The provisions of Clauses 2.3 (Covenant to Pay), 2.4 (Discharge), 2.5 (Payment after a Default) and 2.6 (Rate of Interest after a Default) and of Clauses 3 (Form of the

|2.3 | Covenant to Pay
|--- | ---------------

The relevant Issuer shall on any date when any Instruments become due to be redeemed, in whole or in part, unconditionally pay to or to the order of the Trustee in the Contractual Currency, in the case of
any Contractual Currency other than euro, in the principal financial centre for the Contractual Currency and, in the case of euro, in a city in which banks have access to the TARGET System, in same day funds the Redemption Amount of the Instruments
becoming due for redemption on that date together with any applicable premium and shall (subject to the Conditions and other than in respect of the Zero Coupon Instruments) until such payment (both before and after judgment) unconditionally so pay
to or to the order of the Trustee interest in respect of the nominal amount of the Instruments outstanding as set out in the Conditions (subject to Clause 2.6 (Rate of Interest after a Default)) provided that (a) payment of any sum due
in respect of the Instruments made to the Issuing and Paying Agent as provided in the Agency Agreement shall, to that extent, satisfy such obligation except to the extent that there is failure in its subsequent payment to the relevant
Instrumentholders or Couponholders under the Conditions and (b) a payment made after the due date or as a result of the Instrument becoming repayable following an Event of Default shall be deemed to have been made when the full amount due has
been received by the Issuing and Paying Agent or the Trustee and notice to that effect has been given to the Instrumentholders (if required under Clause 6.8 (Notice of Late Payment)), except to the extent that there is failure in its
subsequent payment to the relevant Instrumentholders or Couponholders under the Conditions. This covenant shall only have effect each time Instruments are issued and outstanding, when the Trustee shall hold the benefit of this covenant on trust for
the Instrumentholders and Couponholders of the relevant Series.



|2.4 | Discharge
|--- | ---------

Subject to Clause 2.5 (Payment after a Default), any payment to be made in respect of the Instruments or the Coupons by the relevant Issuer, the Guarantor or the Trustee may be made as provided in
the Conditions and any payment so made shall (subject to Clause 2.5 (Payment after a Default)) to that extent be a good discharge to such Issuer, the Guarantor or the Trustee, as the case may be (including, in the case of Instruments
represented by a NGN, whether or not the corresponding entries have been made in the records of Euroclear and Clearstream, Luxembourg), except to the extent that there is failure in its subsequent payment to the relevant Instrumentholders or
Couponholders under the Conditions.



|2.5 | Payment after a Default

| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | to act as Paying Agents of the Trustee under this Trust Deed and the Instruments on the terms of the Agency Agreement (with consequential amendments
as necessary and except that the Trustees liability for the indemnification, remuneration and expenses of the Paying Agents shall be limited to the amounts for the time being held by the Trustee in respect of the Instruments on the terms of
this Trust Deed) and thereafter to hold all Instruments, Coupons and Talons and all moneys, documents and records held by them in respect of Instruments, Coupons and Talons to the order of the Trustee; or

| | (ii) | to deliver all Instruments, Coupons and Talons and all moneys, documents and records held by them in respect of the Instruments, Coupons and Talons
to the Trustee or as the Trustee directs in such notice and,
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.5.2 | by notice in writing to the relevant Issuer and the Guarantor (if applicable), require such Issuer failing whom, the Guarantor (if
applicable) to make all subsequent payments in respect of the Instruments, Coupons and Talons to or to the order of the Trustee and not to the Issuing and Paying Agent and with effect from the receipt of any such notice by such Issuer and the
Guarantor (if applicable), until such notice is withdrawn, the first proviso to Clause 2.3 (Covenant to Pay) shall cease to have effect.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.6 | Rate of Interest after a Default
|--- | --------------------------------

If the Instruments bear interest at a floating or other variable rate and they become immediately payable under the Conditions following an Event of Default, the rate of interest payable in respect of
them shall continue to be calculated by the Calculation Agent in accordance with the Conditions (with consequential amendments as necessary) except that the rates of interest need not be notified to Instrumentholders. The first period in respect of
which interest shall be so calculable shall commence on the expiry of the Interest Period during which the Instruments become so repayable.



|3 | Form of the Instruments
|- | -----------------------



|3.1 | The Global Instruments
|--- | ----------------------

The Instruments shall initially be represented by a temporary Global Instrument or a permanent Global Instrument in the nominal amount of the Tranche being issued. Interests in temporary Global
Instruments shall be exchangeable for Definitive Instruments or interests in permanent Global Instruments as set out in each temporary Global Instrument. Interests in permanent Global Instruments shall be exchangeable for Definitive Instruments as
set out in each permanent Global Instrument.



|3.2 | The Definitive Instruments
|--- | --------------------------

The Definitive Instruments, Coupons and Talons shall be security printed in accordance with applicable legal and stock exchange requirements substantially in the forms set out in Schedule 2. The
Instruments shall be endorsed with the Conditions.



|3.3 | Signature
|--- | ---------

The Instruments, Coupons and Talons shall be signed manually or in facsimile by an authorised signatory of the relevant Issuer and the Instruments shall be authenticated by or on behalf of the Issuing and
Paying Agent. The relevant Issuer may use the facsimile signature of any person who at the date of this Trust Deed is such an authorised signatory even if at the time of issue of any Instruments, Coupons or Talons he no longer holds that office. In
the case of a Global Instrument which is a NGN, the Issuing and Paying Agent shall also instruct the Common Safekeeper to effectuate the same. Instruments, Coupons and Talons so executed and authenticated (and effectuated, if applicable) shall be
binding and valid obligations of the relevant Issuer. Execution in facsimile of any Instruments and



|         
|---------
|A16529343
|8        



---

any photostatic copying or other duplication of any Global Instruments (in unauthenticated form, but executed manually on behalf of the relevant Issuer as stated above) shall be binding upon such
Issuer in the same manner as if such Instruments were signed manually by such signatories.



|3.4 | Title
|--- | -----

The holder of any Instrument, Coupon or Talon shall (save as otherwise required by law) be treated as its absolute owner for all purposes (whether or not it is overdue and regardless of any notice of
ownership, trust or any interest in it, any writing on it or its theft or loss) and no person will be liable for so treating the holder.



|4 | Stamp Duties and Taxes
|- | ----------------------



|4.1 | Stamp Duties
|--- | ------------

Each of the Issuers shall pay any stamp, issue, documentary or other taxes and duties payable in the United Kingdom in respect of the creation, issue and offering of the Instruments, Coupons and Talons by
it and the execution or delivery by it of this Trust Deed. Each Issuer shall also indemnify the Trustee, the Instrumentholders and the Couponholders from and against all stamp, issue, documentary or other taxes paid by any of them in any
jurisdiction in connection with any action taken by or on behalf of the Trustee or, as the case may be (where entitled to do so), the Instrumentholders or the Couponholders to enforce the relevant Issuers or (if applicable) the
Guarantors obligations under this Trust Deed or the Instruments, Coupons or Talons.



