1.5 Designation

Each of the Original Borrower and the Agent designates this Agreement as a Finance Document.

2. CONDITIONS PRECEDENT

The provisions of Clause 3 (Transfer of Commitment) and Clause 4 (Amendment and Restatement) shall automatically be effective as of the Effective Date provided that not later than two (2) Business Days before the Effective Date, the Agent has received each of the documents listed in Schedule 1 (Conditions Precedent) in a form and substance satisfactory to it. The Agent shall notify the Obligors, the Banks and the New Bank promptly upon being so satisfied.

3. TRANSFER OF COMMITMENT

3.1 Transfer by novation

(a) On the Effective Date (whether or not a Default is continuing), the Exiting Bank shall transfer by novation all of its Commitment, rights and obligations under the Finance Documents to the New Bank, so that:

(i) the Exiting Bank shall cease to be a Bank under the Restated Agreement and its Commitment shall be reduced to zero;

(ii) the New Bank shall become a Bank under the Restated Agreement with a Commitment of A$16,000,000; and

(iii) Schedule 1 (The Banks) of the Restated Agreement shall be amended by the deletion of “National Australia Bank Limited” and its replacement by “Citibank, N.A., Sydney Branch”.

(b) The transfer by novation set out in Clause 3.1 (Transfer by novation) shall take effect on the Effective Date so that:

(i) to the extent that in Clause 3.1 (Transfer by novation) the Exiting Bank seeks to transfer by novation its rights, benefits and obligations under the Finance Documents, each of the Obligors and the Exiting Bank shall be released from further obligations towards one another under the Finance Documents and their respective rights against one another under the Finance Documents shall be cancelled (being the “Discharged Rights and Obligations”);

- 2 -

(ii) each of the Obligors and the New Bank shall assume obligations towards one another and/or acquire rights against one another which differ from the Discharged Rights and Obligations only insofar as that Obligor and the New Bank have assumed and/or acquired the same in place of that Obligor and the Exiting Bank;

(iii) the Agent, the Lead Arrangers, the New Bank and the Banks (other than the Exiting Bank) shall acquire the same rights and assume the same obligations between themselves as they would have acquired and assumed had the New Bank been a Bank with the rights and/or obligations acquired or assumed by it as a result of the transfer and to that extent the Agent, the Lead Arrangers and the Banks (including the Exiting Bank) shall each be released from further obligations to each other under the Finance Documents; and

(iv) the New Bank shall become a party to the Restated Agreement as a “Bank”.

(c) Any amounts payable to the Banks by the Obligors pursuant to any Finance Document on or before the Effective Date (including, without limitation, all interest, fees and commission payable on the Effective Date) in respect of any period ending on or prior to the Effective Date shall be for the account of the Banks (including, for the avoidance of doubt, the Exiting Bank), and the New Bank shall not have any interest in, or any rights in respect of, any such amount.

3.2 Limitation of responsibility of Existing Banks

(a) The New Bank confirms to each Bank (including, for the purposes of paragraph (i) and (ii) only, the Exiting Bank) and the other Finance Parties that it:

(i) has received a copy of the Original Credit Agreement together with such other information as it has required in connection with this transaction;

(ii) has made (and shall continue to make) its own independent investigation and assessment of the financial condition and affairs of each Obligor and its related entities in connection with its participation in this Agreement and the Restated Agreement and has not relied exclusively on any information provided to it by any Bank in connection with any Finance Document; and

(iii) will continue to make its own independent appraisal of the creditworthiness of each Obligor and its related entities whilst any amount is or may be outstanding under the Finance Documents or any Commitment is in force.

- 3 -

(b) Unless expressly agreed to the contrary, the Banks (including, for the avoidance of doubt, the Exiting Bank) make no representation or warranty and assume no responsibility to the New Bank for:

(i) the legality, validity, effectiveness, adequacy or enforceability of the Finance Documents or any other documents;

(ii) the financial condition of any Obligor;

(iii) the performance and observance by any Obligor of its obligations under the Finance Documents or any other documents; or

(iv) the accuracy of any statements (whether written or oral) made in or in connection with the Finance Documents or any other document,

and any representations or warranties implied by law are excluded.

(c) Nothing in any Finance Document obliges any Bank to:

(i) accept a re-transfer from the New Bank of any of the rights and obligations transferred by novation under this Agreement; or

(ii) support any losses directly or indirectly incurred by the New Bank by reason of the non-performance by any Obligor of its obligations under the Finance Documents or otherwise.
