby redraw facility on that distribution date; and

    .  Redraw Bond Amount which is the total subscription proceeds of redraw
       bonds issued on the determination date or during the collection
       period, but after the immediately preceding determination date.

Distribution of the Available Principal Amount
      On each distribution date, the Available Principal Amount for that
distribution date is allocated in the following order of priority:

    .  first, repayment to the seller of any redraws and further advances
       under the housing loans, other than further advances which cause the
       related housing loan to be removed from the trust, made during or
       prior to the collection period then ended and which are then
       outstanding;

    .  second, repayment to the standby redraw facility provider of the
       principal outstanding under the standby redraw facility as reduced by
       any principal charge-offs or increased by any reimbursement of
       principal charge-offs on or prior to that distribution date;

    .  third, equally amongst the redraw bonds in order of their issue until
       their Stated Amounts are reduced to zero on the basis that a redraw
       bond receives no principal repayment until the Stated Amount of all
       earlier issued redraw bonds has been reduced to zero;

    .  fourth, to the currency swap provider in respect of principal
       payments on the Class A-1 notes and amongst the Class A-2 notes and
       the Class B notes in the manner described below under the heading
       "Allocation of Principal to Class A Notes and Class B Notes";

    .  fifth, to the residual unitholder.

                                       74
<PAGE>

      The issuer trustee shall only make a payment under the bullet points
above to the extent that any Available Principal Amount remains from which to
make the payment after amounts with priority to that payment have been
distributed.

Allocation of Principal to Class A Notes and Class B Notes
      That part of the Available Principal Amount which is available on a
distribution date for repayment of the Stated Amount of the Class A and Class B
notes is applied as follows.

      The amount available for repayment of the Stated Amount of the notes,
under the fourth bullet point above, is divided between Net Principal
Collections and Net Unscheduled Principal. The Net Principal Collections are
the remaining Principal Collections available after prior applications in the
preceding three bullet points and the Net Unscheduled Principal is the
remaining Mortgage Insurance Principal Proceeds, Other Principal Amounts,
Principal Charge-off Reimbursement, Standby Redraw Facility Advance and Redraw
Bond Amount after prior applications in the preceding three bullet points. This
is determined on the basis that in applying the Available Principal Amount the
issuer trustee first applies the Mortgage Insurance Principal Proceeds, the
Other Principal Amounts, the Principal Charge-off Reimbursement, the Standby
Redraw Facility Advance and the Redraw Bond Amount and then, only after these
have been applied in full, applies the Principal Collections.

      The amount to be applied towards repayment of the Stated Amount of the
Class A notes on a distribution date is determined as follows:

      The amount to be applied to repayment is:

        where:

<TABLE>
      <S>                <C>               <C>             <C>              <C>               <C>
       (NPC+NUP)X        SACAN)               +             (NUPX             SACBN             XSP)
       (                  SAN )                             (                  SAN                 )
</TABLE>

    .  NPC is the Net Principal Collections;

    .  NUP is the Net Unscheduled Principal;

    .  SACAN is the aggregate Stated Amount of the Class A notes on the
       preceding determination date, converted, in the case of the Class A-1
       notes, to Australian dollars at the A$ Exchange Rate;

    .  SACBN is the aggregate Stated Amount of the Class B Notes on the
       preceding determination date;

    .  SAN is the aggregate Stated Amount of all notes on the preceding
       determination date, converted, in the case of the Class A-1 notes, to
       Australian dollars at the A$ Exchange Rate; and

    .  SP is the Stepdown Percentage.

                                       75
<PAGE>

      The effect of the above calculation is that Class A noteholders receive
their proportional share of the Net Principal Collections and the Net
Unscheduled Principal (based upon the Stated Amounts of the notes) and also
receive the Stepdown Percentage (which may vary between 0% and 100%) of the
Class B noteholders' proportional share of the Net Unscheduled Principal. The
remaining part of the Available Principal Amount is applied towards repayment
of the Stated Amount of the Class B notes.

      The amount to be applied towards repayment of the Stated Amount of the
Class A notes on the distribution date is applied rateably based upon the
aggregate Stated Amounts of the Class A-1 and A-2 notes converted, in the case
of the Class A-1 notes, to Australian dollars at the A$ Exchange Rate, towards:

    .  payment to the currency swap provider in respect of repayment of the
       Stated Amount of the Class A-1 notes;

    .  payment equally amongst the Class A-2 notes in reduction of the
       Stated Amount of the Class A-2 notes,

until the Stated Amount of the Class A notes is reduced to zero.

      The balance of the Net Principal Collections and the Net Unscheduled
Principal is applied on that distribution date equally amongst the Class B
notes in reduction of the Stated Amount of the Class B notes until the Stated
Amount of the Class B notes is reduced to zero.

Redraws and Further Advances
      The seller may make redraws and further advances to borrowers under the
housing loans. The seller is entitled to be reimbursed by the issuer trustee
for redraws and further advances other than further advances which cause the
related housing loan to be removed from the trust. The seller will be
reimbursed from the Available Principal Amount including proceeds of advances
under the standby redraw facility and proceeds from the issue of redraw bonds.

Standby Redraw Facility
      If the manager determines that there is a redraw shortfall on a
determination date, the manager may direct the issuer trustee in writing to
make a drawing under the standby redraw facility on a distribution date equal
to the lesser of the redraw shortfall and the unutilized portion of the redraw
limit, if any.

      A redraw shortfall is the amount by which the redraws and further
advances to be repaid to the seller on that distribution date exceed the
aggregate of the Principal Collections, the Mortgage Insurance Principal
Proceeds, the Other Principal Amounts and the Principal Charge-off
Reimbursement in relation to that distribution date.

Issue of Redraw Bonds
      If prior to a determination date the manager considers that the aggregate
of the Principal Collections, the Mortgage Insurance Principal Proceeds, the
Other Principal

                                       76
<PAGE>

Amounts, the Principal Charge-off Reimbursement in relation to the
determination date and the Standby Redraw Facility Advance that will be
available to be made with respect to the following distribution date are likely
to be insufficient to pay in full the manager's estimate of:

    .  the redraws and further advances to be repaid to the seller on that
       distribution date; and

    .  the outstanding principal under the standby redraw facility as
       reduced by any principal charge-offs or increased by any
       reimbursement of principal charge-offs [on or prior to that
       distribution date],

the manager may direct the issuer trustee to issue redraw bonds. The manager
must not direct the issuer trustee to issue redraw bonds unless it considers
that on the following distribution date, taking into account that issue of
redraw bonds and any repayments of principal and principal charge-offs or
reimbursement of principal charge-offs on the redraw bonds expected on that
distribution date, the aggregate Stated Amount of all redraw bonds will not
exceed on that distribution date A$[50,000,000] or such other amount agreed
between the manager and the rating agencies and notified to the issuer trustee.

      Before issuing any redraw bonds, the issuer trustee must receive written
confirmation from each rating agency that the proposed issue of redraw bonds
will not result in a reduction, qualification or withdrawal of any credit
rating assigned by that rating agency to a note or redraw bond. The redraw
bonds will be denominated in Australian dollars and issued only in Australia.

Principal Charge-offs
      In certain circumstances, amounts which are unrecoverable under a housing
loan will be absorbed by reducing the Stated Amount of a note or redraw bond or
by reducing the principal outstanding in respect of the standby redraw
facility. That reduction of the Stated Amount of a note or redraw bond or the
principal outstanding of the standby redraw facility is referred to as a
principal charge-off.

Application of Principal Charge-Offs
      If the manager determines on a determination date that a principal loss
should be accounted for in respect of a housing loan, after taking into account
proceeds of enforcement of that housing loan and its securities, any relevant
payments under a mortgage insurance policy or damages from the servicer or the
seller, that principal loss will be allocated in the following order:

    .  first, equally amongst the Class B notes until the Stated Amount of
       the Class B notes is reduced to zero; and

    .  secondly, rateably amongst the following based, in the case of the
       notes or redraw bonds, on their Stated Amount converted, in the case
       of the Class A-1 notes, to Australian dollars at the A$ Exchange
       Rate:

      .  the Class A-1 notes;

                                       77
<PAGE>

      .  the Class A-2 notes;

      .  the redraw bonds; and

      .  the principal outstanding of the standby redraw facility,

      until the Stated Amount of the Class A-1 and A-2 notes, the redraw
      bonds and the principal outstanding of the standby redraw facility is
      reduced to zero.

      To the extent allocated, the principal loss will reduce the Stated Amount
of the notes and redraw bonds and will reduce the principal outstanding of the
standby redraw facility as from the following distribution date. The principal
loss allocated is an Australian dollar amount. Where this is allocated to a
Class A-1 note, the Stated Amount of the Class A-1 note is reduced by an
equivalent US dollar amount converted at the US$ Exchange Rate.

Reimbursements of Principal Charge-Offs
      Principal charge-offs may be reimbursed on a subsequent distribution date
where there is excess income available after payment of all fees, expenses and
interest on that distribution date. Reimbursement of principal charge-offs will
only occur to the extent that there are unreimbursed principal charge-offs and
will be allocated in the following order:

    .   first rateably amongst the following based on their unreimbursed
        principal charge-offs converted, in the case of the Class A-1 notes,
        to Australian dollars at the A$ Exchange Rate:

      .   the Class A-1 notes;

      .   the Class A-2 notes;

      .   the redraw bonds; and

      .   the principal outstanding of the standby redraw facility,

      in reduction of their unreimbursed charge-offs until these are
      reduced to zero; and

    .   second, equally amongst the Class B notes until the unreimbursed
        charge-offs of the Class B notes are reduced to zero.

      A reimbursement of a principal charge-off on a note or redraw bond will
increase the Stated Amount of that note or redraw bond and a reimbursement of a
principal charge-off on the standby redraw facility will increase the principal
outstanding of the standby redraw facility but the actual funds allocated in
respect of the reimbursement will be distributed as described in "Distribution
of the Available Principal Amount" above.

      The amounts allocated for reimbursement of principal charge-offs are
Australian dollar amounts. Where such an amount is allocated to a Class A-1
note, the Stated Amount of the Class A-1 note is increased by an equivalent
U.S. dollar amount converted at the US$ Exchange Rate.

The Interest Rate Swaps

Purpose of the Interest Rate Swaps
      Collections in respect of interest on the variable rate housing loans
will be calculated based on the servicer's administered variable rates.
Collections in respect of interest on the fixed rate housing loans will be
calculated based on the relevant fixed rates. However, the payment obligations
of the issuer trustee on the Class A-2 notes and the Class B notes and under
the currency swap are calculated by reference to the Bank Bill Rate. To hedge
these interest rate exposures, the issuer trustee will enter into the basis
swap with the basis swap provider and the fixed rate swap with the fixed rate
swap provider . The basis swap and the fixed rate swap will be governed by a
standard form ISDA Master Agreement, as amended by a supplementary schedule and
confirmed by written confirmations in relation to each swap.

Basis Swap
      On each distribution date the issuer trustee will pay to the basis swap
provider an amount calculated by reference to the aggregate principal amount
outstanding of the variable rate housing loans as at the previous distribution
date and the weighted average of the interest rates charged on the variable
rate housing loans.

      In return the basis swap provider will pay to the issuer trustee on each
distribution date an amount calculated by reference to the aggregate principal
amount outstanding of the variable rate housing loans as at the previous
distribution date and the Bank Bill Rate plus a margin.

      The basis swap will terminate on the distribution date in [   ]. See
"Description of the Transaction Documents--Servicing of the Housing Loans--
Administer Interest Rates" in relation to the servicer's obligations with
respect to interest rates on the variable rate housing loans if the basis swap
is terminated.

Fixed Rate Swap
      On each distribution date the issuer trustee will pay to the fixed rate
swap provider an amount calculated by reference to the aggregate principal
amount outstanding of the fixed rate housing loans as at the previous
distribution date and the weighted average of the interest rates charged on the
fixed rate housing loans.

      In return the fixed rate swap provider will pay to the issuer trustee on
each distribution date an amount calculated by reference to the aggregate
principal amount outstanding of the fixed rate housing loans as at the previous
distribution date and the Bank Bill Rate plus a margin.

      In addition, if a borrower prepays a loan subject to a fixed rate of
interest, or otherwise terminates a fixed rate period under a housing loan, the
issuer trustee will normally be entitled to receive from the borrower a break
cost or the issuer trustee will be required to pay to the borrower a break
benefit.

                                       79
<PAGE>

      A break cost is currently payable by the borrower to the issuer trustee
where the terminated fixed rate under the housing loan is greater than the
current equivalent fixed rate product offered by the seller for the remaining
term of the housing loan. Under the seller's current policies and procedures,
prepayments of up to $5,000 in any 12 month period may be made by a borrower
without incurring break costs, see "Commonwealth Bank Residential Loan
Program--Special Features of the Housing Loans--Early Repayment." A break
benefit is payable by the issuer trustee to the borrower where the terminated
fixed rate under the housing loan is less than the equivalent fixed rate
product offered by the seller for the remaining term of the housing loan. If
the break period is not a whole year an interpolated rate is used.

      While the fixed rate swap is operating the net difference between break
costs and break benefits for all housing loans for a collection period is
either paid by the fixed rate swap provider, where the difference is a negative
number, or paid to the fixed rate swap provider, where the difference is a
positive number, on each distribution date. While the fixed rate swap is
operating, break costs are not included within the Available Income Amount and
break benefits are not considered to be expenses of the trust.

      The method for calculation of break costs and break benefits may change
from time to time according to the business judgment of the servicer.

Termination by the Basis Swap and Fixed Rate Swap Provider
      The basis swap and fixed rate swap provider will each have the right to
terminate the basis swap and the fixed rate swap, respectively, in the
following circumstances:

    .   if the issuer trustee fails to make a payment under either swap
        within 10 days after notice of failure is given to the issuer
        trustee;

    .   if due to a change in law it becomes illegal for either party to
        make or receive payments, perform its obligations under any credit
        support document or comply with any other material provision of the
        basis swap or the fixed rate swap. However, only a swap affected by
        the illegality may be terminated and if the basis swap and fixed
        rate swap provider is the party affected by the illegality it must
        make efforts to transfer its rights and obligations to avoid this
        illegality; or

    .   in the case of the basis swap only, if the basis swap provider
        ceases to have short term credit ratings of P-1 from Moody's, A-1+
        from Standard & Poor's and F1+ from Fitch IBCA as described under
        "Basis Swap Provider Downgrade" below.

Termination by the Issuer Trustee
      The issuer trustee will have the right to terminate the basis swap or the
fixed rate swap in the following circumstances:

    .   if the swap provider fails to make a payment within 10 days after
        notice of failure is given to the swap provider; or

    .   if due to a change in law it becomes illegal for either party to
        make or receive payments, perform its obligations under any credit
        support document or comply

                                       80
<PAGE>

       with any other material provision of the basis swap or the fixed rate
       swap. However, only a swap affected by the illegality may be
       terminated and if the basis swap and fixed rate swap provider is the
       party affected by the illegality it must make certain efforts to
       transfer its rights and obligations to avoid this illegality.

Fixed Rate Swap Provider Downgrade
      If, as a result of the withdrawal or downgrade of its credit rating by
any rating agency, on any determination date the fixed rate swap provider does
not have:

    .   [either a long term credit rating of at least AA- by Standard &
        Poor's or] a short term credit rating of at least A-1+ by Standard &
        Poor's;

    .   a long term credit rating of at least A2 by Moody's; and

    .   a short term rating of at least F1+ by Fitch,

the fixed rate swap provider must:

    .   obtain a counterparty acceptable to the manager, the issuer trustee,
        and the rating agencies to enter into a swap with the issuer trustee
        on substantially the same terms as the fixed rate swap;

    .   prepay its obligations under the fixed rate swap by depositing an
        amount into the [collections account] which the relevant rating
        agencies confirm will not result in a reduction, qualification or
        withdrawal of any credit rating assigned by them to the notes or
        redraw bonds (which amount will be adjusted on each following
        determination date based on the requirements of the rating
        agencies); or

    .   enter into other arrangements satisfactory to the issuer trustee and
        the manager which each rating agency confirms will not result in a
        reduction, qualification or withdrawal of any credit rating assigned
        by it to the notes or redraw bonds.

Basis Swap Provider Downgrade
      If, as a result of the withdrawal or downgrade of its credit rating by
any rating agency, on any determination date the basis swap provider does not
have:

    .   a short term credit rating of at least A-1+ by Standard & Poor's;

    .   a long term credit rating of at least A2 by Moody's; and

    .   a short term rating of at least F1+ by Fitch,

the basis swap provider must:

    .   terminate the basis swap;

    .   on each of the following distribution dates prepay the amount that
        would otherwise be due from the basis swap provider to the issuer
        trustee on the next distribution date; or

    .   enter into other arrangements satisfactory to the issuer trustee and
        the manager which each rating agency confirms will not result in a
        reduction, qualification or withdrawal of any credit rating assigned
        by it to the notes or redraw bonds.

                                       81
<PAGE>

Termination Payments
      Upon termination of the fixed rate swap, a termination payment will be
due from the issuer trustee to the fixed rate swap provider or from the fixed
rate swap provider to the issuer trustee.

      The termination payment in respect of fixed rate swap will be determined,
if possible, on the basis of quotations from leading dealers in the relevant
market 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 fixed rate swap.

      No termination payment will be payable in respect of the termination of
the basis swap.

      If the basis swap terminates then, unless and until the issuer trustee
has entered into a replacement basis swap or other arrangements which the
rating agencies have confirmed will not result in a reduction, qualification or
withdrawal of the credit ratings assigned to the notes or redraw bonds, the
servicer must, subject to applicable laws including the Consumer Credit Code,
adjust the interest rates charged on the variable rate housing loans. The
interest rates must be adjusted to a level which will be sufficient, assuming
that all the parties to the transaction documents and the housing loans comply
with their obligations under the transaction documents and the housing loans,
when aggregated with the income produced by the rate of interest on all the
other housing loans and the income from Authorized Short-Term Investments, to
ensure the issuer trustee will have sufficient collections to enable it to
comply with its obligations under the transaction documents as they fall due.

