meet Pipeline Pressure requirements. If these conditions precedent are not satisfied by December 31, 2004, then this Agreement will terminate (except for Clauses 17, 20

"2.2
In addition to the conditions in Clause 2.1, Buyer shall begin actual construction of the Plant by March 1, 2005, and diligently
prosecute actual construction of the Plant and the Pipeline thereafter in an orderly and prudent manner through and until the Commencement Date." 

"2.4

        3.     Authority, Effect and Governing Law. Section 20.1 (a),containing a
representation and warranty regarding Seller's and Buyer's corporate proceedings with respect to the Original Agreement, is hereby amended and replaced in its entirety as set forth below.

Percentage. 

2.3   Parties Not Released  

        No Seller shall be responsible for the obligations of any other Seller under this Agreement. Default by a Seller under its separate agreement with the Buyer shall
not release:

	any
other Seller from any of its obligations to the Buyer; or

	(b)
	the
Buyer from any of its obligations to any other Seller. 

2.4   Common Stream  

        Contract Gas delivered by the Sellers under this Agreement, may be tested, measured and delivered in a common stream, and each Seller shall be deemed to have

3.     TITLE TO CONTRACT GAS  

        The Sellers shall have title to and be in control and possession of and shall assume all risk for the Contract Gas until it is delivered to Buyer at the Delivery
Point when Buyer shall take title to and be in control and possession of and shall assume all risk for the Contract Gas so delivered. 

4.     DELIVERY  

	4.1
	All
Contract Gas to be delivered by the Sellers to the Buyer shall be delivered at the Delivery Point, where, the ownership of the Contract Gas will be transferred from the Sellers to
Buyer.

	4.2
	The
Sellers shall deliver Contract Gas to the Delivery Point at a pressure which meets the entry specifications of the Alinta Queensland Gas Pipeline at the Delivery Point.

	4.3
	The
Sellers shall use all reasonable endeavours to ensure that Contract Gas is delivered at uniform hourly rates during each Day. 

5.     SPECIFICATIONS  

	5.1
	If
any Contract Gas delivered or likely to be tendered for delivery is Off-Specification Gas:

	5.1.1
	the
Sellers, as soon as practicable after becoming aware of such non-conformity, shall notify Buyer of the non-conformity and of its cause and probable
duration, and shall take such steps as are practicable to bring all Contract Gas tendered thereafter for delivery into conformity with the Specifications; and

	5.1.2
	If
Off-Specification Gas has been tendered for delivery but not delivered, Buyer, being aware that the Contract Gas so tendered is Off-Specification Gas,

6.6   Field Failure Event  

	6.6.1
	The
Sellers acknowledge that, any interruption to supply, except as permitted under Clause 11, increases the difficulty for the Buyer to satisfy the Buyer's obligations under
its on-supply agreements.

	6.6.2
	The
Sellers will work together with the Buyer in good faith to agree on measures to be implemented prior to the Delivery Point to reduce the impact of variations of field gas output
and of failure of components of the field production, collection and compression system.

	6.6.3
	Without
limiting clause 6.6.2, the Parties agree that the following measures shall be undertaken by the Sellers to achieve the above objectives:

	6.6.3.1
	separation
of, and if necessary, duplication of parts of the gas gathering and collection system so that failure of a single pipe system does not lead to the loss of the entire
Contract Gas available for delivery;

	6.6.3.2
	arrangement
of the compressor station and the entry of the gas collection system into the compressor station to ensure that a single compressor failure does not result in loss of
ability to compress at least 50% of the Contract Gas supplied under this Agreement;

	6.6.3.3
	maintenance,
on site, of essential spare parts and appropriately skilled personnel to address contingency failures and repairs; and

	6.6.4
	The
Buyer acknowledges that these measures will require the Sellers to work with the Field Operator (where the Field Operator is not one of the Sellers). The Sellers agree to use
best endeavours to ensure that any measures agreed between the Parties are implemented by the Field Operator.

Sellers warrant that as at the date of entering into any agreement with a third party for the supply of gas from within the Contract Area, there are sufficient reserves within the
Contract Area to ensure that the Sellers are able to satisfy their obligations to all buyers of gas from the Contract Areas for the term of this Agreement.

