Euro 10,000,000,000
Euro Medium Term Note Programme

In respect of Instruments to be issued by National Grid Gas Finance (No 1) plc, unconditionally
and irrevocably guaranteed by

NATIONAL GRID GAS plc

Under the Euro Medium Term Note Programme (the “Programme”) described in this Prospectus (the “Prospectus”), each of National Grid Gas plc (“National Grid Gas”) and National Grid Gas Finance (No 1) plc (“National Grid Gas Finance (No 1)”) (each, an “Issuer” and together, the “Issuers”) subject to compliance with all relevant laws, regulations and directives, may from time to time issue debt instruments (the “Instruments”) denominated in any currency agreed between the relevant Issuer, the Trustee and the relevant Dealer (as defined below). Instruments issued by National Grid Gas Finance (No 1) plc will be guaranteed by National Grid Gas (in such capacity, the “Guarantor”). The aggregate nominal amount of Instruments outstanding will not at any time exceed euro 10,000,000,000 (or the equivalent in other currencies). The Instruments will only be issued in bearer form.

Application has been made to the Financial Services Authority in its capacity as competent authority (the “UK Listing Authority”) under the Financial Services and Markets Act 2000 (“FSMA”) for Instruments issued under the Programme for the period of 12 months from the date of this Prospectus to be admitted to the official list of the UK Listing Authority (the “Official List”) and to the London Stock Exchange plc (the “London Stock Exchange”) for such Instruments to be admitted to trading on the London Stock Exchange’s Regulated Market (the “Market”). References in this Prospectus to Instruments being “listed” (and all related references) shall mean that such Instruments have been admitted to trading on the Market and have been admitted to the Official List. The Market is a regulated market for the purposes of Directive 2004/39/EC of the European Parliament and of the Council on markets in financial instruments. The Programme also permits Instruments to be issued on an unlisted basis or to be admitted to listing, trading and/or quotation by such other or further listing authorities, stock exchanges and/ or quotation systems as may be agreed with the relevant Issuer. The relevant Final Terms (as defined on page 9) in respect of the issue of any Instruments will specify whether or not such Instruments will be listed on the Official List and admitted to trading on the Market (or any other listing authority, stock exchange and/or quotation system).

Each Series (as defined on page 8) of Instruments will be represented on issue by a temporary global instrument in bearer form (each a “temporary Global Instrument”) or a permanent global instrument (each a “permanent Global Instrument”). If the Global Instruments are stated in the applicable Final Terms to be issued in new global note (“NGN”) form they are intended to be eligible collateral for Eurosystem monetary policy and the Global Instruments will be delivered on or prior to the original issue date of the relevant Tranche to a common safekeeper (the “Common Safekeeper”) for Euroclear Bank S.A./N.V. (“Euroclear”) and Clearstream Banking,société anonyme(“Clearstream, Luxembourg”). Global notes which are not issued in NGN form (“Classic Global Notes” or “CGNs”) will be deposited on the issue date of the relevant Tranche with a common depositary on behalf of Euroclear and Clearstream, Luxembourg (the “Common Depositary”). The provisions governing the exchange of interests in any Global Instruments for interests in any other Global Instruments and Definitive Instruments are described in “Summary of Provisions Relating to the Instruments while in Global Form”.

Tranches of Instruments (as defined in “Overview of the Programme”) may be rated or unrated. Where a Tranche of Instruments is rated, such rating will be specified in the relevant Final Terms. A rating is not a recommendation to buy, sell or hold securities and may be subject to suspension, reduction or withdrawal at any time by the assigning rating agency.

In the case of any Instruments which are to be admitted to trading on a regulated market within the European Economic Area or offered to the public in a Member State of the European Economic Area in circumstances which require the publication of a prospectus under the relevant Directive 2003/71/EC (the “Prospectus Directive”), the minimum specified denomination shall be€50,000 (or its equivalent in any other currency as at the date of issue of the relevant Instruments).

Prospective investors should have regard to the factors described under the section headed “Risk Factors” in this Prospectus.

Early Redemption	Except as provided in “Optional Redemption” above and subject always to the regulations and any other laws, regulations and directives applicable to the relevant currency in which such Instruments are denominated, Instruments will be redeemable at the option of the relevant Issuer prior to maturity only for tax reasons. See “Terms and Conditions of the Instruments - Redemption, Purchase and Options”.
Withholding Tax	All payments of principal and interest in respect of the Instruments will be made free and clear of withholding taxes of the United Kingdom save as compelled by law.

Ratings	Tranches of Instruments may be rated or unrated. Where a Tranche of Instruments is rated, such rating will be specified in the relevant Final Terms.

	Category 2 selling restrictions will apply to the Instruments for the purposes of Regulation S under the Securities Act.
	The Instruments will be issued in compliance with U.S. Treas. Reg. §1.163-5(c)(2)(i)(D) (the “D Rules”) unless (a) the relevant Final Terms states that Instruments are issued in compliance with U.S. Treas. Reg. §1.163-5(c)(2)(i)(C) (the “C Rules”) or (b) the Instruments are issued other than in compliance with the D Rules or the C Rules but in circumstances in which the Instruments will not constitute “registration required obligations” under the United States Tax Equity and Fiscal Responsibility Act of 1982 (“TEFRA”),

12

which circumstances will be referred to in the relevant Final Terms as a transaction to which TEFRA is not applicable.

Terms and Conditions

The Terms and Conditions applicable to each Series will be as agreed between the relevant Issuer, the Guarantor (where applicable), the Trustee and the relevant Dealer(s) or other purchaser at or prior to the time of issuance of such Series and will be specified in the relevant Final Terms.

RISK FACTORS

The relevant Issuer and the Guarantor believe that the following factors may affect their ability to fulfil their obligations under Instruments issued under the Programme. All of these factors are contingencies which may or may not occur and the relevant Issuer and the Guarantor are not in a position to express a view on the likelihood of any such contingency occurring.

Factors which the relevant Issuer and the Guarantor believe may be material for the purpose of assessing the market risks associated with Instruments issued under the Programme are also described below.

The relevant Issuer and the Guarantor believe that the factors described below represent the principal risks inherent in investing in Instruments issued under the Programme, but the relevant Issuer or the Guarantor may be unable to pay interest, principal or other amounts on or in connection with any Instruments for other reasons and such Issuer and the Guarantor do not represent that the statements below regarding the risks of holding any Instruments are exhaustive. Prospective investors should also read the detailed information set out elsewhere in this Prospectus (including any documents deemed to be incorporated by reference herein) and reach their own views prior to making any investment decision.

Risks relating to National Grid Gas plc and its business

Changes in law or regulation could have an adverse effect on National Grid Gas’s results of operations

National Grid Gas is subject to regulation by governmental and regulatory authorities. Consequently, changes in law or regulation could adversely affect National Grid Gas. Changes to market structures implemented as a result of legislative developments and regulatory decisions concerning, for example, whether licences or approvals to operate are granted or renewed, whether market developments have been satisfactorily implemented, whether there has been any breach of the terms of a licence or approval, the level of permitted revenues for National Grid Gas’s businesses and proposed business development activities could have an adverse impact on National Grid Gas’s results of operations, cash flows, the financial condition of its businesses and the ability to develop those businesses in the future.

Breaches of or changes in environmental or health and safety laws or regulations could expose National Grid Gas to claims for financial compensation and adverse regulatory consequences and could damage National Grid Gas’s reputation

Aspects of National Grid Gas’s activities are potentially dangerous, such as the transmission and distribution of natural gas. Gas utilities also typically use and generate in their operations hazardous and potentially hazardous products and by-products. In addition, there may be other aspects of National Grid Gas’s operations that are not currently regarded as having adverse effects that could become so. National Grid Gas is subject to laws and regulations relating to pollution, the protection of the environment, and how National Grid Gas uses and disposes of hazardous substances and waste materials. National Grid Gas is also subject to laws and regulations governing health and safety matters, protecting both the public and its employees. Any breach of these obligations, or even incidents relating to the environment or to health and safety that do not amount to a breach, could adversely affect the results of operations and National Grid Gas’s reputation.

Network failure or the inability to carry out critical non-network operations may have significant adverse impacts on both National Grid Gas’s financial position and its reputation

National Grid Gas may suffer a major network failure or may not be able to carry out critical non-network operations. Operational performance could be adversely affected by a failure to maintain the health of the system or network, inadequate forecasting of demand or inadequate record keeping. This could cause National Grid Gas to be in breach of a licence or approval, and even incidents that do not amount to a breach could result in adverse regulatory action and financial consequences, as well as harming National Grid Gas’s reputation. In addition to these risks, National Grid Gas is subject to other risks that

14

are largely outside of its control such as the impact of weather or unlawful acts of third parties. Weather conditions can affect financial performance and severe weather that causes outages or damages infrastructure will adversely affect operational, and, potentially, business performance. Terrorist attack, sabotage or other intentional acts may also physically damage National Grid Gas’s businesses or otherwise significantly affect corporate activities and as a consequence affect the results of operations.

National Grid Gas’s results of operations depend on a number of factors relating to business performance including performance against regulatory targets and the delivery of anticipated costs and efficiency savings

Earnings maintenance and growth from National Grid Gas’s regulated gas business may be affected by its ability to meet or better efficiency targets and/or incentives set by Ofgem. Earnings from National Grid Gas’s regulated businesses will also be affected by its ability to recover incurred expenditure. Levels of earnings from National Grid Gas’s businesses may also be affected by failure to meet service quality standards set by Ofgem. National Grid Gas is also reorganising its operations along lines of business. In addition, from time to time National Grid Gas publishes cost and efficiency savings targets for its businesses. To meet these targets and standards, National Grid Gas must improve operational performance, service reliability and customer service. If National Grid Gas does not meet these targets and standards, if it is not able to recover incurred expenditure or if it does not implement this reorganisation as envisaged, it may not achieve the expected benefits, its business may be adversely affected and its performance, results of its operations and reputation may be harmed.

Changes to the regulatory treatment of commodity costs may have an adverse effect on the results of operations

Changes in commodity prices could potentially impact on National Grid Gas’s energy delivery businesses. Current regulatory arrangements in the UK provide the ability to pass through virtually all of the increased costs related to commodity prices to consumers. If Ofgem were to restrict this ability, it could have an adverse effect on National Grid Gas’s operating results.

National Grid Gas’s reputation may be harmed if consumers of energy suffer a disruption to their supply even if this disruption is outside of National Grid Gas’s control

National Grid Gas is responsible for transporting available gas. National Grid Gas consults with and provides information to Ofgem and the UK Government and industry participants about future demand and the availability of supply. However, where there is insufficient supply to meet demand, whether because of extreme weather conditions, or failure of plant or systems operated by either National Grid Gas or third parties, National Grid Gas’s role is to manage the relevant system safely, which, in extreme circumstances, may require National Grid Gas to disconnect consumers.

National Grid Gas is subject to the risk that business development activity, such as significant acquisitions or disposals, will be based on incorrect assumptions or conclusions or that significant liabilities will be overlooked or there may be other unanticipated adverse impacts

In any acquisition or disposal process National Grid Gas evaluates the projected financial impact of the transaction and conducts appropriate due diligence. Despite National Grid Gas’s efforts, however, unforeseen circumstances or erroneous assumptions may adversely affect the anticipated financial consequences of a project.

The nature and extent of National Grid Gas’s borrowings means that an increase in interest rates could have an adverse impact on its financial position and business results

A significant proportion of National Grid Gas’s borrowings are subject to variable interest rates that may fluctuate with changes to prevailing interest rates. Increases in these interest rates could therefore increase National Grid Gas’s costs and diminish its profits.

National Grid Gas’s overall financial position may be adversely affected by a number of factors including restrictions in borrowing and debt arrangements, changes to credit ratings and effective tax rates

15

National Grid Gas is subject to certain covenants and restrictions in relation to its listed debt securities and its bank lending facilities. National Grid Gas is also subject to restrictions on financing that have been imposed by regulators. These restrictions may hinder National Grid Gas in servicing the financial requirements of its businesses. The debt issued by National Grid Gas is rated by credit rating agencies and changes to these ratings may affect both the borrowing capacity of the National Grid Gas Group as a whole and the cost of these borrowings. The effective rate of tax paid by the National Grid Gas Group may be influenced by a number of factors including changes in law and accounting standards.

Future funding requirements of National Grid’s pension schemes could adversely affect National Grid Gas’s results of operations

National Grid Gas participates in a of pension scheme which covers the majority of its employees. This scheme is a defined benefit scheme where the scheme assets are held independently of National Grid Gas’s finances. Estimates of the amount and timing of future funding for this scheme are based on various actuarial assumptions and other factors including, among other things, the actual and projected market performance of the scheme assets, future long-term bond yields, average life expectancies and relevant legal requirements. The impact of these assumptions and other factors may require National Grid Gas to make additional contributions to this pension scheme which, to the extent they are not recoverable under its price controls, could adversely affect results of operations of National Grid Gas.

New or revised accounting standards, rules and interpretations by the UK, or international accounting standard setting boards and other relevant bodies could have an adverse effect on National Grid Gas’s reported financial results

The accounting treatment under International Financial Reporting Standards (“IFRS”), as adopted by the European of replacement expenditure, pension and post-retirement benefits, derivative financial instruments and commodity contracts significantly affect the way National Grid Gas reports its financial position and results of operations. As a body of practice develops for IFRS, the application and interpretation of accounting principles to National Grid Gas’s circumstances, and to those areas in particular, could result in changes in the financial results and financial position that it reports. In addition new standards, rules or interpretations may be issued that could also have significant effects.

Risk relating to National Grid Gas Finance (No 1) plc and its business

National Grid Gas Finance (No 1)’s only business is to act as a finance subsidiary of National Grid Gas and it has no assets other than the amounts representing the proceeds of its issued and paid-up share capital, such fees (if any) payable to it in connection with the issue of Instruments or entry into other obligations from time to time and any on-loan made by it of the proceeds of the issue of any Instruments.