The Currency Swap

Purpose of the Currency Swap
      Collections on the housing loans and receipts under the basis swap and
the fixed rate swap will be denominated in Australian dollars. However, the
payment obligations of the issuer trustee on the Class A-1 notes are
denominated in United States dollars. In addition, receipts by the issuer
trustee under the basis swap and the fixed rate swap are calculated by
reference to the Bank Bill Rate but the interest obligations of the issuer
trustee with respect to the Class A-1 notes are calculated by reference to
LIBOR. To hedge this currency and interest rate exposure, the issuer trustee
will enter into a currency swap agreement with the currency swap provider. The
currency swap will be governed by a standard form ISDA Master Agreement, as
amended by a supplementary schedule and confirmed by a written confirmation.

Principal Payments
      On the closing date, the issuer trustee will pay the currency swap
provider the U.S. dollar proceeds of issue of the Class A-1 notes. In return,
the currency swap provider will pay to the issuer trustee the Australian dollar
equivalent of the proceeds of issue of the Class A-1 notes converted at the US$
Exchange Rate.


                                       82
<PAGE>

      On each distribution date, the issuer trustee will pay to the currency
swap provider the Australian dollar amount available to be applied towards
repayment of the Stated Amount of the Class A-1 notes. In return, the currency
swap provider will pay to the principal paying agent on behalf of the issuer
trustee the U.S. dollar equivalent of that amount converted at the A$ Exchange
Rate for distribution to the Class A-1 noteholders in accordance with the
agency agreement in reduction of the Stated Amount of the Class A-1 notes.

Interest Payments
      On each distribution date, the issuer trustee will pay to the currency
swap provider an amount, the A$ Class A-1 Interest Amount, calculated by
reference to the Australian dollar equivalent of the aggregate Invested Amount
of the Class A-1 notes as at the preceding distribution date converted at the
US$ Exchange Rate and the Bank Bill Rate plus a margin.

      In return, the currency swap provider will pay to the principal paying
agent on behalf of the issuer trustee the interest due in respect of the Class
A-1 notes on that distribution date for distribution to Class A-1 noteholders
in accordance with the agency agreement.

      If the issuer trustee does not have sufficient funds under the series
supplement to pay the full amount owing to the currency swap provider in
respect of the above payment the currency swap provider is not required to make
the corresponding payment to the principal paying agent and, after the
applicable grace period, the currency swap provider may terminate the currency
swap. The manner of determining whether the issuer trustee will have sufficient
funds to pay the currency swap provider that amount on a distribution date is
described in "Distribution of the Available Income Amount" above. A failure of
the issuer trustee to pay an amount owing under the currency swap, if not
remedied within the applicable grace period, will be an event of default under
the security trust deed.

Termination by the Currency Swap Provider
      The currency swap provider will have the right to terminate the currency
swap in the following circumstances:

    .   if the issuer trustee fails to make a payment under the currency
        swap within 10 days after notice of failure is given to the issuer
        trustee;

    .   if due to a change in or a change in interpretation of law it
        becomes illegal other than as a result of the introduction of
        certain exchange controls by an Australian governmental body for
        either party to make or receive payments, perform its obligations
        under any credit support document or comply with any other material
        provision of the currency swap. However, if the currency swap
        provider is the party affected by the illegality, it must make
        efforts to transfer its rights and obligations to avoid this
        illegality; and

    .   if due to any action taken by a taxation authority or a change in
        tax law the currency swap provider is required to gross-up payments
        on account of a non-resident withholding tax liability or receive
        payments from which amounts have been withheld or deducted on
        account of tax. However, the currency swap

                                       83
<PAGE>

       provider will only have the right to terminate the currency swap if
       the Class A-1 note trustee is satisfied that all amounts owing to
       Class A-1 noteholders will be paid in full on the date on which the
       Class A-1 notes are to be redeemed.

Termination by the Issuer Trustee
      The issuer trustee will have the right to terminate the currency swap in
the following circumstances:

    .   if the currency swap provider fails to make a payment under the
        currency swap within 10 days after notice of failure is given to the
        currency swap provider;

    .   if certain bankruptcy related events occur in relation to the
        currency swap provider;

    .   if the currency swap provider merges with, or otherwise transfers
        all or substantially all of its assets to, another entity and the
        new entity does not assume all of the obligations of the currency
        swap provider under the currency swap;

    .   if due to a change in or a change in interpretation of law it
        becomes illegal other than as a result of the introduction of
        certain exchange controls by an Australian governmental body for
        either party to make or receive payments, perform its obligations
        under any credit support document or comply with any other material
        provision of the currency swap. However, if the currency swap
        provider is the party affected by the illegality, it must make
        efforts to transfer its rights and obligations to avoid this
        illegality;

    .   if due to any action taken by a taxation authority or a change in
        tax law the issuer trustee is required to receive payments from
        which amounts have been withheld or deducted on account of tax and
        no entitlement to a corresponding gross-up arises other than as a
        result of its failure to perform certain tax covenants or, in
        certain circumstances, a breach of its tax representations;

    .   if as a result of the currency swap provider merging with, or
        otherwise transferring all or substantially all its assets to
        another entity, the issuer trustee is required to receive payments
        from which a deduction or withholding has been made on account of a
        non-resident withholding tax liability and no entitlement to a
        corresponding gross-up arises other than as a result of its failure
        to perform certain tax covenants, or, in certain circumstances, a
        breach of its tax representations; and

    .   if the currency swap provider fails to comply with its obligations
        described in "Currency Swap Provider Downgrade" below following a
        downgrade of its credit ratings, and that failure is not remedied
        within 10 Business Days of notice of the failure being given to the
        currency swap provider or such other period as the issuer trustee
        and the manager agree and the rating agencies confirm will not
        result in a reduction, qualification or withdrawal of the credit
        ratings assigned by them to the Class A-1 notes.

The issuer trustee may only terminate the currency swap with the prior written
consent of the Class A-1 note trustee.

                                      84
<PAGE>

Termination by the Class A-1 Note Trustee
      If following an event that allows the issuer trustee or the currency swap
provider to terminate the currency swap the relevant party does not terminate
the currency swap, the Class A-1 note trustee may terminate the currency swap.

Currency Swap Provider Downgrade
      If, as a result of the withdrawal or downgrade of its credit rating by
any rating agency, the currency swap provider does not have:

    .   either a long term credit rating of at least AA- by Standard &
        Poor's or a short term credit rating of at least A-1+ by Standard &
        Poor's;

    .   a long term credit rating of at least A2 by Moody's; and

    .   a long term rating of at least AA- by Fitch,

the currency swap provider must within:

    .   30 days, if the currency swap provider still has either a long term
        credit rating of at least A- by Standard & Poor's or a short term
        credit rating of at least A-1 by Standard & Poor's, and a long term
        credit rating of at least A2 by Moody's and a long term rating of at
        least A- by Fitch; or

    .   5 days, in any other case,

or, in either case, such greater period as is agreed to in writing by the
relevant rating agency, at its cost and at its election:

    .   lodge cash collateral in US$, in an amount determined by the
        relevant rating agencies or, in certain circumstances, determined
        under the currency swap, in an account held by the issuer trustee
        with a financial institution outside Australia which has the highest
        short-term credit rating from each rating agency;

    .   enter into an agreement novating the currency swap to a replacement
        counterparty proposed by the currency swap provider or the manager
        and, if proposed by the currency swap provider, acceptable to the
        manager and which each rating agency has confirmed will not result
        in there being a reduction, qualification or withdrawal of any
        credit rating assigned by it to the Class A-1 notes; or

    .   enter into other arrangements which each rating agency has confirmed
        will not result in there being a reduction, qualification or
        withdrawal of any credit rating assigned by it to the Class A-1
        notes.

      If the currency swap provider lodges cash collateral with the issuer
trustee, any interest on that cash collateral will be paid to the currency swap
provider.

Termination Payments
      Upon termination of the currency swap, a termination payment will be due
from the issuer trustee to the currency swap provider or from the currency swap
provider to the issuer trustee.

                                       85
<PAGE>

      The termination payment in respect of the currency swap will be
determined, if possible, on the basis of quotations from leading dealers in the
relevant market 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 the Currency Swap
      If the currency swap is terminated prior to its scheduled termination
date, the issuer trustee may, at the direction of the manager, enter into one
or more replacement currency swaps on terms and with a counterparty which the
rating agencies confirm will not result in a reduction, qualification or
withdrawal of the credit ratings assigned by them to the Class A-1 notes. A
termination payment received by the issuer trustee upon termination of the
currency swap may be applied towards a premium payable to enter into a
replacement currency swap and a premium received by the issuer trustee upon
entering into a new currency swap may be applied towards a termination payment
in respect of the terminated currency swap.

Partial Redemption of the Class A-1 Notes on Distribution Dates
      On each distribution date until the Stated Amount of the Class A-1 notes
is reduced to zero the issuer trustee must:

    .  pay to the currency swap provider, in accordance with the directions
       of the manager, the Australian dollar amount allocated to repayment
       on that distribution date of principal on the Class A-1 notes as
       described in "Allocation of Principal to Class A Notes and Class B
       Notes";

    .  direct the currency swap provider to pay on that distribution date
       the U.S. dollar equivalent of that Australian dollar amount,
       converted at the US$ Exchange Rate, to the principal paying agent;
       and

    .  direct the principal paying agent to pay that amount received from
       the currency swap provider rateably to the Class A-1 noteholders
       towards repayment of the Stated Amounts of the Class A-1 notes in
       accordance with the agency agreement and the terms and conditions of
       the Class A-1 notes.

Withholding or Tax Deductions
      All payments in respect of the Class A-1 notes will be made without
withholding or tax deduction for, or on account of, any present or future
taxes, duties or charges of whatever 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-1 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 agents, as the case
may be, shall make such payment after such withholding or deduction has been
made, it 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 obligated to make any additional payments to holders of the Class A-1
notes with respect to that withholding or deduction. Immediately after becoming
aware that such a withholding or deduction is or will be required, the issuer
trustee will notify the Class A-1 note trustee, the paying agent and the Class
A-1 noteholders.

Redemption of the Notes for Taxation or Other Reasons
      If the manager satisfies the issuer trustee and the Class A-1 note
trustee, immediately before giving the notice to the Class A-1 noteholders as
described in this section, that because of a change of law in Australia or any
other jurisdiction to which the issuer trustee becomes subject either:

    .  on the next distribution date the issuer trustee would be required to
       deduct or withhold from any payment of principal or interest in
       respect of any class of

                                       87
<PAGE>

       notes or redraw bonds 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 a
       government or authority of Australia or such other jurisdiction; or

    .  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 a government or authority
       of Australia or such other jurisdiction,

and in each case such obligation cannot be avoided by the issuer trustee taking
reasonable measures available to it, then the issuer trustee must, when so
directed by the manager, at the manager's option, redeem all, but not some, of
the notes and redraw bonds at their then Invested Amounts, in the case of the
Class A notes and redraw bonds, subject to the following, or at their Stated
Amounts, in the case of the Class B notes, together with accrued but unpaid
interest to but excluding the date of redemption. The issuer trustee may redeem
the Class A notes and redraw bonds at their Stated Amounts, instead of at their
Invested Amounts, together with accrued but unpaid interest to but excluding
the date of redemption, if so approved by an Extraordinary Resolution of Class
A noteholders and redraw bondholders together.

      However, the issuer trustee will not redeem the notes or redraw bonds
unless it is in a position on the relevant distribution date to repay the then
Invested Amounts or Stated Amounts, as required, of the notes and the redraw
bonds together with all accrued but unpaid interest to but excluding the date
of redemption and to discharge all its liabilities in respect of amounts which
are required under the security trust deed to be paid in priority to or equally
with the notes or redraw bonds if the charge under the security trust deed were
enforced.

      Class A-1 noteholders must be given notice of a redemption not more than
60 nor less than 45 days prior to the date of redemption.

      If a tax, duty or other amount described above applies only to the Class
A-1 notes and the issuer trustee gives notice that it proposes to redeem the
notes and the redraw bonds, the holders of 75% of the aggregate Stated Amount
of the Class A-1 notes may elect, in accordance with the terms of the Class A-1
note trust deed, that they do not require the issuer trustee to redeem the
Class A-1 notes. Upon being notified of such an election at least 21 days
before the distribution date upon which redemption was to occur the issuer
trustee must not redeem the notes or redraw bonds.

Redemption of the Notes upon an Event of Default
      If an event of default occurs under the security trust deed the security
trustee must, subject to certain conditions, in accordance with an
Extraordinary Resolution of Voting Secured Creditors and the provisions of the
security trust deed, enforce the security created

                                       88
<PAGE>

by the security trust deed. That enforcement can include the sale of some or
all of the housing loans. 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.

Optional Redemption of the Notes
      The issuer trustee must, when directed by the manager, at the manager's
option, redeem all of the notes and the redraw bonds at their then Invested
Amounts, in the case of the Class A notes and redraw bonds, subject to the
following, or at their Stated Amounts in the case of the Class B notes,
together with accrued but unpaid interest to, but excluding, the date of
redemption, on any distribution date falling on or after the earlier of:

    .  the date on which the total principal outstanding on the housing
       loans is less than 10% of the total principal outstanding on the
       housing loans on [    ]; and

    .  the distribution date falling in [    ],

The issuer trustee may redeem the Class A notes and redraw bonds at their
Stated Amounts instead of at their Invested Amounts, together with accrued but
unpaid interest to but excluding the date of redemption, if so approved by an
Extraordinary Resolution of Class A noteholders and redraw bondholders
together. However, the issuer trustee will not redeem the notes or redraw bonds
unless it is in a position on the relevant distribution date to repay the then
Invested Amounts or the Stated Amounts, as required, of the notes and the
redraw bonds together with all accrued but unpaid interest to but excluding the
date of redemption and to discharge all its liabilities in respect of amounts
which are required under the security trust deed to be paid in priority to or
equally with the notes or redraw bonds if the charge under the security trust
deed were enforced.

      Class A-1 noteholders must be given notice of a redemption not more than
60 nor less than 45 days prior to the date of redemption.

Final Maturity Date
      Unless previously redeemed, the issuer trustee must redeem the notes and
redraw bonds by paying the Stated Amount, together with all accrued and unpaid
interest, in relation to each note and redraw bond on or by the distribution
date falling in [ ].

Redemption upon Final Payment
      Upon final distribution being made in respect of any notes or redraw
bonds following termination of the trust or enforcement of the charge under the
security trust deed, those notes or redraw bonds will be deemed to be redeemed
and discharged in full and any obligation to pay any accrued but unpaid
interest, the Stated Amount or the Invested Amount in relation to the notes or
redraw bonds will be extinguished in full.

No Payments of Principal in Excess of Stated Amount
      No amount of principal will be repaid in respect of a note or redraw bond
in excess of its Stated Amount or, in the case of an optional redemption or
redemption for taxation reasons, its Invested Amount.

                                       89

Termination of the Trust

Termination of Trust
      Following the issue of the notes the trust may only terminate prior to
the redemption of the notes if the issuer trustee gives notice to the manager
that as a result of the introduction, imposition or variation of any law it is
unlawful for the issuer trustee, and that it would also be unlawful for any new
issuer trustee, to carry out any of its obligations under the series
supplement.

Sale of Housing Loans Upon Termination
      Upon termination of the trust, the issuer trustee in consultation with
the manager must sell and realize the assets of the trust within 180 days of
the termination date. During this period the issuer trustee is not entitled to
sell the housing loans and their related securities, mortgage insurance
policies and other rights for less than the aggregate Fair Market Value of the
housing loans. The issuer trustee is only entitled to sell the housing loans
and their related securities, mortgage insurance policies and other rights to a
person other than the seller if the seller does not exercise its right of first
refusal. The issuer trustee must not conclude a sale unless, among other
things, any housing loans and their related securities, mortgage insurance
policies and other rights are assigned in equity only, except if the issuer
trustee already has legal title, and the sale is expressly subject to the
servicer's right to be retained as servicer and subject to the rights of the
CBA trust and to the rights of the seller as beneficiary of the CBA trust in
respect of those housing loans and their related securities, mortgage insurance
policies and other rights, as described in "Description of the Assets of the
Trust--Transfer and Assignment of the Housing Loans."

      If the issuer trustee is unable to sell the housing loans and their
related securities and mortgage insurance policies for Fair Market Value and on
those terms during the 180 day period, it may then sell them free of the
restrictions and may perfect its legal title if necessary to obtain Fair Market
Value for the housing loans. However upon such a sale the issuer trustee must
use reasonable endeavors to include as a condition of the sale that a purchaser
will agree to the seller taking second mortgages in order to retain second
ranking security for the other loans secured by the mortgage and to entering
into a priority agreement to give the seller second priority for its second
mortgage and to use reasonable endeavours to obtain the consent of the relevant
borrowers and security providers to the seller's second mortgage.

Seller's First Right of Refusal
      On the termination date of the trust, the issuer trustee is deemed to
offer to sell the housing loans and their related securities, mortgage
insurance policies and other rights to the seller for at least the aggregate
Fair Market Value of the housing loans.

      The issuer trustee must not sell the housing loans and their related
securities, mortgage insurance policies and other rights unless the seller has
failed to accept that offer within 90 days of the termination date of the trust
or has failed to pay the purchase price within 180 days of the termination date
of the trust.


                                       90
<PAGE>

Distributions
      The issuer trustee must deposit the proceeds of realization of the assets
of the trust into the collections account and, following the realization of all
the assets of the trust, must distribute them on a distribution date in
accordance with the order of priority described in "Description of the Class A-
1 Notes--Distribution of Available Income Amount" and "Description of the Class
A-1 Notes-- Distribution of Available Principal Amount." The amount distributed
will be in full and final redemption of all of the notes and redraw bonds.

Prescription
      A Class A-1 note will be void in its entirety if not surrendered for
final payment within ten years of the relevant date in respect of that payment
on the Class A-1 note. The relevant date is 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 Class A-1 note trustee on or prior to that
date, it means the date on which the full amount of such money having been so
received and notice to that effect is duly given in accordance with the terms
of the relevant Class A-1 note. After the date on which a Class A-1 note
becomes void in its entirety, no claim may be made in respect of it.

