The Directors of AES Drax Holdings Limited c/o Kempson House Camomile Street London EC3A 7AN 21 August 2003 Dear Sirs DRAX - BHP BILLITON'S OFFER We are pleased to submit this offer by BHP Billiton plc ("BHP BILLITON") to provide support to facilitate the restructuring of the senior secured debt and other contractual arrangements of AES Drax Holdings Ltd (the "Company") and certain of its affiliates, including AES Drax Power Limited ("DRAX POWER") (the "BHP BILLITON Offer"). While the BHP Billiton Offer is made by BHP Billiton solely on the terms and conditions set out in this offer letter (the "BHP BILLITON OFFER LETTER") and its schedules (the "SCHEDULES"), the BHP Billiton Offer to a large extent follows the restructuring proposals as laid out in (i) the 30 June 2003 Form 6K filing to the US Securities and Exchange Commission (SEC File #333-13096) ("30 JUNE 6K") and (ii) the 14 August 2003 Form 6K filing to the US Securities and Exchange commission (SEC File #333-13096) ("14 AUGUST 6K") with a view to facilitating the completion of the restructuring of the secured debt of the AES Drax Companies and the entering into of the commercial agreements as set out in BHP Billiton Offer Letter (the "RESTRUCTURING"). The BHP Billiton Offer includes a number of key commercial and economic terms, which we believe substantially enhance the terms of the Restructuring and as such maximise the ultimate recoveries for the Senior Banks, the Senior Bondholders and the Hedging Banks, whether or not they intend to exercise the Cash-Out Option. We strongly believe that an integrated financial and commercial partnership between BHP Billiton and/or certain of its affiliates and the Company and its relevant affiliates under which BHP Billiton (or an affiliate) provides coal supply and energy trading services, together with O&M expertise from Eskom Enterprises (Pty) Ltd, a wholly owned subsidiary of Eskom Holdings (Pty) Ltd ("ESKOM"), adds significant value to the restructuring by increasing the certainty of operating cashflows and mitigating key commodity and operational risks. BHP Billiton is the world's largest diversified resources company with a market capitalisation of (pound)26.2 billion and a strong balance sheet and credit rating. We are a major provider of both coal and natural gas to the power generation industry. In particular, BHP Billiton Energy Coal is the world's largest producer and marketer of sea-borne thermal coal. Our focus is on providing competitive energy solutions for our world-wide portfolio of power generation customers. The business is structured around a portfolio of world-class producing assets, which provide a unique multi-sourcing capability to service the major power markets of Europe and the United Kingdom in particular. We have a proven track record and are a respected partner in joint ventures worldwide. Eskom, the South African electricity utility company, operates 42,000 MW of power generation capacity, of which 37,000 MW comprises large coal-fired plants including seven power stations with capacity in 1 excess of 3,000 MW. Eskom is a key business partner of BHP Billiton in South Africa and the two companies have a strong relationship extending over many years. We recognise the dual needs of the Senior Creditors to meet the short-term financial objectives of the Restructuring, while at the same time ensuring the long-term viability of the Company. We believe that the BHP Billiton Offer demonstrates a clear differentiation in value from the other proposals received by the Company and provides for increased long-term security for the Senior Creditors through a unique and distinctive set of capabilities and service offerings. The main points of the BHP Billiton Offer are as follows: o BHP Billiton will provide substantial funding for the Cash-Out Option with a significant premium to other offers based on a similar financial structure. o BHP Billiton offers to provide a unique suite of value-added fuel, finance, O&M and commodity services that creates substantial value for the Principal Drax Assets and does not diminish commercial control or reduce flexibility for Senior Creditors. o The BHP Billiton Offer is an integrated solution that provides clarity of outcome through the creation of a stable, on-going and viable entity with improved credit profile, lower cost base and reduced risk profile. o A partnership with BHP Billiton will bring to the AES Drax Companies all the credentials and capabilities of a world leading energy company with an excellent credit rating. This partnership will help the AES Drax Companies address the key challenges they face in their transition to consuming imported coal. o BHP Billiton is willing to arrange, at the Company's option, a (pound)100,000,000 Trading Guarantee Facility to facilitate Drax Power's ability to trade electricity. o BHP Billiton's Offer is not subject to or contingent on third party financing and does not result in any underwriting or other fees and charges being paid to BHP Billiton. BHP Billiton is willing to discuss placing amounts in escrow once a timetable for the overall Restructuring is agreed between BHP Billiton and the Senior Creditors. o BHP Billiton is able to work closely with the directors and Senior Creditors to meet the timetable of the Restructuring and address governance issues through discussion and negotiation. The summary terms of the BHP Billiton Offer are as follows1: 1 BHP Billiton offers to increase the price for creditors who decide to tender their A-2 Debt, C Debt (which will be renamed under the BHP Billiton Offer "A-3 DEBT"), and Equity (the "CASH-OUT OPTION") to 70 per cent. of the A-2 principal amount, a substantial improvement to the prices proposed by The AES Corporation ("AES"), International Power plc ("IP") and Goldman Sachs International ("GS"). BHP Billiton would also pay 1% for the A-3 Debt. BHP Billiton (or an affiliate) will provide up to (pound)95,000,000 of cash to support the funding of the Cash-Out Option ("BHP BILLITON FUNDS"). If demand for the Cash-Out Option is so strong that additional funds are required, BHP Billiton reserves the right to increase its participation and, if necessary, will endeavour to obtain additional funding from third parties wishing to purchase the A-2 Debt. To the extent that such - ------------- 1 Additional detailed information is contained in the various Schedules attached to the BHP Billiton Offer Letter. Any capitalised term used but not otherwise defined in this BHP Billiton Offer Letter shall have the meaning given to it in Schedule 4 of this Offer Letter. To the extent there is any inconsistency between the BHP Billiton Offer Letter and the Schedules, the terms of the BHP Billiton Offer Letter will prevail. 2 funding is not available, there would be a "scale back" as provided under section 1.3.3 of Schedule 4 of this BHP Billiton Offer Letter. To the extent that the Cash-Out Option is funded by BHP Billiton Funds, BHP Billiton will purchase pro-rata holdings of the A-2 Debt and the A-3 Debt and will have the option to become the owner of the Equity corresponding to the amount of the A-3 Debt purchased by BHP Billiton. 2 BHP Billiton will leave it to the option of the Company and the Senior Creditors whether they elect to use (pound)30,000,000 (the minimum required by BHP Billiton) of cash currently held by the Company or such higher amounts as may be deemed by the directors of the Company to be available in order to fund the Cash-Out Option. To the extent that the Company and the Senior Creditors elect to use more than (pound)30,000,000 of Project Funds, the Cash-Out Option will be funded as follows: first, (pound)30,000,000 of Project Funds will be used; second, the amount of incremental Project Funds in excess of the (pound)30,000,000 that the Company and the Senior Creditors elect to use, and finally any additional amounts that are required will be funded from BHP Billiton Funds until BHP Billiton Funds are exhausted. 3 The BHP Billiton Offer increases the margin on the A-2 Debt to 400bps. In addition, the terms and ranking of the B Debt and the A-3 Debt would be as follows: the A-3 Debt will rank behind the A-2 Debt but ahead of the B Debt, both in the Cash Flow Waterfall and with respect to its security over the Principal Drax Assets. The A-3 Debt will have fourth ranking security over the Principal Drax Assets and will accrue interest at a rate of Libor + 500bp, with the potential of having interest deferred if no funds are available under the Cash Flow Waterfall (similar to the A-2 Debt). The B Debt will accrue interest at the rate of Libor + 200bp with the potential of having interest deferred if no funds are available under the Cash Flow Waterfall (similar to the A-2 Debt and the A-3 Debt). The B Debt will have first ranking security over the claims against TXU Europe Energy Trading Limited and TXU Europe Group plc (the "TXU Claim"), as well as a fifth ranking security over the Principal Drax Assets. The holders of the B Debt however will not have any voting rights with respect to the release of their security over the Principal Drax Assets, the sale of the Company, or a recapitalisation of the balance sheet. The B Debt holders may (by a 75 per cent. majority) agree to compromise the TXU Claim or vote the interest of the AES Drax Companies in any insolvency in respect of the TXU Claim. The A-3 Debt holders shall have the first right of refusal to purchase all (or materially all) but not part of the Drax Principal Assets if the A-1 Debt holders and/or A-2 Debt holders have resolved to sell such assets. 4 It is a condition of BHP Billiton's Offer that BHP Billiton (or an affiliate) will enter an agreement for the supply of coal to the Drax power station for 15 years from January 2004. The agreement would be structured to ensure supply security for Drax Power, allowing it to retain maximum operational flexibility and mitigate risks in relation to Drax Power's most significant cost item. It would allow significant volume flexibility on coal supply which will be essential in ensuring an efficient transition to sourcing more imported coal as local domestic coal production declines. Subject to existing coal supply contracts, BHP Billiton (or an affiliate) would supply 100% of Drax's coal requirements on an exclusive basis from January 2006 to December 2010, and would thereafter continue to supply 80% of the plant's total requirements to 2018. The remaining 20% during this period would be subject to a competitive tender in which BHP Billiton (or an affiliate) would be entitled to participate. The price for coal supplied by BHP Billiton (or its affiliate) would be based on a competitive market index with a fixed-price adjustment for UK-based logistics. BHP Billiton (or an affiliate) will also assume management of the entire logistics chain of its coal supply to Drax Power, including sea freight, port facilities and rail transportation. BHP Billiton's position as a major coal supplier would enable it to minimise stockpile requirements and thereby reduce working capital requirements for 3 Drax Power, manage the blending of coals to ensure plant specifications are met and cover risks associated with delivery to the plant. (Further details are set out in Schedule 5). 5 Drax Power will require substantial credit support to continue its electricity trading activities following the Restructuring. If Drax Power is no longer required to provide cash collateral as credit support this will enhance the liquidity of the Drax power station and provide cash for other purposes, including working capital and funding the Cash-Out Option. BHP Billiton is willing to arrange, subject to agreement of satisfactory commercial terms by 30 September 2003, a (pound)100,000,000 Trading Guarantee Facility to facilitate Drax Power's ability to trade electricity. BHP Billiton believes this will generate significant cost savings in relation to the costs of credit support facilities contemplated in other proposals. 6 There are a number of important commercial services which are necessary for the ongoing operation of the Drax power station. It is a condition of BHP Billiton's Offer that restructured commercial arrangements are put in place in the three key areas of O&M (by 30 March 2004), trading services (by 30 March 2004) and trading guarantee facilities (by the Effective Date). BHP Billiton believes it can add significant value through the provision of a number of commercial services and, if the Company so requires, would be happy to assist in the following respects: 6.1 BHP Billiton believes that it is desirable to enter into long-term offtake agreements on up to two of the six Drax units in order to ensure a minimum level of stable cash flows and reduce the operational risk of trading all six units as a merchant plant. BHP Billiton (through one of its affiliates) will be happy to assist in structuring such contracts. 6.2 BHP Billiton believes that it can offer significant cost savings to the Company in relation to its trading activities by offering certain management services to Drax Power, including confirmation, 24-hour operation contract and risk management services, accounting, settlements and invoicing services. At the option of Senior Creditors and the Company, BHP Billiton (or an affiliate) will make available trading facilities, systems and resources at BHP Billiton (or its affiliates) offices enabling relevant personnel to access BHP Billiton's (or its affiliate's) trading systems and in particular its coal, power and CO2 trading expertise. An agency fee would be payable in respect of the provision of these services that BHP Billiton believes would provide substantial ongoing cost savings to the Company. 6.3 BHP Billiton believes that the Company could make substantial savings in relation to O&M services compared with the AES and IP proposals, which include significant management fees for O&M services. In addition, both AES and IP have proposed a long-term O&M contract that can only be cancelled under very limited circumstances. BHP Billiton believes that it can add considerable value to the restructuring by procuring specialist O&M personnel from Eskom. 6.4 BHP Billiton (or an affiliate) would also provide coal price hedging services allowing Drax the option to fix forward coal prices for up to three years, enhancing its control over cash flows, timing of pricing and spark spreads. 7 Additional information on the terms of this BHP Billiton Offer are set out in the various Schedules attached to this BHP Billiton Offer Letter. 8 The BHP Billiton Offer will lapse at 5.00 p.m. (London time) on 29 August 2003 unless the Company and the Senior Creditors Committees have by then entered into an exclusive relationship with BHP Billiton by countersigning this letter and returning it to us, thereby confirming that they will not enter 4 into or continue any negotiations or discussions with any person other than BHP Billiton with respect to the Cash-Out Options and the other matters contemplated by this BHP Billiton Offer Letter, provided that such exclusivity shall cease on 31 December 2003 or, if earlier, (i) the date on which this offer lapses or is otherwise terminated, or (ii) the date of execution of mutually acceptable documentation required for the Restructuring (including the coal supply agreement and shareholders agreement) and satisfaction of all conditions precedent thereto (the "EFFECTIVE DATE"). On behalf of BHP Billiton, we very much appreciate your consideration of this offer and look forward to your response. BHP Billiton believes that its offer proposes a financial and commercial restructuring of the Company to the benefit of the Senior Creditors. BHP Billiton sees this offer as forming the basis of a long-term mutually beneficial relationship with the Company. In addition, we believe that along with Eskom, we offer a package that lowers the risk and enhances value to the Senior Creditors. Please feel free to contact Rowen Bainbridge (on 0207 802 4015) or Paul Adair (0207 802 4036) to discuss any questions or issues that you may have with respect to this letter.

