Pty. Limited as manager and Perpetual Trustee Company Limited as issuer
trustee, as amended from time to time. 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 2000-2G
Medallion Trust, 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 2000-2G 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 2000-2G
Medallion Trust. See "Description of the Trust."

      The Series 2000-2G 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 except in accordance
with the transaction documents. For a description of floating charges and
crystallization see "The Security Trust Deed--Nature of the Charge" on page
114.

      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:

</TABLE>

      The initial support percentage in the preceding table is the initial
balance of the Class B notes, as a percentage of the aggregate invested amount
of the notes to be issued on the closing date.

      In certain circumstances, the issuer trustee may issue redraw bonds as
described in "Description of the Class A-1 Notes--Redraws and Further
Advances--Issue of Redraw Bonds." 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 GE Mortgage Insurance Pty Ltd will
provide full coverage for all principal due on certain of the housing loans
which are generally those which had a loan to value ratio greater than 80% at
the time of origination.

      A master mortgage insurance policy issued by PMI Mortgage Insurance Ltd
will provide full coverage for all principal due on the balance of the housing
loans.

Seller Deposit
      If Commonwealth Bank is assigned a short-term deposit credit rating by
Moody's of less than P1 or is assigned a long term deposit credit rating by
Standard & Poor's or Fitch of less than BBB, or in each case, a lesser rating
as agreed between

                                       13
<PAGE>

the manager, the issuer trustee, Commonwealth Bank and the relevant rating
agency, it must deposit an amount in an account, which may be 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 where the borrowers' housing loans do not have a waiver of
set-off. 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 swaps;

.   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 swaps; and

.   two currency swaps 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 any distribution date falling on or after the
earlier of the distribution date falling in December 2007 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
September 1, 2000. 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 noteholders and redraw
bondholders owning 75% of the aggregate outstanding principal balance of the
notes and redraw bonds consent to receiving the outstanding principal balance
of the notes and redraw bonds, as reduced by losses allocated against the notes
and redraw bonds, plus accrued interest on the outstanding principal balance of
the notes and redraw bonds. If the issuer trustee, at the direction of the
manager, proposes to exercise its option to redeem the notes and redraw bonds
on a distribution date during or after December 2007 at the lesser amount as
described above but is unable to do so because noteholders and redraw
bondholders owning 75% of the aggregate outstanding principal balance of the
notes and redraw bonds have not approved the redemption, then the margin on the
Class A-1 notes as from that distribution date will remain at, or revert to,
the margin as at the closing date.

                             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
terms to stated maturity as of the cut-off date of no more than 30 years.
Commonwealth Bank expects the pool of housing loans to have characteristics
similar to the following:

                      Close of Business on August 16, 2000

<TABLE>

Weighted Average Current Loan-to-Value Ratio............................ 71.16%
Maximum Current Loan-to-Value Ratio..................................... 95.00%
</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. There
has been no revaluation of the properties specifically for the purposes of the
issue of the Class A-1 notes. Revaluations are only conducted in circumstances
where a borrower under a housing loan seeks additional funding, or seeks to
partially discharge an existing security, or where a borrower is in default and
Commonwealth Bank is considering enforcement action. Thus, if collateral has
been released from the mortgage securing a housing loan or if the property
securing the housing loan has reduced in value, 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 the above table,
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, at its sole option, 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 noteholders and redraw bondholders owning 75%
      of the aggregate outstanding principal balance of the notes and
      redraw bonds consent to receiving the outstanding principal balance
      of the notes and redraw bonds, as reduced by losses allocated against
      the notes and redraw bonds, plus accrued interest on the outstanding
      principal balance of the 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."

      If a Class A-1 noteholder is an Australian resident withholding tax of
48.5% must be deducted, unless the Class A-1 noteholder supplies the issuer
trustee with their Australian Business Number or Tax File Number.

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
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" on page 166.

ERISA Considerations
      In general, subject to the restrictions described in "ERISA
Considerations", below the Class A-1 notes will be eligible for purchase by
retirement plans subject to the Employee Retirement Income Security Act of
1974, as amended ("ERISA") or Section 4975 of the U.S. Internal Revenue Code of
1986, as amended (the "Code"). Investors should consult their counsel with
respect to the consequences under ERISA and the Code of the plan's acquisition
and ownership of the Class A-1 notes.

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 Clearstream, Luxembourg or Euroclear outside of the United States. Transfers
within the Depository Trust Company, Clearstream, Luxembourg 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 Clearstream, Luxembourg or Euroclear, on the
other hand, will take place in the Depository Trust Company through the
relevant depositories of Clearstream, Luxembourg 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, excluding any insurance premiums and related charges
       payable to Commonwealth Bank;

    .  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
                                       18
<PAGE>

       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 certain fees and expenses of
the trust 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 such
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.

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 providers 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 providers, 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

                                       19
<PAGE>

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 four
pages summarize the flow of payments.

                                  Risk Factors

      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.
There may be other unforeseen reasons why you might not receive principal or
interest on your Class A-1 notes. You should also read the detailed information
set out elsewhere in the prospectus.

 <C>                                  <S>
 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
                                         yield you expected to receive.

 You face an additional possibility   .  Although Commonwealth Bank could have
 of loss because the issuer trustee      legally assigned the title to the
 does not hold legal title to the        housing loans to the issuer trustee,
 housing loans                           initially it will assign only
                                         equitable title to the housing loans
                                         to the issuer trustee. The borrowers
                                         will not be notified of the equitable
                                         assignment. The housing loans will be
                                         legally assigned to the issuer trustee
                                         only upon the occurrence of a
                                         perfection of title event, as

                                         Because the issuer trustee does not
                                         hold legal title to the housing loans,
                                         you will be subject to the following
                                         risks, which may lead to a failure to
                                         receive collections on the housing

                                      .  Until a borrower has notice of the
                                         assignment, that borrower is not bound
                                         to make payments under its housing

                                         higher rates of principal prepayment
                                         than you expected, which could affect
                                         the yield on your Class A-1 notes.

 There are limits on the amount       .  If the interest collections during a

                                         will request an advance under the
                                         liquidity facility. In the event that
                                         there is not enough money available
                                         under the liquidity facility, you may
                                         not receive a full payment of interest
                                         on that distribution date, which will
                                         reduce the yield on your Class A-1
                                         notes.

supplement. The Series 2000-2G Medallion Trust is separate and distinct from
any other trust established under the master trust deed. The assets of the
Series 2000-2G 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 2000-2G Medallion Trust.

       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.

                    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 PMI Mortgage
       Insurance Ltd and GE Mortgage Insurance Pty Ltd 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 appearing on Commonwealth Bank's
       records as 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
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.


                                      39

Transfer and Assignment of the Housing Loans
      The housing loans assigned to the trust on the closing date 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 the collections, subject to certain
unrelated exceptions, 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 lodgement 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 assigned to the issuer trustee is secured by an "all
moneys" mortgage, which may also secure other financial indebtedness. The
seller will also assign 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 trust. The other loans are not assets of
the Series 2000-2G 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.

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;

    .  at the time the seller entered into the housing loan, it did so 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
       any notice that the relevant borrower did not have the legal capacity
       to enter into the relevant mortgage;

    .  the seller is the sole legal and beneficial owner of the housing loan
       and the related securities assigned to the issuer trustee as trustee
       of the trust and, to its knowledge, subject to the above paragraph in
       relation to second mortgages in respect of which the seller is not
       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;

                                       41
<PAGE>

    .  each housing loan is, or will on the closing date be, insured under a
       mortgage insurance policy;

    .  except in relation to fixed rate housing loans or those which can be
       converted to a fixed rate or a fixed margin relative to a benchmark
       and applicable laws, binding codes and competent authorities binding
       on the seller or as may be otherwise provided in the corresponding
       mortgage documents, there is no 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 from the seller's general housing loan pool;

      .  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
         by the borrower, will not exceed A$750,000;

      .  the borrower is required to repay that loan within 30 years of the
         cut-off date;

      .  no payment from the borrower under the housing loan is in arrears
         for more than 30 consecutive days;

      .  the housing loan is not of a type with only interest payable
         during the term and with "bullet" repayment of all principal at
         the end of its term;

      .  it is or has been fully drawn;

      .  it was originated on or after 1 November, 1996;

      .  the borrower under the housing loan is not an employee of the
         seller who is paying a concessional rate of interest under the
         housing loan as a result of that employment; and

      .  it was advanced, and is repayable, in Australian dollars.

The issuer trustee has not investigated or made any inquiries regarding the
accuracy of these representations and warranties and has no obligation to do
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.

                                       42
<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, including that a housing
loan not meeting the eligibility criteria has been included in the housing loan
pool, 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, cheques and in most cases automatic transfer.

                                       43

    .  They are governed by the laws of one of the following Australian
       States or Territories:

      .  New South Wales;

      .  Victoria;

      .  Western Australia;

      .  Queensland;

      .  South Australia;

      .  Northern Territory;

      .  Tasmania; or

      .  the Australian Capital Territory.

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 by Commonwealth Bank as of the
close of business on August 16, 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 but any changes to the pool will be minor, as set out
below.

      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 the table on page 16,
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

                                       52
<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 a 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

                                      53
<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 acknowledgement 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.


                                       54
<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," "Interest
Offset" 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

                                       55
<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, at present fixed rate loans allow for early repayment by the
borrower of up to A$10,000 in any 12 month period without any break fees or
break benefits being applicable.

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.

                                       56
<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 generally had a loan-to-value ratio of greater
       than around 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 represent liabilities of GE Mortgage
Insurance Pty Ltd.

      The high LTV mortgage insurance policies insure the issuer trustee
against losses in respect of housing loans which generally had a loan-to-value
ratio of greater than around

                                       57
<PAGE>

80% at the time of origination. They were usually 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 cancelled by the mortgage
insurer. An individual high LTV mortgage insurance policy may be cancelled 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;

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

                                       58
<PAGE>

    .  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;

             .  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;

                                       59
<PAGE>

             .  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 PMI Mortgage
Insurance Ltd. The master mortgage insurance policy insures the issuer trustee
against losses in respect of housing loans which are not insured under a high
LTV mortgage insurance policy. 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.

         amount of any goods and services tax included in such costs, fees,
         disbursements or commissions specifically identified under this
         section headed "costs incurred on sale of the mortgaged property
         which include"; and

      .  any amounts applied with the prior written consent of PMI Mortgage
         Insurance Ltd to discharge a security interest having priority
         over the insured mortgage,

      less the following deductions:

    .  the gross proceeds of sale of the mortgaged property; and

    .  the following amounts to the extent they have not already been
       applied to the credit of the loan account:

      .  compensation received for any part of the mortgaged property or
         any collateral security that has been resumed or compulsorily
         acquired;

      .  all rents collected and other profits received relating to the

      .  the amount of any input tax credit to which the insured is
         entitled in respect of an acquisition which relates to any costs,
         fees, disbursements or commissions specifically identified under
         the section above headed "costs incurred on sale of the mortgaged
         property which include".

not include the following amounts:

    .  default rate interest;

    .  early repayment fees;

    .  break funding costs;

    .  costs of removal, clean up and restoration arising from contamination
       of the mortgaged property;

       complete improvements;

Reduction in a Claim
      The amount of a claim under the mortgage insurance policy may be reduced

making a false or misleading statement, assurance or representation to the
borrower or any guarantor, or the insured consenting to, without the written
approval of PMI Mortgage Insurance Ltd:

    .  the creation of any lease, licence, easement, restriction or other
       notification affecting the mortgaged property; or

    .  an increase in or acceleration of the payment obligation of the
       borrower under any security interest having priority over the insured
       mortgage.

      Under the PMI master policy, the amount of a claim may also be reduced in
other circumstances including where the seller, the servicer, the trust manager
or the issuer trustee do not comply with their duties of disclosure or the
requirements of the PMI master policy.

      The mortgage insurance policy does not cover losses resulting from a
credit tribunal or court re-opening an unjust insured mortgage, collateral
security or loan account under section 70 of the Consumer Credit Code or
annulling or reducing any unconscionable interest rate change, fee or charge
under section 72 of the Consumer Credit Code.

Submission for Payment of Claims
      The insured must submit a claim for loss providing all documents and
information reasonably required by PMI Mortgage Insurance Ltd within 30 days
of:

    .  settlement of the sale of the corresponding mortgaged property; or

    .  notification by PMI Mortgage Insurance Ltd to submit a claim for
       loss.

                       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

                                       64
<PAGE>

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 on page I-1, 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. The Class A-1 note trust deed has been duly qualified under the
Trust Indenture Act of 1939 of the United States.

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 Clearstream Banking, societe anonyme,
Clearstream, Luxembourg (previously named 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. Clearstream, Luxembourg and Euroclear
will hold omnibus positions on behalf of their respective participants, through
customers' securities accounts in Clearstream, Luxembourg 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.

      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

                                       65
<PAGE>

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 Clearstream, Luxembourg
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 Clearstream,
Luxembourg 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. Clearstream, Luxembourg participants and Euroclear participants may not
deliver instructions directly to their system's depositary.

      Because of time-zone differences, credits of securities in Clearstream,
Luxembourg 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 Clearstream, Luxembourg participant or Euroclear
participant on that business day. Cash received in Clearstream, Luxembourg or
Euroclear as a result of sales of securities by or through a Clearstream,
Luxembourg 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 Clearstream, Luxembourg
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 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

                                       66
<PAGE>

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,
the security trustee or the Class A-1 note 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.

      Clearstream, Luxembourg is a company with limited liability incorporated
under the laws of Luxembourg. Clearstream, Luxembourg holds securities for its

transactions between Clearstream, Luxembourg participants through electronic

dollars.

      Clearstream, Luxembourg participants are financial institutions around
the world, including underwriters, securities brokers and dealers, banks, trust

Clearstream, Luxembourg 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 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.

      Clearstream, Luxembourg and Euroclear have established an electronic
bridge between their two systems across which their respective participants may
settle trades with each other.

      Distributions on the Class A-1 notes held through Clearstream, Luxembourg
or Euroclear will be credited to the cash accounts of Clearstream, Luxembourg
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. Clearstream, Luxembourg 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 Clearstream, Luxembourg 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, Clearstream, Luxembourg and Euroclear have agreed to the
foregoing procedures in order to facilitate transfers of interests in Class A-1
notes among participants of DTC, Clearstream, Luxembourg 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:

    .  DTC or any replacement clearing agency, advises the Class A-1 note
       trustee in writing that DTC or such 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 manager, at its option, advises the issuer trustee, the Class A-1
       note trustee and DTC or any replacement clearing agency in writing
       that Class A-1 definitive notes are to be issued in replacement of
       the Class A-1 book-entry notes; or

    .  an event of default under the security trust deed has occurred and is
       subsisting and the beneficial owners of Class A-1 notes with an
       aggregate Invested Amount of greater than 50% of the aggregate
       Invested 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 within 30 days of such event instruct DTC (or its
replacement) to notify all of the beneficial owners of the Class A-1 notes of
the occurrence of the event and of the availability of definitive notes. DTC
will then surrender the Class A-1 book-entry notes and provide the relevant
registration instructions to the issuer trustee. The issuer trustee will then
issue and execute and the Class A-1 note trustee will authenticate and deliver
Class A-1 definitive notes of the same aggregate Invested Amount as those Class
A-1 book-entry notes. Class A-1 notes will be serially numbered if issued in
definitive form.

      No noteholder will be entitled to receive a Class A-1 definitive note
representing its interest, except as described in the preceding paragraph.

      Definitive notes will be transferable and exchangeable at the specified
offices of the Class A-1 note registrar. The Bank of New York, New York Branch
is the initial Class A-1 note registrar and its initial specified offices are
located at 101 Barclay Street, 21W, New York, New York, 10286 and c/o The Bank
of New York, London Branch, One Canada Square, Corporate Trust Services, 48th
Floor, London E14 5AL, U.K. The Class A-1 note registrar must at all times have
specified offices in London and New York. 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 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 or within a period, not exceeding thirty days, specified by
the Class A-1 note trustee prior to any meeting which includes Class A-1
noteholders under the master trust deed or the security trust deed.

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

    .  payments of interest, principal, fees and other amounts under the
       housing loans, excluding any insurance premiums and related charges
       payable to Commonwealth Bank;

    .  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, other than certain excluded amounts.

      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.

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;

    .  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, and amounts, if
         any, paid by the servicer representing interest on collections
         retained by the servicer for longer than 5 business days after
         receipt;

      .  income earned on Authorized Short-Term Investments received during
         the collection period other than interest in respect of cash
         collateral lodged by a

                                       72
<PAGE>

         Support Facility provider or the seller in an account other than
         the collections account;

      .  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 in relation to 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 to the manager of the management fee;

    .  fifth, payment of the servicer's fee;

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

    .  seventh, rateably towards payment of any amounts due to a support
       facility provider under a Support Facility, including interest due on
       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;

                                       73
<PAGE>

    .  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, while a currency swap remains in place for Class A-1 notes
       and payments are being made under it by the issuer trustee, rateably
       between themselves:

      .  payment to the currency swap providers 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 providers 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
         interest in relation to the Class A-2 notes from prior
         distribution dates and interest on that unpaid interest;

      .  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, while a currency swap remains in place for Class A-1 notes
       and payments are being made under it by the issuer trustee, 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, while a currency swap remains in place for Class A-1
       notes and payments are being made under it by the issuer trustee, to
       reimburse any principal charge-offs as an allocation to the Principal
       Amount on that distribution date;

    .  fourteenth, while a currency swap remains in place for Class A-1
       notes and payments are being made under it by the issuer trustee,
       payment to the manager of the arranging fee; and

    .  fifteenth, while a currency swap remains in place for Class A-1 notes
       and payments are being made under it by the issuer trustee, 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 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 in respect of the notes 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 Class A-1
notes accrue interest from and including the closing date to but excluding the
day upon which the final accrual period ends. The final accrual period for the
Class A-1 notes will end on, but exclude, the earlier of: the date upon which
the Stated Amount of the Class A-1 notes is reduced to zero; the date upon
which the Class A-1 notes are redeemed, unless upon presentation payment is
improperly withheld in which case interest will continue to accrue until the
earlier of the day on which the noteholder receives all sums due in respect of
the Class A-1 note or the seventh day after notice is given to the noteholder
that, where this is required, upon presentation of the Class A-1 note such
payment will be made, provided that payment is in fact made; and the date upon
which the Class A-1 note is deemed to be redeemed.

