See Condition 5.6 of “Terms and Conditions of the Notes” for further detail.

RISK FACTORS A9.3.1 A13.2 Each of the Issuer and the Guarantor believes that the following factors may affect its ability to fulfil its obligations under the Notes. All of these factors are contingencies which may or may not occur and neither the Issuer nor the Guarantor is in a position to express a view on the likelihood of any such contingency occurring.

In addition, factors that are material for the purpose of assessing the market risks associated with the Notes are described below.

Each of the Issuer and the Guarantor believes that the factors described below represent the principal risks inherent in investing in the Notes, but the inability of the Issuer or the Guarantor to pay interest, principal or other amounts on or in connection with the Notes may occur for other reasons which may not be considered significant risks by the Issuer and the Guarantor based on information currently available to them or which they may not currently be able to anticipate. Prospective investors should also read the detailed information set out elsewhere in this Prospectus and reach their own views prior to making any investment decision.

Please refer to “Description of the Guarantor” and “Glossary” for definitions of terms used but not otherwise defined in this section.

Factors that may affect the Issuer’s ability to fulfil its obligations under the Notes and the Guarantor’s ability to fulfil its obligations under the Guarantee The risk factors described below apply in the context of the Guarantor and the Group and are also applicable to the Issuer.

Finance vehicle

The Issuer is a finance vehicle and acts as the principal finance company for the Group. The Issuer’s sole business is raising debt to be on-lent to companies within the Group and to fund their investment programmes and to manage cash generated from Group operations. Accordingly, substantially all the assets of the Issuer are loans and advances made to other members of the Group. The ability of the Issuer to satisfy its obligations in respect of the Notes will depend upon payments made to it by other members of the Group in respect of loans and advances made by it.

Volatility in oil and gas prices

The Guarantor’s business relies primarily on the production and sale of oil and gas products (including LNG) to a variety of buyers under a range of short-term and long-term contracts. International oil and gas prices have fluctuated widely in recent years and may continue to fluctuate significantly in the future. The Guarantor cannot predict future oil and gas prices.

Demand for, and pricing of, LNG remains sensitive to external economic and political factors, including crude oil prices and buyer preferences as between LNG and oil. Crude oil prices are affected by numerous factors beyond the Guarantor’s control, including worldwide oil supply and demand, the level of economic activity in the markets that the Guarantor serves, regional political developments and military conflicts in oil producing countries and regions (in particular, the Middle East), the weather, the ability of the Organization of the Exporting Countries (OPEC) and other producing nations to influence global production levels and prices, the price and availability of new technology and the availability and cost of alternative sources of energy. The international price for crude oil has historically been volatile. Accordingly, it is impossible to predict future crude oil price movements with certainty.

Fluctuations in the global oil and global and domestic gas market, in particular, any extended or substantial decline in oil and gas prices or demand for oil and gas, may materially affect the Guarantor’s financial condition and results of operations. Increases and decreases in oil and gas prices affect the amount of cash flow available for capital expenditure and the Guarantor’s ability to borrow money or raise additional

10 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS capital. Lower oil and gas prices may also reduce the amount of oil and natural gas that the Guarantor can produce economically.

LNG supply contracts

The Guarantor’s market share of LNG supply contracts and, therefore, its profits may be adversely affected by the introduction of new LNG facilities and the expansion, by the Guarantor’s competitors, of their existing LNG facilities in the global LNG market. Such new facilities or expansion of existing facilities could increase the global supply of LNG, thereby potentially lowering the price of LNG.

Replacement of existing reserves

The Guarantor’s future long-term results are directly related to the success of efforts to replace existing oil and gas reserves as they are utilised, either through exploration or acquisition. In general, the volume of production from oil and gas properties declines as reserves are depleted, although the rate of decline depends on the characteristics of a particular reserve. The Guarantor’s reserves will decline as they are utilised unless the Guarantor acquires properties with proved reserves or conducts successful exploration and development activities. The Guarantor’s aim is to continue to replace its utilised reserves but given that exploration is a high risk endeavour subject to geological, technological and environmental hazards and that there is no certainty that acquisitions will continue to be made, no assurance can be given that the Guarantor will be able to continue to replace its utilised reserves with additional proved reserves.

Acquisition and divestment activities A.9.4.1.5

The Guarantor from time to time evaluates acquisition and divestment opportunities across its range of assets and businesses. Any acquisitions or disposals would lead to a change in the sources of the Guarantor’s earnings and result in variability of earnings over time. Any acquisitions or disposals could also lead to changes in future capital and operating expenditure obligations which may impact the Guarantor’s funding requirements. They may also give rise to liabilities. Integration of new businesses into the Santos group may be costly and may occupy a large amount of management’s time. There is no certainty that the Guarantor will complete any acquisition or divestment that it has entered into, including the sale of its Evans Shoal interests to Magellan announced on 26 March 2010. On 9 September 2010, the Guarantor announced the sale of a 15 per cent. interest in the GLNG Project to Total E&P Australia which is subject to certain customary conditions including the approval of the Australian Foreign Investment Review Board. While it is expected that these conditions will be satisfied to allow completion to occur, there is no certainty that such approvals will be forthcoming and a failure to complete this sale would have an adverse impact on the Guarantor’s future funding requirements. The Guarantor has also announced the possibility of a further sell down of an interest in the GLNG Project, but there is no certainty that it will be successful in doing so.

Projects risks

The Guarantor is investing a significant amount of capital in the PNG LNG and GLNG Projects. These and other projects may be delayed or be unsuccessful for many reasons, including unanticipated financial, operational or political events, the failure to receive state and federal government environmental and other approvals, whether a final investment decision is reached, cost overruns, decline in LNG prices or demand, equipment and labour shortages, technical concerns including possible reserves and deliverability difficulties, environmental and water disposal impacts, increases in operating cost structures, contractual issues associated with GLNG upstream joint venture alignment or with major engineering procurement and construction contracts, community or industrial actions or other circumstances which may result in the delay, suspension or termination of the projects, the total or partial loss of the investment and a material adverse effect on the Guarantor’s business, results of operations, financial condition and credit rating.

In addition, sales contracts with various counterparties are expected to be entered into in relation to the PNG LNG and GLNG projects. The ability of the counterparties to meet their commitments under such an arrangement may impact on the Guarantor’s investment in these projects.

11 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS

Project developments in which the Guarantor is, or may become, involved are subject to risks, including technical risk. Changes in reserves, liquids and gas prices, exchange rates, construction costs, design requirements and delays in construction may adversely affect the commerciality and economics of project development.

Operational risk

Industrial disputes, work stoppages and accidents, natural disasters, drilling and production results, reserve estimates, environmental impacts and other factors all contribute towards operational risk which may have an adverse effect on the Guarantor’s profitability and results of operations. Appropriate insurance can only provide protection for some, but not all, of the costs that may arise from unforeseen events.

Counterparty risk

As part of its ongoing commercial activities, the Guarantor enters into sales contracts with various third parties for the sale of natural gas, LNG and other products. If any counterparty were unable to meet its commitments to the Guarantor under such contracts, in whole or in part, and if there is no form of security in place, there is a risk that future anticipated revenues would reduce unless and until the Guarantor was able to secure an alternative customer. Therefore, such failure of a counterparty to a sales contract could materially and adversely affect the Guarantor’s financial condition and credit rating. Counterparty risk also arises when the Guarantor enters into contracts for committed lines of credit and derivatives with financial institutions. The Guarantor’s risk to counterparty credit risk is reduced by the implementation of credit policies that apply to sales contracts, banking arrangements and derivative contracts.

Currency risk

The functional and presentational currency of the Guarantor is the Australian dollar. Some subsidiaries have a functional currency of U.S. dollars and the results of their operations are translated into Australian dollars. The Guarantor may incur expenditure in the local currencies of the countries in which it operates or in other currencies for supplies of materials and services. The Guarantor is exposed to foreign exchange rate fluctuations in the Australian dollar value of foreign currency-denominated revenues, expenses, assets and liabilities. Accordingly, a change in the value of the Australian dollar relative to the relevant local currency and/or U.S. dollar may have an effect on the net asset value and profit and loss of the Guarantor in Australian dollars.

Market risk

The Guarantor borrows money domestically and internationally on interest rates that are either fixed or floating. A rise in interest rates, either domestically or internationally, would affect the Guarantor’s cost of borrowing and would adversely affect its business and financial condition.

The Guarantor, from time to time, hedges some of its commodity price, exchange rate and interest rate risks. While such hedging activities may provide downside risk protection for the Guarantor, it is also possible such activities may limit its upside benefit potential or give rise to additional losses. The management of interest rate risk, foreign exchange risk and commodity risks are governed by treasury policies which are approved by the Board of the Guarantor.

Access to capital

The Guarantor’s business and, in particular, development of large scale projects, relies on access to debt and equity financing. The Guarantor’s ability to secure financing, or financing on acceptable terms may be materially adversely affected by volatility in the financial markets, globally or affecting a particular geographic region, industry or economic sector, or by a downgrade in its credit rating (the Guarantor is currently rated BBB+ by S&P). For these or other reasons, financing may be unavailable or the cost of financing may be significantly increased. Such inability to obtain, or increase to the costs of obtaining, financing could materially and adversely affect the Guarantor’s business, results of operations and financial condition.