Directions by Class A-1 Noteholders
      Under the Class A-1 note trust deed the Class A-1 note trustee may seek
directions from the Class A-1 noteholders from time to time including following
the occurrence of an event of default under the security trust deed.

      The Class A-1 note trustee will not be responsible for acting in good
faith upon a direction given, or purporting to be given, by Class A-1
noteholders holding Class A-1 notes with a Stated Amount of greater than 50% of
the aggregate Stated Amount of all the Class A-1 notes.

      If the Class A-1 note trustee is entitled under the master trust deed or
the security trust deed to vote at any meeting on behalf of Class A-1
noteholders the Class A-1 note trustee must vote in accordance with the
directions of the Class A-1 noteholders and otherwise in its absolute
discretion. In acting in accordance with the directions of Class A-1
noteholders the Class A-1 note trustee must exercise its votes for or against
any proposal to be put to a meeting in the same proportion as that of the
aggregate Stated Amounts of the Class A-1 notes held by Class A-1 noteholders
who have directed the Class A-1 note trustee to vote for or against that
proposal.

      For the purposes of seeking any consent, direction or authorisation from
Class A-1 noteholders the Class A-1 note trustee may by notice to the Class A-1
noteholders specify a date not earlier than the date of the notice upon which
the persons who are the Class A-1 noteholders and the Stated Amount of the
Class A-1 notes held by them will be determined based upon the details recorded
in the Class A-1 note register as at 5.30pm on that date.

Amendments to Class A-1 Notes and Class A-1 Note Trust Deed
      The issuer trustee, the manager and the Class A-1 note trustee, may
alter, add to or revoke any provision of the Class A-1 note trust deed or the
Class A-1 notes, subject to the

                                       91
<PAGE>

limitations described below, if the alteration, addition or revocation is not a
Payment Modification and, in the opinion of the Class A-1 note trustee:

    .   is made to correct a manifest error or ambiguity or is of a formal,
        technical or administrative nature only;

    .   is necessary or expedient to comply with the provisions of any law
        or regulation or with the requirements of any statutory authority;

    .   is appropriate or expedient as a consequence of an alteration to any
        law or regulation or altered requirements of the government of any
        jurisdiction or any governmental agency including an alteration,
        addition or revocation which is appropriate or expedient as a result
        of an alteration to Australia's tax laws or any ruling by the
        Australian Commissioner or Deputy Commissioner of Taxation or any
        governmental announcement or statement which has or may have the
        effect of altering the manner or basis of taxation of trusts
        generally or of trusts similar to the trust or to the trust under
        the Class A-1 note trust deed;

    .   is otherwise desirable for any reason and:

      .   is not in the opinion of the Class A-1 note trustee likely, upon
          coming into effect, to be materially prejudicial to the interests
          of the Class A-1 noteholders; or

      .   if it is in the opinion of the Class A-1 note trustee likely,
          upon coming into effect, to be materially prejudicial to the
          interests of the Class A-1 noteholders, the consent of Class A-1
          noteholders owning 75% of the aggregate outstanding principal
          balance of the Class A-1 notes is obtained.

      Any alteration, addition or revocation must be notified to the rating
agencies 5 Business Days in advance.

      The Class A-1 note trustee will be entitled to assume that any proposed
alteration, addition or revocation will not be materially prejudicial to the
interests of Class A-1 noteholders if each of the rating agencies confirms in
writing that the alteration, addition or revocation, if effected, will not lead
to a reduction, qualification or withdrawal of the rating given to the Class A-
1 notes by that rating agency.

      The issuer, the manager and the Class A-1 note trustee may make any
Payment Modification to the Class A-1 note trust deed or the Class A-1 notes
only if the consent has first been obtained of each Class A-1 Noteholder to the
Payment Modification.

      Payment Modification means any alteration, addition or revocation of any
provision of the Class A-1 note trust deed or the Class A-1 notes which
modifies:

    .   the amount, timing, currency or manner of payment of principal or
        interest in respect of the Class A-1 Notes or the rights of Class A-
        1 Noteholders to institute suit for enforcement of such payment;

                                       92
<PAGE>

    .   the manner of determining whether Class A-1 noteholders owning 75%
        of the aggregate outstanding principal balance of the Class A-1
        notes have provided a consent or direction or the circumstances in
        which such a consent or direction is required; or

    .   the requirements for altering, adding to or revoking any provision
        of the Class A-1 note trust deed or the Class A-1 notes.

      The issuer trustee must distribute to all Class A-1 noteholders a copy of
any amendment made as soon as reasonably practicable after the amendment has
been made.

Reports to Noteholders
      On each [distribution] date, the manager will, in respect of the
collection period ending before that [distribution] date, deliver to the
principal paying agent, the note trustee and the issuer trustee, and the
principal paying agent will deliver to the Class A-1 noteholders, a quarterly
servicing report containing the following information:

    .   the Invested Amount and the Stated Amount of each class of notes;

    .   the interest payments and principal distributions on each class of
        notes;

    .   the Available Income Amount;

    .   the aggregate of all redraws made during that quarterly collection
        period;

    .   the redraw shortfall, if any;

    .   the income shortfall, if any;

    .   the liquidity facility draws, if any, for that collection period,
        together with all liquidity facility draws before the start of that
        collection period and not repaid;

    .   the Available Principal Amount;

    .   the Principal Collections;

    .   the Standby Redraw Facility Advance;

    .   the Redraw Bond Amount;

    .   the Principal Charge-Off, if any;

    .   the Principal Charge-Off Reimbursement, if any;

    .   the note factor for each class of notes, which with respect to a
        class of notes, means the aggregate of the Invested Amount of the
        class of notes less all principal payments on that class of notes to
        be made on that distribution date, divided by the aggregate initial
        Invested Amount for all of that class of notes;

    .   the charge-offs for each class of notes;

    .   if required, the threshold rate at that distribution date;

                                       93
<PAGE>

    .   the interest rates on the notes for the related accrual period;

    .   scheduled and unscheduled payments of principal on the housing
        loans;

    .   aggregate outstanding principal balance of the fixed rate housing
        loans and the aggregate principal balance of the variable rate
        housing loans; and

    .   delinquency and loss statistics with respect to the housing loans.

      Unless and until definitive Class A-1 notes are issued, beneficial owners
of the Class A-1 notes 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 or by way of information published on a
Reuters Screen or the electronic information system made available to
subscribers by Bloomberg L.P. or a similar electronic reporting service.

      Unless and until definitive Class A-1 notes are issued, periodic and
annual unaudited reports containing information concerning the trust and the
Class A-1 notes will be prepared by the manager and sent to DTC. DTC and its
participants will make such reports available to holders of interests in the
Class A-1 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 Class A-1 notes are in book-entry form. Upon
the issuance of Class A-1 notes in definitive form such reports will be sent
directly to each Class A-1 noteholder. Such reports will not constitute
financial statements prepared in accordance with generally accepted accounting
principles.

      The manager will file with the SEC such periodic reports as are required
under the Exchange Act, and the rules and regulations of the SEC thereunder.
However, in accordance with the Exchange Act and the rules and regulations of
the SEC thereunder, the manager expects that the obligation to file such
reports will be terminated following the end of June, 2001.

                    Description of the Transaction Documents

      The following summary describes the material terms of the transaction
documents other than the underwriting agreement and the dealer agreement and
except as already described above. The summary does not purport to be complete
and is subject to the provisions of the transaction documents. The transaction
documents are governed by the laws of New South Wales, Australia. A copy of the
master trust deed and a form of each of the other transaction documents have
been filed as exhibits to the registration statement of which this prospectus
is a part.

Collections Account and Authorized Short-Term Investments
      The issuer trustee will establish and maintain the collections account
with an Eligible Depositary. The collections account will initially be
established with Commonwealth Bank, which has a short term rating of F1+ from
Fitch IBCA, P-1 from Moody's and A-1+ from Standard & Poor's at its office at
[    ]. The collections account shall be opened by the

                                       94
<PAGE>

issuer trustee in its name and in its capacity as trustee of the trust. The
collections account will not be used for any purpose other than for the trust.
The account will be an interest bearing account.

      If the financial institution with which the collections account is held
ceases to be an Eligible Depositary the issuer trustee must establish a new
account with an Eligible Depositary as a replacement collections account.

      The manager shall have the discretion to propose to the issuer trustee,
in writing, the manner in which any moneys forming part of the trust shall be
invested in Authorized Short-Term Investments and what purchases, sales,
transfers, exchanges, realizations or other dealings with assets of the trust
shall be effected and when and how they should be effected. Provided that they
meet certain requirements, the issuer trustee must give effect to the manager's
proposals. Each investment of moneys required for the payment of liabilities of
the trust shall be in Authorized Short-Term Investments that will mature on or
before the due date for payment of those liabilities.

Modifications of the Master Trust Deed and Series Supplement
      The issuer trustee and the manager, with respect to the master trust
deed, and the issuer trustee, the manager, the seller and the servicer, with
respect to the series supplement, may amend, add to or revoke any provision of
the master trust deed or the series supplement, subject to the limitations
described below, if the amendment, addition or revocation:

    .   in the opinion of the issuer trustee is necessary to correct a
        manifest error or is of a formal, technical or administrative nature
        only;

    .   in the opinion of the issuer trustee, or of a lawyer instructed by
        the issuer trustee, is necessary or expedient to comply with the
        provisions of any law or regulation or with the requirements of any
        statutory authority;

    .   in the opinion of the issuer trustee is required by, a consequence
        of, consistent with or appropriate or expedient as a consequence of
        an amendment to any law or regulation or altered requirements of the
        government of any jurisdiction or any governmental agency,
        including, an amendment, addition or revocation which is appropriate
        or expedient as a result of an amendment to Australia's tax laws or
        any 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
        Medallion Programme trusts;

    .   in the case of the master trust deed, relates only to a Medallion
        Programme trust not yet constituted;

    .   in the opinion of the issuer trustee, will enable the provisions of
        the master trust deed or the series supplement to be more
        conveniently, advantageously, profitably or economically
        administered; or


                                       95
<PAGE>

    .   in the opinion of the issuer trustee is otherwise desirable for any
        reason.

Any amendment, addition or revocation referred to in the last two of the above
paragraphs which in the opinion of the issuer trustee is likely to be
prejudicial to the interests of:

    .   the residual unitholder, may only be effected with the consent of
        the residual unitholder;

    .   a class of noteholders or redraw bondholders, may only be effected
        if those noteholders or redraw bondholders pass a resolution by a
        majority of not less than 75% of the votes at a meeting approving
        the amendment, addition or revocation or all such noteholders or
        redraw bondholders sign a resolution approving the amendment,
        addition or revocation, subject to the following paragraph; or

    .   all noteholders and redraw bondholders, may only be effected if the
        noteholders and redraw bondholders pass a resolution by a majority
        of not less than 75% of the votes at a meeting approving the
        amendment, addition or revocation or all noteholders and redraw
        bondholders sign a resolution approving the amendment, addition or
        revocation. A separate resolution will not be required in relation
        to any class of noteholders or redraw bondholders.

The manager must advise the rating agencies no less than 10 Sydney business
days prior to any amendment, addition or revocation of the master trust deed or
the series supplement and must certify to the issuer trustee that no rating
agency has advised that the amendment, addition or revocation will cause a
withdrawal, downgrading or qualification of the credit ratings assigned to the
notes or redraw bonds before the amendment, addition, or revocation is
effected. The issuer trustee may not amend, add to or revoke any provision of
the master trust deed or the series supplement if the consent of a party is
required under a transaction document unless that consent has been obtained.

The Issuer Trustee

General Duties of Issuer Trustee
      The issuer trustee is appointed as trustee of the trust on the terms set
out in the master trust deed and the series supplement.

      Subject to the provisions of the master trust deed, the issuer trustee
has all the powers in respect of the assets of the trust which it could
exercise if it were the absolute and beneficial owner of the assets. The issuer
trustee agrees to act in the interests of the residual unitholder, the
noteholders and the redraw bondholders. If there is a conflict between the
interests of the residual unitholder on the one hand and the noteholders and
redraw bondholders on the other hand, the issuer trustee must act in the
interests of the noteholders and the redraw bondholders.

      The issuer trustee must act honestly and in good faith in performance of
its duties and in exercising its discretions under the master trust deed, use
its best endeavors to carry on and conduct its business in so far as it relates
to the master trust deed and the series

                                       96
<PAGE>

supplement in a proper and efficient manner and 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 noteholders, redraw bondholders and the
residual unitholder.

      The terms of the master trust deed and series supplement provide, amongst
other things, that:

    .   the obligations of the issuer trustee to the noteholders expressed
        in the master trust deed or the series supplement are contractual
        obligations only and do not create any relationship of trustee or
        fiduciary between the issuer trustee and the noteholders;

    .   the issuer trustee has no duty, and is under no obligation, to
        investigate whether a Manager Default, a Servicer Default or a
        Perfection of Title Event has occurred in relation to the trust
        other than where it has actual notice;

    .   unless actually aware to the contrary, the issuer trustee is
        entitled to rely conclusively on, and is not required to investigate
        the accuracy of any calculation by the seller, the servicer or the
        manager under the series supplement, the amount or allocation of
        collections or the contents of any certificate provided to the
        issuer trustee by the servicer or manager under the series
        supplement;

    .   the issuer trustee may obtain and act on the advice of experts,
        whether instructed by the issuer trustee or the manager, which are
        necessary, usual or desirable for the purpose of enabling the issuer
        trustee to be fully and properly advised and informed and will not
        be liable for acting in good faith on such advice; and

    .   the issuer trustee will only be considered to have knowledge or
        awareness of, or notice of, a thing or grounds to believe anything
        by virtue of the officers of the issuer trustee who have day-to-day
        responsibility for the administration or management of the issuer
        trustee's obligations in relation to the trust, having actual
        knowledge, actual awareness or actual notice of that thing, or
        grounds to believe that thing.

Annual Compliance Statement
      The issuer trustee will deliver to the Class A-1 note trustee annually a
written statement as to the fulfilment of the issuer trustee's obligations
under the Class A-1 note trust deed including compliance with its material
obligations under the transaction documents.

Delegation
      In exercising its powers and performing its obligations and duties under
the master trust deed, the issuer trustee may delegate any or all of the
powers, discretions and authorities of the issuer trustee under the master
trust deed or otherwise in relation to the trust, to a related company of the
issuer trustee or otherwise in accordance with the master trust deed or series
supplement, including, in respect of its payment obligations in respect of

                                       97
<PAGE>

the Class A-1 notes, to the paying agents under the agency agreement. The
issuer trustee at all times remains liable for the acts or omissions of such
related company when acting as delegate.

Issuer Trustee Fees and Expenses
      The issuer trustee is entitled to a quarterly fee based on [the aggregate
outstanding principal balance of the housing loans on the first day of each
collection period], payable in arrears on the following distribution date. The
issuer trustee's fee is calculated to cover the fees payable to the Class A-1
note trustee and the agents which are paid by the issuer trustee from its own
personal funds.

      The fee payable to the issuer trustee may be varied as agreed between the
issuer trustee and the manager provided that each rating agency must be given 3
Business Day's prior notice of any variation and the fee must not be varied if
this would result in a reduction, qualification or withdrawal of the credit
rating of any note or redraw bond.

      The issuer trustee will be indemnified and is entitled to be reimbursed
out of the assets of the trust for costs, charges and expenses which it may
incur in respect of and can attribute to the trust including, amongst other
costs, disbursements in connection with the assets of the trust, the auditing
of the trust, taxes payable in respect of the trust, legal costs and amounts in
connection with the exercise of any power or discretion or the performance of
any obligation in relation to the trust approved by the manager which approval
is not to be unreasonably withheld.

Removal of the Issuer Trustee
      The issuer trustee is required to retire as issuer trustee following an
Issuer Trustee Default. If the issuer trustee refuses to retire following an
Issuer Trustee Default the manager may remove the issuer trustee immediately,
or, if the Issuer Trustee Default relates only to a change in ownership or
merger without assumption of the issuer trustee, upon 30 days notice in
writing.

      The manager must use reasonable endeavors to appoint a qualified
substitute issuer trustee who is approved by the ratings agencies within 30
days of the retirement or removal of the issuer trustee. Until a substitute
issuer trustee is appointed, the manager must act as issuer trustee and will be
entitled to receive the issuer trustee's fee.

      If after 30 days the manager is unable to appoint a qualified substitute
issuer trustee who is approved by the ratings agencies, it must convene a
meeting of all debt security holders, including the noteholders and redraw
bondholders, and all beneficiaries, including the residual unitholder, of all
the Medallion Programme trusts under the master trust deed at which a
substitute issuer trustee may be appointed by resolution of not less than 75%
of the votes at that meeting or by a resolution in writing signed by all debt
security holders and beneficiaries.


                                       98
<PAGE>

Voluntary Retirement of the Issuer Trustee
      The issuer trustee may resign on giving to the manager not less than 3
months' notice in writing, or such lesser period as the manager and the issuer
trustee may agree, of its intention to do so.

      Upon retirement, the issuer trustee must appoint a qualified substitute
issuer trustee who is approved by the ratings agencies and the manager. If the
issuer trustee does not propose a substitute issuer trustee at least one month
prior to its proposed retirement, the manager may appoint a qualified
substitute issuer trustee who is approved by the ratings agencies.

      If a substitute issuer trustee has not been appointed upon the expiry of
the 3 month notice period, the manager will act as issuer trustee. If the
manager is unable to appoint a qualified substitute issuer trustee within a
further 30 days, it must convene a meeting of all debt security holders,
including the noteholders and redraw bondholders, and all beneficiaries,
including the residual unitholder, of all the Medallion Programme trusts under
the master trust deed at which a substitute issuer trustee may be appointed by
resolution of not less than 75% of the votes at that meeting or by a resolution
in writing signed by all debt security holders and beneficiaries.

      The retiring issuer trustee must indemnify the manager and the substitute
issuer trustee in respect of all costs incurred as a result of its removal or
retirement.