Factors which are material for the purpose of assessing the market risks associated with Instruments issued under the Programme

Instruments may not be a suitable investment for all investors

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

(i)	have sufficient knowledge and experience to make a meaningful evaluation of the relevant Instruments, the merits and risks of investing in the relevant Instruments and the information contained or incorporated by reference in this Prospectus or any applicable supplement;
(ii)	have access to, and knowledge of, appropriate analytical tools to evaluate, in the context of its particular financial situation, an investment in the relevant Instruments and the impact such investment will have on its overall investment portfolio;
(iii)	have sufficient financial resources and liquidity to bear all of the risks of an investment in the relevant Instruments, including where principal or interest is payable in one or more currencies, or

16

	where the currency for principal or interest payments is different from the potential investor’s currency;
(iv)	understand thoroughly the terms of the relevant Instruments and be familiar with the behaviour of any relevant indices and financial markets; and
(v)	be able to evaluate (either alone or with the help of a financial adviser) possible scenarios for economic, interest rate and other factors that may affect its investment and its ability to bear the applicable risks.

Some Instruments are complex financial instruments and such instruments may be purchased as a way to reduce risk or enhance yield with an understood, measured, appropriate addition of risk to their overall portfolios. A potential investor should not invest in Instruments which are complex financial instruments unless it has the expertise (either alone or with the help of a financial adviser) to evaluate how the Instruments will perform under changing conditions, the resulting effects on the value of such Instruments and the impact this investment will have on the potential investor’s overall investment portfolio.

Risks related to the structure of a particular issue of Instruments

A wide range of Instruments may be issued under the Programme. A number of these Instruments may have features which contain particular risks for potential investors. Set out below is a description of certain such features:

Instruments subject to optional redemption by the Issuer

An optional redemption feature is likely to limit the market value of Instruments. During any period when the Issuer may elect to redeem Instruments, the market value of those Instruments generally will not rise substantially above the price at which they can be redeemed. This also may be true prior to any redemption period.

The Issuer may be expected to redeem Instruments when its cost of borrowing is lower than the interest rate on the Instruments. At those times, an investor generally would not be able to reinvest the redemption proceeds at an effective interest rate as high as the interest rate on the Instruments being redeemed and may only be able to do so at a significantly lower rate. Potential investors should consider reinvestment risk in light of other investments available at that time.

Index Linked Instruments and Dual Currency Instruments

The Issuer may issue Instruments with principal or interest determined by reference to an index or formula, to changes in the prices of securities or commodities, to movements in currency exchange rates or other factors (each, a “Relevant Factor”). In addition, the Issuer may issue Instruments with principal or interest payable in one or more currencies which may be different from the currency in which the Instruments are denominated. Potential investors should be aware that:

(i)	the market price of such Instruments may be volatile;
(ii)	they may receive no interest;
(iii)	payment of principal or interest may occur at a different time or in a different currency than expected;
(iv)	the amount of principal payable at redemption may be less than the nominal amount of such Instruments or even zero;
(v)	a Relevant Factor may be subject to significant fluctuations that may not correlate with changes in interest rates, currencies or other indices;
(vi)	if a Relevant Factor is applied to Instruments in conjunction with a multiplier greater than one or contains some other leverage factor, the effect of changes in the Relevant Factor on principal or interest payable likely will be magnified; and

17

(vii) the timing of changes in a Relevant Factor may affect the actual yield to investors, even if the average level is consistent with their expectations. In general, the earlier the change in the Relevant Factor, the greater the effect on yield.

Partly-paid Instruments

The Issuer may issue Instruments where the issue price is payable in more than one instalment. Failure to pay any subsequent instalment could result in an investor losing all of its investment.

Variable rate Instruments with a multiplier or other leverage factor

Instruments with variable interest rates can be volatile investments. If they are structured to include multipliers or other leverage factors, or caps or floors, or any combination of those features or other similar related features, their market values may be even more volatile than those for securities that do not include those features.

Fixed/Floating Rate Instruments

Fixed/Floating Rate Instruments may bear interest at a rate that the Issuer may elect to convert from a fixed rate to a floating rate, or from a floating rate to a fixed rate. The Issuer’s ability to convert the interest rate will affect the secondary market and the market value of such Instruments since the Issuer may be expected to convert the rate when it is likely to produce a lower overall cost of borrowing. If the Issuer converts from a fixed rate to a floating rate, the spread on the Fixed/Floating Rate Instruments may be less favourable than the prevailing spreads on comparable Floating Rate Instruments tied to the same reference rate. In addition, the new floating rate at any time may be lower than the rates on other Instruments. If the Issuer converts from a floating rate to a fixed rate, the fixed rate may be lower than the prevailing rates on its Instruments.

Instruments issued at a substantial discount or premium

The market values of securities issued at a substantial discount or premium to their nominal amount tend to fluctuate more in relation to general changes in interest rates than do prices for conventional interest-bearing securities. Generally, the longer the remaining term of the securities, the greater the price volatility as compared to conventional interest-bearing securities with comparable maturities.

Risks related to Instruments generally

Set out below is a brief description of certain risks relating to the Instruments generally:

Modification, waivers and substitution

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

The Terms and Conditions of the Instruments also provide that the Trustee may, without the consent of Instrumentholders, agree to (a) any modification of any of the provisions of the Trust Deed that is of a formal, minor or technical nature or is made to correct a manifest error, (b) any other modification (except as mentioned in the Trust Deed), and any waiver or authorisation of any breach or proposed breach, of any of the provisions of the Trust Deed that is in the opinion of the Trustee not materially prejudicial to the interests of the Instrumentholders or (c) the substitution of another company as principal debtor under any Instruments in place of the Issuer, in the circumstances described in Condition 11 of the Terms and Conditions of the Instruments.

European Monetary Union

If the United Kingdom joins the European Monetary Union prior to the maturity of the Instruments, there is no assurance that this would not adversely affect investors in the Instruments. It is possible that prior to the maturity of the Instruments the United Kingdom may become a participating Member State and that the Euro may become the lawful currency of the United Kingdom. In that event (i) all amounts payable in respect of any Instruments denominated in Sterling may become payable in Euro (ii) the law

18

may allow or require such Instruments to be re-denominated into Euro and additional measures to be taken in respect of such Instruments; and (iii) there may no longer be available published or displayed rates for deposits in Sterling used to determine the rates of interest on such Instruments or changes in the way those rates are calculated, quoted and published or displayed. The introduction of the Euro could also be accompanied by a volatile interest rate environment, which could adversely affect investors in the Instruments.

EUSavings Directive

Under the EU Council Directive 2003/48/EC on the taxation of savings income (the “EU Savings Directive”) each Member State is required to provide the tax authorities of another Member State with details of payments of interest or other similar income paid by a person within its jurisdiction to, or collected by such a person for, an individual resident or certain types of entities called “residual entities”, within the meaning of the EU Savings Directive (the “Residual Entities”), established in that other Member State; however, for a transitional period, Austria, Belgium and Luxembourg are permitted to apply an optional information reporting system whereby if a beneficial owner, within the meaning of the EU Savings Directive, does not comply with a prescribed procedure for information reporting, the relevant Member State will levy a withholding tax on payments to such beneficial owner. The withholding tax system will apply for a transitional period during which the rate of the withholding will rise over time to 35%. The transitional period is to terminate at the end of the first full fiscal year following agreement by certain non-EU countries to the exchange of information relating to such payments.

A number of non-EU countries, and certain dependent or associated territories of certain Member States, have adopted similar measures. In addition, the Member States have entered into provision of information or transitional withholding arrangements with certain of those dependent or associated territories (in relation to payments made by a person in a Member State to, or collected by such a person for, an individual resident or a Residual Entity established in one of those territories.

If, following implementation of the EU Savings Directive, a payment were to be made or collected through a Member State which has opted for a withholding system and an amount of, or in respect of tax were to be withheld from that payment, neither the Issuer nor any Paying Agent nor any other person would be obliged to pay additional amounts with respect to any note as a result of the imposition of such withholding tax. However, the Issuer is required, save as provided in Condition 6.4 of the Instruments to maintain a Paying Agent in a Member State that will not be obliged to withhold or deduct tax pursuant to the EU Savings Directive or any other Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 or any law implementing or complying with, or introduced to conform to, such directive.

Change of law

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

Integral multiples of less than Euro 50,000

In relation to any issue of Instruments which have a denomination consisting of the minimum Specified Denomination of Euro 50,000 plus a higher integral multiple of another smaller amount, it is possible that the Instruments may be traded in amounts in excess of Euro 50,000 (or its equivalent) that are not integral multiples of Euro 50,000 (or its equivalent). In such a case a holder who, as a result of trading such amounts, holds a principal amount of less than the minimum Specified Denomination will not receive a Definitive Instrument in respect of such holding (should Definitive Instruments be printed) and would need to purchase a principal amount of Instruments such that it holds an amount equal to one or

19

more Specified Denominations. Except in circumstances set out in the relevant Global Instrument, investors will not be entitled to receive Definitive Instruments.

Risks related to the market generally

Set out below is a brief description of certain market risks, including liquidity risk, exchange rate risk, interest rate risk and credit risk:

The secondary market generally

Instruments may have no established trading market when issued, and one may never develop. If a market does develop, it may not be liquid. Therefore, investors may not be able to sell their Instruments easily or at prices that will provide them with a yield comparable to similar investments that have a developed secondary market. This is particularly the case for Instruments that are especially sensitive to interest rate, currency or market risks, are designed for specific investment objectives or strategies or have been structured to meet the investment requirements of limited categories of investors. These types of Instruments generally would have a more limited secondary market and more price volatility than conventional debt securities. Illiquidity may have a severely adverse effect on the market value of Instruments.

The Clearing Systems

Because the Global Instruments may be held by or on behalf of Euroclear Bank S.A./N.V. (“Euroclear”) and Clearstream Banking,société anonyme(“Clearstream, Luxembourg”) investors will have to rely on the procedures of Euroclear and Clearstream, Luxembourg for transfer, payment and communication with the Issuer.

Instruments issued under the Programme may be represented by one or more temporary Global Instruments or permanent Global Instruments. Such Global Instruments may be deposited with a common depositary for Euroclear and Clearstream, Luxembourg. Except in the circumstances described in the relevant Global Instrument, investors will not be entitled to receive Definitive Instruments. Euroclear and Clearstream, Luxembourg will maintain records of the interests in the Global Instruments. While the Instruments are represented by one or more Global Instruments, investors will be able to trade their interests only through Euroclear or Clearstream, Luxembourg.

While Instruments are represented by one or more Global Instruments, the Issuer will discharge its payment obligations under such Instruments by making payments to the common depositary for Euroclear and Clearstream, Luxembourg for distribution to their account holders. A holder of an interest in a Global Instrument must rely on the procedures of Euroclear and Clearstream, Luxembourg to receive payments under the relevant Instruments. The Issuer has no responsibility or liability for the records relating to, or payments made in respect of, interests in the Global Instruments.

Holders of interests in the Global Instruments will not have a direct right to vote in respect of the relevant Instruments. Instead, such holders will be permitted to act only to the extent that they are enabled by Euroclear or Clearstream, Luxembourg.

Exchange rate risks and exchange controls

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

20

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

Interest rate risks

Investment in Fixed Rate Instruments involves the risk that subsequent changes in market interest rates may adversely affect the value of Fixed Rate Instruments.

Credit ratings may not reflect all risks

One or more independent credit rating agencies may assign credit ratings to an issue of Instruments. The ratings may not reflect the potential impact of all risks related to structure, market, additional factors discussed above, and other factors that may affect the value of the Instruments. A credit rating is not a recommendation to buy, sell or hold securities and may be revised or withdrawn by the rating agency at any time.

Legal investment considerations may restrict certain investments

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

All capitalised terms which are not defined in these Conditions will have the meanings given to them in the Trust Deed or Part A of the relevant Final Terms. Those definitions will be endorsed on the Definitive Instruments. References in these terms and conditions to “Instruments” are to the Instruments of one Series only of the relevant Issuer (as defined below), not to all Instruments that may be issued under the Programme. Provisions which are marked with * only apply where National Grid Gas Finance (No 1) is the Issuer.
	National Grid Gas plc (“National Grid Gas”) and National Grid Gas Finance (No 1) plc (“National Grid Gas Finance (No 1)”) (each an “Issuer” and together, the “Issuers”) and National Grid Gas plc as guarantor of Instruments issued by National Grid Gas Finance (No 1) (the “Guarantor”) have established a Euro Medium Term Note Programme (the “Programme”) for the issuance of up to Euro 10,000,000,000 in aggregate principal amount of debt instruments (the “Instruments”).
	The Instruments are constituted by an Amended and Restated Trust Deed (as amended or supplemented from time to time, the “Trust Deed”) dated 26 February 2008 between the Issuers, the Guarantor and The Law Debenture Trust Corporation p.l.c.

	Instalment Instruments are issued with one or more Receipts attached. Title to the Instruments and the Receipts, Coupons and Talons shall pass by delivery and except as ordered by a court of competent jurisdiction or as required by law, the Issuer, the Guarantor (if applicable) and the Paying Agents shall be entitled to treat the bearer of any Instrument, Receipt, Coupon or Talon as the absolute owner of that Instrument, Receipt, Coupon or Talon, as the case may be, and shall not be required to obtain any proof of ownership as to the identity of the bearer.
	In these Conditions, “Instrumentholder” means the bearer of any Instrument of one Series only of an Issuer and the Receipts relating to it, “holder” (in relation to an Instrument, Receipt, Coupon or Talon) means the bearer of any Instrument, Receipt, Coupon or Talon and capitalised terms have the meanings given to them herein, the absence of any such meaning indicating that such term is not applicable to this Instrument.
2	Status [and Guarantee]*

2.1	Status
	The Instruments and the Receipts and Coupons relating to them constitute direct, unconditional and unsecured obligations of the Issuer and rankpari passuwithout any preference or priority among themselves. The payment obligations of the Issuer under the Instruments, Receipts and Coupons [and of the Guarantor under the Guarantee]* shall, subject to such exceptions as are from time to time applicable under the laws of England, rank equally with all other present and future unsecured obligations (other than subordinated obligations, if any) of the Issuer [and the Guarantor respectively]*.
2.2	[Guarantee
	The Guarantor has unconditionally and irrevocably guaranteed the due payment of all sums expressed to be payable by the Issuer under the Trust Deed, the Instruments, Receipts and Coupons. Its obligations in that respect (the “Guarantee”) are contained in the Trust Deed.]*

3 Interest

3.1	Interest on Fixed Rate Instruments
	Each Fixed Rate Instrument bears interest on its outstanding nominal amount from the Interest Commencement Date at the rate per annum (expressed as a percentage) equal to the Rate of Interest, payable in arrear on each Interest Payment Date. The amount of interest payable shall be determined in accordance with condition 3.2.4(f).
3.2	Interest on Floating Rate Instruments and Index Linked Interest Instruments

3.2.1 Interest Payment Dates

23

	Each Floating Rate Instrument and Index Linked Interest Instrument bears interest on its outstanding nominal amount from the Interest Commencement Date at the rate per annum (expressed as a percentage) equal to the Rate of Interest, such interest being payable in arrear on each Interest Payment Date. The amount of interest payable shall be determined in accordance with condition 3.2.4(f). Such Interest Payment Date(s) is/are either specified in the relevant Final Terms as Specified Interest Payment Dates or, if no Specified Interest Payment Date(s) is/are specified in the relevant Final Terms, Interest Payment Date shall mean each date which falls the number of months or other period shown on this Instrument as the Interest Period after the preceding Interest Payment Date or, in the case of the first Interest Payment Date, after the Interest Commencement Date.
3.2.2	Business Day Convention
	If any date which is specified to be subject to adjustment in accordance with a Business Day Convention would otherwise fall on a day which is not a Business Day, then, if the Business Day Convention specified is (A) the Floating Rate Convention, such date shall be postponed to the next day which is a Business Day unless it would then fall into the next calendar month, in which event (x) such date shall be brought forward to the immediately preceding Business Day and (y) each subsequent such date shall be the last Business Day of the month in which such date would have fallen had it not been subject to adjustment, (B) the Following Business Day Convention, such date shall be postponed to the next day which is a Business Day; (C) the Modified Following Business Day Convention, such date shall be postponed to the next day which is a Business Day unless it would then fall into the next calendar month, in that event such date shall be brought forward to the immediately preceding Business Day or (D) the Preceding Business Day Convention, such date shall be brought forward to the immediately preceding Business Day.
3.2.3	Rate of Interest for Floating Rate Instruments
	The Rate of Interest in respect of Floating Rate Instruments for each Interest Accrual Period shall be determined in the manner specified in the relevant Final Terms and the provisions below relating to either ISDA Determination or Screen Rate Determination shall apply, depending upon which is specified in the relevant Final Terms.