|4.2 | Change of Taxing Jurisdiction
|--- | -----------------------------

If an Issuer or the Guarantor becomes subject generally to the taxing jurisdiction of a territory or a taxing authority of or in that territory with power to tax other than or in addition to the United
Kingdom or any such authority of or in such territory then such Issuer or, as the case may be, the Guarantor shall (unless the Trustee otherwise agrees) give the Trustee an undertaking satisfactory to the Trustee in terms corresponding to the terms
of Condition 7 with the substitution for, or (as the case may require) the addition to, the references in that Condition to the United Kingdom of references to that other or additional territory or authority to whose taxing jurisdiction such Issuer
or the Guarantor has become so subject. In such event this Trust Deed and the Instruments, Coupons and Talons shall be read accordingly.



|4A | Guarantee and Indemnity
|-- | -----------------------



|4A.1 | Guarantee
|---- | ---------

The Guarantor unconditionally and irrevocably guarantees that if National Grid Gas Finance (No 1) does not pay any sum payable by it under this Trust Deed, the Instruments or the Coupons by the time and
on the date specified for such payment (whether on the normal due date, on acceleration or otherwise), the Guarantor shall pay that sum to or to the order of the Trustee, in the manner provided in Clause 2.3 (Covenant to Pay) (or if in
respect of sums due under Clause 7 (Remuneration and Indemnification of the Trustee), in pounds sterling (or such other currency as may be agreed between the Issuers, the Guarantor and the Trustee from time to time) in London in immediately
available funds) before close of business on that date in the city to which payment is so to be made.



|         
|---------
|A16529343
|9        



---

Clauses 2.3(a) and 2.3(b) shall apply (with consequential amendments as necessary) to such payments other than those in respect of sums due under Clause 7 (Remuneration and
Indemnification of the Trustee). All payments under the Guarantee by the Guarantor shall be made subject to Condition 6 and Clause 4.2 (Change of Taxing Jurisdiction).



|4A.2 | Guarantor as Principal Debtor
|---- | -----------------------------

As between the Guarantor and the Trustee, the Instrumentholders and the Couponholders but without affecting National Grid Gas Finance (No 1)s obligations, the Guarantor shall be liable under this
Clause as if it were the sole principal debtor and not merely a surety. Accordingly, it shall not be discharged, nor shall its liability be affected, by anything that would not discharge it or affect its liability if it were the sole principal
debtor (including (1) any time, indulgence, waiver or consent at any time given to National Grid Gas Finance (No 1) or any other person, (2) any amendment to any other provisions of this Trust Deed or to the Conditions or to any security
or other guarantee or indemnity, (3) the making or absence of any demand on National Grid Gas Finance (No 1) or any other person for payment, (4) the enforcement or absence of enforcement of this Trust Deed, the Instruments or the Coupons
or of any security or other guarantee or indemnity, (5) the taking, existence or release of any security, guarantee or indemnity, (6) the dissolution, amalgamation, reconstruction or reorganisation of National Grid Gas Finance (No 1) or
any other person or (7) the illegality, invalidity or unenforceability of or any defect in any provision of this Trust Deed, the Instruments or the Coupons or any of National Grid Gas Finance (No 1)s obligations under any of them).



|4A.3 | Guarantors Obligations Continuing
|---- | ----------------------------------

The Guarantors obligations under this Trust Deed are and shall remain in full force and effect by way of continuing
security until no sum remains payable under this Trust Deed, the Instruments or the Coupons. Furthermore, those obligations of the Guarantor are additional to, and not instead of, any security or other guarantee or indemnity at any time existing in
favour of any person, whether from the Guarantor or otherwise and may be enforced without first taking proceedings against National Grid Gas Finance (No 1), any other person, any security or any other guarantee or indemnity.



|4A.4 | Exercise of Guarantors Rights
|---- | ------------------------------

So long as any sum remains payable by National Grid Gas Finance (No 1) under this Trust Deed, the Instruments or the
Coupons:



| | 4A.4.1 | any right of the Guarantor, by reason of the performance of any of its obligations under this Clause, to be indemnified by National Grid Gas
Finance (No 1) or to take the benefit of or to enforce any security or other guarantee or indemnity shall be exercised and enforced by the Guarantor only in such manner and on such terms as the Trustee may require or approve and
| | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4A.4.2 | any amount received or recovered by the Guarantor (a) as a result of any exercise of any such right or (b) in the liquidation,
dissolution, amalgamation, reconstruction, reorganisation, insolvency, winding-up or analogous proceedings relating to National Grid Gas Finance (No 1) shall be held in trust for the Trustee and immediately paid to the Trustee and the Trustee shall
hold it on the trusts set out in Clause 5.1 (Declaration of Trust).

|4A.5 | Suspense Accounts
|---- | -----------------

Any amount received or recovered by the Trustee (otherwise than as a result of a payment by National Grid Gas Finance (No 1) to the Trustee in accordance with Clause 2 (Issue of Instruments and
Covenant to Pay)) in respect of any sum payable by National Grid Gas Finance (No 1) under this Trust Deed, the Instruments or the Coupons may be placed in a suspense account and kept there for so long as the Trustee thinks fit.



|4A.6 | Avoidance of Payments
|---- | ---------------------

The Guarantor shall within 5 business days of demand indemnify the Trustee, each Instrumentholder and each Couponholder against any cost, loss, expense or liability sustained or incurred by it as a result
of it being required for any reason (including any bankruptcy, insolvency, winding-up, dissolution, or similar law of any jurisdiction) to refund all or part of any amount received or recovered by it in respect of any sum payable by National Grid
Gas Finance (No 1) under this Trust Deed, any Instrument or Coupons relating to that Instrument and shall in any event pay to it on demand the amount as refunded by it.



|4A.7 | Debts of National Grid Gas Finance (No 1)
|---- | -----------------------------------------

If any moneys become payable by the Guarantor under this Guarantee, National Grid Gas Finance (No 1) shall not (except in
the event of the liquidation of National Grid Gas Finance (No 1)) so long as any such moneys remain unpaid, pay any moneys for the time being due from National Grid Gas Finance (No 1) to the Guarantor.



|4A.8 | Indemnity
|---- | ---------

As separate, independent and alternative stipulations, the Guarantor unconditionally and irrevocably agrees (1) that any sum that, although expressed to be payable by National Grid Gas Finance (No 1)
under this Trust Deed, the Instruments or Coupons, is for any reason (whether or not now existing and whether or not now known or becoming known to National Grid Gas Finance (No 1), the Guarantor, the Trustee or any Instrumentholder or Couponholder)
not recoverable from the Guarantor on the basis of a guarantee shall nevertheless be recoverable from it as if it were the sole principal debtor and shall be paid by it to the Trustee within 5 business days of demand and (2) as a primary
obligation to indemnify the Trustee, each Instrumentholder and each Couponholder against any loss suffered by it as a result of any sum expressed to be payable by National Grid Gas Finance (No 1) under this Trust Deed, the Instruments or Coupons not
being paid on the date and otherwise in the manner specified in this Trust Deed or any payment obligation of National Grid Gas Finance (No 1) under this Trust Deed, the Instruments or the Coupons being or becoming void, voidable or unenforceable for
any reason (whether or not now existing and whether or not now known or becoming known to the Trustee, any Instrumentholder or any Couponholder), the amount of that loss being the amount expressed to be payable by National Grid Gas Finance (No 1) in
respect of the relevant sum.