Limitation of the Issuer Trustee's Liability
      The issuer trustee acts as trustee and issues the notes only in its
capacity as trustee of the trust and in no other capacity. A liability incurred
by the issuer trustee acting as trustee of the trust under or in connection
with the transaction documents, except with respect to the following paragraph,
is limited to and can be enforced against the issuer trustee only to the extent
to which it can be satisfied out of the assets of the trust out of which the
issuer trustee is actually indemnified for the liability. Except in the
circumstances described in the following paragraph, this limitation of the
issuer trustee's liability applies despite any other provisions 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 notes, the redraw bonds, the
master trust deed the series supplement or any other transaction document.
Noteholders, redraw bondholders and the parties to the transaction documents
may not sue the issuer trustee in respect of liabilities incurred by it acting
as trustee of the trust in any capacity other than as trustee of the trust and
may not seek to appoint a liquidator or administrator to the issuer trustee or
to appoint a receiver to the issuer trustee, except in relation to the assets
of the trust and may not prove in any liquidation, administration or
arrangements of or affecting the issuer trustee, except in relation to the
assets of the trust.

      The limitation in the previous paragraph will 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

                                       99
<PAGE>

indemnification out of the assets of the trust as a result of the issuer
trustee's fraud, negligence or wilful default or the fraud, negligence or
wilful default of its officers, employees or agents or any person for whom the
issuer trustee is liable under the terms of the transaction documents. For
these purposes a wilful default does not include a default which arises as a
result of a breach of a transaction document by any other person, other than
any person for whom the issuer trustee is liable under the terms of the
transaction documents, or which is required by law or a proper instruction or
direction of a meeting of Secured Creditors of the trust or noteholders,
bondholders or other debt security holders or beneficiaries of a Medallion
Program trust.

      In addition, the manager, the servicer, the agents, the Class A-1 note
trustee and other persons are responsible for performing a variety of
obligations in relation to the trust. An act or omission of the issuer trustee
will not be considered to be fraudulent, negligent or a wilful default to the
extent to which it was caused or contributed to by any failure by any such
person to fulfil its obligations relating to the trust or by any other act or
omission of such a person.

Rights of Indemnity of Issuer Trustee
      The issuer trustee is indemnified out of the assets of the trust for any
liability properly incurred by the issuer trustee in performing or exercising
any of its powers or duties. This indemnity is in addition to any indemnity
allowed to the issuer trustee by law, but does not extend to any liabilities
arising from a breach of trust by the issuer trustee or from the issuer
trustee's fraud, negligence or wilful default.

      The issuer trustee is indemnified out of the assets of the trust against
certain payments it may be liable to make under the Consumer Credit Code. The
servicer also indemnifies the issuer trustee in relation to such payments in
certain circumstances and the issuer trustee is required to first call on the
indemnity from the servicer before calling on the indemnity from the assets of
the trust. See "Legal Aspects of the Housing Loans--Consumer Credit Code."

The Manager

Powers
      The manager's general duty is to manage the assets of the trust which are
not serviced by the servicer. In addition, the manager has a number of specific
responsibilities including making all necessary determinations to enable the
issuer trustee to make the payments and allocations required on each
distribution date in accordance with the series supplement, directing the
issuer trustee to make those payments and allocations, keeping books of account
and preparing the tax returns of the trust and monitoring support facilities.

      The manager must act honestly and in good faith in performance of its
duties and in exercising its discretions under the master trust deed, use its
best endeavors to carry on and conduct its business in so far as it relates to
the master trust deed and the other transaction documents in a proper and
efficient manner and exercise such prudence as a prudent person

                                      100
<PAGE>

of business would exercise in performing its express functions and in
exercising its discretions under the master trust deed and the other
transaction documents having regard to the interests of noteholders, redraw
bondholders and the residual unitholder.

Delegation
      The manager may, in carrying out and performing its duties and
obligations in relation to the trust, appoint any person as attorney or agent
of the manager with such powers as the manager thinks fit including the power
to sub-delegate provided that the manager may not delegate a material part of
its duties and obligations in relation to the trust. The manager remains liable
for the acts or omissions of such attorneys or agents to the extent that the
manager would itself be liable.

Manager's Fees, Expenses and Indemnification
      The manager is entitled to a quarterly fee based on [the aggregate
outstanding principal balance of the housing loans on the first day of each
collection period], payable in arrears on the following distribution date.

      The fee payable to the manager may be varied as agreed between the issuer
trustee and the manager provided that each rating agency must be given 3
Business Day's prior notice of any variation and the fee must not be varied if
this would result in a reduction, qualification or withdrawal of the credit
rating of any note or redraw bond.

      The manager will be indemnified out of the assets of the trust for any
liability, cost or expense properly incurred by it in its capacity as manager
of the trust.

Removal or Retirement of the Manager
      If the issuer trustee becomes aware that a Manager Default has occurred
and is subsisting the issuer trustee must immediately terminate the appointment
of the manager and must appoint a substitute manager in its place. The manager
indemnifies the issuer trustee in respect of all costs incurred as a result of
its replacement by the issuer trustee.

      The manager may retire on giving to the issuer trustee 3 months, or such
lesser period as the manager and the issuer trustee may agree, notice in
writing of its intention to do so. Upon its retirement, the manager may appoint
another corporation approved by the issuer trustee as manager in its place. If
the manager does not propose a replacement by the date one month prior to the
date of its retirement the issuer trustee may appoint a replacement manager as

number of limitations on the manager's liability are set out in full in the
master trust deed and the other transaction documents. These include the

       omission of the issuer trustee, the seller or the servicer; or

    .  caused by its failure to check any calculation, information,
       document, form or list supplied or purported to be supplied to it by
       the issuer trustee, the seller, the servicer or any other person,

except to the extent that they are caused by the manager's own fraud,
negligence or wilful default.

Limits on Rights of Noteholders and Redraw Bondholders
      Apart from the security interest arising under the security trust deed,
the noteholders and redraw bondholders do not own and have no interest in the

       trust;

    .  require the transfer to it of any asset of the trust;

    .  interfere with or question the exercise or non-exercise of the rights

       the trust;

    .  lodge a caveat or other notice forbidding the registration of any

    .  take proceedings against the issuer trustee, the manager, the seller
       or the servicer or in respect of the trust or the assets of the
       trust. This will not limit the right of noteholders and redraw
       bondholders to compel the issuer trustee, the manager

                                      102

       under the master trust deed, the series supplement, the Class A-1
       note trust deed and the security trust deed, in the case of the
       issuer trustee and the manager, and the security trust deed, in the
       case of the security trustee;

    .  have any recourse to the issuer trustee or the manager in their

The Security Trust Deed

General
      P.T. Limited of Level 7, 39 Hunter Street, Sydney, Australia is the
security trustee. The issuer trustee will grant a first ranking floating
charge, registered with the Australian Securities and Investments Commission,
over all of the trust assets in favor of the security trustee. The floating
charge will secure the issuer trustee's obligations to the noteholders, the
redraw bondholders, the servicer, the Class A-1 note trustee, each paying
agent, the seller, the liquidity facility provider, the standby redraw facility
provider and each swap provider. These secured parties are collectively known
as the Secured Creditors.

Nature of the Charge
      A company may not deal with its assets over which it has granted a fixed
charge without the consent of the relevant chargee. Fixed charges are usually
given over real property, marketable securities and other assets which will not
be dealt with by the company.

      A floating charge, like that created by the security trust deed, does not
attach to specific assets but instead "floats" over a class of assets which may
change from time to time. The company granting the floating charge may deal
with those assets and 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 company's business. The issuer trustee has agreed not to dispose
of or create interests in the assets of the trust subject to the floating
charge except in accordance with the master trust deed, the series supplement
or the security trust deed and the manager has agreed not to direct the issuer
trustee to take any such actions. If the issuer trustee disposes of any of the
trust assets, including any housing loan, in accordance with the master trust
deed, the series supplement or the security trust deed, the person acquiring
the property will take it free of the floating charge. The floating charge
granted over the trust assets will crystalize, which means it becomes a fixed
charge, upon the occurrence of an event of default or will become fixed over
the affected assets in the case of certain events of default. [On
crystallization of the floating charge, the issuer trustee may not deal with
the assets of the trust unless permitted in accordance with the master trust
deed, the series supplement or any other transaction document.]


                                      105

The Security Trustee
      The security trustee is appointed to act as trustee on behalf of the
Secured Creditors and holds the benefit of the charge over the trust assets in
trust for each Secured Creditor on the terms and conditions of the security
trust deed. If, in the security trustee's opinion, there is a conflict between
the duties owed by the security trustee to any Secured Creditor or class of
Secured Creditors and the interests of noteholders and redraw bondholders as a
whole, the security trustee must give priority to the interests of the
noteholders and redraw bondholders. In addition, the security trustee must give
priority to the interests of the Class A noteholders and redraw bondholders if,
in the security trustee's opinion, there is a conflict between the interests of
Class A noteholders and redraw bondholders and the interests of the Class B
noteholders.

Duties and Liabilities of the Security Trustee
      The security trustee's liability to the Secured Creditors is limited to
the amount the security trustee is entitled to recover through its right of
indemnity from the assets held on trust by it under the security trust deed.
However, this limitation will not apply to the extent that the security trustee
limits its right of indemnity as a result of its own fraud, negligence or
wilful default.

      The security trust deed contains a range of other provisions regulating
the scope of the security trustee's duties and liabilities. These include the
following:

    .  the security trustee is not required to monitor whether an event of
       default has occurred or compliance by the issuer trustee or manager
       with the transaction documents or their other activities;

    .  the security trustee is not required to do anything unless its
       liability is limited in a manner satisfactory to it;

    .  the security trustee is not responsible for the adequacy or
       enforceability of any transaction documents;

    .  except as expressly stated in the security trust deed, the security
       trustee need not give to the Secured Creditors information concerning
       the issuer trustee or the trust which comes into the possession of
       the security trustee;

    .  the issuer trustee gives wide ranging indemnities to the security
       trustee in relation to its role as security trustee; and

    .  the security trustee may rely on documents and information provided
       by the issuer trustee or manager.

Events of Default
      Each of the following is an event of default under the security trust
deed:

    .  the issuer trustee retires or is removed, or is required to retire or
       be removed, as trustee of the trust and is not replaced within 30
       days and the manager fails within a further 20 days to convene a
       meeting of debt security holders and beneficiaries of the Medallion
       Program trusts;

                                      106
<PAGE>

    .  the security trustee has actual notice or is notified by the manager
       or the issuer trustee that the issuer trustee is not entitled for any
       reason to fully exercise its right of indemnity against the assets of
       the trust to satisfy any liability to a Secured Creditor and the
       circumstances are not rectified to the reasonable satisfaction of the
       security trustee within 14 days of the security trustee requiring
       this;

    .  the trust is not properly constituted or is imperfectly constituted
       in a manner or to an extent that is regarded by the security trustee
       acting reasonably to be materially prejudicial to the interests of
       any class of Secured Creditor and is incapable of being, or is not
       within 30 days, remedied;

    .  an Insolvency Event occurs in respect of the issuer trustee in its
       capacity as trustee of the trust;

    .  distress or execution is levied or a judgment, order or encumbrance
       is enforced, or becomes enforceable, over any of the assets of the
       trust for an amount exceeding A$1,000,000, either individually or in
       aggregate, or can be rendered enforceable by the giving of notice,
       lapse of time or fulfilment of any condition;

    .  the charge under the security trust deed:

      .  is or becomes wholly or partly void, voidable or unenforceable; or

      .  loses its priority, subject only to the Prior Interest, as a first
         ranking charge, other than as mandatorily preferred by law or by
         an act or omission of the security trustee;

    .  subject only to the Prior Interest, the issuer trustee attempts to
       create or allows to exist a security interest over the assets of the
       trust otherwise than in accordance with the master trust deed, the
       series supplement or the security trust deed;

    .  the Australian Commissioner of Taxation, or its delegate, determines
       to issue a notice under section 74 of the Sales Tax Assessment Act
       1992, section 34 of the Taxation Administration Act, 1953 or sections
       260-5 to 260-20 of the Taxation Administration Act 1953 or section
       218 or 255 of the Income Tax Assessment Act 1936 for any amount due
       by the issuer trustee in respect of any tax under any such Act or any
       fines and costs imposed on the issuer trustee or a governmental
       agency takes any other steps which will result in an amount of tax or
       an amount owing to a governmental agency ranking ahead of the charge
       with respect to any charged property; and

    .  any Secured Moneys are not paid within 10 days of when due, other
       than amounts due to the Class B noteholders.

The security trustee may determine that any event that would otherwise be an
event of default under the security trust deed will not be treated as an event
of default, where this will not in the opinion of the security trustee be
materially prejudicial to the interests of the Secured Creditors. However, it
must not do so in contravention of any prior directions in an Extraordinary
Resolution of Voting Secured Creditors. Unless the security trustee has made

                                      107
<PAGE>

such an election, and providing that the security trustee is actually aware of
the occurrence of an event of default, the security trustee must promptly
convene a meeting of the Voting Secured Creditors at which it shall seek at
directions from the Voting Secured Creditors by way of Extraordinary Resolution
regarding the action it should take as a result of that event of default.

Meetings of Voting Secured Creditors
      The security trust deed contains provisions for convening meetings of the
Voting Secured Creditors to enable the Voting Secured Creditors to direct or
consent to the security trustee taking or not taking certain actions under the
security trust deed, including directing the security trustee to enforce the
security trust deed. Meetings may also be held of a class or classes of Voting
Secured Creditors under the security trust deed.

Voting Procedures
      Every question submitted to a meeting of Voting Secured Creditors shall
be decided in the first instance by a show of hands. If a show of hands results
in a tie, the chairman shall both on a show of hands and on a poll have a
casting vote. A representative is a person or body corporate appointed as a
proxy for a Voting Secured Creditor or a representative of a corporate Voting
Secured Creditor under the Australian Corporations Law. 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. If at any meeting a poll
is demanded, every person who is present shall have one vote for every A$10 of
Secured Moneys owing to it, converted, in the case of the Class A-1
noteholders, to Australian dollars at the A$ Exchange Rate if the currency swap
has not been terminated or else at the spot rate as determined by the security
trustee on the Business Day prior to the meeting, or in which he or she is a
representative.

      A resolution of all the Voting Secured Creditors, 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 Secured Creditors.

Enforcement of the Charge
      At a meeting of Voting Secured Creditors called following an event of
default under the security trust deed the Voting Secured Creditors must vote on
whether to direct the security trustee by Extraordinary Resolution to do any or
all of the following:

    .  declare all Secured Moneys immediately due and payable;

    .  appoint a receiver over the trust assets and determine the
       remuneration to be paid to that receiver;

    .  sell and realize the assets of the trust; or

    .  take any other action which the security trustee indicates that it is
       willing to take.


                                      108
<PAGE>

      Any enforcement action taken by the security trustee will only relate to
the same rights in relation to the assets of the trust as are held by the
issuer trustee. This means that even after an enforcement, the security
trustee's interest in the assets of the trust will remain subject to the rights
of the seller and the servicer arising under the master trust deed and the
series supplement.

      No Secured Creditor 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.

The Class A-1 Note Trustee as Voting Secured Creditor
      If an event of default under the security trust deed occurs and is
continuing, the Class A-1 note trustee must deliver notice of that event to
each Class A-1 noteholder within [10] days, or sooner if required by the rules
of the London Stock Exchange or any other stock exchange on which the Class A-1
notes are listed, of becoming aware of that event provided that, except in the
case of a default in payment of interest and principal on the Class A-1 notes,
the note trustee may withhold such notice if it determines in good faith that
withholding the notice is in the interests of Class A-1 noteholders.

      The rights, remedies and discretion of the Class A-1 noteholders under
the security trust deed, 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 Class A-1 note trustee on behalf of
the Class A noteholders except in limited circumstances as specified in the
security trust deed. The security trustee may rely on any instructions or
directions given to it by the Class A-1 note trustee as being given on behalf
of the Class A-1 noteholders without inquiry about compliance with the Class A-
1 note trust deed.

      If any of the Class A-1 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-1 notes, the Class A-1 note trustee must not vote under the security trust
deed to, or otherwise direct the security trustee to enforce the charge or
dispose of the assets of the trust unless:

    .   a sufficient amount would be realized to discharge in full all
        amounts owing to the Class A-1 noteholders, and any other amounts
        payable by the issuer trustee ranking in priority to or equal with
        the Class A-1 notes;

    .   the Class A-1 note trustee is of the opinion, reached after
        considering at any time and from time to time the advice of a
        investment bank or other financial adviser selected by the Class A-1
        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 the preceding paragraph; or

    .   the Class A-1 note trustee is so directed by the holders of 75% of
        the aggregate Stated Amount of the Class A-1 notes.

                                      109

Limitations of Actions by the Security 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 an Extraordinary Resolution of the Voting Secured
Creditors in accordance with the security trust deed, unless in the opinion of
the security trustee the delay required to obtain such directions would be
prejudicial to Secured Creditors as a class. The security trustee is not
obligated to act unless it obtains an indemnity from the Voting Secured
Creditors 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.

      If the security trustee convenes a meeting of the Voting Secured
Creditors, or is required by an Extraordinary Resolution to take any action
under the security trust deed, and advises the Voting Secured Creditors that it
will not act in relation to the enforcement of the security trust deed unless
it is personally indemnified by the Voting Secured Creditors to its reasonable
satisfaction against all actions, proceedings, claims and demands to which it
may render itself liable, and all costs, charges, damages and expenses which it
may incur in relation to the enforcement of the security trust deed and is put
in funds to the extent to which it may become liable, including costs and
expenses, and the Voting Secured Creditors refuse to grant the requested
indemnity, and put the security trustee in funds, then the security trustee is
not obliged to act in relation to that enforcement under the security trust
deed. In those circumstances, the Voting Secured Creditors may exercise such of
those powers conferred on them by the security trust deed as they determine by
Extraordinary Resolution.