12 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS

Mineral Resources Rent Tax and other Australian taxes

In addition to the standard level of income tax imposed on all industries, companies in the petroleum and gas industries are required to pay government royalties, direct and indirect taxes and other imposts in the jurisdictions in which they operate. The profitability of companies in these industries can be affected by changes in government taxation and royalty policies or in the interpretation or application of such policies. On 2 July 2010, the Australian Labor government announced that it intends to introduce a Minerals Resource Rent Tax (MRRT) and an expanded Petroleum Resource Rent Tax (PRRT) from 1 July 2012. The existing PRRT regime applies to offshore oil and gas projects. The MRRT was stated to be intended to apply to iron ore and coal in Australia, with all other minerals excluded, whilst the expanded PRRT was stated to be intended to apply to onshore and offshore oil, gas and coal seam methane projects. The recent Australian federal election on 21 August 2010 initially produced an inconclusive result as neither major party was able to secure the requisite number of seats in the House of Representatives to form a government in its own right. On 7 September 2010, the Australian Labor Party secured the support of a further two independent members of Parliament such that it had the requisite backing to form a minority government. Accordingly, it is unclear whether and to what extent the MRRT and expanded PRRT will be implemented. Further, assuming implementation, exact details concerning the proposed changes to the tax regime remain uncertain and the extent to which they may impact on the Guarantor and/or its operations is yet to be determined. The possible introduction of the expanded PRRT has the potential to increase the Guarantor’s effective tax rate, which could adversely affect the Guarantor’s financial performance, financial position, cash flows and share price.

Environmental risk

Oil and gas exploration and production is an environmentally hazardous activity which may give rise to substantial costs for environmental rehabilitation, damage control and losses.

With increasingly heightened government and public sensitivity to environmental sustainability, environmental regulation is becoming more stringent. The Guarantor could be subject to increasing environmental responsibility and liability, including laws and regulations dealing with air quality, water and noise pollution and other discharges of materials into the environment, plant and wildlife protection, the reclamation and restoration of certain of its properties, greenhouse gas emissions, the storage, treatment and disposal of wastes and the effects of its business on the water table and groundwater quality.

Sanctions for non-compliance with these laws and regulations may include administrative, civil and criminal penalties, revocation of permits, reputational issues, increased licence conditions and corrective action orders. These laws sometimes apply retroactively. In addition, a party can be liable for environmental damage without regard to that party’s negligence or fault.

Increased costs associated with regulatory compliance and/or with litigation could have a material and adverse effect on the Guarantor’s earnings and cash flows.

Carbon emissions

There is growing recognition that greenhouse gas emissions potentially contribute to global warming, greenhouse effects and climate change. A number of governments or governmental bodies, including those in Australia, have introduced, or are contemplating, regulatory change in response to the potential impacts of climate change and greenhouse gas emissions.

The Australian Labor government, under former Prime Minister Kevin Rudd, proposed a national emissions trading scheme (the Carbon Pollution Reduction Scheme (CPRS)). The proposed CPRS would require certain carbon emitters to purchase permits which reflect their emissions volume, subject to price caps. If the CPRS is introduced in the form previously proposed (which is not certain), the Guarantor may be exposed to additional operating costs which will have an adverse impact on its financial performance. The CPRS legislation was not passed by the Australian parliament. On 27 April 2010, the Australian Labor government announced the delay of the implementation of the CPRS until after the end of the current commitment period of the Kyoto Protocol, at the end of 2012, or until the domestic and international

13 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS political circumstances improve. In the lead up to the recent federal election, the Australian Labor Party maintained its commitment to a CPRS following that delay, but also proposed further public consultation measures. The Coalition (comprised of a coalition of the centre-right Liberal Party of Australia and the centre-right National Party of Australia) has proposed an alternative ‘direct action’ approach. The Australian Greens support stronger responses. A carbon tax is a further alternative, including as an interim measure before an emissions trading scheme operates. Likely global action is also uncertain. The recently formed minority Labor government has announced the formation of a Climate Change Committee, which will encompass experts and parliamentary representatives. The Climate Change Committee will explore options for the implementation of a carbon price and is designed to help build a consensus on how Australia will address the challenge of climate change. Although the precise terms of any potential legislation are unclear, from a medium and long-term perspective, the regulation of greenhouse gas emissions is likely to become more stringent and there are likely to be changes in the returns on the Guarantor’s greenhouse gas-intensive assets and energy-intensive assets as a result of regulatory impacts on the industry in which the Guarantor operates. It will depend on, among other things, the final form of greenhouse gas emissions regulation, commercial arrangements, energy efficiency, the development of low emissions technology and the carbon price. Until the final form of greenhouse gas emissions regulation is known, the impact on the Guarantor’s business, results of operations and financial condition is uncertain.

Government actions and regulatory risk The Guarantor’s business is subject to various national and local laws and regulations, in each of the countries in which it operates, relating to the development, production, marketing, pricing, transportation and storage of its products. A change in the laws which apply to the Guarantor’s business or the way in which it is regulated could have a material adverse effect on its business, results of operations and financial condition. Other changes in the regulatory environment (including applicable accounting standards) may have a material adverse effect on the carrying value of material assets or otherwise have a material adverse effect on the Guarantor’s business, results of operations and financial condition. The Guarantor’s operations could also be affected by government actions in Australia and other countries or jurisdictions in which it has interests. These actions include government legislation, government approvals, guidelines and regulations in relation to the environment, the petroleum and gas industries, competition policy, native title and cultural heritage. Such actions could impact on land access, the granting of licences and other petroleum and gas interests, the approval of developments and freedom to conduct operations. The possible extent of introduction of additional legislation, regulations, guidelines or amendments to existing legislation that might affect the Guarantor’s business is difficult to predict. Any such government action may require increased capital or operating expenditures and could prevent or delay certain operations by the Guarantor, which could have a material adverse effect on the Guarantor’s business and financial condition.

Political risk The Guarantor is subject to a risk that it may not be able to carry out its operations as it intends to or enter into new operations, nor ensure the security of its assets. In addition, it is subject to risks of, among other things, loss of revenue, property and equipment as a result of hazards such as expropriation, border and territorial disputes, war, insurrection and acts of terrorism and other political risks and increases in taxes and government royalties. The Guarantor has operations outside Australia in , Kyrgyz Republic, , , , and Timor-Leste.

The Guarantor’s interests are subject to political, economic, social and other uncertainties, including the risk of civil rebellion, expropriation, nationalisation, land ownership disputes, renegotiation or termination of existing contracts, licences and permits or other agreements, changes in laws or taxation policies, currency exchange restrictions and changing political conditions. The effects of these factors are difficult to predict

14 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS and any combination of one or other of the above may have a material adverse effect on the operation or development of the Guarantor’s business and even render it uneconomic.

Joint venture risk

The Guarantor’s business is carried out through joint ventures. Some of these joint venture assets are managed and operated by the Guarantor or its subsidiaries, and some are “non-operated” (that is, managed and operated by other international and domestic exploration and production companies). The use of joint ventures is common in the exploration and production industry and serves to mitigate the risk and associated cost of exploration, production and operational failure. However, failure of agreement or alignment with joint venture partners or the failure of third party joint venture operators could have a material effect on the Guarantor’s business. The failure of joint venture partners to meet their commitments and share of costs and liabilities can result in increased costs to the Guarantor.

Land resource and tenure

The Guarantor has investments and operations in several countries where title to land and access and other rights with respect to land and resources (including indigenous title) may be complex and unclear. From time to time, these complexities and uncertainties can result in disputes with local groups and/or parties representing local interests. The outcome of these disputes may have an adverse impact on the Guarantor’s assets (including its ability to develop these assets) in the relevant jurisdictions. A number of the Guarantor’s Australian interests are located within areas which are the subject of one or more claims or applications for native title determinations. The Guarantor does not believe that the outcome of those claims or applications will significantly impact on its asset base, however, native title decisions have the potential to introduce royalty payments and delay in the grant of mineral and petroleum tenements and other licences and consequently may impact generally on the timing of exploration, development and productions operations.

Banjar Panji-1 Well Incident

In May 2006, a non-toxic mudflow incident occurred at the Banjar Panji-1 Well near Surabaya, East Java. The incident resulted in significant property damage, the interruption of local infrastructure and the need to relocate a significant number of local villages. In December 2008, the Guarantor’s subsidiary (Santos Brantas) transferred its 18 per cent. non-operating interest in the project to Minarak Labuan Co (L) Ltd (Minarak), with approval from the relevant Indonesian regulator. The transaction also included a release from the remaining joint venturers in the project from all liability (if any) to them in relation to the project and the mudflow incident. However, the transaction did not release Santos Brantas from liability to third parties. There are currently no third party claims pending and no matters have come to the Guarantor’s attention to indicate that a third party has or is likely to claim against Santos Brantas in respect of the incident. Consistent with the Guarantor’s view that the chance of a third party claim being made is unlikely and, if such a claim were made, it would be able to successfully defend those claims, no provision for any future costs in relation to the incident and no contingent liability disclosures were made in the Guarantor’s 30 June 2010 financial statements.

Key Personnel

The Guarantor’s future success depends on the expertise and continued service of certain key executives and technical personnel. Although the Guarantor enters into employment and incentive arrangements with such personnel to secure their services, the Guarantor cannot guarantee the retention of their services. Should key personnel leave, the Guarantor’s business, its results of operations and financial condition may be adversely affected.

Estimates of oil and gas resources are uncertain

Calculations of recoverable oil and gas resources contain significant uncertainties, which are inherent in the reservoir geology, the seismic and well data available and other factors such as project development and operating costs, together with commodity prices. This uncertainty is often expressed as a range of resource

15 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS levels with associated probabilities. During the course of appraisal, development and continuing operations, the increased quantity and variety of data will generally improve the accuracy of the resource estimate and narrow the range of uncertainty. However, in some cases the stated reserves may move significantly away from the previous estimates, either upwards or downwards.