|5 | Application of Moneys Received by the Trustee
|- | ---------------------------------------------



|5.1 | Declaration of Trust
|--- | --------------------

All moneys received by the Trustee in respect of the Instruments or amounts payable under this Trust Deed shall, despite any appropriation of all or part of them by the relevant Issuer or the Guarantor
(if applicable), be held by the Trustee on trust to apply them (subject to Clause 5.2 (Accumulation)):



| | 5.1.1 | first, in payment of all costs, charges, expenses and liabilities reasonably incurred by the Trustee (including remuneration payable to it)
in carrying out its functions under this Trust Deed;
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5.1.2 | secondly, in payment of any amounts owing in respect of the Instruments or Coupons pari passu and rateably; and
| | ----- | ---------------------------------------------------------------------------------------------------------------



| | 5.1.3 | thirdly, in payment of any balance to such Issuer for itself or, if any moneys were received from the Guarantor and to the extent of such
moneys, the Guarantor.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------

If the Trustee holds any moneys which represent principal, premium or
interest in respect of Instruments or Coupons which have become void in accordance with the Conditions, the Trustee shall hold them on these trusts.



|5.2 | Accumulation
|--- | ------------

If the amount of the moneys at any time available for payment in respect of the Instruments under Clause 5.1 (Declaration of  Trust) is less than 10 per cent. of the nominal amount of the
Instruments then outstanding, the Trustee may, at its discretion, invest such moneys as provided in Clause 5.3 (Investment). The Trustee may retain such investments and accumulate the resulting income until the investments and the
accumulations, together with any other funds for the time being under its control and available for such payment, amount to at least 10 per cent. of the nominal amount of the Instruments then outstanding and then such investments, accumulations
and funds (after deduction of, or provision for, any applicable taxes) shall be applied as specified in Clause 5.1 (Declaration of Trust).



|5.3 | Investment
|--- | ----------

Moneys held by the Trustee may be invested in its name or under its control in any investments or other assets anywhere, whether or not they produce income, or deposited in its name or under its control
at such bank or other financial institution in such currency as the Trustee may, in its absolute discretion, think fit. If that bank or institution is the Trustee or a subsidiary, parent or associated undertaking of the Trustee, it need only account
for an amount of interest equal to the largest amount of interest payable by it on such a deposit to an independent customer. The Trustee may at any time vary or transpose any such investments or assets or convert any moneys so deposited into any
other currency, and shall not be responsible for any resulting loss, whether by depreciation in value, change in exchange rates or otherwise.



|6 | Covenants
|- | ---------

So long as any Instrument is outstanding, each of the Issuers (in respect of itself only) and the Guarantor shall each:



|6.1 | Books of Account
|--- | ----------------

Keep, and procure that each of its subsidiary undertakings keeps, proper books of account and, at any time after an Event of Default has occurred or if the Trustee reasonably believes that such an event
has occurred, so far as permitted by applicable law, allow, and procure that each such subsidiary undertaking shall allow, the Trustee and anyone appointed by it to whom the relevant Issuer, the Guarantor (if applicable) and/or the relevant
subsidiary undertaking has no reasonable objection, access to its books of account at all reasonable times during normal business hours.

undertaking of it generally in their capacity as such.



|6.5 | Certificate of Directors
|--- | ------------------------

Send to the Trustee, within 14 days of its annual audited financial statements being made available to its members, and also within 21 days of any request by the Trustee a certificate of the relevant
Issuer or, as the case may be, the Guarantor signed by a Director or the Company Secretary that, having made all reasonable enquiries, to the best of the knowledge, information and belief of such Issuer or, as the case may be, the Guarantor as at a
date (the Certification Date) not more than five days before the date of the certificate no Event of Default or Potential Event of Default had occurred (and in the case of a Potential Event of Default was continuing) since the
Certification Date of the last such certificate or (if none) the date of this Trust Deed or, if such an event had occurred (and in the case of a Potential Event of Default was continuing), giving details of it and certifying that it has complied
with its obligations under this Trust Deed or, to the extent that it has failed so to comply, stating such.



|6.6 | Notices to Instrumentholders
|--- | ----------------------------

Obtain the prior written approval of the Trustee to, and promptly give to the Trustee two copies of, the form of every notice given to the Instrumentholders in accordance with Condition 14 (such approval,
unless so expressed, not to constitute approval for the purposes of Section 21 of the Financial Services and Markets Act 2000 any such notice which is a communication within the meaning of that section).



|6.7 | Further Acts
|--- | ------------

So far as permitted by applicable law, do such further things as may be necessary in the reasonable opinion of the Trustee to give effect to this Trust Deed.



|6.8 | Notice of Late Payment

|6.9 | Listing
|--- | -------

If the Instruments are so listed, use all reasonable endeavours to maintain the listing of the Instruments but, if it is unable to do so, having used such endeavours, or if the maintenance of such listing
is agreed by the Trustee to be unduly onerous and the Trustee is satisfied that the interests of the Instrumentholders would not by such action be materially prejudiced, instead use all reasonable endeavours to obtain and maintain a listing of the
Instruments on another stock exchange approved in writing by the Trustee and subject to the requirements of the Dealer Agreement.



|6.10 | Change in Agents
|---- | ----------------

Give at least 14 days prior notice to the Instrumentholders in accordance with the Conditions of any future appointment, resignation or removal of an Agent or of any change by an Agent of its

any amendment to this Trust Deed;
| | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.11.2 | unless the relevant Issuer has notified the Dealers and the Trustee in writing that it does not intend to issue Instruments under the
Programme for the time being, from legal advisers, reasonably acceptable to the Trustee as to such law as may reasonably be requested by the Trustee and in such form and with such content as the Trustee may require, on such occasions as the Trustee
so requests on the basis that the Trustee considers it prudent in view of a change (or proposed change) in (or in the interpretation or application of) any applicable law, regulation or circumstance materially affecting the relevant Issuer, the
Guarantor (if applicable), the Trustee, the Instruments, the Certificates, the Coupons, the Talons, this Trust Deed or the Agency Agreement; and
| | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.11.3 | on each occasion on which a legal opinion is given to any Dealer pursuant to the Dealer Agreement from the legal adviser giving such opinion.
| | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------



|6.12 | Instruments Held by an Issuer or Guarantor etc.

|---- | --------------------------

Provide the Trustee promptly with copies of all supplements and/or amendments to, and/or restatements of, the Dealer Agreement.



|7 | Remuneration and Indemnification of the Trustee
|- | -----------------------------------------------



|7.1 | Normal Remuneration
|--- | -------------------

So long as any Instrument is outstanding each of the Issuers (failing whom, the Guarantor, in the case of Instruments issued by National Grid Gas Finance (No 1)) shall pay the Trustee as remuneration for
its services as Trustee such sum on such dates in each case as they may from time to time agree. Such remuneration shall accrue from day to day from the date of this Trust Deed. However, if any payment to an Instrumentholder or Couponholder of
moneys due in respect of any Instrument or Coupon is improperly withheld or refused, such remuneration shall again accrue as from the date of such withholding or refusal until payment to such Instrumentholder or Couponholder is duly made.