	7.3
	Where
a Seller fails to make available for delivery to the Buyer its Ownership Percentage of Contract Gas or fails to deliver its Ownership Percentage of Contract Gas nominated by the
Buyer under this Agreement, that Seller will pay to the Buyer as liquidated damages the lesser of:

	7.3.1
	the
Contract Price multiplied by the quantity of Contract Gas not delivered; and

	7.3.2
	subject
to clause 7.4, the difference between the reasonable costs and expenses incurred by the Buyer in obtaining delivery of an alternate supply of gas (which shall include
the costs 

12

 

associated
with negotiating with third parties to secure such supply) and the amount that would have been paid to that Seller under this Agreement. 

	7.4
	In
the event that the Buyer, using reasonable endeavours is unable to secure an alternate supply of gas as contemplated by clause 7.3.2, then the Seller's liability to the
Buyer for failure to make Contract Gas available for delivery will be the Contract Price multiplied by the quantity of Contract Gas not delivered.

	7.5
	The
Sellers will pay liquidated damages calculated in accordance with clauses 7.3 or 7.4 (as applicable) within fourteen (14) Days after receipt by the Sellers of a statement
from the Buyer setting out the amount of the liquidated damages calculated in accordance with clauses 7.3 or 7.4 (as applicable).

	7.6
	The
Parties acknowledge that the amounts payable under clauses 7.3 or 7.4 (as applicable) are intended to be liquidated damages that constitute a reasonable and good faith
pre-estimate of the anticipated or actual loss or damage which would be incurred by the Buyer and not a penalty. 

8.     MEASUREMENT OF VOLUMES AND REGULATION OF PRESSURES  

	8.1
	The
Sellers shall be responsible for installing, operating and maintaining the devices for measuring the Contract Gas or for arranging for the same to be done. The quantities of

	8.2
	Any
Party may, at its own risk and expense, install check measuring and recording devices, providing they do not interfere or influence the operation of the devices installed pursuant
to clause 8.1 and providing that Party negotiates its own terms with the owner of the Alinta Queensland Gas Pipeline.

	8.3
	Each
Party or its agent shall, subject to it obtaining agreement from the owner of the Alinta Queensland Gas Pipeline, have the right to be present to observe installation, reading,
cleaning, changing, repairing, inspecting, calibrating or adjusting of the measuring and recording devices referred to in clause 8.1.

	8.4
	The
Parties agree that the provisions of Schedule 2 will govern the measurement of Contract Gas for the purposes of this Agreement. If a Party is required to take action under
an agreement which it has with another party to ensure that the requirements of Schedule 2 are met, that Party shall take all such action and do all such things as may be required to achieve
that result.

   SCHEDULE 1  

CONTRACT PRICE  

        The base Contract Price for Contract Gas shall be $[***]/GJ (exclusive of GST) as at 1 January 2005 ("Base Contract Price").

Contract Price for the period from the Commencement Date until 8.00 am on 1 January 2006 will be the base Contract Price and thereafter the Contract Price will be adjusted at
8.00 am on 1 January in each Contract Year in accordance with the following formula: 

        Contract
Price     = [BCP] *
[1 + [***](CPIn—CPIb)/CPIb] 

        where:

BCP
= Base Contract Price; 

CPIn =    the
CPI for the quarter ended the day before that first day of January in respect of which the Contract Price is being calculated 

CPIb =    the
base CPI being the CPI for the quarter ended 31 December, 2004.

Consumer Price Index as published by the Australian Bureau of Statistics for the All Groups Weighted Average of Eight Capital Cities or its successor
index in the event that this is modified. 

        Contract
Price units are to be calculated to two (2) decimal places of a cent. Where the third decimal place is a value of five (5) or greater the second decimal unit is to
be rounded up and where it is less than five (5) it is to be rounded down. 

        Should
the Consumer Price Index be abolished or abandoned, no longer published, or its basis for calculation changed in a material respect then the Parties agree to meet in good faith to
agree upon a similar index as a substitute and, failing agreement, the matter shall be referred to dispute resolution in accordance with clause 22.