Exploration and production licences may be withdrawn

The Guarantor’s exploration and prospective production are dependent upon the granting and maintenance of appropriate licences, permits and regulatory consents (authorisations) which may not be granted or may be withdrawn or made subject to limitations at the discretion of, inter alia, government or regulatory authorities. Although the authorisations may be renewed following expiry or granted (as the case may be), there can be no assurance that such authorisations will be continued, renewed or granted or as to the terms of such renewals or grants. Moreover, if the Guarantor does not meet its work and/or expenditure obligations under permits and licences, this may lead to dilution of its interest in, or the loss of, such permits and licences.

Factors which are material for the purpose of assessing the market risks associated with the Notes The Notes may not be a suitable investment for all investors

Each potential investor in the Notes must determine the suitability of that investment in light of its own circumstances. In particular, each potential investor should:

(i) have sufficient knowledge and experience to make a meaningful evaluation of the Notes, the merits and risks of investing in the Notes and the information contained in this Prospectus or any applicable supplement;

(ii) have access to, and knowledge of, appropriate analytical tools to evaluate, in the context of its particular financial situation, an investment in the Notes and the impact the Notes will have on its overall investment portfolio;

(iii) have sufficient financial resources and liquidity to bear all of the risks of an investment in the Notes, including where the currency for principal or interest payments is different from the potential investor’s currency;

(iv) understand thoroughly the terms of the Notes and be familiar with the behaviour of any relevant financial markets; and

(v) be able to evaluate (either alone or with the help of a financial adviser) possible scenarios for economic, interest rate and other factors that may affect its investment and its ability to bear the applicable risks.

The Notes are complex investment securities. Sophisticated institutional investors generally do not purchase complex investment securities as stand-alone investments. They purchase complex investment securities as a way to reduce risk or enhance yield with an understood, measured, appropriate addition of risk to their overall portfolios. A potential investor should not invest in the Notes unless it has the expertise (either alone or with a financial adviser) to evaluate how the Notes will perform under changing conditions, the resulting effects on the value of the Notes and the impact this investment will have on the potential investor’s overall investment portfolio.

The Notes are subordinated obligations

The Notes will be subordinated obligations of the Issuer and the Notes will rank pari passu with each other in a winding-up of the Issuer. Upon the occurrence of any winding-up proceedings of the Issuer, payments on the Notes will be subordinated in right of payment to the prior payment in full of all other liabilities of the Issuer, except for obligations which rank equally with the Notes.

16 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS

Similarly, the Guarantor’s obligations under the Guarantee are subordinated obligations of the Guarantor. Upon the occurrence of any winding-up proceedings of the Guarantor, the Guarantor’s obligations under the Guarantee will be subordinated in right of payment to the prior payment in full of all other liabilities of the Issuer, except for obligations which rank equally with the Guarantee.

Holders of the Notes are advised that unsubordinated liabilities of the Issuer or the Guarantor may also arise out of events that are not reflected on the balance sheet of the Issuer or the Guarantor (as the case may be), including, without limitation, the issuance of guarantees on an unsubordinated basis. Claims made under such guarantees will become unsubordinated liabilities of the Issuer or the Guarantor (as the case may be) that in a winding-up of the Issuer or the Guarantor (as the case may be) will need to be paid in full before the obligations under the Notes or the Guarantee (as the case may be) may be satisfied.

Under certain conditions, interest payments under the Notes must be deferred

If there is a Trigger Event and the S&P Rating Criteria is satisfied, the Issuer will be obliged to defer interest payments whilst that Trigger Event is continuing (as defined and further described in Condition 4.3 of “Terms and Conditions of the Notes“). Deferred Interest Payments will only be satisfied in certain circumstances (as set out in Condition 4.4 of “Terms and Conditions of the Notes”). While the deferral of interest payments continues, the Issuer may make payments on any instrument ranking senior, pari passu or subordinated to the Notes.

Any deferral of interest payments will likely have an adverse effect on the market price of the Notes. In addition, as a result of the interest deferral provision of the Notes, the market price of the Notes may be more volatile than the market prices of other debt securities on which interest accrues that are not subject to such deferrals and may be more sensitive generally to adverse changes in the Issuer’s financial condition.

The Notes are long-dated securities

The Notes will mature on the Floating Interest Payment Date falling in September 2070 and, although the Issuer may redeem the Notes in certain circumstances prior to such date, the Issuer is under no obligation to do so. Further, the Issuer and the Guarantor have entered into a replacement capital covenant (as described in “General Information“) which may limit the circumstances in which the Issuer may choose to redeem the Notes. The Holders have no right to call for the redemption of Notes except in the limited circumstances following a Change of Control Event (as set out in Condition 5.7 of “Terms and Conditions of the Notes”). Holders can only declare the Notes due and payable in certain circumstances relating to payment default and insolvent winding-up of the Issuer or the Guarantor (see Condition 10 of “Terms and Conditions of the Notes“). Therefore, Holders should be aware that they may be required to bear the financial risks associated with an investment in long-term securities.

The Issuer may redeem the Notes under certain circumstances

Holders should be aware that the Notes may be redeemed at the option of the Issuer (in whole but not in part) at their Principal Amount (plus any accrued and outstanding interest and any outstanding Deferred Interest Amounts) on 22 September 2017 or on any Floating Interest Payment Date thereafter. The Notes are also subject to redemption (in whole but not in part) at the Issuer’s option upon the occurrence of a Gross-Up Event, Change of Control Event, Tax Event, Capital Event or Accounting Event (each as defined in Condition 5 of “Terms and Conditions of the Notes”) or if the Issuer, the Guarantor and/or any Wholly Owned Subsidiary of the Guarantor has, individually or in aggregate, purchased (and not resold) or redeemed Notes and/or Original Notes equal to or in excess of 80 per cent. of the aggregate Principal Amount of the Original Notes issued on the Original Issue Date. The relevant redemption amount may be less than the then current market value of the Notes.

No limitation on issuing senior or pari passu securities

There is no restriction on the amount of securities or other liabilities which the Issuer or the Guarantor may issue or incur and which rank senior to, or pari passu with, the Notes or the Guarantee (as the case may be). The issue of any such securities or the incurrence of any such other liabilities may reduce the amount

17 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS

(if any) recoverable by Holders on a winding-up of the Issuer or the Guarantor (as the case may be) and/or may increase the likelihood of a deferral of Interest Payments under the Notes.

Fixed rate securities have a market risk

The Notes will bear interest at a fixed rate until 22 September 2017. A holder of a security with a fixed interest rate is exposed to the risk that the price of such security falls as a result of changes in the current interest rate on the capital market (the Market Interest Rate). While the nominal interest rate of a security with a fixed interest rate is fixed during the life of such security or during a certain period of time, the Market Interest Rate typically changes on a daily basis. A change of the Market Interest Rate causes the price of such security to change. If the Market Interest Rate increases, the price of such security typically falls. If the Market Interest Rate falls, the price of a security with a fixed interest rate typically increases. Investors should be aware that movements of the Market Interest Rate can adversely affect the price of the Notes and can lead to losses for the Holders if they sell the Notes.

Floating rate securities may suffer a decline in interest rate

If not previously redeemed, from 22 September 2017 until their redemption the Notes will bear interest at a floating rate. A holder of a security with a floating interest rate is exposed to the risk of fluctuating interest rate levels and uncertain interest income. Fluctuating interest rate levels make it impossible to determine the yield of such securities in advance.

Risks related to the Notes generally Set out below is a brief description of certain risks relating to the Notes generally:

Modification, waivers and substitution

The Terms and Conditions of the Notes and the Trust Deed contain provisions for calling meetings of Noteholders to consider matters affecting their interests generally. These provisions permit defined majorities to bind all Noteholders including Noteholders who did not attend and vote at the relevant meeting and Noteholders who voted in a manner contrary to the majority.

The Terms and Conditions of the Notes also provide that the Trustee may, without the consent of Noteholders, agree to (i) any modification of, or to the waiver or authorisation of any breach or proposed breach of, any of the provisions of Notes or (ii) determine without the consent of the Noteholders that any Event of Default or Potential Event of Default shall not be treated as such or (iii) the substitution of the Guarantor or a subsidiary of the Guarantor as principal debtor under any Notes in place of the Issuer, in the circumstances described in Conditions 14 and 15 of “Terms and Conditions of the Notes“.

Change of law

The Terms and Conditions of the Notes are based on laws in effect as at the date of this Prospectus. No assurance can be given as to the impact of any possible judicial decision or change to relevant law or administrative practice after the date of this Prospectus.

Denominations involve integral multiples: definitive Notes

The Notes have denominations consisting of a minimum of €50,000 plus one or more higher integral multiples of €1,000. It is possible that the Notes may be traded in amounts that are not integral multiples of €50,000. In such a case a holder who, as a result of trading such amounts, holds an amount which is less than €50,000 in his account with the relevant clearing system at the relevant time may not receive a definitive Note in respect of such holding (should definitive Notes be printed) and would need to purchase a principal amount of Notes such that its holding amounts to €50,000.

If definitive Notes are issued, holders should be aware that definitive Notes which have a denomination that is not an integral multiple of €50,000 may be illiquid and difficult to trade.

18 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:28 – eprint6 – 4278 Section 01

RISK FACTORS

Risks related to the market generally Set out below is a brief description of the principal market risks, including liquidity risk, exchange rate risk and credit risk:

The secondary market generally

Any pre-existing trading market for the Notes may not be maintained. Additionally, any such market may not be very liquid. Illiquidity may have a severely adverse effect on the market value of the Notes. Investors may not be able to sell their Notes easily or at prices that will provide them with a yield comparable to similar investments that have a developed secondary market.