|7.2 | Extra Remuneration
|--- | ------------------

In the event of the occurrence of an Event of Default or Potential Event of Default the Issuer (failing whom the Guarantor) hereby agrees that the Trustee shall be entitled to be paid additional
remuneration, which may be calculated using the Trustees normal hourly rates in force from time to time. In any other case if the Trustee finds it expedient or necessary or is requested by an Issuer to undertake duties that they both agree to
be of an exceptional nature or otherwise outside the scope of the Trustees normal duties under this Trust Deed, such Issuer (failing whom, the Guarantor, in the case of Instruments issued by National Grid Gas Finance (No 1)) shall pay such
additional remuneration as they may agree or, failing agreement as to any of the matters in this Clause 7 (or as to such sums referred to in Clause 7.1 (Normal Remuneration)), as determined by an investment bank (acting as an expert) selected
by the Trustee and approved by such Issuer or, failing such approval, nominated by the President for the time being of The Law Society of England and Wales. The expenses involved in such nomination and such investment banks fee shall be shared
equally between the Trustee and the relevant Issuer. The determination of such investment bank shall be conclusive and binding on the relevant Issuer, the Guarantor, the Trustee, the Instrumentholders and the Couponholders.



|7.3 | Expenses
|--- | --------

Each of the Issuers, in respect of Instruments issued by it, (failing whom, the Guarantor, in the case of Instruments issued by National Grid Gas Finance (No 1)) shall also on demand by the Trustee pay or
discharge all costs, charges, liabilities and expenses reasonably incurred by the Trustee in the preparation and execution of this Trust Deed and the performance of its functions under this Trust Deed including, but not limited to, legal and
travelling expenses and any United Kingdom stamp, documentary or other taxes or duties paid by the Trustee in connection with any legal proceedings reasonably brought or contemplated by the Trustee against an Issuer or the Guarantor to enforce any
provision of this Trust Deed, the Instruments, the Coupons or the Talons and in addition shall pay to the Trustee (if required) an amount equal to the amount of any value added tax or similar tax chargeable in respect of the Trustees
remuneration under this Trust Deed. Such costs, charges, liabilities and expenses shall:

|---------
|A16529343
|15       



---

| | 7.3.1 | in the case of payments made by the Trustee before such demand, carry interest from the date specified in the demand at the rate of the
Trustees cost of funding on the date on which the Trustee made such payments; and
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7.3.2 | in other cases, carry interest at such rate from 30 days after the date of the demand or (where the demand specifies that payment is to be
made on an earlier date) from such earlier date provided that in such event no such interest shall accrue unless payment is actually made on such earlier date.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7.4 | Notice of Costs
|--- | ---------------

The Trustee shall wherever practicable give prior notice to the Issuers and the Guarantor of any costs, charges and expenses properly to be incurred and of payments to be made by the Trustee in the lawful
exercise of its powers under this Trust Deed so as to afford each of the Issuers and the Guarantor a reasonable opportunity to meet such costs, charges and expenses itself or to put the Trustee in funds to make payment of such costs, charges and
expenses. However, failure of the Trustee to give any such prior notice shall not prejudice its rights to reimbursement of such costs, charges and expenses under this Clause 7.



|7.5 | Indemnity

any committee or body of holders of any securities of any such person in each case with the same rights as it would have had if the Trustee were not acting as Trustee and need not account for any profit.

| | (iii) | if any two Directors of the Substituted Obligor certify that it will be solvent immediately after such substitution, the Trustee need not have

---

|13.2 | Retirement and Removal
|---- | ----------------------

Any Trustee may retire at any time on giving at least three months written notice to each of the Issuers and the Guarantor without giving any reason or being responsible for any costs occasioned by
such retirement and the Instrumentholders may by Extraordinary Resolution remove any Trustee provided that the retirement or removal of a sole trust corporation shall not be effective until a trust corporation is appointed as successor Trustee. If a
sole trust corporation gives notice of retirement or an Extraordinary Resolution is passed for its removal, it shall use all reasonable endeavours to procure that another trust corporation is appointed as Trustee.



|13.3 | Co-Trustees
|---- | -----------

The Trustee may, despite Clause 13.1 (Appointment), by written notice to each of the Issuers and the Guarantor appoint anyone to act either as a separate Trustee in respect of any Issue or as an
additional Trustee jointly with the Trustee:



| | 13.3.1 | if the Trustee considers the appointment to be in the interests of the Instrumentholders and/or the Couponholders;
| | ------ | ------------------------------------------------------------------------------------------------------------------



| | 13.3.2 | to conform with a legal requirement, restriction or condition in a jurisdiction in which a particular act is to be performed; or
| | ------ | --------------------------------------------------------------------------------------------------------------------------------



| | 13.3.3 | to obtain a judgment or to enforce a judgment or any provision of this Trust Deed in any jurisdiction.
| | ------ | ------------------------------------------------------------------------------------------------------

Subject to the provisions of this Trust Deed the Trustee may, in the instrument of appointment, confer on any person so
appointed such functions as it thinks fit. The Trustee may by written notice to each of the Issuers, the Guarantor and that person remove that person. At the Trustees request, each Issuer and the Guarantor shall forthwith do all things as may
be required to perfect such appointment or removal and it irrevocably appoints the Trustee as its attorney in its name and on its behalf to do so.

Before appointing such person to act as separate Trustee or additional Trustee the Trustee shall (unless it is not, in the opinion of the Trustee, reasonably practicable to do so) give notice to each of
the Issuers and the Guarantor of its intention to make such appointment (and the reason for that) and shall give due consideration to representations made by each of the Issuers and the Guarantor concerning such appointment. Where, as a result of
this provision, not all the Instruments have the same Trustee, the provisions of this Trust Deed shall apply in respect of each such Trustee as if each were named as a party to this Trust Deed.



|13.4 | Competence of a Majority of Trustees
|---- | ------------------------------------

If there are more than two Trustees the majority of them shall be competent to perform the Trustees functions
provided the majority includes a trust corporation.

|-- | ------------------------------------------------------



|14.1 | Instruments Held in Clearing Systems
|---- | ------------------------------------

So long as any Global Instrument is held on behalf of a clearing system, in considering the interests of
Instrumentholders, 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 or participants with entitlements to any such
Global Instrument and may consider such interests on the basis that such accountholders or participants were the holder(s) of such Global Instrument.



|14.2 | Reliance on Instruments Held in Clearing Systems
|---- | ------------------------------------------------

The Trustee and any Issuer may call for and, except in the case of manifest error, shall be at liberty to accept and place
full reliance on as sufficient evidence thereof any certificate, letter of confirmation or other document issued on behalf of Euroclear or Clearstream, Luxembourg or any form of record made by any of them or such other evidence and/or information
and/or certification as it shall, in its absolute discretion, think fit to the effect that at any particular time or throughout any particular period any particular person is, was, or will be, shown in its records as the holder of a particular
nominal amount of Instruments represented by a Global Instrument and if the Trustee or any Issuer does so rely, such letter of confirmation, form of record, evidence, information or certification shall be conclusive and binding on all concerned for
all purposes. Any such certificate 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 Creation Online system) in
accordance with its usual procedures and in which the holder of a particular nominal amount of Instruments is clearly identified together with the amount of such holding. Neither an Issuer nor the Trustee shall 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 or Clearstream, Luxembourg and subsequently found to be forged or not authentic.



|14.3 | Couponholders
|---- | -------------

No notices need be given to Couponholders. They shall be deemed to have notice of the contents of any notice given to Instrumentholders. Even if it has express notice to the contrary, in exercising any of

Coupons, including damages.