The detailed terms and conditions, including the right to appoint directors, rights and restrictions on the transfer of shares and voting rights will be agreed with the Senior Creditors Committees.

Certain other reserved matters such as changes to the coal supply arrangements will require unanimity. 1.2 BHP Billiton requires to appoint such number of directors as is proportionate to its overall shareholding interest. Such director(s) would have veto rights over certain reserved matters, including the appointment of identified key individuals, such as the station manager and the implementation of a commodity price risk management policy. 1.3 BHP Billiton is supportive of the proposal to provide a period of stability following the Restructuring within which the Drax power station may operate, by linking the A-2 Debt, A-3 Debt and Equity (including any option to hold Equity) for an initial period on terms to be agreed with the Senior Creditors Committees. 2 The BHP Billiton Offer is subject to: 2.1 prior to the Effective Date there being, in BHP Billiton's opinion, no material adverse change in the assets, operations or liabilities (but excluding any such change arising out of a change in commodity prices in the UK market) of the Company and its affiliates or in the forecasts with regard to capital and operating expenditure and taxes compared to the information: (i) contained within the Form 6K filing dated 16 July 2003 (SEC file #:333-13096) and/or (ii) as disclosed to BHP Billiton during the due diligence referred to in paragraph 2.4 below;

or 3.3.2 enter into any agreement with any person other than BHP Billiton (or any of its affiliates) with respect to the supply of coal to the Drax power station except with the prior consent of BHP Billiton, which shall not be unreasonably withheld or delayed;

(b) second, to make scheduled repayments of principal on the A-1 Debt; (c) third, to make a deposit to the DSRA of the amount required so that funds standing to the credit of the DSRA are equal to the interest on A-1 Debt falling due on the next two interest payment dates; (d) fourth, to make payments of interest on the A-2 Debt (including deferred interest and hedging of A-2 Debt interest); (e) fifth, to fund the A-2 Debt Interest Reserve to the required amount; (f) sixth, to make a deposit to the DSRA of an amount so that the balance on the DSRA is equal to the scheduled amortisation of principal on A-1 Debt falling due on the next two interest payment dates;

(k) eleventh, to make prepayments and repayments as follows: (i) at any time after the principal amount outstanding of the A-1 Debt is (pound)200,000,000 or more, to prepay the A-1 Debt, with prepayments of A-1 Debt being applied to the amortisation profile of the A-1 Debt in inverse order of maturity; and (ii) at any time after the principal amount outstanding of the A-1 Debt is less than (pound)200,000,000, to prepay A-1 Debt and prepay A-2 Debt on a pro rata basis as to the outstanding principal amount of A-1 Debt and A-2 Debt immediately prior to the prepayment. Prepayments of the A-1 Debt will be applied to the amortisation profile of the A-1 Debt in inverse order of maturity; (l) twelfth, if the A-1 Debt and the A-2 Debt have been repaid in full, to pay A-3 Debt deferred interest; - ------------- 2 Structuring of hedging facilities and ranking in Cash Flow Waterfall to be discussed between the Senior Creditors Committees and BHP Billiton. 9 (m) thirteenth, if the A-1 Debt and the A-2 Debt have been repaid in full, to prepay principal on the A-3 Debt; (n) fourteenth, if the A-1 Debt, the A-2 Debt and the A-3 Debt have been repaid in full, to pay B Debt deferred interest; and (o) fifteenth, if the A-1 Debt, the A-2 Debt and the A-3 Debt have been repaid in full, to prepay principal on the B Debt. Proceeds received in respect of the TXU Claim will be excluded from the Cash Flow Waterfall.

The amount withheld on account of UK corporation tax from TXU Claim proceeds will be equal to 30% (or, if different, the prevailing UK corporation tax rate in the tax year such payment in respect of the TXU Claim is received). The amount withheld will be paid into an escrow account. If payment had been received in respect of the TXU Claim, and the relevant company in the Drax group has a liability in respect of UK corporation tax, an amount shall be applied to pay such tax amount when such amount falls due for payment. If, having paid the full UK corporation tax liability of the relevant company, there remains a positive balance in the escrow account, such positive balance shall be applied to prepay the principal of the B Debt. BHP Billiton is prepared to discuss any appropriate structure which may achieve a mutually beneficial result for the parties. 10 SCHEDULE 3 TIMELINE OF THE BHP BILLITON OFFER 29 AUG 2003: Last date for acceptance of BHP Billiton Offer. The Company and the Senior Creditors Committees enter into exclusive negotiations with BHP Billiton as the preferred counterparty. 15 SEP 2003: Agreed heads of terms for coal supply agreement. 30 SEP 2003: Financial Term Sheet agreed for the Restructuring and agreed heads of terms for the shareholders agreement and Trading Guarantee Facility. 31 DEC 2003: Deadline for the completion of the Restructuring including the satisfaction of any conditions relating thereto and signature of the coal supply agreement, shareholders agreement and the Trading Guarantee Facility documentation. 31 MARCH 2004: Agreed O&M agreement and trading services agreement. 11 SCHEDULE 4: AES DRAX HOLDINGS LIMITED: Our restructuring proposal follows, in general, the key structural terms of the 14 August 6K. However, following consultation with Senior Creditors and their advisors, it includes a number of specific structural differences from that proposal that we believe add value to the terms of the Restructuring. The principal differences are: (i) flexibility to consider any proposals which have been developed on the treatment of the Hedge Termination Payments and any reinstated interest rate hedges (see section 1.2.1); (ii) no cash-out option for the B Debt.