(A)	ISDA Determination for Floating Rate Instruments: Where ISDA Determination is specified in the relevant Final Terms as the manner in which the Rate of Interest is to be determined, the Rate of Interest for each Interest Accrual Period shall be determined by the Calculation Agent as a rate equal to the relevant ISDA Rate. For the purposes of this sub-paragraph (A), “ISDA Rate” for an Interest Accrual Period means a rate equal to the Floating Rate which would be determined by the Calculation Agent under a Swap Transaction under the terms of an agreement incorporating the ISDA Definitions and under which:
	(x)     the Floating Rate Option is as specified in the relevant Final Terms;
	(y)     the Designated Maturity is a period specified in the relevant Final Terms; and
	(z)     the relevant Reset Date is the first day of that Interest Accrual Period unless otherwise specified in the relevant Final Terms.
	For the purposes of this sub-paragraph (A), “Floating Rate”, “Calculation Agent”, “Floating Rate Option”, “Designated Maturity”, “Reset Date” and “Swap Transaction” have the meanings given to those terms in the ISDA Definitions.
(B)	Screen Rate Determination for Floating Rate Instruments: Where Screen Rate Determination is specified in the relevant Final Terms as the manner in which the

24

Rate of Interest is to be determined, the Rate of Interest for each Interest Accrual Period shall be determined by the Calculation Agent at or about the Relevant Time on the Interest Determination Date in respect of such Interest Accrual Period in accordance with the following:

(x) if the Primary Source for Floating Rate is a Page, subject as provided below, the Rate of Interest shall be:

(a)	the Relevant Rate (where such Relevant Rate on such Page is a composite quotation or is customarily supplied by one entity); or
(b)	the arithmetic mean of the Relevant Rates of the persons whose Relevant Rates appear on that Page,
	in each case appearing on such Page at the Relevant Time on the Interest Determination Date;

(y)

if the Primary Source for the Floating Rate is Reference Banks or if sub-paragraph (x) (a) applies and no Relevant Rate appears on the Page at the Relevant Time on the Interest Determination Date or if sub-paragraph (x) (b) above applies and fewer than two Relevant Rates appear on the Page at the Relevant Time on the Interest Determination Date, subject as provided below, the Rate of Interest shall be the arithmetic mean of the Relevant Rates that each of the Reference Banks is quoting to leading banks in the Relevant Financial Centre at the Relevant Time on the Interest Determination Date, as determined by the Calculation Agent; and

(z)

if paragraph (y) above applies and the Calculation Agent determines that fewer than two Reference Banks are so quoting Relevant Rates, subject as provided below, the Rate of Interest shall be the arithmetic mean of the rates per annum (expressed as a percentage) that the Calculation Agent determines to be the rates (being the nearest equivalent to the Benchmark) in respect of a Representative Amount of the Specified Currency that at least two out of five leading banks selected by the Calculation Agent in the principal financial centre of the country of the Specified Currency or, if the Specified Currency is Euro in those Member States of the European Union which are participating in European economic and monetary union as selected by the Calculation Agent (the “Principal Financial Centre”) are quoting at or about the Relevant Time on the date on which such banks would customarily quote such rates for a period commencing on the Effective Date for a period equivalent to the Specified Duration (I) to leading banks carrying on business in Europe, or (if the Calculation Agent determines that fewer than two of such banks are so quoting to leading banks in Europe) (II) to leading banks carrying on business in the Principal Financial Centre; except that, if fewer than two of such banks are so quoting to leading banks in the Principal Financial Centre, the Rate of Interest shall be the Rate of Interest determined on the previous Interest Determination Date (after readjustment for any difference between any Margin, Rate Multiplier or Maximum or Minimum Rate of Interest applicable to the preceding Interest Accrual Period and to the relevant Interest Accrual Period).

3.2.4	Rate of Interest for Index Linked Interest Instruments
	The Rate of Interest in respect of Index Linked Interest Instruments for each Interest Accrual Period shall be determined in the manner specified in the relevant Final Terms and

25

interest will accrue by reference to an Index or Formula as specified in the relevant Final Terms

	(a)	Zero Coupon Instruments
		Where an Instrument, the Interest Basis of which is specified to be Zero Coupon, is repayable prior to the Maturity Date and is not paid when due, the amount due and payable prior to the Maturity Date shall be the Early Redemption Amount of such Instrument. As from the Maturity Date, the Rate of Interest for any overdue principal of such an Instrument shall be a rate per annum (expressed as a percentage) equal to the Amortisation Yield (as defined in Condition 5.4.1(b)).
	(b)	Dual Currency Instruments
		In the case of Dual Currency Instruments, if the rate or amount of interest falls to be determined by reference to a Rate of Exchange or a method of calculating a Rate of Exchange, the rate or amount of interest payable shall be determined in the manner specified in the relevant Final Terms.
	(c)	Partly Paid Instruments
		In the case of Partly Paid Instruments (other than Partly Paid Instruments which are Zero Coupon Instruments), interest will accrue as previously stated on the paid-up nominal amount of such Instruments and otherwise as specified in the relevant Final Terms.
	(d)	Accrual of Interest
��		Interest shall cease to accrue on each Instrument on the due date for redemption unless, upon due presentation, payment is improperly withheld or refused, in which event interest shall continue to accrue (as well after as before judgment) at the Rate of Interest in the manner provided in this Condition 3 to the Relevant Date (as defined in Condition 7).
	(e)	Margin, Maximum/Minimum Rates of Interest, Instalment Amounts and Redemption Amounts, Rate Multipliers and Rounding

(i)	If any Margin or Rate Multiplier is specified in the relevant Final Terms (either (x) generally, or (y) in relation to one or more Interest Accrual Periods), an adjustment shall be made to all Rates of Interest, in the case of (x), or the Rates of Interest for the specified Interest Accrual Periods, in the case of (y), calculated in accordance with Condition 3.2 above, by adding (if a positive number) or subtracting (if a negative number) the absolute value of such Margin or multiplying by such Rate Multiplier, subject always to the next paragraph.
(ii)	If any Maximum or Minimum Rate of Interest, Instalment Amount or Redemption Amount is specified in the relevant Final Terms, then any Rate of Interest, Instalment Amount or Redemption Amount shall be subject to such maximum or minimum, as the case may be.
(iii)	For the purposes of any calculations required pursuant to these Conditions (unless otherwise specified), (x) all percentages resulting from such calculations shall be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (with halves being rounded up), (y) all figures shall be rounded to seven significant figures (with halves being rounded up) and (z) all currency amounts that fall due and payable shall be rounded to the nearest unit of such currency (with halves being rounded up),

26

save in the case of yen, which shall be rounded down to the nearest yen. For these purposes “unit” means the lowest amount of such currency which is available as legal tender in the country of such currency.

(f)	Calculations
	The amount of interest payable per Calculation Amount in respect of any Instrument for any Interest Accrual Period shall be equal to the product of the Rate of Interest, the Calculation Amount specified thereon, and the Day Count Fraction for such Interest Accrual Period, unless an Interest Amount (or a formula for its calculation) is applicable to such Interest Accrual Period, in which case the amount of interest payable per Calculation Amount in respect of such Instrument for such Interest Accrual Period shall equal such Interest Amount (or be calculated in accordance with such formula). Where any Interest Period comprises two or more Interest Accrual Periods, the amount of interest payable per Calculation Amount in respect of such Interest Period shall be the sum of the Interest Amounts payable in respect of each of those Interest Accrual Periods. In respect of any other period for which interest is required to be calculated, the provisions above shall apply save that the Day Count Fraction shall be for the period for which interest is required to be calculated.
(g)	Determination and Publication of Rates of Interest, Interest Amounts, Final Redemption Amounts, Early Redemption Amounts, Optional Redemption Amounts and Instalment Amounts
	As soon as practicable after the Relevant Time on each Interest Determination Date, or such other time on such date as the Calculation Agent may be required to calculate any rate or amount, obtain any quotation or make any determination or calculation, it shall determine such rate and calculate the Interest Amounts in respect of each Specified Denomination of the Instruments for the relevant Interest Accrual Period, calculate the Redemption Amount or Instalment Amount, obtain such quote or make such determination or calculation, as the case may be, and cause the Rate of Interest and the Interest Amounts for each Interest Period and the relevant Interest Payment Date and, if required to be calculated, the Final Redemption Amount, Early Redemption Amount, Optional Redemption Amount or any Instalment Amount to be notified to the Trustee, the Issuer,[ the Guarantor,]* each of the Paying Agents, the Instrumentholders, any other Calculation Agent appointed in respect of the Instruments that is to make a further calculation upon receipt of such information and, if the Instruments are listed on a stock exchange and the rules of such exchange so require, such exchange as soon as possible after their determination but in no event later than (i) the commencement of the relevant Interest Period, if determined prior to such time, in the case of notification to such exchange of a Rate of Interest and Interest Amount, or (ii) in all other cases, the fourth Business Day after such determination. Where any Interest Payment Date or Interest Period Date is subject to adjustment pursuant to Condition 3.2.2, the Interest Amounts and the Interest Payment Date so published may subsequently be amended (or appropriate alternative arrangements made with the consent of the Trustee by way of adjustment) without notice in the event of an extension or shortening of the Interest Period. If the Instruments become due and payable under Condition 9, the accrued interest and the Rate of Interest payable in respect of the Instruments shall nevertheless continue to be calculated as previously in accordance with this Condition but no publication of the Rate of Interest or the Interest Amount so calculated need be made unless the Trustee otherwise requires. The determination of any rate or amount, the obtaining of each quotation and the making of each determination or calculation by the Calculation Agent(s) shall (in the absence of manifest error) be final and binding upon all parties.

27

(h)	Determination or Calculation by Trustee
	If the Calculation Agent does not at any time for any reason determine or calculate the Rate of Interest for an Interest Period or any Interest Amount, Instalment Amount, Final Redemption Amount, Early Redemption Amount or Optional Redemption Amount the Trustee shall do so (or shall appoint an agent on its behalf to do so) and such determination or calculation shall be deemed to have been made by the Calculation Agent.

4.3	Changes in Circumstances Affecting the Index

(i)

Change in base: If at any time and from time to time the Index is changed by the substitution of a new base therefor, then with effect from the month from and including that in which such substitution takes effect or the first date from and including that on which such substitution takes effect, as the case may be, (1) the definition of “Index” and “Index Figure” in Condition 4.1 shall be deemed to refer to the new date or month in substitution for January 1987 (or, as the case may be, to such other date or month as may have been substituted therefor), and (2) the new Base Index Figure shall be the product of the existing Base Index Figure and the Index Figure for the date on which such substitution takes effect, divided by the Index Figure for the date immediately preceding the date on which such substitution takes effect.

(ii)

Delay in publication of Index if sub-paragraph (i) of the definition of Index Figure is applicable: If the Index Figure which is normally published in the seventh month and which relates to the eighth month (the “relevant month”) before the month in which a payment is due to be made is not published on or before the fourteenth business day before the date

4.4

Application of Changes

Where the provisions of Condition 4.3(ii) or Condition 4.3(iii) apply, the determination of the Indexation Adviser as to the Index Figure applicable to the month in which the date for payment falls or the date for payment, as the case may be, shall be conclusive and binding. If, an Index Figure having been applied pursuant to Condition 4.3(ii)(2) or Condition 4.3(iii)(2), the Index Figure relating to the relevant month or relevant calculation month, as the case may be, is subsequently published while an Instrument is still outstanding, then:

(i)

in relation to a payment of principal or interest in respect of such Instrument other than upon final redemption of such Instrument, the principal or interest (as the case may be) next payable after the date of such subsequent publication shall be increased or reduced, as the case may be, by an amount equal to the shortfall or excess, as the case may be, of the amount of the relevant payment made on the basis of the Index Figure applicable by virtue of Condition 4.3(ii)(2) or Condition 4.3(iii)(2) below or above the amount of the relevant payment that would have been due if the Index Figure subsequently published had been published on or before the fourteenth business day before the date for payment; and

(ii)

in relation to a payment of principal or interest upon final redemption, no subsequent adjustment to amounts paid will be made.

