                                      absolute discretion agree to extend the
                                      term, in which case the term will end on

Security:                              All existing security securing Collins's
                                       obligations to Westpac.

2.   The Facility

Facility

Collins can draw accommodation under the facilities on any Business Day using
any of the options specified above (each an Option). Each drawing must not
exceed the undrawn portion of the Option limit allocated to the relevant Option.

Conditions Precedent

Before Collins can draw accommodation, Collins must sign and return a copy of
this agreement; and Westpac must have received:

(a)  for drawings under the Bill Option, a drawdown notice in the form of
     Schedule 2 by 10am (local time) at least 2 Business Days before the
     proposed date for accepting and discounting Bills (the Drawdown Date);

(b)  a verification certificate in the form of Schedule 1 with the attachments
     referred to in that certificate;

(c)  any fees payable before or on the Drawdown Date as set out in clause 1
     "Facility Details"; and

(d)  where a security document has previously been given to Westpac by another
     entity for another transaction, and is to be used to secure the facility,
     consent from that entity.

No default

Westpac is not obliged to provide any accommodation under this agreement if on
the Drawdown Date there is, or has occurred:

..    a continuing Event of Default (as defined in the Guarantee), or

..    a breach or other event which with notice or time or both would become an
     Event of Default.

Cancellation of Commitment

Collins may cancel all or part of the undrawn Commitment by giving 3 Business
Days irrevocable notice to Westpac. This notice will advise which of the Option
limits the reduction relates to. Cancellations must be in multiples of $100,000.

Change of Allocation

Collins may from time to time by 3 Business Days notice to Westpac reallocate
the undrawn portion of the Option Limits between the Options provided the
aggregate of the resulting limits for

                         (C)Westpac Banking Corporation                   Page 3

<PAGE>

                                          Collins Restaurants Management Pty Ltd

the Options does not exceed the Commitment. A limit applying to an Option cannot
be reduced below the aggregate of all amounts outstanding under that Option.

Such notice will be in the form of Schedule 3.

3.   Overdraft Option

Interest Calculation

Interest on amounts drawn under the Overdraft Option is calculated daily and
charged to the Collins' account monthly in arrears on the last business day of
each month (or such other times as Westpac determines).

Overdraft Account

Collins must nominate or establish one or more current accounts with Westpac to
which the Overdraft Option limit will be allocated. If a new account is to be
established, Collins must satisfy Westpac's usual requirements for opening
accounts of that nature.

Use of facility

Collins may use the Overdraft Option by either:

(a)  drawing a cheque on the overdraft account; or

(b)  making a withdrawal from the overdraft account in any other manner
     permitted by Westpac.

4.   Facility Procedures - Bill Option

Preparation of Bills

Westpac need not prepare Bills, and ordinarily will not do so. Only Westpac may
require that physical Bills be brought into existence. However, Westpac may
itself prepare Bills or require Collins to prepare Bills under this agreement.

If Westpac does not require the physical preparation of Bills it will be taken
to have prepared, signed on behalf of Collins (as drawer) accepted and
discounted Bills in compliance with this agreement. This agreement will apply as
if:

(a)  Westpac had prepared, accepted and discounted those Bills, and

(b)  Collins had signed those Bills as drawer.

Form of Bills

Bills prepared under this agreement must:

                         (C)Westpac Banking Corporation                   Page 4

<PAGE>

                                          Collins Restaurants Management Pty Ltd

(a)  be in a form acceptable to Westpac, and to the extent practicable, have a
     face amount of $100,000 or any other amount specified by Westpac;

(b)  be expressed to be drawn by Collins and signed by Collins as drawer;

(c)  be payable at Westpac's office at: 3rd Floor, 255 Elizabeth Street, Sydney,
     NSW 2000, or any other address which Westpac may specify;

(d)  have the name of the payee left blank;

(e)  have a term, as required by Collins of 1, 2, 3, 4, 5 or 6 months or any
     other term Westpac and Collins may agree; and

(f)  mature on a Business Day which is not later than the Expiry Date.

Collins must select terms and amounts for Bills so that the total face amount of
outstanding Bills will not at any time exceed the limit allocated to the Bill
Option.

Authority

Collins irrevocably and for value authorises Westpac:

(a)  to complete and deliver Bills under this agreement,

(b)  on behalf of Collins and in Collins's name to prepare Bills complying with
     this agreement and to sign them as drawer and if applicable, endorse them,
     and to alter any non-complying Bills.