The indicative termination payments, if all positions were to be terminated, are included in the above table. The termination value of hedge contracts is subject to market prices and may therefore increase or decrease from the estimated amount included in the document. The treatment of the hedge positions of the Hedging Banks in the Restructuring requires further discussion with the Hedging Banks, the Senior Creditors Committees and BHP Billiton. 5 The amount of A-2 Debt outstanding immediately following the Restructuring will be lower to the extent that the Cash-Out Option is exercised by Senior Creditors. 6 The amount of the A-3 Debt outstanding immediately following the Restructuring will be equal to the sum of the debts owed to the Senior Creditors (as set out in the table in section 1.1 above), less the sum of the other tranches of the Restructured Debt and will be lower to the extent that (a) the Project Funds are used to fund any Cash-Out Option and (b) the hedging contracts with Hedging Banks are not terminated. The figure shown is based on an exchange rate of $1.512 = (pound)1, the Fed Funds Rate on 27 July 2000 being the rate applicable at the time of the issue of the Senior Bonds. The actual exchange rate used will be that as at a reference date prior to the Restructuring. The termination value of hedge contracts is subject to market prices and may therefore increase or decrease from the estimate included in this document. 7 This is the aggregate amount of the TXU Claim (net of VAT payable in respect thereof). There is no assurance that the full amount of the TXU Claim will ultimately be recovered or that the AES Drax Companies will have tax losses to offset against any attributable income. 14 ----------------------- ------------------------ -------------- --------------- FINAL DEBT STERLING EQUIVALENT MATURITY INTEREST RATE ----------------------- ------------------------ -------------- --------------- Equity 100% ownership (indirect) of Drax Power Station ----------------------- ------------------------ -------------- --------------- Trading Guarantee Up to(pound)100 Facility million(8) ----------------------- ------------------------ -------------- --------------- Interest Rate Hedging(9) ----------------------- ------------------------ -------------- --------------- 1.2.2 RIGHT TO RECEIVE PRO RATA SHARE OF RESTRUCTURED DEBT One overriding principle in the Restructuring is that for each (pound)1 of senior secured indebtedness owed to a Senior Creditor such Senior Creditor will be entitled to the same participating interest in each of the tranches of debt. Accordingly, each Senior Bank, Senior Bondholder and Hedging Bank (to the extent their hedging agreement is terminated) will be allocated, in proportion to its current relative holdings of the Bank Loans, Senior Bonds or rights to Hedge Termination Payments, as the case may be: (i) participations in A-1 Debt and B Debt; and (ii) the right to receive a combination of: (a) participations in A-2 Debt and A-3 Debt (together with the A-1 Debt and B Debt, the "RESTRUCTURED Debt"); and/or (b) cash pursuant to the exercise by such Senior Creditor of its Cash-Out Option described in section 1.3 - The Cash-Out Option below. 1.2.3 SENIOR CREDITORS' RIGHT TO ALL EQUITY The Senior Creditors will, under the terms of this Restructuring proposal, have the right to become indirect owners of the whole of the equity of Drax Power in proportion to their holdings of A-3 Debt after the exercise of the Cash-Out Option. See section 1.4 - Drax Power Station Ownership. The BHP Billiton Offer does not provide for any consideration to be provided to AES or the AES Drax Energy Limited bondholders. - ------------- 8 To be finalised following agreement of a revised electricity trading policy for the AES Drax Companies. In addition, it is intended that at completion of the Restructuring a cash balance of up to (pound)50,000,000 will be available from existing Company cash resources to Drax Power for working capital purposes, subject to the cashflow cycle. 9 Discussions required between the Hedging Banks, the Senior Creditors Committees and BHP Billiton as to the treatment of hedge positions in the Restructuring. 15 1.2.4 RESTRUCTURED TRANCHES OF DEBT The Restructured Debt has been separated into tranches in order to provide for: (i) a first ranking tranche of debt(10), the A-1 Debt, of (pound)400 million with the following scheduled amortisation profile and a final maturity date of 2015: - ------------------------- --------------------------------- AMORTISATION ((POUNDS YEAR STERLING) MILLION)(11) - ------------------------- --------------------------------- 2007 10 - ------------------------- --------------------------------- 2008 20 - ------------------------- --------------------------------- 2009 55 - ------------------------- --------------------------------- 2010 55 - ------------------------- --------------------------------- 2011 55 - ------------------------- --------------------------------- 2012 55 - ------------------------- --------------------------------- 2013 50 - ------------------------- --------------------------------- 2014 50 - ------------------------- --------------------------------- 2015 50 - ------------------------- --------------------------------- Interest on A-1 Debt will be payable on a semi-annual basis. A-1 Debt will have the benefit of certain prepayment rights as well as a Debt Service Reserve Account (as defined in section 2.1.1) funded at completion of the Restructuring to an amount equal to the interest payments falling due on the two interest payment dates following the Restructuring and, thereafter, funded in accordance with the Cash Flow Waterfall (as described in section 2.2 - Cash Flow Waterfall) to a level equal to the interest and scheduled principal payments on the A-1 Debt falling due on the two interest payment dates following the relevant interest payment date; (ii) a second ranking tranche, the A-2 Debt, of up to (pound)460 million which will have no fixed amortisation profile, however, the outstanding principal balance will fall due for payment in 2015. Interest on the A-2 Debt will be payable on a semi-annual basis after payment of interest on the A-1 Debt, any hedging specific to the A-1 Debt(12) scheduled principal payments on the A-1 Debt, and a cash sweep into the Debt Service Reserve Account to ensure a required balance equal to 12 months' interest payments on A-1 Debt; A-2 Debt will also benefit from a 1.0 x look-forward test/reserve of at least six months. If there are insufficient funds to pay interest on the A-2 Debt, - ------------- 10 This is subject to the priority of the Trading Guarantee Facility (see section 1.5 - Electricity Trading Support for BHP Billiton's proposal). 11 Each annual scheduled amortisation shown above will be payable in two equal instalments on the semi-annual interest payment dates in each such year, provided that there will only be one payment in 2015. 12 Structure of hedging and ranking in Cash Flow Waterfall to be discussed with the Hedging Banks and Senior Creditors Committees. 16 interest will be deferred . Repayment of the principal on the A-2 Debt will not occur prior to the principal amount of the A-1 Debt reducing to below (pound)200 million and will, thereafter, be dependent upon there being sufficient funds available for such purpose in accordance with the Cash Flow Waterfall; (iii) a third ranking tranche, the A-3 Debt, of up to (pound)135.455 million. Unpaid interest on the A-3 Debt will be deferred (but not capitalised). The A-3 Debt will not receive cash payments of deferred interest or principal until the A-1 Debt and A-2 Debt have been repaid in full; (iv) a fourth ranking tranche, the B Debt, of(pound)338.4 million whose primary source of repayment will be payments received in relation to the TXU Claim and will have first ranking security over the TXU Claim. The B Debt will also have security over the Principal Drax Assets ranking junior to the A-3 Debt. Interest will accrue on the B Debt and will be paid in accordance with the Cash Flow Waterfall, where it ranks behind scheduled A-1 Debt payments, A-2 Debt and A-3 Debt interest payments and, inter alia, deposits to a debt service reserve account to ensure a required balance equal to 12 months' interest and scheduled principal payments on the A-1 Debt. If there are insufficient funds to pay interest on the B Debt, interest will be deferred, but not capitalised. Proceeds of the TXU Claim will be used to repay the principal amount of the B Debt and interest thereon. The principal amount outstanding of the B Debt will only otherwise be repaid once the A-1 Debt, the A-2 Debt and the A-3 Debt have been repaid in full. See section 2.2 - Cash Flow Waterfall for further details. All Restructured Debt will accrue interest as from 1 July 2003 (see section 1.3.5 - Accrual of Interest). 1.3 THE CASH-OUT OPTION 1.3.1 OPTION TO SELL A-2 DEBT AND A-3 DEBT As part of the Restructuring, each Senior Creditor will have the option (the "CASH-OUT OPTION") to sell, at a discount (see section 1.3.2. below), all of its participation in the A-2 Debt and the A-3 Debt, provided that a Senior Creditor may tender on a pro-rata basis part of its A-2 Debt and A-3 Debt. Any such sales will be completed concurrently with the issuance of the Restructured Debt. A Senior Creditor that exercises its Cash-Out Option will forego any right to receive Equity (as defined in section 1.4.1 - Ownership below) for any A-3 Debt sold in the Cash-Out Option. The Cash-Out Option is designed to provide Senior Creditors with an alternative in order to realise immediate cash value for the holding of A-2 Debt, A-3 Debt and Equity which would otherwise be allocated to them. 1.3.2 DISCOUNT PRICE Under the Cash-Out Option, the discount price for a Senior Creditor's participation in A-3 Debt will be 1% of its original principal amount. The discount price for a 17 Senior Creditor's participation in A-2 Debt will be 70% of its original principal amount. 1.3.3 SOURCE OF FUNDS Two sources of funds will be available to make payments to Senior Creditors who elect to accept the Cash-Out Option ("CASH-OUT FUNDS"): (i) the amount, being at a minimum (pound)30,000,000, which will be available to the AES Drax Companies (after taking into account fees and expenses in connection with the Restructuring and working capital requirements subject to the cashflow cycle) is that amount of cash (the "PROJECT FUNDS") in excess of funds required to make payment in full of amounts in the Cash Flow Waterfall down to and including A-2 Debt interest on 31 December, 2003 and, therefore, is yet to be finally determined; and (ii) up to (pound)95,000,000 (or such greater amount as is referred to below) is to be made available by BHP Billiton or one of its affiliates (the "BHP BILLITON FUNDS"). The Cash-Out Funds for the Cash-Out Option will be made available as follows: (i) first, by the AES Drax Companies from Project Funds up to(pound)30,000,000; (ii) second, the amount of incremental Project Funds in excess of the (pound)30,000,000 that the Company and Senior Creditors elect to use until all Project Funds are exhausted; and (iii) finally, any additional amounts that are required will be funded from BHP Billiton Funds until BHP Billiton Funds are exhausted. It is possible that the amount of BHP Billiton Funds might be increased if the Cash-Out Option is taken up by Senior Creditors in such a manner that the (pound)95,000,000 would prove to be insufficient. If demand for the Cash-Out Option is so strong that additional funds are required, BHP Billiton reserves the right to increase the amount of the BHP Billiton Funds and, if necessary, will endeavour to obtain additional funding from third parties. If Cash-Out Funds are insufficient to make payments in full to all the Secured Creditors who elect to accept the Cash-Out Option (each an "ELECTING SECURED CREDITOR") then each Electing Secured Creditor will be "scaled back". All Cash-Out Funds will be used so that each Electing Secured Creditor will sell its A-2 Debt and A-3 Debt pro rata to its claim as a Secured Creditor relative to the aggregate of claims of all Electing Secured Creditors. Each Electing Secured Creditor will then receive A-2 Debt and A-3 Debt which remains unsold under its exercise of the Cash-Out Option and, therefore, a corresponding portion of the Equity. 1.3.4 CONSEQUENCES OF CASH-OUT OPTION To the extent that Project Funds are used to purchase participations in A-2 Debt and A-3 Debt under the Cash-Out Option, the outstanding amount of such debt will be retired, thereby deleveraging the Drax project. To the extent that BHP Billiton purchases participations in A-2 Debt and A-3 Debt, it will become a Senior Creditor 18 holding Restructured Debt. In addition, BHP Billiton will have the option to receive Equity in proportion to the amount of A-3 Debt it purchases. 1.3.5 ACCRUAL OF INTEREST No interest will be paid in respect of the debt to be compromised in the Restructuring which is held by the Senior Banks and the holders of the Senior Bonds for the period from and including 1 July 2003 to the completion of the Restructuring. However, interest will accrue in respect of the Restructured Debt as from 1 July 2003 as if such debt had been issued on such date, and will be paid in accordance with the Cash Flow Waterfall. Appropriate treatment will need to be agreed in relation to those Senior Creditors who exercise the Cash-Out Option. 1.4 DRAX POWER STATION OWNERSHIP 1.4.1 OWNERSHIP The indirect ownership of the Drax power station will be transferred to the holders of the A-3 Debt in the form of all of the shares (the "EQUITY") in a holding company (the "PARENT") which indirectly owns all of the equity in Drax Power. As indicated under section 1.3 - The Cash-Out Option above, if a Senior Creditor exercises the Cash-Out Option, then it will not receive any Equity for any A-3 Debt sold under the Cash-Out Option. In addition: (i) to the extent that the Cash-Out Option is funded by Project Funds, Equity corresponding to A-3 Debt that is prepaid will not be issued; and (ii) to the extent that the Cash-Out Option is funded by BHP Billiton Funds, BHP Billiton will have the option, at no additional cost, to become the owner of the Equity corresponding to the A-3 Debt purchased by BHP Billiton. 1.4.2 RESTRICTIONS ON TRADING In order to provide a period of stability following the Restructuring within which the Drax power station may operate, the A-2 Debt, A-3 Debt and Equity (including any option to hold Equity) (together, the "LINKED SECURITIES") will remain "linked" for an initial period13. During this period, no holder of Linked Securities may sell any single Linked Security without also selling proportionate amounts of its other Linked Securities. 1.5 ELECTRICITY TRADING SUPPORT As mentioned in paragraph 5 of the BHP Billiton Offer Letter, Drax Power will require substantial credit support to continue its electricity trading activities following the Restructuring. If Drax Power is no longer required to provide cash collateral as credit support this will enhance the liquidity of the Drax power station and provide cash for other purposes, including working capital and funding the Cash-Out Option. BHP Billiton is willing to arrange from closing of the Restructuring, subject to agreement of satisfactory terms by 30 September 2003 and internal BHP Billiton credit approval, a (pound)100,000,000 Trading 19 Guarantee Facility to facilitate Drax Power's ability to trade electricity. A portion of this Trading Guarantee Facility may take the form of credit lines with a BHP Billiton entity. Facility utilisation fees shall be calculated based on the aggregate risk exposures generated by Drax Power's trading activities, providing a more efficient facility than traditional credit facilities. This Facility shall, at all times, have first ranking security interest (senior to the Senior Creditors) over the Principal Drax Assets. 2 SECTION 2 - DETAILED TERMS OF THE RESTRUCTURING PROPOSAL 2.1 RESTRUCTURED DEBT 2.1.1 A-1 DEBT (PRINCIPAL AMOUNT: (POUND)400 MILLION): RANKING: A-1 Debt will have the benefit of a second ranking security interest over all of the properties, assets and shares of the AES Drax Companies (other than recoveries on the TXU Claim which will be subject to a first ranking security interest for the benefit of the B Debt) (such properties, assets and shares other than the TXU Claim, the "PRINCIPAL DRAX ASSETS"). A-1 Debt has a second ranking security interest over the Principal Drax Assets solely because it ranks after the security interest in respect of the Trading Guarantee Facility (up to(pound)100 million). Otherwise, A-1 Debt has a security interest that ranks ahead of all other tranches of the Restructured Debt INTEREST RATE: Libor plus a margin of 2.5%. INTEREST PAYMENT Semi - annual. DATE: FINAL MATURITY 30 June 2015 DATE: AMORTISATION: Scheduled amortisation to be paid in each year in equal instalments on semi-annual interest payment dates and on the Final Maturity Date as follows: 2007: (pound)10 million 2008: (pound)20 million 2009: (pound)55 million 2010: (pound)55 million 2011: (pound)55 million 2012: (pound)55 million 2013: (pound)50 million 2014: (pound)50 million 20 2015: (pound)50 million PREPAYMENT: Until the principal amount of the A-1 Debt has reduced below (pound)200,000,000, cash available for debt service will, after payment of A-1 Debt interest and hedging, A-1 Debt scheduled amortisation, funding the DSRA (defined below) for 12 months' A-1 Debt interest and scheduled principal, payment of A-2 Debt interest (including deferred interest and, if applicable, funding the A-2 Debt Interest Reserve) and interest on the A-3 Debt and B Debt be applied solely to prepayment of A-1 Debt principal in inverse order of the scheduled amortisation profile. At any time after the principal amount of the A-1 Debt has reduced below (pound)200m, excess cash available for debt service will, after payment of the amounts referred to in the immediately preceding paragraph, be applied on a pro rata basis to (a) prepayment of A-1 Debt principal, in inverse order of the scheduled amortisation profile, and (b) A-2 Debt principal, (for the avoidance of doubt, this means proportionally to the outstanding amount of A-1 Debt and A-2 Debt immediately prior to the prepayments). PRIORITY OF See section 2.2 - Cash Flow PAYMENTS: Waterfall. DEBT SERVICE A debt service reserve account (the RESERVE ACCOUNT: "DEBT SERVICE RESERVE ACCOUNT" or "DSRA") will be established immediately on the completion of the Restructuring from funds available in the Drax project in an amount equal to the interest falling due on the A-1 Debt on the next two interest payment dates. Following the Restructuring, after payment of A-1 Debt interest and hedging and scheduled A-1 Debt amortisation, cash available for debt service will be transferred to the DSRA to the extent required to ensure that the required balance thereon is equal to the next two A-1 Debt interest payments. In addition, after payment of A-2 Debt interest (including deferred interest and, if applicable, funding the A-2 Debt Interest Reserve), cash available for debt service of up to the amount of scheduled A-1 Debt amortisation falling due on the next two interest payment dates will be transferred to the DSRA. To the extent that the funds credited to the DSRA as of an A-1 Debt interest payment date exceed the required DSRA balance determined as of such date, the excess may be withdrawn and used to make payments in 21 accordance with the Cash Flow Waterfall. COVENANT PACKAGE: The covenant package is to be negotiated, but is expected to have the level of protections similar to those in the current Bank Loans. ACCELERATION AND To be discussed with the Senior ENFORCEMENT: Creditors Committees on the basis of the proposal set out in the 30 June 6K. CHANGE OF To be discussed with the Senior CONTROL: Creditors Committees on the basis of the proposal set out in the 30 June 6K. CREDIT RATING: To be discussed with the Senior Creditors Committees. 2.1.2 A-2 DEBT (PRINCIPAL AMOUNT: UP TO (POUND)460 MILLION): RANKING: A-2 Debt will have the benefit of a third ranking security interest over the Principal Drax Assets, ranking in point of security after the amounts owing under the Trading Guarantee Facility and the A-1 Debt. INTEREST RATE: Libor plus a margin of 4%. INTEREST PAYMENT: Interest on the A-2 Debt will be payable on a semi-annual basis after payment of interest on the A-1 Debt and hedging, scheduled principal payments on the A-1 Debt, and a cash sweep into the Debt Service Reserve Account to ensure a required balance equal to 12 months interest payments on A-1 Debt. Unpaid interest is deferred (not capitalised) and bears interest at the same rate. A-2 DEBT INTEREST There will be a six month (18 RESERVE: months on or before 31 December 2006) look-forward test for A-2 Debt interest on a 1.0 x debt service cover ratio, and to the extent such test is not passed, an amount equal to the shortfall will (in accordance with the Cash Flow Waterfall) be placed in a reserve account (the "A2 DEBT INTEREST RESERVE"). Amounts standing to the credit of the A-2 Debt Interest Reserve would be used to make payments of interest and scheduled principal on the A-1 Debt before making payments of interest on the A-2 Debt if there were insufficient funds available in the Cash Flow Waterfall for such purpose and if the DSRA had been fully utilised. FINAL MATURITY 30 June 2015. DATE: AMORTISATION: No scheduled amortisation of principal. Once the principal amount outstanding of A-1 Debt is less than(pound)200 million, excess cash available for debt service will, after payment of the A-1 Debt interest and hedging, 22 scheduled A-1 Debt principal amortisation, funding the DSRA for 12 months' A-1 Debt interest, payment of A-2 Debt interest (including deferred interest and, if applicable, funding the A-2 Debt Interest Reserve) and interest on the A-3 Debt and B Debt and hedging, funding the DSRA for 12 months' A-1 debt scheduled principal, be applied to prepayment of A-1 Debt principal and A-2 Debt principal on a pro rata basis.