      Up to, but excluding, the distribution date falling in December 2007, the
interest rate for the Class A-1 notes for each accrual period will be equal to
LIBOR for that accrual period plus  %. If the issuer trustee has not redeemed
or attempted to redeem all of the Class A-1 notes by the distribution date
falling in December 2007, then subject to the following, the interest rate for
each accrual period commencing on or after that date will be equal to LIBOR for
that accrual period plus  %.

      If the issuer trustee, at the direction of the manager, proposes to
exercise its option to redeem the notes and redraw bonds on a distribution date
in or after December 2007 at their Stated Amount rather than their Invested
Amount, as described in "Optional Redemption of the Notes" below, but is unable
to do so because, following a meeting of noteholders and redraw bondholders
convened under the provisions of the security trust deed by the manager for
this purpose, the noteholders and redraw bondholders have not approved by an
Extraordinary Resolution the redemption of the notes and redraw bonds at their
Stated Amounts, then the interest rate for the Class A-1 notes for each accrual
period commencing on or after that distribution 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

                                       75
<PAGE>

the accrual period commencing on the distribution date in December 2007 if the
Class A-2 notes have not been redeemed by that date provided that the margin
will not increase, or will revert to the lower margin on and from a
distribution date, if the issuer trustee is unable to exercise its option on
that distribution date to redeem the notes and redraw bonds at their Stated
Amounts as described in the preceding paragraph. 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;

    .  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.

      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, except as described below, 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;

                                       76
<PAGE>

    .  Other Principal Amounts which are amounts received 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;

      .  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;

                                       77
<PAGE>

    .  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, while a currency swap remains in place for Class A-1 notes
       and payments are being made under it by the issuer trustee, to the
       currency swap providers 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"; and

    .  fifth, while a currency swap remains in place for Class A-1 notes and
       payments are being made under it by the issuer trustee, to the
       residual unitholder.

      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.

                                       78
<PAGE>

      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:

        (               SACAN)   (        SACBN       )
        ((NPC + NUP) X  -----) + (NUP X --------- X SP)
        (                SAN )   (         SAN        )

      where:

    .  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.

      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 providers in respect of repayment of the
       Stated Amount of the Class A-1 notes; and

    .  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.

                                       79

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 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 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

                                       80
<PAGE>

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 according to, in the case of
       the notes or redraw bonds, 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;

      .  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 and expenses
of the trust 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:

                                       81
<PAGE>

    .  first rateably amongst the following according to 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 swaps 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. The initial basis
swap provider and fixed rate swap provider will be Commonwealth Bank of
Australia, Level 7, 48 Martin Place, Sydney NSW 2000, Australia.

Basis Swap
      On each distribution date the issuer trustee will pay to the basis swap
provider an amount calculated by reference to the interest payable by borrowers
on the variable rate housing loans during the preceding collection period and
the income earned by the trust on

                                       82
<PAGE>

the collections account and any Authorized Short-Term Investments during that
collection period.

      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 last day of the
collection period preceding the previous distribution date and the Bank Bill
Rate plus a margin.

      The basis swap will terminate if the interest rate on the Class A notes
is increased following the distribution date in December 2007, provided that
the weighted average of the variable rates charged on the housing loans is
sufficient, assuming that all relevant parties comply with their obligations
under the housing loans and the transaction documents, to ensure that the
issuer trustee has sufficient funds to comply with its obligations under the
transaction documents as they fall due. 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 interest payable by
borrowers on the fixed rate housing loans, other than housing loans in relation
to which the issuer trustee has entered into an individual fixed rate swap as
described below, during the preceding collection period and the income earned
by the trust on the collections account and any Authorized Short-Term
Investments during that collection period.

      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 last day
of the collection period preceding 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.

      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 $10,000 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
unless, under the seller's current policies and procedures,

                                       83
<PAGE>

the prepayments are less than or equal to $10,000 in any 12 month period. 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.

Other Swaps
      The issuer trustee and the fixed rate swap provider may agree to enter
into separate fixed rate swaps in relation to one or more housing loans under
which the issuer trustee will pay the fixed rate swap provider the fixed
interest payable under the housing loans and the fixed rate swap provider will
pay the issuer trustee an amount calculated by reference to the Bank Bill Rate
plus a margin determined on or before the closing date.

      In addition, if the servicer offers interest rate cap products to
borrowers, the issuer trustee and the fixed rate swap provider will enter into
swaps to hedge the issuer trustee's risks in relation to such interest rate
caps.

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 each party affected by the
       illegality must make efforts to transfer its rights and obligations
       to avoid this illegality; or

    .  in the case of the basis swap only, at any time at the election of
       the basis swap provider provided that at the date of termination the
       weighted average of the variable rates charged on the housing loans
       is sufficient, assuming that all relevant parties comply with their
       obligations under the housing loans and the transaction documents, to
       ensure that the issuer trustee has sufficient funds to comply with
       its obligations under the transaction documents as they fall due.

                                       84
<PAGE>

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 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 each party affected by the
       illegality 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 short term credit rating of at least A-1 or a long term
       credit rating of A by Standard & Poor's;

    .  a long term credit rating of at least A-2 by Moody's; and

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

the fixed rate swap provider must:

      .  where it ceases to have a long term credit rating of at least A-2
         by Moody's or a short term credit rating of at least F1+ by Fitch:

             .  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;

             .  lodge cash collateral in an amount determined by the relevant
                rating agencies or, in certain circumstances, determined under
                the fixed rate swap; 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; and

      .  where it ceases to have either a short term credit rating of at
         least A-1 or a long term credit rating of A from Standard &
         Poor's:

             .  immediately seek to enter into, and enter into by no later
                than 60 days after the fixed rate swap provider ceases to have
                the relevant rating from Standard & Poor's, an agreement
                novating its rights and obligations under the fixed rate swap
                agreement in respect of the fixed rate swap to a replacement
                counterparty which holds the relevant ratings and, if a

                                       85
<PAGE>

                transfer has not occurred within 30 days, lodge cash
                collateral in an amount determined in accordance with the
                fixed rate swap; or

             .  (if the fixed rate swap provider is unable to effect a
                transfer in accordance with the above bullet point within 60
                days or if the fixed rate swap provider so elects) enter into
                such other arrangements in respect of the fixed rate swap
                which are satisfactory to the manager and 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.

      The fixed rate swap provider may satisfy its obligations following a
withdrawal or downgrade of a credit rating in any of the above manners as it
elects from time to time.

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:

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

    .  a short term credit rating of at least P-1 by Moody's; and

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

the basis swap provider must:

    .  prepay the amount that is expected to be due, as determined by the
       manager, 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.

      The basis swap provider may satisfy its obligations following a
withdrawal or downgrade of a credit rating in either of the above manners as it
elects from time to time.

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.

                                       86
<PAGE>

      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 adjust the rates of interest on the mortgage interest saver
accounts and, if necessary, the housing loans as described in "Description of
the Transaction Documents--Servicing of the Housing Loans--Administer Interest
Rates."

The Currency Swaps

Purpose of the Currency Swaps
      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,
as trustee of various series trusts established under the master trust deed,
will enter into a currency swap agreement with each currency swap provider.
Each currency swap will be governed by a standard form ISDA Master Agreement,
as amended by a supplementary schedule and a credit support annex, which
together act as a separate agreement in respect of each series trust
established under the master trust deed, and will be confirmed by a written
confirmation.

Principal Payments
      On the closing date, the issuer trustee will pay the currency swap
providers the U.S. dollar proceeds of issue of the Class A-1 notes. In return,
the currency swap providers 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.

      On each distribution date, the issuer trustee will pay to the currency
swap providers 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 providers 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 providers an aggregate 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.

                                       87
<PAGE>

      In return, the currency swap providers will pay to the principal paying
agent on behalf of the issuer trustee amounts in aggregate equal to 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 providers in
respect of the above payment the currency swap providers are not required to
make the corresponding payments to the principal paying agent and, after the
applicable grace period, the currency swap providers may terminate the currency
swaps. The manner of determining whether the issuer trustee will have
sufficient funds to pay the currency swap providers 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 a currency
swap, if not remedied within the applicable grace period, will be an event of
default under the security trust deed.

Termination by a Currency Swap Provider
      A currency swap provider will have the right to terminate the relevant
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;

    .  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 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. In addition, whether or not the currency swap provider can
       terminate the currency swap, following the occurrence of such an
       event, the currency swap provider may transfer the currency swap to
       another counterparty with, in certain circumstances, the consent of
       the standby swap provider, as to which see "Jointly Supported
       Obligations" below, provided that each rating agency has confirmed
       that this will not result in there being a reduction, qualification
       or withdrawal of any credit rating assigned by it to the Class A-1
       notes; and

    .  if an event of default occurs under the security trust deed and the
       security trustee has declared the Class A-1 notes immediately due and
       payable.

Termination by the Issuer Trustee
      The issuer trustee will have the right to terminate a 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 issuer trustee 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;

    .  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 longer 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; and

    .  if an event of default occurs under the security trust deed and the
       security trustee has declared the Class A-1 notes immediately due and
       payable.

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

Termination by the Class A-1 Note Trustee
      If following an event that allows the issuer trustee to terminate a
currency swap the issuer trustee 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 providers do not have:

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

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

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

the currency swap providers must within:

    .  30 Business Days, if the currency swap providers still have a long
       term joint credit rating of at least A- by Standard & Poor's and a
       short term joint credit rating of at least A-1 by Standard & Poor's,
       and a long term joint credit rating of at least A3 by Moody's and a
       long term joint credit rating of at least A- by Fitch; or

    .  5 Business Days, in any other case,

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

    .  if the short term joint credit rating by Standard & Poor's is greater
       than or equal to A-1 or the long term joint credit rating by Standard
       & Poor's is greater than or equal to A- and the long term joint
       credit rating by Fitch is greater than or equal to A-, lodge
       collateral as determined under the currency swap and the credit
       support annex;

    .  enter into an agreement novating the currency swap to a replacement
       counterparty or standby swap provider acceptable to the relevant
       standby swap provider, as to which see "Jointly Supported
       Obligations" below, and 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.

      A currency swap provider may satisfy its obligations following a
withdrawal or downgrade of a credit rating in any of the above manners as it
elects from time to time.

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

Termination Payments
      Upon termination of a 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.

      The termination payment in respect of a 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 a Currency Swap
      If a 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 a 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.

Currency Swap Providers
      The currency swap providers will be Merrill Lynch International
(Australia) Limited and Commonwealth Bank of Australia.

Merrill Lynch International (Australia) Limited
      Merrill Lynch International (Australia) Limited ("MLIA") is a wholly
owned subsidiary of Merrill Lynch & Co. Inc. ("ML&Co."). ML&Co. is a holding

Office of the Secretary.

Transfer by MLIA of Currency Swap
      MLIA may transfer all its rights and obligations as currency swap
provider or standby swap provider to another entity which has the benefit of a
guarantee from ML&Co. provided the rating agencies confirm this will not cause
a reduction, qualification or withdrawal of the credit ratings of the Class A-1
notes. After that transfer, MLIA will have no further obligations under the
currency swap.

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 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 1,100 locations
throughout Australia and internationally.

      Commonwealth Bank has a long term credit rating of AA from Fitch, Aa3
from Moody's and AA- from Standard & Poor's and a short term credit rating of
A-1+ from Standard & Poor's, F1+ from Fitch and P-1 from Moody's.

      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$9.3 billion. Operating profit after
tax, abnormals and outside equity interests for the twelve months to June 30,
1999 was A$1.42 billion.

      On March 10, 2000, Commonwealth Bank and Colonial Limited, previously an
Australian holding company which owned banking, insurance and funds management
businesses, announced their intention to merge, with 7 Commonwealth Bank shares
being offered for each 20 Colonial Limited shares. The merger received final
approval from the Supreme Court of Victoria on May 31, 2000 and was completed
on June 13, 2000.

      Following the merger with Colonial Limited, each of the rating agencies
affirmed the above credit ratings of Commonwealth Bank.

      Commonwealth Bank currently files periodic reports with the Securities
and Exchange Commission pursuant to the Exchange Act. The 1999 Annual Report of
Commonwealth Bank on Form 20-F was filed with the Securities and Exchange
Commission on September 10, 1999. Commonwealth Bank will provide without charge
to each person to

                                       92
<PAGE>

whom this prospectus is delivered, on the request of any such person, a copy of
the Form 20-F referred to above. Written requests should be directed to:
Commonwealth Bank of Australia, 599 Lexington Avenue, New York, NY 10022,
Attention: Executive Vice President and General Manager Americas.

      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."

Transfer by Commonwealth Bank of Currency Swap
      If an event beyond the control of Commonwealth Bank occurs so that it is
impossible for Commonwealth Bank to convert Australian dollars to U.S. dollars
through customary legal channels to fulfill its obligations under its currency
swap, Commonwealth Bank may transfer all its rights and obligations as currency
swap provider to MLIA and may terminate its obligations as standby swap
provider. After that transfer, Commonwealth Bank will have no further
obligations under the currency swap.

Jointly Supported Obligations
      The obligations of each currency swap provider under its currency swap
are separate and several from the obligations of the other currency swap
provider under the other currency swap.

      However, each currency swap provider will also act as a standby swap
provider in respect of the other currency swap provider's currency swap. If a
currency swap provider:

    .  defaults in making a payment in respect of its currency swap, as
       described under "Principal Payments" and "Interest Payments" above;
       or

    .  defaults in meeting its obligations following a downgrade of the
       currency swap providers' joint credit ratings, as described in
       "Currency Swap Provider Downgrade" above,

the issuer trustee must notify the standby swap provider and the standby swap
provider must make good the default within prescribed periods. A remedy of a
payment default must occur on the same day as the due date for the payment
provided that the standby swap provider is notified of the default by the
issuer trustee in the manner required by the relevant currency swap agreement.

      If a standby swap provider is required to make good a default, the
defaulting currency swap provider must take certain actions, including
reimbursing or indemnifying the standby swap provider, in relation to the
default. If the defaulting currency swap provider does not take these actions
within the prescribed periods then the rights and obligations of the defaulting
currency swap provider under its currency swap will automatically transfer to
the standby swap provider.

                                       93
<PAGE>

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 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 such a withholding or deduction. In
that event the issuer trustee or the paying agent, as the case may be, shall
account to the relevant authorities for the amount so required to be withheld
or deducted. Neither the issuer trustee nor any paying agent nor the Class A-1
note trustee 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
principal 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 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,

                                       94
<PAGE>

       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 on any subsequent distribution date at their
then Invested Amounts, subject to the following, together with accrued but
unpaid interest to but excluding the date of redemption. The issuer trustee
may redeem the 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 noteholders and redraw bondholders together.

      However, the manager will not direct the issuer trustee to, and 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 Invested
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, upon becoming aware of the event of default and 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 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, subject to the

                                      95
<PAGE>

following, 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 September 1, 2000; and

    .  the distribution date falling in December 2007.

The issuer trustee may redeem the 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 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. If the issuer trustee, at the direction of the manager, proposes to
exercise its option to redeem the notes and redraw bonds on a distribution date
during or after December 2007 at their Stated Amounts rather than their
Invested Amounts, as described above, but is unable to do so because, following
a meeting of noteholders and redraw bondholders convened under the provisions
of the security trust deed by the manager for this purpose, the noteholders and
redraw bondholders have not approved by an Extraordinary Resolution the
redemption of the notes and redraw bonds at their Stated Amounts, then the
margin for the Class A-1 notes for each accrual period commencing on or after
that distribution date will remain at, or revert to, the margin applying at the
closing date.

      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 December 2031.

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.

                                       96
<PAGE>

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.

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 a Potential Termination Events occurs and:

    .  the issuer trustee determines that the Potential Termination Event
       has or will have an Adverse Effect, upon which it must promptly
       notify the manager, the servicer, the security trustee and the Class
       A-1 note trustee;

    .  the servicer, the issuer trustee and the manager consult and use
       their reasonable endeavours, in consultation with the security
       trustee, the Class A-1 note trustee, and, if necessary, the residual
       unitholder, to amend or vary the terms of the series supplement, any
       other relevant transaction document and the notes and redraw bonds in
       such a way so as to cure the Potential Termination Event or its
       Adverse Effect; and

    .  such consultations do not result in the cure of the Potential
       Termination Event or its Adverse Effect, with the consent of the
       servicer, the issuer trustee, the manager, the security trustee and
       the Class A-1 note trustee, within 60 days of notice being given by
       the issuer trustee as described above.

      If this occurs then the issuer trustee, in consultation with the manager,
must proceed to liquidate the assets of the trust in accordance with 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 realise 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 to a person other than the
seller 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."

                                       97
<PAGE>

      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 endeavours 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.

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." Upon final distribution
being made, the notes will be deemed to be redeemed and discharged in full and
the obligations of the issuer trustee with respect to the payment of principal,
interest or any other amount on the notes will be extinguished.

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
of principal or interest on the Class A-1 note which would have the effect of
reducing the Stated Amount of, and all accrued but unpaid interest on, the
Class A-1 note to zero. 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 by Class A-1 noteholders holding Class A-1 notes
with an Invested Amount of greater than 50% of the aggregate Invested 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 Invested 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 Invested 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, without the consent or sanction of any Class A-1 noteholder,
subject to the 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 or any decision of any court
       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 or any
       decision of any court 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;

                                       99
<PAGE>

    .  and the issuer trustee 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 is obtained of Class A-1
         noteholders owning 75% of the aggregate Invested Amount of the
         Class A-1 notes, excluding notes beneficially owned by the issuer
         trustee or the manager or any person controlling or controlled by
         or under common control with the issuer trustee or the manager.