An amount received or recovered in a currency other than the Contractual Currency (whether as a result of, or of the enforcement of, a judgment or order of a court of any jurisdiction, in the insolvency,
winding-up or dissolution of any of the Issuers or the Guarantor or otherwise), by the Trustee or any Instrumentholder or Couponholder in



|

---

respect of any sum expressed to be due to it from the relevant Issuer or the Guarantor, shall only discharge such Issuer or the Guarantor to the extent of the Contractual Currency amount which
the recipient is able to purchase with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable
to do so).



|15.3 | Indemnity
|---- | ---------

If that Contractual Currency amount is less than the Contractual Currency amount expressed to be due to the recipient under this Trust Deed, the Instruments or the Coupons, the relevant Issuer shall
indemnify it against any loss sustained by it as a result. In any event, the relevant Issuer shall indemnify the recipient against the cost of making any such purchase.



|15.4 | Indemnity Separate
|---- | ------------------

The indemnities in this Clause 15 and in Clause 7.5 (Indemnity) constitute separate and independent obligations from the other obligations in this Trust Deed, shall give rise to a separate and
independent course of action, shall apply irrespective of any indulgence granted by the Trustee and/or any Instrumentholder or Couponholder and shall continue in full force and effect despite any judgment, order, claim or proof for a liquidated
amount in respect of any sum due under this Trust Deed, the Instruments and/or the Coupons or any other judgment or order.



|16 | Enforcement
|-- | -----------



|16.1 | Trustee to enforce
|---- | ------------------

Only the Trustee may enforce the rights of the Instrumentholders and Couponholders against the relevant Issuer or the Guarantor, whether the same arise under the general law, this Trust Deed, the
Instruments, the Coupons or otherwise, and no Instrumentholder or Couponholder shall be entitled to proceed directly against the relevant Issuer or the Guarantor unless the Trustee, having become bound to proceed, fails to do so within a reasonable
time and such failure is continuing.



|16.2 | Trustees Indemnity
|---- | -------------------

The Trustee shall not be bound to take any steps to enforce the performance of any provisions of this Trust Deed, the Instruments or the Coupons unless it shall be indemnified and/or secured and/or
prefunded by the Instrumentholders and/or Couponholders to its satisfaction against all proceedings, claims and demands to which it may be liable and against all costs, charges, liabilities and expenses which may be incurred by it in connection with
such enforcement, including the cost of its managements time and/or other internal resources, calculated using its normal hourly rates in force from time to time.

If the Trustee (or any Instrumentholder or Couponholder where entitled in accordance with this Trust Deed so to do) institutes legal proceedings against any of the Issuers or the Guarantor to enforce any
obligations under this Trust Deed:



| | 16.3.1 | proof in such proceedings that as regards any specified Instrument such Issuer or the Guarantor, as the case may be, has made default in
paying any principal or interest due to the relevant Instrumentholder shall (unless the contrary be proved) be sufficient evidence that such Issuer or the Guarantor, as the case may be, has made the same default as regards all other Instruments
which are then repayable or, as the case may be, in respect of which interest is then payable; and
| | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

provisions of Part A of the Final Terms or(b) these terms and conditions as so completed (and subject to simplification by the dis-application of non-applicable provisions), shall be endorsed on such Instruments. 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

the form of the Definitive Instruments, Coupons and Talons referred to below. An Amended and Restated Agency Agreement (as amended or supplemented from time to time, the Agency Agreement) dated 27 March 2013 has been entered
into in relation to the Instruments between the Issuers, the Guarantor, the Trustee, The Bank of New York Mellon as initial issuing and paying agent and the other agent(s) named in it. The issuing and paying agent, the paying agent(s) and the
calculation agent(s) for the time being (if any) are referred to below respectively as the Issuing and Paying Agent, the Paying Agents (which expression shall include the Issuing and Paying Agent) and the
Calculation Agent(s). Copies of the Trust Deed and the Agency Agreement are available for inspection during usual business hours at the registered office of the Trustee (as at 27 March 2013 at Fifth Floor, 100 Wood Street,

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

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

| | (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) | 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).



| | (c) | Margin, Maximum/Minimum Rates of Interest, Redemption Amounts and Rounding
| | --- | --------------------------------------------------------------------------



| | (i) | If any Margin 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, subject always to the next paragraph.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | If any Maximum or Minimum Rate of Interest or Maximum or Minimum Redemption Amount is specified in the relevant Final Terms, then any Rate of

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.



| | (e) | Determination and Publication of Rates of Interest, Interest Amounts, Final Redemption Amounts, Early Redemption Amounts and Optional Redemption
Amounts
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------

The Calculation Agent shall, 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, determine such rate and calculate the Interest
Amounts for the relevant Interest Accrual Period, calculate the Redemption 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 or Optional Redemption 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.



| | (f) | 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, 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. In doing so, the Trustee shall apply the preceding provisions of this Condition, with any necessary consequential amendments, to the extent that, in its opinion, it can do so, and, in all other respects it shall
do so in such manner as it shall deem fair and reasonable in all the circumstances. The Trustee shall have no liability to any person in connection with any determination or calculation it is required to make pursuant to this Condition 3.2.4(f).

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 on which
such payment is due (the date for payment), the Index Figure applicable to the month in which the date for payment falls shall be (1) such substitute index figure (if any) as the Trustee considers (acting solely on the advice
of the Indexation Adviser) to have been published by the United Kingdom Debt Management Office or the Bank of England, as the case may be, for the purposes of indexation of payments on the Reference Gilt or, failing such publication, on any one or
more issues of index-linked Treasury Stock selected 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.