Exchange rate risks and exchange controls

The Issuer will pay principal and interest on the Notes, and the Guarantor will make any payments under the Guarantee, in euro. This presents certain risks relating to currency conversions if an investor’s financial activities are denominated principally in a currency or currency unit (the Investor’s Currency) other than euro. These include the risk that exchange rates may significantly change (including changes due to devaluation of the euro or revaluation of the Investor’s Currency) and the risk that authorities with jurisdiction over the Investor’s Currency may impose or modify exchange controls. An appreciation in the value of the Investor’s Currency relative to euros would decrease (1) the Investor’s Currency-equivalent yield on the Notes, (2) the Investor’s Currency equivalent value of the principal payable on the Notes and (3) the Investor’s Currency equivalent market value of the Notes.

Government and monetary authorities may impose (as some have done in the past) exchange controls that could adversely affect an applicable exchange rate. As a result, investors may receive less interest or principal than expected, or no interest or principal.

Credit ratings may not reflect all risks

S&P have assigned a credit rating to the Notes. The rating may not reflect the potential impact of all risks related to structure, market, additional factors discussed above, and other factors that may affect the value of the Notes. A credit rating is not a recommendation to buy, sell or hold securities and may be revised or withdrawn by the rating agency at any time.

Legal investment considerations may restrict certain investments

The investment activities of certain investors are subject to investment laws and regulations, or review or regulation by certain authorities. Each potential investor should consult its legal advisers to determine whether and to what extent (1) the Notes are legal investments for it, (2) the Notes can be used as collateral for various types of borrowing and (3) other restrictions apply to its purchase or pledge of the Notes. Financial institutions should consult their legal advisers or the appropriate regulators to determine the appropriate treatment of the Notes under any applicable risk-based capital or similar rules.

TERMS AND CONDITIONS OF THE NOTES

The following, subject to alteration, are the terms and conditions of the Notes which will be endorsed on each Note in definitive form (if issued).

TERMS AND CONDITIONS OF THE NOTES

(b) When interest is required to be calculated in respect of a period of less than a full half-year, it shall be calculated on the basis of (a) the actual number of days in the period from and including the date from which interest begins to accrue (the Accrual Date) to but excluding the date on which it falls due divided by (b) the actual number of days from and including the Accrual Date to but excluding the next following Interest Payment Date multiplied by two.

4.2 Floating Interest Periods

Unless previously redeemed in accordance with these Conditions and subject to the further provisions of this Condition 4, interest on the Notes will be paid from and including the Optional Redemption Date to, but excluding, the calendar day of redemption of the Notes as follows:

(a) The Notes will bear interest at a rate determined by the Interest Calculation Agent pursuant to Condition 4.2(d) below, payable quarterly in arrear on each Floating Interest Payment Date.

(b) If any Floating Interest Payment Date would otherwise fall on a calendar day which is not a Business Day, the Floating Interest Payment Date will be postponed to the next calendar day which is a Business Day unless it would thereby fall into the next calendar month, in which case the relevant Floating Interest Payment Date will be the immediately preceding Business Day.

(c) The rate of interest for each Floating Interest Period (the Floating Rate of Interest) will, except as provided below, be the offered quotation (expressed as a percentage rate per annum) for three-month deposits in euro for that Floating Interest Period which appears on the Screen Page as of 11.00 a.m. (Central European Time) on the Interest Determination Date, plus the Floating Margin, all as determined by the Interest Calculation Agent.

If the Screen Page is not available or if no such quotation is available, the Interest Calculation Agent will request each of the Reference Banks selected by the Issuer to provide the Interest Calculation Agent with its offered quotation (expressed as a percentage rate per annum) for the relevant Floating Interest Period in an amount that is representative for a single transaction in the relevant market at the relevant time to leading banks in the interbank market of the participating Member States in the third stage of the Economic and Monetary Union, as contemplated by the Treaty on the Functioning of the European Union, for three-month deposits in euro. The offered quotations will be those offered at approximately 11.00 a.m. (Central European Time) on the relevant Interest Determination Date. As long as two or more of the selected Reference Banks provide the Interest Calculation Agent with such offered quotations, the relevant Floating Rate of Interest for such Floating Interest Period will be the arithmetic mean of such offered quotations (rounded if necessary to the nearest one thousandth of a percentage point, with 0.0005 being rounded upwards), plus the Floating Margin, all as determined by the Interest Calculation Agent.

If the Floating Rate of Interest cannot be determined in accordance with the foregoing provisions, the Floating Rate of Interest will be the offered quotation on the Screen Page, as described above, on the last calendar day preceding the Interest Determination Date on which such quotation was displayed, plus the Floating Margin, all as determined by the Interest Calculation Agent.

Floating Margin means 6.851 per cent. per annum.

(d) The Interest Calculation Agent will, on or as soon as practicable after each Interest Determination Date, determine the Floating Rate of Interest for each Note and calculate the amount of interest payable per Note for the relevant Floating Interest Period (the Floating Interest Amount). Each Floating Interest Amount will be calculated by multiplying the Floating Rate of Interest by the Day Count Fraction and the Principal Amount per Note and rounding the resulting figure to the nearest cent (with 0.5 or more of a cent being rounded upwards).

Day Count Fraction means, in respect of the calculation of the Floating Interest Amount for any Floating Interest Period, or part thereof, the actual number of calendar days in that period divided by 360.

(e) The Interest Calculation Agent will cause the Floating Rate of Interest, the Floating Interest Amount for each €1,000 in principal amount of Notes for each Floating Interest Period, the relevant Floating Interest Payment Date, and each Floating Interest Period (as the case may be), to be notified to the Issuer, the Guarantor and the Trustee promptly and, if required by the rules of any stock exchange on which the Notes are listed from time to time, to be notified to such stock exchange and to the Noteholders in accordance with Condition 13 without undue delay, but, in any case, not later than on the fourth Business Day after their determination.

4.3 Mandatory Deferral of Interest Payments

(a) If, on any day which is 8 Business Days prior to any Interest Payment Date, a Trigger Event exists and the Issuer fulfils the S&P Rating Criteria, the Interest Amount falling due on such Interest Payment Date will not be due and payable or be paid until the relevant Payment Reference Date and will constitute a Deferred Interest Payment. Interest will accrue on each Deferred Interest Payment for so long as such Deferred Interest Payment remains outstanding at the same rate of interest as the Principal Amount of the Notes bears at such time and will be added to such Deferred Interest Payment (and thereafter bear interest accordingly) on each Interest Payment Date. Each Deferred Interest Payment and interest thereon will be payable in accordance with Condition 4.4.

(b) The Issuer will notify the Noteholders (in accordance with Condition 13.1), the Trustee and the Principal Paying Agent of the existence of the Trigger Event not less than 5 Business Days prior to the relevant Interest Payment Date.

5.5 Early Redemption Amount

The Early Redemption Amount will be calculated by the Calculation Agent on the Redemption Calculation Date as the greater of the Principal Amount of the Notes and the Make-Whole Amount of the Notes, in each case plus interest accrued thereon until (but excluding) the relevant Early Redemption Date and any outstanding Deferred Interest Payments (including any amount of interest accrued thereon in accordance with Condition 4.3), where:

The Adjusted Comparable Yield will be equal to the yield at the Redemption Calculation Date on the euro- denominated benchmark security selected by the Calculation Agent, after consultation with the Issuer, as having a maturity comparable to the remaining term of the Notes to the Optional Redemption Date that would be utilised, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Optional Redemption Date.

The Make-Whole Amount will be calculated by the Calculation Agent, and will be equal to the sum of the Present Values on the relevant Early Redemption Date of: (i) the Principal Amount of the Notes; and (ii) the remaining scheduled interest payments on the Notes up to and including the Optional Redemption Date (not including any Deferred Interest Payments or any interest amount accrued thereon or the portion of any scheduled interest payment in respect of which interest has already accrued prior to the relevant Early Redemption Date). In performing such calculation, it will be assumed that the Principal Amount of the Notes is due and payable on the Optional Redemption Date and that all interest payments that have not been paid prior to the relevant Early Redemption Date are due and payable in full.

28 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:29 – eprint6 – 4278 Section 02

TERMS AND CONDITIONS OF THE NOTES

In the event that the Issuer, the Guarantor and/or any Wholly Owned Subsidiary of the Guarantor has, individually or in aggregate, purchased (and not resold) or redeemed Notes equal to or in excess of 80 per cent. of the aggregate Principal Amount of the Notes issued on the Original Issue Date, the Issuer may redeem the remaining Notes (in whole but not in part):

(a) at any time prior to the Optional Redemption Date, at the Early Redemption Amount; or

(b) on, or on any Floating Interest Payment Date after, the Optional Redemption Date, at their Principal Amount plus any interest accrued and outstanding up to (but excluding) the Early Redemption Date and any Deferred Interest Payments (including any amount of interest accrued thereon in accordance with Condition 4.3), on the giving of not less than 30 and not more than 60 calendar days’ irrevocable notice of redemption to the Noteholders in accordance with Condition 13.1.

5.7 Optional Noteholder redemption upon a Change of Control Event

7.3 Additional Amounts, principal and interest

Any reference in these Conditions to any amounts in respect of the Notes will be deemed also to refer to any Additional Amounts which may be payable under this Condition 7 or under any undertakings given in addition to, or in substitution for, this Condition pursuant to the Trust Deed.

9. FURTHER ISSUES

The Issuer is at liberty from time to time without the consent of the Noteholders or Couponholders to create and issue further notes or bonds either (a) ranking pari passu in all respects (or in all respects save for the first payment of interest thereon) and so that the same will be consolidated and form a single series with the Notes or (b) upon such terms as to ranking, interest, conversion, redemption and otherwise as the Issuer may determine at the time of the issue. Any further notes which are to form a single series with the Notes will be constituted by a deed supplemental to the Trust Deed. Any further notes or bonds not forming a single series with the Notes will not be constituted by the Trust Deed.