      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, other than a Payment Modification, 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 trustee, the manager and the Class A-1 note trustee may make
or effect 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, the Class A-1 notes, the master
trust deed so far as it applies to the trust, the series supplement or the
security trust deed which modifies:

    .  the amount, timing, currency or manner of payment of principal or
       interest in respect of the Class A-1 Notes, including, without
       limitation, any modification to the Stated Amount, Invested Amount,
       interest rate or maturity date of the Class A-1 notes or the orders
       of payment of the proceeds of the trust assets under the series
       supplement, the Class A-1 notes or the security trust deed or which
       would impair rights of Class A-1 Noteholders to institute suit for
       enforcement of such payment;

    .  the manner of determining whether Class A-1 noteholders owning 75% of
       the aggregate Invested Amount 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 to reduce the percentage of the aggregate
       Invested Amount of the Class A-1 notes required for such a consent or
       direction;

    .  the provision of the security trust deed that prohibits the issuer
       trustee from creating or permitting to exist any security interest,
       other than the Prior Interest, over the assets of the trust; or,

                                      100
<PAGE>

    .  the requirements for altering, adding to or revoking any provision of
       the Class A-1 note trust deed, the Class A-1 notes, the master trust
       deed so far as it applies to the trust, the series supplement or the
       security trust deed.

      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 the Business Day immediately prior to each distribution date, the
manager will, in respect of the accrual period ending before that distribution
date, deliver to the principal paying agent, Class A-1 the note trustee, the
issuer trustee and 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 seller advances made during that quarterly
       collection period;

    .  the redraw shortfall, if any;

    .  the income shortfall, if any;

    .  the liquidity facility advances, if any, for that distribution date,
       together with all liquidity facility advances in relation to the
       preceding determination date;

    .  the Available Principal Amount;

    .  the Principal Collections;

    .  the Standby Redraw Facility Advance;

    .  the Redraw Bond Amount;

    .  the principal charge-off in relation to the preceding determination
       date;

    .  the Other Principal Amounts;

    .  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 principal charge-offs for each class of notes and the standby
       redraw facility principal;

    .  the Principal Charge-Off Reimbursement for each class of notes and
       the standby redraw facility principal;

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

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

                                      101
<PAGE>

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

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

    .  delinquency, mortgagee in possession 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 , P-1 from Moody's and A-1+ from Standard & Poor's, at its office at 48
Martin Place, Sydney, NSW 2000, Australia. The

                                      102
<PAGE>

collections account shall be opened by the 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. In
addition, if the Eligible Depository has a short term credit rating of A-1 from
Standard & Poor's the sum of the balance of the collections account and the
value of Authorized Short-Term Investments with a short term rating of A-1 by
Standard & Poor's must not exceed 20% of the aggregate Invested Amount of all
notes.

      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 in the opinion of the
       issuer trustee 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;

                                      103
<PAGE>

    .  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

    .  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 seller, the manager or the issuer trustee may only amend, add to or
revoke any provision of the series supplement in accordance with the master
trust deed. Any amendment, addition or revocation that effects a Payment
Modification may only be made with the consent of each Class A-1 noteholder.

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.

                                      104
<PAGE>

      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 endeavours to carry on and conduct its business in so far as it
relates to the master trust deed and the series 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.

                                      105
<PAGE>

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 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 payable in arrears on
each 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 Days' 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.

      If the issuer trustee becomes liable to remit to a governmental agency an
additional amount of Australian goods and services tax or is otherwise
disadvantaged by a change in the Australian goods and services tax legislation
in connection with the trust, the issuer trustee will not be entitled to any
reimbursement from the assets of the trust. However, the fees payable to the
issuer trustee may be adjusted, in accordance with the series supplement.

      At any time within 12 months after the abolition of or a change in the
goods and services tax laws becomes effective, the issuer trustee or the
manager may, by written notice to the other, require negotiations to commence
to adjust the fees payable to the issuer trustee so that it is not economically
advantaged or disadvantaged by the effect of the change in the goods and
services tax. Any adjustment to fees will be subject to written confirmation
from the rating agencies that the adjustment will not result in a reduction,
qualification or withdrawal of the credit ratings then assigned to the notes.

      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

                                      106
<PAGE>

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 endeavours to appoint a qualified
substitute issuer trustee who is approved by the ratings agencies of all the
Medallion Programme trusts 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.

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.

                                      107

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 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 Programme 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 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 Australian 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 endeavours 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 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 management fee and a quarterly
arranging fee payable in arrears on each distribution date.

      The management fee payable to the manager by the issuer trustee out of
the available income amount may be varied as agreed between the issuer trustee
and the manager provided that each rating agency must be given 3 Business Days'
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.

      If the manager becomes liable to remit to a governmental agency an amount
of Australian goods and services tax in connection with the trust, the manager
will pay goods

                                      109
<PAGE>

and services tax on its own account and will not be entitled to any
reimbursement from the assets of the trust. However, the fees payable to the
manager may be adjusted, in accordance with the series supplement.

      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
from the date of the manager's retirement.

      Until a substitute manager is appointed, the issuer trustee must act as
manager and will be entitled to receive the manager's fee.

Limitation of Manager's Liability
      The manager is not personally liable to indemnify the issuer trustee or
to make any payments to any other person in relation to the trust except where
arising from any fraud, negligence, wilful default or breach of duty by it in
its capacity as manager of the trust. A 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 limitation that the manager will not
be liable for any loss, costs, liabilities or expenses:

    .  arising out of the exercise or non-exercise of its discretions under
       any transaction document or otherwise in relation to the trust;

    .  arising out of the exercise or non-exercise of a discretion on the
       part of the issuer trustee, the seller or the servicer or any act or
       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 or any of its assets. In particular, no noteholder or redraw bondholder
is entitled to:

    .  an interest in any particular part of the trust or any asset of 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
       or powers of the seller, the servicer, the manager or the issuer
       trustee in their dealings with the trust or any assets of the trust;

    .  attend meetings or take part in or consent to any action concerning
       any property or corporation in which the issuer trustee has an
       interest;

    .  exercise any rights, powers or privileges in respect of any asset of
       the trust;

    .  lodge a caveat or other notice forbidding the registration of any
       person as transferee or proprietor of or any instrument affecting any
       asset of the trust or claiming any estate or interest in any asset of
       the trust;

    .  negotiate or communicate in any way with any borrower or security
       provider under any housing loan assigned to the issuer trustee or
       with any person providing a support facility to the issuer trustee;

    .  seek to wind up or terminate the trust;

    .  seek to remove the servicer, manager or issuer trustee;

    .  interfere in any way with the trust;

    .  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 and the
       security trustee to comply with their respective obligations 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
       personal capacity, except to the extent of fraud, negligence or
       wilful default on the part of the issuer trustee or the manager
       respectively; or

    .  have any recourse whatsoever to the seller or to the servicer in
       respect of a breach by the seller or the servicer of their respective
       obligations and duties under the series supplement.

The Class A-1 Note Trustee

Appointment of Class A-1 Note Trustee
      The Bank of New York, New York Branch will serve as the Class A-1 note
trustee. The Bank of New York is a banking corporation duly organized and
existing under the laws

                                      111
<PAGE>

of New York. The corporate trust office of the Class A-1 note trustee
responsible for the administration of the Class A-1 note trustee's obligations
in relation to the trust is located at 101 Barclay Street, 21W, New York, New
York 10286.

Class A-1 Note Trustee's Fees and Expenses
      The issuer trustee must pay the Class A-1 note trustee's fees out of its
personal funds, other than fees in respect of any additional duties outside the
scope of the Class A-1 note trustee's normal duties under the transaction
documents.

Delegation by Class A-1 Note Trustee
      The Class A-1 note trustee will be entitled to delegate its duties,
powers, authorities, trusts and discretions under the Class A-1 note trust deed
to any related company of the Class A-1 note trustee or to any other person in
accordance with the Class A-1 note trust deed or as agreed by the manager.

Indemnity of Class A-1 Note Trustee
      The Class A-1 note trustee will be entitled to be indemnified from the
assets of the trust against all liability, expense, costs, charges, taxes and
stamp duties other than general overhead costs and expenses properly incurred
by the Class A-1 note trustee, or its properly appointed agents or delegates,
in the performance of its obligations under the Class A-1 note trust deed or
any other transaction document.

      However, the Class A-1 note trustee will not be entitled to be
indemnified against any liability for breach of trust or any liability which by
virtue of any rule of law would otherwise attach to it in respect of fraud or
wilful default of which it may be guilty in relation to its duties under the
Class A-1 note trust deed.

Qualifications of Class A-1 Note Trustee
      The Class A-1 note trustee is, and will at all times be, a corporation or
association, organized and doing business under the laws of the United States
of America, any individual state or the District of Columbia, authorized under
those laws to exercise corporate trust powers, having a combined capital of
US$50,000,000, as set forth in its most recent published annual report of
condition, and subject to supervision or examination by federal or state
authority. The Class A-1 note trustee may also, if permitted by the Securities
and Exchange Commission, be organized under the laws of a jurisdiction other
than the United States, provided that it is authorized under such laws to
exercise corporate trust powers and is subject to examination by authority of
such jurisdictions substantially equivalent to the supervision or examination
applicable to a trustee in the United States.

Removal of Class A-1 Note Trustee
      The Class A-1 note trustee will retire as note trustee if:

    .  an Insolvency Event occurs in relation to the note trustee in its
       personal capacity or in respect of its personal assets and not in its
       capacity as trustee of any trust or in respect of any assets it holds
       as trustee;

                                      112
<PAGE>

    .  it ceases to carry on business;

    .  it ceases to be an Eligible Trust Corporation;

    .  it is so directed by the Class A-1 noteholders holding no less than
       75% of the aggregate Invested Amount of the Class A-1 notes;

    .  when required to do so by the manager or the issuer trustee by notice
       in writing, it fails or neglects within 20 Business Days after
       receipt of such notice to carry out or satisfy any material duty
       imposed on it by the note trust deed or any transaction document; or

    .  there is a change in ownership of 50% or more of the issued equity
       share capital of the Class A-1 note trustee from the position as at
       the date of the Class A-1 note trust deed or effective control of the
       Class A-1 note trustee alters from the position as at the date of the
       Class A-1 note trust deed unless in either case approved by the
       manager, whose approval must not be unreasonably withheld.

      If any of these events occurs and the Class A-1 note trustee refuses to
retire, the manager may remove the Class A-1 note trustee from office
immediately by notice in writing. On the retirement or removal of the Class A-1
note trustee:

    .  the manager must promptly notify the rating agencies; and

    .  subject to any approval required by law, the manager must use
       reasonable endeavours to appoint in writing some other Eligible Trust
       Corporation approved by the rating agencies to be the substitute
       Class A-1 note trustee.

Class A-1 Note Trustee May Retire
      The Class A-1 note trustee may retire at any time on 3 months', or such
lesser period as the manager, the issuer trustee and the Class A-1 note trustee
agree, notice in writing to the issuer trustee, the manager and the rating
agencies, without giving any reason and without being responsible for any
liabilities incurred by reason of its retirement provided that the period of
notice may not expire within 30 days before a distribution date. Upon
retirement the Class A-1 note trustee, subject to any approval required by law,
may appoint in writing any other Eligible Trust Corporation approved by the
rating agencies and the manager, which approval must not be unreasonably
withheld by the manager, as Class A-1 note trustee. If the Class A-1 note
trustee does not propose a replacement at least one month prior to its proposed
retirement, the manager may appoint a substitute Class A-1 note trustee, which
must be an Eligible Trust Corporation approved by the rating agencies.

Appointment by Class A-1 Noteholders
      No retirement or removal of the Class A-1 note trustee will be effective
until a substitute Class A-1 note trustee has been appointed.

      If a substitute Class A-1 note trustee has not been appointed at a time
when the position of Class A-1 note trustee would, but for the foregoing
requirement, become vacant, the issuer trustee must promptly advise the Class
A-1 noteholders. A special majority of

                                      113
<PAGE>

Class A-1 noteholders, being Class A-1 noteholders who hold not less than 75%
of the aggregate Invested Amount of all Class A-1 notes, may appoint an
Eligible Trust Corporation to act as Class A-1 note trustee.

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 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 Secured Moneys owing to the noteholders, the redraw bondholders, the
servicer, the Class A-1 note trustee in its personal capacity and for and on
behalf of the Class A-1 noteholders, each 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 any other transaction document and the manager has agreed not to direct the
issuer trustee to take any such actions. If, however, the issuer trustee
disposes of any of the trust assets, including any housing loan, other than in
accordance with the master trust deed, the series supplement or any other
transaction document, the person acquiring the property may nevertheless 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.

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

                                      114
<PAGE>

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
       Programme trusts in accordance with the master trust deed;

    .  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

                                      115
<PAGE>

       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 of the discovery thereof, 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 any legislation that imposes a tax)
       requiring any person obliged or authorised to pay money to the issuer
       trustee to instead pay such money to the Commissioner in respect of
       any tax or any fines and costs imposed on the issuer trustee; 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
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 and,
in any event, within 2 business days, 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.

                                      116
<PAGE>

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$10 of
Secured Moneys owing to it, converted, in the case of the Class A-1
noteholders, to Australian dollars at either the A$ Exchange Rate or the spot
rate used for the calculation of amounts payable on the early termination of
the currency swap, whichever produces the lowest amount in Australian dollars.

      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
      Upon a vote at a meeting of Voting Secured Creditors called following an
event of default under the security trust deed, or by a resolution in writing
signed by all Voting Secured Creditors, the Voting Secured Creditors may 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 realise the assets of the trust and otherwise enforce the
       charge; or

    .  take any other action as the Voting Secured Creditors may specify in
       the terms of such Extraordinary Resolution.

      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.

                                      117
<PAGE>

      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, or any event which, with the giving of notice or
lapse of time or both, would constitute 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 any stock exchange or listing authority 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 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 Invested Amount of the Class A-1 notes.

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

                                      118
<PAGE>

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 before
or during the meeting 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 and subject to the application of proceeds of the
termination of the currency swap as described in the next paragraph:

    .  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 and any liabilities, losses, costs,
       claims, expenses, actions, damages, demands, charges, stamp duties
       and other taxes due to the security trustee, the Class A-1 note
       trustee or any 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;

                                      119
<PAGE>

    .  fifth, to pay the Class A-1 noteholders the proceeds, if any, of any
       termination payment received from a 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 by the liquidity facility
       provider and any unpaid interest on that cash collateral;

    .  seventh, to pay rateably:

      .   the seller any unpaid Accrued Interest Adjustment and the then
         seller deposit; and

      .  the fixed rate swap provider and the basis swap provider amounts
         in respect of collateral or prepayments owing under the fixed rate
         swap or basis swap;

    .  eighth, to pay rateably:

      .  the Class A noteholders and redraw bondholders all other Secured
         Moneys owing in relation to the Class A notes and redraw bonds.
         For this purpose, the Secured Moneys owing in respect of the Class
         A notes and redraw bonds will be calculated based on a principal
         component of their Stated Amount and in the case 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 used for the
         calculation of any termination payment 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
         provided that for this purpose the Secured Moneys owing in respect
         of the principal component of the standby redraw facility will
         exclude unreimbursed principal charge-offs;

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

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

    .  ninth, to pay rateably to the Class A noteholders, the redraw
       bondholders and the standby redraw facility provider all unreimbursed
       principal charge-offs constituting remaining Secured Moneys owing in
       respect of the Class A notes, the redraw bonds and the standby redraw
       facility. For this purpose, the Secured Moneys 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 used for
       the calculation of any termination payment upon the termination of
       the currency

                                      120
<PAGE>

       swap, as determined by the security trustee in each case, which ever
       rate produces the lesser amount of Australian dollars;

    .  tenth, if there are still Secured Moneys owing in respect of the
       Class A-1 notes, after the application of the preceding paragraphs,
       to pay the remaining Secured Moneys owing in relation to the Class A-
       1 notes;

    .  eleventh, equally to the Class B noteholders;

    .  twelfth, 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;

    .  thirteenth, 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

    .  fourteenth, 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.

Any proceeds from the termination of the currency swap must be applied first in
accordance with the fifth bullet point above, with any remaining proceeds to be
applied in accordance with the order of priority set out above.

      Payments to Class A-1 noteholders will be effected in US$ obtained by the
security trustee either from a US$ termination payment received from a currency
swap provider or by converting the A$ available for such payments, based on the
priority set out above, at the spot exchange rate.

      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 must retire if:

    .  an Insolvency Event occurs with respect to it;

    .  it ceases to carry on business;

                                      121
<PAGE>

    .  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 14
       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 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.

      The security trustee may retire on 3 months' notice. If the security
trustee retires, it may appoint an authorized trustee corporation to act in its
place with the approval of the manager, which must not be unreasonably
withheld, and the rating agencies. If the security trustee does not propose a
replacement by one month prior to the date of its retirement, the manager is
entitled to appoint a substitute security trustee which must be an authorized
trustee corporation approved by 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 security 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
       governmental agency or any decision of any court 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 or any decision of any court,
       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; or

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

                                      122
<PAGE>

      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 Invested Amount 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 effects or
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.

redraw facility, adjusted for principal charge-offs and principal charge-off
reimbursements as described below, at the Bank Bill Rate plus a margin,
calculated on the number of days elapsed and a 365 day year. Interest is
payable quarterly in arrears on each distribution date to the extent that funds
are available for this purpose in accordance with the series supplement. Unpaid

standby redraw facility agreement. The term may be renewed at the option of
the standby redraw facility provider if it receives a request for an extension
from the manager 60 days prior to the scheduled termination. If the standby
redraw facility provider agrees to an extension, the term of the standby

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, subject to applicable
laws, adjust the rates at which interest set-off benefits are calculated under
the mortgage interest saver accounts to rates which produce an amount of income
which is sufficient to ensure that the issuer trustee has sufficient funds to
comply with its obligations under the transaction documents as they fall due.
If rates at which such interest set-off benefits are calculated have been
reduced to zero and the amount of income produced by the reduction of the rates
on the mortgage interest saver accounts is not sufficient, 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 Australian
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 or, when the seller is
       the servicer, F1 from Fitch, 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 no lower than A-1 from
       Standard & Poor's, P-1 from Moody's and F1 from Fitch, 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

                                      130
<PAGE>

    .  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, 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.