5.   Acceptance and Discount

Acceptance and Discount

When it is obliged under this agreement to accept and discount Bills Westpac
will:

(a)  accept those Bills,

(b)  if necessary, insert as payee itself or any other person who is to buy
     those Bills, and

(c)  discount those Bills and pay to Collins or as it directs an amount equal to
     the sum of the face amount of those Bills less the sum of:

     (i)   a discount amount for each Bill which would result in a yield to
           maturity on that Bill calculated at the Discount Rate (expressed as
           a yield percent per annum),

                         (C)Westpac Banking Corporation                   Page 5

<PAGE>

                                          Collins Restaurants Management Pty Ltd

     (ii)   the acceptance fee for the Bills,

     (iii)  the preparation fee for the Bills,

     (iv)   any applicable stamp duty or other tax payable by Westpac on or in
            respect of the Bills or any payment under this agreement (including
            financial institutions duty), and

     (v)    any other amount owing by Collins to Westpac in relation to the
            Bills under this agreement.

6.   Payment Obligations

Indemnity

Collins shall indemnify Westpac on demand against all liabilities of Westpac as
acceptor or endorser of Bills.

Liability on Bills

As between Westpac and Collins, Collins is primarily liable in respect of all
Bills. Accordingly:

(a)  the liability of Collins with respect to any Bill will not be discharged
     because Westpac becomes the holder of that Bill before, on or after its
     maturity, and

(b)  not later than 11 am on the maturity date for each Bill, Collins shall pay
     to Westpac an amount equal to the face amount of that Bill.

Netting Off

Where new Bills are to be drawn and accepted on the maturity date of old Bills,
only the net amount as between the amounts payable on that date:

(a)  by Collins to Westpac under the clause headed "Payment Obligations" in
     respect of the face amount of the old Bills, and

(b)  by Westpac to Collins by way of proceeds of the new Bills under The clause
     headed "Acceptance and Discount",

need be paid.

Fees

Collins will pay fees as set out in this agreement.

                         (C)Westpac Banking Corporation                   Page 6

<PAGE>

                                          Collins Restaurants Management Pty Ltd

Repayment

The facilities provided under this agreement will terminate on the Expiry Date,
and at that time Collins will pay to Westpac:

(a)  all money owing by it to Westpac under or in connection with the facilities
     provided under this agreement, and

(b)  the face amount of all Bills then outstanding.

7.   Representations and Undertakings

Collins make the representations and give the undertakings in the Guarantee.

8.   Westpac's Remedies and Powers

Event of Default

If an Event of Default (as defined in the Guarantee) occurs then Westpac may at
any time do either or both of the following:

(a)  terminate the facilities and cancel the Commitment; and

(b)  by written notice require Collins to pay to Westpac all or some of:

     (i)  the money actually or contingently owing by it to Westpac under or in
          connection with the facilities, and

     (ii) the face amount of all Bills outstanding as at the date of that
          notice.

Collins will pay those amounts immediately.

If a notice requires the payment of only some of the amounts lent or provided or
otherwise outstanding, then Westpac may at any time by written notice require
Collins to pay further amounts, until all amounts lent or provided or actually
or contingently outstanding by Collins have been paid.

Amounts paid on unmatured Bills and contingent amounts

(a)  Any amount paid to Westpac under this clause in respect of any unmatured
     Bill or in respect of any sum contingently owing, and

(b)  interest credited under this clause,

                         (C)Westpac Banking Corporation                   Page 7

<PAGE>

                                          Collins Restaurants Management Pty Ltd

will accrue and be credited with interest at a rate and in a manner which
Westpac determines would under its normal procedures apply to deposits of a
similar amount at call (or of any other term specified by Westpac).

Westpac may apply it in or towards satisfaction of any sum at any time payable
by Collins to Westpac under or in relation to this agreement or any security
document, including in respect of Bills.

It is repayable by Westpac to the extent only that on any day it exceeds the
amount of all money owing to Westpac under or in connection with this agreement
or any security document (including, without limitation, the total face amount
of the outstanding Bills and all amounts which are then or may subsequently
become contingently owing).

Application of Money - Set-Off

If Collins does not pay an amount when due, Westpac may apply any money in any
of Collins' accounts (whether or not matured) in payment of any amount payable
under this agreement. It need not do so. It can convert currencies using its
normal procedures.

No Waiver

No failure to exercise a power, and no delay in exercising a power, operates as
a waiver. Waivers must be in writing.

9.   Payments - general provisions

Method of Payment

Collins will make all payments at the address on the first page of this
agreement or as specified by Westpac. Payments must be in cleared funds and free
of any set-off or deduction, except for taxes where required by law. All
payments will be made by 11am (local time) in the place of payment.