Priorities under the Security Trust Deed
      The proceeds from the enforcement of the charge are to be applied in the
following order of priority, subject to any statutory or other priority which
may be given priority by law:

    .   first, rateably to pay amounts owing or payable under the security
        trust deed to indemnify the security trustee against all loss and
        liability incurred by the security trustee or any receiver in acting
        under the security trust deed, except the receiver's remuneration,
        and in payment of the Prior Interest;

    .   second, to pay rateably any fees due to the security trustee, the
        Class A-1 note trustee or the principal paying agent and the
        receiver's remuneration;

    .   third, to pay rateably other outgoings and liabilities that the
        receiver, the security trustee or the Class A-1 note trustee have
        incurred in acting under the security trust deed, and, in the case
        of the Class A-1 note trustee, under the Class A-1 note trust deed;

    .   fourth, to pay any security interests over the assets of the trust
        of which the security trustee is aware having priority to the charge
        under the security trust deed, other than the Prior Interest, in the
        order of their priority;


                                      110
<PAGE>

    .   fifth, to pay the Class A-1 noteholders the proceeds, if any, of any
        termination payment received from the currency swap provider toward
        satisfaction of any secured moneys owing in relation to the Class A-
        1 Notes;

    .   sixth, to pay the liquidity facility provider any unutilized cash
        collateral lodged with the issuer trustee and any unpaid interest on
        that cash collateral;

    .   seventh, to pay the seller any unpaid Accrued Interest Adjustment;

    .   eighth, to pay rateably:

      .   the Class A noteholders and redraw bondholders all Secured Moneys
          owing in relation to the Class A notes and redraw bonds. For the
          purposes of calculating the Class A-1 entitlement, the Secured
          Moneys owing in respect of the Class A-1 notes will be converted
          from US dollars to Australian dollars at the A$ exchange rate or
          the spot exchange rate upon the termination of the currency swap,
          as determined by the security trustee in each case, which ever
          rate produces the lesser amount of Australian dollars. This will
          be applied:

             .   first, rateably towards all unpaid interest on the Class A
                 notes and redraw bonds; and

             .   second, rateably to reduce the Stated Amount of the Class A
                 notes and redraw bonds;

      .   any other Secured Moneys owing to the liquidity facility
          provider;

      .   any Secured Moneys owing to the standby redraw facility provider;

      .   rateably all Secured Moneys owing to each swap provider; and

      .   all unpaid redraws and further advances owing to the seller and
          the seller deposit;

    .   ninth, if the Secured Moneys owing to the Class A-1 noteholders were
        converted under the preceding paragraph from US dollars to
        Australian dollars at the spot exchange rate upon the termination of
        the currency swap and, as a result, fewer US$ than the US$ amount
        owing to the Class A-1 noteholders were paid to the Class A-1
        noteholders, equally amongst the Class A-1 notes in respect of any
        remaining US$ amounts owing to the Class A-1 noteholders converted
        at the spot exchange rate, as determined by the security trustee, 2
        Business Days prior to the date of distribution;

    .   tenth, equally to the Class B noteholders;

    .   eleventh, to pay rateably to each Secured Creditor any monetary
        liabilities owing to that Secured Creditor under any transaction
        document and not satisfied under the preceding paragraphs;

                                      111
<PAGE>

    .   twelfth, to pay subsequent security interests over the assets of the
        trust of which the security trustee is aware, in the order of their
        priority; and

    .   thirteenth, to pay any surplus to the issuer trustee to be
        distributed in accordance with the terms of the master trust deed and
        the series supplement. The surplus will not carry interest as against
        the security trustee.

Payments to Class A-1 noteholders will be effected in US$, which will be
calculated by re-converting the Australian dollar amount due to Class A-1
noteholders to US$ using the spot exchange rate 2 Business Days prior to the
date of distribution.

     Upon enforcement of the security created by the security trust deed, the
net proceeds may be insufficient to pay all amounts due on redemption to the
noteholders and redraw bondholders. Any claims of the noteholders and redraw
bondholders remaining after realization of the security and application of the
proceeds shall be extinguished.

Security Trustee's Fees and Expenses
     The issuer trustee shall reimburse the security trustee for all costs and
expenses of the security trustee incurred in performing its duties under the
security trust deed. The security trustee shall receive a fee in the amount
agreed from time to time by the issuer trustee, the security trustee and the
manager provided that the rating agencies must be given prior notice of any
variation of the fee and the fee may not be varied if this would result in a
reduction, qualification or withdrawal of the credit rating of any note or
redraw bond.

Retirement and Removal of the Security Trustee
     The security trustee may retire on 3 months notice. The security trustee
must retire if:

    .   an Insolvency Event occurs with respect to it;

    .   it ceases to carry on business;

    .   the issuer trustee, where it is a related body corporate, retires or
        is removed from office and the manager requires the security trustee
        by notice in writing to retire;

    .   the Voting Secured Creditors require it to retire by an Extraordinary
        Resolution;

    .   it breaches a material duty and does not remedy the breach with 20
        Business Days notice from the manager or the issuer trustee; or

    .   there is a change in ownership or effective control of the security
        trustee without the consent of the manager.

     If the security trustee retires, it may appoint an authorized trustee
corporation to act in its place with the approval of the manager and the
rating agencies. If the security trustee is removed, the issuer trustee, or
failing it the manager, may appoint a replacement security trustee which is an
authorized trustee corporation under the Australian Corporations Law with the
approval of the rating agencies.

     If a substitute security trustee has not been appointed at a time when
the position of security trustee becomes vacant, the manager must act as
security trustee and must promptly convene a meeting of Voting Secured
Creditors who may by Extraordinary Resolution appoint a replacement security
trustee. While the manager acts as security trustee, it is entitled to the
security trustee's fee.

Amendment
      The issuer trustee, the manager, the security trustee and the Class A-1
note trustee, may alter, add to or revoke any provision of the security trust
deed, subject to the limitations described below, if the alteration, addition
or revocation:

    .   in the opinion of the security trustee is made to correct a manifest
        error or is of a formal, technical or administrative nature only;

    .   in the opinion of the security trustee, or of a lawyer instructed by
        the issuer trustee, is necessary or expedient to comply with the
        provisions of any law or regulation or with the requirements of any
        statutory authority;

    .   in the opinion of the security trustee is appropriate or expedient
        as a consequence of an alteration to any law or regulation or
        altered requirements of the government of any jurisdiction or any
        minister, department, commission, office, instrumentality, agency,
        board, authority or organ of such a government or any person or
        delegate deriving authority from any of them, including, without
        limitation, an alteration, addition or revocation which is
        appropriate or expedient as a result of an alteration to Australia's
        tax laws or any ruling by the Australian Commissioner or Deputy
        Commissioner of Taxation or any governmental announcement or
        statement, which has or may have the effect of altering the manner
        or basis of taxation of trusts generally or of trusts similar to the
        trust under the security trust deed;

    .   in the opinion of the security trustee is otherwise desirable for
        any reason.

      If any alteration, addition or revocation referred to in the last bullet
point above, in the opinion of the Class A-1 note trustee, affects the Class A-
1 noteholders only or in a manner differently to Secured Creditors generally,
alters the terms of the Class A-1 notes or is materially prejudicial to the
interests of Class A-1 noteholders, the alteration, addition or revocation will
not be effective unless the consent of Class A-1 noteholders owning 75% of the
aggregate outstanding principal balance of the Class A-1 notes is obtained.

      Any alteration, addition or revocation must be notified to the rating
agencies 5 Business Days in advance.

      The Class A-1 note trustee will be entitled to assume that any proposed
alteration, addition or revocation will not be materially prejudicial to the
interests of the Class A-1 noteholders if each of the rating agencies confirms
in writing that if the alteration, addition or revocation is effected this will
not lead to a reduction, qualification or withdrawal of the then rating given
to the Class A-1 notes by the rating agency.

      If any alteration, addition or revocation referred to above purports to
effect a Payment Modification it will not be effective as against a given Class
A-1 noteholder unless consented to by that Class A-1 noteholder.

Servicing of the Housing Loans

Appointment and Obligations of Servicer
     Commonwealth Bank is appointed as servicer of the housing loans on the
terms set out in the series supplement.

     The servicer is required to administer the housing loans in the following
manner:

    .   in accordance with the series supplement;

    .   in accordance with the servicer's procedures manual and policies as
        they apply to those housing loans 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

    .   to the extent not covered by the preceding paragraphs, in accordance
        with the standards and practices of a prudent lender in the business
        of originating and servicing retail home loans.

     The servicer's actions in servicing the housing loans are binding on the
issuer trustee, whether or not such actions are in accordance with the
servicer's obligations. The servicer is entitled to delegate its duties under
the series supplement however it must not delegate a material part of its
duties. The servicer at all times remains liable for the acts or omissions of
any delegate to the extent that those acts or omissions constitute a breach of
the servicer's obligations.

Powers
     The function of servicing the housing loans is vested in the servicer and
it is entitled to service the housing loans to the exclusion of the issuer
trustee. The servicer has a number of express powers, which include the power:

    .   to release a borrower from any amount owing where the servicer has
        written-off or determined to write-off that amount or where it is
        required to do so by a court or other binding authority;

    .   subject to the preceding paragraph, to waive any right in respect of
        the housing loans and their securities, except that the servicer may
        not increase the term of a housing loan beyond 30 years from its
        settlement date unless required to do so by a court or other binding
        authority;

                                      118
<PAGE>

    .   to release or substitute any security for a housing loan in
        accordance with the relevant mortgage insurance policy;

    .   to consent to subsequent securities over a mortgaged property for a
        housing loan, provided that the security for the housing loan
        retains priority over any subsequent security for at least the
        principal amount and accrued and unpaid interest on the housing loan
        plus any extra amount determined in accordance with the servicer's
        procedures manual and policies;

    .   to institute litigation to recover amounts owing under a housing
        loan, but it is not required to do so if, based on advice from
        internal or external legal counsel, it believes that the housing
        loan is unenforceable or such proceedings would be uneconomical;

    .   to take other enforcement action in relation to a housing loan as it
        determines should be taken; and

    .   to compromise, compound or settle any claim in respect of a mortgage
        insurance policy or a general insurance policy in relation to a
        housing loan or a mortgaged property for a housing loan.

Undertakings by the Servicer
      The servicer has undertaken, among other things, the following:

    .   upon being directed by the issuer trustee following a Perfection of
        Title Event, it will promptly take all action required or permitted
        by law to assist the issuer trustee to perfect the issuer trustee's
        legal title to the housing loans and related securities;

    .   to make reasonable efforts to collect all moneys due under the
        housing loans and related securities and, to the extent consistent
        with the series supplement, to follow such normal collection
        procedures as it deems necessary and advisable;

    .   to comply with its material obligations under each mortgage
        insurance policy;

    .   it will notify the issuer trustee if it becomes actually aware of
        the occurrence of any Servicer Default or Perfection of Title Event;

    .   it will obtain and maintain all authorizations, filings and
        registrations necessary to properly service the housing loans; and

    .   subject to the provisions of the Australian Privacy Act and its duty
        of confidentiality to its clients, it will promptly make available
        to the manager, the auditor of the trust and the issuer trustee any
        books, reports or other oral or written information and supporting
        evidence of which the servicer is aware that they reasonably request
        with respect to the trust or the assets of the trust or with respect
        to all matters in respect of the activities of the servicer to which
        the series supplement relates.


                                      119
<PAGE>

Administer Interest Rates
      The servicer must set the interest rates to be charged on the variable
rate housing loans and the monthly instalment to be paid in relation to each
housing loan. Subject to the next paragraph, while Commonwealth Bank is the
servicer, it must charge the same interest rates on the variable rate housing
loans in the pool as it does for housing loans of the same product type which
have not been assigned to the issuer trustee.

      If the basis swap has terminated while any notes or redraw bonds are
outstanding then, unless the issuer trustee has entered into a replacement
basis swap or other arrangements which the rating agencies have confirmed will
not result in a reduction, qualification or withdrawal of the credit ratings
assigned to the notes or redraw bonds, the servicer must ensure that the
weighted average of the variable rates charged on the housing loans is
sufficient, subject to applicable laws, including the Consumer Credit Code,
assuming that all relevant parties comply with their obligations under the
housing loans and the transaction documents, to ensure that issuer trustee has
sufficient funds to comply with its obligations under the transaction documents
as they fall due.

Collections
      The servicer will receive collections on the housing loans from
borrowers. The servicer must deposit any collections into the collections
account within 5 Business Days following its receipt. However if the
collections account is permitted to be maintained with the servicer and:

    .   the servicer has short term credit ratings of A-1+ from Standard &
        Poor's, P-1 from Moody's and F1+ from Fitch IBCA or, where the
        seller is the servicer and the servicer is a bank, F1 from Fitch
        IBCA it may retain collections until 10:00 am on the day which is 2
        Business Days before the distribution date following the end of the
        relevant collection period;

    .   the servicer has short term credit ratings of A-1 from Standard &
        Poor's and P-1 from Moody's, it may retain collections until 10.00
        am on the Business Day which is the earlier of 30 days from receipt
        and 2 Business Days before the distribution date following the end
        of the relevant collection period. However, while the sum of all
        collections held by the servicer and the value of any Authorized
        Short-Term Investments which are with, or issued by, a bank or
        financial institution which has a short-term credit rating of A-1
        from Standard & Poor's, exceeds 20% of the aggregate of the Stated
        Amounts of the notes and redraw bonds, the servicer will only be
        entitled to retain any additional collections received for 2
        Business Days following receipt; and

    .   the servicer has no credit ratings or has short term credit ratings
        of lower than A-1 from Standard & Poor's, lower than P-1 from
        Moody's or lower than F1+ from Fitch IBCA or, where the seller is
        the servicer and the servicer is a bank, F1 from Fitch IBCA, it may
        retain collections for 2 Business Days following receipt.

      After the applicable period referred to above, the servicer must deposit
the collections into the collections account.

                                      120
<PAGE>

      If collections are retained by the servicer in accordance with the first
two paragraphs above, the servicer must when depositing the collections into
the collections account also deposit interest on the collections retained equal
to the interest that would have been earned on the collections if they had been
deposited in the collections account within 5 Business Days of their receipt by
the servicer.

Servicing Compensation and Expenses
      The servicer is entitled to a quarterly fee based on [the aggregate
outstanding principal balance of the housing loans on the first day of each
collection period], payable in arrears on the following distribution date.

      The servicer's fee may be varied by agreement between the issuer trustee,
the manager and the servicer provided that the rating agencies are notified and
the servicer's fee is not varied if it would cause a reduction, qualification
or withdrawal in the credit rating of a note or redraw bond.

      The servicer must pay from its own funds all expenses incurred in
connection with servicing the housing loans except for expenses in connection
with 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, which amounts are recoverable from the assets
of the trust.

Liability of the Servicer
      The servicer will not be liable for any loss incurred by any noteholder,
any redraw bondholder, any creditor of the trust or any other person except to
the extent that such loss is caused by a breach by the servicer or any delegate
of the servicer of the series supplement or any fraud, negligence or wilful
default by the servicer. In addition, the servicer will not be liable for any
loss in respect of a default in relation to a housing loan in excess of the
amount outstanding under the housing loan at the time of default less any
amounts that the issuer trustee has received or is entitled to receive under a
mortgage insurance policy in relation to that housing loan.

Removal, Resignation and Replacement of the Servicer
      If the issuer trustee has determined that the performance by the servicer
of its obligations under the series supplement is no longer lawful and there is
no reasonable action that the servicer can take to remedy this, or a Servicer
Default is subsisting, the issuer trustee must by notice to the servicer
immediately terminate the rights and obligations of the servicer and appoint
another bank or appropriately qualified organization to act in its place.

A Servicer Default occurs if:

    .  the servicer fails to remit any collections or other amounts received
       within the time periods specified in the series supplement and that
       failure is not remedied within 5 Business Days, or such longer period
       as the issuer trustee may agree, of notice of that failure given by
       the manager or the issuer trustee;

                                      121
<PAGE>

    .  the servicer fails to prepare and transmit the information required
       by the manager by the date specified in the series supplement and
       that failure is not remedied within 20 Business Days, or such longer
       period as the issuer trustee may agree, of notice of that failure
       given by the manager or the issuer trustee and has or will have an
       Adverse Effect as reasonably determined by the issuer trustee;

    .  a representation, warranty or certification made by the servicer in
       a transaction document or in any certificate delivered pursuant to a
       transaction document proves incorrect when made and has or will have
       an Adverse Effect as reasonably determined by the issuer trustee and
       is not remedied within 60 Business Days after receipt by the
       servicer of notice from the issuer trustee requiring remedy;

    .  an Insolvency Event occurs in relation to the servicer;

    .  if the servicer is the seller and is acting as custodian, it fails
       to deliver all the mortgage documents to the issuer trustee
       following a document transfer event in accordance with the series
       supplement and does not deliver to the issuer trustee the
       outstanding documents within 20 Business Days of receipt of a notice
       from the issuer trustee specifying the outstanding documents;

    .  the servicer fails to maintain the required threshold rate on the
       housing loans following termination of the basis swap and that
       failure is not remedied within 20 Business Days of its occurrence;
       or

    .  the servicer breaches its other obligations under a transaction
       document and that breach has or will have an Adverse Effect as
       reasonably determined by the issuer trustee and:

      .  the breach is not remedied within 20 Business Days after receipt
         of notice from the trustee or manager requiring its remedy; and

      .  the servicer has not paid satisfactory compensation to the issuer
         trustee.

      The servicer may voluntarily retire if it gives the issuer trustee 3
months' notice in writing or such lesser period as the servicer and the issuer
trustee agree. Upon retirement the servicer may appoint in writing any other
corporation approved by the issuer trustee. If the servicer does not propose a
replacement by one month prior to its proposed retirement, the issuer trustee
may appoint a replacement.

      Pending the appointment of a new servicer, the issuer trustee will act as
servicer and will be entitled to the servicer's fee.

      The appointment of a substitute servicer is subject to confirmation from
the rating agencies that the appointment will not cause a reduction,
qualification or withdrawal in the credit ratings of the notes or redraw bonds.