     If collections are retained by the servicer in accordance with the first
two paragraphs above, the servicer may retain any interest and other income
derived from those collections but 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, payable in arrears on each
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.

     If the servicer becomes liable to remit to a governmental agency an
amount of Australian goods and services tax in connection with the trust, the
servicer will pay goods and services tax on its own account and will not be
entitled to any reimbursement from the assets of the trust. However, the fees
payable to the servicer may be adjusted, in accordance with the series
supplement.

     The manager and the servicer may from time to time agree to adjust the
servicing fee subject to written confirmation from the rating agencies that
the adjustment will not result in a reduction, qualification or withdrawal of
the credit ratings then assigned by them to the notes.

     The servicer must pay from its own funds all expenses incurred in
connection with servicing the housing loans except for certain specified
expenses in connection with, amongst other things, 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

                                      131
<PAGE>

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;

    .  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 adjust the rates on the mortgage interest saver
       accounts or 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

                                      132
<PAGE>

    .  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, acting reasonably. 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 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, as the case may be, it must in respect of set-off risk in
relation to the trust:

    .  deposit or maintain in an account, which may be the collections
       account provided it is held with an entity with a short term credit
       rating of A-1+ by Standard & Poor's, 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 the amount determined in accordance with
       the series supplement or otherwise agreed by Moody's or Fitch. 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.

      The seller deposit will be calculated by reference to the balances of
accounts held by borrowers with the seller where the terms of that borrower's
housing loan do not include a provision by which a borrower agrees to make all
payments without set-off or counterclaim,

                                      133
<PAGE>

unless prohibited by law. If all the housing loans include such a provision the
seller will not be required to make any deposit and any existing seller deposit
may be repaid.

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.

Audit
      The seller will be audited by the auditor of the trust 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

                                      134
<PAGE>

    .  the long term debt rating of the seller is downgraded below BBB by
       Standard & Poor's or Fitch 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 other than a Servicer Default referred to in the next bullet
       point; or

    .  the issuer trustee considers in good faith that a Servicer Default
       has occurred as a result of a breach of certain of the servicer's
       obligations which has or will have an Adverse Effect which is not
       remedied within the required period, and the issuer trustee serves a
       notice on the servicer identifying the reasons why it believes that
       has occurred,

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
deposited with a solicitor (acting on behalf of the servicer), a land titles
office, a stamp duty office or 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.

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 September 1, 2000 has occurred or is expected to
       occur on or before the next distribution date; or

                                      135
<PAGE>

    .  both of the following events occur:

      .  the next distribution date is the distribution date falling in
         December, 2007 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 September 1, 2000.

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 Invested 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."

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

                                      136
<PAGE>

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 a 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 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.

                                      137
<PAGE>

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 are sent to the
borrower. 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 judgment 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 insurers.

      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.

      Loan losses for each period are net of recoveries including claims under
mortgage insurance policies in respect of loans with an LTV of greater than
80%. Percentage losses are calculated based on the average outstanding balance
for the period and annualized for the half year ending December 31, 1999.

      The servicer does not have available details of its foreclosure
experience. It is the servicer's policy on enforcement of a housing loan to
enter into possession of the mortgaged property as mortgagee in possession
rather than to foreclose on the mortgage. See "The Servicer--Collection and
Enforcement Process". The servicer has undertaken to collect details of its
mortgagee in possession experience for the housing loans in the pool on an
ongoing basis.

      There can be no assurance that the delinquency and loss experience with
respect to the housing loans comprising the housing loan pool will correspond
to the delinquency and loss experience of the servicer's mortgage portfolio set
forth in the foregoing table. The statistics shown in the preceding table
represent the delinquency and loss experience for the total residential
mortgage portfolio for each of the years presented, whereas the aggregate
delinquency and loss experience on the housing loans will depend on the results
obtained over the life of the housing loan pool. 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

                                      139
<PAGE>

market should experience an overall decline in property values such that the
principal balances of the housing loans comprising the housing loan pool become
equal to or greater than the value of the related mortgaged properties, the
actual rates of delinquencies and losses 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 housing loan pool. You should note that
Australia experienced a period of relatively low and stable interest rates
during the period covered in the preceding tables. The Reserve Bank of
Australia has increased interest rates by 1.50% since October, 1999. If
interest rates were to rise significantly, 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;

                                      140
<PAGE>

    .  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.

      The prepayment amounts described above are reduced by repayment to the
seller of redraws and further advances as described in "Commonwealth Bank
Residential Loan Programme--Special Features of the Housing Loans--Redraws and
Further 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

                                      141
<PAGE>

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 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 September 1, 2000;

    .  closing date for the notes is September 18, 2000;

    .  a weighted average interest rate on housing loans of 7.235%;

    .  a weighted average remaining term to maturity of housing loans of 296
       months;

    .  payments on the notes are made on the quarterly payment date,
       regardless of the day on which payment actually occurs, commencing in
       December 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 March, 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 September 1, 2000,
       with no defaults;

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

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

                                      142
<PAGE>

    .  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$0.5897 = 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 months 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, expressing the result in years, and
       rounding to three decimal places.

    The source of the information in the following table is Commonwealth
       Bank.

      The net proceeds from the sale of the Class A-1 notes, after being
exchanged pursuant to the currency swap, will amount to A$   and will be used
by the issuer trustee, along with the proceeds from the issue of the Class A-2

                       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,

                                      145
<PAGE>

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.

      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 are 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 or will have rights
enforceable against any assignee of a member. This charge, or those rights as a
matter of practice, 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.

                                      146
<PAGE>

      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 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.

                                      147
<PAGE>

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

                                      148

      A mortgagee's ability to call in all amounts under a housing loan or
enforce a mortgage which is subject to the Australian 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.

                                      149
<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.

                                      150
<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 Australian 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

                                      151
<PAGE>

timing or amount of interest or principal payments or repayments to you under
the Class A-1 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 (the "Code"), 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.

                                      152
<PAGE>

      Additionally, the discussion regarding the Class A-1 notes 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.

      We will agree, and if you purchase Class A-1 notes, you will agree by
your purchase of the notes, to treat the Class A-1 notes as debt for United
States Federal, State and local income and franchise tax purposes. In the
opinion of Mayer, Brown & Platt, for United States Federal income tax purposes,
the Class A-1 notes will be characterized as debt of the issuer trustee. Each
noteholder, by the acceptance of an offered note, will agree to treat the Class
A-1 notes as indebtedness for Federal income tax purposes.

General
      Original Issue Discount, Indexed Securities, etc. The discussion below
assumes that all payments on the Class A-1 notes are denominated in U.S.
dollars, and that the offered notes are not indexed securities or strip notes.
Additionally, the discussion assumes that the interest formula for the Class A-
1 notes meets the requirements for "qualified stated interest" under Treasury
regulations, called the "OID Regulations," relating to original issue discount,
or "OID." This discussion assumes that any original issue discount on the Class
A-1 notes is a de minimis amount, within the meaning of the OID Regulations.
Under the OID Regulations, the offered notes will have original issue discount
to the extent the principal amount of the Class A-1 notes exceeds their issue
price. Further, if the Class A-1 notes have any original issue discount, it
will be de minimis if it is less than 1/4% of the principal amount of the
offered notes multiplied by the number of full years included in their term.

Interest Income on the Class A-1 Notes
      Based on the above assumptions, except as discussed below, the Class A-1
notes will not be considered issued with original issue discount. If you buy
Class A-1 notes, you will be required to report as ordinary interest income the
stated interest on the notes when received or accrued in accordance with your
method of tax accounting. Under the OID Regulations, if you hold a note issued
with a de minimis amount of original issue discount,

                                      153
<PAGE>

you must include this original issue discount in income, on a pro rata basis,
as principal payments are made on the note. If you purchase a note for more or
less than its principal amount, you will generally be subject, respectively, to
the premium amortization or market discount rules of the Code, discussed below.

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.

      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.

                                      154
<PAGE>

      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.

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.

                                      155
<PAGE>

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 taxes. 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.

Tax Consequences to Foreign Noteholders
      If interest paid (or accrued) to a noteholder who is a nonresident alien,
foreign corporation or other non-United States person, a "foreign person," is
not effectively connected with the conduct of a trade or business within the
United States by the foreign person, the interest should generally not be
subject to U.S. income tax or withholding tax as such interest should generally
not be treated as U.S. source income. In the event such interest is treated as
U.S. source income, the interest generally will be considered "portfolio
interest," and generally will not be subject to United States federal income
tax and withholding tax, as long as the foreign person (1) is not actually or
constructively a "10 percent shareholder" of the issuer trustee or a
"controlled foreign corporation" with respect to which the issuer trustee is a
"related person" within the meaning of the Code, and (2) provides an
appropriate statement, signed under penalties of perjury, certifying that the
beneficial owner of the note is a foreign person and providing that foreign
person's name and address. If the information provided in this statement
changes, the foreign person must so inform the issuer trustee within 30 days of
such change. If such interest were not portfolio interest or if applicable
certification requirements were not satisfied, then it would be subject to
United States Federal income and withholding tax at a rate of 30 percent unless
reduced or eliminated pursuant to an applicable tax treaty. The IRS has amended
the transition period relating to new regulations governing backup withholding
and information reporting requirements. Withholding certificates or statements
that are valid on December 31, 1999, may be treated as valid until the earlier
of their expiration or December 31, 2000. All existing certificates or
statements will cease to be effective after December 31, 2000.

                                      156
<PAGE>

      Any capital gain realized on the sale, redemption, retirement or other
taxable disposition of an offered note by a foreign person will be exempt from
United States federal income and withholding tax, provided that (1) the gain is
not effectively connected with the conduct of a trade or business in the United
States by the foreign person, and (2) in the case of a foreign individual, the
foreign person is not present in the United States for 183 days or more in the
taxable year.

      If the interest, gain or income on a Class A-1 note held by a foreign
person is effectively connected with the conduct of a trade or business in the
United States by the foreign person, the holder (although exempt from the
withholding tax previously discussed if an appropriate statement is furnished)
generally will be subject to United States Federal income tax on the interest,
gain or income at regular United States Federal Income tax rates. In addition,
if the foreign person is a foreign corporation, it may be subject to a branch
profits tax equal to 30 percent of its "effectively connected earnings and
profits" within the meaning of the Code for the taxable year, as adjusted for
certain items, unless it qualifies for a lower rate under an applicable tax
treaty.

                             Australian Tax Matters

      The following statements with respect to Australian taxation are the
material tax consequences to the 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.

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.

      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.

                                      157
<PAGE>

      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, its associated companies, 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 the
associates of Perpetual Trustee Company Limited, 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 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.

If a Class A-1 noteholder is an Australian resident withholding tax of 48.5%
must be deducted, unless that Class A-1 noteholder supplies the issuer trustee
with its Australian Business Number or Tax File Number.

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

                                      158
<PAGE>

    .  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.

Goods and Services Tax
      From July 1, 2000, a goods and services tax is 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
that it received 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 have to remit goods and
       services tax on the supply and can obtain input tax credits for goods
       and services taxes included in the consideration provided for
       acquisitions relating to the making of this supply; or

    .  "input taxed," which includes financial supplies, the issuer trustee
       does not have to remit goods and services tax on the supply, but will
       not be able to claim input tax credits for goods and services tax
       included in any expenses in making this supply, unless the expenses
       are eligible for a reduced input tax credit.

                                      159
<PAGE>

      The services which are provided to the issuer trustee are expected to be
taxable supplies for goods and services tax purposes. Where this is the case,
it will be the service provider who is liable to pay goods and services tax in
respect of that supply. The service provider must rely on a contractual
provision to recoup the amount of that goods and services tax from the issuer
trustee. Under the series supplement, the issuer trustee's fee will only be
able to be increased by reference to the issuer trustee's 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 be restricted in its ability to claim 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.

      However, the issuer trustee may be entitled to a reduced input tax credit
for some of the supplies made to the issuer trustee by service providers where
the acquisition relates to the making of financial supplies. Where available,
the amount of the reduced input tax credit is currently 75% of the GST which is
payable by the service provider on the taxable supplies made to the issuer
trustee. The availability of reduced input tax credits will reduce the extent
to which the expenses of the trust will increase.

      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.

      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

                                      160
<PAGE>

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 borrower has undertaken substantial renovation of the property;
       or

    .  the mortgaged property has not been used predominantly as a
       residence.

      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.

Tax Reform Proposals
      The Australian federal government proposes to reform business taxation as
part of its current tax reform programme. The committee appointed to consult
with business on the reform of business taxation, the Review of Business
Taxation, released its final report together with draft legislation in respect
of certain aspects of the report by way of a press release on September 21,
1999. In addition, the federal government released its second response to the
report on November 11, 1999.

      There are several measures contained within the final report of the
Review of Business Taxation and, more importantly, within the federal
government responses which, if enacted in their current form, will impact upon
the tax treatment of the trust.

      In particular, the federal government reaffirmed its proposal for trusts
to be taxed in the same manner as companies (this reform was initially proposed
as part of the federal government's tax reform package released in August
1998). However, the new taxation of entities regime will not commence until
July 1, 2001 (with some exceptions which should not be relevant to the trust).

      The proposal for the taxation of trusts like companies, if enacted in the
form proposed, could significantly impact upon the tax treatment of the trust.
However, the proposal is still the subject of extensive review and debate and
may not be enacted in its current form. In addition, if it is enacted, it is
not clear whether an exemption will be granted for securitization vehicles such
as the trust.

      At this point it is anticipated that the new regime will commence on the
announced date on July 1, 2001. While no assurance can be given regarding any
changes to the

                                      161
<PAGE>

announced proposals, in line with past practice in relation to tax reform, it
would be anticipated that any variations from the announced measures will take
effect only from the date of announcement.

      If the trust is taxed as a company, it is likely that the trust will
become liable to pay tax based on a calculation of the taxable income of the
trust, and that distributions to the residual unitholder will be assessable in
accordance with a "profits first" rule. When paid out of after-tax profits, the
residual unitholder may be entitled to a credit against its own tax liability
referable to the tax paid by the trust. The announced entity tax rate that will
apply from July 1, 2001 is 30%.

      The amount of the tax will be based on the net income of the trust after
deduction of expenses, including interest payable to noteholders, and will be a
first priority allocation from the Available Income Amount. It is expected that
if such tax is payable, it will reduce the amount distributed to the residual
unitholder with no overall material effect on the position of the Class A-1
noteholders. For further details on the priority of tax payments see
"Description of the Class A-1 Notes--Distribution of the Available Income
Amount".

      Following recommendations by the Review of Business Taxation, the
Australian Government is presently considering a withholding tax regime
relating to Australian source income, and gains on the disposal of assets
subject to Australian tax, derived by non-residents without a permanent
establishment in Australia. If introduced, the regime will apply only to
amounts outside existing withholding taxes where non-residents are currently
subject to Australian taxation. No announcement has been made concerning the
details of the measures or their implementation date.

      Each of the master trust deed, the series supplement, the security trust
deed and the Class A-1 note trust deed may be amended in certain circumstances
including where this is appropriate or expedient as a consequence of any
amendment to the tax laws. This power may be exercised with regard to the
implementation of the tax reform proposals depending upon their impact on the
trust.

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 Commonwealth Bank of Australia, 599
Lexington Avenue, New York, New York 10022, 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;

    .  the Taliban, also called the Islamic Emirate of Afghanistan, or any
       undertaking owned or controlled, directly or indirectly, by the
       Taliban; or

    .  the National Union for the Total Independence of Angola (UNITA) or
       senior officials, or adult members of the immediate families of
       senior officials of UNITA.

                              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 of 1974
("ERISA") and Section 4975 of the Internal Revenue Code prohibit a pension,
profit-sharing or other employee benefit plan, as well as individual retirement
accounts and certain types of Keogh plans and any entity deemed to hold the
"plan assets" of the foregoing (each, a "Benefit Plan") from engaging in
certain transactions with persons that are "parties in interest" under ERISA or
"disqualified persons" under the Code with respect to 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 imposes certain duties on fiduciaries of a Benefit Plan
subject to ERISA including those of loyalty and prudence.

      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 is no specific guidance in the regulation regarding whether a
principal charge-off feature under the circumstances described herein

                                      164
<PAGE>

would constitute a "substantial equity feature", the regulation does state that
an instrument will not fail to be treated as indebtedness merely because it has
certain equity features, such as additional variable interest or conversion
rights, that are incidental to the instrument's primary fixed obligation.
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 not be treated as an
equity interest for purposes of the regulation. The debt characterization of
the Class A-1 notes could change after their initial issuance (i.e. they could
be treated as equity) if the trust incurs losses or the rating of the Class A-1
notes changes.

      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 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."

There can be no assurance that any of these, or any other exemption, will be
available with respect to any transaction involving the Class A-1 notes. 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 or any
substantially similar applicable law.

      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 but may be subject to state or other laws
that are substantially similar to ERISA or the Code.

      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. The issuance of the Class B notes will be conditioned on obtaining a
rating of AA- by Standard & Poor's, and AA by Fitch. 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,

                                      166
<PAGE>

the availability of the Liquidity Facility, the creditworthiness of the swap
providers and the mortgage insurer. None of the rating agencies have been
involved in the preparation of this prospectus.

      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;

    .  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.

                        Listing and General Information

Listing
      An application has been made to the Financial Services Authority in its
capacity as competent authority under the Financial Services Act 1986 (the "UK
Listing Authority") to admit the Class A-1 notes to the official list of the UK
Listing Authority (the "Official List") and to the London Stock Exchange
Limited (the "London Stock Exchange") for the Class A-1 notes to be admitted to
trading on the London Stock Exchange's market for listed securities. This
prospectus, including Appendix I, constitutes listing particulars with regard
to the issuer trustee and the Class A-1 notes, in accordance with the listing
rules made under Part IV of the Financial Services Act 1986. Copies of the
prospectus have been delivered to the Registrar of Companies in England and
Wales for registration in accordance with Section 149 of the Financial Services
Act 1986.

