Instrumentholders, Receipts, Coupons, Couponholders and Talons, together with all other terms that relate to Instruments or their Conditions, shall be
construed as referring to those of the particular Series in question and not of all Series unless expressly so provided, so that each Series shall be constituted by a separate trust pursuant to Clause 2.3 (Covenant to Pay) and that, unless expressly
provided, events affecting one Series shall not affect any other.



|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 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, Receipts or the Coupons by the relevant Issuer 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 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
|--- | -----------------------

At any time after an Event of Default or a Potential Event of Default has occurred the Trustee may:



| | 2.5.1 | by notice in writing to the relevant Issuer and the Paying
Agents, require the Paying Agents, until notified by the Trustee to the contrary, so far as permitted by applicable law:
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (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, Receipts, Coupons and Talons and all moneys, documents and records held by them in respect of Instruments, Receipts, Coupons and Talons to the order of the Trustee; or

---

| | (ii) | to deliver all Instruments, Receipts, Coupons and Talons and all moneys, documents and records held by them in respect of the Instruments, Receipts, 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, require such
Issuer to make all subsequent payments in respect of the Instruments, Receipts, 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, 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 a temporary Global Instrument shall
be exchangeable for Definitive Instruments or interests in a permanent Global Instrument as set out in each temporary Global Instrument. Interests in a permanent Global Instrument shall be exchangeable for Definitive Instruments as set out in such
permanent Global Instrument.



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

The Definitive Instruments, Receipts, 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, Receipts, 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, Receipts, 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, Receipts, 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 any photostatic copying or other duplication of any Global Instruments (in unauthenticated form, but executed manually on behalf
of the



|          |  |   |  | 
|--------- |  | - |  | 
|A13584616 |  | 8 |  | 



---

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, Receipt, 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 Issuer 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 issued by it and the related Receipts,
Coupons and Talons and the execution or delivery of this Trust Deed. Each Issuer shall also indemnify the Trustee, the relevant 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 relevant Instrumentholders or the Couponholders to enforce the relevant Issuers obligations under this
Trust Deed or the relevant Instruments, Receipts, Coupons or Talons.



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

If an Issuer 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 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 has become so subject. In such event this Trust Deed and the
relevant Instruments, Receipts, Coupons and Talons shall be read accordingly.



|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, 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
relevant Instruments, Receipts or Coupons pari passu and rateably; and
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------



| | 5.1.3 | thirdly, in payment of any balance to such Issuer for itself.
| | ----- | -------------------------------------------------------------



|          |  |   |  | 
|--------- |  | - |  | 
|A13584616 |  | 9 |  | 



---

If the Trustee holds any moneys which represent principal, premium or interest in
respect of Instruments, Receipts 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 standard 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 issued by it is outstanding, each of the Issuers shall:



|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 and/or the relevant subsidiary undertaking has no reasonable
objection, access to its books of account at all reasonable times during normal business hours.



|6.2 | Notice of Events of Default
|--- | ---------------------------

Notify the Trustee in writing immediately on becoming aware of the occurrence of any Event of Default or Potential Event of Default.

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;

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

|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.

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

on another stock exchange approved in writing by the Trustee.



|6.10 | Change in Agents

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 Trustee, the relevant Instruments, the Certificates, the Receipts, the Coupons, the Talons, this Trust Deed or the Agency Agreement; and
| | ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

So long as any Instrument is outstanding the relevant Issuer 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, Receipts 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
|--- | ------------------

If an Event of Default shall have occurred or 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 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 a financial institution (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 financial institutions fee shall be shared equally between the Trustee and the relevant Issuer. The determination of the relevant financial institution shall be conclusive and binding on
the relevant Issuer, the Trustee, the relevant Instrumentholders and the relevant Couponholders.