| | (iii) | Delay in publication of Index if sub-paragraph (ii) and/or (iii) of the definition of Index Figure is applicable: If the Index Figure
relating to any month (the calculation month) which is required to be taken into account for the purposes of the determination of the Index Figure for any date is not published on or before the fourteenth business day before the
date on which such payment is due (the date for payment), the Index Figure applicable for the relevant calculation month shall be (1) such substitute index figure (if any) as the Trustee considers (acting solely on the advice
of the Indexation Adviser) to have been published by the United Kingdom Debt Management Office or the Bank of England, as the case may be, for the purposes of indexation of payments on the Reference Gilt or, failing such publication, on any one or
more issues of index-linked Treasury Stock selected 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

| | 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 | Material Changes to or Cessation of the Index
| | --- | ---------------------------------------------



| | (i) | Material changes to the Index: If notice is published by Her Majestys Treasury, or on its behalf, following a change to the coverage or the
basic calculation of the Index, then the Calculation Agent shall make any such adjustments to the Index consistent with any adjustments made to the index as applied to the Reference Gilt.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Cessation of the Index; If the Trustee and the Issuer [and the Guarantor]* have been notified by the Calculation Agent that the Index has ceased to
be published, or if. Her Majestys Treasury, or a person acting on its behalf, announces that it will no longer continue to publish the Index, then the Calculation Agent shall determine a successor index in lieu of any previously applicable
index (the Successor Index) by using the following methodology:
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | if at any time a successor index has been designated by Her Majestys Treasury in respect of the Reference Gilt, such successor index shall be
designated the Successor Index for the purposes of all subsequent Interest Payment Dates, notwithstanding that any other Successor Index may previously have been determined under paragraphs (b) or (c) below; or
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | if a Successor Index has not been determined under paragraph (a) above, the lssuer [, 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 lssuer[; 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

| | (c) | if the lssuer[, 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 (ii); a bank or other person in London shall be appointed by the lssuer[, the

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 lssuer [, 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. 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 lssuer[, the Guarantor]* and the Trustee in connection with such appointment shall be borne by the lssuer[ or the Guarantor]*.



| | (iii) | Adjustment or replacement: The Index shall be adjusted or replaced by a substitute index 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 lssuer,[ 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 or adjustment.

| | 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 designated by Her Majestys Treasury in respect of the Reference Gilt 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 (or such other notice period as may be specified in the relevant Final Terms) 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).



| | 4.7 | HICP
| | --- | ----

Where HICP (as defined below) is specified as the Index or Index Level (each as defined below) in the relevant Final Terms, Conditions 4.7 to 4.10 will apply. For the purposes of Conditions 4.7 to 4.10,
unless the context otherwise requires, the following defined terms shall have the following meanings:

Base Index Level means the base index level as specified in the relevant Final Terms;

Index or Index Level means (subject as provided in Condition 4.9) the non-revised

Union excluding tobacco, expressed as an index and published by Eurostat (the HICP). The first publication or announcement of a level of such index for a calculation month (as
defined in Condition 4.9(i)) shall be final and conclusive and later revisions to the level for such calculation month will not be used in any calculations. Any reference to the Index Level which is specified in these Conditions as applicable to any
day (d) in any month (m) shall, subject as provided in Condition 4.9, be calculated as follows:



LOGO

where:

ldis the Index Level for the day d

HICP m-2 is the level of HICP for month m-2

HICP
m-3 is the level of HICP for month m-3

nbd is the actual number of days from and excluding the first
day of month m to but including day d; and

qmis the actual number of days in month m,

provided that if Condition 4.9 applies, the Index Level shall be the Substitute Index Level determined in accordance with
such Condition.

Index Business Day means a day on which the TARGET System is operating;

Index Determination Date means in respect of any date for which the Index Level is required
to be determined, the fifth Index Business Day prior to such date;

Index Ratio applicable
to any date means the Index Level applicable to the relevant Index Determination Date divided by the Base Index Level and rounded to the nearest fifth decimal place, 0.000005 being rounded upwards; and

Related Instrument means an inflation-linked bond selected by the Calculation Agent that is a debt
obligation of one of the governments (but not any government agency) of France, Italy, Germany or Spain and which pays a coupon or redemption amount which is calculated by reference to the level of inflation in the European Monetary Union with a
maturity date which falls on (a) the same day as the Maturity Date, (b) the next longest maturity date after the Maturity Date if there is no such bond maturing on the Maturity Date, or (c) the next shortest maturity before the
Maturity Date if no bond defined in (a) or (b) is selected by the Calculation Agent. The Calculation Agent will select the Related Instrument from such of those inflation-linked bonds issued on or before the relevant Issue Date and, if
there is more than one such inflation-linked bond maturing on the same date, the Related Instrument shall be selected by the Calculation Agent from such of those bonds. If the Related Instrument is redeemed, the Calculation Agent will select a new
Related Instrument on the same basis, but selected from all eligible bonds in issue at the time the originally selected Related Instrument is redeemed (including any bond for which the redeemed originally selected Related Instrument is exchanged).



| | 4.8 | Application of the Index Ratio
| | --- | ------------------------------

Each payment of interest and principal in respect of the Instruments shall be the amount provided in, or determined in accordance with, these Conditions, multiplied by the Index Ratio applicable to the
date on which such payment falls to be made and rounded in accordance with Condition 3.2.4(c).

| | 4.9 | Changes in Circumstances Affecting the Index
| | --- | --------------------------------------------



| | (i) | Delay in publication of Index:
| | --- | ------------------------------



| | (a) | If the Index Level relating to any month (the calculation month) which is required to be taken into account for the purposes of
the determination of the Index Level for any date (the Relevant Level) has not been published or announced by the day that is five Business Days before the date on which such payment is due (the Affected Payment
Date), the Calculation Agent shall determine a Substitute Index Level (as defined below) (in place of such Relevant Level) by using the following methodology:
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (1) | if applicable, the Calculation Agent will take the same action to determine the Substitute Index Level for the Affected Payment Date as that taken
by the calculation agent (or any other party performing the function of a calculation agent (whatever such partys title)) pursuant to the terms and conditions of the Related Instrument;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | if (1) above does not result in a Substitute Index Level for the Affected Payment Date for any reason, then the Calculation Agent shall
determine the Substitute Index Level as follows:
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Substitute Index Level = Base Level x
(Latest Level / Reference Level) where:

Base Level means the level of the Index (excluding
any flash estimates) published or announced by Eurostat (or any successor entity which publishes such index) in respect of the month which is 12 calendar months prior to the month for which the Substitute Index Level is being determined;

Latest Level means the latest level of the Index (excluding any flash estimates) published or
announced by Eurostat (or any successor entity which publishes such index) prior to the month in respect of which the Substitute Index Level is being calculated; and

Reference Level means the level of the Index (excluding any flash estimates) published or announced by
Eurostat (or any successor entity which publishes such index) in respect of the month that is 12 calendar months prior to the month referred to in Latest Level above.