Seller Deposit
      If the seller has a short-term deposit credit rating by Moody's of less
than P-1 or such other rating as is agreed between the issuer trustee, the
seller, the manager and Moody's or has a long term deposit credit rating
assigned by Standard & Poor's or Fitch IBCA of less than BBB or such other
rating as is agreed between the issuer trustee, the seller, the manager and
Standard & Poor's or Fitch IBCA, as the case may be, it must in respect of set-
off risk in relation to the trust:

    .  deposit or maintain in the collections account on each distribution
       date, after giving effect to the payments to be made on that
       distribution date, an amount being the higher of the amount specified
       by Standard & Poor's from time to time or determined in accordance
       with the series supplement or otherwise agreed by Moody's or Fitch
       IBCA. This deposit may be utilized by the issuer trustee to meet any
       liabilities of the seller to the issuer trustee in relation to the
       exercise of set-off rights in relation to the housing loans, which
       the seller has not met within 20 Business Days of notice from the
       issuer trustee or the manager; or

    .  enter into such other arrangement from time to time agreed between
       the seller and the relevant rating agency so as to ensure that rating
       agency does not reduce, qualify or withdraw any credit rating
       assigned by it to the notes or redraw bonds.

Custody of the Housing Loan Documents

Document Custody
      The seller will retain all documents relating to the housing loans, their
securities and, where applicable, the certificates of title to property subject
to those securities, until a transfer of the housing loan documents to the
issuer trustee as described below.

      The seller's duties and responsibilities as custodian include:

    .  holding the housing loan documents in accordance with its standard
       safe keeping practices and in the same manner and to the same extent
       as it holds its own documents;

    .  marking and segregating the security packages containing the housing
       loan documents in a manner to enable easy identification by the
       issuer trustee when the issuer trustee is at the premises where the
       housing loan documents are located with a letter provided by the
       seller explaining how those security packages are marked or
       segregated;

    .  maintaining reports on movements of the housing loan documents;

    .  providing to the issuer trustee prior to the closing date and on each
       distribution date computer diskettes containing certain information
       in relation to the storage of the housing loan documents and the
       borrower, mortgaged property and housing loan account number in
       relation to each housing loan; and

    .  curing any deficiencies noted by the auditor in a document custody
       auditor report.

                                      123
<PAGE>

Audit
      The seller will be audited by an independent auditor on an annual basis
in relation to its compliance with its obligations as custodian of the housing
loan documents and will be instructed to provide a document custody audit
report. The document custody audit report will grade the seller from "A" (good)
to "D" (adverse). If the seller receives an adverse document custody audit
report, the issuer trustee must instruct the auditor to conduct a further
document custody audit report.

Transfer of Housing Loan Documents
      If:

    .  an adverse document custody audit report is provided by the auditor
       and a further report, conducted no earlier than one month nor later
       than two months after the first report, is also an adverse report;

    .  the issuer trustee replaces Commonwealth Bank as the servicer when
       entitled to do so; or

    .  the long term debt rating of the seller is downgraded below BBB by
       Standard & Poor's or Fitch IBCA or Baa2 by Moody's or such other
       rating as is agreed between the manager, the servicer and the
       relevant rating agency,

the seller, upon notice from the issuer trustee, must transfer custody of the
housing loan documents to the issuer trustee. This obligation will be satisfied
if the seller delivers the housing loan documents in relation to 90% by number
of the housing loans within 5 Business Days of that notice and the balance
within 10 Business Days of that notice.

      In addition, if:

    .  the issuer trustee declares that a Perfection of Title Event has
       occurred; or

    .  a Servicer Default occurs as a result of a breach of the servicer's
       obligations which has or will have an Adverse Effect which is not
       remedied within the required period,

the seller must, immediately following notice from the issuer trustee, transfer
custody of the mortgage documents to the issuer trustee.

      The seller is not required to deliver housing loan documents that are
lodged with a governmental agency or lost but must provide a list of these to
the issuer trustee and deliver them upon receipt or take steps to replace them,
as applicable.

Reappointment of Seller as Custodian
      The issuer trustee may, following a transfer of housing loan documents,
reappoint the seller as custodian of the housing loan documents provided that
the rating agencies confirm that this will not cause a reduction, qualification
or withdrawal in the credit rating of any note or redraw bond.

                                      124
<PAGE>

Clean-Up and Extinguishment
      The seller will have certain rights to extinguish the issuer trustee's
interest in the housing loans and their related securities, mortgage insurance
policies and other rights, or to otherwise regain the benefit of the housing
loans and their related securities, mortgage insurance policies and other
rights, if:

    .  the date on which the total principal outstanding on the housing
       loans is less than 10% of the total principal outstanding on the
       housing loans on [     ] has occurred or is expected to occur on or
       before the next distribution date; or

    .  both of the following events occur:

      .  the next distribution date is the distribution date falling in
         [      ] or the issuer trustee will be entitled to redeem the
         notes and redraw bonds because of the imposition of a withholding
         or other tax; and

      .  the seller has previously notified the manager that the Australian
         Prudential Regulation Authority will permit the seller to exercise
         its rights to extinguish the issuer trustee's interest in the
         housing loans notwithstanding that the total principal outstanding
         on the housing loans is greater than 10% of the total principal
         outstanding on the housing loans on [     ].

The seller may only exercise those rights by paying to the issuer trustee on a
distribution date the amount determined by the manager to be the aggregate of
the Fair Market Value as at the last day of the immediately preceding accrual
period of the housing loans. If any notes or redraw bonds are outstanding the
seller will not be able to exercise those rights unless the amount to be paid
by the seller to the issuer trustee will be sufficient to redeem the notes and
redraw bonds in full. In addition, the seller may not exercise those rights
where the issuer trustee's right to redeem the notes and redraw bonds arises
from the imposition of a tax or duty applicable only to the Class A-1 notes and
the holders of 75% of the aggregate Stated Amount of the Class A-1 notes have
elected that they do not require the issuer trustee to redeem the Class A-1
notes.

                                  The Servicer

Servicing of Housing Loans
      Under the series supplement, Commonwealth Bank will be appointed as the
initial servicer of the housing loans. The day to day servicing of the housing
loans will be performed by the servicer at Commonwealth Bank's loan processing
centers, presently located in Sydney, Melbourne, Brisbane, Perth and Adelaide,
and at Commonwealth Bank's retail branches and telephone banking and marketing
centers. Servicing procedures undertaken by loan processing centres include
partial loan security discharges, loan security substitutions, consents for
subsequent mortgages and arrears management. Customer enquiries are dealt with
by the retail branches and telephone banking and marketing centers. For a
further description of the duties of the servicer, see "Description of the
Transaction Documents--The Servicing of the Housing Loans."

                                      125
<PAGE>

Collection and Enforcement Procedures
      Pursuant to the terms of the housing loans, borrowers must make the
minimum repayment due under the terms and conditions of the housing loans, on
or before each monthly installment due date. A borrower may elect to make his
or her repayments weekly or fortnightly so long as the equivalent of the
minimum monthly repayment is received on or before the monthly installment due
date. Borrowers often select repayment dates to coincide with receipt of their
salary or other income. In addition to payment to a retail branch by cash or
cheque, housing loan repayments may be made by direct debit to a nominated bank
account or direct credit from the borrower's salary by their employer. At
present over 90% of scheduled repayments on the housing loans are made by way
of direct debits to a nominated bank account.

      Commonwealth Bank credits repayments to an individual housing loan on the
date of its receipt. Interest is accrued daily on the balance outstanding after
close of business and charged monthly to each relevant housing loan account.

      A housing loan is subject to action in relation to arrears of payment
whenever the monthly repayment is not paid by the monthly installment due date.
However, under the terms of the housing loans, borrowers may prepay amounts
which are additional to their required monthly repayments to build up a "credit
buffer," being the difference between the total amount paid by them and the
total of the monthly repayments required to be made by them. If a borrower
subsequently fails to make some or all of a required monthly repayment, the
servicing system will apply the amount not paid against the credit buffer until
the total amount of missed payments exceeds the credit buffer. The housing loan
will be considered to be arrears only in relation to that excess. See
"Commonwealth Bank Residential Loan Program--Payment Holidays."

      Commonwealth Bank's automated collections system identifies all housing
loan accounts which are in arrears and produces lists of those housing loans.
The collection system allocates overdue loans to designated collection officers
within Commonwealth Bank who take action in relation to the arrears.

      Actions taken by Commonwealth Bank in relation to delinquent accounts
will vary depending on a number of elements, including the following and, if
applicable, with the input of the mortgage insurer:

    .  arrears history;

    .  equity in the property; and

    .  arrangements made with the borrower to meet overdue payments.

If satisfactory arrangements cannot be made to rectify a delinquent housing
loan, legal notices are issued and recovery action is initiated by Commonwealth
Bank. This includes, if Commonwealth Bank obtains possession of the mortgaged
property, ensuring that the mortgaged property supporting the housing loan
still has adequate general home owner's insurance and that the upkeep of the
mortgaged property is maintained. Recovery action is

                                      126
<PAGE>

arranged by experienced collections staff in conjunction with internal or
external legal advisers. A number of sources of recovery are pursued including
the following:

    .  voluntary sale by the mortgagor;

    .  guarantees;

    .  government assistance schemes;

    .  mortgagee sale; and

    .  claims on mortgage insurance.

It should be noted that Commonwealth Bank reports all actions that it takes on
overdue housing loans to the relevant mortgage insurer where required in
accordance with the terms of the mortgage insurance policies.

Collection and Enforcement Process
      When a housing loan is more than 7 days delinquent a call to the borrower
is made to seek full and immediate clearance of all arrears. In the absence of
successful call contact arrears follow-up letters to the borrower are sent. If
the housing loans have a direct debit payment arrangement, a sweep of the
nominated account is made to rectify the arrears.

      When a housing loan reaches 60 days delinquent, a default notice is sent
advising the borrower that if the matter is not rectified within a period of 30
days, Commonwealth Bank is entitled to commence enforcement proceedings without
further notice. Normally a further notice will be issued to a borrower on an
account which is 90 days delinquent advising the borrower that failure to
comply within 30 days will result in Commonwealth Bank exercising its power of
sale. At 120 days delinquent, a letter of demand and notice to vacate is issued
to the borrower, followed by a statement of claim at 150 days delinquent. Once
a statement of claim is served, Commonwealth Bank can then enter judgement in
the Supreme Court. The borrower is given up to 40 days to file a notice of
appearance and defense and, failing this, Commonwealth Bank will then have
judgment entered and will apply for a writ of possession whereby the sheriff
will set an eviction date. Appraisals and valuations are ordered and a reserve
price is set for sale by way of auction or private treaty. These time frames
assume that the borrower has either taken no action or has not honored any
commitments made in relation to the delinquency to the satisfaction of the
Commonwealth Bank and the mortgage insurer.

      It should also be noted that the mortgagee's ability to exercise its
power of sale on the mortgaged property is dependent upon the statutory
restrictions of the relevant state or territory as to notice requirements. In
addition, there may be factors outside the control of the mortgagee such as
whether the mortgagor contests the sale and the market conditions at the time
of sale. These issues may affect the length of time between the decision of the
mortgagee to exercise its power of sale and final completion of the sale.

      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.

      There can be no assurance that the delinquency experience with respect to
the housing loans comprising the housing loan pool will correspond to the
delinquency experience of the servicer's securitized portfolios set forth in
the foregoing tables. The statistics shown in the preceding tables represent
the delinquency experience for the securitized portfolios for each of the years
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. In addition, the foregoing statistics
include housing loans with a variety of payment and other characteristics that
may not correspond to those of the housing loans comprising the housing loan
pool. Moreover, if the residential real estate market should experience an
overall decline in property values such that the principal balances of the
housing loans comprising the securitized portfolios become equal to or greater
than the value of the related mortgaged properties, the actual rates of
delinquencies could be significantly higher than those previously experienced
by the servicer. In addition, adverse economic conditions, which may or may not
affect real property values, may affect the timely payment by borrowers of
scheduled payments of principal and interest on the housing loans and,
accordingly, the rates of delinquencies, bankruptcies and losses with respect
to the securitized portfolios. You should note that Australia experienced a
period of relatively low and stable interest rates during the period covered in
the preceding tables. If interest rates were to rise, it is likely that the
rate of delinquencies and losses would increase.

                      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 notes
under the stated assumptions and is not a prediction of the prepayment rate
that might actually be experienced.

General
      The rate of principal payments and aggregate amount of distributions on
the notes and the yield to maturity of the notes will relate 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 the seller. Subject, in the case of fixed rate housing loans, to the payment
of applicable fees, the housing loans may be prepaid by the mortgagors at any
time.

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 early distributions of principal
amounts on the notes. Prepayments of principal may occur in the following
situations:

    .  refinancing by mortgagors with other financiers;

    .  receipt by the issuer trustee of enforcement proceeds due to a
       mortgagor having defaulted on its housing loan;

    .  receipt by the issuer trustee of insurance proceeds in relation to a
       claim under a mortgage insurance policy in respect of a housing loan;

    .  repurchase by the seller as a result of a breach by it of certain
       representations, if any;

    .  repurchase by the seller upon a further advance being made which
       exceeds the then scheduled balance of the housing loan by more than
       one scheduled monthly installment;

    .  repurchase of the housing loans as a result of an optional
       termination or a redemption for taxation or other reasons;

    .  receipt of proceeds of enforcement of the security trust deed prior
       to the final maturity date of the notes; and

    .  receipt of proceeds of the sale of housing loans if the trust is
       terminated while notes are outstanding, for example, if required by
       law, and the housing loans are then either

      .  repurchased by Commonwealth Bank under its right of first refusal;
         or

      .  sold to a third party.

                                      131
<PAGE>

      The prepayment amounts described above are reduced by:

    .  principal draws; and

    .  repayment of redraw advances.

      Since the rate of payment of principal of the housing loans cannot be
predicted and will depend on future events and a variety of factors, no
assurance can be given to you as to this rate of payment or the rate of
principal prepayments. The extent to which the yield to maturity of any note
may vary from the anticipated yield will depend upon the following factors:

    .  the degree to which a note is purchased at a discount or premium; and

    .  the degree to which the timing of payments on the note is sensitive
       to prepayments, liquidations and purchases of the housing loans.

      A wide variety of factors, including economic conditions, the
availability of alternative financing and homeowner mobility may affect the
trust's prepayment experience with respect to the housing loans. In particular,
under Australian law, unlike the law of the United States, interest on loans
used to purchase a principal place of residence is not ordinarily deductible
for taxation purposes.

Weighted Average Lives
      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 the note is reduced to zero.

      Usually, greater than anticipated principal prepayments will increase the
yield on notes purchased at a discount and will decrease the yield on notes
purchased at a premium. The effect on your yield due to principal prepayments
occurring at a rate that is faster or slower than the rate you anticipated will
not be entirely offset by a subsequent similar reduction or increase,
respectively, in the rate of principal payments. The amount and timing of
delinquencies and defaults on the housing loans and the recoveries, if any, on
defaulted housing loans and foreclosed properties will also affect the weighted
average life of the notes.

      The following tables are based on a constant prepayment rate model.
Constant prepayment rate 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. Constant prepayment rate 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 in your pool. Neither of the seller nor the manager believes that
any existing statistics of which it is aware provide a reliable basis for
noteholders to predict the amount or timing of receipt of housing loan
prepayments.

      The following tables are based upon the assumptions in the following
paragraph, and not upon the actual characteristics of the housing loans. Any
discrepancies between

                                      132
<PAGE>

characteristics of the actual housing loans and the assumed housing loans may
have an effect upon the percentages of the principal balances outstanding and
weighted average lives of the notes set forth in the tables. Furthermore, since
these discrepancies exist, principal payments on the notes may be made earlier
or later than the tables indicate.

      For the purpose of the following tables, it is assumed that:

    .  the housing loan pool consists of fully-amortizing housing loans;

    .  the cut-off date is the close of business on [      ];

    .  closing date for the notes is [      ];

    .  payments on the notes are made on the quarterly payment date,
       regardless of the day on which payment actually occurs, commencing in
       [      ] 2000 and are made in accordance with the priorities
       described in this prospectus;

    .  the housing loans' prepayment rates are equal to the respective
       percentages of constant prepayment rate indicated in the tables;

    .  the scheduled monthly payments of principal and interest on the
       housing loans will be timely delivered on the first day of each
       month, [except in the month of [      ], in which case, payments are
       calculated based on a rateable share of one month's collections,]
       assuming a start date of the close of business [      ], 2000, with
       no defaults;

    .  there are no redraws, substitutions or payment holidays with respect
       to the housing loans;

    .  there are no releases from the liquidity reserve;

    .  all prepayments are prepayments in full received on the last day of
       each month and include 30 days' interest on the prepayment;

    .  principal collections are distributed according to the rules of
       distribution set forth in this prospectus;

    .  all payments under the swaps are made as scheduled;

    .  the manager does not direct the issuer trustee to exercise its right
       of optional redemption of the notes, except with respect to the line
       titled "Weighted Average Life--To Call (Years)"; and

    .  the exchange rate is US$ [0.6377]=A$1.00

      It is not likely that the housing loans will pay at any assumed constant
prepayment rate to maturity or that all housing loans will prepay at the same
rate. In addition, the diverse remaining terms to maturity of the housing loans
could produce slower or faster distributions of principal than indicated in the
tables at the assumed constant prepayment rate 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 in
this section. You are urged to make your investment decisions on a basis that
includes your

determination as to anticipated prepayment rates under a variety of the
assumptions discussed in this prospectus as well as other relevant assumptions.

      In the following tables, the percentages have been rounded to the nearest
whole number and the weighted average life of a class of notes is determined by
the following three step process:

    .  multiplying the amount of each payment of principal thereof by the
       number of years from the date of issuance to the related payment
       date,

    .  summing the results, and

    .  dividing the sum by the aggregate distributions of principal referred
       to in the first clause above and rounding to two decimal places.

                       Legal Aspects of the Housing Loans

      The following discussion is a summary of the material legal aspects of
Australian retail housing loans and mortgages. It is not an exhaustive analysis
of the relevant law. Some of the legal aspects are governed by the law of the
applicable State or Territory. Laws may differ between States and Territories.
The summary does not reflect the laws of any particular jurisdiction or cover
all relevant laws of all jurisdictions in which a mortgaged property may be
situated, although it reflects the material aspects of the laws of New South
Wales (except where it expressly provides otherwise), without referring to any
specific legislation of that State.