SUMMARY OF PROVISIONS RELATING TO THE NOTES WHILE REPRESENTED BY THE GLOBAL NOTES

The following is a summary of the provisions to be contained in the Trust Deed to constitute the Notes and in the Global Notes which will apply to, and in some cases modify, the Terms and Conditions of the Notes while the Notes are represented by the Global Notes.

1. Exchange

The Notes will be represented initially by a Temporary Global Note in bearer form without Coupons or Talons which will be deposited outside the United States for a common depositary for Euroclear and Clearstream, Luxembourg on or about the Issue Date. The Temporary Global Note will be exchangeable in whole or in part (free of charge to the holder) for interests in a Permanent Global Note in bearer form without Coupons or Talons on or after a date which is 40 days after the Issue Date, upon certification as to non-U.S. beneficial ownership as required by U.S. Treasury regulations and as described in the Temporary Global Note.

The Permanent Global Note will be exchangeable in whole but not in part (free of charge to the holder) for definitive Notes only:

(a) upon the happening of any of the events defined in the Trust Deed as “Events of Default”;

(b) if the Issuer has been notified that both Euroclear and Clearstream, Luxembourg have been closed for business for a continuous period of 14 days (other than by reason of holiday, statutory or otherwise) or have announced an intention permanently to cease business or have in fact done so and no successor clearing system satisfactory to the Trustee is available; or

(c) if the Issuer has or will become subject to adverse tax consequences which would not be suffered were the Notes represented by the Permanent Global Note in definitive form and a certificate to such effect signed by one Authorised Signatory of the Issuer is given to the Trustee.

Thereupon (in the case of (a) and (b) above) the holder of the Permanent Global Note (acting on the instructions of one or more of the Accountholders (as defined below)) or the Trustee may give notice to the Issuer and (in the case of (c) above) the Issuer may give notice to the Trustee and the Noteholders, of its intention to exchange the Permanent Global Note for definitive Notes on or after the Exchange Date (as defined below).

On or after the Exchange Date the holder of the Permanent Global Note may or, in the case of (c) above, shall surrender the Permanent Global Note to or to the order of the Principal Paying Agent. In exchange for the Permanent Global Note the Issuer will deliver, or procure the delivery of, an equal aggregate principal amount of definitive Notes (having attached to them all Coupons in respect of interest which has not already been paid on the Permanent Global Note), security printed in accordance with any applicable legal and stock exchange requirements and in or substantially in the form set out in the Trust Deed. On exchange of the Permanent Global Note, the Issuer will procure that it is cancelled and, if the holder so requests, returned to the holder together with any relevant definitive Notes.

For these purposes, Exchange Date means a day specified in the notice requiring exchange falling not less than 60 days after that on which such notice is given and being a day on which banks are open for general business in the place in which the specified office of the Principal Paying Agent is located and, except in the case of exchange pursuant to (b) above, in the place in which the relevant clearing system is located.

2. Payments

On and after 7 December 2010, no payment will be made on a Temporary Global Note unless exchange for an interest in the Permanent Global Note is improperly withheld or refused. Payments

Each Accountholder must look solely to Euroclear or Clearstream, Luxembourg, as the case may be, for its share of each payment made to the bearer of the relevant Global Note.

5. Prescription

Claims against the Issuer and the Guarantor in respect of principal and interest on the Notes represented by a Global Note will be prescribed after 10 years (in the case of principal) and five years (in the case of interest) from the Relevant Date (as defined in Condition 7).

6. Cancellation

Cancellation of any Note represented by a Global Note and required by the Terms and Conditions of the Notes to be cancelled following its redemption or purchase will be effected by endorsement by or on behalf of the Principal Paying Agent of the reduction in the principal amount of the relevant Global Note on the relevant part of the schedule thereto.

Introduction

Santos Ltd (ACN 007 550 923) (the Guarantor or Santos) was incorporated with limited liability in A9.4.1.1

Adelaide, South Australia on 18 March 1954 and is registered under the Corporations Act 2001 of A9.4.1.2 Australia. Its principal and registered office is located at Ground Floor, Santos Centre, 60 Flinders Street, A9.4.1.3 Adelaide, South Australia 5000, Australia. The telephone number of its registered office is +61 8 8116 5000. A9.4.1.4

Santos has its ordinary shares listed on the Australian Securities Exchange (ASX). As at 8 September 2010, Santos had a market capitalisation of A$11.5 billion, making it one of Australia’s 30 largest listed companies by market capitalisation.

History and Development

Founded in 1954, Santos was originally South Australia Northern Territory and has been active in the energy business for more than 50 years. Santos acquired exploration leases covering over 325,000 square kilometres in South Australia and South West Queensland in 1954.

Santos made its first significant discovery of natural gas in the with the Gidgealpa 2 well in 1963. The Moomba 1 discovery in 1966 confirmed this region as a major petroleum province. As a result of these discoveries, Santos had a commercially viable quantity of gas and entered into Gas Sales Agreements with the South Australian Gas Company, the Electricity Trust of South Australia and the Australian Gas Light Company. Gas supplies commenced in 1969.

The 1980s saw Santos develop a major liquids business following the discovery of oil at Tirrawarra in the early 1970s. A liquids recovery plant was built at Moomba, along with a fractionation and load-out facility at .

By the 1990s Santos had become a major Australian operating enterprise with interests beyond the Cooper Basin in emerging areas such as the and Carnarvon Basin in Western Australia. A number of acquisitions in the 1990s provided Santos with additional opportunities onshore and offshore Australia, Indonesia and Papua New Guinea.

Since 2000, Santos has continued to build its business in South East Asia and Australia, while undertaking exploration activities and developing new projects to drive production and earnings growth.

More recently, Santos has focussed on expanding its LNG portfolio. The first of the LNG projects, the ConocoPhillips operated Darwin LNG project commenced first export of LNG in 2006. In 2009, the ExxonMobil operated PNG LNG project was formally approved for development. The project has signed binding long-term LNG sales agreements with four Asian buyers and first sales are expected in 2014. A final investment decision is expected in late 2010 for the Gladstone (GLNG) project. A fourth proposed LNG project, the Bonaparte floating LNG project, was announced in partnership with GDF SUEZ in 2009. An investment decision in respect of this project is expected in 2014.

Santos’ strategy is further outlined below under “Business Operations and Strategy“.

Business Overview A9.5.1.1

Santos’ business involves oil and gas exploration and production with interests in every major Australian petroleum province, and in Indonesia, Papua New Guinea (PNG), Vietnam, India, Bangladesh and Kyrgyz Republic.

Santos is the largest producer of gas sold in Australia, supplying 17 per cent. of the Australian domestic gas market in 2010. Santos supplies sales gas to all mainland Australian states and territories and ethane to Sydney. It sells oil and gas liquids to a number of domestic and international customers. As at 31 December

46 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:38 – eprint6 – 4278 Section 03

DESCRIPTION OF THE GUARANTOR

2009, Santos’ assets totalled A$11,361 million. Santos produced approximately 54.4 mmboe during 2009 and, as at 31 December 2009 had a substantial reserve base of approximately 1,440 mmboe on a 2P basis. Current production is approximately 600 mmscf/d of gas and approximately 40 kbbls/d of liquids.

As at 31 December 2009, Santos had 2,096 employees excluding contractors working across its operations and offices in Adelaide, , , Gladstone, Roma, Gunnedah and country offices in , Port Moresby, Hanoi, New Delhi, Bishkek and Dhaka.

Figure 1 below shows the location of Santos’ main operations and assets referred to in this document.

Figure 1: Guarantor’s main operations and assets referred to in this document

Business Operations and Strategy

Santos’ vision is to be a leading energy company in Australia and Asia. Santos’ strategy is to drive performance from its existing base business, deliver a suite of LNG projects and pursue focussed opportunities in Asia.

Australian Oil & Gas Operations.

Santos’ Australian base business comprises gas and oil production assets in all mainland states and the Northern Territory. Solid production combined with sanctioned projects and the potential of untapped reserves firmly places Santos in a position to serve the growing demand for natural gas and help Australia move towards a cleaner energy future.

Eastern Australian Gas

Santos’ business in Eastern Australia includes interests and joint ventures in the Cooper/Eromanga Basins in central Australia, Surat/Bowen CSG Basins in south-eastern Queensland and Otway/Gippsland Basins in offshore southern Australia. These basins are the primary source of gas supply into Victoria, NSW, ACT, South Australia and Queensland.

The Cooper Basin has been the heartland of Santos for more than four decades and still retains significant development potential. Santos believes gas demand in Australia’s eastern states will grow significantly as the region seeks cleaner energy through gas-fired power plants and a gas export channel is created through

47 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:38 – eprint6 – 4278 Section 03

DESCRIPTION OF THE GUARANTOR projects like Santos’ GLNG project. Established infrastructure and access to extensive pipeline networks positions the Cooper Basin to play a large role in meeting that demand. Santos is working to unlock its significant gas resources through enhanced recovery and infill drilling and by exploiting unconventional reservoirs.

Development work is also progressing on the ExxonMobil operated Kipper project in Victoria with first production expected in second half of 2011.

Santos took the next major step in its CSG strategy when it acquired significant additional acreage in the Gunnedah Basin of New South Wales and invested in leading local CSG Company Eastern Star Gas. Santos and Eastern Star’s total combined area of petroleum permits in the Gunnedah Basin in about 45,000 square kilometres.

Western Australian Oil and Gas

Santos is a leading gas supplier in Western Australia, having supplied gas there for over 20 years through interests in the Carnarvon Basin, offshore Western Australia, together with several small producing oil fields in the Timor Sea and Timor Gap. John Brookes is Santos’ major producing gas asset in the Carnarvon Basin and has been producing since 2005.

In addition to the producing assets, Santos has a portfolio of quality growth opportunities. Development of the Reindeer project offshore Western Australia was approved in 2008, with first gas scheduled for the fourth quarter of 2011. On 30 August 2010, Santos announced the development of the Halyard field, the latest Western Australian domestic gas project with production targeted to start in mid 2011.