| | (b) | If a Relevant Level is published or announced at any time after the day that is five Business Days prior to the next Interest Payment Date, such
Relevant Level will not be used in any calculations. The Substitute Index Level so determined pursuant to this Condition 4.9(i) will be the definitive level for that calculation month.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Cessation of publication: If the Index Level has not been published or announced for two consecutive months or Eurostat announces that it will no
longer continue to publish or announce the Index, then the Calculation Agent shall determine a successor index in lieu of any previously applicable Index (the Successor Index) by using the following methodology:
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | if at any time (other than after an Early Termination Event (as defined below) has been designated by the Calculation Agent pursuant to paragraph
(e) below) a successor index has been designated by the calculation agent (or any other party performing the function of a calculation agent (whatever such
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

partys title)) pursuant to the terms and conditions of the Related
Instrument, such successor index shall be designated the Successor Index for the purposes of all subsequent Interest Payment Dates, notwithstanding that any other Successor Index may previously have been determined under
paragraphs (b), (c) or (d) below; or



| | (b) | if a Successor Index has not been determined under paragraph (a) above (and there has been no designation of an Early Termination Event
pursuant to paragraph (e) below), and a notice has been given or an announcement has been made by Eurostat (or any successor entity which publishes such index) specifying that the Index will be superseded by a replacement index specified by
Eurostat (or any such successor), and the Calculation Agent determines that such replacement index is calculated using the same or substantially similar formula or method of calculation as used in the calculation of the previously applicable Index,
such replacement index shall be the Index from the date that such replacement index comes into effect; or
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | if a Successor Index has not been determined under paragraphs (a) or (b) above (and there has been no designation of an Early Termination
Event pursuant to paragraph (e) below), the Calculation Agent shall ask five leading independent dealers to state what the replacement index for the Index should be. If between four and five responses are received, and of those four or five
responses, three or more leading independent dealers state the same index, this index will be deemed the Successor Index. If three responses are received, and two or more leading independent dealers state the same index, this
index will be deemed the Successor Index. If fewer than three responses are received, the Calculation Agent will proceed to paragraph (d) below;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | if no Successor Index has been determined under paragraphs (a), (b) or (c) above on or before the fifth Index Business Day prior to the
next Affected Payment Date the Calculation Agent will determine an appropriate alternative index for such Affected Payment Date, and such index will be deemed the Successor Index;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | if the Calculation Agent determines that there is no appropriate alternative index, the Issuer and the Instrumentholders shall, in conjunction with
the Calculation Agent, determine an appropriate alternative index. If the Issuer and the Instrumentholders, in conjunction with the Calculation Agent, do not reach agreement on an appropriate alternative index within a period of ten Business Days,
then an Early Termination Event will be deemed to have occurred and the Issuer will redeem the Instruments pursuant to Condition 4.10.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Rebasing of the Index: If the Calculation Agent determines that the Index has been or will be rebased at any time, the Index as so rebased (the
Rebased Index) will be used for the purposes of determining each relevant Index Level from the date of such rebasing; provided, however, that the Calculation Agent shall make such adjustments as are made by the calculation agent
(or any other party performing the function of a calculation agent (whatever such partys title)) pursuant to the terms and conditions of the Related Instrument to the levels of the Rebased Index so that the Rebased Index levels reflect the
same rate of inflation as the Index before it was rebased. Any such rebasing shall not affect any prior payments made.

---

| | (iv) | Material Modification Prior to Interest Payment Date: If, on or prior to the day that is five Business Days before an Interest Payment Date,
Eurostat announces that it will make a material change to the Index then the Calculation Agent shall make any such adjustments to the Index consistent with adjustments made to the Related Instrument.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | Manifest Error in Publication: If, within thirty days of publication, the Calculation Agent determines that Eurostat (or any successor entity which
publishes such index) has corrected the level of the Index to remedy a manifest error in its original publication, the Calculation Agent will notify the parties of (A) that correction, (B) the amount that is payable as a result of that
correction and (C) take such other action as it may deem necessary to give effect to such correction.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.10 | Redemption for Index Reasons
| | ---- | ----------------------------

If an Early Termination Event as described under Condition 4.9(ii)(e) is deemed to have occurred, the Issuer will, upon giving not more than 60 nor less than 30 days notice to the Instrumentholders
(or such other notice period as may be specified in the relevant Final Terms) 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 4.8).



|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 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 Reasons
| | --- | -------------------------------

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 subdivision of the United Kingdom or taxing authority in the United Kingdom or any political subdivision of the United Kingdom or in the 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, as 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 (or such other notice period as may be specified in the
relevant Final Terms) 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 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 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 (both before and after 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
| | --- | -----------------------------------------------------------------------



| | 5.5.1 | Residual Holding Call Option
| | ----- | ----------------------------

If (i) Residual Holding Call Option is specified in the relevant Final Terms as applicable, and
(ii) if at any time the Residual Holding Percentage or more of the aggregate nominal amount of Instruments originally issued shall have been redeemed or purchased and cancelled, the Issuer shall have the option to redeem such outstanding
Instruments in whole, but not in part, at their Residual Holding Redemption Amount. Unless otherwise specified in the relevant Final Terms, the Residual Holding Redemption Amount will be calculated by the Calculation Agent by discounting the
outstanding nominal amount of the Instruments and the remaining interest payments (if applicable) to the Maturity Date by a rate per annum (expressed as a percentage to the nearest one hundred thousandth of a percentage point (with halves being
rounded up)) equal to the Benchmark Yield, being the yield on the Benchmark Security at the close of business on the third Business Day prior to the date fixed for such redemption, plus the Benchmark Spread. Where the specified calculation is to be
made for a period of less than one year, it shall be calculated using the Benchmark Day Count Fraction. The Issuer will give not less than 15 nor more than 30 days1irrevocable notice to the Instrumentholders and the Trustee of any such redemption pursuant to this Condition 5.5.1.



| | 5.5.2 | Call Option
| | ----- | -----------

If Call Option is specified in the relevant Final Terms as applicable, 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) permitted to be redeemed specified in the relevant Final Terms and no greater than the maximum nominal amount (if any) permitted to be redeemed specified on this Instrument.

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

Redemption Date(s) (as specified in the relevant Final Terms) at its Optional Redemption Amount (as specified in the relevant Final Terms) together with interest accrued to the date fixed for redemption.

To exercise such option (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

or on behalf of the Issuer [, the Guarantor]* or any of [its/their] subsidiary undertakings may, at the option of the Issuer, be held, resold or surrendered together with all unmatured Coupons and all unexchanged Talons attached to them to a Paying
Agent for cancellation. Any Instruments so purchased or otherwise acquired, for so long as they are 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, Instruments (in the case of all other payments of

| | --- | -----------------------------

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 EC.OFIN 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

| | 6.5.2 | 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.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.5.3 | 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 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.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.5.4 | 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 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:



| | (i) | (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 (which in the case of Australian dollars is Sydney); or
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | (in the case of a payment in euro), which is a TARGET Business Day.
| | ---- | -------------------------------------------------------------------



| | 6.7 | Talons

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 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 or, as the case may be, the Couponholders of the amounts which would otherwise have been receivable in respect of the

Instruments or Coupons had no withholding or deduction been made, except that no such additional amounts shall be payable in respect of any Instrument 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 or Coupon by reason of his having some connection
with the United Kingdom other than the mere holding of such Instrument 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 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 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 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, 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 or pursuant to Condition 6 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.

the case of interest) from the appropriate Relevant Date in respect of them.

|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

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
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|10 | Enforcement
|-- | -----------

Instruments outstanding; and

| | (b) | it has been indemnified to its satisfaction.

|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 or any date for payment of interest on the
Instruments, (ii) to reduce or cancel the nominal 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

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 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 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, Coupons and Talons
|-- | ----------------------------------------------

If an Instrument, 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 lssuer[ 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, 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 lssuer[ or the Guarantor]* on demand the amount payable by the
lssuer[ or the Guarantor]* in respect of such Instruments, Coupons or further Coupons) and otherwise as the lssuer[ or the Guarantor]* may require. Mutilated or defaced Instruments, 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.