Each of the Issuers (in respect of itself and, where applicable, Instruments issued by it) 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 in relation to that Issuer 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 (in respect of Instruments issued by it) to enforce any provision of this Trust
Deed, the relevant Instruments, the Receipts, 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:

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

demand at the rate of one per cent. per annum over the base rate of The Royal Bank of Scotland plc 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 relevant Issuer 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 such Issuer 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
|--- | ---------

Each of the Issuers (in respect of itself and, where applicable, any Instruments issued by it) shall indemnify the Trustee in respect of all liabilities and expenses properly incurred by it or by anyone appointed
by it or to whom any of its functions may be delegated by it in the carrying out of its functions and against any loss, liability, cost, claim, action, demand or expense (including, but not limited to, all costs, charges and expenses properly paid
or incurred in disputing or defending any of the foregoing) which any of them may incur in relation to the relevant Issuer or that may be made against any of them arising out of or in relation to or in connection with, its appointment or the
exercise of its functions in relation to that Issuer.

---

otherwise and shall not be responsible to anyone for any loss occasioned by so acting. Any such opinion, advice or information may be sent or obtained by letter or fax and the Trustee shall not
be liable to anyone for acting in good faith on any opinion, advice or information purporting to be conveyed by such means even if it contains some error or is not authentic.

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

The Trustee need not notify anyone of the execution of this Trust Deed or do anything to find out if an National Grid Restructuring Event or NGET Restructuring Event, an Event of Default or Potential Event of
Default has occurred. Until it has actual knowledge or express notice to the contrary, the Trustee may assume that no such event has occurred and that each Issuer is performing all of its obligations under this Trust Deed and the relevant
Instruments, Receipts, Coupons and Talons provided that the Trustee shall not be treated for any purposes as having any notice or knowledge which has been obtained by it or any officer or employee of it in some capacity other than as Trustee under
this Trust Deed or in a private or confidential capacity such that it would not be proper to disclose to third parties.



|8.3 | Resolutions of Instrumentholders
|--- | --------------------------------

The Trustee shall not be responsible for having acted in good faith on a resolution purporting to have been passed at a meeting of Instrumentholders in respect of which minutes have been made and signed even if it

|8.4 | Certificate Signed by Directors, etc.
|--- | -------------------------------------

If the Trustee, in the exercise of its functions, requires to be satisfied or to have information as to any fact or the expediency of any act, it may call for and accept as sufficient evidence of that fact or the
expediency of that act a certificate signed by any two Directors of the relevant Issuer as to that fact or to the effect that, in their opinion, that act is expedient and the Trustee need not call for further evidence and shall not be responsible
for any loss occasioned by acting on such a certificate.



|8.5 | Deposit of Documents
|--- | --------------------

The Trustee may deposit this Trust Deed and any other documents with any bank or entity whose business includes the safe custody of documents or with any lawyer or firm of lawyers believed by it to be of good
repute and may pay all sums due in respect of them.



|8.6 | Discretion
|--- | ----------

The Trustee shall have absolute and uncontrolled discretion as to the exercise of its functions and shall not be responsible for any loss, liability, cost, claim, action, demand, expense or inconvenience which may
result from their exercise or non-exercise.

employed by it or be bound to supervise the proceedings or acts of any such agent.



|8.8 | Delegation

(the Substituted Territory) other than the territory to the taxing jurisdiction of which (or to any such authority of or in which) such Issuer is subject generally (the Issuers Territory), the
Substituted Obligor shall (unless the Trustee otherwise agrees) give to the Trustee an undertaking satisfactory to the Trustee in terms corresponding to Condition 7 with the substitution for the references in that Condition to such Issuers
Territory of references to the Substituted Territory whereupon the Trust Deed, and the relevant Instruments, Receipts, Coupons and Talons shall be read accordingly;

deemed to be amended as necessary to give effect to the substitution.



|13 | Appointment, Retirement and Removal of the Trustee
|-- | --------------------------------------------------



|13.1 | Appointment
|---- | -----------

Each of the Issuers has the power of appointing new trustees but no one may be so appointed unless previously approved by an Extraordinary Resolution. The Trustee shall at all times be a trust corporation and such
trust corporation may be the sole Trustee. Any appointment of a new Trustee shall be notified by each of the Issuers to its Instrumentholders in accordance with Condition 14 as soon as practicable.