4.5 Cessation of or Fundamental Changes to the Index

(i) If (1) the Trustee and the Issuer [and the Guarantor]* have been notified by the Calculation Agent that the Index has ceased to be published or (2) any change is made to the coverage or the basic calculation of the Index which constitutes a fundamental change which would, in the opinion of (A) the Issuer be materially prejudicial to the interests of the Issuer,[ or the Guarantor]* or (B) the Trustee acting solely on the advice of an Indexation Adviser, be materially prejudicial to the interests of the Instrumentholders, the Trustee will give written notice of such occurrence to the Issuer in the case of (B), and the Issuer[, the Guarantor]*

35

	and the Trustee (acting solely on the advice of the Indexation Adviser) together shall seek to agree for the purpose of the Instruments one or more adjustments to the Index or a substitute index (with or without adjustments) with the intention that the same should leave the Issuer[, the Guarantor]* and the Instrumentholders in no better and no worse position than they would have been had the Index not ceased to be published or the relevant fundamental change not been made.
(ii)	If the Issuer[, the Guarantor]* and the Trustee (acting solely on the advice of the Indexation Adviser) fail to reach agreement as mentioned above within 20 business days following the giving of notice as mentioned in paragraph (i), a bank or other person in London shall be appointed by the Issuer[, the Guarantor]* and the Trustee or, failing agreement on and the making of such appointment within 20 business days following the expiry of the 20 day period referred to above, by the Trustee (acting solely on the advice of the Indexation Adviser) (in each case, such bank or other person so appointed being referred to as the “Expert”), to determine for the purpose of the Instruments one or more adjustments to the Index or a substitute index (with or without adjustments) with the intention that the same should leave the Issuer[, the Guarantor]* and the Instrumentholders in no better and no worse position than they would have been had the Index not ceased to be published or the relevant fundamental change not been made. Any Expert so appointed shall act as an expert and not as an arbitrator and all fees, costs and expenses of the Expert and of any Indexation Adviser and of any of the Issuer[, the Guarantor]* and the Trustee in connection with such appointment shall be borne by the Issuer[ or the Guarantor]*.
(iii)	The Index shall be adjusted or replaced by a substitute index as agreed by the Issuer[, the Guarantor]* and the Trustee (acting solely on the advice of the Indexation Adviser) or as determined by the Expert pursuant to the foregoing paragraphs, as the case may be, and references in these Conditions to the Index and to any Index Figure shall be deemed amended in such manner as the Trustee (acting solely on the advice of the Indexation Adviser)[, the Guarantor]* and the Issuer agree are appropriate to give effect to such adjustment or replacement. Such amendments shall be effective from the date of such notification and binding upon the Issuer,[ the Guarantor and]* the Trustee and the Instrumentholders, and the Issuer [and the Guarantor]* shall give notice to the Instrumentholders in accordance with Condition 14 of such amendments as promptly as practicable following such notification.

4.6

Redemption for Index Reasons

If either (i) the Index Figure for three consecutive months is required to be determined on the basis of an Index Figure previously published as provided in Condition 4.3(ii)(2) and the Trustee has been notified by the Calculation Agent that publication of the Index has ceased or (ii) notice is published by Her Majesty’s Treasury, or on its behalf, following a change in relation to the Index, offering a right of redemption to the holders of the Reference Gilt, and (in either case) no amendment or substitution of the Index shall have been advised by the Indexation Adviser to the Issuer [and the Guarantor]* and such circumstances are continuing, the Issuer may, upon giving not more than 60 nor less than 30 days’ notice to the Instrumentholders in accordance with Condition 14, redeem all, but not some only, of the Instruments at their principal amount together with interest accrued but unpaid up to and including the date of redemption (in each case adjusted in accordance with Condition 4.2).

5 Redemption, Purchase and Options

5.1	Final Redemption
	Unless previously redeemed, purchased and cancelled as provided below, this Instrument will be redeemed at its Final Redemption Amount (which, unless otherwise provided, is its nominal

36

	amount) on the Maturity Date specified in the relevant Final Terms provided, however, that if this Instrument is a Perpetual Instrument it will only be redeemable and repayable in accordance with the following provisions of this Condition 5.

	If, on the occasion of the next payment in respect of the Instruments the Issuer [(or, if the Guarantee were called, the Guarantor)]* satisfies the Trustee immediately before the giving of the notice referred to below that it would be unable to make such payment without having to pay additional amounts as described in Condition 7, and such requirement to pay such additional amounts arises by reason of a change in the laws of the United Kingdom or any political sub-division of the United Kingdom or taxing authority in the United Kingdom or any political sub-division of the United Kingdom or in the official interpretation or application of the laws of the United Kingdom or any political sub-division of the United Kingdom or in any applicable double taxation treaty or convention, which change becomes effective on or after the date on which agreement is reached to issue the first Tranche of the Instruments, and such requirement cannot be avoided by the Issuer [(or the Guarantor, as the case may be)]* taking reasonable measures (such measures not involving any material additional payments by, or expense for, the Issuer [(or the Guarantor, a the case may be)]*), the Issuer may, at its option, on any Interest Payment Date or, if so specified in the relevant Final Terms, at any time, having given not less than 30 nor more than 45 days’ notice to the Instrumentholders in accordance with Condition 14, redeem all, but not some only, of the Instruments at their Early Redemption Amount together with interest accrued to the date of redemption provided that the date fixed for redemption shall not be earlier than 90 days prior to the earliest date on which the Issuer [(or the Guarantor, as the case may be)]* would be obliged to pay such additional amounts or make such withholding or deduction, as the case may be, were a payment in respect of the Instruments [(or the Guarantee, as the case may be)]* then due. Prior to the publication of any notice of redemption pursuant to this Condition 5.2, the Issuer shall deliver to the Trustee a certificate signed by two Directors of the Issuer [(or the Guarantor, as the case may be)]* stating that the requirement referred to above cannot be avoided by the Issuer [(or the Guarantor, as the case may be)]* taking reasonable measures available to it and the Trustee shall be entitled to accept such certificate as sufficient evidence of the satisfaction of the condition precedent set out above in which event it shall be conclusive and binding on Instrumentholders and Couponholders.
5.3	Purchases
	The Issuer[, the Guarantor]* and any of [its/their] subsidiary undertakings may at any time purchase Instruments (provided that all unmatured Receipts and Coupons and unexchanged Talons appertaining to them are attached or surrendered with them) in the open market or otherwise at any price.
5.4	Early Redemption

5.4.1 Zero Coupon Instruments:

(a)

The Early Redemption Amount payable in respect of any Zero Coupon Instrument, the Early Redemption Amount of which is not linked to an index and/or a formula, upon redemption of such Instrument pursuant to Condition 5.2 or upon it becoming due and payable as provided in Condition 9 shall be the Amortised Face Amount (calculated as provided below) of such Instrument unless otherwise specified in the relevant Final Terms.

(b)

Subject to the provisions of sub-paragraph (c) below, the Amortised Face Amount of any such Instrument shall be the scheduled Final Redemption Amount of such Instrument on the Maturity Date discounted at a rate per annum (expressed as a percentage) equal to the Amortisation Yield (which, if none is specified in the

37

relevant Final Terms, shall be such rate as would produce an Amortised Face Amount equal to the issue price of the Instruments if they were discounted back to their issue price on the Issue Date) compounded annually.

(c)

If the Early Redemption Amount payable in respect of any such Instrument, upon its redemption pursuant to Condition 5.2 or, if applicable, Condition 5.5 or 5.6 or upon it becoming due and payable as provided in Condition 9, is not paid when due, the Early Redemption Amount due and payable in respect of such Instrument shall be the Amortised Face Amount of such Instrument as defined in sub-paragraph (b) above, except that such sub-paragraph shall have effect as though the reference in that sub-paragraph to the date on which the Instrument becomes due and payable was replaced by a reference to the Relevant Date as defined in Condition 7. The calculation of the Amortised Face Amount in accordance with this sub-paragraph shall continue to be made (as well after as before judgment) until the Relevant Date, unless the Relevant Date falls on or after the Maturity Date, in which case the amount due and payable shall be the scheduled Final Redemption Amount of such Instrument on the Maturity Date together with any interest that may accrue in accordance with Condition 3.2.

	Where such calculation is to be made for a period of less than one year, it shall be made on the basis of the Day Count Fraction specified in the relevant Final Terms.
5.4.2	Other Instruments
	The Early Redemption Amount payable in respect of any Instrument (other than Instruments described in Condition 5.4.1 above), upon redemption of such Instrument pursuant to this Condition 5.4 or upon it becoming due and payable as provided in Condition 9, shall be the Final Redemption Amount unless otherwise specified in the relevant Final Terms.

5.5	Redemption at the Option of the Issuer and Exercise of Issuer’s Options
	If Call Option is specified in the relevant Final Terms, the Issuer may, on giving not less than 15 nor more than 30 days’ irrevocable notice to the Instrumentholders (or such other notice period as may be specified in the relevant Final Terms), redeem, or exercise any Issuer’s option in relation to, all or, if so provided, some of such Instruments on any Optional Redemption Date or Option Exercise Date, as the case may be. Any such redemption of Instruments shall be at their Optional Redemption Amount together with interest accrued to the date fixed for redemption. Any such redemption or exercise must relate to Instruments of a nominal amount at least equal to the minimum nominal amount (if any) to be redeemed specified hereon and no greater than the maximum nominal amount (if any) to be redeemed specified on this Instrument.
	All Instruments in respect of which any such notice is given shall be redeemed, or the Issuer’s option shall be exercised, on the date specified in such notice in accordance with this Condition.
	In the case of a partial redemption or a partial exercise of an Issuer’s option, the notice to Instrumentholders shall also contain the serial numbers of the Instruments to be redeemed, which shall have been drawn in such place as the Trustee may approve and in such manner as it deems appropriate, subject to compliance with any applicable laws, listing authority and stock exchange requirements.
5.6	Redemption at the Option of Instrumentholders and Exercise of Instrumentholders’ Options
	If Put Option is specified in the relevant Final Terms, the Issuer shall, at the option of the holder of any such Instrument, upon the holder of such Instrument giving not less than 15 nor more than 30 days’ notice to the Issuer (or such other notice period as may be specified on this Instrument)

38

	redeem such Instrument on the Optional Redemption Date(s) at its Optional Redemption Amount together with interest accrued to the date fixed for redemption.
	To exercise such option or any other Instrumentholders’ option which may be set out on this Instrument (which must be exercised on an Option Exercise Date) the holder must deposit such Instrument with any Paying Agent at its specified office, together with a duly completed option exercise notice (“Exercise Notice”) in the form obtainable from any Paying Agent within the Instrumentholders’ Option Period (as specified in the relevant Final Terms). No Instrument so deposited and option exercised may be withdrawn (except as provided in the Agency Agreement) without the prior consent of the Issuer.
5.7	Partly Paid Instruments
	Partly Paid Instruments will be redeemed, whether at maturity, early redemption or otherwise, in accordance with the provisions of this Condition and the provisions specified in the relevant Final Terms.
5.8	Redemption by Instalments
	Unless previously redeemed, purchased and cancelled as provided in this Condition 5, each Instrument which provides for Instalment Dates and Instalment Amounts will be partially redeemed on each Instalment Date at the Instalment Amount specified in the relevant Final Terms. The outstanding nominal amount of each such Instrument shall be reduced by the Instalment Amount (or, if such Instalment Amount is calculated by reference to a proportion of the nominal amount of such Instrument, such proportion) for all purposes with effect from the related Instalment Date, unless payment of the Instalment Amount is improperly withheld or refused on presentation of the related Receipt, in which case, such amount shall remain outstanding until the Relevant Date relating to such Instalment Amount.
5.9	Cancellation
	All Instruments redeemed pursuant to any of the foregoing provisions will be cancelled forthwith (together with all unmatured Receipts and Coupons and unexchanged Talons attached thereto). All Instruments purchased by or on behalf of the Issuer [, the Guarantor]* or any of [its/their] subsidiary undertakings may, at the option of the Issuer be held by or may be surrendered together with all unmatured Receipts and Coupons and all unexchanged Talons attached to them to a Paying Agent for cancellation, but may not be resold and when held by the Issuer [, the Guarantor]* or any of [its/their] respective subsidiary undertakings shall not entitle the holder to vote at any meeting of Instrumentholders and shall not be deemed to be outstanding for the purposes of calculating quorums at meetings of Instrumentholders or for the purposes of Condition 11.

6 Payments and Talons

6.1

Payments

Payments of principal and interest in respect of Instruments will, subject as mentioned below, be made against presentation and surrender of the relevant Receipts (in the case of payments of Instalment Amounts other than on the due date for redemption and provided that the Receipt is presented for payment together with its relative Instrument), Instruments (in the case of all other payments of principal and, in the case of interest, as specified in Condition 6.5.6) or Coupons (in the case of interest, save as specified in Condition 6.5.6), as the case may be, at the specified office of any Paying Agent outside the United States by a cheque payable in the currency in which such payment is due drawn on, or, at the option of the holder, by transfer to an account denominated in that currency with, a bank in the principal financial centre for that currency;

39

	provided that in the case of Euro, the transfer shall be in a city in which banks have access to the TARGET System.
6.2	Payments in the United States
	Notwithstanding the above, if any Instruments are denominated in U.S. dollars, payments in respect of them may be made at the specified office of any Paying Agent in New York City in the same manner as specified above if (a) the Issuer shall have appointed Paying Agents with specified offices outside the United States with the reasonable expectation that such Paying Agents would be able to make payment of the amounts on the Instruments in the manner provided above when due, (b) payment in full of such amounts at all such offices is illegal or effectively precluded by exchange controls or other similar restrictions on payment or receipt of such amounts and (c) such payment is then permitted by United States law, without involving, in the opinion of the Issuer, any adverse tax consequence to the Issuer.
6.3	Payments subject to Fiscal Laws etc.
	All payments are subject in all cases to any applicable fiscal or other laws, regulations and directives, but without prejudice to the provisions of Condition 7. No commission or expenses shall be charged to the Instrumentholders or Couponholders in respect of such payments.
6.4	Appointment of Agents
	The Issuing and Paying Agent, the Paying Agents and the Calculation Agent initially appointed by the Issuer [and the Guarantor]* and their respective specified offices are listed below. The Issuing and Paying Agent, the Paying Agents and the Calculation Agent act solely as agents of the Issuer [and the Guarantor]* and do not assume any obligation or relationship of agency or trust for or with any holder. The Issuer [and the Guarantor]* reserve[s] the right at any time with the approval of the Trustee to vary or terminate the appointment of the Issuing and Paying Agent, any other Paying Agent or the Calculation Agent and to appoint additional or other Paying Agents, provided that the Issuer shall at all times maintain (i) an Issuing and Paying Agent, (ii) a Paying Agent having a specified office in a continental European city, (iii) a Calculation Agent where the Conditions so require one, (iv) so long as the Instruments are listed on any stock exchange or admitted to listing by any other relevant authority, a Paying Agent having a specified office in such place as may be required by the rules and regulations of the relevant stock exchange or other relevant authority and (v) to the extent that the Issuer is able to do so and not provided for by the foregoing provisions of this Condition 6.4, a Paying Agent with a specified office in a European Union Member State that will not be obliged to withhold or deduct tax pursuant to European Council Directive 2003/48/EC or any other Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 or any law implementing or complying with, or introduced in order to conform to, such Directive. As used in these Conditions, the terms “Issuing and Paying Agent”, “Calculation Agent”, and “Paying Agent” include any additional or replacement Issuing and Paying Agent, Calculation Agent or Paying Agent appointed under this Condition.
	In addition, the Issuer [and the Guarantor]* shall forthwith appoint a Paying Agent in New York City in respect of any Instruments denominated in U.S. dollars in the circumstances described in Condition 6.2.
	Notice of any such change or any change of any specified office shall promptly be given to the Instrumentholders in accordance with Condition 14.
6.5	Unmatured Coupons and Receipts and unexchanged Talons:

6.5.1 Unless the Instrument provides that the relevant Coupons are to become void upon the due date for redemption of those Instruments, Instruments should be surrendered for payment together with all unmatured Coupons (if any) appertaining to them, failing

40

	which an amount equal to the face value of each missing unmatured Coupon (or, in the case of payment not being made in full, that proportion of the amount of such missing unmatured Coupon that the sum of principal so paid bears to the total principal due) will be deducted from the Final Redemption Amount, Early Redemption Amount or Optional Redemption Amount, as the case may be, due for payment. Any amount so deducted shall be paid in the manner mentioned above against surrender of such missing Coupon within a period of 10 years from the Relevant Date for the payment of such principal (whether or not such Coupon has become void pursuant to Condition 8).
6.5.2	If the relevant Instrument so provides, upon the due date for redemption of any Instrument, unmatured Coupons relating to such Instrument (whether or not attached) shall become void and no payment shall be made in respect of them.
6.5.3	If the relevant Instrument so provides, upon the due date for redemption of any Instrument, any unexchanged Talon relating to such Instrument (whether or not attached) shall become void and no Coupon shall be delivered in respect of such Talon.
6.5.4	Upon the due date for redemption of any Instrument which is redeemable in instalments, all Receipts relating to such Instrument having an Instalment Date falling on or after such due date (whether or not attached) shall become void and no payment shall be made in respect of them.
6.5.5	Where any Instrument which provides that the relevant Coupons are to become void upon the due date for redemption of those Instruments is presented for redemption without all unmatured Coupons and any unexchanged Talon relating to it, and where any Instrument is presented for redemption without any unexchanged Talon relating to it, redemption shall be made only against the provision of such indemnity as the Issuer may require.
6.5.6	If the due date for redemption of any Instrument is not a due date for payment of interest, interest accrued from the preceding due date for payment of interest or the Interest Commencement Date, as the case may be, shall only be payable against presentation (and surrender if appropriate) of the relevant Instrument. Interest accrued on an Instrument that only bears interest after its Maturity Date shall be payable on redemption of that Instrument against presentation of that Instrument.

6.6

Non-business days

If any date for payment in respect of any Instrument, Receipt or Coupon is not a business day, the holder shall not be entitled to payment until the next following business day nor to any interest or other sum in respect of such postponed payment. In this paragraph, “business day” means a day (other than a Saturday or a Sunday) on which banks and foreign exchange markets are open for business in the relevant place of presentation, in such jurisdictions as shall be specified as “Financial Centres” in the relevant Final Terms and:

6.6.1	(in the case of a payment in a currency other than Euro) where payment is to be made by transfer to an account maintained with a bank in the relevant currency, on which foreign exchange transactions may be carried on in the relevant currency in the principal financial centre of the country of such currency; or
6.6.2	(in the case of a payment in Euro), which is a TARGET Business Day.

41

6.7	Talons
	On or after the Interest Payment Date for the final Coupon forming part of a Coupon sheet issued in respect of any Instrument, the Talon forming part of such Coupon sheet may be surrendered at the specified office of the Issuing and Paying Agent in exchange for a further Coupon sheet (but excluding any Coupons which may have become void pursuant to Condition 8).

7

Taxation

All payments of principal and interest by or on behalf of the Issuer [or the Guarantor]* in respect of the Instruments, the Receipts and the Coupons [or under the Guarantee]* will be made without withholding or deduction for or on account of, any present or future taxes or duties of whatever nature imposed or levied by or on behalf of the United Kingdom or any political sub-division of the United Kingdom or any authority in or of the United Kingdom having power to tax, unless such withholding or deduction is compelled by law. In that event, the Issuer [or, as the case may be, the Guarantor]* will pay such additional amounts of principal and interest as will result in the payment to the Instrumentholders, Receiptholders or, as the case may be, the Couponholders of the amounts which would otherwise have been receivable in respect of the Instruments, Receipts or Coupons had no withholding or deduction been made, except that no such additional amounts shall be payable in respect of any Instrument, Receipt or Coupon presented for payment:

(a)	by or on behalf of, a person who is liable to such taxes or duties in respect of such Instrument, Receipt or Coupon by reason of his having some connection with the United Kingdom other than the mere holding of such Instrument, Receipt or Coupon; or
(b)	by or on behalf of a person who would not be liable or subject to such deduction or withholding by making a declaration of non-residence or other claim for exemption to a tax authority; or
(c)	more than 30 days after the Relevant Date except to the extent that the holder would have been entitled to such additional amounts on presenting the same for payment on such thirtieth day; or
(d)	where such withholding or deduction is imposed on a payment to an individual and is required to be made pursuant to European Council Directive 2003/48/EC or any other Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 or any law implementing or complying with, or introduced in order to conform to, such Directive; or
(e)	by or on behalf of a holder who would have been able to avoid such withholding or deduction (i) by presenting the relevant Instrument, Receipt or Coupon to another Paying Agent in a Member State of the European Union; or (ii) by satisfying any statutory or procedural requirements (including, without limitation, the provision of information).

As used in these Conditions, “Relevant Date” in respect of any Instrument, Receipt or Coupon means the date on which payment in respect of it first becomes due or (if any amount of the money payable is improperly withheld or refused) the date on which payment in full of the amount outstanding is made or (if earlier) the date on which notice is duly given to the Instrumentholders in accordance with Condition 14 that, upon further presentation of the Instrument, Receipt or Coupon being made in accordance with the Conditions, such payment will be made, provided that payment is in fact made upon such presentation. References in these Conditions to (i) “principal” shall be deemed to include any premium payable in respect of the Instruments, all Instalment Amounts, Final Redemption Amounts, Early Redemption Amounts, Optional Redemption Amounts, Amortised Face Amounts and all other amounts in the nature of principal payable pursuant to Condition 5 or any amendment or supplement to it, (ii) “interest” shall be deemed to include all Interest Amounts and all other amounts payable pursuant to Condition 3 or any amendment or supplement to it and (iii) “principal” and/or “interest” shall be deemed to include any additional amounts which may be payable under this Condition or any undertaking given in addition to or in substitution for it under the Trust Deed.

9	Events of Default
	If any of the following events (each an “Event of Default”) occurs and is continuing, the Trustee at its discretion may, and if so requested by the holders of at least one-quarter in nominal amount of the Instruments then outstanding or if so directed by an Extraordinary Resolution shall, give notice to the Issuer at its registered office that the Instruments are, and they shall accordingly immediately become due and repayable at their Redemption Amount together with accrued interest (if any) to the date of payment:

(a)	Non-Payment: there is default for more than 30 days in the payment of any principal or interest due in respect of the Instruments; or
(b)	Breach of Other Obligations: there is default in the performance or observance by the Issuer [or the Guarantor]* of any other obligation or provision under the Trust Deed or the Instruments (other than any obligation for the payment of any principal or interest in respect of the Instruments) which default is incapable of remedy or, if in the opinion of the Trustee capable of remedy, is not remedied within 90 days after notice of such default shall have been given to the Issuer [or the Guarantor]* by the Trustee; or
(c)	Winding-up: a resolution is passed, or a final order of a court in the United Kingdom is made and, where possible, not discharged or stayed within a period of 90 days, that the Issuer [or the Guarantor]* be wound up or dissolved; or
(d)	Enforcement Proceedings: attachment is made of the whole or substantially the whole of the assets or undertaking of the Issuer [or the Guarantor]* and such attachment is not released or cancelled within 90 days or an encumbrancer takes possession or an administrative or other receiver or similar officer is appointed of the whole or substantially the whole of the assets or undertaking of the Issuer [or the Guarantor]* or an administration or similar order is made in relation to the Issuer [or the Guarantor]* and such taking of possession, appointment or order is not released, discharged or cancelled within 90 days; or

(f)	Bankruptcy: the Issuer [or the Guarantor]* is adjudged bankrupt or insolvent by a court of competent jurisdiction in its country of incorporation,

	provided that in the case of paragraph (b) the Trustee shall have certified that in its opinion such event is materially prejudicial to the interests of the Instrumentholders.
	Any such notice by the Trustee to the Issuer shall specify the serial number(s) of the Instrument(s) concerned.
10	Enforcement
	The Trustee may, at its discretion and without further notice, institute such proceedings against the Issuer as it may think fit to enforce any obligation, condition or provision binding on the Issuer under the Instruments or under the Trust Deed, but shall not be bound to do so unless:

(a) it has been so directed by an Extraordinary Resolution or in writing by the holders of at least one-quarter of the principal amount of the Instruments outstanding; and

43

(b) it has been indemnified to its satisfaction.

	No Instrumentholder, Receiptholder or Couponholder shall be entitled to institute proceedings directly against the Issuer unless the Trustee, having become bound to proceed as specified above, fails to do so within a reasonable time and such failure is continuing.
11	Meetings of Instrumentholders, Modifications and Substitution

11.1	Meetings of Instrumentholders
	The Trust Deed contains provisions for convening meetings of Instrumentholders to consider any matter affecting their interests, including the sanctioning by Extraordinary Resolution (as defined in the Trust Deed) of a modification of any of these Conditions or any provisions of the Trust Deed. An Extraordinary Resolution duly passed at any such meeting shall be binding on Instrumentholders (whether or not they were present at the meeting at which such resolution was passed) and on all Couponholders, except that any Extraordinary Resolution proposed,inter alia, (i) to amend the dates of maturity or redemption of the Instruments, any Instalment Date or any date for payment of interest on the Instruments, (ii) to reduce or cancel the nominal amount of, or any Instalment Amount of, or any premium payable on redemption of, the Instruments, (iii) to reduce the rate or rates of interest in respect of the Instruments or to vary the method or basis of calculating the rate or rates or amount of interest or the basis for calculating any Interest Amount in respect of the Instruments, (iv) if a Minimum and/or a Maximum Rate of Interest is shown on the face of the Instrument, to reduce any such Minimum and/or Maximum Rate of Interest, (v) to vary any method of calculating the Final Redemption Amount, the Early Redemption Amount or the Optional Redemption Amount, (vi) to take any steps that as specified in this Instrument may only be taken following approval by an Extraordinary Resolution to which the special quorum provisions apply [,or] (vii) to modify the provisions concerning the quorum required at any meeting of Instrumentholders or the majority required to pass the Extraordinary Resolution [or (viii) to modify or cancel the Guarantee]* will only be binding if passed at a meeting of the Instrumentholders (or at any adjournment of that meeting) at which a special quorum (as defined in the Trust Deed) is present. A resolution in writing signed by the holders of not less than 95 per cent. in nominal amount of the Instruments will be binding on all Instrumentholders and Couponholders. The Issuer may convene a meeting of Instrumentholders jointly with the holders of all other instruments issued pursuant to the Agency Agreement and not forming a single series with the Instruments to which meeting the provisions referred to above apply as if all such instruments formed part of the same series, provided that the proposals to be considered at such meeting affect the rights of the holders of the instruments of each series attending the meeting in identical respects (save insofar as the Conditions applicable to each such series are not identical).
11.2	Modification of the Trust Deed
	The Trustee may agree, without the consent of the Instrumentholders or Couponholders, to (i) any modification of any of the provisions of the Trust Deed that is of a formal, minor or technical nature or is made to correct a manifest error, and (ii) any other modification (except as mentioned in the Trust Deed), and any waiver or authorisation of any breach or proposed breach, of any of the provisions of the Trust Deed that is in the opinion of the Trustee not materially prejudicial to the interests of the Instrumentholders. Any such modification, authorisation or waiver shall be binding on the Instrumentholders and the Couponholders and, if the Trustee so requires, such modification shall be notified to the Instrumentholders as soon as practicable.
11.3	Substitution
	The Trust Deed contains provisions permitting the Trustee to agree, subject to such amendment of the Trust Deed and such other conditions as the Trustee may require, but without the consent of the Instrumentholders or the Couponholders, to the substitution of [a Successor in Business (as

44

	defined in the Trust Deed) or any subsidiary/any other company]± in place of the Issuer or of any previous substituted company, as principal debtor under the Trust Deed and the Instruments [and the substitution of the Guarantor’s Successor in Business (as defined in the Trust Deed) or any subsidiary of the Guarantor in place of the Guarantor]*. In the case of such a substitution the Trustee may agree, without the consent of the Instrumentholders or the Couponholders, to a change of the law governing the Instruments, the Receipts, the Coupons, the Talons and/or the Trust Deed provided that such change would not in the opinion of the Trustee be materially prejudicial to the interests of the Instrumentholders.
11.4	Entitlement of the Trustee
	In connection with the exercise of its functions (including but not limited to those referred to in this Condition) the Trustee shall have regard to the interests of the Instrumentholders as a class and shall not have regard to the consequences of such exercise for individual Instrumentholders or Couponholders and the Trustee shall not be entitled to require, nor shall any Instrumentholder or Couponholder be entitled to claim, from the Issuer [or the Guarantor]* any indemnification or payment in respect of any tax consequence of any such exercise upon individual Instrumentholders or Couponholders.