      The admission of the Class A-1 notes to the Official List and their
admission to trading on the London Stock Exchange will be expressed as a
percentage of their principal amount, exclusive of accrued interest. It is
expected that admission of the Class A-1 notes to the Official List will be
granted and the Class A-1 notes will be admitted to trading on the London Stock
Exchange on or about September  , 2000, subject to the issuance of the Class A-
1 notes. The Class A-1 notes will be issued in the form of one or more book-
entry notes.

      In May 1998, the European Commission presented to the Council of
Ministers of the European Union a proposal to oblige Member States to adopt
either a "withholding tax system" or an "information reporting system" in
relation to interest, discounts and premiums. It is unclear whether this
proposal will be adopted, and if it is adopted, whether it will be adopted in
its current form. The "withholding tax system" would require a paying agent
established in a Member State to withhold tax at a minimum rate of 20 percent
from any interest, discount or premium paid to an individual resident in
another Member State who is the beneficial owner thereof, unless such an
individual presents a certificate obtained from the tax authorities of the
Member State in which he is resident confirming that those authorities are
aware of the payment due to that individual. The "information reporting system"
would require a Member State to supply, to the other Member States, details of
any payment of interest, discount or premium made by paying agents within its
jurisdiction to an individual resident in another Member State who is the
beneficial owner thereof. For these purposes, the term "paying agent" is widely
defined and includes an agent who collects interest, discounts or premiums on
behalf of an individual beneficially entitled thereto.

Authorization
      The issuer trustee has obtained all necessary consents, approvals and
authorizations in connection with the issue and performance of the Class A-1
notes. The issue of the Class A-1 notes has been authorized by the resolutions
of the board of directors of Perpetual Trustee Company Limited passed on
2000.

  4.2 Title

      Title to the Class A-1 Notes will only be shown on, and will only pass by
registration in, the register (the "Class A-1 Note Register") maintained by the
Class A-1 Note Registrar in accordance with the Agency Agreement. Class A-1

authorised denominations and a like Invested Amount (as defined in Condition
6.4), upon the surrender of the Class A-1 Notes to be transferred or exchanged
duly endorsed with or accompanied by a written instrument of transfer and

Class A-1 Notes or for a period, not exceeding 30 days, specified by the Class
A-1 Note Trustee prior to any meeting, which includes Class A-1 Noteholders,
under the Master Trust Deed or the Security Trust Deed. The Issuer, the Class
A-1 Note Trustee, the Manager, the Agent Bank and each Paying Agent may accept
the correctness of the Class A-1 Note Register and any information provided to
it by the Class A-1 Note Registrar and is not required to enquire into its
authenticity. None of the Issuer, the Class A-1 Note Trustee, the Manager, the

defined in the Series Supplement) A$100,000 less the aggregate of all amounts
previously paid in relation to that Note or Redraw Bond on account of principal

      "Prior Interest" means the lien over, and right of indemnification from,
the Charged Property held by the Issuer under, and calculated in accordance
with, the Master Trust Deed for the fees, costs, charges and expenses incurred
by or payable to the Issuer (in its capacity as trustee of the Series Trust) in
accordance with the Master Trust Deed and the Series Supplement (other than the
Secured Moneys) which are unpaid or paid by the Issuer but not reimbursed to
the Issuer from the assets and property of the Series Trust.

      "Secured Creditors" means the Class A-1 Note Trustee (in its personal
capacity and as trustee of the Class A-1 Trust established under the Class A-1
Note Trust Deed), each Agent, each Securityholder, each Hedge Provider (as
defined in the Series Supplement), the Liquidity Facility Provider (as defined
in the Series Supplement), the Standby Redraw Facility Provider (as defined in
the Series Supplement), the Servicer, the Seller and the Manager (only in
respect of the Arranging Fee (as defined in the Series Supplement)).

      "Secured Moneys" means, without double counting, the aggregate of all
moneys owing to the Security Trustee or to a Secured Creditor under any of the
Transaction Documents, whether such amounts are liquidated or not or are
contingent or presently accrued due, and includes all rights sounding in

       of that Security;

  (b)  the amount owing by the Issuer in relation to the principal component
       of the Standby Redraw Facility Agreement is to be calculated by
       reference to the

<PAGE>

      aggregate of the Standby Redraw Facility Principal and the Unreimbursed
      Principal Charge-offs in relation to the Standby Redraw Facility
      Principal;

  (c) the Secured Moneys do not include any fees or value added tax payable
      to the Class A-1 Note Trustee or an Agent referred to in clause 12.7 of
      the Class A-1 Note Trust Deed or Clause 12.6 of the Agency Agreement;
      and

  (d) the Secured Moneys owing to the Manager are limited only to the
      Arranging Fee (as defined in the Series Supplement).

      "Securityholders" means the Class A Noteholders, the Class B Noteholders
(as defined in the Series Supplement) and the Redraw Bondholders (as defined
in the Series Supplement).

  5.3 Limited Recourse

      The liability of the Issuer to make interest and principal payments on
the Class A-1 Securities is limited, except in certain circumstances described
in Condition 12, to the assets and property of the Series Trust available for
this purpose in accordance with, and subject to the order of priority of
payments in, the Series Supplement (prior to enforcement of the Charge) or the
Security Trust Deed (following enforcement of the Charge).

      The net proceeds of realisation of the assets and property of the Series
Trust (including following enforcement of the Charge) may be insufficient to
pay all amounts due to the Class A-1 Noteholders and any other amounts ranking
in priority to or equally with amounts due to the Class A-1 Noteholders.
Except in the limited circumstances described in Condition 12, the assets of
Perpetual held in its personal capacity will not be available for payment of
any shortfall arising and all claims in respect of such shortfall will be
extinguished. The assets of Perpetual held in its capacity as trustee of any
other trust (including any other series trust established pursuant to the
Master Trust Deed) will not in any circumstances be available to pay any
amounts due to Class A-1 Noteholders.

      None of the Bank, the Manager, the Class A-1 Note Trustee, the Security
Trustee, any Agent, each Currency Swap Provider or the Managers (as defined in
the Underwriting Agreement), amongst others, has any obligation to any Class
A-1 Noteholder for payment of any amount owed by the Issuer in respect of the
Class A-1 Notes.

  5.4 No Preference within the Class A-1 Notes

        The Class A-1 Notes rank equally and rateably and without any
  preference or priority among themselves.

  5.5 Ranking of Class A-1 and Class A-2 Notes

      Prior to the enforcement of the Charge, under the Series Supplement the
Class A-1 Notes and Class A-2 Notes will rank equally and rateably in relation
to the payment of interest and the repayment of principal (the amounts payable
by the Issuer under the Series Supplement in relation to the Class A-1 Notes
will be calculated by reference to the applicable Australian dollar amounts
payable by the Issuer to the Currency Swap Providers,

                                      I-6
<PAGE>

which rank equally and rateably with amounts payable in respect of the Class A-
2 Notes, which in turn will be applied to meet the payment of interest and the
repayment of principal (as applicable) on the Class A-1 Notes as explained,
respectively, in Conditions 6.9 and 7.2). Following enforcement of the Charge,
under the Security Trust Deed the payment of amounts owing in relation to the
Class A-1 Notes and the Class A-2 Notes will rank rateably (the amounts owing
in respect of the Class A-1 Notes will, for the purposes of determining
distributions to, and allocations between, the Class A-1 Noteholders, the Class
A-2 Noteholders and the other Secured Creditors, be converted into A$ in
accordance with the Security Trust Deed).

  5.6 Issue of Redraw Bonds

      Under the Series Supplement, the Issuer is entitled to issue debt
securities ("Redraw Bonds") from time to time at the direction of the Manager.
If prior to a Determination Date, the Manager considers that the aggregate of:

  (a)  the Principal Collections, the Principal Charge-Off Reimbursements (as
       defined in Condition 7.10) and the Other Principal Amounts for the
       Collection Period ending on the Determination Date; and

  (b)  the Standby Redraw Facility Advance (as hereinafter defined) (if any)
       to be made on the next Distribution Date (as defined in Condition
       6.2),

      as estimated by the Manager are likely to be insufficient to meet in full
the aggregate of:

  (c)  the Seller Advances; and

  (d)  the Standby Redraw Facility Principal,

      that the Manager estimates will be outstanding on the Determination Date,
the Manager may direct the Issuer to issue Redraw Bonds for a principal amount
specified in the direction. The maximum Stated Amount (as hereinafter defined)
of the Redraw Bonds outstanding on any Distribution Date (after taking into
account any expected repayment of principal on the Redraw Bonds on that
Distribution Date) must not exceed the Redraw Bond Principal Limit.

      "Collection Period", "Determination Date", "Other Principal Amount",
"Principal Collections", "Redraw Bond Principal Limit", "Seller Advance",
"Standby Redraw Facility Advance", "Standby Redraw Facility Principal" and
"Stated Amount" in relation to the Redraw Bonds have the same respective
meanings as in the Series Supplement. For a description of these, see
"Description of the Class A-1 Notes--Key Dates and Periods, --Determination of
the Available Principal Amount and--Redraws" and "Glossary" of this prospectus.

      Prior to the enforcement of the Charge, under the Series Supplement: (i)
the payment of interest on the Redraw Bonds will rank equally and rateably with
the payment of interest on the Class A Notes (or, in the case of the Class A-1
Notes, equally and rateably with the payment of the relevant A$ amount by the
Issuer to the Currency Swap Providers which in

                                      I-7
<PAGE>

turn will be applied to meet the payment of interest on the Class A-1 Notes as
explained in Condition 6.9); and (ii) the repayment of principal on the Redraw
Bonds will rank ahead of the repayment of principal on the Class A Notes (or,
in the case of the Class A-1 Notes, ahead of the payment of the relevant A$
amount by the Issuer to the Currency Swap Providers which in turn will be
applied to meet the repayment of principal on the Class A-1 Notes as explained
in Condition 7.2).

      Following the enforcement of the Charge, under the Security Trust Deed
the payment of amounts owing in relation to the Redraw Bonds will rank rateably
with the payment of amounts owing in relation to the Class A Notes (the amounts
owing in respect of the Class A-1 Notes will, for the purposes of determining
distributions to, and allocations between, the Class A-1 Noteholders and Redraw
Bondholders and other Secured Creditors, be converted into A$ in accordance
with the Security Trust Deed).

  5.7 Subordination of Class B Notes

      Prior to the enforcement of the Charge, the payment of interest in
relation to the Class B Notes is subordinated to, amongst other things, the
payment of interest on the Class A Notes and the Redraw Bonds in accordance
with the Series Supplement; and the repayment of the principal on the Class B
Notes is, to a certain extent, subordinated to, amongst other things, the
repayment of the principal on the Class A Notes and the Redraw Bonds in
accordance with the calculations to be made of the amounts to be paid by the
Issuer under the Series Supplement (in the case of the Class A-1 Notes, the
subordination of the Class B Notes is in respect of the relevant A$ amounts
payable by the Issuer to the Currency Swap Providers which in turn will be
applied to meet the payment of interest and the repayment of principal on the
Class A-1 Notes as explained, respectively, in Conditions 6.9 and 7.2.). For a
description of the order of application of available proceeds under the Series
Trust, the consequent subordination of the payment of interest and repayment of
principal on the Class B Notes, see "Description of the Class A-1 Notes--
Distribution of the Available Income Amount, --Distribution of the Available
Principal Amount and --Allocation of Principal to Class A Notes and Class B
Notes" of this prospectus.

      Following the enforcement of the Charge, in the distribution of the net
proceeds (if any) arising from the enforcement of the Charge, any payment in
relation to the Class B Notes will be subordinated to, amongst other things,
payment of all amounts due in relation to the Class A Notes and the Redraw
Bonds (the amounts owing in respect of the Class A-1 Notes will, for the
purposes of determining distributions to, and allocations between, the Class A-
1 Noteholders, and Class B Noteholders and other Secured Creditors, be
converted into A$ in accordance with the Security Trust Deed). For a
description of the order of application of the proceeds of the enforcement of
the Charge under the Security Trust Deed, see "Description of the Transaction
Documents--The Security Trust Deed--Priorities under the Security Trust Deed"
of this prospectus.

      The Security Trust Deed contains provisions requiring the Security
Trustee, subject to other provisions of the Security Trust Deed, to give
priority to the interests of the Class A Noteholders and the Redraw Bondholders
if there is a conflict between the interests of the

                                      I-8
<PAGE>

Class A Noteholders and the Redraw Bondholders (on the one hand) and any other
Secured Creditor, including the Class B Noteholders (on the other hand). In
determining the interests of the Class A-1 Noteholders, the Security Trustee
may rely on a determination of the Class A-1 Note Trustee.

  5.8 The Securities Rank Equally Except as Provided in the Transaction
  Documents

      The Securities enjoy the same rights, entitlements, benefits and
restrictions except as expressly provided in the Transaction Documents.

6. Interest

  6.1 Period of Accrual

      Each Class A-1 Note accrues interest from (and including) September 18,
2000 (the "Closing Date") and ceases to accrue interest on (but excluding) the
earliest of:

  (a) the date on which the Stated Amount (as hereinafter defined) of the
      Class A-1 Note is reduced to zero and all accrued but previously unpaid
      interest, is paid in full;

  (b) the date on which the Class A-1 Note is redeemed or repaid in full in
      accordance with Condition 7 (other than Condition 7.6) unless, upon
      presentation, payment is improperly withheld or refused in which case
      the Class A-1 Note will continue to bear interest in accordance with
      this Condition 6 (both before and after judgment) until (but excluding)
      whichever is the earlier of:

    (i) the day on which all sums due in respect of the Class A-1 Note up
        to that day are received by or on behalf of the Class A-1
        Noteholder; and

    (ii) the seventh day after notice is given to the Class A-1 Noteholder
         (either in accordance with Condition 11.1 or individually) that,
         where required by Condition 8.2, upon presentation thereof being
         duly made, such payment will be made, provided that upon such
         presentation payment is in fact made; and

  (c) the date on which the Class A-1 Note is deemed to be redeemed in
      accordance with Condition 7.6.

      "Stated Amount" in relation to:

  (a) a Class A-1 Note at any given time means the Initial Invested Amount of
      that Class A-1 Note less the sum of:

    (i) the aggregate of all amounts previously paid in relation to that
        Class A-1 Note on account of principal pursuant to Condition
        7.2(c); and

    (ii) the aggregate of all then Unreimbursed Principal Charge-offs (as
         defined in Condition 7.10) in relation to that Class A-1 Note; and

  (b) any other Security at any given time means (as defined in the Series
      Supplement) A$100,000 less the sum of:

    (i) the aggregate of all amounts previously paid in relation to that A$
        Security on account of principal pursuant to clause 10.3 of the
        Series Supplement; and

                                      I-9
<PAGE>

    (ii) the aggregate of all then Unreimbursed Principal Charge-Offs (as
         defined in the Series Supplement) in relation to that A$ Security.

      For a description of how the Stated Amount is determined for the
Securities see "Description of the Class A-1 Notes--Distribution of the
Available Principal Amounts--Allocations of Principal to Class A Notes and
Class B Notes and--Principal Charge-Off" and "Glossary" of this prospectus.

  6.2 Accrual Periods

      The period that a Class A-1 Note accrues interest in accordance with
Condition 6.1 is divided into periods (each an "Accrual Period"). The first
Accrual Period for a Class A-1 Note commences on (and includes) the Closing
Date and ends on (but does not include) the first Distribution Date thereafter.
Each succeeding Accrual Period for a Class A-1 Note commences on (and includes)
a Distribution Date and ends on (but does not include) the next Distribution
Date. The final Accrual Period for a Class A-1 Note ends on (but does not
include) the date on which interest ceases to accrue on the Class A-1 Note
pursuant to Condition 6.1.

      "Distribution Date" means the 18th day of December, March, June and
September in each year (or, if such a day is not a Business Day, the next
Business Day). The first Distribution Date is December 18, 2000 (or, if that
day is not a Business Day, the next Business Day).

      "Business Day" means any day on which banks are open for business in
Sydney, New York City and London other than a Saturday, a Sunday or a public
holiday in Sydney, New York City or London.

  6.3Interest Rate for the Class A-1 Notes

      The rate of interest ("Interest Rate") payable from time to time in
respect of a Class A-1 Note and an Accrual Period is the aggregate of USD-
LIBOR-BBA (as hereinafter defined) for that Accrual Period and the Issue Margin
(as hereinafter defined) in relation to the Class A-1 Note.