CASH-OUT OPTION: Senior Creditors who are otherwise entitled to a holding of A-2 Debt have the alternative of exercising the Cash-Out Option described in section 1.3 - The Cash-Out Option above. To the extent so exercised and to the extent the purchase is funded from Project Funds, the A-2 Debt so purchased will be cancelled. For further details, see section 1.3 - The Cash-Out Option above. CHANGE OF To be discussed with the Senior CONTROL: Creditors Committees on the basis of the proposal set out in the 30 June 6K. 2.1.3 A-3 DEBT: PRINCIPAL AMOUNT: UP TO (POUND)135.455 MILLION RANKING: A-3 Debt will have the benefit of a fourth ranking security interest over the Principal Drax Assets. INITIAL PRINCIPAL The initial principal amount of the AMOUNT A-3 Debt will, subject to reduction in accordance with the Cash-Out Option, be the difference between: (i) the aggregate amount of the Senior Creditors' indebtedness being ' compromised by the Restructuring; and (ii) the aggregate amount of the A-1 Debt, A-2 Debt and B Debt (before any reduction of any amount in respect of Senior Creditors exercising the Cash-out Option). INTEREST RATE: Libor plus a margin of 5%. INTEREST PAYMENT Interest on A-3 Debt shall be DATE: deferred (but not capitalised) if there are insufficient funds available in the Cash Flow Waterfall for such purpose. A-3 DEBT There will be a six month (18 INTEREST months on or before 31 December RESERVE: 2006) look-forward test for A-3 Debt interest 23 on a 1.0 x debt service cover ratio, and to the extent such test is not passed, an amount equal to the shortfall will (in accordance with the Cash Flow Waterfall) be placed in a reserve account (the "A-3 DEBT INTEREST RESERVE"). Amounts standing to the credit of the A-3 Debt Interest Reserve would be used to make payments of interest and scheduled principal on the A-1 Debt or the A-2 Debt before making payments of interest on the A-3 Debt if there are insufficient funds available in the Cash Flow Waterfall for such purpose. AMORTISATION: A-3 Debt principal will only be paid after all of the A-1 Debt and A-2 Debt have been paid in full. COVENANT PACKAGE: Limited covenant package to be agreed. ACCELERATION AND To be discussed with the Senior ENFORCEMENT: Creditors Committees on the basis of the proposal set out in the 30 June 6K. CASH-OUT OPTION: Senior Creditors who are otherwise entitled to a holding of A-3 Debt have the alternative of exercising the Cash-Out Option described in section 1.3 - The Cash-Out Option above. To the extent so exercised and to the extent the purchase is funded from Project Funds, the A-3 Debt so purchased will be cancelled. For further details, see section 1.3 - The Cash-Out Option above. CHANGE OF To be discussed with the Senior CONTROL: Creditors Committees on the basis of the proposal set out in the 30 June 6K. EQUITY: The Equity will be issued to holders of the A-3 Debt immediately after completion of the Cash-Out Option in proportion to such holdings. 2.1.4 B DEBT (PRINCIPAL AMOUNT: (POUND)338,400,000): SOURCE OF PAYMENT The principal source of funds for AND SECURITY: the payment of B Debt is the proceeds to be received from the TXU Claim. B Debt will have a first ranking security interest over the TXU Claim proceeds. The B Debt will have a fifth ranking security interest over the Principal Drax Assets. To the extent the proceeds of the TXU Claim are insufficient to repay the B Debt (and deferred interest thereon), payment of such remaining B Debt will be made in accordance with the Cash Flow Waterfall (see section 2.2 - Cash Flow Waterfall below). INTEREST RATE: Libor plus a margin of 2%. INTEREST PAYMENT: B Debt interest will be deferred (but not capitalised) to the extent excess cash is not available after payment of 24 interest on the A-1 Debt and hedging, scheduled principal payments on the A-1 Debt, funding the DSRA for 12 months' A-1 Debt interest and scheduled principal and payment of A-2 Debt interest (including deferred interest and, if applicable, funding the A-2 Debt Interest Reserve) and hedging and payment of A-3 Debt interest (including deferred interest and, if applicable, funding the A-3 Debt Interest Reserve) (see section 2.2 - Cash Flow Waterfall below).