|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 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, appoint anyone to act either as a separate Trustee in respect of any Issue or as an additional Trustee jointly with the
Trustee:



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 20 |  | 



---

| | 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 and that person remove that person. At the Trustees request, each Issuer shall forthwith do all things as may be required to
perfect such appointment or removal and each of the Issuers 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
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 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 | Instruments held in Clearing Systems and Couponholders
|-- | ------------------------------------------------------



|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 its
functions by reference to the interests of the Instrumentholders, the Trustee shall assume that the holder of each Instrument is the holder of all Receipts, Coupons and Talons relating to it.

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 either of the Issuers 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, shall only discharge such Issuer 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, the Receipts or the Coupons, the relevant Issuer shall
indemnify the recipient 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, the Receipts and/or the Coupons or any other judgment or order.

otherwise, and no Instrumentholder or Couponholder shall be entitled to proceed directly against the relevant Issuer 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 or to appoint an independent financial advisor pursuant to the
Conditions of the Instruments unless it shall be indemnified and/or secured and/or prefunded by the relevant 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 or appointment, including the costs of its managements time and/or other internal resources, calculated using its normal hourly rates
in force from time to time.

Trust Deed:

Instrument such Issuer 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 has made the same default as regards all other Instruments

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



| | 16.3.2 | proof in such proceedings that as regards any specified Coupon
such Issuer has made default in paying any sum due to the relevant Couponholder shall (unless the contrary be proved) be sufficient evidence that such Issuer has made the same default as regards all other Coupons which are then payable.

|16.4 | Powers additional to general powers
|---- | -----------------------------------

The powers conferred on the Trustee by this Clause 16 shall be in addition to any powers which may from time to time be vested in the Trustee by general law or as the holder of any Instruments or Coupons.

action or proceedings arising out of or in connection with this Trust Deed, the Instruments, the Receipts, the Coupons or the Talons (Proceedings) may be brought in such courts. Each of the Issuers irrevocably submits to the
jurisdiction of such courts and waives any objection to Proceedings in such courts on the ground of venue or on the ground that the Proceedings have been brought in an inconvenient forum. This Clause is for the benefit of each of the Trustee and the
relevant Instrumentholders and Couponholders and shall not limit the right of any of them to take Proceedings in any other court of competent jurisdiction nor shall the taking of Proceedings in any one or more jurisdictions preclude the taking of
Proceedings in any other jurisdiction (whether concurrently or not).

|1 | Interpretation and Definitions
|- | ------------------------------

References in this temporary Global Instrument to the Conditions are to the Terms and Conditions applicable to the Instruments (which are in the form set out in Part B of Schedule 2 (Terms and

for these purposes, a statement issued by a relevant Clearing System (which statement shall be made available to the bearer upon request) stating the nominal amount of Instruments represented by the temporary Global Instrument at any time shall be

|3 | Promise to Pay
|- | --------------

Subject as provided in this temporary Global Instrument, the Issuer, for value received by this temporary Global Instrument, promises to pay to the
bearer of this temporary Global Instrument, upon presentation and (when no further payment is due in respect of this temporary Global Instrument) surrender of this temporary Global Instrument, on the Maturity Date (or on such earlier date or, if the

at the rates, on the dates for payment, and in accordance with the methods of calculation provided for in the Conditions, save that the calculation is made in respect of the total aggregate amount of the Instruments, together with such other sums
and additional amounts (if any) as may be payable under the Conditions, in accordance with the Conditions.



|4 | Exchange
|- | --------

Subject as
provided in the Conditions applicable to Partly Paid Instruments, on or after the first day following the expiry of 40 days after the Issue Date (the Exchange Date), this temporary Global Instrument may be exchanged (free of

of the relevant Clearing Systems in a permanent Global Instrument or, if so specified in Part A of the Schedule to this temporary Global Instrument, for Definitive Instruments in an aggregate nominal amount equal to the nominal amount of this
temporary Global Instrument submitted for exchange provided that, in the case of any part of a D Rules Instrument submitted for exchange for interests recorded in the records of the relevant Clearing Systems in a permanent Global Instrument or
Definitive Instruments, there shall have been Certification with respect to such nominal amount submitted for such exchange dated no earlier than the Exchange Date.