      "USD-LIBOR-BBA" for an Accrual Period will be calculated by the Agent
Bank in accordance with paragraph (a) (or, if applicable, paragraph (b)) below
(subject, in the case of the first Accrual Period, to paragraph (c) below):

  (a) on the second Banking Day before the beginning of the Accrual Period (a
      "Rate Set Date") the Agent Bank will determine the rate "USD-LIBOR-BBA"
      as the applicable Floating Rate Option under the Definitions of the
      International Swaps and Derivatives Association, Inc. ("ISDA") (the
      "ISDA Definitions") being the rate applicable to any Accrual Period for
      three-month deposits in US dollars in the London inter-bank market
      which appears on the Rate Page (as hereinafter defined) as of 11.00am,
      London time, on the Rate Set Date;


                                      I-10
<PAGE>

  (b) if such rate does not appear on the Rate Page at that time, the USD-
      LIBOR-BBA for that Accrual Period will be determined as if the Issuer
      and the Agent Bank had specified "USD-LIBOR-Reference Banks" as the
      applicable Floating Rate Option under the ISDA Definitions. For this
      purpose "USD-LIBOR-Reference Banks" means that the rate for an Accrual
      Period will be determined on the basis of the rates at which deposits
      in US dollars are offered by the Reference Banks (being four major
      banks in the London interbank market determined by the Agent Bank) at
      approximately 11.00am, London time, on the Rate Set Date to prime banks
      in the London interbank market for a period of three months commencing
      on the first day of the Accrual Period and in a Representative Amount
      (as defined in the ISDA Definitions). The Agent Bank will request the
      principal London office of each of the Reference Banks to provide a
      quotation of its rate. If at least two such quotations are provided,
      the USD-LIBOR-BBA for that Accrual Period will be the arithmetic mean
      of the quotations. If fewer than two quotations are provided as
      requested, the USD-LIBOR-BBA for that Accrual Period will be the
      arithmetic mean of the rates quoted by not less than two major banks in
      New York City, selected by the Agent Bank and the Currency Swap
      Providers, at approximately 11.00am, New York City time, on that Rate
      Set Date for loans in US dollars to leading European banks for a period
      of three months commencing on the first day of the Accrual Period and
      in a Representative Amount. If no such rates are available in New York
      City, then the USD-LIBOR-BBA for such Accrual Period will be the most
      recently determined rate in accordance with paragraph (a); and

  (c) the USD-LIBOR-BBA for the first Accrual Period will be the rate
      determined by linear interpolation calculated in accordance with
      paragraph (a) or, if applicable, paragraph (b) above with reference to
      the duration of the first Accrual Period.

      "Banking Day" means any day on which banks are open for business in
London and New York City, other than a Saturday, a Sunday or a public holiday
in London or New York City.

      "Rate Page" means Telerate Page 3750 or, if Telerate Page 3750 ceases to
quote the relevant rate, such other page, section or part of Telerate as
quotes the relevant rate and is selected by the Agent Bank or, if there is no
such page, section or part of such other page, section or part of a different
screen information service as quotes the relevant rate selected by the Agent
Bank and approved by the Class A-1 Note Trustee.

      "Issue Margin" in relation to a Class A-1 Note means, subject to the
following:

  (a) for the period from, and including, the Closing Date to, but excluding,
      the Call Date (as defined in Condition 7.3),   % per annum; and

  (b) for the period from, and including, the Call Date to, but excluding,
      the date on which that Class A-1 Note ceases to accrue interest in
      accordance with Condition 6.1,   % per annum.


                                     I-11
<PAGE>

      If on or after the Call Date the Issuer, at the direction of the Manager,
proposes to exercise its option to redeem the Securities at their Stated Amount
in accordance with Condition 7.3 on a Distribution Date but is unable to do so
because, following a meeting of Securityholders convened under the provisions
of the Security Trust Deed by the Manager for this purpose, the Securityholders
have not approved by an Extraordinary Resolution (as defined in Condition 9.1)
the redemption of the Securities at their Stated Amount, then the Issue Margin
in relation to each Class A-1 Note from, and including, that Distribution Date
to, but excluding, the date on which that Class A-1 Note ceases to accrue
interest in accordance with Condition 6.1, is   % per annum.

      There is no maximum or minimum Interest Rate for the Class A-1 Notes.

  6.4 Calculation of Interest on the Class A-1 Notes

      Interest on each Class A-1 Note for an Accrual Period (the "Class A-1
Interest Amount") is calculated by applying the Interest Rate for that Class A-
1 Note for that Accrual Period to the Invested Amount of that Class A-1 Note on
the first day of the Accrual Period (after taking into account any reductions
in the Invested Amount of that Class A-1 Note on that day), by then multiplying
such product by the actual number of days in the Accrual Period divided by 360
and rounding the resultant figure down to the nearest cent.

      "Invested Amount" in relation to a Class A-1 Note means the Initial
Invested Amount of that Class A-1 Note less the aggregate of all amounts
previously paid in relation to that Class A-1 Note on account of principal
pursuant to Condition 7.2(c).

  6.5 Determination of Interest Rate and Class A-1 Interest Amount

      The Agent Bank will, as soon as practicable after 11.00am (London time
or, if applicable, New York City time) on each Rate Set Date, determine the
Interest Rate in relation to the Class A-1 Notes, and calculate the Class A-1
Interest Amount, for the immediately succeeding Accrual Period in accordance
with, respectively, Conditions 6.3 and 6.4. The determination of the Interest
Rate, and the calculation of the Class A-1 Interest Amount, by the Agent Bank
in accordance with, respectively, Conditions 6.3 and 6.4 will (in the absence
of manifest error, wilful default or bad faith) be final and binding upon all
parties.

  6.6 Notification and Publication of Interest Rate and Class A-1 Interest
  Amount

      The Agent Bank will cause the Interest Rate and the Class A-1 Interest
Amount for each Accrual Period, and the date of the next Distribution Date, to
be notified to the Issuer, the Manager, the Class A-1 Note Trustee, the
Currency Swap Providers, the Paying Agents and the UKLA (for so long as the
Class A-1 Notes are listed on the Official List of the UKLA) on or as soon as
practical after the Agent Bank has determined the Interest Rate and calculated
the Class A-1 Interest Amount or on such earlier date as the UKLA may require
(for so long as the Class A-1 Notes are listed on the Official List of the
UKLA) and will cause the same to be published in accordance with Condition 11.2
as soon as practical after that notification. The Class A-1 Interest Amount and
the Distribution Date may subsequently

                                      I-12
<PAGE>

be amended (or appropriate alternative arrangements made by way of adjustment)
without notice in the event of an extension or shortening of the Accrual
Period. If following the occurrence of an Event of Default (as defined in
Condition 9.1), the Security Trustee declares in accordance with the Security
Trust Deed that the Class A-1 Notes are immediately due and payable, the Class
A-1 Interest Amount and the Interest Rate in respect of the Class A-1 Notes
will nevertheless continue to be calculated by the Agent Bank in accordance
with this Condition, but no publication of the Class A-1 Interest Amount or the
Interest Rate so calculated or the Distribution Dates needs to be made unless,
in the case of the Class A-1 Interest Amount or the Interest Rate, the Class A-
1 Note Trustee otherwise requires.

      For a description of the expression "Event of Default" see "Description
of the Transaction Documents--The Security Trust Deed" and "Glossary" of this
prospectus.

  6.7 Determination or Calculation by the Class A-1 Note Trustee

      If the Agent Bank at any time for any reason does not determine the
Interest Rate in respect of the Class A-1 Notes, or calculate the Class A-1
Interest Amount, in accordance with this Condition 6, the Class A-1 Note
Trustee will do so and each such determination or calculation by the Class A-1
Note Trustee will be as if made by the Agent Bank. In doing so, the Class A-1
Note Trustee will apply the foregoing provisions of this Condition 6, with any
necessary consequential amendments, to the extent that it can and in all other
respects it will do so in such a manner as it considers to be fair and
reasonable in all the circumstances.

  6.8 Agent Bank

      The Issuer will procure that, for so long as any of the Class A-1 Notes
remain outstanding, there will at all times be an Agent Bank. The Issuer, at
the direction of the Manager, may with the prior written approval of the Class
A-1 Note Trustee, terminate the appointment of the Agent Bank immediately on
the occurrence of certain events specified in the Agency Agreement in relation
thereto or, otherwise, by giving not less than 60 days' notice in writing to,
amongst others, the Agent Bank. Notice of that termination will be given by the
Issuer to the Class A-1 Noteholders in accordance with Condition 11.1. If any
person is unable or unwilling to continue to act as the Agent Bank, or if the
appointment of the Agent Bank is terminated, the Issuer, at the direction of
the Manager, will appoint a successor Agent Bank to act as such in its place,
provided that neither the resignation nor removal of the Agent Bank will take
effect until a successor approved by the Class A-1 Note Trustee has been
appointed and notice of the appointment of the successor has been given by the
Issuer to the Class A-1 Noteholders in accordance with Condition 11.1. The
initial Agent Bank and its specified office are set out at the end of these
Conditions.

  6.9 Payment of the Class A-1 Interest Amount

      The Class A-1 Interest Amount for each Accrual Period in relation to a
Class A-1 Note is payable in arrear in US$ on the Distribution Date which is
the last day of the

                                      I-13
<PAGE>

Accrual Period. On each Distribution Date prior to the enforcement of the
Charge, the Issuer must:

  (a) to the extent that there are funds available for this purpose in
      accordance with the Series Supplement pay, in accordance with the
      directions of the Manager, the A$ Class A-1 Interest Amount and any A$
      Class A-1 Unpaid Interest Amount in relation to that Distribution Date
      rateably to the Currency Swap Providers in accordance with the Class A-
      1 Currency Swaps;

  (b) direct each Currency Swap Provider (which direction may be contained in
      the relevant Class A-1 Currency Swap) to pay the Class A-1 Interest
      Payments on each Distribution Date to the Principal Paying Agent in
      accordance with the Agency Agreement; and

  (c) direct the Principal Paying Agent (which direction may be contained in
      the Agency Agreement) to pay the Class A-1 Interest Payments received
      by it from the Currency Swap Providers on a Distribution Date rateably
      amongst the Class A-1 Notes based on their Stated Amounts towards the
      Class A-1 Interest Amount in relation to each Class A-1 Note in
      relation to the Accrual Period ending on that Distribution Date and any
      then Class A-1 Unpaid Interest Amount (as defined in Condition 6.10) in
      relation to each Class A-1 Note (to the extent included in the Class A-
      1 Interest Payment) in accordance with, and subject to, these
      Conditions and the Agency Agreement.

      "A$ Class A-1 Interest Amount", "A$ Class A-1 Unpaid Interest Amount" and
"Class A-1 Interest Payment" have the same respective meanings as in the Series
Supplement. The method for calculating these, the order of application of
available funds for payment of the $A Class A-1 Interest Amount and $A Class A-
1 Unpaid Interest Amount on a Distribution Date and other payments ranking in
priority to or equally with payment of those amounts on a Distribution Date
under the Series Supplement are explained in "Description of the Class A-1
Notes--Distribution of the Available Income Amount and--the Currency Swap--
Interest Payments" of this prospectus.

  6.10 Interest on Unpaid Interest Amounts

      If interest is not paid in respect of a Class A-1 Note on the date when
due and payable, that unpaid interest will itself bear interest at the Interest
Rate in relation to the Class A-1 Notes applicable from time to time until (but
excluding the date of payment) the unpaid interest, and interest on it, is paid
in accordance with Condition 6.9 (the unpaid interest and interest on that
unpaid interest, in relation to a Class A-1 Note, is a "Class A-1 Unpaid
Interest Amount").

7. Redemption of the Class A-1 Notes

  7.1 Final redemption of the Class A-1 Notes

      Unless previously redeemed (or deemed to be redeemed) in full, the Issuer
will redeem the Class A-1 Notes at their then Stated Amount, together with all
then accrued but

                                      I-14
<PAGE>

unpaid interest, on the Distribution Date occurring in December 2031 (the
"Scheduled Maturity Date").

  7.2 Part Redemption of Class A-1 Notes

      Subject to Conditions 7.3, 7.4 and 7.6, on each Distribution Date prior
to the enforcement of the Charge until the Stated Amount of the Class A-1 Notes
is reduced to zero the Issuer must:

  (a) pay, in accordance with the directions of the Manager, the A$ Class A-1
      Principal Amount (if any) in relation to that Distribution Date to the
      Currency Swap Providers in accordance with the Class A-1 Currency
      Swaps;

  (b) direct each Currency Swap Providers (which instruction may be contained
      in the relevant Class A-1 Currency Swap) to pay on each Distribution
      Date to the Principal Paying Agent in accordance with the Agency
      Agreement the US$ Equivalent of the amount of the A$ Class A-1
      Principal Amount (such US$ Equivalent of the A$ Class A-1 Principal
      Amount being the "Class A-1 Principal Amount") received by the Currency
      Swap Provider from the Issuer on that Distribution Date; and

  (c) direct the Principal Paying Agent (which direction may be contained in
      the Agency Agreement) to pay Class A-1 Principal Amount received from
      the Currency Swap Providers equally amongst the Class A-1 Notes towards
      the repayment of the Stated Amount on the Class A-1 Notes in accordance
      with, and subject to, these Conditions and the Agency Agreement. Such a
      payment of the Stated Amount on a Class A-1 Note will constitute a
      redemption of the Class A-1 Note in part to the extent of such
      repayment and, upon such repayment, the obligation of the Issuer with
      respect to the Class A-1 Note will be discharged to the extent of such
      repayment.

      "A$ Class A-1 Principal Amount" and "US$ Equivalent" have the same
respective meanings as in the Series Supplement. The method for calculating
these and the other payments ranking in priority to or equally with the payment
of the A$ Class A-1 Principal Amount on a Distribution Date under the Series
Supplement are described in "Description of Class A-1 Notes--Distribution of
the Available Principal Amount,--Allocation of Principal to Class A Notes and
Class B Notes and--The Currency Swap--Principal Payments of this prospectus.

  7.3 Call Option

      The Issuer will, subject to the other provisions of this Condition 7 and
prior to the enforcement of the Charge, when directed by the Manager (at the
Manager's option), redeem all, but not some only, of the Securities at their
then Invested Amount, subject to the following, together with all accrued but
unpaid interest in respect of the Securities to (but excluding) the date of
redemption, on any Distribution Date falling on or after the earlier of:

  (a) the date on which the aggregate Mortgage Loan Principal (as defined in
      the Series Supplement) expressed as a percentage of the aggregate
      Mortgage Loan Principal at

                                      I-15
<PAGE>

      the beginning of business (Sydney time) on September 1, 2000 falls
      below 10%; and

  (b) the Distribution Date falling in December 2007 (the "Call Date").

      Notwithstanding the foregoing, the Issuer may redeem the Securities at
their Stated Amount, instead of at their Invested Amount, together with
accrued but unpaid interest in respect of the Securities to (but excluding)
the date of redemption, if so approved by an Extraordinary Resolution (as
defined in Condition 9.1) of the Securityholders together.

      The Manager will not direct the Issuer to, and the Issuer will not, so
redeem the Securities on such a Distribution Date unless the Issuer is in a
position on the Distribution Date to repay in respect of the Securities their
then Invested Amount or Stated Amount, as required, 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 Securities
of all classes if the Charge were enforced.

      The Issuer will give not more than 60 nor less than 45 days' notice
(which will be irrevocable) of the Distribution Date on which a proposed
redemption under this Condition 7.3 will occur to the Seller, the Class A-1
Note Trustee, the Principal Paying Agent, the Agent Bank and to the Class A-1
Noteholders in accordance with Condition 11.1.

  7.4 Redemption for Taxation or Other Reasons

      If the Manager satisfies the Issuer and the Class A-1 Note Trustee
immediately prior to giving the notice referred to below that by virtue of a
change in law of the Commonwealth of Australia or any of its political
subdivisions or any of its authorities or any other jurisdiction to which the
Issuer becomes subject (or the application or official interpretation thereof)
(a "Relevant Jurisdiction") from that in effect on the Closing Date, either:

  (a) on the next Distribution Date the Issuer will be required to deduct or
      withhold from any payment of principal or interest in respect of the
      Class A-1 Notes or any other class of the Securities 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 Relevant Jurisdiction; or

  (b) the total amount payable in respect of interest in relation to any of
      the Mortgage Loans (as defined in the Series Supplement) for a
      Collection Period ceases to be receivable (whether or not actually
      received) by the Issuer 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
      Relevant Jurisdiction,

      and, in each case, such obligation cannot be avoided by the Issuer
taking reasonable measures available to it, the Issuer must, when so directed
by the Manager (at the Manager's option), redeem all, but not some only, of
the Securities on any subsequent Distribution Date

                                     I-16
<PAGE>

at their then Invested Amount, subject to the following, together with accrued
but unpaid interest in respect of the Securities to (but excluding) the date of
redemption. Notwithstanding the foregoing, the Issuer may redeem the Securities
at their Stated Amount, instead of at their Invested Amount, together with
accrued but unpaid interest in respect of the Securities to (but excluding) the
date of redemption, if so approved by an Extraordinary Resolution (as defined
in Condition 9.1) of the Securityholders together.

      The Manager will not direct the Issuer to, and the Issuer will not, so
redeem the Securities unless the Issuer is in a position on such Distribution
Date to repay in respect of the Securities their then Invested Amount or Stated
Amount, as required, 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 Securities of all classes if the Charge were
enforced.

      The Issuer will give not more than 60 nor less than 45 days' notice
(which will be irrevocable) of the Distribution Date on which a proposed
redemption under this Condition 7.4 will occur to the Class A-1 Note Trustee,
the Seller, the Principal Paying Agent, the Class A-1 Note Registrar, the Agent
Bank and the Class A-1 Noteholders in accordance with Condition 11.1.

      If an event referred to in paragraph (a) of this Condition 7.4 occurs in
respect of only the Class A-1 Notes (and not any other Securities) and as a
result thereof the Issuer gives notice in accordance with this Condition 7.4
that it proposes to redeem all of the Securities on the Distribution Date
referred to in that notice, the Class A-1 Noteholders may by a Special Majority
(as defined in Condition 10.3) in accordance with the Class A-1 Note Trust Deed
elect that they do not require the Issuer to redeem the Class A-1 Notes. If the
Class A-1 Noteholders make such an election they (or the Class A-1 Note Trustee
on their behalf) must notify the Issuer and the Manager not less than 21 days
before the proposed Distribution Date for the redemption of the Class A-1
Notes. Upon receipt of such a notice, the Issuer must not so redeem the
Securities.

  7.5 Certification

      For the purpose of any redemption made under Condition 7.3 or 7.4, the
Issuer and the Class A-1 Note Trustee may rely on any certificate of an
Authorised Officer (as defined in the Master Trust Deed) of the Manager that
the Issuer will be in a position to repay in respect of the Securities their
then Invested Amount or Stated Amount, as applicable, together with all accrued
but unpaid interest to (but excluding) the date of redemption and to discharge
all its liabilities in respect of amounts required under the Security Trust
Deed to be paid in priority to or equally with the Securities if the Charge
were enforced.

