to the public in a Member State of the European Economic Area
in circumstances which require the publication of a prospectus
under the Prospectus Directive, the minimum denomination shall
be 50,000 (or its equivalent in any other currency as at the
date of issue of the Instruments) and (b) unless otherwise
permitted by then current laws and regulations, Instruments

    The length of the interest periods for the Instruments and the
applicable interest rate or its method of calculation may
differ from time to time or be constant for any Series.
Instruments may have a maximum interest rate, a minimum
interest rate, or both. The use of interest accrual periods
permits the Instruments to bear interest at different rates in
the same interest period. All such information will be set out
in the relevant Final Terms.Redemption
    
    The relevant Final Terms will specify the basis for calculating
the redemption amounts payable, which may be by reference to a
stock index or formula or as otherwise provided in the relevant
Final Terms.Unless permitted by then current laws and regulations,
Instruments which have a maturity of less than one year must
have a minimum redemption amount of £100,000 (or its equivalent
in other currencies).Redemption by Instalments

Instruments, step-up Instruments, step-down Instruments, Dual
Currency Instruments, reverse Dual Currency Instruments,
optional Dual Currency Instruments, Partly Paid Instruments and
any other type of Instrument that the relevant Issuer, the
Trustee and any Dealer or Dealers may agree to issue under the

regulations and directives, will be set out in the relevant
Final Terms and (if applicable) the relevant Supplemental
Prospectus.Optional Redemption
    
    The Final Terms issued in respect of each issue of Instruments
will state whether such Instruments may be redeemed prior to
their stated maturity at the option of the relevant Issuer
(either in whole or in part) and/or the holders, and if so the
terms applicable to such redemption.Status of Instruments and the guarantee
    
    The Instruments (and where applicable, the guarantee in respect
of them) will constitute unsubordinated and unsecured
obligations of the relevant Issuer (and where applicable, the
Guarantor, respectively), all as described in Terms and
Conditions of the Instruments - Status.Negative Pledge
    
    None of the Issuers or the Guarantor will give any negative
pledge in respect of Instruments to be issued under the
Programme.Cross Default

##### 



will not contain any cross default provision in respect of any
other indebtedness of the relevant Issuer or the Guarantor,
where applicable, whether with respect to Instruments in any
other Series or otherwise.Events of Default
    
    The events of default under the Instruments are as specified
below under Terms and Conditions of the Instruments  Events
of Default.Early Redemption

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. In the event that
any deduction or withholding on account of tax is required to
be made, the Issuer will, in the circumstances provided in
Terms and Conditions of the Instruments  Taxation and
subject to the exceptions therein, pay additional amounts so as
to compensate for the amounts withheld or deducted.Governing Law
    
    English.Listing
    
    Each Series may be admitted to the Official List and admitted
to trading on the Market and/or admitted to listing, trading
and/or quotation by any other listing authority, stock exchange
and/or quotation system as may be agreed between the relevant
Issuer and the relevant Dealer(s) and specified in the relevant
Final Terms or may be unlisted.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. 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.Selling Restrictions
    
    United States, United Kingdom, Public Offer Selling Restriction
under the Prospectus Directive (in the case of unlisted
Instruments) and Japan. See Plan of Distribution.Category 2 selling restrictions will apply to the Instruments

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),

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

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. The Terms
and Conditions applicable to each Series will therefore be
those as set out in Terms and Conditions of the Instruments
below as supplemented, modified or replaced by 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.

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 ConventionIf 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 InstrumentsThe 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

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).

interest will accrue by reference to an Index or Formula as specified in the
relevant Final Terms
 (a)
    
    Zero Coupon InstrumentsWhere 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 InstrumentsIn 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 InstrumentsIn 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 InterestInterest 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),

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)
    
    CalculationsThe 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 AmountsAs 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.

by an Indexation Adviser (and approved by the Trustee (acting solely on the advice
of the Indexation Adviser)) or (2) if no such determination is made by such
Indexation Adviser within seven days, the Index Figure last published (or, if later,
the substitute index figure last determined pursuant to Condition 4.3(i)) before the
date for payment.
 4.4
    
    Application of ChangesWhere 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]*

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 ReasonsIf 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).

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 5.5.2
    
    Redemption for Taxation ReasonsIf, 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
    
    PurchasesThe 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

    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 InstrumentsThe 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

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
OptionsIf 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

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 InstrumentsPartly 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 InstalmentsUnless 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
    
    CancellationAll 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.

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

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.

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

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)

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)

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).

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

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 DeedThe 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 and the Couponholders and, if the Trustee so requires, such
modification shall be notified to the Instrumentholders as soon as practicable.11.3
    
    SubstitutionThe 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

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 TrusteeIn 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 TalonsIf 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,

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

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.

    NoticesAll 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

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.
 17 Governing Law and Jurisdiction

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 InstrumentsUpon 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 SystemsEach 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; and1.2
    
    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 InstrumentsEach 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 InstrumentsFor 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 InstrumentsIf 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 entered pro 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 ConditionsThe 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
    
    PaymentsNo 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 be prima 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 entered pro
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
    
    PrescriptionClaims 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
    
    MeetingsThe 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
    
    CancellationCancellation 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
    
    PurchaseInstruments 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 OptionAny 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 OptionsAny 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 entered pro 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 amountWhere 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 PowersIn 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 DefaultEach 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
    
    NoticesSo 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 InstrumentsThe 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 BusinessesNational 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 plcThe 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.

 There are no potential conflicts of interest between the duties to National Grid Gas of each of
the Directors listed above and his private interests or other duties.Regulatory FrameworkThe 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.

##### 



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 DevelopmentsOn 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

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.

UNITED KINGDOM TAXATION
 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 Interest1.
    
    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)

(C)
    
    Payments under the Guarantee
  (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)