Amounts standing to the credit of the B Debt Interest Reserve would be used to make payments of interest and scheduled principal on the A-1 Debt, the A-2 Debt, or the A-3 Debt before making payments of interest on the B Debt if there are insufficient funds available in the Cash Flow Waterfall for such purpose. AMORTISATION: No fixed scheduled amortisation. B Debt will be paid on receipt of proceeds of the TXU Claim and otherwise once the A-1 Debt, A-2 Debt and A-3 Debt have been repaid in full.

ITEM 2 The Directors of AES Drax Holdings Limited c/o Kempson House Camomile Street London EC3A 7AN 21 August 2003 Dear Sirs DRAX - BHP BILLITON'S OFFER We are pleased to submit this offer by BHP Billiton plc ("BHP BILLITON") to provide support to facilitate the restructuring of the senior secured debt and other contractual arrangements of AES Drax Holdings Ltd (the "Company") and certain of its affiliates, including AES Drax Power Limited ("DRAX POWER") (the "BHP BILLITON Offer"). While the BHP Billiton Offer is made by BHP Billiton solely on the terms and conditions set out in this offer letter (the "BHP BILLITON OFFER LETTER") and its schedules (the "SCHEDULES"), the BHP Billiton Offer to a large extent follows the restructuring proposals as laid out in (i) the 30 June 2003 Form 6K filing to the US Securities and Exchange Commission (SEC File #333-13096) ("30 JUNE 6K") and (ii) the 14 August 2003 Form 6K filing to the US Securities and Exchange commission (SEC File #333-13096) ("14 AUGUST 6K") with a view to facilitating the completion of the restructuring of the secured debt of the AES Drax Companies and the entering into of the commercial agreements as set out in BHP Billiton Offer Letter (the "RESTRUCTURING"). The BHP Billiton Offer includes a number of key commercial and economic terms, which we believe substantially enhance the terms of the Restructuring and as such maximise the ultimate recoveries for the Senior Banks, the Senior Bondholders and the Hedging Banks, whether or not they intend to exercise the Cash-Out Option. We strongly believe that an integrated financial and commercial partnership between BHP Billiton and/or certain of its affiliates and the Company and its relevant affiliates under which BHP Billiton (or an affiliate) provides coal supply and energy trading services, together with O&M expertise from Eskom Enterprises (Pty) Ltd, a wholly owned subsidiary of Eskom Holdings (Pty) Ltd ("ESKOM"), adds significant value to the restructuring by increasing the certainty of operating cashflows and mitigating key commodity and operational risks. BHP Billiton is the world's largest diversified resources company with a market capitalisation of (pound)26.2 billion and a strong balance sheet and credit rating. We are a major provider of both coal and natural gas to the power generation industry. In particular, BHP Billiton Energy Coal is the world's largest producer and marketer of sea-borne thermal coal. Our focus is on providing competitive energy solutions for our world-wide portfolio of power generation customers. The business is structured around a portfolio of world-class producing assets, which provide a unique multi-sourcing capability to service the major power markets of Europe and the United Kingdom in particular. We have a proven track record and are a respected partner in joint ventures worldwide. Eskom, the South African electricity utility company, operates 42,000 MW of power generation capacity, of which 37,000 MW comprises large coal-fired plants including seven power stations with capacity in 1 excess of 3,000 MW. Eskom is a key business partner of BHP Billiton in South Africa and the two companies have a strong relationship extending over many years. We recognise the dual needs of the Senior Creditors to meet the short-term financial objectives of the Restructuring, while at the same time ensuring the long-term viability of the Company. We believe that the BHP Billiton Offer demonstrates a clear differentiation in value from the other proposals received by the Company and provides for increased long-term security for the Senior Creditors through a unique and distinctive set of capabilities and service offerings. The main points of the BHP Billiton Offer are as follows: o BHP Billiton will provide substantial funding for the Cash-Out Option with a significant premium to other offers based on a similar financial structure. o BHP Billiton offers to provide a unique suite of value-added fuel, finance, O&M and commodity services that creates substantial value for the Principal Drax Assets and does not diminish commercial control or reduce flexibility for Senior Creditors. o The BHP Billiton Offer is an integrated solution that provides clarity of outcome through the creation of a stable, on-going and viable entity with improved credit profile, lower cost base and reduced risk profile. o A partnership with BHP Billiton will bring to the AES Drax Companies all the credentials and capabilities of a world leading energy company with an excellent credit rating. This partnership will help the AES Drax Companies address the key challenges they face in their transition to consuming imported coal. o BHP Billiton is willing to arrange, at the Company's option, a (pound)100,000,000 Trading Guarantee Facility to facilitate Drax Power's ability to trade electricity. o BHP Billiton's Offer is not subject to or contingent on third party financing and does not result in any underwriting or other fees and charges being paid to BHP Billiton. BHP Billiton is willing to discuss placing amounts in escrow once a timetable for the overall Restructuring is agreed between BHP Billiton and the Senior Creditors. o BHP Billiton is able to work closely with the directors and Senior Creditors to meet the timetable of the Restructuring and address governance issues through discussion and negotiation. The summary terms of the BHP Billiton Offer are as follows1: 1 BHP Billiton offers to increase the price for creditors who decide to tender their A-2 Debt, C Debt (which will be renamed under the BHP Billiton Offer "A-3 DEBT"), and Equity (the "CASH-OUT OPTION") to 70 per cent. of the A-2 principal amount, a substantial improvement to the prices proposed by The AES Corporation ("AES"), International Power plc ("IP") and Goldman Sachs International ("GS"). BHP Billiton would also pay 1% for the A-3 Debt. BHP Billiton (or an affiliate) will provide up to (pound)95,000,000 of cash to support the funding of the Cash-Out Option ("BHP BILLITON FUNDS"). If demand for the Cash-Out Option is so strong that additional funds are required, BHP Billiton reserves the right to increase its participation and, if necessary, will endeavour to obtain additional funding from third parties wishing to purchase the A-2 Debt. To the extent that such - ------------- 1 Additional detailed information is contained in the various Schedules attached to the BHP Billiton Offer Letter. Any capitalised term used but not otherwise defined in this BHP Billiton Offer Letter shall have the meaning given to it in Schedule 4 of this Offer Letter. To the extent there is any inconsistency between the BHP Billiton Offer Letter and the Schedules, the terms of the BHP Billiton Offer Letter will prevail. 2 funding is not available, there would be a "scale back" as provided under section 1.3.3 of Schedule 4 of this BHP Billiton Offer Letter. To the extent that the Cash-Out Option is funded by BHP Billiton Funds, BHP Billiton will purchase pro-rata holdings of the A-2 Debt and the A-3 Debt and will have the option to become the owner of the Equity corresponding to the amount of the A-3 Debt purchased by BHP Billiton. 2 BHP Billiton will leave it to the option of the Company and the Senior Creditors whether they elect to use (pound)30,000,000 (the minimum required by BHP Billiton) of cash currently held by the Company or such higher amounts as may be deemed by the directors of the Company to be available in order to fund the Cash-Out Option. To the extent that the Company and the Senior Creditors elect to use more than (pound)30,000,000 of Project Funds, the Cash-Out Option will be funded as follows: first, (pound)30,000,000 of Project Funds will be used; second, the amount of incremental Project Funds in excess of the (pound)30,000,000 that the Company and the Senior Creditors elect to use, and finally any additional amounts that are required will be funded from BHP Billiton Funds until BHP Billiton Funds are exhausted. 3 The BHP Billiton Offer increases the margin on the A-2 Debt to 400bps. In addition, the terms and ranking of the B Debt and the A-3 Debt would be as follows: the A-3 Debt will rank behind the A-2 Debt but ahead of the B Debt, both in the Cash Flow Waterfall and with respect to its security over the Principal Drax Assets. The A-3 Debt will have fourth ranking security over the Principal Drax Assets and will accrue interest at a rate of Libor + 500bp, with the potential of having interest deferred if no funds are available under the Cash Flow Waterfall (similar to the A-2 Debt). The B Debt will accrue interest at the rate of Libor + 200bp with the potential of having interest deferred if no funds are available under the Cash Flow Waterfall (similar to the A-2 Debt and the A-3 Debt). The B Debt will have first ranking security over the claims against TXU Europe Energy Trading Limited and TXU Europe Group plc (the "TXU Claim"), as well as a fifth ranking security over the Principal Drax Assets. The holders of the B Debt however will not have any voting rights with respect to the release of their security over the Principal Drax Assets, the sale of the Company, or a recapitalisation of the balance sheet. The B Debt holders may (by a 75 per cent. majority) agree to compromise the TXU Claim or vote the interest of the AES Drax Companies in any insolvency in respect of the TXU Claim. The A-3 Debt holders shall have the first right of refusal to purchase all (or materially all) but not part of the Drax Principal Assets if the A-1 Debt holders and/or A-2 Debt holders have resolved to sell such assets. 4 It is a condition of BHP Billiton's Offer that BHP Billiton (or an affiliate) will enter an agreement for the supply of coal to the Drax power station for 15 years from January 2004. The agreement would be structured to ensure supply security for Drax Power, allowing it to retain maximum operational flexibility and mitigate risks in relation to Drax Power's most significant cost item. It would allow significant volume flexibility on coal supply which will be essential in ensuring an efficient transition to sourcing more imported coal as local domestic coal production declines. Subject to existing coal supply contracts, BHP Billiton (or an affiliate) would supply 100% of Drax's coal requirements on an exclusive basis from January 2006 to December 2010, and would thereafter continue to supply 80% of the plant's total requirements to 2018. The remaining 20% during this period would be subject to a competitive tender in which BHP Billiton (or an affiliate) would be entitled to participate. The price for coal supplied by BHP Billiton (or its affiliate) would be based on a competitive market index with a fixed-price adjustment for UK-based logistics. BHP Billiton (or an affiliate) will also assume management of the entire logistics chain of its coal supply to Drax Power, including sea freight, port facilities and rail transportation. BHP Billiton's position as a major coal supplier would enable it to minimise stockpile requirements and thereby reduce working capital requirements for 3 Drax Power, manage the blending of coals to ensure plant specifications are met and cover risks associated with delivery to the plant. (Further details are set out in Schedule 5). 5 Drax Power will require substantial credit support to continue its electricity trading activities following the Restructuring. If Drax Power is no longer required to provide cash collateral as credit support this will enhance the liquidity of the Drax power station and provide cash for other purposes, including working capital and funding the Cash-Out Option. BHP Billiton is willing to arrange, subject to agreement of satisfactory commercial terms by 30 September 2003, a (pound)100,000,000 Trading Guarantee Facility to facilitate Drax Power's ability to trade electricity. BHP Billiton believes this will generate significant cost savings in relation to the costs of credit support facilities contemplated in other proposals. 6 There are a number of important commercial services which are necessary for the ongoing operation of the Drax power station. It is a condition of BHP Billiton's Offer that restructured commercial arrangements are put in place in the three key areas of O&M (by 30 March 2004), trading services (by 30 March 2004) and trading guarantee facilities (by the Effective Date). BHP Billiton believes it can add significant value through the provision of a number of commercial services and, if the Company so requires, would be happy to assist in the following respects: 6.1 BHP Billiton believes that it is desirable to enter into long-term offtake agreements on up to two of the six Drax units in order to ensure a minimum level of stable cash flows and reduce the operational risk of trading all six units as a merchant plant. BHP Billiton (through one of its affiliates) will be happy to assist in structuring such contracts. 6.2 BHP Billiton believes that it can offer significant cost savings to the Company in relation to its trading activities by offering certain management services to Drax Power, including confirmation, 24-hour operation contract and risk management services, accounting, settlements and invoicing services. At the option of Senior Creditors and the Company, BHP Billiton (or an affiliate) will make available trading facilities, systems and resources at BHP Billiton (or its affiliates) offices enabling relevant personnel to access BHP Billiton's (or its affiliate's) trading systems and in particular its coal, power and CO2 trading expertise. An agency fee would be payable in respect of the provision of these services that BHP Billiton believes would provide substantial ongoing cost savings to the Company. 6.3 BHP Billiton believes that the Company could make substantial savings in relation to O&M services compared with the AES and IP proposals, which include significant management fees for O&M services. In addition, both AES and IP have proposed a long-term O&M contract that can only be cancelled under very limited circumstances. BHP Billiton believes that it can add considerable value to the restructuring by procuring specialist O&M personnel from Eskom. 6.4 BHP Billiton (or an affiliate) would also provide coal price hedging services allowing Drax the option to fix forward coal prices for up to three years, enhancing its control over cash flows, timing of pricing and spark spreads. 7 Additional information on the terms of this BHP Billiton Offer are set out in the various Schedules attached to this BHP Billiton Offer Letter. 8 The BHP Billiton Offer will lapse at 5.00 p.m. (London time) on 29 August 2003 unless the Company and the Senior Creditors Committees have by then entered into an exclusive relationship with BHP Billiton by countersigning this letter and returning it to us, thereby confirming that they will not enter 4 into or continue any negotiations or discussions with any person other than BHP Billiton with respect to the Cash-Out Options and the other matters contemplated by this BHP Billiton Offer Letter, provided that such exclusivity shall cease on 31 December 2003 or, if earlier, (i) the date on which this offer lapses or is otherwise terminated, or (ii) the date of execution of mutually acceptable documentation required for the Restructuring (including the coal supply agreement and shareholders agreement) and satisfaction of all conditions precedent thereto (the "EFFECTIVE DATE"). On behalf of BHP Billiton, we very much appreciate your consideration of this offer and look forward to your response. BHP Billiton believes that its offer proposes a financial and commercial restructuring of the Company to the benefit of the Senior Creditors. BHP Billiton sees this offer as forming the basis of a long-term mutually beneficial relationship with the Company. In addition, we believe that along with Eskom, we offer a package that lowers the risk and enhances value to the Senior Creditors. Please feel free to contact Rowen Bainbridge (on 0207 802 4015) or Paul Adair (0207 802 4036) to discuss any questions or issues that you may have with respect to this letter.