Time of Payment

Unless otherwise stated, amounts payable under the clauses below headed "Yield
Protection" and "Additional Payments" are payable within 2 Business Days of
demand.

Default Interest

Interest will accrue each day on each amount due but unpaid. The rate will be
Westpac's advertised Reference Lending Rate (or any equivalent rate which is
substituted for this rate from time to time) then applicable plus 2% per annum.
That interest accrues before and after any judgment.

Westpac may debit Collins's account with accrued interest under this paragraph
on any day. If it does not do so more often it will be taken to have done so
monthly. That interest will then itself bear interest.

                         (C)Westpac Banking Corporation                   Page 8

<PAGE>

                                          Collins Restaurants Management Pty Ltd

10. Yield Protection

Whenever Westpac determines that a Change in Law (as defined below) has the
effect of:

..   increasing its costs of funding or maintaining the facility, or reducing its
    return or amounts received in respect of the facility; or

..   reducing its return on capital allocated to the facility (including because
    more capital needs to be allocated to the facility or cannot be used
    elsewhere),

then Westpac will promptly notify Collins who must pay Westpac the amount
Westpac certifies is necessary to compensate it. That certificate will give an
outline of the calculation, and will be conclusive and bind Collins in the
absence of manifest error.

If Collins so requests, Westpac will negotiate in good faith with a view to
finding a means of minimising the effect, but it is not a defence that the
effect could have been avoided or minimised.

A Change in Law is the introduction of, or a change in, any law, official
directive, ruling or request or a change in its interpretation. If it does not
have the force of law, it must be one with which responsible Australian banks
would comply. Without limitation, it includes any of these circumstances which
occurs with respect to capital adequacy, special deposit, liquidity, reserve,
prime assets, tax or prudential requirements (except a change in tax on overall
net income).

11. Additional Payments

Indemnity and costs

Collins will indemnify Westpac against any liability, loss, cost or expense
(including legal costs on a full indemnity basis and including any goods and
services tax or similar tax) it incurs in or as a result of a breach of its
obligations, or actual or contemplated enforcement of this agreement and any
security for this agreement.

Collins will pay Westpac's reasonable external legal costs (including goods and
services tax or similar tax) in relation to the preparation of this agreement
and any security for this agreement, and any amendment of it, or any consent or
waiver.

Goods and Services Tax

Notwithstanding any other provision of this agreement, any amount payable to
Westpac under this agreement does not include any goods and services tax or
similar tax by whatever name called (including GST as defined in A New Tax
System (Goods and Services Tax) Act 1999, as amended from time to time, (the
"GST law")). Terms defined in the GST law have the same meaning in this
agreement.

                         (C)Westpac Banking Corporation                   Page 9


<PAGE>

                                          Collins Restaurants Management Pty Ltd

To the extent that any supply under or in connection with this agreement by
Westpac constitutes a taxable supply, the consideration payable will
automatically be increased to include an additional amount on account of GST.
That amount will be the product of the value of the consideration for the supply
and the prevailing GST rate.

Stamp Duty

Collins will pay all stamp, transaction and other similar duties and charges in
relation to this agreement, any bill of exchange made under it and any security
and any transaction under them. This includes financial institutions duty and
debits tax. Collins will also pay any fines and penalties unless they result
from a failure by Westpac to lodge a document for stamping in sufficient time,
having received from Collins the amount of stamp duty in good time.

12. General

Statements of amounts due in evidence

A written statement by Westpac as to any amount due under this agreement will be
sufficient evidence of that amount unless Collins proves it wrong.

Assignment

Collins may not assign its rights under this agreement. Westpac may transfer any
part of its rights and, with Collins' consent, obligations. Collins will not
withhold that consent unreasonably. Westpac may disclose information to a
potential transferee or sub-participant.

Where Westpac wants to transfer any part of its obligations Collins will sign
when requested by Westpac a document which will effect that transfer and which
does not increase Collins's obligations. Westpac will bear its own costs and
stamp duty on that document.

Notices

Notices, demands, statements, consents, requests, requirements and certificates
(Notices) must be in writing. Except where they instruct Westpac in relation to
a value transaction, they may be sent by facsimile, post or any other means to
the recipient's address or number set out on the signature page or any other
address or number notified to the sender by the recipient.

Notices that instruct Westpac in relation to a value transaction may only be
given by delivery of the original signed notice unless Westpac agrees otherwise.

Notices will be taken to have been given if delivered or left at that address,
on the dates on which they are delivered or left.