General
      There are two parties to a mortgage. The first party is the mortgagor,
who is either the borrower or, where the relevant loan is guaranteed and the
guarantee is secured by a mortgage, the guarantor. The mortgagor grants the
mortgage over their property. The second party is the mortgagee, who is the
lender. Each housing loan will be secured by a mortgage which has a first
ranking priority in respect of the mortgaged property over all other mortgages
granted by the relevant borrower or guarantor and over all unsecured creditors
of the borrower or guarantor, except in respect of certain statutory rights
such as some rates and taxes, which are granted statutory priority. Each
borrower under the housing loans is prohibited under its loan documents from
creating another mortgage or other security interest over the relevant
mortgaged property without the consent of Commonwealth Bank.

Nature of Housing Loans as Security
      There are a number of different forms of title to land in Australia. The
most common form of title in Australia is "Torrens title." Each housing loan in
the pool will be secured by Torrens title land.

      "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, registered easements and other
dealings to which it is subject. The certificate is conclusive evidence, except
in limited circumstances, such as fraud, of the matters stated in it.

                                      136
<PAGE>

      Some Torrens title property securing housing loans and thus comprised in
the mortgaged property, will be "strata title," "stratum title" or "residential
Crown leasehold."

Strata title and Stratum title
      "Strata title" and "stratum title" were developed to enable 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 both strata title and stratum title, each
proprietor has title to, and may freely dispose of, their apartment unit.
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 a "body corporate" or a "service company" for the
benefit of the individual proprietors. All proprietors are members of the body
corporate or service company, which is vested with the control, management and
administration of the common property and the strata scheme generally, for the
benefit of the proprietors. In general, the body corporate or service company
will have a charge (either registered or created by statute) over the units of
its members to secure fees payable by the members. This charge will take
priority over the mortgage securing the housing loan.

      Only Torrens title land can be the subject of strata or stratum title in
this way, and so the provisions referred to in this section in relation to
Torrens title apply to the title in an apartment unit held by a strata or
stratum proprietor.

Residential Crown Leasehold
      All land in the Australian Capital Territory is owned by the Commonwealth
of Australia and is subject to a leasehold system of land title known as Crown
leasehold. Mortgaged residential property in that jurisdiction comprises a
Crown lease and developments on the land are subject to the terms of that
lease. Any such lease:

    .  cannot have a term exceeding 99 years, although the term can be
       extended in effect under a straightforward administrative process,
       whereby the existing lease is surrendered and a new lease is granted
       for a term not exceeding 99 years, unless the Commonwealth or
       Australian Capital Territory Government considers that the land is
       required for a public purpose; and

    .  is subject to a nominal rent of 5 cents per annum on demand.

      As with other Torrens title land, the mortgagor's leasehold interest in
the land is entered in a central register and, subject to some exceptions, the
mortgagor may deal with its residential 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.

      Leasehold property may become subject to native title claims. Native
title has only quite recently been recognized by Australian courts. Native
title to particular property is based on the traditional laws and customs of
indigenous Australians and is not necessarily

                                      137
<PAGE>

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 would 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.

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 some 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 both
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 or registered title. However, registration does not transfer title in
the property and 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 creditor or proposed creditor 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 his or her debt, a discharge executed by
the mortgagee is lodged with the relevant registrar by the mortgagor or the
mortgagee and the mortgage is noted as having been released.

Commonwealth Bank as Mortgagee
      Commonwealth Bank is, and until a Perfection of Title Event occurs,
intends to remain, the registered mortgagee of all the mortgages. The borrowers
will not be aware of the equitable assignment of the housing loans and
mortgages to the issuer trustee.

      Prior to any Perfection of Title Event, Commonwealth Bank, as servicer,
will undertake any necessary enforcement action with respect to defaulted
housing loans and

                                      138
<PAGE>

mortgages. Following a Perfection of Title Event, the issuer trustee is
entitled, under an irrevocable power of attorney granted to it by Commonwealth
Bank, to be registered as mortgagee of the mortgages. Until that registration
is achieved, the issuer trustee or the manager is entitled to lodge caveats on
the register publicly to notify its interest in the mortgages (and must do so
if it has not commenced to take all necessary steps to perfect its legal title
within 30 Business Days of its declaration that a Perfection of Title Event has
occurred).

Enforcement of Registered Mortgages
      Subject to the discussion in this section, if a borrower defaults under a
housing loan, the loan documents provide that all moneys under the housing 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:

    .  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.

    .  The mortgagee may, in limited circumstances, lease the property to
       third parties.

    .  The mortgagee may foreclose on the property. Under foreclosure
       procedures, the mortgagee extinguishes 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.

    .  The mortgagee may appoint a receiver to deal with income from the
       property or exercise other rights delegated to the receiver by the
       mortgagee. A receiver is the agent of the mortgagor and so, unlike
       when the mortgagee enters possession of property, in theory the
       mortgagee is not liable for the receiver's acts or as occupier of the
       property. In practice, however, the receiver will require indemnities
       from the mortgagee that appoints it.

    .  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 in registered mortgages under
       the relevant Torrens title legislation. The Torrens title legislation
       prescribes certain 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 the
       absolute owner of the property.


                                      139
<PAGE>

      A mortgagee's ability to call in all amounts under a housing loan or
enforce a mortgage which is subject to the Consumer Credit Code 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 payments if the court determines that the
relevant default interest rate is a penalty. A default interest rate will not
be a penalty if the amount payable on default is a genuine pre-estimate of the
loss that the lender will suffer as a result of the default. The Consumer
Credit Code 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, where a company is
being wound up, a loan is voidable if it is an unfair loan. A loan will only be
unfair if the interest or charges on the loan were extortionate when the loan
was made or have become extortionate because of a variation.

      The Consumer Credit Code requires that certain fees or charges to be
levied by the lender must be provided for in the contract, otherwise they
cannot be levied. The regulations under the Consumer Credit Code may also from
time to time prohibit certain fees and charges. There are none currently so
prohibited. The Consumer Credit Code also requires that establishment fees,
early termination fees and prepayment fees must not be unconscionable otherwise
they may be reduced or set aside.

Bankruptcy and Insolvency
      The insolvency of a natural person is governed by the provisions of the
Bankruptcy Act 1966 of Australia, 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, or
file a claim, in the bankruptcy proceeding as an unsecured creditor in a number
of circumstances, 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:

    .  the disposition was made to defraud creditors; or

    .  the disposition was made by an insolvent debtor within a prescribed
       period and that disposition had the effect of giving a creditor a
       preference, priority or advantage over other creditors.

      The insolvency of a company is governed by the Corporations Law of the
relevant Australian jurisdiction. Again, secured creditors generally stand
outside the insolvency.

                                      140
<PAGE>

However, a liquidator may avoid a housing loan or a mortgage which is voidable
under the Corporations Law because it is an uncommercial transaction, or an
unfair preference to a creditor and that transaction occurs:

    .  when the company is insolvent, or an act is done, or an omission is
       made, to give effect to the transaction when the company is
       insolvent, or the company becomes insolvent because of, or because of
       matters including, the entering into of the transaction or the doing
       of an act, or the making of an omission, to give effect to the
       transaction; and

    .  within a prescribed period prior to the commencement of the winding
       up of the company.

      A liquidator may also avoid a housing loan if it is an unfair loan being
a loan in relation to which an extortionate interest rate or charges are
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 takes 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. To the extent that the issuer
trustee or a receiver appointed on its behalf incurs any such liabilities, it
will be entitled to be indemnified out of the assets of the trust.

Insolvency Considerations
      The current transaction is intended to mitigate insolvency risk. For
example, the equitable assignment of the housing loans by Commonwealth Bank to
the issuer trustee should ensure that the housing loans are not assets
available to the liquidator or creditors of Commonwealth Bank in the event of
the insolvency of Commonwealth Bank. 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 the insolvency of the
issuer trustee.

                                      141
<PAGE>

      If any Insolvency Event occurs with respect to the issuer trustee in its
capacity as trustee of the trust, the security trust deed may be enforced by
the security trustee at the direction of the Voting Secured Creditors. See
"Description of the Transaction Documents--Security Trust Deed--Enforcement of
the Charge." 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
or is a creditor of the trust with a right of subrogation to the issuer
trustee's lien over the assets of the trust. The proceeds of enforcement of the
security trust deed are to be applied by the security trustee as set out in
"Description of the Transaction Documents--The Security Trust Deed--Priorities
under the Security Trust Deed." If the proceeds from enforcement of the
security trust deed are not sufficient to redeem the Class A-1 notes in full,
some or all of the Class A-1 noteholders will incur a loss.

Tax Treatment of Interest on 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 loans and other non-capital expenditures
relating to non-owner occupied properties that generate taxable income are
generally allowable as tax deductions.

Consumer Credit Code
      Under the Consumer Credit Code, a borrower has the right to apply to a
court to do the following, among other things:

    .  vary the terms of a housing loan on the grounds of hardship or that
       it is an unjust contract;

    .  reduce or cancel any interest rate payable on a housing loan if the
       interest rate is changed in a way which is unconscionable;

    .  have certain provisions of a housing loan which are in breach of the
       legislation declared unenforceable;

    .  obtain an order for a civil penalty against the seller, the amount of
       which may be set off against any amount payable by the borrower under
       the applicable housing loan; or

    .  obtain restitution or compensation from the seller in relation to
       breaches of the Consumer Credit Code in relation to a housing loan.

      The issuer trustee will become liable for compliance with the Consumer
Credit Code if it acquires legal title to the housing loans. It will take this
legal title subject to any breaches of the Consumer Credit Code by the seller.
In particular, once the issuer trustee acquires legal title it may become
liable to orders of the type referred to in the last two bullet points listed
above in relation to breaches of the Consumer Credit Code. Any order under the
Consumer Credit Code 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 to
you under the Class A-1

                                      142
<PAGE>

notes. The servicer will indemnify the issuer trustee against any liability
under the Consumer Credit Code in relation to the trust where the events giving
rise to that liability occur before a Perfection of Title Event and against any
such liability where the events giving rise to that liability occur after a
Perfection of Title Event to the extent that they arise from a Servicer Default
or a failure of the servicer to comply with its obligations under any
transaction document.

                    United States Federal Income Tax Matters

Overview
      The following is a summary of all material United States federal income
tax consequences of the purchase, ownership and disposition of the Class A-1
notes by investors who are subject to United States federal income tax. This
summary is based upon current provisions of the Internal Revenue Code of 1986,
as amended, proposed, temporary and final Treasury regulations under the Code,
and published rulings and court decisions, all of which are subject to change,
possibly retroactively, or to a different interpretation at a later date by a
court or by the IRS. The parts of this summary which relate to matters of law
or legal conclusions represent the opinion of Mayer, Brown & Platt, special
United States federal tax counsel for the manager, and are as qualified in this
summary. We have not sought and will not seek any rulings from the IRS about
any of the United States federal income tax consequences we discuss, and we
cannot assure you that the IRS will not take contrary positions.

      Mayer, Brown & Platt has prepared or reviewed the statements under the
heading "United States Federal Income Tax Matters" and is of the opinion that
these statements discuss all material United States federal income tax
consequences to investors generally of the purchase, ownership and disposition
of the Class A-1 notes. However, the following discussion does not discuss and
Mayer, Brown & Platt is unable to opine as to the unique tax consequences of
the purchase, ownership and disposition of the Class A-1 notes by investors
that are given special treatment under the United States federal income tax
laws, including:

    .  banks and thrifts;

    .  insurance companies;

    .  regulated investment companies;

    .  dealers in securities;

    .  investors that will hold the notes as a position in a "straddle" for
       tax purposes or as a part of a "synthetic security," "conversion
       transaction" or other integrated investment comprised of the notes
       and one or more other investments;

    .  foreign investors;

    .  trusts and estates; and

    .  pass-through entities, the equity holders of which are any of the
       foregoing.


                                      143
<PAGE>

      Additionally, the discussion regarding the Class A-1 notes is limited to
the United States federal income tax consequences to the initial investors and
not to a purchaser in the secondary market and is limited to investors who will
hold the Class A-1 notes as "capital assets" within the meaning of Section 1221
of the Code.

      It is suggested that prospective investors consult their own tax advisors
about the United States federal, state, local, foreign and any other tax
consequences to them of the purchase, ownership and disposition of the Class A-
1 notes, including the advisability of making any election discussed under
"Market Discount."

      [The issuer trustee will be reimbursed for any United States federal
income taxes imposed on it in its capacity as trustee of the trust out of the
assets of the trust. Also, based on the representation of the manager that the
trust does not and will not have an office in the United States, and that the
trust is not conducting, and will not conduct any activities in the United
States, other than in connection with its issuance of the Class A-1 notes, in
the opinion of Mayer, Brown & Platt, the issuer trustee will not be subject to
United States federal income tax.]

General
      Mayer, Brown & Platt is of the opinion that you will be required to
report interest income on the Class A-1 notes you hold in accord with your
method of accounting.

Sale of Notes
      Mayer, Brown & Platt is of the opinion that if you sell a Class A-1 note,
you will recognize gain or loss equal to the difference between the amount
realized on the sale, other than amounts attributable to, and taxable as,
accrued interest, and your adjusted tax basis in the Class A-1 note. Your
adjusted tax basis in a note will equal your cost for the Class A-1 note,
decreased by any amortized premium and any payments other than interest made on
the Class A-1 note and increased by any market discount or original issue
discount previously included in income. Any gain or loss will generally be a
capital gain or loss, other than amounts representing accrued interest or
market discount, and will be long-term capital gain or loss if the Class A-1
note was held as a capital asset for more than one year. In the case of an
individual taxpayer, the maximum long-term capital gains tax rate is lower than
the maximum ordinary income tax rate. Any capital losses realized may be
deducted by a corporate taxpayer only to the extent of capital gains and by an
individual taxpayer only to the extent of capital gains plus $3,000 of other
U.S. income.

Market Discount
      In the opinion of Mayer, Brown & Platt, you will be considered to have
acquired a Class A-1 note at a "market discount" to the extent the remaining
principal amount of the note exceeds your tax basis in the note, unless the
excess does not exceed a prescribed de minimis amount. If the excess exceeds
the de minimis amount, you will be subject to the market discount rules of
Sections 1276 and 1278 of the Code with regard to the note.

                                      144
<PAGE>

      In the case of a sale or other disposition of a Class A-1 note subject to
the market discount rules, Section 1276 of the Code requires that gain, if any,
from the sale or disposition be treated as ordinary income to the extent the
gain represents market discount accrued during the period the note was held by
you, reduced by the amount of accrued market discount previously included in
income.

      In the case of a partial principal payment of a Class A-1 note subject to
the market discount rules, Section 1276 of the Code requires that the payment
be included in ordinary income to the extent the payment does not exceed the
market discount accrued during the period the note was held by you, 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 with principal payable in two or more installments, such
as the Class A-1 notes, the manner in which market discount is to be accrued
will be described in Treasury regulations not yet issued. Until these Treasury
regulations are issued, you should follow the explanatory conference committee
Report to the Tax Reform Act of 1986 for your accrual of market discount. This
Conference Committee Report indicates that holders of these obligations may
elect to accrue market discount either on the basis of a constant interest rate
or as follows:

    .  for those obligations that have original issue discount, market
       discount shall be deemed to accrue in proportion to the accrual of
       original issue discount for any accrual period; and

    .  for those obligations which do not have original issue discount, 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 at the beginning of the
       accrual period.

      Under Section 1277 of the Code, if you incur or continue debt that is
used to purchase a Class A-1 note subject to the market discount rules, and the
interest paid or accrued on this debt in any taxable year exceeds the interest
and original issue discount currently includible in income on the note,
deduction of this excess interest must be deferred to the extent of the market
discount allocable to the taxable year. The deferred portion of any interest
expense will generally be deductible when the market discount is included in
income upon the sale, repayment, or other disposition of the indebtedness.

      Section 1278 of the Code allows a taxpayer to make an election to include
market discount in gross income currently. If an election is made, the
previously described rules of Sections 1276 and 1277 of the Code will not apply
to the taxpayer.

      Due to the complexity of the market discount rules, we suggest that you
consult your tax advisors as to the applicability and operation of these rules.


                                      145
<PAGE>

Premium
      In the opinion of Mayer, Brown & Platt, you will generally be considered
to have acquired a Class A-1 note at a premium if your tax basis in the note
exceeds the remaining principal amount of the note. In that event, if you hold
a Class A-1 note as a capital asset, you may amortize the premium as an offset
to interest income under Section 171 of the Code, with corresponding reductions
in your tax basis in the note if you have made an election under Section 171 of
the Code. Generally, any amortization is on a constant yield basis. However, in
the case of bonds with principal payable in two or more installments, like the
Class A-1 notes, the previously discussed conference report, which indicates a
Congressional intent that amortization be in accordance with the rules that
will apply to the accrual of market discount on these obligations, should be
followed for the amortization of such premium. We suggest that you consult your
tax advisor as to the applicability and operation of the rules regarding
amortization of premium.

Backup Withholding
      Mayer, Brown & Platt is of the opinion that, backup withholding taxes
will be imposed on payments to you at the rate of 31% on interest paid, and
original issue discount accrued, if any, on the Class A-1 notes if, upon
issuance, you fail to supply the manager or its broker with a certified
statement, under penalties of perjury, containing your name, address, correct
taxpayer identification number, and a statement that you are not required to
pay backup withholding. Exempt investors, such as corporations, tax-exempt
organizations, qualified pension and profit sharing trusts, individual
retirement accounts or non-resident aliens who provide certification of their
status as non-resident are not subject to backup withholding. Information
returns will be sent annually to the IRS by the manager and to you stating the
amount of interest paid, original issue discount accrued, if any, and the
amount of tax withheld from payments on the Class A-1 notes. We suggest that
you consult your tax advisors about your eligibility for, and the procedure for
obtaining, exemption from backup withholding.

      Recently, the Treasury Department issued new regulations which modify the
backup withholding and information reporting rules described in this section.
The new regulations will generally be effective for payments made after
December 31, 2000, subject to transition rules. We suggest that you consult
your own tax advisors regarding these new regulations.

                             Australian Tax Matters

      The following statements with respect to Australian taxation are the
material tax consequences to the United States Class A-1 noteholders of holding
Class A-1 notes and are based on advice received by the manager. It is
suggested that purchasers of Class A-1 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 Class A-1 notes.