The detailed terms and conditions, including the right to appoint directors, rights and restrictions on the transfer of shares and voting rights will be agreed with the Senior Creditors Committees. BHP Billiton (or its affiliate) would not have the right to block a sale by the Senior Creditors of their Equity. If, following completion of the Restructuring, the Senior Creditors receive an offer, or enter into any process or negotiations for the sale of the Equity or the Principal Drax Assets, BHP Billiton requires notice of such offer, process or negotiations and the right to submit an offer for such Equity or the Principal Drax Assets for consideration by the relevant Senior Creditors. Certain other reserved matters such as changes to the coal supply arrangements will require unanimity. 1.2 BHP Billiton requires to appoint such number of directors as is proportionate to its overall shareholding interest. Such director(s) would have veto rights over certain reserved matters, including the appointment of identified key individuals, such as the station manager and the implementation of a commodity price risk management policy. 1.3 BHP Billiton is supportive of the proposal to provide a period of stability following the Restructuring within which the Drax power station may operate, by linking the A-2 Debt, A-3 Debt and Equity (including any option to hold Equity) for an initial period on terms to be agreed with the Senior Creditors Committees. 2 The BHP Billiton Offer is subject to: 2.1 prior to the Effective Date there being, in BHP Billiton's opinion, no material adverse change in the assets, operations or liabilities (but excluding any such change arising out of a change in commodity prices in the UK market) of the Company and its affiliates or in the forecasts with regard to capital and operating expenditure and taxes compared to the information: (i) contained within the Form 6K filing dated 16 July 2003 (SEC file #:333-13096) and/or (ii) as disclosed to BHP Billiton during the due diligence referred to in paragraph 2.4 below;

and 2.4 BHP Billiton finalising to its satisfaction its confirmatory technical and commercial due diligence process; which it expects to do by 15 September 2003. 3 In addition to the matters described in the BHP Billiton Offer Letter, it is a condition of BHP Billiton's Offer that, in accordance with the timeline set out in Schedule 3: 3.1 heads of terms for the coal supply agreement with BHP Billiton (or an affiliate) are agreed by 15 September 2003; 3.2 a financial term sheet for the Restructuring and heads of terms for the shareholders' agreement and Trading Guarantee Facility are agreed by 30 September 2003; 7 3.3 from the date on which your acceptance of this offer is received (the "ACCEPTANCE DATE") until the Effective Date, the Company (and in the case of paragraph 3.3.1 below, the Senior Creditors Committees) will not: 3.3.1 enter into or continue any negotiations or discussions with any person other than BHP Billiton with respect to the Cash-Out Options and the other matters relating to the Restructuring contemplated by this BHP Billiton Offer Letter; or 3.3.2 enter into any agreement with any person other than BHP Billiton (or any of its affiliates) with respect to the supply of coal to the Drax power station except with the prior consent of BHP Billiton, which shall not be unreasonably withheld or delayed;

and (ii) at any time after the principal amount outstanding of the A-1 Debt is less than (pound)200,000,000, to prepay A-1 Debt and prepay A-2 Debt on a pro rata basis as to the outstanding principal amount of A-1 Debt and A-2 Debt immediately prior to the prepayment. Prepayments of the A-1 Debt will be applied to the amortisation profile of the A-1 Debt in inverse order of maturity; (l) twelfth, if the A-1 Debt and the A-2 Debt have been repaid in full, to pay A-3 Debt deferred interest; - ------------- 2 Structuring of hedging facilities and ranking in Cash Flow Waterfall to be discussed between the Senior Creditors Committees and BHP Billiton. 9 (m) thirteenth, if the A-1 Debt and the A-2 Debt have been repaid in full, to prepay principal on the A-3 Debt; (n) fourteenth, if the A-1 Debt, the A-2 Debt and the A-3 Debt have been repaid in full, to pay B Debt deferred interest; and (o) fifteenth, if the A-1 Debt, the A-2 Debt and the A-3 Debt have been repaid in full, to prepay principal on the B Debt.

The amount withheld on account of UK corporation tax from TXU Claim proceeds will be equal to 30% (or, if different, the prevailing UK corporation tax rate in the tax year such payment in respect of the TXU Claim is received). The amount withheld will be paid into an escrow account. If payment had been received in respect of the TXU Claim, and the relevant company in the Drax group has a liability in respect of UK corporation tax, an amount shall be applied to pay such tax amount when such amount falls due for payment. If, having paid the full UK corporation tax liability of the relevant company, there remains a positive balance in the escrow account, such positive balance shall be applied to prepay the principal of the B Debt. BHP Billiton is prepared to discuss any appropriate structure which may achieve a mutually beneficial result for the parties. 10 SCHEDULE 3 TIMELINE OF THE BHP BILLITON OFFER 29 AUG 2003: Last date for acceptance of BHP Billiton Offer. The Company and the Senior Creditors Committees enter into exclusive negotiations with BHP Billiton as the preferred counterparty. 15 SEP 2003: Agreed heads of terms for coal supply agreement. 30 SEP 2003: Financial Term Sheet agreed for the Restructuring and agreed heads of terms for the shareholders agreement and Trading Guarantee Facility. 31 DEC 2003: Deadline for the completion of the Restructuring including the satisfaction of any conditions relating thereto and signature of the coal supply agreement, shareholders agreement and the Trading Guarantee Facility documentation. 31 MARCH 2004: Agreed O&M agreement and trading services agreement. 11 SCHEDULE 4: AES DRAX HOLDINGS LIMITED: Our restructuring proposal follows, in general, the key structural terms of the 14 August 6K. However, following consultation with Senior Creditors and their advisors, it includes a number of specific structural differences from that proposal that we believe add value to the terms of the Restructuring. The principal differences are: (i) flexibility to consider any proposals which have been developed on the treatment of the Hedge Termination Payments and any reinstated interest rate hedges (see section 1.2.1); (ii) no cash-out option for the B Debt. We also do not propose the option to eliminate the B tranche's claim on the Principal Drax Assets (see section 2.1); (iii) arrangement by BHP Billiton of the Trading Guarantee Facility at the Company's option (see section 1.5); (iv) willingness to enter into discussions with third parties to provide Cash-Out funding on the same terms as our proposal, should the BHP Billiton funds not be sufficient to satisfy all demand for the Cash-Out Option (see section 1.3.3); and (v) flexibility to discuss issues further with the Senior Creditors, on the basis of the proposal set out in the 30 June 6K.