LNG Projects:

Strong economic growth and primary energy demand in Asia alongside the desire for security of supply, a scarcity of hydrocarbon reserves in importing nations and the need for clean burning fuels has resulted in growing demand in the region for LNG. Santos has a strategic portfolio of four LNG projects in Asia at various stages of appraisal, development and operation to service this demand.

The Asia Pacific LNG market is characterised by binding offtake contracts between buyers and producers with a duration typically between 15 to 25 years and with pricing formulae agreed prior to production.

Darwin LNG – In operation since 2006

The Darwin LNG Project, operated by ConocoPhillips, is Santos’ first producing LNG asset. The project involves the export of gas from the Bayu-Undan fields, situated in 80 metres of water approximately 500 kilometres north-west of Darwin to a 3.6 mtpa LNG plant in Darwin. LNG production commenced in February 2006 with a contract to supply leading Asian utilities. Santos holds an 11.5 per cent. stake in the project. The Bayu-Undan fields in the Timor Gap produce approximately 1,100 MMscf/d of raw gas (gross) and approximately 103,000 bbl/d of liquids (gross).

PNG LNG – Approved in 2009

The PNG LNG Project, operated by ExxonMobil, was formally approved by Santos and project partners in December 2009 with financial close being achieved in March 2010. The PNG LNG project will develop the gas and condensate resources in the Hides, Angore and Juhu fields and the associated gas resources in the currently operating oil fields of Kutubu, Agogo, Gobe and Moran in the Southern Highlands and Western Provinces of Papua New Guinea. The gas will be transported by pipeline to a two train LNG facility with an initial capacity of 6.6 mtpa located northwest of Port Moresby on the coast of the Gulf of Papua. PNG LNG is the largest ever investment in PNG and is expected to double the country’s gross domestic product.

Santos has a 13.5 per cent. stake in the PNG LNG Project and a U.S.$2 billion share of the estimated total project capital cost which is funded as to approximately 70 per cent. by a completed project financing debt facility. The first LNG cargo is expected to be shipped in 2014 with plateau production of approximately 9 mmboe per annum net to Santos. Offtake agreements have been signed for all expected production, and will

DESCRIPTION OF THE GUARANTOR supply Sinopec, TEPCO, Osaka Gas and CPC Taiwan. Early works construction commenced prior to sanction and continues at the upstream and LNG plant locations and for supporting infrastructure. Further growth could arise from debottlenecking or from additional resources giving rise to a potential third LNG train.

GLNG – Expected approval in 2010 A9.4.1.5

Santos’ proposed GLNG Project involves the production of LNG using CSG sourced from the GLNG gas fields in the Bowen and Surat Basins in Queensland. The Fairview Field in the Bowen Basin has been producing gas since 1995.

GLNG is making significant progress towards a final investment decision in 2010 and Santos will provide updated project information to the relevant listing authorities prior to or at final investment decision. There is no certainty that a final investment decision will be reached for GLNG. The design contemplates a two- train development with a capacity of 7.2 mtpa of LNG.

In May 2010, GLNG became Australia’s first major CSG to LNG project to receive environmental approval from the Queensland Government. On 22 October 2010, the Project received environmental approval from the Federal Government. The approval is conditional upon GLNG maintaining certain environmental standards in constructing and maintaining the Project. Engineering design works for the project are nearing completion.

In September 2010, Santos announced that it had entered into an agreement to sell 15 per cent. equity in GLNG to Total E&P Australia. Additionally, Santos announced the sale of 1 mtpa of LNG from Train 1 and 0.5 mtpa of LNG from Train 2 to Total E&P Australia and the further sale of LNG to PETRONAS along with a re-configuration of the LNG volumes previously sold to PETRONAS such that PETRONAS’ offtake from GLNG would be 2.33 mtpa from Train 1 and 1.17 mtpa from Train 2. In parallel, PETRONAS also entered into an agreement to sell a 5% interest in GLNG to Total E&P Australia.

Upon completion of the Santos and PETRONAS sale transactions, the ownership structure of GLNG will be: Santos 45 per cent.; PETRONAS 35 per cent.; and Total E&P Australia 20 per cent. Australian Foreign Investment Review Board approval for the Total acquisition has been granted and it is anticipated that the sale transaction will be completed in the near term.

Santos and GLNG remain in detailed ongoing discussions with a number of Asian parties in relation to further potential LNG sales and equity in the project. These parties include KOGAS, the world’s largest LNG buyer.

Bonaparte LNG – Expected approval in 2014

Santos has partnered with France’s GDF SUEZ, to develop Bonaparte LNG, a proposed 2 mtpa floating LNG project, located in the Timor Sea off the northern coast of Australia.

As part of the partnership, GDF SUEZ has bought 60 per cent. of the Petrel, Tern and Frigate gas fields from Santos for up to U.S.$370 million, and will carry all of Santos’ share of the costs until a final investment decision, expected in 2014. The resource is approximately 2.1 trillion cubic feet (TCF) gross.

Asia

Santos has built a strong and reliable production business in Indonesia and is further developing its Asian business through development projects and exploration investment in Indonesia, Vietnam, India, Bangladesh and Kyrgyz Republic.

PNG

In addition to its interest in the PNG LNG development, Santos has interests in PNG that produced 0.1 mmboe net to Santos in 2009.

49 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:38 – eprint6 – 4278 Section 03

DESCRIPTION OF THE GUARANTOR

Indonesia

Santos first acquired interests in Indonesia in 1993. Santos holds a 67.5 per cent. operating interest in the Madura Offshore Production Sharing Contract (PSC), located in offshore east Java which contains the Maleo field. Production commenced from the Maleo gas project in September 2006, which now has gross gas production of approximately 110 mmscf/d.

Santos also holds a 45 per cent. operating interest in the Sampang PSC, also located in offshore East Java. The Oyong field was discovered in 2001 and oil production commenced in 2007. The existing offshore facilities have been modified with the construction of a 60 kilometre pipeline to a new onshore gas processing facility and first gas production commenced in October 2009.

Santos is expected to approve the Wortel Project in 2010, which is a tie back to Oyong, with first gas forecasted in second half of 2011.

Vietnam

In 2006, Santos entered Vietnam via a farm-in to the Nam Con Son and Hong Song Basins. The Chim Sao field in the Nam Con Son basin was discovered in the same year and approved for development in 2009. The development of this field is proceeding on track with first oil expected in the second half of 2011 with a net plateau production of approximately 8,000 bbl/d.

India and Bangladesh

During May 2007, Santos was awarded a 100 per cent. working interest and operatorship of blocks covering approximately 16,500 square kilometres in the Bengal Basin, in the northern Bay of Bengal, offshore India. An extensive 3D seismic program began in 2008 and is largely complete. Santos’ ability to conduct operations (including the completion of the 3D seismic program) in certain areas within the blocks has, however, been directly affected by circumstances arising in connection with the maritime boundary dispute between India and Bangladesh. Bangladesh commenced arbitration proceedings (under the United Nations Convention on the Law of the Sea) against India with respect to its maritime boundary claims in October 2009. The award of the tribunal will be binding on each of the States and the arbitration proceedings are expected to take approximately 3 to 5 years to finish. This timing is not certain, however, and it is also possible that negotiations between India and Bangladesh may result in a binding settlement being reached with respect to the dispute prior to the conclusion of the arbitration proceedings.

Santos acquired assets in Bangladesh in October 2007 from Cairn Energy PLC (Cairn). Santos acquired a 37.5 per cent. non-operating interest in the producing Sangu Development Area and a 37.5 per cent. Non operating interest in the Block 16 exploration acreage.

Kyrgyz Republic

Santos has established a substantial acreage position in the Fergana Basin in the south of the Kyrgyz Republic. Santos holds interests in six prospecting licences covering approximately 2,700 square kilometres in the proven oil and gas province. 2D seismic work has been completed and shallow drilling occurred in 2009. Deeper drilling is planned for 2011 to further evaluate the potential of these assets.

The Fergana Basin covers an area of 63,000 square kilometres and has been producing hydrocarbons since the early 1900s.

Santos has in place an evaluation and reporting process that is in line with international industry practice and is in general conformity with reserves definitions and resource classification systems published by the Society of Petroleum Engineers, World Petroleum Congress and the American Association of Petroleum Geologists.

Santos has the largest Australian exploration portfolio by area (133,800 square kilometres) and a substantial Asian asset base. At the end of 2009, Santos had 2P reserves of 1,440 mmboe. Over the past five years Santos has more than doubled 2P reserves despite producing almost 300 million barrels of oil equivalent in this period. At the current rate of production, Santos has an average reserve life of approximately 26 years based upon 2P reserves. Santos has added reserves and resources at a compound annual growth rate of 14% from 2004 to 2009.

Santos now has almost half of its reserves targeted at the higher margin LNG business, and about a third of those are conventional reserves at PNG LNG and Darwin LNG.

Details of Santos’ 2009 Reserves statistics are set out in Table 2 below.

Applicable Regulatory Issues

Australia

Taxation

Excise and royalty on the production of hydrocarbons is levied via a regime of excise, royalties and petroleum resource rent tax.

Onshore, federal excise is levied on the net volume of oil and condensate removed (after removal of water and gas) from a producing field in excess of the first 30 mmbbL of production, which is excise free. Thereafter, excise is charged on an annual sliding scale of marginal rates for oil ranging from nil (up to 3.15 mmbbL) to 30 per cent. (above 5.03 mmbbL). Lesser rates of excise apply to condensate. State royalty is payable as a percentage of the wellhead value of all production (gross value of petroleum less approved post wellhead costs). The royalty rate currently payable by the Issuer in South Australia, Queensland and the Northern Territory is 10 per cent.