                                      146

Payments of Principal, Premiums and Interest
      Under existing Australian tax law, non-resident holders of 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, are not subject to Australian income tax on
payments of interest or amounts in the nature of interest, other than interest
withholding tax, which is currently 10%, on interest or amounts in the nature
of interest paid on the 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 Income Tax Assessment Act 1936 of the
Commonwealth of Australia, an exemption from Australian interest withholding
tax applies provided all prescribed conditions are met.

      These conditions are:

    .  the issuer trustee is a company that is a resident of Australia when
       it issues the notes and when interest, as defined in section 128A
       (1AB) of the Income Tax Assessment Act, is paid; and

    .  the notes, or a global bond or note or interests in such a global
       bond or note, were issued in a manner which satisfied the public
       offer test as prescribed under section 128F of the Income Tax
       Assessment Act.

      The issuer trustee will seek to issue the Class A-1 notes and interests
in any global Class A-1 note in a way that will satisfy the public offer test
and otherwise meet the requirements of section 128F of the Income Tax
Assessment Act including by listing the Class A-1 notes.

      The public offer test will not be satisfied if the issuer trustee knew or
had reasonable grounds to suspect that the Class A-1 notes were being or would
later be acquired directly or indirectly by an associate of the issuer trustee
within the meaning of that section, other than in the capacity of a dealer,
manager or underwriter in relation to the placement of a note. "Associate" for
these purposes is widely defined and means, generally speaking, in relation to
an issuer acting in the capacity of a trustee, the beneficiaries of the trust,
and any "associates" of those beneficiaries. Thus the relevant associates of
the issuer trustee in the present case will be Commonwealth Bank as the
residual unitholder of the trust and the associates of Commonwealth Bank and
the other beneficiaries of the trust, if any, from time to time.

      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 of the Income Tax Assessment Act, which, as
discussed, would be an associate of the residual unitholder, if, at the time of
the payment, the issuer trustee knows, or has reasonable grounds to suspect,
that the person is an associate.

      If, for any reason, the interest paid by the issuer trustee is not exempt
from interest withholding tax, the treaty titled "Convention for the Avoidance
of Double Taxation and the

                                      147
<PAGE>

Prevention of Fiscal Evasion with respect to Taxes on Income" between the
United States and Australia may apply. This treaty provides that interest which
has its source in Australia, and to which a United States resident, as defined
in the treaty and who is entitled to the benefit of the treaty, is beneficially
entitled, may be taxed in Australia, but that any tax charged shall not exceed
10% of the gross amount of interest. However, this provision will not apply
where the indebtedness giving rise to the interest entitlement is effectively
connected with:

    .  the United States resident beneficial owner's permanent
       establishment, at or through which it carries on business in
       Australia; or

    .  the United States resident beneficial owner's fixed base, situated in
       Australia, from which it performs independent personal services.

Profit on Sale
      Under existing Australian law, non-resident holders of notes will not be
subject to Australian income tax on profits derived from the sale or disposal
of the notes provided that:

    .  the notes are not held, and the sale or disposal does not occur, as
       part of a business carried on, at or through a permanent
       establishment in Australia; and

    .  the profits do not have an Australian source.

      The source of any profit on the disposal of notes will depend on the
factual circumstances of the actual disposal. Where the 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 a business carried on, at or through a permanent
establishment in Australia, the profit would not be expected to have an
Australian source.

      However, there are specific withholding tax rules that can apply to treat
a portion of the sale price of notes as interest for withholding tax purposes
and which amounts are not covered by the exemption conditions in section 128F
of the Income Tax Assessment Act. These rules can apply when:

    .  notes are sold for any amount in excess of their issue price prior to
       maturity to a purchaser who is either a resident who does not acquire
       the notes in the course of carrying on business in a country outside
       Australia at or through a permanent establishment in that country or
       a non-resident that acquires the notes in the course of carrying on a
       business in Australia at or through a permanent establishment in
       Australia; or

    .  notes are sold to an Australian resident in connection with a
       "washing arrangement" as defined in section 128A (1AB) of the Income
       Tax Assessment Act.


                                      148

Goods and Services Tax
      From July 1, 2000, a goods and services tax will be payable by all
entities which make taxable supplies in Australia. If an entity, such as the
issuer trustee, makes any taxable supply on or after July 1, 2000, it will have
to pay goods and services tax equal to 1/11th of the total value of the
consideration for that supply. However, on the basis of the current goods and
services tax legislation and regulations, the issue of the Class A-1 notes and
the payment of interest or principal on the Class A-1 notes to you will not be
taxable supplies.

      If the supply is

    .  "GST free," the issuer trustee does not pay a goods and services tax
       on the supply and can obtain goods and services tax credits for goods
       and services taxes paid on things acquired to make the supply; or

    .  "input taxed," which includes financial supplies, the issuer trustee
       does not pay a goods and services tax on the supply, but is
       restricted in its ability to claims to goods and services tax credits
       for amounts, including goods and services tax, paid to acquire things
       relating to the making of that supply.

      Services provided to the issuer trustee will be a mixture of taxable and
input taxed supplies for goods and services tax purposes. If a supply is
taxable, the supplier is liable to pay goods and services tax in respect of
that supply and must rely on a contractual provision to recoup that goods and
services tax from the issuer trustee. The scope of "financial supplies," and
certain supplies that are not financial supplies, is determined by the goods
and services tax legislation and regulations, as amended from time to time.
Under the series supplement, the issuer trustee's fee will only be able to be
increased by reference to the issuer's trustee goods and services tax
liability, if any, if:

    .  the issuer trustee and the manager agree or, failing agreement, the
       issuer trustee's goods and services tax liability is determined by an
       expert; and

    .  the increase will not result in the reduction, qualification or
       withdrawal of the credit rating of any notes or redraw bonds.

      The manager and the servicer may agree to adjust the manager's fee and
the servicer's fee provided that the adjustment will not result in the
reduction, qualification or withdrawal of the credit rating of any notes or
redraw bonds.

      If amounts payable by the issuer trustee are treated as the consideration
for a taxable supply under the goods and services tax legislation or are
increased by reference to the relevant supplier's goods and services tax
liability, the issuer trustee may not be entitled to an input tax credit for
that increase and the expenses of the trust will increase, resulting in a
decrease in the funds available to the trust to pay you.

      The goods and services tax may increase the cost of repairing or
replacing damaged properties offered as security for housing loans. However, it
is a condition of Commonwealth Bank's loan contract and mortgage documentation
that the borrower must maintain full replacement value property insurance at
all times during the loan term.

                                      149
<PAGE>

      The goods and services tax legislation, in certain circumstances, treats
the issuer trustee as making a taxable supply if it enforces a security by
selling the mortgaged property and applying the proceeds of sale to satisfy the
housing loan. The issuer trustee will have to account for goods and services
tax out of the sale proceeds, with the result that the remaining sale proceeds
may be insufficient to cover the unpaid balance of the related loan. However,
the general position is that a sale of existing residential property is an
input taxed supply for goods and services tax purposes and so the enforced sale
of property which secures the housing loans will generally not be treated as a
taxable supply under these provisions. As an exception, the issuer trustee may
still have to account for goods and services tax out of the proceeds of sale
recovered when a housing loan is enforced where the borrower is an enterprise
which is registered for goods and services tax purposes, uses the mortgaged
property as an asset of its enterprise and any of the following are relevant:

    .  the property is no longer being used as a residence; or

    .  the property is used as commercial residential premises such as a
       hostel or boarding house; or

    .  the borrower is the first vendor of the property--the borrower built
       the property; or

    .  the mortgaged property has not been used predominantly as a
       residence.

      Because the issuer trustee is an insured party under the mortgage
insurance policies, it may have to account for goods and services tax in
respect of any claim payment received. However, under the goods and services
tax legislation, where the claim payment is made in respect of an insurance
policy on which the insured was not entitled to a goods and services tax credit
on the premium payable, the insured does not have to account for goods and
services tax in respect of the claim payment. The provisions of the goods and
services tax legislation relating to insurance are currently the subject of
review. It is not possible to predict the final form of the legislation with
any certainty.

      Any reduction as a result of goods and services tax in the amount
recovered by the issuer trustee when enforcing the housing loans will decrease
the funds available to the trust to pay you to the extent not covered by the
mortgage insurance policies. The extent to which the issuer trustee is able to
recover an amount on account of the goods and services tax, if any, payable on
the proceeds of sale in the circumstances described in this section, will
depend on the terms of the related mortgage insurance policy.

Other Taxes
      No stamp, issue, registration or similar taxes are payable in Australia
in connection with the issue of the Class A-1 notes. Furthermore, a transfer
of, or agreement to transfer, notes executed outside of Australia will not be
subject to Australian stamp duty.

                 Enforcement of Foreign Judgments in Australia

      Securitisation Advisory Services Pty Limited is an Australian proprietary
company registered 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 Securitisation Advisory Services Pty Limited in respect of a 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 Securitisation Advisory Services Pty
Limited 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:

    .  the proceedings in New York State or United States Federal Court, as
       applicable, involved a denial of the principles of natural justice;

    .  the judgment is contrary to the public policy of the relevant
       Australian jurisdiction;

    .  the judgment was obtained by fraud or duress or was based on a clear
       mistake of fact;

    .  the judgment is a penal or revenue judgment; or

    .  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. Securitisation Advisory Services Pty Limited 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 proceeding arising out of this offering. Securitisation Advisory
Services Pty Limited has appointed [       ], as its agent upon whom process
may be served in any such action.

      All of the directors and executive officers of Securitisation Advisory
Services Pty Limited, and certain experts named in this prospectus, 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 Class A-1 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. Securitisation Advisory Services Pty
Limited has been advised by its Australian counsel Clayton Utz, that, based on
the restrictions discussed in this section, 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, which may change in
the future, payments by an Australian resident to, or on behalf of the
following payees may only be made with Reserve Bank of Australia approval:

    .   the Government of Iraq or its agencies or nationals;

    .   the authorities of the Federal Republic of Yugoslavia (Serbia and
        Montenegro); or

    .   the Government of Libya or any public authority or controlled entity
        of the Government of Libya.

                              ERISA Considerations

      Subject to the considerations discussed in this section, the Class A-1
notes are eligible for purchase by employee benefit plans.

      Section 406 of the Employee Retirement Income Security Act and Section
4975 of the Code prohibit a pension, profit-sharing or other employee benefit
plan, as well as individual retirement accounts and certain types of Keogh
Plans from engaging in certain transactions with persons that are "parties in
interest" under ERISA or "disqualified persons" under the Code with respect to
these Benefit Plans. A violation of these "prohibited transaction" rules may
result in an excise tax or other penalties and liabilities under ERISA and the
Code for these 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.

      Some transactions involving the purchase, holding or transfer of the
Class A-1 notes might be deemed to constitute prohibited transactions under
ERISA and the Code if assets of the trust were deemed to be assets of a Benefit
Plan. Under a regulation issued by the United States Department of Labor, the
assets of the trust 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 trust and none of the exceptions contained in the regulation
is applicable. An equity interest is defined under the 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, at the time of
their initial issuance that the Class A-1 notes should be treated as debt
without substantial equity features for purposes of the regulation and that the
Class A-1 notes do not constitute equity interests in the trust for purposes of
the regulation. The debt characterization of the notes could change after their
initial issuance if the trust incurs losses.

      However, without regard to whether the Class A-1 notes are treated as an
equity interest for these purposes, the acquisition or holding of the Class A-1
notes by or on behalf of a Benefit Plan could be considered to give rise to a
prohibited transaction if the trust, the issuer trustee, the servicer, the
manager, the Class A-1 note trustee, the seller or the security

                                      152
<PAGE>

trustee is or becomes a party in interest or a disqualified person with respect
to these Benefit Plans. 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 a note. Included among
these exemptions are:

    .   Prohibited Transaction Class Exemption 96-23, regarding transactions
        effected by "in-house asset managers";

    .   Prohibited Transaction Class Exemption 90-1, regarding investments
        by insurance company pooled separate accounts;

    .   Prohibited Transaction Class Exemption 95-60, regarding transactions
        effected by "insurance company general accounts";

    .   Prohibited Transaction Class Exemption 91-38, regarding investments
        by bank collective investment funds; and

    .   Prohibited Transaction Class Exemption 84-14, regarding transactions
        effected by "qualified professional asset managers."

      By your acquisition of a Class A-1 note, you shall be deemed to represent
and warrant that your purchase and holding of the Class A-1 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.

      If you are a plan fiduciary considering the purchase of any of the Class
A-1 notes, you should consult your tax and legal advisors regarding whether the
assets of the Trust would be considered plan assets, the possibility of
exemptive relief from the prohibited transaction rules and other issues and
their potential consequences.

                        Legal Investment Considerations

      The Class A-1 notes will not constitute "mortgage related securities" for
purposes of the Secondary Mortgage Market Enhancement Act of 1984, because the
originator of the housing loans was not subject to United States state or
federal regulatory authority. Accordingly, some U.S. institutions with legal
authority to invest in comparably rated securities based on such housing loans
may not be legally authorized to invest in the Class A-1 notes. No
representation is made as to whether the 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 any regulatory authorities. You are urged to consult with your
counsel concerning the status of the Class A-1 notes as legal investments for
you.

                             Available Information

      Securitisation Advisory Services Pty Limited, as manager, has filed with
the SEC a registration statement under the Securities Act with respect to the
Class A-1 notes offered pursuant to this prospectus. For further information,
reference should be made to the registration statement and amendments thereof
and to the exhibits thereto, which are available for inspection without charge
at the public reference facilities maintained by the SEC at 450 Fifth Street,
N.W., Washington, D.C. 20549; and at the SEC's regional offices at Citicorp
Center, 500 West Madison Street, Suite 1400, Chicago, Illinois 60661, and 7
World Trade Center, Suite 1300, New York, New York 10048. Copies of the
registration statement, including any amendments or exhibits, may be obtained
from the Public Reference Section of the SEC at 450 Fifth Street, N.W.,
Washington, D.C. 20549, at prescribed rates. The SEC also maintains a World
Wide Web site which provides on-line access to reports, proxy and information
statements and other information regarding registrants that file electronically
with the SEC at the address "http://www.sec.gov."

                              Ratings of the Notes

      The issuance of the Class A-1 and Class A-2 notes will be conditioned on
obtaining a rating of AAA by Standard & Poor's, Aaa by Moody's and AAA by Fitch
IBCA. The issuance of the Class B notes will be conditioned on obtaining a
rating of AAA by Standard & Poor's and AAA by Fitch IBCA. You should
independently evaluate the security ratings of each class of notes from similar
ratings on other types of securities. A security rating is not a recommendation
to buy, sell or hold securities. A rating does not address the market price or
suitability of the Class A-1 notes for you. A rating may be subject to revision
or withdrawal at any time by the rating agencies. 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 of the notes. The
ratings of the Class A-1 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-1 and A-2 notes, the availability of excess interest
collections after payment of interest on the notes and the trust's expenses,
the mortgage insurance policies, the availability of the Liquidity Facility,
the creditworthiness of the swap providers and the mortgage insurer and the
foreign currency rating of Australia. The Commonwealth of Australia's current
foreign currency long term debt rating is [    ] by Standard & Poor's, [    ]
by Moody's and [    ] by Fitch IBCA. 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. None of the
rating agencies have been involved in the preparation of this prospectus.

      The underwriting agreement provides that the underwriters are obligated,
subject to certain conditions in the underwriting agreement, to purchase all of
the Class A-1 notes if any are [not] purchased. The underwriting agreement may
be terminated if there is a default by the underwriters.

      The underwriters propose to initially offer the Class A-1 notes at the
public offering prices on the cover page of this prospectus and to selling
group members at the price less a concession not in excess of the respective
amounts set forth in the following table, expressed as a percentage of the
relative principal balance. The underwriters and selling group members may
reallow a discount not in excess of the respective amounts set forth in the
following table to other broker/dealers. After the initial public offering, the
public offering price and concessions and discounts to broker/dealers may be
changed by the representative of the underwriters.

      Commonwealth Bank estimates that the out-of-pocket expenses for this
offering will be approximately US$[    ] million.

      J.P. Morgan has informed Commonwealth Bank and the manager that the
underwriters do not expect discretionary sales by them to exceed 5% of the
principal balance of the Class A-1 notes.

      Commonwealth Bank and the manager have agreed to indemnify the
underwriters against civil liabilities under the Securities Act, or contribute
to payments which the underwriters may be required to make in that respect.

      The representative, on behalf of the underwriters, may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Class A-1 notes. The underwriters may engage in over-allotment, stabilizing
transactions, syndicate covering transactions and penalty bids in accordance
with Regulation M under the Exchange Act.

    .   Over-allotment involves syndicate sales in excess of the offering
        size, which creates a syndicate short position;

                                      155
<PAGE>

    .   Stabilizing transactions permit bids to purchase the underlying
        security so long as the stabilizing bids do not exceed a specified
        maximum;

    .   Syndicate covering transactions involve purchases of the Class A-1
        notes in the open market after the distribution has been completed
        in order to cover syndicate short positions;

    .   Penalty bids permit the underwriters to reclaim a selling concession
        from a syndicate member when the Class A-1 notes originally sold by
        a syndicate member are purchased in a syndicate covering transaction
        to cover syndicate short positions.

      Stabilizing transactions, syndicate covering transactions and penalty
bids may cause the price of the Class A-1 notes to be higher than it would
otherwise be in the absence of these transactions. These transactions, if
commenced, may be discontinued at any time.

      Pursuant to the underwriting agreement, the manager, Commonwealth Bank
and the issuer trustee have agreed to indemnify the underwriters against
certain liabilities, including civil liabilities under the Securities Act, or
contribute to certain payments which the underwriters may be responsible for.

      In the ordinary course of its business, some of the underwriters and
some of their affiliates have in the past and may in the future engage in
commercial and investment banking activities with Commonwealth Bank and its
affiliates.

 Voting Entitlements..............  on a particular date means the number of
                                    votes which a Voting Secured Creditor would
                                    be entitled to exercise if a meeting of

                                    dividing the Secured Moneys owing to that
                                    Voting Secured Creditor by 10 and rounding

Item 37. Undertakings.

   The undersigned registrant hereby undertakes that 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.

   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.