The indicative termination payments, if all positions were to be terminated, are included in the above table. The termination value of hedge contracts is subject to market prices and may therefore increase or decrease from the estimated amount included in the document. The treatment of the hedge positions of the Hedging Banks in the Restructuring requires further discussion with the Hedging Banks, the Senior Creditors Committees and BHP Billiton. 5 The amount of A-2 Debt outstanding immediately following the Restructuring will be lower to the extent that the Cash-Out Option is exercised by Senior Creditors. 6 The amount of the A-3 Debt outstanding immediately following the Restructuring will be equal to the sum of the debts owed to the Senior Creditors (as set out in the table in section 1.1 above), less the sum of the other tranches of the Restructured Debt and will be lower to the extent that (a) the Project Funds are used to fund any Cash-Out Option and (b) the hedging contracts with Hedging Banks are not terminated. The figure shown is based on an exchange rate of $1.512 = (pound)1, the Fed Funds Rate on 27 July 2000 being the rate applicable at the time of the issue of the Senior Bonds. The actual exchange rate used will be that as at a reference date prior to the Restructuring. The termination value of hedge contracts is subject to market prices and may therefore increase or decrease from the estimate included in this document. 7 This is the aggregate amount of the TXU Claim (net of VAT payable in respect thereof). There is no assurance that the full amount of the TXU Claim will ultimately be recovered or that the AES Drax Companies will have tax losses to offset against any attributable income. 14 ----------------------- ------------------------ -------------- --------------- FINAL DEBT STERLING EQUIVALENT MATURITY INTEREST RATE ----------------------- ------------------------ -------------- --------------- Equity 100% ownership (indirect) of Drax Power Station ----------------------- ------------------------ -------------- --------------- Trading Guarantee Up to(pound)100 Facility million(8) ----------------------- ------------------------ -------------- --------------- Interest Rate Hedging(9) ----------------------- ------------------------ -------------- --------------- 1.2.2 RIGHT TO RECEIVE PRO RATA SHARE OF RESTRUCTURED DEBT One overriding principle in the Restructuring is that for each (pound)1 of senior secured indebtedness owed to a Senior Creditor such Senior Creditor will be entitled to the same participating interest in each of the tranches of debt. Accordingly, each Senior Bank, Senior Bondholder and Hedging Bank (to the extent their hedging agreement is terminated) will be allocated, in proportion to its current relative holdings of the Bank Loans, Senior Bonds or rights to Hedge Termination Payments, as the case may be: (i) participations in A-1 Debt and B Debt; and (ii) the right to receive a combination of: (a) participations in A-2 Debt and A-3 Debt (together with the A-1 Debt and B Debt, the "RESTRUCTURED Debt"); and/or (b) cash pursuant to the exercise by such Senior Creditor of its Cash-Out Option described in section 1.3 - The Cash-Out Option below. 1.2.3 SENIOR CREDITORS' RIGHT TO ALL EQUITY The Senior Creditors will, under the terms of this Restructuring proposal, have the right to become indirect owners of the whole of the equity of Drax Power in proportion to their holdings of A-3 Debt after the exercise of the Cash-Out Option. See section 1.4 - Drax Power Station Ownership. The BHP Billiton Offer does not provide for any consideration to be provided to AES or the AES Drax Energy Limited bondholders. - ------------- 8 To be finalised following agreement of a revised electricity trading policy for the AES Drax Companies. In addition, it is intended that at completion of the Restructuring a cash balance of up to (pound)50,000,000 will be available from existing Company cash resources to Drax Power for working capital purposes, subject to the cashflow cycle. 9 Discussions required between the Hedging Banks, the Senior Creditors Committees and BHP Billiton as to the treatment of hedge positions in the Restructuring. 15 1.2.4 RESTRUCTURED TRANCHES OF DEBT The Restructured Debt has been separated into tranches in order to provide for: (i) a first ranking tranche of debt(10), the A-1 Debt, of (pound)400 million with the following scheduled amortisation profile and a final maturity date of 2015: - ------------------------- --------------------------------- AMORTISATION ((POUNDS YEAR STERLING) MILLION)(11) - ------------------------- --------------------------------- 2007 10 - ------------------------- --------------------------------- 2008 20 - ------------------------- --------------------------------- 2009 55 - ------------------------- --------------------------------- 2010 55 - ------------------------- --------------------------------- 2011 55 - ------------------------- --------------------------------- 2012 55 - ------------------------- --------------------------------- 2013 50 - ------------------------- --------------------------------- 2014 50 - ------------------------- --------------------------------- 2015 50 - ------------------------- --------------------------------- Interest on A-1 Debt will be payable on a semi-annual basis. A-1 Debt will have the benefit of certain prepayment rights as well as a Debt Service Reserve Account (as defined in section 2.1.1) funded at completion of the Restructuring to an amount equal to the interest payments falling due on the two interest payment dates following the Restructuring and, thereafter, funded in accordance with the Cash Flow Waterfall (as described in section 2.2 - Cash Flow Waterfall) to a level equal to the interest and scheduled principal payments on the A-1 Debt falling due on the two interest payment dates following the relevant interest payment date; (ii) a second ranking tranche, the A-2 Debt, of up to (pound)460 million which will have no fixed amortisation profile, however, the outstanding principal balance will fall due for payment in 2015. Interest on the A-2 Debt will be payable on a semi-annual basis after payment of interest on the A-1 Debt, any hedging specific to the A-1 Debt(12) scheduled principal payments on the A-1 Debt, and a cash sweep into the Debt Service Reserve Account to ensure a required balance equal to 12 months' interest payments on A-1 Debt; A-2 Debt will also benefit from a 1.0 x look-forward test/reserve of at least six months. If there are insufficient funds to pay interest on the A-2 Debt, - ------------- 10 This is subject to the priority of the Trading Guarantee Facility (see section 1.5 - Electricity Trading Support for BHP Billiton's proposal). 11 Each annual scheduled amortisation shown above will be payable in two equal instalments on the semi-annual interest payment dates in each such year, provided that there will only be one payment in 2015. 12 Structure of hedging and ranking in Cash Flow Waterfall to be discussed with the Hedging Banks and Senior Creditors Committees. 16 interest will be deferred . Repayment of the principal on the A-2 Debt will not occur prior to the principal amount of the A-1 Debt reducing to below (pound)200 million and will, thereafter, be dependent upon there being sufficient funds available for such purpose in accordance with the Cash Flow Waterfall; (iii) a third ranking tranche, the A-3 Debt, of up to (pound)135.455 million. Unpaid interest on the A-3 Debt will be deferred (but not capitalised). The A-3 Debt will not receive cash payments of deferred interest or principal until the A-1 Debt and A-2 Debt have been repaid in full; (iv) a fourth ranking tranche, the B Debt, of(pound)338.4 million whose primary source of repayment will be payments received in relation to the TXU Claim and will have first ranking security over the TXU Claim. The B Debt will also have security over the Principal Drax Assets ranking junior to the A-3 Debt. Interest will accrue on the B Debt and will be paid in accordance with the Cash Flow Waterfall, where it ranks behind scheduled A-1 Debt payments, A-2 Debt and A-3 Debt interest payments and, inter alia, deposits to a debt service reserve account to ensure a required balance equal to 12 months' interest and scheduled principal payments on the A-1 Debt. If there are insufficient funds to pay interest on the B Debt, interest will be deferred, but not capitalised. Proceeds of the TXU Claim will be used to repay the principal amount of the B Debt and interest thereon. The principal amount outstanding of the B Debt will only otherwise be repaid once the A-1 Debt, the A-2 Debt and the A-3 Debt have been repaid in full. See section 2.2 - Cash Flow Waterfall for further details. All Restructured Debt will accrue interest as from 1 July 2003 (see section 1.3.5 - Accrual of Interest). 1.3 THE CASH-OUT OPTION 1.3.1 OPTION TO SELL A-2 DEBT AND A-3 DEBT As part of the Restructuring, each Senior Creditor will have the option (the "CASH-OUT OPTION") to sell, at a discount (see section 1.3.2. below), all of its participation in the A-2 Debt and the A-3 Debt, provided that a Senior Creditor may tender on a pro-rata basis part of its A-2 Debt and A-3 Debt. Any such sales will be completed concurrently with the issuance of the Restructured Debt. A Senior Creditor that exercises its Cash-Out Option will forego any right to receive Equity (as defined in section 1.4.1 - Ownership below) for any A-3 Debt sold in the Cash-Out Option. The Cash-Out Option is designed to provide Senior Creditors with an alternative in order to realise immediate cash value for the holding of A-2 Debt, A-3 Debt and Equity which would otherwise be allocated to them. 1.3.2 DISCOUNT PRICE Under the Cash-Out Option, the discount price for a Senior Creditor's participation in A-3 Debt will be 1% of its original principal amount. The discount price for a 17 Senior Creditor's participation in A-2 Debt will be 70% of its original principal amount. 1.3.3 SOURCE OF FUNDS Two sources of funds will be available to make payments to Senior Creditors who elect to accept the Cash-Out Option ("CASH-OUT FUNDS"): (i) the amount, being at a minimum (pound)30,000,000, which will be available to the AES Drax Companies (after taking into account fees and expenses in connection with the Restructuring and working capital requirements subject to the cashflow cycle) is that amount of cash (the "PROJECT FUNDS") in excess of funds required to make payment in full of amounts in the Cash Flow Waterfall down to and including A-2 Debt interest on 31 December, 2003 and, therefore, is yet to be finally determined; and (ii) up to (pound)95,000,000 (or such greater amount as is referred to below) is to be made available by BHP Billiton or one of its affiliates (the "BHP BILLITON FUNDS"). The Cash-Out Funds for the Cash-Out Option will be made available as follows: (i) first, by the AES Drax Companies from Project Funds up to(pound)30,000,000; (ii) second, the amount of incremental Project Funds in excess of the (pound)30,000,000 that the Company and Senior Creditors elect to use until all Project Funds are exhausted; and (iii) finally, any additional amounts that are required will be funded from BHP Billiton Funds until BHP Billiton Funds are exhausted. It is possible that the amount of BHP Billiton Funds might be increased if the Cash-Out Option is taken up by Senior Creditors in such a manner that the (pound)95,000,000 would prove to be insufficient. If demand for the Cash-Out Option is so strong that additional funds are required, BHP Billiton reserves the right to increase the amount of the BHP Billiton Funds and, if necessary, will endeavour to obtain additional funding from third parties. If Cash-Out Funds are insufficient to make payments in full to all the Secured Creditors who elect to accept the Cash-Out Option (each an "ELECTING SECURED CREDITOR") then each Electing Secured Creditor will be "scaled back". All Cash-Out Funds will be used so that each Electing Secured Creditor will sell its A-2 Debt and A-3 Debt pro rata to its claim as a Secured Creditor relative to the aggregate of claims of all Electing Secured Creditors. Each Electing Secured Creditor will then receive A-2 Debt and A-3 Debt which remains unsold under its exercise of the Cash-Out Option and, therefore, a corresponding portion of the Equity. 1.3.4 CONSEQUENCES OF CASH-OUT OPTION To the extent that Project Funds are used to purchase participations in A-2 Debt and A-3 Debt under the Cash-Out Option, the outstanding amount of such debt will be retired, thereby deleveraging the Drax project. To the extent that BHP Billiton purchases participations in A-2 Debt and A-3 Debt, it will become a Senior Creditor 18 holding Restructured Debt. In addition, BHP Billiton will have the option to receive Equity in proportion to the amount of A-3 Debt it purchases. 1.3.5 ACCRUAL OF INTEREST No interest will be paid in respect of the debt to be compromised in the Restructuring which is held by the Senior Banks and the holders of the Senior Bonds for the period from and including 1 July 2003 to the completion of the Restructuring. However, interest will accrue in respect of the Restructured Debt as from 1 July 2003 as if such debt had been issued on such date, and will be paid in accordance with the Cash Flow Waterfall. Appropriate treatment will need to be agreed in relation to those Senior Creditors who exercise the Cash-Out Option. 1.4 DRAX POWER STATION OWNERSHIP 1.4.1 OWNERSHIP The indirect ownership of the Drax power station will be transferred to the holders of the A-3 Debt in the form of all of the shares (the "EQUITY") in a holding company (the "PARENT") which indirectly owns all of the equity in Drax Power. As indicated under section 1.3 - The Cash-Out Option above, if a Senior Creditor exercises the Cash-Out Option, then it will not receive any Equity for any A-3 Debt sold under the Cash-Out Option. In addition: (i) to the extent that the Cash-Out Option is funded by Project Funds, Equity corresponding to A-3 Debt that is prepaid will not be issued; and (ii) to the extent that the Cash-Out Option is funded by BHP Billiton Funds, BHP Billiton will have the option, at no additional cost, to become the owner of the Equity corresponding to the A-3 Debt purchased by BHP Billiton. 1.4.2 RESTRICTIONS ON TRADING In order to provide a period of stability following the Restructuring within which the Drax power station may operate, the A-2 Debt, A-3 Debt and Equity (including any option to hold Equity) (together, the "LINKED SECURITIES") will remain "linked" for an initial period13. During this period, no holder of Linked Securities may sell any single Linked Security without also selling proportionate amounts of its other Linked Securities. 1.5 ELECTRICITY TRADING SUPPORT As mentioned in paragraph 5 of the BHP Billiton Offer Letter, Drax Power will require substantial credit support to continue its electricity trading activities following the Restructuring. If Drax Power is no longer required to provide cash collateral as credit support this will enhance the liquidity of the Drax power station and provide cash for other purposes, including working capital and funding the Cash-Out Option. BHP Billiton is willing to arrange from closing of the Restructuring, subject to agreement of satisfactory terms by 30 September 2003 and internal BHP Billiton credit approval, a (pound)100,000,000 Trading 19 Guarantee Facility to facilitate Drax Power's ability to trade electricity. A portion of this Trading Guarantee Facility may take the form of credit lines with a BHP Billiton entity. Facility utilisation fees shall be calculated based on the aggregate risk exposures generated by Drax Power's trading activities, providing a more efficient facility than traditional credit facilities. This Facility shall, at all times, have first ranking security interest (senior to the Senior Creditors) over the Principal Drax Assets. 2 SECTION 2 - DETAILED TERMS OF THE RESTRUCTURING PROPOSAL 2.1 RESTRUCTURED DEBT 2.1.1 A-1 DEBT (PRINCIPAL AMOUNT: (POUND)400 MILLION): RANKING: A-1 Debt will have the benefit of a second ranking security interest over all of the properties, assets and shares of the AES Drax Companies (other than recoveries on the TXU Claim which will be subject to a first ranking security interest for the benefit of the B Debt) (such properties, assets and shares other than the TXU Claim, the "PRINCIPAL DRAX ASSETS"). A-1 Debt has a second ranking security interest over the Principal Drax Assets solely because it ranks after the security interest in respect of the Trading Guarantee Facility (up to(pound)100 million). Otherwise, A-1 Debt has a security interest that ranks ahead of all other tranches of the Restructured Debt INTEREST RATE: Libor plus a margin of 2.5%. INTEREST PAYMENT Semi - annual. DATE: FINAL MATURITY 30 June 2015 DATE: AMORTISATION: Scheduled amortisation to be paid in each year in equal instalments on semi-annual interest payment dates and on the Final Maturity Date as follows: 2007: (pound)10 million 2008: (pound)20 million 2009: (pound)55 million 2010: (pound)55 million 2011: (pound)55 million 2012: (pound)55 million 2013: (pound)50 million 2014: (pound)50 million 20 2015: (pound)50 million PREPAYMENT: Until the principal amount of the A-1 Debt has reduced below (pound)200,000,000, cash available for debt service will, after payment of A-1 Debt interest and hedging, A-1 Debt scheduled amortisation, funding the DSRA (defined below) for 12 months' A-1 Debt interest and scheduled principal, payment of A-2 Debt interest (including deferred interest and, if applicable, funding the A-2 Debt Interest Reserve) and interest on the A-3 Debt and B Debt be applied solely to prepayment of A-1 Debt principal in inverse order of the scheduled amortisation profile. At any time after the principal amount of the A-1 Debt has reduced below (pound)200m, excess cash available for debt service will, after payment of the amounts referred to in the immediately preceding paragraph, be applied on a pro rata basis to (a) prepayment of A-1 Debt principal, in inverse order of the scheduled amortisation profile, and (b) A-2 Debt principal, (for the avoidance of doubt, this means proportionally to the outstanding amount of A-1 Debt and A-2 Debt immediately prior to the prepayments). PRIORITY OF See section 2.2 - Cash Flow PAYMENTS: Waterfall. DEBT SERVICE A debt service reserve account (the RESERVE ACCOUNT: "DEBT SERVICE RESERVE ACCOUNT" or "DSRA") will be established immediately on the completion of the Restructuring from funds available in the Drax project in an amount equal to the interest falling due on the A-1 Debt on the next two interest payment dates. Following the Restructuring, after payment of A-1 Debt interest and hedging and scheduled A-1 Debt amortisation, cash available for debt service will be transferred to the DSRA to the extent required to ensure that the required balance thereon is equal to the next two A-1 Debt interest payments. In addition, after payment of A-2 Debt interest (including deferred interest and, if applicable, funding the A-2 Debt Interest Reserve), cash available for debt service of up to the amount of scheduled A-1 Debt amortisation falling due on the next two interest payment dates will be transferred to the DSRA. To the extent that the funds credited to the DSRA as of an A-1 Debt interest payment date exceed the required DSRA balance determined as of such date, the excess may be withdrawn and used to make payments in 21 accordance with the Cash Flow Waterfall. COVENANT PACKAGE: The covenant package is to be negotiated, but is expected to have the level of protections similar to those in the current Bank Loans. ACCELERATION AND To be discussed with the Senior ENFORCEMENT: Creditors Committees on the basis of the proposal set out in the 30 June 6K. CHANGE OF To be discussed with the Senior CONTROL: Creditors Committees on the basis of the proposal set out in the 30 June 6K. CREDIT RATING: To be discussed with the Senior Creditors Committees. 2.1.2 A-2 DEBT (PRINCIPAL AMOUNT: UP TO (POUND)460 MILLION): RANKING: A-2 Debt will have the benefit of a third ranking security interest over the Principal Drax Assets, ranking in point of security after the amounts owing under the Trading Guarantee Facility and the A-1 Debt. INTEREST RATE: Libor plus a margin of 4%. INTEREST PAYMENT: Interest on the A-2 Debt will be payable on a semi-annual basis after payment of interest on the A-1 Debt and hedging, scheduled principal payments on the A-1 Debt, and a cash sweep into the Debt Service Reserve Account to ensure a required balance equal to 12 months interest payments on A-1 Debt. Unpaid interest is deferred (not capitalised) and bears interest at the same rate. A-2 DEBT INTEREST There will be a six month (18 RESERVE: months on or before 31 December 2006) look-forward test for A-2 Debt interest on a 1.0 x debt service cover ratio, and to the extent such test is not passed, an amount equal to the shortfall will (in accordance with the Cash Flow Waterfall) be placed in a reserve account (the "A2 DEBT INTEREST RESERVE"). Amounts standing to the credit of the A-2 Debt Interest Reserve would be used to make payments of interest and scheduled principal on the A-1 Debt before making payments of interest on the A-2 Debt if there were insufficient funds available in the Cash Flow Waterfall for such purpose and if the DSRA had been fully utilised. FINAL MATURITY 30 June 2015. DATE: AMORTISATION: No scheduled amortisation of principal. Once the principal amount outstanding of A-1 Debt is less than(pound)200 million, excess cash available for debt service will, after payment of the A-1 Debt interest and hedging, 22 scheduled A-1 Debt principal amortisation, funding the DSRA for 12 months' A-1 Debt interest, payment of A-2 Debt interest (including deferred interest and, if applicable, funding the A-2 Debt Interest Reserve) and interest on the A-3 Debt and B Debt and hedging, funding the DSRA for 12 months' A-1 debt scheduled principal, be applied to prepayment of A-1 Debt principal and A-2 Debt principal on a pro rata basis.