12	Replacement of Instruments, Receipts, Coupons and Talons
	If an Instrument, Receipt, Coupon or Talon is lost, stolen, mutilated, defaced or destroyed, it may be replaced, subject to applicable laws, listing authority and stock exchange regulations, at the specified office of such other Paying Agent as may from time to time be designated by the Issuer[ or the Guarantor]* for the purpose and notice of whose designation is given to Instrumentholders in accordance with Condition 14 on payment by the claimant of the fees and costs incurred in connection with that replacement and on such terms as to evidence, security and indemnity (which may provide,inter alia, that if the allegedly lost, stolen or destroyed Instrument, Receipt, Coupon or Talon is subsequently presented for payment or, as the case may be, for exchange for further Coupons, there shall be paid to the Issuer[ or the Guarantor]* on demand the amount payable by the Issuer[ or the Guarantor]* in respect of such Instruments, Receipts, Coupons or further Coupons) and otherwise as the Issuer[ or the Guarantor]* may require. Mutilated or defaced Instruments, Receipts, Coupons or Talons must be surrendered before replacements will be issued.
13	Further Issues
	The Issuer may from time to time without the consent of the Instrumentholders or Couponholders create and issue further instruments having the same terms and conditions as the Instruments and so that such further issue shall be consolidated and form a single series with such Instruments. References in these Conditions to the Instruments include (unless the context requires otherwise) any other instruments issued pursuant to this Condition and forming a single series with the Instruments. Any such further instruments forming a single series with Instruments constituted by the Trust Deed or any deed supplemental to it shall, and any other instruments may (with the consent of the Trustee), be constituted by the Trust Deed.
	The Trust Deed contains provisions for convening a single meeting of the Instrumentholders and the holders of instruments of other series if the Trustee so decides.

45

14	Notices
	All notices to the Instrumentholders will be valid if published in a daily English language newspaper of general circulation in the United Kingdom (which is expected to be the Financial Times). If in the opinion of the Trustee any such publication is not practicable, notice shall be validly given if published in another leading daily English language newspaper with general circulation in Europe. Any such notice shall be deemed to have been given on the date of such publication or, if published more than once or on different dates, on the first date on which publication is made, as provided above.
	Couponholders shall be deemed for all purposes to have notice of the contents of any notice given to the holders of Instruments in accordance with this Condition.
15	Indemnification of Trustee
	The Trust Deed contains provisions for the indemnification of the Trustee and for its relief from responsibility, including provisions relieving it from any obligation to take proceedings to enforce repayment unless indemnified to its satisfaction. The Trustee is entitled to enter into business transactions with the Issuer[, the Guarantor]* or any of [its/their] subsidiary undertakings, parent undertakings, joint ventures or associated undertakings without accounting for any profit resulting from these transactions and to act as trustee for the holders of any other securities issued by the Issuer or any of its subsidiary undertakings, parent undertakings, joint ventures or associated undertakings.
16	Contracts (Rights of Third Parties) Act 1999
	No person shall have any right to enforce any term or condition of the Instruments under the Contracts (Rights of Third Parties) Act 1999.

17 Governing Law and Jurisdiction

(a)	The Instruments and all matters arising from or connected with the Instruments are governed by, and shall be construed in accordance with, English law.
(b)	The courts of England have exclusive jurisdiction to settle any dispute (a “Dispute”), arising from or connected with the Instruments.
(c)	[Each of the]* /[The] Issuer[, and the Guarantor]* agrees that the courts of England are the most appropriate and convenient courts to settle any Dispute and, accordingly, that it will not argue to the contrary.
(d)	Nothing in this Condition 17 prevents the Trustee or any Instrumentholder from taking proceedings relating to a Dispute (“Proceedings”) in any other courts with jurisdiction. To the extent allowed by law, the Trustee or Instrumentholders may take concurrent Proceedings in any number of jurisdictions.

SUMMARY OF PROVISIONS
RELATING TO THE INSTRUMENTS WHILE IN GLOBAL FORM

Initial Issue of Instruments

Upon the initial deposit of a Global Instrument with a common depositary for Euroclear and Clearstream, Luxembourg (the “Common Depositary”), Euroclear or Clearstream, Luxembourg will credit each subscriber with a nominal amount of Instruments equal to the nominal amount of those Instruments for which it has subscribed and paid.

If the Global Instruments are stated in the applicable Final Terms to be issued in NGN form, they are intended to be eligible collateral for Eurosystem monetary policy and the Global Instruments will be delivered on or prior to the original issue date of the Tranche to a Common Safekeeper. Depositing the Global Instruments with the Common Safekeeper does not necessarily mean that the Instruments will be recognised as eligible collateral for Eurosystem monetary policy and intra-day credit operations by the Eurosystem either upon issue, or at any or all times during their life. Such recognition will depend upon satisfaction of the Eurosystem eligibility criteria.

Global Instruments which are issued in CGN form may be delivered on or prior to the original issue date of the Tranche to a Common Depositary.

If the Global Instrument is a CGN, upon the initial deposit of a Global Instrument with a common depositary for Euroclear and Clearstream, Luxembourg (the “Common Depositary”), Euroclear or Clearstream, Luxembourg will credit each subscriber with a nominal amount of Instruments equal to the nominal amount thereof for which it has subscribed and paid. If the Global Instrument is an NGN, the nominal amount of the Instruments shall be the aggregate amount from time to time entered in the records of Euroclear or Clearstream, Luxembourg. The records of such clearing system shall be conclusive evidence of the nominal amount of Instruments represented by the Global Instrument and a statement issued by such clearing system at any time shall be conclusive evidence of the records of the relevant clearing system at that time.

Instruments which are initially deposited with the Common Depositary may also be credited to the accounts of subscribers with (if indicated in the relevant Final Terms) other clearing systems through direct or indirect accounts with Euroclear and Clearstream, Luxembourg held by such other clearing systems. Conversely, Instruments that are initially deposited with another clearing system may similarly be credited to the accounts of subscribers with Euroclear, Clearstream, Luxembourg or other clearing systems.

Relationship of Accountholders with Clearing Systems

Each of the persons shown in the records of Euroclear, Clearstream, Luxembourg or any other clearing system as the holder of an Instrument represented by a Global Instrument must look solely to Euroclear, Clearstream, Luxembourg or such clearing system (as the case may be) for his share of each payment made by the relevant Issuer to the bearer of such Global Instrument and in relation to all other rights arising under the Global Instruments, subject to and in accordance with the respective rules and procedures of Euroclear, Clearstream, Luxembourg or such clearing systems (as the case may be). Such persons shall have no claim directly against the relevant Issuer in respect of payments. due on the Instruments for so long as the Instruments are represented by such Global Instrument and such obligations of such Issuer will be discharged by payment to the bearer of such Global Instrument in respect of each amount so paid.

The Trustee may call for any certificate or other document to be issued by Euroclear, Clearstream, Luxembourg or any other clearing system as to the principal amount of Instruments represented by a Global Instrument standing to the account of any person. Any such certificate or other document shall, in the absence of manifest error, be conclusive and binding for all purposes. Any such certificate or other

47

document may comprise any form of statement or print out of electronic records provided by the relevant clearing system (including Euroclear’s EUCLID or Clearstream, Luxembourg’s Cedcom system) in accordance with its usual procedures and in which the holder of a particular principal amount of any other clearing system is clearly identified together with the amount of such holding. The Trustee shall not be liable to any person by reason of having accepted as valid or not having rejected any certificate or other document to such effect purporting to be issued by Euroclear, Clearstream, Luxembourg or any other clearing system and subsequently found to be forged or not authentic.

Exchange

1 Temporary Global Instruments

Each temporary Global Instrument will be exchangeable, free of charge to the holder, on or after its Exchange Date:

1.1	if the relevant Final Terms indicates that such Global Instrument is issued in compliance with the C Rules or in a transaction to which TEFRA is not applicable (as to which, see “Summary of the Programme — Selling Restrictions”), in whole, but not in part, for the Definitive Instruments defined and described below; and
1.2	otherwise, in whole or in part upon certification as to non-U.S. beneficial ownership in the form set out in the Agency Agreement for interests in a permanent Global Instrument or, if so provided in the relevant Final Terms, for Definitive Instruments.

2	Permanent Global Instruments
	Each permanent Global Instrument will be exchangeable, free of charge to the holder, on or after its Exchange Date in whole but not, except as provided under “Partial Exchange of Permanent Global Instruments”, in part for Definitive Instruments if the permanent Global Instrument is held on behalf of Euroclear or Clearstream, Luxembourg or any other clearing system (an “Alternative Clearing System”) and any such clearing system is closed for business for a continuous period of 14 days (other than by reason of holidays, statutory or otherwise) or announces an intention permanently to cease business or in fact does so.
	In the event that a Global Instrument is exchanged for Definitive Instruments, such Definitive Instruments shall be issued in Specified Denomination(s) only. An Instrumentholder who holds a principal amount of less than the minimum Specified Denomination will not receive a definitive Note in respect of such holding and would need to purchase a principal amount of Instruments such that it holds an amount equal to one or more Specified Denominations.

3

Partial Exchange of Permanent Global Instruments

For so long as a permanent Global Instrument is held on behalf of a clearing system and the rules of that clearing system permit, such permanent Global Instrument will be exchangeable in part on one or more occasions for Definitive Instruments (i) if principal in respect of any Instruments is not paid when due or (ii) if so provided in, and in accordance with, the Conditions (which will be set out in the relevant Final Terms) relating to Partly Paid Instruments.

4

Delivery of Instruments

If the Global Instrument is a CGN, on or after any due date for exchange the holder of a Global Instrument may surrender such Global Instrument or, in the case of a partial exchange, present it for endorsement to or to the order of the Issuing and Paying Agent. In exchange for any Global Instrument, or the part of that Global Instrument to be exchanged, the relevant Issuer will (i) in the case of a

48

temporary Global Instrument exchangeable for a permanent Global Instrument, deliver, or procure the delivery of, a permanent Global Instrument in an aggregate nominal amount equal to that of the whole or that part of a temporary Global Instrument that is being exchanged or, in the case of a subsequent exchange, endorse, or procure the endorsement of, a permanent Global Instrument to reflect such exchange or (ii) in the case of a Global Instrument exchangeable for Definitive Instruments, deliver, or procure the delivery of, an equal aggregate nominal amount of duly executed and authenticated Definitive Instruments or, if the Global Instrument is an NGN, the relevant Issuer will procure that details of such exchange be enteredpro ratain the records of the relevant clearing system. In this Prospectus, “Definitive Instruments” means, in relation to any Global Instrument, the Definitive Instruments for which such Global Instrument may be exchanged (if appropriate, having attached to them all Coupons and Receipts in respect of interest or Instalment Amounts that have not already been paid on the Global Instrument and a Talon). Definitive Instruments will be security printed in accordance with any applicable legal and stock exchange requirements in or substantially in the form set out in the Schedules to the Trust Deed. On exchange in full of each permanent Global Instrument, the relevant Issuer will, if the holder so requests, procure that it is cancelled and returned to the holder together with the relevant Definitive Instruments.

5	Exchange Date
	“Exchange Date” means, in relation to a temporary Global Instrument, the day falling after the expiry of 40 days after its issue date and, in relation to a permanent Global Instrument, a day falling not less than 60 days, or in the case of failure to pay principal in respect of any Instruments when due 30 days, after that on which the notice requiring exchange is given and on which banks are open for business in the city in which the specified office of the Issuing and Paying Agent is located and in the city in which the relevant clearing system is located.
	Amendment to Conditions
	The temporary Global Instruments and permanent Global Instruments contain provisions that apply to the Instruments which they represent, some of which modify the effect of the terms and conditions of the Instruments set out in this Prospectus. The following is a summary of certain of those provisions:
1	Payments
	No payment falling due after the Exchange Date will be made on any Global Instrument unless exchange for an interest in a permanent Global Instrument or for Definitive Instruments is improperly withheld or refused. Payments on any temporary Global Instrument issued in compliance with the D Rules before the Exchange Date will only be made against presentation of certification as to non-U.S. beneficial ownership in the form set out in the Agency Agreement. All payments in respect of Instruments represented by a Global Instrument in CGN form will be made against presentation for endorsement and, if no further payment falls to be made in respect of the Instruments, surrender of that Global Instrument to or to the order of the Issuing and Paying Agent or such other Paying Agent as shall have been notified to the Instrumentholders for such purpose. If the Global Instrument is a CGN, a record of each payment so made will be endorsed on each Global Instrument, which endorsement will beprima facie evidence that such payment has been made in respect of the Instruments. Condition 6.4(v) and Condition 7(e) will apply to the Definitive Instruments only. If the Global Instrument is an NGN, the relevant Issuer shall procure that details of each such payment shall be enteredpro ratain the records of the relevant clearing system and in the case of payments of principal, the nominal amount of the Instruments recorded in the records of the relevant clearing system and represented by the Global Instrument will be reduced accordingly. Payments under the NGN will be made to its holder. Each payment so made will discharge the relevant Issuer’s obligations in respect thereof. Any failure to make the entries in the records of the relevant clearing system shall not affect such discharge.