  7.6 Redemption on Final Payment

      Upon a final distribution being made in respect of the Class A-1 Notes
under clause 26.12 of the Series Supplement or clause 13.1 of the Security
Trust Deed, the Class A-1 Notes will thereupon be deemed to be redeemed and
discharged in full and any obligation to

                                      I-17
<PAGE>

pay any accrued but then unpaid Class A-1 Interest Amount or any Class A-1
Unpaid Interest Amount or any then unpaid Invested Amount, Stated Amount or
other amounts in relation to the Class A-1 Notes will be extinguished in full.

      For a description of the circumstances in which a final distribution will
be made in respect of the Class A-1 Notes see "Description of the Class A-1
Notes--Termination of the Trust" and "Description of the Transaction
Documents--The Security Trust Deed" of this prospectus.

  7.7 Cancellation

      All Class A-1 Notes redeemed in full (or deemed to be redeemed in full)
pursuant to the above Conditions will be cancelled and may not be resold or
reissued.

  7.8 No Payment in excess of Stated Amount

      Subject to Conditions 7.3 and 7.4, no amount of principal will be repaid
in respect of a Class A-1 Note in excess of the Stated Amount of the Class A-1
Note.

  7.9 Application of Principal Charge-offs

      If on a Determination Date (as hereinafter defined) any Principal Charge-
off is allocated to the Class A-1 Notes in accordance with the Series
Supplement, it will reduce the Stated Amount of the Class A-1 Notes (equally
and rateably according to their Stated Amount) by an amount equal to the US$
Equivalent of the amount so allocated until the Stated Amount of the Class A-1
Notes is reduced to zero. A reduction in the Stated Amount of a Class A-1 Note
in accordance with the foregoing will take effect on the next Distribution
Date.

      "Determination Date" and "Principal Charge-off" have the same respective
meanings as in the Series Supplement. These expressions, the method of
calculating a Principal Charge-off and the application of a Principal Charge-
off amongst the Securities (and others) are explained in "Description of the
Class A-1 Notes--Key Dates and Periods and--Principal Charge-offs" of this
prospectus.

  7.10 Principal Charge-offs Reimbursement

      If on a Determination Date any Principal Charge-off Reimbursement is
allocated to the Class A-1 Notes in accordance with the Series Supplement, it
will reduce the Unreimbursed Principal Charge-offs of the Class A-1 Notes
(rateably according to their amount of Unreimbursed Principal Charge-offs) by
an amount equal to the US$ Equivalent of the amount so allocated until the
Unreimbursed Principal Charge-offs in respect of the Class A-1 Notes are
reduced to zero. A reduction in the Unreimbursed Principal Charge-offs in
respect of the Class A-1 Notes in accordance with the foregoing, and the
resultant increase in the Stated Amount of the Class A-1 Notes, will take
effect on the next Distribution Date.


                                      I-18
<PAGE>

      "Principal Charge-off Reimbursement" has the same meaning as in the
Series Supplement. This expression, the method of calculating a Principal
Charge-off Reimbursement and the allocation of a Principal Charge-off
Reimbursement amongst the Securities (and others) is explained in "Description
of the Class A-1 Notes--Principal Charge-offs" of this prospectus.

      "Unreimbursed Principal Charge-offs" in relation to a Class A-1 Note at
any time means the aggregate of the US$ Equivalent of the Principal Charge-offs
up to and including that time allocated to the Class A-1 Note in accordance
with Condition 7.9 less the aggregate of the US$ Equivalent of the Principal
Charge-off Reimbursements prior to that time allocated to the Class A-1 Note in
accordance with this Condition 7.10.

  7.11 Calculation of Class A-1 Principal Amounts, Stated Amounts and other
     amounts

  (a) No later than two Business Days prior to each Distribution Date, the
      Manager will determine: (i) the amount of any Class A-1 Principal
      Amount payable in respect of each Class A-1 Note on the Distribution
      Date; (ii) the Stated Amount and Invested Amount of each Class A-1 Note
      as at the first day of the Accrual Period commencing on the
      Distribution Date (after deducting any Class A-1 Principal Amounts due
      to be paid in respect of such Class A-1 Note on that Distribution Date
      and after making any other adjustments to the Stated Amount or the
      Invested Amount (as the case may be) of the Class A-1 Note in
      accordance with these Conditions on or with effect from that
      Distribution Date); (iii) the Class A-1 Note Factor (as defined below)
      as at that Distribution Date; and (iv) the amount of the Class A-1
      Interest Payment to be made on the Distribution Date applicable to each
      Class A-1 Note.

  (b) The Manager will notify the Issuer, the Class A-1 Note Trustee, the
      Principal Paying Agent, the Agent Bank, the Class A-1 Note Registrar
      and the UKLA (for so long as the Class A-1 Notes are listed on the
      Official List of the UKLA) as soon as practical (and in any event by
      not later than two Business Days prior to the Distribution Date or on
      such earlier date as the UKLA may require (for so long as the Class A-1
      Notes are listed on the Official List of the UKLA)) of each
      determination of an amount or percentage referred to in Condition
      7.11(a) and will cause details of each of those determinations to be
      published in accordance with Condition 11.2 as soon as practical after
      that notification. If no Class A-1 Principal Amount is due to be paid
      on the Class A-1 Notes on any Distribution Date the Manager will cause
      a notice to be given in accordance with Condition 11.2 as soon as
      practicable (and in any event by no later than the relevant
      Distribution Date).

  (c) If the Manager does not at any time for any reason make one or more of
      the determinations referred to in Condition 7.11(a) the Agent Bank (or,
      failing the Agent Bank, the Class A-1 Note Trustee) must make such
      determinations in accordance with this Condition (but based on the
      information in its possession) and each such determination will be
      deemed to have been made by the Manager.

                                      I-19
<PAGE>

      "Class A-1 Note Factor" at a given time means the percentage calculated
as follows:
                             CA1NF =   A
                                      ---
                                       B

      where:

    CA1NF = the Class A-1 Note Factor;

    A =      the aggregate Invested Amount of the Class A-1 Notes on the
             last day of the just ended Accrual Period; and

    B =      the aggregate Initial Invested Amount of the Class A-1 Notes.

8. Payments

  8.1 Method of Payment

      Any instalment on account of interest or principal payable on any Class
A-1 Note which is punctually paid or duly provided for by or on behalf of or at
the direction of the Issuer to the Principal Paying Agent on the applicable
Distribution Date shall be paid to the person in whose name such Class A-1 Note
is registered on the relevant Record Date (as defined below), by wire transfer
in immediately available funds to the account designated by such person or, if
such person so requests in writing, by cheque mailed first-class, postage
prepaid, to such person's address as it appears on the Class A-1 Note Register
on such Record Date.

      "Record Date" in relation to a Distribution Date or any other date for
any payment to be made in respect of a Class A-1 Note means the day which is
the last day of the prior calendar month.

  8.2 Surrender on Final Payment

      Prior to a final distribution being made in respect of the Class A-1
Notes under clause 26.12 of the Series Supplement or clause 13.1 of the
Security Trust Deed the Class A-1 Note Trustee must notify the persons in whose
names the Class A-1 Notes are registered on the relevant Record Date of the
date upon which the Class A-1 Note Trustee expects that final distribution to
be made and specify if that such final distribution will be payable only upon
surrender of the relevant Class A-1 Note to a Paying Agent at its specified
office. No such final distribution will be made other than upon the surrender
of the relevant Class A-1 Notes and none of the Issuer, the Class A-1 Note
Trustee, the Security Trustee or any Paying Agent will be liable to pay any
additional amount to any Class A-1 Noteholder as a result of any delay in
payment due to a Class A-1 Note not having been surrendered in accordance with
this Condition 8.2.

      For a description of the circumstances in which a final distribution will
be made in respect of the Class A-1 Notes see "Description of the Class A-1
Notes--Termination of the Trust" and "Description of the Transaction
Documents--The Security Trust Deed" of this prospectus.

<PAGE>

  8.3 Paying Agents

      The initial Paying Agents and their respective specified offices are set
out at the end of these Conditions.

      The Issuer, at the direction of the Manager, may with the prior written
approval of the Class A-1 Note Trustee terminate the appointment of the
Principal Paying Agent and appoint additional or other Paying Agents, provided
that it will at all times maintain a Paying Agent having a specified office in
London and New York City. Notice of any such termination or appointment and of
any change in the office through which any Paying Agent will act will be given
in accordance with Condition 11.1.

  8.4 Taxation

      All payments in respect of the Class A-1 Notes will be made without
withholding or deduction for, or on account of, any present or future taxes,
duties or charges of whatsoever nature unless the Issuer or any Paying Agent is
required by any applicable law to make such a withholding or deduction. In that
event the Issuer or that Paying Agent (as the case may be) will, after making
such withholding or deduction, account to the relevant authorities for the
amount so required to be withheld or deducted. Neither the Issuer nor any
Paying Agent nor the Class A-1 Note Trustee will be obliged to make any
additional payments in respect of the relevant Class A-1 Notes in relation to
that withholding or deduction. Immediately after becoming aware that such a
withholding or deduction is or will be required, the Issuer will notify the
Class A-1 Note Trustee, the Principal Paying Agent and the Class A-1
Noteholders in accordance with Condition 11.1, thereof.

  8.5 Prescription

      A Class A-1 Note will become void in its entirety unless surrendered for
payment within a period of 10 years from the Relevant Date in respect of any
payment of principal or interest thereon the effect of which would be to reduce
the Stated Amount of, and all accrued but unpaid interest on, that Class A-1
Note to zero. After the date on which a Class A-1 Note becomes void in its
entirety, no claim can be made in respect of it.

      "Relevant Date" in respect of a Class A-1 Note means the date on which a
payment in respect thereof first becomes due or (if the full amount of the
moneys payable in respect of the Class A-1 Notes due on or before that date has
not been duly received by the Principal Paying Agent or the Class A-1 Note
Trustee on or prior to such date) the date on which, the full amount of such
moneys having been so received and notice to that effect is duly given to the
Class A-1 Noteholders in accordance with Condition 11.1.

  8.6 Notify Late Payments

      In the event of the unconditional payment to the Principal Paying Agent
or the Class A-1 Note Trustee of any sum due in respect of the Class A-1 Notes
or any of them being made after the due date for payment thereof, the Issuer
will forthwith give or procure to be given notice to the Class A-1 Noteholders
in accordance with Condition 11.1 that such payment has been made.

                                      I-21
<PAGE>

  8.7 Rounding of Payments

      All payments in respect of the Class A-1 Notes will be rounded down to
the nearest cent.

9. Enforcement following occurrence of Event of Default

  9.1 Enforcement

      The Security Trust Deed provides that at any time after the Security
Trustee becomes actually aware of the occurrence of an Event of Default, the
Security Trustee will (subject to Condition 10.4 and subject to being
appropriately indemnified), if so directed by an Extraordinary Resolution of
the Voting Secured Creditors, declare the Securities immediately due and
payable (in which case, subject to Condition 12, the Stated Amount of, and all
accrued but unpaid interest in relation to, the Class A-1 Notes will become
immediately due and payable) and enforce the Charge.

      Subject to being indemnified in accordance with the Security Trust Deed
and to the provisions of Condition 9.2, the Security Trustee will take all
action necessary to give effect to any direction in accordance with the
foregoing and will comply with all such directions.

      "Event of Default", "Extraordinary Resolution" and "Voting Secured
Creditors" have the same respective meanings as in the Security Trust Deed. For
a description of these expressions, see "Description of the Transaction
Documents--The Security Trust Deed" and "Glossary" of this prospectus.

  9.2 Security Trustee May Enforce Charge Without Direction

      After the Security Trustee becomes actually aware of the occurrence of an
Event of Default, provided that it has been indemnified to its satisfaction in
accordance with the Security Trust Deed, the Security Trustee must enforce the
Security Trust Deed without an Extraordinary Resolution of the Voting Secured
Creditors if in its opinion, the delay required to obtain the consent of the
Voting Secured Creditors would be prejudicial to the interests of the Secured
Creditors as a class.

  9.3 Priority of Payments from Proceeds from the enforcement of the Charge

      Following the enforcement of the Charge, all moneys received in
connection with the Security Trust Deed by the Security Trustee or by any
receiver appointed in relation to the Charged Property pursuant to the
provisions of the Security Trust Deed are to be applied, subject to the
Security Trust Deed, in accordance with the order of priority contained in the
Security Trust Deed. For a description of the order of priority contained in
the Security Trust Deed and the payment of amounts that rank in priority to or
equally with the Class A-1 Notes, see "Description of the Transaction
Documents--The Security Trust Deed--Priorities under the Security Trust Deed"
of this prospectus.

<PAGE>

  9.4  Security Trustee and Class A-1 Note Trustee Not Liable for Loss on
    enforcement

      Except in the case of fraud, negligence or wilful default (in the case of
the Security Trustee) and, subject to the mandatory provisions of the Trust
Indenture Act, fraud, negligence (except as specifically provided in the Trust
Indenture Act), wilful default or breach of trust (in the case of the Class A-1
Note Trustee), neither the Class A-1 Note Trustee nor the Security Trustee is
liable for any decline in the value, nor any loss realised upon any sale or
other disposition made under the Security Trust Deed of any Charged Property or
any other property which is charged to the Security Trustee by any other person
in respect of or relating to the obligations of the Issuer or any third party
in respect of the Issuer or the Class A-1 Notes or relating in any way to the
Charged Property. Without limitation, neither the Class A-1 Note Trustee nor
the Security Trustee will be liable for any such decline or loss directly or
indirectly arising from its acting, or failing to act, as a consequence of an
opinion reached by it based on advice received by it in accordance with the
applicable requirements of the Class A-1 Note Trust Deed (and the Trust
Indenture Act) or the Security Trust Deed, as the case may be.

      "Trust Indenture Act" means the Trust Indenture Act 1939 of the United
States of America as in force at the date of the Class A-1 Note Trust Deed.

  9.5 Directions from Class A-1 Noteholders to Class A-1 Note Trustee
      following Event of Default

      If an Event of Default or Potential Event of Default has occurred and is
known to the Class A-1 Note Trustee, the Class A-1 Note Trustee must: (a)
notify each Class A-1 Noteholder of the Event of Default or Potential Event of
Default, as the case may be, within 10 days (or such shorter period as may be
required by the rules of the UKLA, if the Class A-1 Notes are listed on the
Official List of the UKLA, or the rules of any other stock exchange on which
the Class A-1 Notes are listed) after becoming aware of the Event of Default or
Potential Event of Default, provided that except in the case of a default in
payment of principal or interest on any Class A-1 Note, the Class A-1 Note
Trustee may withhold such notice if and so long as the board of directors, the
executive committee or a trust committee of its directors and/or its authorised
officers under the Class A-1 Note Trust Deed in good faith determine that
withholding the notice is in the interest of Class A-1 Noteholders; (b) if a
meeting of Voting Secured Creditors is to be held under the Security Trust
Deed, determine whether it proposes to seek directions from Class A-1
Noteholders as to how to vote at that meeting and, if so, whether it proposes
to instruct the Security Trustee to delay the holding of that meeting while it
obtains such directions from the Class A-1 Noteholders; and (c) vote at any
meeting of Voting Secured Creditors held under the Security Trust Deed in
accordance, where applicable, with the directions of the Class A-1 Noteholders
(whether or not solicited and whether or not all Class A-1 Noteholders have
provided such directions) 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 of Voting Secured Creditors under the Security Trust Deed in the same
proportion as that of the aggregate Invested Amounts of

                                      I-23
<PAGE>

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 such a proposal.

      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 at a meeting of Voting
Secured Creditors under the Security Trust Deed, or otherwise direct the
Security Trustee, to dispose of the Charged Property unless: (a) a sufficient
amount would be realised to discharge in full all amounts owing to the Class A-
1 Noteholders in respect of the Class A-1 Notes and any other amounts owing by
the Issuer to any other person ranking in priority to or with the Class A-1
Notes; (b) the Class A-1 Note Trustee is of the opinion, reached after
considering at any time and from time to time the advice of an investment bank
or other financial adviser selected by the Class A-1 Note Trustee, that the
cash flow receivable by the Issuer (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, to discharge in full in due course all
the amounts referred to in paragraph (a); or (c) the Class A-1 Note Trustee is
so directed by a Special Majority (as defined in Condition 10.3) of Class A-1
Noteholders.

      Subject to the mandatory provisions of the Trust Indenture Act and
provisions in the Class A-1 Note Trust Deed relating to the deemed receipt of
notices, the Class A-1 Note Trustee will only be considered to have knowledge
or awareness of, or notice of, an Event of Default or Potential Event of
Default by virtue of the officers of the Class A-1 Note Trustee (or any related
body corporate of the Class A-1 Note Trustee) which have the day to day
responsibility for the administration or management of the Class A-1 Note
Trustee's (or a related body corporate of the Class A-1 Note Trustee's)
obligations in relation to the Series Trust, the trust created under the Class
A-1 Note Trust Deed or the Class A-1 Note Trust Deed, having actual knowledge,
actual awareness or actual notice of the occurrence of the events or
circumstances constituting an Event of Default or Potential Event of Default,
as the case may be, or grounds or reason to believe that such events or
circumstances have occurred.

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

  9.6 Only Security Trustee May Enforce Charge

      Only the Security Trustee may enforce the Charge and neither the Class A-
1 Note Trustee nor any Class A-1 Noteholder (nor any other Secured Creditor) is
entitled to proceed directly against the Issuer to enforce the performance of
any of the provisions of the Security Trust Deed, the Class A-1 Note Trust
Deed, the Class A-1 Notes or any other applicable Transaction Document, except
as provided for in the Security Trust Deed, the Class A-1 Note Trust Deed, the
Master Trust Deed and the Series Supplement. The Security Trustee is not
required to act in relation to the enforcement of the Charge unless its
liability is limited in a manner reasonably satisfactory to it or, if required
by the Security Trustee (in its absolute discretion), it is adequately
indemnified from the Charged Property or the Security

                                      I-24
<PAGE>

Trustee receives from the Voting Secured Creditors an indemnity in a form
reasonably satisfactory to the Security Trustee (which may be by way of an
Extraordinary Resolution of the Voting Secured Creditors) and is put in funds
to the extent necessary.