|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 lssuer[, 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 any non-contractual obligations arising out of or in connection with them shall be governed by, and 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] lssuer[, 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.

|9.6 | appoint a named person (a proxy) to vote at that meeting in respect of those Instruments and in accordance with that list.
|--- | ----------------------------------------------------------------------------------------------------------------------------

A proxy need not be an Instrumentholder.



|10 | Once a Paying Agent has issued a block voting instruction for a meeting in respect of the votes attributable to any Instruments:
|-- | --------------------------------------------------------------------------------------------------------------------------------



|10.1 | it shall not release the Instruments, except as provided in paragraph 11, until the meeting has been concluded; and

|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12 | Each block voting instruction shall be deposited at least 24 hours before the time fixed for the meeting at such place as the Trustee shall
designate or approve, and in default it shall not be valid unless the chairman of the meeting decides otherwise before the meeting proceeds to business. If the Trustee requires, a notarially certified copy of each block voting instruction shall be
produced by the proxy at the meeting but the Trustee need not investigate or be concerned with the validity of the proxys appointment.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|13 | A vote cast in accordance with a block voting instruction shall be valid even if it or any of the Instrumentholders instructions
pursuant to which it was executed has previously been revoked or amended, unless written intimation of such revocation or amendment is received from the relevant Paying Agent by the relevant Issuer or the Trustee at its registered office or by the
chairman of the meeting in each case at least 24 hours before the time fixed for the meeting.

|19 | The chairman, may with the consent of (and shall if directed by) a meeting, adjourn the meeting from time to time and from place to place.
Only business which could have been transacted at the original meeting may be transacted at a meeting adjourned in accordance with this paragraph or paragraph 18.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|20 | At least 10 days notice of a meeting adjourned through want of a quorum shall be given in the same manner as for an original meeting
and that notice shall state the quorum required at the adjourned meeting. However, no notice need otherwise be given of an adjourned meeting.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Voting



|21 | Each question submitted to a meeting shall be decided by a show of hands unless a poll is (before, or on the declaration of the result of,
the show of hands) demanded by the chairman, the relevant Issuer, the Guarantor (if applicable) the Trustee or one or more persons holding one or more Instruments or voting certificates, in each case, representing two per cent. of the Instruments.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|22 | Unless a poll is demanded a declaration by the chairman that a resolution has or has not been passed shall be conclusive evidence of the fact
without proof of the number or proportion of the votes cast in favour of or against it.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|23 | If a poll is demanded, it shall be taken in such manner and (subject as provided below) either at once or after such adjournment as the
chairman directs. The result of the poll shall be deemed to be the resolution of the meeting at which it was demanded as at the date it was taken. A demand for a poll shall not prevent the meeting continuing for the transaction of business other
than the question on which it has been demanded.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|24 | A poll demanded on the election of a chairman or on a question of adjournment shall be taken at once.
|-- | -----------------------------------------------------------------------------------------------------



|25 | On a show of hands every person who is present in person and who produces an Instrument or a voting certificate or is a proxy or
representative has one vote. On a poll every such person has one vote in respect of each nominal amount integral currency unit of the specified currency of such Series of Instruments so produced or represented by the voting certificate so produced
or for which he is a proxy or representative. Without prejudice to the obligations of proxies, a person entitled to more than one vote need not use them all or cast them all in the same way.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|26 | In case of equality of votes the chairman shall both on a show of hands and on a poll have a casting vote in addition to any other votes
which he may have.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------

Effect and Publication of an Extraordinary Resolution



|27 | An Extraordinary Resolution shall be binding on all the Instrumentholders, whether or not present at the meeting, and on all the
Couponholders and each of them shall be bound to give effect to it accordingly. The passing of such a resolution shall be conclusive evidence that the circumstances justify its being passed. The relevant Issuer shall give notice of the passing of an
Extraordinary Resolution to Instrumentholders within 14 days but failure to do so shall not invalidate the resolution.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|28 | A resolution in writing signed by or on behalf of the holders of not less than 95 per cent. in nominal amount of the Instruments who for
the time being are entitled to receive notice of a meeting in accordance with the provisions of this Schedule shall for all purposes be as valid and effectual as an Extraordinary Resolution passed at a meeting of such Instrumentholders duly convened
and held in accordance with the provisions of this Schedule. Such resolution in writing may be contained in one document or several documents in similar form each signed by or on behalf of one or more of the Instrumentholders.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Minutes



|29 | Minutes shall be made of all resolutions and proceedings at every meeting and, if purporting to be signed by the chairman of that meeting or
of the next succeeding meeting, shall be conclusive evidence of the matters in them. Until the contrary is proved every meeting for which minutes have been so made and signed shall be deemed to have been duly convened and held and all resolutions
passed or proceedings transacted at it to have been duly passed and transacted.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Trustees Power to
Prescribe Regulations



|30 | Subject to all other provisions in this Trust Deed the Trustee may without the consent of the Instrumentholders prescribe such further
regulations regarding the holding of meetings and attendance and voting at them as it in its sole discretion determines including (without limitation) such requirements as the Trustee thinks reasonable to satisfy itself that the persons who purport
to make any requisition in accordance with this Trust Deed are entitled to do so and as to the form of voting certificates or block voting instructions so as to satisfy itself that persons who purport to attend or vote at a meeting are entitled to
do so.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|31 | The holder of a Global Instrument shall (unless such Global Instrument represents only one Instrument) be treated as two persons for the
purposes of any quorum requirements of a meeting of Instrumentholders.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|32 | The above provisions of this Schedule shall have effect subject to the following provisions:
|-- | --------------------------------------------------------------------------------------------



|32.1 | Meetings of Instrumentholders of separate Series will normally be held separately. However, the Trustee may from time to time determine that
meetings of Instrumentholders of separate Series shall be held together.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|32.2 | A resolution that in the opinion of the Trustee affects one Series alone shall be deemed to have been duly passed if passed at a separate
meeting of the Instrumentholders of the Series concerned.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|32.3 | A resolution that in the opinion of the Trustee affects the Instrumentholders of more than one Series but does not give rise to a conflict of
interest between the Instrumentholders of the different Series concerned shall be deemed to have been duly passed if passed at a single meeting of the Instrumentholders of the relevant Series provided that for the purposes of determining the votes
an Instrumentholder is entitled to cast pursuant to paragraph 25, each Instrumentholder shall have one vote in respect of each euro 1.00 nominal amount of Instruments held, converted, if such Instruments are not denominated in euro, in accordance
with Clause 8.13 (Currency Conversion).

|32.4 | A resolution that in the opinion of the Trustee affects the Instrumentholders of more than one Series and gives or may give rise to a
conflict of interest between the Instrumentholders of the different Series concerned shall be deemed to have been duly passed only if it shall be duly passed at separate meetings of the Instrumentholders of the relevant Series.
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|32.5 | To all such meetings as previously set out all the preceding provisions of this Schedule shall mutatis mutandis apply as though references
therein to Instruments and to Instrumentholders were references to the Instruments and Instrumentholders of the Series concerned.