Certification means the presentation to the Issuing and Paying Agent of a certificate or certificates with respect to one or more interests in this temporary Global Instrument, signed by

Upon the whole or a part of this temporary Global Instrument being exchanged for a permanent Global Instrument, such permanent Global Instrument
shall be exchangeable in accordance with its terms for Definitive Instruments.

The Definitive Instruments, for which this temporary
Global Instrument or a permanent Global Instrument may be exchangeable, shall be duly executed and authenticated, shall, in the case of

of the nominal amount hereof so exchanged shall be entered pro rata in the records of the relevant Clearing Systems and upon any such entry being made, the nominal amount of the Instruments recorded in the records of the relevant Clearing
Systems and represented by this temporary Global Instrument shall be reduced for all purposes by an amount equal to such portion so exchanged.

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

Except as otherwise specified in this temporary Global Instrument, this temporary Global Instrument is subject to the Conditions and the Trust Deed
and, until the whole of this temporary Global Instrument is exchanged for equivalent interests in a permanent Global Instrument or for Definitive Instruments, as the case may be, the holder of this temporary Global Instrument shall in all respects
be entitled to the same benefits as if it were the holder of the permanent Global Instrument (or the relevant part of it) or the Definitive Instruments, as the case may be, for which it may be exchanged as if such permanent Global Instrument or
Definitive Instruments had been issued on the Issue Date.



|6 | Payments
|- | --------

No person
shall be entitled to receive any payment in respect of the Instruments represented by this temporary Global Instrument which falls due on or after the Exchange Date unless, upon due presentation of this temporary Global Instrument for exchange,

withheld or refused by or on behalf of the Issuer.

Payments due in respect of a D Rules Instrument before the Exchange Date shall only
be made in relation to such nominal amount of this temporary Global Instrument with respect to which there shall have been Certification dated no earlier than such due date for payment.

payment falls to be made on it) surrender of it at the specified office of the Issuing and Paying Agent or of any other Paying Agent provided for in the Conditions and each payment so made will discharge the Issuers obligations in respect
thereof. Any failure to make the entries in the records of the relevant Clearing Systems referred to herein shall not affect such discharge. If any payment in full or in part of principal or in the case of Instalment Instruments, payment of an
Instalment Amount is made in respect of any Instrument represented by this temporary Global Instrument, the Issuer shall procure that details of such payment shall be entered pro rata in the records of the relevant Clearing Systems and, upon any
such entry being made, the nominal amount of the Instruments recorded in the records of the relevant Clearing Systems and represented by this temporary Global Instrument shall be reduced by the aggregate nominal amount of the Instruments so redeemed
or by the aggregate amount of the Instalment Amount so paid. If any other payments are made in respect of the Instruments represented by this temporary Global Instrument, the Issuer shall procure that a record of each

Schedule 2

Part B

Terms and Conditions of the Instruments

The following is the text of the terms and conditions which, save for the text in italics and subject to completion and amendment and as
supplemented or varied in accordance with the provisions of Part A of the relevant Final Terms, will be endorsed on the Instruments in definitive form (if any) issued in exchange for the Global Instrument(s) representing each Series. Either
(a) the full text of these terms and conditions together with the relevant provisions of Part A of the Final Terms or (b) these terms and conditions as so completed, amended, supplemented or varied (and subject to simplification by the
deletion 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 (as defined below) 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.