  9.7 Exercise of Class A-1 Noteholder Rights by Class A-1 Note Trustee

      The rights, remedies and discretions of the Class A-1 Noteholders under
the Security Trust Deed including all rights to vote or to give an instruction
or consent can only be exercised by the Class A-1 Note Trustee on behalf of the
Class A-1 Noteholders in accordance with 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 from time to
time and need not inquire whether any such instructions or directions are in
accordance with the Class A-1 Note Trust Deed, whether the Class A-1 Note
Trustee or the Class A-1 Noteholders from time to time have complied with any
requirements under the Class A-1 Note Trust Deed or as to the reasonableness or
otherwise of the Class A-1 Note Trustee.

10. Meetings of Voting Secured Creditors, directions of Class A-1 Noteholders,
  modifications, consents, waivers and indemnities

  10.1 Meetings of Voting Secured Creditors

      The Security Trust Deed contains provisions for convening meetings of the
Voting Secured Creditors to, among other things, enable the Voting Secured
Creditors to direct or consent to the Security Trustee taking or not taking
certain actions under the Security Trust Deed; for example to enable the Voting
Secured Creditors, following the occurrence of an Event of Default, to direct
the Security Trustee to declare the Securities immediately due and payable
and/or to enforce the Charge.

  10.2 Directions of 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. 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 an Invested
Amount of greater than 50% of the aggregate Invested 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 Invested 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.

<PAGE>

      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 Invested 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 5.30 pm on that date.

  10.3 Amendments to Class A-1 Note Trust Deed and the Class A-1 Notes

      Pursuant, and subject, to the Class A-1 Note Trust Deed and subject to
any approval required by law, the Class A-1 Note Trustee, the Manager and the
Issuer may together agree, without the consent or sanction of any Class A-1
Noteholder, by way of supplemental deed to alter, add to or revoke (each a
"modification") any provision of the Class A-1 Note Trust Deed or the Class A-1
Notes (including these Conditions) so long as such modification is not a
Payment Modification (as defined below) and such modification in the opinion of
the Class A-1 Note Trustee:

  (a) is necessary or expedient to comply with the provisions of any statute
      or regulation or with the requirements of any governmental agency;

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

  (c) is appropriate or expedient as a consequence of an amendment to any
      statute or regulation or altered requirements of any governmental
      agency or any decision of any court (including, without limitation, a
      modification which is in the opinion of the Class A-1 Note Trustee
      appropriate or expedient as a consequence of the enactment of a statute
      or regulation or an amendment to any statute or regulation or ruling by
      the Australian Commissioner or Deputy Commissioner of Taxation or any
      governmental announcement or statement or any decision of any court, 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 the
      Series Trust or the trust constituted under the Class A-1 Note Trust
      Deed); or

  (d) and the Issuer is otherwise desirable for any reason and:

    (i) 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 Class A-1 Noteholders; or

    (ii) 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 Class A-1 Noteholders the consent of a Special Majority (as
         hereinafter defined) of Class A-1 Noteholders is obtained.

      For the purpose of determining whether a Special Majority of Class A-1
Noteholders has consented to a modification, Class A-1 Notes which are
beneficially owned by the Issuer or the Manager or by any person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Issuer or the Manager, will be disregarded. The Manager must
give the Rating Agencies 5 Business Days' prior notice of any such

                                      I-26
<PAGE>

modification. The Class A-1 Note Trustee will be entitled to assume that any
proposed modification, other than a Payment Modification, will not be
materially prejudicial to the interest of Class A-1 Noteholders if each of the
Rating Agencies confirms in writing that if the modification is effected this
will not lead to a reduction, qualification or withdrawal of the then rating
given to the Class A-1 Notes by that Rating Agency.

      Pursuant to the Class A-1 Note Trust Deed, the Class A-1 Note Trustee may
concur with the Issuer and the Manager in making or effecting any Payment
Modification if and only if the consent has first been obtained of each Class
A-1 Noteholder to such Payment Modification.

      Any supplemental deed that effects any such modifications must conform to
the requirements of the Trust Indenture Act and copies of any such supplemental
deed must be distributed by the Issuer to the Class A-1 Noteholders in
accordance with Condition 11.1 as soon as reasonably practicable after the
modifications have been made.

      "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
(including the Conditions) which modifies: (a) the amount, timing, place,
currency or manner of payment of principal or interest in respect of the Class
A-1 Notes including, without limitation, any modification to the Stated Amount,
Invested Amount, Interest Rate or Scheduled Maturity Date in respect of the
Class A-1 Notes or to Conditions 6.9 and 7.2, clause 10 of the Series
Supplement or clause 13 of the Security Trust Deed or which would impair the
rights of Class A-1 Noteholders to institute suit for enforcement of such
payment on or after the due date for such payment; (b) the definition of the
term "Special Majority", clause 21.4 of the Class A-1 Note Trust Deed or the
circumstances in which the consent or direction of a Special Majority of Class
A-1 Noteholders is required; (c) clause 6.1(a) of the Security Trust Deed; or
(d) the requirements for altering, adding to or revoking any provision of the
Class A-1 Note Trust Deed or the Class A-1 Notes (including the Conditions).

      "Rating Agency" has the same meaning as in the Series Supplement.

      "Special Majority" in relation to the Class A-1 Noteholders means Class
A-1 Noteholders holding Class A-1 Notes with an aggregate Invested Amount of no
less than 75% of the aggregate Invested Amount of all the Class A-1 Notes.

      For a further description of the modifications which constitute a Payment
Modification see "Description of the Class A-1 Notes--Amendments to Class A-1
Notes and Class A-1 Note Trust Deed" of this prospectus.

  10.4 Waivers, etc.

      The Security Trustee may, in accordance with the Security Trust Deed and
without the consent or sanction of the Voting Secured Creditors (but not in
contravention of an Extraordinary Resolution of the Voting Secured Creditors),
waive or authorise any breach or proposed breach or determine that any event
that would otherwise be an Event of Default will not be treated as such if and
in so far as in its opinion the interests of the Secured

                                      I-27
<PAGE>

Creditors will not be materially prejudiced. Any such waiver, authorisation or
determination shall be binding on the Secured Creditors and, if, but only if,
the Security Trustee so requires, any such waiver, authorisation or
determination will be notified to the Secured Creditors by the Manager in
accordance with the Security Trust Deed.

      The Class A-1 Note Trustee may, and if directed to do so by a Majority of
Class A1 Noteholders must, on such terms and conditions as it may deem
reasonable, without the consent of any of the Class A-1 Noteholders, and
without prejudice to its rights in respect of any subsequent breach, agree to
any waiver or authorisation of any breach or proposed breach of any of the
terms and conditions of the Transaction Documents by the Issuer, the Manager or
any other person which, unless the Class A-1 Note Trustee is acting on the
direction of a Majority of Class A-1 Noteholders, is not, in the opinion of the
Class A-1 Note Trustee, materially prejudicial to the interests of the Class A-
1 Noteholders as a class. No such waiver, authorisation or determination may be
made in contravention of any prior directions by a Majority (as hereinafter
defined) of the Class A-1 Noteholders. Any such waiver, authorisation or
determination will, if the Class A-1 Note Trustee so requires, be notified to
the Class A-1 Noteholders in accordance with Condition 11.1 by the Issuer as
soon as practicable after it is made.

      "Majority" in relation to the Class A-1 Noteholders means Class A-1
Noteholders holding Class A-1 Notes with an aggregate Invested Amount of
greater than 50% of the aggregate Invested Amount of all the Class A-1 Notes.

  10.5 Indemnification and Exoneration of the Class A-1 Note Trustee and the
      Security Trustee

      The Class A-1 Note Trust Deed and the Security Trust Deed contain
provisions for the indemnification of the Class A-1 Note Trustee and the
Security Trustee (respectively) and for their relief from responsibility,
including provisions relieving them from taking proceedings to realise the
security and to obtain repayment of the Securities unless indemnified to their
satisfaction. Each of the Class A-1 Note Trustee and the Security Trustee is
entitled, subject in the case of the Class A-1 Note Trustee to the mandatory
provisions of the Trust Indenture Act, to enter into business transactions with
the Issuer and/or any other party to the Transaction Documents without
accounting for any profit resulting from such transactions.

      Subject to the mandatory provisions of the Trust Indenture Act, the Class
A-1 Note Trustee shall not be responsible for any loss, expense or liability
occasioned to the Charged Property or any other property or in respect of all
or any of the moneys which may stand to the credit of the Collections Account
(as defined in the Series Supplement) from time to time however caused
(including, without limitation, where caused by an act or omission of the
Security Trustee) unless that loss is occasioned by the fraud, negligence,
wilful default or breach of trust of the Class A-1 Note Trustee. The Security
Trustee is not, nor is any receiver appointed in relation to the Charged
Property pursuant to the provisions of the Security Trust Deed, liable or
otherwise accountable for any omission, delay or mistake or any loss or
irregularity in or about the exercise, attempted exercise, non-exercise or

                                      I-28
<PAGE>

purported exercise of any of the powers of the Security Trustee or of the
receiver under the Security Trust Deed except for fraud, negligence or wilful
default.

      Except in the case of fraud, negligence (except as specifically provided
in the Trust Indenture Act), wilful default or breach of trust, and subject to
the mandatory provisions of the Trust Indenture Act, the Class A-1 Note Trustee
may act on the opinion or advice of, or information obtained from, any lawyer,
valuer, banker, broker, accountant or other expert appointed by the Class A-1
Note Trustee, or by a person other than Class A-1 Note Trustee, where that
opinion, advice or information is addressed to the Class A-1 Note Trustee or by
its terms is expressed to be capable of being relied upon by the Class A-1 Note
Trustee. Except as provided above, the Class A-1 Note Trustee will not be
responsible to any Class A-1 Noteholder, amongst others, for any loss
occasioned by so acting in reliance on such advice. Any such opinion, advice or
information may be sent or obtained by letter, telex or facsimile transmission
and the Class A-1 Note Trustee will not be liable to any Class A-1 Noteholder,
amongst others, for acting on any opinion, advice or information conforming
with any applicable requirements of the Class A-1 Note Trust Deed or the Trust
Indenture Act and purporting to be conveyed by such means even though it
contains some error which is not a manifest error or is not authentic.

11. Notices

  11.1 General

      All notices, other than notices given in accordance with the following
paragraph and Condition 11.2, to Class A-1 Noteholders will be deemed given if
in writing and mailed, first-class, postage prepaid to each Class A-1
Noteholder, at his or her address as it appears on the Class A-1 Note Register,
not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. In any case where notice to Class A-1
Noteholders is given by mail, neither the failure to mail such notice nor any
defect in any notice so mailed to any particular Class A-1 Noteholder will
affect the sufficiency of such notice with respect to other Class A-1
Noteholders, and any notice that is mailed in the manner herein provided will
conclusively be presumed to have been duly given.

      A notice may be waived in writing by the relevant Class A-1 Noteholder,
either before or after the event, and such waiver will be the equivalent of
such notice. Waivers of notice by Class A-1 Noteholders will be filed with the
Class A-1 Note Trustee but such filing will not be a condition precedent to the
validity of any action taken in reliance upon such a waiver.

      Any such notice will be deemed to have been given on the date such notice
is deposited in the mail.

      In case, by reason of the suspension of regular mail services as a result
of a strike, work stoppage or similar activity, it is impractical to mail
notice of any event to Class A-1 Noteholders when such notice is required to be
given, then any manner of giving such notice as the Issuer directs the Class A-
1 Note Trustee will be deemed to be a sufficient giving of such notice.

                                      I-29
<PAGE>

  11.2 Class A-1 Note Information

      Any notice specifying a Distribution Date, an Interest Rate in relation
to the Class A-1 Notes, a Class A-1 Interest Amount, a Class A-1 Principal
Amount (or the absence of a Class A-1 Principal Amount), an Invested Amount, a
Stated Amount, a Class A-1 Note Factor in relation to the Class A-1 Notes, or
any other matter permitted to be given in accordance with this Condition 11.2,
will be deemed to have been duly given if the information contained in the
notice appears on the relevant page of the Reuters Screen or the electronic
information system made available to its subscribers by Bloomberg, L.P. or
another similar electronic reporting service approved by the Class A-1 Note
Trustee in writing and notified to Class A-1 Noteholders pursuant to Condition
11.1 (the "Relevant Screen"). Any such notice will be deemed to have been given
on the first date on which such information appeared on the Relevant Screen. If
it is impossible or impracticable to give notice in accordance with this
paragraph then notice of the matters referred to in this Condition will be
given in accordance with Condition 11.1.

  11.3 Quarterly Servicing and Other Reports

      The Manager must deliver a Quarterly Servicing Report for each Accrual
Period to the Class A-1 Note Trustee, the Principal Paying Agent, the Issuer
and each Class A-1 Noteholder on the Business Day preceding the Distribution

UKLA file each Quarterly Servicing Report with the UKLA as and when required by
the rules of the UKLA.

by the Issuer or the Manager in accordance with the Securities and Exchange Act
1934 of the United States of America or the rules and regulations of the
Securities and Exchange Commission.

        determined by the Manager, with respect to the Mortgage Loans
        forming part of the Assets of the Series Trust as at opening of

      "Note Factor" in relation to a class of Securities and a Distribution
Date, means the aggregate of the Invested Amount of the class of Securities
less all principal payments on that class of Securities to be made on that
Distribution Date, divided by the aggregate initial Invested Amount of that
class of Securities.

      Further details of the cashflows of the Series Trust and the manner of
determination of the defined terms relevant to those cashflows and set out in
the Quarterly Servicing Report are contained in "Description of the Class A-1
Notes" of this prospectus.

  11.4 Consents in Writing

      All consents and approvals in these Conditions must be given in writing.

12.Limitation of liability of the Issuer

  (a) The Issuer enters into the Transaction Documents, and issues the Class
      A-1 Notes, only in its capacity as trustee of the Series Trust and in
      no other capacity (except where the Transaction Documents provide
      otherwise). A liability arising under or in connection with the Class
      A-1 Notes, the Transaction Documents or the Series Trust is limited to
      and can be enforced against the Issuer only to the extent to which it
      can be satisfied out of the assets and property of the Series Trust out
      of which the Issuer is actually indemnified for the liability. This
      limitation of the Issuer's liability applies despite any other
      provision of the Transaction Documents (other than paragraph (c) below)
      and extends to all liabilities and obligations of the Issuer in any way
      connected with any representation, warranty, conduct, omission,
      agreement or transaction related to the Transaction Documents, the
      Class A-1 Notes or the Series Trust.

  (b) No person may sue the Issuer in respect of liabilities incurred by the
      Issuer in its capacity as trustee of the Series Trust other than as
      trustee of the Series Trust or seek the appointment of a receiver
      (except under the Security Trust Deed), a liquidator, an administrator
      or any similar person to the Issuer or prove in any liquidation,
      administration or similar arrangements of or affecting the Issuer
      (except in relation to the assets or property of the Series Trust).

  (c) The provisions of this Condition 12 will not apply to any obligation or
      liability of the Issuer 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's indemnification or exoneration
      out of the assets or property of the Series Trust as a result of the
      Issuer's fraud, negligence or wilful default.

  (d) The Relevant Parties are responsible under the Transaction Documents
      for performing a variety of obligations relating to the Series Trust.
      No act or omission of the Issuer (including any related failure to
      satisfy its obligations under the

                                      I-32
<PAGE>

      Transaction Documents or the Class A-1 Notes) will be considered fraud,
      negligence or wilful default of the Issuer for the purpose of paragraph
      (c) to the extent to which the act or omission was caused or
      contributed to by any failure by any Relevant Party or any other person
      appointed by the Issuer under any Transaction Document (other than a
      person whose acts or omissions the Issuer is liable for in accordance
      with any Transaction Document) to fulfil its obligations relating to
      the Series Trust or by any other act or omission of a Relevant Party or
      any other such person.

  (e) In exercising their powers under the Transaction Documents, each of the
      Security Trustee, the Class A-1 Note Trustee and the Class A-1
      Noteholders must ensure that no attorney, agent, delegate, receiver or
      receiver and manager appointed by it in accordance with a Transaction
      Document has authority to act on behalf of the Issuer in a way which
      exposes the Issuer to any personal liability and no act or omission of
      any such person will be considered fraud, negligence or wilful default
      of the Issuer for the purpose of paragraph (c).

  (f) The Issuer is not obliged to enter into any commitment or obligation
      under these Conditions or any other Transaction Document (including
      incur any further liability) unless the Issuer's liability is limited
      in a manner which is consistent with this Condition 12 or otherwise.

      in a manner satisfactory to the Issuer in its absolute discretion.
"Relevant Parties" means each of the Manager, the Seller, the Servicer, the
Agent Bank, each Paying Agent, the Class A-1 Note Trustee and the Hedge
Providers (as those parties, which are not defined in these Conditions, are
defined in the Series Supplement).

      The expression "fraud, negligence or wilful default" is to be construed
in accordance with the Security Trust Deed.

      A summary of the definition of "wilful default" and further details of
the manner in which the Issuer's liability is limited in relation to the Class
A-1 Notes and the Series Trust are contained in "Description of the Transaction
Documents--The Issuer Trustee" of this prospectus.

13. Governing Law

      The Class A-1 Notes and the Transaction Documents are governed by, and
will be construed in accordance with, the laws of the State of New South Wales
of the Commonwealth of Australia, except for the Underwriting Agreement and
each credit support annex to the Currency Swap Agreements which are governed
by, and will be construed in accordance with, New York law. Each of the Issuer
and the Manager has in the Class A-1 Note Trust Deed irrevocably agreed for the
benefit of the Class A-1 Note Trustee and the Class A-1 Noteholders that the
courts of the State of New South Wales are to have non-exclusive jurisdiction
to settle any disputes which may arise out of or in connection with the Class
A-1 Note Trust Deed and the Class A-1 Notes.

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.