In relation to its offshore operations, excise and royalty of 10 per cent. apply to production licences on Thevenard Island. Barrow Island is covered by the Resource Rent Royalty (RRR) tax regime which is unique to the island and replaced the well-head royalty and excise regime described above. RRR is charged at a rate of 40 per cent. of the net cashflow from annual production (the accumulated value of sales less eligible deductions).

In addition, the Petroleum Resource Rent Tax (PRRT) applies in all Commonwealth waters, other than the North West Shelf permits. PRRT is charged at a rate of 40 per cent. of the taxable profit of a project. For further details, see “Risk Factors - Mineral Resources Rent Tax and other Australian taxes”.

Exploration and Production Licences

Petroleum resources within Australia are the property of the Crown and rights to explore and produce are conferred by statutory titles granted by legislation of the relevant State or Territory, the most significant of which are exploration and production leases or licences.

The ownership and operation of gas transportation pipelines is regulated by State, Territory and Commonwealth legislation. Petroleum operations in Australian territorial waters are subject to the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA) in respect of operations in Commonwealth waters and the various State and Territory Acts in respect of operations in areas adjacent to the respective State or Territory. These legislations regulate exploration and development operations including the grant of key titles, such as Exploration Permits, Retention Leases, Production Licenses and Pipeline Licences.

Exploration licences are usually subject to the condition that a prescribed minimum work programme be carried out, and to progressive acreage relinquishment after the elapse of prescribed periods. Production licences generally enure for the full productive life of all fields, including those developed after the production licence is granted.

Joint Petroleum Development Area

The Joint Petroleum Development Area (formerly known as the Timor Gap Zone of Co-operation) is subject to an international agreement between Australia and the Timor-Leste.

Under the Bayu-Undan PSCs, Santos and its contractors are entitled to a share of first tranche petroleum, which is a 10 per cent. portion of gross revenue “distributed” prior to cost recovery, equal to 60 per cent. of revenue from LPG and gas and 50 per cent. of revenue from condensate, an investment credit equal to 127 per cent. of eligible exploration and capital costs, recovery of costs (operating costs, intangibles

DESCRIPTION OF THE GUARANTOR expensed and depreciation of tangibles at 20 per cent. straight line) and a share of remaining “profit oil or gas”. Profit oil is split on a sliding scale from 50 per cent. of the first 50,000 barrels per day to 30 per cent. over 150,000 barrels per day, contractors’ share. Profit gas and LPG is 60 per cent. and profit condensate is 50 per cent. contractors’ share. In addition, income tax and additional profits tax is applicable in Timor Leste on 90 per cent. of income and income tax is applicable in Australia on 10 per cent. of income.

Indonesia

The development of Indonesia’s natural resources is based on the philosophy enshrined in Article 33 of the Constitution that all natural resources fall under the jurisdiction of the State. Upon being granted a PSC, the contractor is committed to a minimum level of exploration activity. If commercial hydrocarbons are found, the contractor must apply for commerciality of the block to the government and will be required to submit a plan of development.

Post tax profit share for oil is typically 85:15 in favour of the State, and for gas 70:30 or 65:35 in favour of the State. At tax rates of 44 per cent. to 48 per cent., these splits generate a pre tax profit share to the contractor of between 26.8 per cent. and 28.8 per cent. for oil and between 53.6 per cent. and 62.5 per cent. for gas.

All PSCs in Indonesia are subject to a domestic market obligation (DMO) for oil. This obligation occurs five years after first oil production for new fields and the contractor is required to supply a percentage of oil to the domestic market at a reduced price. No DMO is applicable on gas production. The price at which the domestic crude is sold depends on the date of signing the PSC and is typically between 10 per cent. and 25 per cent. of the export price.

Vietnam

Santos is a party to a number of PSCs entered into with Vietnam Oil and Gas Corporation (PetroVietnam), the State owned national oil company with authority under Article 14 of the Petroleum Law (1993) to enter into PSCs.

Contractors are subject to income tax of 32 per cent. and export duty of 4 per cent. on oil exports. The contractors are also required to make bonus payments to PetroVietnam upon commercial discovery and on reaching various production rates.

TAXATION

Australian Taxation

The following is a general summary of the taxation treatment under the Income Tax Assessment Act 1936 and the Income Tax Assessment Act 1997 (together, the “Tax Act”) and any relevant regulations, rulings or judicial or administrative pronouncements, at the date of this Prospectus, of payments of interest and certain other amounts on the Notes and certain other matters.

Tax considerations which may arise for investors who are in the business of trading or dealing in securities, or otherwise hold Notes on revenue account have not been considered in this tax summary.

This summary is not exhaustive and is not intended to be, nor should it be construed as, legal or tax advice to any particular investor. Prospective Noteholders should consult their professional advisers on the tax implications of an investment in the Notes in their particular circumstances.

1. Interest withholding tax

Absent the exemptions discussed below, payments of interest on the Notes would be within the scope of Australia’s rules on interest withholding tax. Division 11A of Part III of the Tax Act provides that a payment of interest by an Australian resident, not acting through a permanent establishment outside Australia, to a non-resident, not acting through a permanent establishment in Australia; or to an Australian resident acting through a permanent establishment outside Australia, is ordinarily subject to withholding tax at the rate of 10%.

For the purposes of Division 11A, subsection 128(1AB) provides that interest includes amounts in the nature of interest. A premium on redemption of a security would generally be treated as an amount in the nature of interest. A payment by the Guarantor to a Noteholder in respect of accrued interest on a Note may also be interest, or in the nature of interest, for these purposes.

A payment in consideration of the transfer of certain securities can be deemed to be interest: • under section 128AA where the transfer price of a ‘qualifying security’ exceeds the issue price; or • where the security is disposed of to an Australian resident prior to the payment of interest with the sole or dominant purpose of avoiding withholding tax on that interest (a ‘washing arrangement’).

Section 128F exemption

Under section 128F of the Tax Act, an exemption from Australian interest withholding tax applies provided all prescribed conditions are met. The exemption under section 128F extends to interest under subsection 128(1AB) paid by an issuer and, where applicable, deemed interest on transfer of a qualifying security under section 128AA.

The relevant conditions to be satisfied in respect of the Notes are: • the Issuer is a resident of Australia when it issues the Notes and when interest is paid in respect of the Notes; • interest is not paid to an associate of the Issuer of the kind described below; • the Notes are debentures; and • the Notes are offered for issue in a manner which satisfies the public offer test. In broad terms, an issue of the Notes will satisfy the public offer test where there are: • offers to 10 or more unrelated financiers or securities dealers;

57 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:38 – eprint6 – 4278 Section 04

TAXATION

• offers to 100 or more persons that are reasonable to regard as having acquired similar instruments in the past, or as being likely to be interested in acquired the Notes; • offers of Notes as a result of them having been accepted for listing on a stock exchange; • offers via publicly available information sources; or • offers to a dealer, manager or underwriter who offers to sell those Notes within 30 days by one of the preceding methods.

The public offer test will not be satisfied if, at the time of issue, the Issuer knew or had reasonable grounds to suspect that the Notes were being or would later be acquired directly or indirectly by an associate of the Issuer (within the meaning of subsection 128F(9)) that is: • a resident of Australia that would acquire the Note through a permanent establishment outside Australia, or a non-resident that would not acquire the Note through a permanent establishment in Australia; and • is not acting in the capacity of a dealer, manager or underwriter in relation to the placement of the relevant Notes, or a clearing house, custodian, funds manager or responsible entity of a registered managed investment scheme.

Even if the public offer is satisfied, a payment of interest will not be exempt from withholding tax if it is in fact paid to an associate of the Issuer within the meaning of subsection 128F(9) that is: • a resident of Australia that would acquire the Note through a permanent establishment outside Australia, or a non-resident that would not acquire the Note through a permanent establishment in Australia; and • is not acting in the capacity of a clearing house, paying agent, custodian, funds manager or responsible entity of a registered managed investment scheme.

The Commissioner of Taxation accepts that where payments by a guarantor would be interest for withholding tax purposes, the exemption in section 128F will be available in respect of such payments (provided the requirements of section 128F are satisfied).

Although the section 128F interest withholding tax exemption does not apply to deemed interest under a ‘washing arrangement’ where interest in respect of the Notes is otherwise exempt from interest withholding tax, a Noteholder could not be taken to have a purpose of avoiding withholding tax by transfer of the Notes and so these provisions should not apply.

The taxation of financial arrangements (TOFA) provisions in Division 230 of the Tax Act do not affect the availability of the section 128F interest withholding tax exemption.

Compliance with the section 128F exemption

The Issuer intends to issue the Notes in a manner that will satisfy the conditions for the application of the interest withholding tax exemption in section 128F. In particular, and pursuant to an agreement between the Issuer and the Managers, it is expected that Notes will not be issued or sold to an associate of the Issuer in a manner that would cause the failure of the public offer test in the section 128F exemption.

Where section 128F applies, payments of interest (and principal) on the Notes will not be subject to Australian interest withholding tax, where the Noteholder is a non-resident and does not hold the Notes in the course of carrying on a business through a permanent establishment in Australia.

Other exemptions

In the event that the section 128F exemption did not apply to a payment of interest in respect of the Notes, a payment to a person outside Australia may nonetheless be exempt from interest withholding tax if:

58 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:38 – eprint6 – 4278 Section 04

TAXATION

• the Noteholder is a pension or superannuation fund for non-residents that is exempt from income tax in its country of residence; • the Noteholder is entitled to the benefit of the sovereign immunity doctrine; or • the Noteholder is a resident of a country with which Australian has concluded a double tax treaty and is entitled to the benefits of an exemption under that treaty.