49

	The records of the relevant clearing systems which reflect the amount of the Instrumentholders’ interests in the instruments shall be conclusive evidence of the nominal amount of Instruments represented by the Global Instruments.
2	Prescription
	Claims against the relevant Issuer in respect of Instruments which are represented by a permanent Global Instrument will become void unless it is presented for payment within a period of 10 years (in the case of principal) and five years (in the case of interest) from the appropriate Relevant Date (as defined in Condition 7).
3	Meetings
	The holder of a permanent Global Instrument shall (unless such permanent Global Instrument represents only one Instrument) be treated as being two persons for the purposes of any quorum requirements of a meeting of Instrumentholders and, at any such meeting, as having one vote in respect of each integral currency unit of the Specified Currency of the Instruments for which it may be exchanged in accordance with its terms.
4	Cancellation
	Cancellation of any Instrument represented by a permanent Global Instrument which is required by the Conditions to be cancelled (other than upon its redemption) will be effected by reduction in the nominal amount of the relevant permanent Global Instrument.
5	Purchase
	Instruments represented by a permanent Global Instrument may only be purchased by the relevant Issuer or any of its subsidiary undertakings if they are purchased together with the rights to receive all future payments of interest and Instalment Amounts (if any) on those Instruments.
6	Issuer’s Option
	Any option of the relevant Issuer provided for in the Conditions of any Instruments while such Instruments are represented by a permanent Global Instrument shall be exercised by such Issuer giving notice to the Instrumentholders within the time limits set out in and containing the information required by the Conditions, except that the notice shall not be required to contain the serial numbers of Instruments drawn in the case of a partial exercise of an option and accordingly no drawing of Instruments shall be required. In the event that any option of such Issuer is exercised in respect of some but not all of the Instruments of any Series, the rights of accountholders with a clearing system or Approved Intermediary in respect of the Instruments will be governed by the standard procedures of Euroclear, Clearstream, Luxembourg (to be reflected in the records of Euroclear and Clearstream, Luxembourg either as a pool factor or as a reduction in nominal amount, at their discretion) or any other clearing system (as the case may be).
7	Instrumentholders’ Options
	Any option of the Instrumentholders provided for in the Conditions of any Instruments while such Instruments are represented by a permanent Global Instrument may be exercised by the holder of the permanent Global Instrument giving notice to the Issuing and Paying Agent within the time limits relating to the deposit of Instruments with a Paying Agent set out in the Conditions substantially in the form of the notice available from any Paying Agent, except that the notice shall not be required to contain the serial numbers of the Instruments in respect of which the option has been exercised, and stating the nominal amount of Instruments in respect of which the option is exercised and at the same time, where the

50

	permanent Global Instrument is a CGN, presenting the permanent Global Instrument for notation. Where the Global Instrument is an NGN, the relevant Issuer shall procure that details of such exercise shall be enteredpro ratain the records of the relevant clearing system and the nominal amount of the Notes recorded in those records will be reduced accordingly.
8	NGN nominal amount
	Where the Global Instrument is an NGN, the relevant Issuer shall procure that any exchange, payment, cancellation, exercise of any option or any right under the Instruments, as the case may be, in addition to the circumstances set out above shall be entered in the records of the relevant clearing systems and upon any such entry being made, in respect of payments of principal, the nominal amount of the Instruments represented by such Global Instrument shall be adjusted accordingly.
9	Trustee’s Powers
	In considering the interests of Instrumentholders while any Global Instrument is held on behalf of a clearing system, the Trustee may have regard to any information provided to it by such clearing system or its operator as to the identity (either individually or by category) of its accountholders with entitlements to such Global Instrument and may consider such interests as if such accountholders were the holders of the Instruments represented by such Global Instrument.
10	Events of Default
	Each Global Instrument provides that the Trustee, at its discretion, may, and if so requested by holders of at least one-quarter in nominal amount of the Instruments then outstanding or if so directed by an Extraordinary Resolution, shall cause such Global Instrument, or a portion of it, to become due and repayable in the circumstances described in Condition 9 by stating in the notice to the relevant Issuer the principal amount of such Global Instrument which is becoming due and repayable. If principal in respect of any Instrument is not paid when due, only the Trustee may enforce the rights of the Instrumentholders against such Issuer under the terms of the Trust Deed unless the Trustee, having become bound to proceed, fails to do so within a reasonable time and such failure is continuing.
11	Notices
	So long as any Instruments are represented by a Global Instrument and such Global Instrument is held on behalf of a clearing system, notices to the holders of Instruments of that Series may be given by delivery of the relevant notice to that clearing system for communication by it to entitled accountholders in substitution for publication as required by the Conditions or by delivery of the relevant notice to the holder of the Global Instrument.
12	Partly Paid Instruments
	The provisions relating to Partly Paid Instruments are not set out in this Prospectus, but will be contained in the relevant Final Terms and so in the Global Instruments. While any instalments of the subscription moneys due from the holder of Partly Paid Instruments are overdue, no interest in a Global Instrument representing such Instruments may be exchanged for an interest in a permanent Global Instrument or for Definitive Instruments (as the case may be). If any Instrumentholder fails to pay any instalment due on any Partly Paid Instruments within the time specified, the relevant Issuer may forfeit such Instruments and shall have no further obligation to their holder in respect of them.

51

USE OF PROCEEDS

The net proceeds of the issue of each Series of Instruments will be used by the relevant Issuer for its general corporate purposes. If in respect of any particular issue of Instruments, there is a particular identified use of proceeds, this will be stated in the relevant Final Terms.

DESCRIPTION OF NATIONAL GRID GAS plc

Incorporation and Businesses

National Grid Gas is a licensed gas transporter under the Gas Act 1986, as amended (the “Gas Act”).

National Grid Gas is the parent undertaking of the National Grid Gas Group and is an indirectly wholly-owned subsidiary undertaking of National Grid plc. National Grid Gas is incorporated in England and Wales.

National Grid Gas was incorporated in England and Wales on 1 April 1986 as a public company limited by shares under the Companies Act 1985. The address of National Grid Gas’s registered office is 1-3 Strand, London, WC2N 5EH and the telephone number of the registered office is +44 20 7004 3000.

Business of National Grid Gas plc

The business of National Grid Gas comprises three principal activities:

(i)	owning and operating the high pressure gas national transmission system (“NTS”) in Great Britain, comprising approximately 4,326 miles of high pressure pipe and 26 compressor stations, connecting to eight distribution networks and to third party independent systems for onward transportation of gas to end consumers as well as interconnectors;
(ii)	operating four gas distribution networks (“DNs”), comprising approximately 82,000 miles of distribution pipeline, conveying gas to domestic and industrial/commercial users in central, eastern and north west England, as well as a large part of London and the northern Home Countries;
(iii)	providing regulated gas metering and meter reading services in Great Britain; and
(iv)	owning and operating liquefied natural gas (“LNG”) storage facilities.

National Grid Gas holds a gas transporter licence under the Gas Act in respect of each of its NTS and DN gas transportation activities (i.e. the activities described in (i) and (ii) above) (together, the “Licences”).

National Grid Gas’s customers are gas shippers, for whom it transports gas through the NTS and through its DNs to consumers or through the NTS to other gas transporters’ gas distribution networks for onward conveyance to consumers.

National Grid Gas is responsible for residual energy balancing on the gas transportation system in Great Britain (the “GB system”). This role is given to National Grid Gas under the commercial arrangements governing the GB system (the Uniform Network Code). To facilitate this, the Licences permit National Grid Gas to (and it does) buy gas or rights to use gas systems (including capacity rights) in order to meet anticipated physical requirements for energy balancing on the GB system. In some circumstances National Grid Gas may also sell gas or capacity rights it has bought if it becomes clear that the anticipated physical position will not be required (and may make a profit, or avoid a loss in doing so). The purpose of this activity is not to make a profit, but to balance the GB system (although National Grid Gas’s price control does incentivise it to keep its costs of system operation to a minimum).

Aside from the permitted balancing activities described above, the Licences prohibit National Grid Gas from purchasing or otherwise acquiring gas, gas derivatives or capacity rights in respect of the flow of gas for the purposes of resale or other disposition to third parties. As a result, National Grid Gas is prohibited from (i) engaging in any gas “trading” activity (other than in the very limited circumstances broadly related to the need to balance the GB system as described above) and (ii) acting as a gas shipper or gas supplier.

National Grid Gas is the parent company of National Grid Metering. National Grid Metering primarily provides gas metering services to National Grid Gas for both (i) industrial and commercial, and (ii)

53

domestic customers throughout Great Britain. The provision of gas metering services to National Grid Gas enables National Grid Gas to discharge National Grid Gas’s obligations in the Licences in respect of metering. Following the sale of four gas distribution networks by National Grid Gas in 2005, National Grid Metering provides metering services to those four gas distribution networks to enable them to discharge the obligations contained in their gas transporter licences in respect of metering. National Grid Metering also provides gas meter reading services to gas suppliers.

Regulatory Framework

The supply, transportation and shipping of gas in Great Britain are regulated under the Gas Act. The regimes for gas and electricity are administered in Great Britain by a sectoral regulator, the Gas and Electricity Markets Authority (“GEMA”) through its secretariat, Ofgem which was established by the Utilities Act 2000. In addition, the Health and Safety Executive is responsible for safety-related regulation of the gas transportation and LNG storage businesses.

55

As indicated above, each of the gas transportation businesses of National Grid Gas is operated pursuant to the Licences which were granted (or treated as granted) under the Gas Act.

The Gas Act and the Licences oblige National Grid Gas in respect of each of National Grid Gas’s businesses of:

(i)	the NTS; and
(ii)	the DNs (taken as a whole),

to develop, maintain and operate an economic and efficient pipeline system for the conveyance of gas in Great Britain. These obligations also require National Grid Gas to comply, so far as it is economical for it to do so, with all reasonable requests to connect to the respective systems and convey gas by means of those systems to any premises or other pipeline system. National Grid Gas must also facilitate competition in the supply of gas in Great Britain.

The Licences set out the responsibilities of each business in respect of charging, system access/use of system, metering and other specific obligations required for the proper functioning of the relevant activity and also restrict the revenues which National Grid Gas may derive from its licensed activities (known as the “price controls”). The Licences also require National Grid Gas to conduct each of its transportation businesses in the manner best calculated to secure that neither the NTS/DN (or any affiliate or related undertaking), any gas shipper or supplier nor any other gas transporter operating a distribution network obtains an unfair commercial advantage including, in particular, any advantage from a preferential or discriminatory arrangement.

The Licences can only be amended either in accordance with (i) the procedures contained in the Licences themselves or (ii) the Gas Act. The Licences continue in force until determined by not less than 10 years’ notice in writing given by GEMA (such notice not to be served earlier than 22 August 2011) or otherwise revoked in accordance with the terms of the Licences (such as in the event of financial default).

Each of the Licences contains conditions which have the effect of “ring fencing” each of the NTS and DN businesses. These include:

(i)	prohibiting National Grid Gas from carrying on activities other than those permitted by the Licences;
(ii)	requiring that each business has sufficient managerial and financial resources available to it to conduct the relevant licensed activities;
(iii)	requiring National Grid Gas to maintain an investment grade issuer credit rating;
(iv)	prohibiting National Grid Gas from creating indebtedness or entering into any other obligations (except in limited circumstances) other than on an arm’s length basis on normal commercial terms for one of its permitted purposes;
(v)	prohibiting the creation of “cross-default” obligations; and
(vi)	prohibiting either the NTS or the DN business from giving or receiving any cross-subsidy from any other group business.

If National Grid Gas is in default of any of these “ring fence” obligations, it is prohibited from declaring and paying a dividend. In October 2002, GEMA consented to National Grid Gas making loans to its immediate parent company, National Grid Gas Holdings plc. This consent was renewed by GEMA in May 2005. As a result, National Grid Gas Holdings plc is subject to a number of the “ring fencing” conditions of the Licences as if it were itself the holder of those Licences.

The Licences also contain “business separation” conditions requiring National Grid Gas to maintain appropriate managerial and operational independence of the transportation businesses of the NTS and DN from each other in order to ensure that each business complies with the obligations not to confer any

56

unfair commercial advantage or cross-subsidy on the other. This is backed up by specific requirements on the manner in which the NTS and DN businesses must interact with one another.

The Gas Act provides that GEMA may impose legally enforceable orders or financial penalties on National Grid Gas for contravening conditions of the Licences or contravening a relevant requirement of that Act or the Utilities Act 2000.

The level of revenue which each of the NTS and DN transportation business may receive from the supply of gas transportation services is set out in the price control conditions contained in the respective Licences. These are generally set for a period of five years by GEMA, either with the agreement of National Grid Gas or after referral to the Competition Commission. Each price control is set taking account of, among other things, an assessment of National Grid Gas’s operating costs, capital expenditure, cost of capital and transportation volumes. Details of the price controls currently applicable to National Grid Gas are given below.

Recent Developments

On June 2005, Ofgem announced that certain aspects of National Grid Gas’s metering business were to be investigated by it under the Competition Act 1988. In May 2006, Ofgem issued a statement of objections setting out why it believes National Grid Gas’s conduct is in breach of Chapter II of that legislation. National Grid Gas responded to this and a further statement of objections issued by Ofgem in April 2007 maintaining that, in its view, it was not in breach. However, on 25 February 2008, Ofgem announced it had decided National Grid plc breached Chapter II of the Competition Act 1998 and Article 82 of the EC Treaty and fined it £41.6m. National Grid plc has announced it continues to believe it has not breached competition law and intends to appeal Ofgem’s decision to the Competition Appeal Tribunal.

The price control arrangements for National Grid Gas’s NTS operations put in place in 2002 ceased on 31 March 2007. On 15 January 2007 National Grid Gas accepted in principle Ofgem’s final proposals for the price control to apply to its NTS operations covering the period from 1 April 2007 to 31 March 2012. The key elements of these proposals are a 4.4 per cent. post-tax real rate of return on National Grid Gas’s regulatory asset value, a £824 million baseline five year capital expenditure allowance (in 2004/5 prices) and a £688 million five year operating expenditure allowance (in 2004/5 prices). The amendments to the licence which applies to its NTS operations required to put these final proposals into effect were implemented in part in April 2007, with the remaining elements implemented on 5 September 2007 with retrospective effect from 1 April 2007.

National Grid Gas has also accepted Ofgem’s final proposals for the incentive schemes covering:

(i)	the external costs of its system operation role to apply for one year from 1 April 2007; and
(ii)	the internal costs of system operation to apply for the five years from 1 April 2007.

These proposals have been implemented through licence changes to National Grid Gas’s gas transporter licence in respect of its NTS operations.

Ofgem extended the price control applicable to National Grid Gas’s DNs originally set in 2002 for a further one year until 31 March 2008. The outcome of that formal review was an increase of 11 per cent. in allowed revenues for 2007/08. In addition, the balance between fixed and variable elements has changed, which will reduce the impact that volume changes, including weather, have on this business in 2007/08.

National Grid Gas has also accepted Ofgem’s final proposals for the price control applicable to the DNs for the five years from 1 April 2008. The key elements of these proposals are a 4.94 per cent. post-tax real rate of return on National Grid Gas’s regulatory asset value, a £0.6 billion baseline five year capital expenditure allowance (in 2005/6 prices), a £1.8 billion five year operating expenditure allowance (in 2005/6 prices) and £1.8 billion for its mains replacement activities over the five years. National Grid Gas

57

is working with Ofgem to agree the changes to its licence applicable to its retained gas distribution business to reflect these proposals which will apply from 1 April 2008.

At Ofgem’s request, National Grid Gas has consulted on incentive scheme structures which will apply to its system operation activities from 1 April 2008. Following this consultation process, which ended on 25 January 2008, Ofgem will take into account the results of the consultation in deciding on the final proposals to be put forward, to apply from 1 April 2008.

On 18 January 2008, National Grid Gas accepted Ofgem’s final proposals in respect of the prices its LNG storage business may charge for the provision of certain regulated services including the provision of operating margins services. This will permit these prices to increase in line with inflation. National Grid Gas also derives revenues from the provision of gas storage services to gas shippers at its LNG storage sites, but these services are sold by auction and the prices are not regulated.