To the extent so exercised and to the extent the purchase is funded from Project Funds, the A-2 Debt so purchased will be cancelled. For further details, see section 1.3 - The Cash-Out Option above. CHANGE OF To be discussed with the Senior CONTROL: Creditors Committees on the basis of the proposal set out in the 30 June 6K. 2.1.3 A-3 DEBT: PRINCIPAL AMOUNT: UP TO (POUND)135.455 MILLION RANKING: A-3 Debt will have the benefit of a fourth ranking security interest over the Principal Drax Assets. INITIAL PRINCIPAL The initial principal amount of the AMOUNT A-3 Debt will, subject to reduction in accordance with the Cash-Out Option, be the difference between: (i) the aggregate amount of the Senior Creditors' indebtedness being ' compromised by the Restructuring; and (ii) the aggregate amount of the A-1 Debt, A-2 Debt and B Debt (before any reduction of any amount in respect of Senior Creditors exercising the Cash-out Option). INTEREST RATE: Libor plus a margin of 5%. INTEREST PAYMENT Interest on A-3 Debt shall be DATE: deferred (but not capitalised) if there are insufficient funds available in the Cash Flow Waterfall for such purpose.

Amounts standing to the credit of the A-3 Debt Interest Reserve would be used to make payments of interest and scheduled principal on the A-1 Debt or the A-2 Debt before making payments of interest on the A-3 Debt if there are insufficient funds available in the Cash Flow Waterfall for such purpose. AMORTISATION: A-3 Debt principal will only be paid after all of the A-1 Debt and A-2 Debt have been paid in full. COVENANT PACKAGE: Limited covenant package to be agreed. ACCELERATION AND To be discussed with the Senior ENFORCEMENT: Creditors Committees on the basis of the proposal set out in the 30 June 6K.

B Debt will have a first ranking security interest over the TXU Claim proceeds. The B Debt will have a fifth ranking security interest over the Principal Drax Assets. To the extent the proceeds of the TXU Claim are insufficient to repay the B Debt (and deferred interest thereon), payment of such remaining B Debt will be made in accordance with the Cash Flow Waterfall (see section 2.2 - Cash Flow Waterfall below). INTEREST RATE: Libor plus a margin of 2%. INTEREST PAYMENT: B Debt interest will be deferred (but not capitalised) to the extent excess cash is not available after payment of 24 interest on the A-1 Debt and hedging, scheduled principal payments on the A-1 Debt, funding the DSRA for 12 months' A-1 Debt interest and scheduled principal and payment of A-2 Debt interest (including deferred interest and, if applicable, funding the A-2 Debt Interest Reserve) and hedging and payment of A-3 Debt interest (including deferred interest and, if applicable, funding the A-3 Debt Interest Reserve) (see section 2.2 - Cash Flow Waterfall below).