Payment of additional amounts

As set out in more detail in the Terms and Conditions, if the Issuer or the Guarantor is at any time required by law to deduct or withhold an amount in respect of any withholding taxes imposed or levied by the Commonwealth of Australia in respect of the Notes, the Issuer or Guarantor must, subject to certain exceptions, pay such additional amounts as may be necessary in order to ensure that the net amounts received by the holders of those Notes after such deduction or withholding are equal to the respective amounts which would have been received had no such deduction or withholding been required.

A payment of an additional amount in these circumstances is not itself interest, or in the nature of interest, and so should not be subject to additional withholding tax.

If the Issuer or Guarantor is compelled by law in relation to any Notes to deduct or withhold an amount in respect of any withholding taxes, the Issuer will have the option to redeem those Notes in accordance with the Terms and Conditions.

2. Income Tax

Non-residents

Where a Noteholder is a non-resident, and the Noteholder does not hold the Notes through a permanent establishment in Australia, interest paid in respect of the Notes should not be included in the assessable income of the Noteholder.

A gain arising to a non-resident Noteholder from disposal of Notes should only be subject to Australian tax, and a loss should only be deductible, if: • the non-resident Noteholder is resident of a country with which Australia has concluded a comprehensive double tax treaty and the Notes are held through a permanent establishment through which the Noteholder is doing business in Australia; or • the non-resident Noteholder is not resident of a country with which Australia has concluded a comprehensive double tax treaty and the gain has an Australian source. Where a non-resident Noteholder makes a gain from a disposal of a Note to another non-resident, and the relevant negotiations are undertaken and the transaction is documented outside of Australia, the gain would not ordinarily an have an Australian source.

Australian residents

Interest derived by an Australian resident Noteholder in respect of the Notes, and any gains upon disposal or redemption, should be included in their assessable income, subject to any specific exemption applicable to that Noteholder.

The manner and timing of inclusion of such amounts in assessable income will depend upon the specific tax rules applying to the Noteholder, including whether and how the TOFA rules in Division 230 of the Tax Act apply to the Noteholder. Where the TOFA rules do not apply, a Noteholder will need to consider the application of the rules dealing with ‘traditional securities’ and the foreign exchange tax rules in Division 775 and Subdivision 960-C of the Tax Act.

59 Level: 5 – From: 5 – Monday, October 25, 2010 – 09:38 – eprint6 – 4278 Section 04

TAXATION

3. Other Australian tax matters

Debt interests

The Notes should be ‘debt interests’, rather than ‘equity interests’, for the purposes of Australian debt/equity tax rules. Accordingly, interest paid on the Notes should not be treated as dividends for the purposes of Australia’s dividend imputation (franking) system and dividend withholding tax rules.

Stamp duty

Subject to the Notes being ‘debt interests’ as described above, no ad valorem stamp, issue, registration or similar taxes are payable in Australia on the issue or transfer of any Notes.

Goods and services tax (GST)

Neither the issue of the Notes, the payment of interest in respect of the Notes, nor the redemption of the Notes will give rise to a liability for GST in Australia. Dealings in respect of the Notes will comprise either an input taxed financial supply or (in the case of an offshore Noteholder) a GST-free supply.

Bearer debentures withholding tax

Where a company pays interest on a bearer debenture to an Australian resident, or to a non-resident holder that holds the bearer debenture through a permanent establishment in Australia, and the issuing company does not give the Commissioner of Taxation the name and address of the holder, then the issuing company is liable to pay tax on that interest at the rate of 45%, pursuant to section 126 of the Tax Act to non- residents. No such tax is payable where the section 128F exemption applies to payments of interest. If section 126 applies to a Note, the Issuer is authorized by subsection 126(2) of the Tax Act to deduct the amount of this tax from the interest otherwise payable to the Noteholder.

For these purposes, the Issuer intends to treat the operator of a clearing system that holds the physical Notes as being the holder of the Notes for these purposes.

TFN Withholding tax

A Noteholder that does not provide their tax file number, Australian Business Number or exemption category may have an amount of tax deducted from any interest in respect of the Notes equal to the top marginal tax rate for individuals plus the Medicare levy (currently 46.5%). A Noteholder that is a non- resident and does not hold the Notes through a permanent establishment in Australia is exempt from quoting a tax file number.

Supply withholding tax

Payments in respect of the Notes can be made free and clear of the “supply withholding tax” imposed under section 12-190 of Schedule 1 to the Taxation Administration Act 1953 of Australia (Taxation Administration Act).

Additional withholdings from certain payments to non-residents

Section 12-315 of Schedule 1 to the Taxation Administration Act gives the Governor-General power to make regulations requiring withholding from certain payments to non-residents of Australia. However, section 12 315 expressly provides that the regulations will not apply to interest and other payments which are already subject to Division 11A of Part III of the Tax Act or specifically exempt from those rules. Further, regulations may only be made if the responsible Minister is satisfied the specified payments are of a kind that could be reasonably related to the assessable income of foreign residents. The existing regulations made pursuant to section 12-315 are not relevant to any payments in respect of the Notes and it is not anticipated that any future regulations would apply in respect of such payments.

TAXATION

Garnishee notices

The Commissioner of Taxation may issue a notice requiring any person who owes, or who may later owe, money to a taxpayer who has a tax-related liability, to pay to him the money owed to the taxpayer. If the Issuer or the Guarantor is served with such a notice in respect of a Noteholder, then the Issuer or the Guarantor (as the case may be) will comply with that notice.

Death duties

No Notes will be subject to death, estate or succession duties imposed by Australia, or by any political subdivision or authority therein having power to tax, if held at the time of death.

SUBSCRIPTION AND SALE

UBS Limited and Deutsche Bank AG, London Branch (the Managers) have, pursuant to a Subscription Agreement (the Subscription Agreement) dated 26 October 2010, jointly and severally agreed to subscribe or procure subscribers for the Notes at the issue price of 101.00 per cent. of the principal amount of the Notes plus accrued interest from, and including, the Original Issue Date to, but excluding, the Issue Date. The Issuer will pay to the Managers a combined selling, management and underwriting commission. The Issuer will also reimburse the Managers in respect of certain of their expenses, and has agreed to indemnify the Managers against certain liabilities, incurred in connection with the issue of the Notes. The Subscription Agreement may be terminated in certain circumstances prior to payment of the Issuer.

United States

The Notes and the Guarantee have not been and will not be registered under the Securities Act and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in certain transactions exempt from the registration requirements of the Securities Act.

The Notes are subject to U.S. tax law requirements and may not be offered, sold or delivered within the United States or its possessions or to a United States person, except in certain transactions permitted by U.S. tax regulations. Terms used in this paragraph have the meanings given to them by the U.S. Internal Revenue Code of 1986 and regulations thereunder.

Each Manager has agreed that, except as permitted by the Subscription Agreement, it will not offer, sell or deliver the Notes and the Guarantee (a) as part of their distribution at any time or (b) otherwise until 40 days after the later of the commencement of the offering and the Issue Date within the United States or to, or for the account or benefit of, U.S. persons and that it will have sent to each dealer to which it sells any Notes and the Guarantee during the distribution compliance period a confirmation or other notice setting forth the restrictions on offers and sales of the Notes and the Guarantee within the United States or to, or for the account or benefit of, U.S. persons. Terms used in this paragraph have the meanings given to them by Regulation S under the Securities Act.

In addition, until 40 days after the commencement of the offering, an offer or sale of Notes or the Guarantee within the United States by any dealer that is not participating in the offering may violate the registration requirements of the Securities Act.

United Kingdom

Each Manager has represented and agreed that:

(a) it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) received by it in connection with the issue or sale of any Notes in circumstances in which Section 21(1) of the FSMA does not apply to the Issuer or the Guarantor; and

(b) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to any Notes in, from or otherwise involving the United Kingdom.

Commonwealth of Australia

No prospectus or other disclosure document (as defined in the Corporations Act of Australia 2001 (Corporations Act)) in relation to the Notes has been or will be lodged with the Australian Securities & Investments Commission (ASIC). Each Manager has represented and agreed that it:

(a) has not (directly or indirectly) offered, and will not offer for issue or sale and has not invited, and will not invite, applications for issue, or offers to purchase, the Notes (including interests or rights in Notes held in Euroclear or Clearstream, Luxembourg or any other clearing system) in, to or from Australia (including an offer or invitation which is received by a person in Australia); and

AUSTRALIAN ACCOUNTING STANDARDS AND FINANCIAL A9.11.1 STATEMENTS

The Guarantor and the Issuer prepare financial statements in accordance with Australian Accounting Standards which are compliant with International Financial Reporting Standards as issued by the International Accounting Standards Board, with the exception of certain disclosure exemptions applicable to the Issuer which are detailed in Note 1(a) of the financial statements of the Issuer incorporated by reference in the Prospectus. Under Australian law, the Issuer has been classified as a “non-reporting entity” which must prepare its financial statements in accordance with Australian Accounting Standards, and therefore IFRS standards generally, but is exempted from making all of the detailed disclosures required by Australian Accounting Standards and IFRS in the notes to its financial statements. There are no differences between the Issuer’s reported results, financial position or cash flows prepared under Australian Accounting Standards and the results, financial position or cash flows the Issuer would have reported under IFRS because the measurement and recognition criteria of IFRS and Australian Accounting Standards are consistent. Following the issue of the Original Notes, the Issuer is no longer considered a “non-reporting entity” and is required to prepare general purpose financial statements incorporating all of the presently exempted financial statement note disclosure requirements.

The Guarantor and the Issuer prepare annual financial statements as at 31 December each year which are subject to audit by the Group’s auditors. The Guarantor also prepares six-month consolidated financial statements as at 30 June each year which are subject to review by the Group’s auditors.