National Grid plc (National Grid) and National Grid Electricity Transmission plc (NGET) (each an
Issuer and together, the Issuers) have established a Euro Medium Term Note Programme (the Programme) for the issuance of up to Euro 15,000,000,000 in aggregate principal amount of debt
instruments (the Instruments). The Instruments are constituted by a Trust Deed (as amended or supplemented from time to time, the Trust Deed) dated 2 August 2011 between the Issuers and The Law Debenture
Trust Corporation p.l.c. (the Trustee, which expression shall include all persons for the time being the trustee or trustees under the Trust Deed) as trustee for the Instrumentholders (as defined below). These terms and conditions
include summaries of, and are subject to, the detailed provisions of the Trust Deed, which includes the form of the Definitive Instruments, Receipts, Coupons and Talons referred to below. An Agency Agreement (as amended or supplemented from time to
time, the Agency Agreement) dated 2 August 2011 has been entered into in relation to the Instruments between the Issuers, 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 2 August 2011 at Fifth Floor, 100 Wood Street, London EC2V 7EX) and at the specified offices of the Paying Agents.

The Instrumentholders, the holders of the interest coupons (the Coupons) appertaining to interest bearing Instruments and, where
applicable in the case of such Instruments, talons for further Coupons (the Talons) (the Couponholders) and the holders of the receipts for the payment of instalments of principal (the
Receipts) relating to Instruments of which the principal is payable in instalments are entitled to the benefit of, are bound by, and are deemed to have notice of, all the provisions of the Trust Deed and are deemed to have notice
of those provisions of the Agency Agreement applicable to them.



|1 | Form, Denomination and Title
|- | ----------------------------

The Instruments are issued in bearer form in the Specified Denomination(s) specified in the relevant Final Terms and are serially numbered. Instruments of one Specified



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 58 |  | 



---

Denomination are not exchangeable for Instruments of another Specified Denomination[ provided that in the case of any Instruments which are to be admitted to trading on a regulated market within
the European Economic Area or offered to the public in a Member State of the European Economic Area in circumstances which require the publication of a prospectus under the Prospectus Directive, the minimum Specified Denomination shall be 100,000 (or its equivalent in any other currency as at the date of issue of the relevant Instruments)*].

This Instrument is a Fixed Rate Instrument, a Floating Rate Instrument, a Zero Coupon Instrument, a Perpetual Instrument, an Index
Linked Interest Instrument, an Index Linked Redemption Instrument, an Instalment Instrument, a Dual Currency Instrument or a Partly Paid Instrument, a combination of any of the preceding or any other kind of Instrument, depending upon the Interest
and Redemption/Payment Basis specified in the relevant Final Terms.

Instruments are issued with Coupons (and, where
appropriate, a Talon) attached, save in the case of Zero Coupon Instruments in which case references to interest (other than in relation to interest due after the Maturity Date), Coupons and Talons in these Conditions are not applicable.

Instalment Instruments are issued with one or more Receipts attached. Title to the Instruments and the Receipts, Coupons and Talons
shall pass by delivery and except as ordered by a court of competent jurisdiction or as required by law, the Issuer and the Paying Agents shall be entitled to treat the bearer of any Instrument, Receipt, Coupon or Talon as the absolute owner of that
Instrument, Receipt, Coupon or Talon, as the case may be, and shall not be required to obtain any proof of ownership as to the identity of the bearer.

In these Conditions, Instrumentholder means the bearer of any Instrument of one Series only of an Issuer and the Receipts relating to it, holder (in relation to an Instrument,
Receipt, Coupon or Talon) means the bearer of any Instrument, Receipt, Coupon or Talon and capitalised terms have the meanings given to them herein, the absence of any such meaning indicating that such term is not applicable to the Instruments.



|2 | Status and Negative Pledge
|- | --------------------------



|2.1 | Status
|--- | ------

The Instruments and the Receipts and Coupons relating to them constitute direct, unconditional and unsecured obligations of the
Issuer and rank pari passu without any preference or priority among themselves. The payment obligations of the Issuer under the Instruments, Receipts and Coupons shall, subject to such exceptions as are from time to time applicable under the
laws of England and, in relation to Instruments issued by National Grid, as provided in Condition 2.2, rank equally with all other present and future unsecured obligations (other than subordinated obligations, if any) of the Issuer.