National Grid plc announced an updated dividend policy on 31 January 2008. Its current dividend policy is to increase dividends per ordinary share by 7 per cent. per annum until 31 March 2008. The board of National Grid plc intends to recommend a new policy with the following two components: (i) for the current financial year a one-off increase of 15 per cent. over last year’s full year dividend; and (ii) thereafter a targeted increase of 8 per cent. per annum from this enhanced base until 31 March 2012. This will result in a recommended final dividend for the year ending 31 March 2008 of 21.3 pence per ordinary share and a full year dividend of 33 pence per ordinary share.

The following is a summary of the United Kingdom withholding taxation treatment at the date hereof in relation to payments of principal and interest in respect of the Instruments. The comments do not deal with other United Kingdom tax aspects of acquiring, holding or disposing of Instruments. The comments relate only to the position of persons who are absolute beneficial owners of the Instruments. Prospective Instrumentholders should be aware that the particular terms of issue of any series of Instruments as specified in the relevant Final Terms may affect the tax treatment of that and other series of Instruments. The following is a general guide and should be treated with appropriate caution. Instrumentholders who are in any doubt as to their tax position should consult their professional advisers. Instrumentholders who may be liable to taxation in jurisdictions other than the United Kingdom in respect of their acquisition, holding or disposal of the Instruments are particularly advised to consult their professional advisers as to whether they are so liable (and if so under the laws of which jurisdictions), since the following comments relate only to certain United Kingdom taxation aspects of payments in respect of the Instruments. In particular, Instrumentholders should be aware that they may be liable to taxation under the laws of other jurisdictions in relation to payments in respect of the Instruments even if such payments may be made without withholding or deduction for or on account of taxation under the laws of the United Kingdom.

(A)	UK Withholding Tax on UK Source Interest
1.	The Instruments issued by an Issuer which carry a right to interest will constitute “quoted Eurobonds” provided they are and continue to be listed on a recognised stock exchange within the meaning of section 1005 of the Income Tax Act 2007. The London Stock Exchange is a recognised stock exchange for these purposes. Instruments will be treated as listed on the London Stock Exchange if they are included in the Official List by the United Kingdom Listing Authority and are admitted to trading on the London Stock Exchange. Instruments to be traded on a recognised stock exchange outside the United Kingdom will be treated as “listed” on a recognised stock exchange if (and only if) they are admitted to trading on that exchange and they are officially listed, in accordance with provisions corresponding to those generally applicable in European Economic Area Member States, in a country outside the United Kingdom in which there is a recognised stock exchange. Whilst the Instruments are and continue to be quoted Eurobonds, payments of interest by the Issuer on the Instruments may be made without withholding or deduction for or on account of United Kingdom income tax.
2.	In all cases falling outside the exemption described above, interest on the Instruments may fall to be paid under deduction of United Kingdom income tax at the savings rate (currently 20%) subject to such relief as may be available under the provisions of any applicable double taxation treaty or to any other exemption which may apply. However, this withholding will not apply if the relevant interest is paid on Instruments with a maturity date of less than one year from the date of issue and which are not issued under arrangements the effect of which is to render such Instruments part of a borrowing with a total term of a year or more.
(B)	Provision of Information

Instrumentholders should note that where any interest on Instruments is paid to them (or to any person acting on their behalf) by the relevant Issuer or any person in the United Kingdom acting on behalf of such Issuer (a “paying agent”), or is received by any person in the United Kingdom acting on behalf of the relevant Instrumentholder (other than solely by clearing or arranging the clearing of a cheque) (a “collecting agent”), then the relevant Issuer, the paying agent or the collecting agent (as the case may be) may, in certain cases, be required to supply to HM Revenue and Customs details of the payment and certain details relating to the lnstrumentholder (including the Instrumentholder’s name and address). These provisions will apply whether or not the interest has been paid subject to withholding or deduction for or on account of United Kingdom income tax and whether or not the lnstrumentholder is resident in

61

the United Kingdom for United Kingdom taxation purposes. In certain circumstances, the details provided to HM Revenue and Customs may be passed by HM Revenue and Customs to the tax authorities of certain other jurisdictions.

Additionally, persons in the United Kingdom paying amounts due on redemption of any Instruments which constitute deeply discounted securities as defined in Chapter 8 of Part 4 of the Income Tax (Trading and Other Income) Act 2005 to, or receiving such amounts on behalf of, another person, may also be required to comply with the provisions referred to above. However, HM Revenue & Customs published practice indicates that HM Revenue & Customs will not exercise its power to obtain information where such amounts are received on or before 5 April 2008.

Information may also be required to be reported in accordance with regulations made pursuant to the EU Savings Directive (see below).

(C) Payments under the Guarantee

It is possible that payments under the Guarantee in respect of interest on the Instruments (or other amounts due under the Instruments other than repayment of amounts paid for the Instruments) will not be eligible for the exemption from United Kingdom withholding tax described in paragraph (A)1 above. If such payments are not eligible for that exemption, they may fall to be paid under deduction of United Kingdom income tax at the basic rate (currently 22 per cent.) subject to such relief as may be available under the provisions of any applicable double tax treaty or any other relief that may apply. For the purposes of paragraph (B) above (Provision of Information) “interest” and “amounts payable on redemption” should be taken, for practical purposes, as including payments made under the Guarantee in respect of interest on the Instruments and amounts payable on redemption respectively.

(D) Other Rules Relating to United Kingdom Withholding Tax

1.	Instruments may be issued at an issue price of less than 100 per cent. of their principal amount. Any discount element on any such Instruments should not generally be subject to any United Kingdom withholding tax pursuant to the provisions mentioned in A above, but may be subject to reporting requirements as outlined in B above.
2.	Where Instruments are to be, or may fall to be, redeemed at a premium, as opposed to being issued at a discount, then any such element of premium may constitute a payment of interest. Payments of interest are subject to United Kingdom withholding tax and reporting requirements as outlined above.
3.	Where interest has been paid under deduction of United Kingdom income tax, Instrumentholders who are not resident in the United Kingdom may be able to recover all or part of the tax deducted if there is an appropriate provision in any applicable double taxation treaty.
4.	The references to “interest” above mean “interest” as understood in United Kingdom tax law. The statements above do not take any account of any different definitions of “interest” or “principal” which may prevail under any other law or which may be created by the terms and conditions of the Instruments or any related documentation. Instrumentholders should seek their own professional advice, as regards the withholding tax treatment of any payment on the Instruments which does not constitute “interest” or “principal” as those terms are understood in United Kingdom tax law.
5.	The above description of the United Kingdom withholding tax position assumes that there will be no substitution of an Issuer pursuant to Condition 11.3 of the Instruments and does not consider the tax consequences of any such substitution.
(E)	EU Savings Directive

Under EU Council Directive 2003/48/EC on the taxation of savings income, each Member State is required, to provide to the tax authorities of another Member State details of payments of interest or other similar income paid by a person within its jurisdiction to, or collected by such a person for, an

62

individual resident or certain other persons (referred to in this Directive as “residual entities”) established in that other Member State; however, for a transitional period, Austria, Belgium and Luxembourg may instead apply a withholding system in relation to such payments, deducting tax at rates rising over time to 35%. The transitional period is to terminate at the end of the first full fiscal year following agreement by certain non-EU countries to the exchange of information relating to such payments.

A number of non-EU countries, and certain dependent or associated territories of certain Member States, have adopted similar measures (either provision of information or transitional withholding) in relation to payments made by a person within its jurisdiction to or collected by such a person for, an individual resident, or residual entity established, in a Member State. In addition, the Member States have entered into provision of information or transitional withholding arrangements with certain of those dependent or associated territories in relation to payments made by a person in a Member State to, or collected by such a person for, an individual resident, or residual entity established, in one of those territories.

PLAN OF DISTRIBUTION

Summary of Agreement

Subject to the terms and on the conditions contained in an Amended and Restated Dealer Agreement dated 26 February 2008 (as amended or supplemented from time to time) between the Issuers, the Guarantor, the Permanent Dealers and the Arranger (the “Dealer Agreement”), the Instruments will be offered on a continuous basis by each of the Issuers to the Permanent Dealers. However, each of the Issuers has reserved the right to issue Instruments directly on its own behalf to dealers which are not Permanent Dealers. The Instruments may also be issued by each of the Issuers through the Dealers, acting as agents of the relevant Issuer. The Dealer Agreement also provides for Instruments to be issued in syndicated Tranches which are jointly and severally underwritten by two or more Dealers. The commissions in respect of an issue of Instruments on a syndicated basis will be stated in the relevant Final Terms. Each of the Issuers has agreed to indemnify the Dealers against certain liabilities in connection with the offer and sale of the Instruments.

Selling Restrictions

United States

The Instruments have not been and will not be registered under the United States Securities Act of 1933 as amended (the “Securities Act”) and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in certain transactions exempt from the registration requirements of the Securities Act. Terms used in this paragraph have the meanings given to them by Regulation S under the Securities Act.

Instruments in bearer form having a maturity of more than one year are subject to U.S. tax law requirements and may not be offered, sold or delivered within the United States or its possessions or to a U.S. person, except in certain transactions permitted by U.S. tax regulations. Terms used in this paragraph have the meanings given to them by the U.S. Internal Revenue Code and regulations under it.

Each Dealer has agreed that, except as permitted by the Dealer Agreement, it will not offer, sell or deliver the Instruments of any identifiable Tranche, (i) as part of their distribution at any time or (ii) otherwise until 40 days after completion of the distribution of such Tranche as determined, and certified to the relevant Issuer, by the Issuing and Paying Agent, or in the case of Instruments issued on a syndicated basis, the Arranger, within the United States or to, or for the account or benefit of, U.S. persons, and it will have sent to each dealer to which it sells Instruments during the distribution compliance period a confirmation or other notice setting forth the restrictions on offers and sales of the Instruments within the United States or to, or for the account or benefit of, U.S. persons.

In addition, until 40 days after the commencement of the offering, an offer or sale of Instruments within the United States by any dealer (whether or not participating in the offering) may violate the registration requirements of the Securities Act.

Public Offer Selling Restriction Under the Prospectus Directive

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each Dealer has represented and agreed that, with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of Instruments which are the subject of the offering contemplated by this Prospectus as completed by the final terms in relation thereto to the public in that Relevant Member State except that it may, with effect from and including the Relevant Implementation Date, make an offer of such Instruments to the public in that Relevant Member State:

64

(a)	if the final terms in relation to the Instruments specify that an offer of those Instruments may be made other than pursuant to Article 3(2) of the Prospectus Directive in that Relevant Member State (a “Non-exempt Offer”), following the date of publication of a prospectus in relation to such Instruments which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, provided that any such prospectus has subsequently been completed by the final terms contemplating such Non-exempt Offer, in accordance with the Prospectus Directive, in the period beginning and ending on the dates specified in such prospectus or final terms, if applicable;
(b)	at any time to legal entities which are authorised or regulated to operate in the financial markets or, if not so authorised or regulated, whose corporate purpose is solely to invest in securities;
(c)	at any time to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than€43,000,000 and (3) an annual net turnover of more than€50,000,000, as shown in its last annual or consolidated accounts;
(d)	at any time to fewer than 100 natural or legal persons (other than qualified investors as defined in the Prospectus Directive) subject to obtaining the prior consent of the relevant Dealer or Dealers nominated by the Issuer for any such offer; or
(e)	at any time if the denomination per Instrument being offered amounts to at least euro 50,000; or
(f)	at any time in any other circumstances falling within Article 3(2) of the Prospectus Directive,

provided that no such offer of Instruments referred to in (b) to (f) above shall require the Issuer or any Dealer to publish a prospectus pursuant to Article 3 of the Prospectus Directive or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

For the purposes of this provision, the expression an “offer of Instruments to the public” in relation to any Instruments in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Instruments to be offered so as to enable an investor to decide to purchase or subscribe the Instruments, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression “Prospectus Directive” means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

United Kingdom

Each Dealer has represented, warranted and agreed that:

(a)	in relation to any Instruments which have a maturity of less than one year, (i) it is a person whose ordinary activities involve it in acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of its business and (ii) it has not offered or sold and will not offer or sell any Instruments other than to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or as agent) for the purposes of their businesses or who it is reasonable to expect will acquire, hold, manage or dispose of investments (as principal or agent) for the purposes of their businesses where the issue of the Instruments would otherwise constitute a contravention of Section 19 of the FSMA by the Issuer;
(b)	it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) received by it in connection with the issue or sale of any Instruments in circumstances in which Section 21(1) of the FSMA does not apply to the Issuer; and
(c)	it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to any Instruments in, from or otherwise involving the United Kingdom.

65

Japan

The Instruments have not been and will not be registered under the Financial Instruments and Exchange Law of Japan (the “Financial Instruments and Exchange Law”). Accordingly, each of the Dealers has represented, warranted and agreed that it has not, directly or indirectly, offered or sold and will not, directly or indirectly, offer or sell any Instruments in Japan or to, or for the benefit of, any resident of Japan or to others for re-offering or re-sale, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan except pursuant to an exemption from the registration requirements of, and otherwise in compliance with the Financial Instruments and Exchange Law and other relevant laws and regulations of Japan. As used in this paragraph, “resident of Japan” means any person resident in Japan, including any corporation or other entity organised under the laws of Japan.

General

These selling restrictions may be modified by the agreement of the relevant Issuer and the Dealers following a change in a relevant law, regulation or directive. Any such modification will be set out in the Final Terms issued in respect of the issue of Instruments to which it relates or in a supplement to this Prospectus.

No action has been or will be taken in any country or jurisdiction by the relevant Issuers or the Dealers that would permit a public offering of Instruments, or possession or distribution of any offering material in relation thereto, in any country or jurisdiction where action for that purpose is required. Persons into whose hands this Prospectus or any Final Terms comes are required by the Issuers and the Dealers to comply with all applicable laws and regulations in each country or jurisdiction in or from which they purchase, offer, sell or deliver Instruments or have in their possession or distribute such offering material, in all cases at their own expense.

Each Dealer has agreed that it will comply with all relevant laws, regulations and directives in each jurisdiction in which it purchases, offers, sells or delivers Instruments or has in its possession or distributes this Prospectus, any other offering material or any Final Terms and neither the Issuers nor any other Dealer shall have responsibility for such material.
