Australia Pacific LNG has approved a Final Investment Decision on the second train of its CSG to LNG project …

• FID taken on the second train of the Australia Pacific LNG project (FID2)

• Marketing complete for two-train project

• Shareholdings following completion of Sinopec’s additional equity subscription: Origin 37.5%, ConocoPhillips 37.5%, Sinopec 25%

• Since FID1 in July 2011, there has been no significant change in the estimated US$20 billion project costs other than as a result of movements in foreign exchange rates, which at the time converted to A$23 billion

• The project is estimated to cost A$23 billion from FID1 to first gas from the second train

• Robust project economics

• On schedule and budget to deliver first LNG in mid-2015

• Origin and ConocoPhillips are commencing a joint process to further dilute their interests in Australia Pacific LNG

FID2 is the final condition precedent for Sinopec’s equity subscription in Australia Pacific LNG to increase to 25 per cent

(1) Assumes Origin has a 37.5% shareholding in APLNG; assumes AUD/USD exchange rate parity for subscription proceeds of US$110 per % and includes US$1.765 billion of Sinopec subscription monies paid to APLNG in August 2011 for first 15% shareholding; capital expenditure since 1 January 2011 assumes foreign exchange rates on date of shareholder cash calls and assumes 1.086 billion Origin shares on issue.

Sinopec’s additional equity subscription would value APLNG at approximately A$6.20 per Origin share(1) using a look-through valuation

• With the taking of FID2, Sinopec’s agreement to increase its shareholding in APLNG from 15% to 25% is now unconditional with completion due to occur shortly

• Origin and ConocoPhillips holdings will then each be diluted from 42.5% to 37.5%

• Shareholdings at completion: Origin (37.5%); ConocoPhillips (37.5%); Sinopec (25%)

• Sinopec’s additional equity subscription and share of capital expenditure since 1 January 2011 will result in Sinopec injecting an estimated US$2.1 billion into APLNG

• Reinforces that the export project is overseen by a strong and experienced group of shareholders in Australia Pacific LNG

The drilling rate will increase as 3rd and 4th rigs are mobilised over the coming months

(1) Excludes domestic gas sales and pre-start up LNG sales to BG. (2) Exploration & Appraisal wells and Spring Gully development wells take longer than Phase 1 Development wells due to different well

design. Above table excludes injection bores, water bores & water rigs.

• Around 1,100 operated wells to be drilled by APLNG to support ramp requirements for two trains (Phase 1)

• The key areas for drilling these Phase 1 operated wells are Talinga, Spring Gully, Condabri and Combabula

• Land access managed with 6-12 months of access agreements in place ahead of drilling

• Non-operated gas comprises around 200 TJ/day(1) (or 15%) of the estimated 1,400 TJ/day(1) gas required for a two-train project

• Current operated well deliverability is over 1 TJ per well per day on average across the Talinga and Spring Gully developments

• Phase 1 average drilling rate to date is 5.2 days/well

• The drilling activity is expected to increase as additional rigs are mobilised and commissioning is completed over coming months. A third hybrid coil drilling rig will be mobilised in Q3 CY2012 and a fourth rig is due to be mobilised before the CY 2012 year end

… to minimise financial and operational risks to the project

• Project operators are world class operators in their fields • Industry leaders engaged for all key contracts and services of the project • Integration and interfacing team established to drive alignment between

different project components • Significant front-end loading conducted prior to FID

Execution risk

• Key contracts for upstream pipeline and downstream LNG plant are predominantly fixed price, lump sum

• All major contracts are awarded • Offshore pre-fabrication & modularisation to reduce field construction hours • Appropriate contingency built into cost schedules • Dedicated commissioning team on Curtis Island

Project cost overruns & delays

• Key downstream and pipeline contracts are predominantly fixed price with labour risk passed on to the contractor

• Bechtel is managing three projects on Curtis Island and should be well placed to manage resources between projects to control costs

• Existing workforce and new infrastructure to support a growing population • Large degree of modularisation reducing construction workforce • Established upstream contractors selected with existing labour capability

Insufficient labour for project execution

• Extensive community engagement to provide accurate facts and counter misinformation in the current public debate on CSG

• Working closely and collaboratively with landowners and farmers • Strong government support on environmental and land access issues

Project capital costs remain in line with FID1 estimates …

• Estimated capital expenditure (project and non-project costs) from July 2011 until start of up Train 2 in early 2016 includes: - A$23 billion(1) project costs – in line with US dollar estimates at FID1(2) - non-project related costs(3), which will be substantially offset by revenues from future early

gas sales including domestic sales and sales to other LNG projects • Of the A$23 billion estimated project costs:

- over two thirds are denominated in AUD, with the balance primarily in USD - two thirds are fixed or unit rate contracts, the balance includes some floating rate

contracts and owners costs • A$18 billion of contracts have been awarded by APLNG to date • APLNG cost estimates announced in July 2011 already allowed headroom for cost increases in

the period to first LNG in respect of specific non-operated upstream gas fields. As a result, the recent cost increases announced by other LNG project participants are not expected to materially impact APLNG’s existing cost estimates for its two-train project assessed against information currently available from the other projects - non-operated costs are approximately 12% of APLNG’s total expenditure

(1) Based on Bloomberg forward foreign exchange rates as at 21 June 2012. (2) US$20 billion (which included US$2.5 billion of contingency) equivalent to A$23 billion at FID1 in July 2011, based on Bloomberg forward

exchange rates as at 1 December 2010. (3) Non-project costs include costs associated with the domestic operations, pre-LNG operating and maintenance costs and costs associated with

the supply of gas to third party LNG projects. (4) AUD movement not evident due to rounding to the nearest AUD billion.

… with movements in foreign exchange rates decreasing the cost quoted in AUD(4), and increasing the cost quoted in USD

• Sinopec’s additional equity subscription provides Australia Pacific LNG with a net payment of US$1.4 billion(1) for the value determined as at 1 January 2011

• Cash injection of US$2.1 billion, including Sinopec’s share of capital expenditure since 1 January 2011

• These funds will be used to meet project expenditure before any additional funding is required from Origin, ConocoPhillips or Sinopec

Origin has sufficient liquidity to fund its share of APLNG

• Origin's remaining funding requirement(1) for its 37.5% share of APLNG for the period from 1 July 2012 to first production of both LNG trains is approximately A$3.6 billion

• Origin has around A$4.6 billion(2) of undrawn debt facilities and cash, which is more than sufficient to fund its commitments to APLNG, meet short-term maturing debt obligations and maintain a prudent liquidity buffer

• Some of Origin’s debt facilities mature within the period to first gas from the second train and will be replaced as required

• Any dilution of Origin’s interest in APLNG below 37.5% will improve this funding position

• Origin and ConocoPhillips will commence a joint process to dilute their current 37.5% respective interests in APLNG

• Origin is looking to retain around a 30% stake in APLNG over the longer term

(1) After US$8.5 billion of project finance and payment of Sinopec’s additional equity subscription monies to APLNG. 37.5% interest assumes Sinopec’s 25% subscription completes.