|2.2 | Negative Pledge
|--- | ---------------

So long as any Instrument, Receipt or Coupon of National Grid remains outstanding (as defined in the Trust Deed) National Grid will not create or permit to subsist any mortgage,

charge, pledge, lien or other form of encumbrance or security interest
(Security) upon the whole or any part of its undertaking, assets or revenues present or future to secure any Relevant Indebtedness, or any guarantee of or indemnity in respect of any Relevant Indebtedness unless, at the same time
or prior thereto, National Grids obligations under the Instruments, the Receipts, the Coupons and the Trust Deed (a) are secured equally and rateably therewith or benefit from a guarantee or indemnity in substantially identical terms
thereto, as the case may be, in each case to the satisfaction of the Trustee, or (b) have the benefit of such other security, guarantee, indemnity or other arrangement as the Trustee in its absolute discretion shall deem to be not materially
less beneficial to the Instrumentholders or as shall be approved by an Extraordinary Resolution (as defined in the Trust Deed) of the Instrumentholders.

For the purposes of these Conditions, Relevant Indebtedness means any present or future indebtedness in the form of, or represented by, bonds, notes, debentures, loan stock or other securities
which are for the time being, or are intended, with the agreement of the Issuer, to be quoted, listed or ordinarily dealt in on any stock exchange.



|3 | Interest

|3.1 | Interest on Fixed Rate Instruments
|--- | ----------------------------------

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

If
a Fixed Coupon Amount or a Broken Amount is specified in the relevant Final Terms, the amount of interest payable on each Interest Payment Date will amount to the Fixed Coupon Amount, or, if applicable, the Broken Amount so specified and in the case
of a Broken Amount will be payable on the particular Interest Payment Date(s) specified in the relevant Final Terms.



|3.2 | Interest on Floating Rate Instruments and Index Linked Interest Instruments
|--- | ---------------------------------------------------------------------------



| | 3.2.1 | Interest Payment Dates
| | ----- | ----------------------

Each Floating Rate Instrument and Index Linked Interest Instrument bears interest on its outstanding nominal amount from the
Interest Commencement Date at the rate per annum (expressed as a percentage) equal to the Rate of Interest, such interest being payable in arrear on each Interest Payment Date. The amount of Interest payable shall be determined in accordance with
Condition 3.2.4(f). Such Interest Payment Date(s) is/are either specified in the relevant Final Terms as Specified Interest Payment Dates or, if no Specified Interest Payment Date(s) is/are specified in the relevant Final Terms, Interest Payment
Date shall mean each date which falls the number of months or other period shown on this Instrument as the Interest Period after the preceding Interest Payment Date or, in the case of the first Interest Payment Date, after the Interest Commencement
Date.



| | 3.2.2 | Business Day Convention
| | ----- | -----------------------

If any date which is specified to be subject to adjustment in accordance with a Business Day Convention would otherwise fall on a
day which is not a Business Day, then, if the Business Day Convention specified is (a) the Floating Rate

Convention, such date shall be postponed to the next day which is a Business Day
unless it would then fall into the next calendar month, in which event (x) such date shall be brought forward to the immediately preceding Business Day and (y) each subsequent such date shall be the last Business Day of the month in which
such date would have fallen had it not been subject to adjustment, (b) the Following Business Day Convention, such date shall be postponed to the next day which is a Business Day, (c) the Modified Following Business Day Convention, such
date shall be postponed to the next day which is a Business Day unless it would then fall into the next calendar month, in that event such date shall be brought forward to the immediately preceding Business Day or (d) the Preceding Business Day
Convention, such date shall be brought forward to the immediately preceding Business Day.



| | 3.2.3 | Rate of Interest for Floating Rate Instruments
| | ----- | ----------------------------------------------

The Rate of Interest in respect of Floating Rate Instruments for each Interest Accrual
Period shall be determined in the manner specified in the relevant Final Terms and the provisions below relating to either ISDA Determination or Screen Rate Determination shall apply, depending upon which is specified on this Instrument.



| | (a) | ISDA Determination for Floating Rate Instruments: Where ISDA Determination is specified in the relevant Final Terms as the manner in which the Rate of
Interest is to be determined, the Rate of Interest for each Interest Accrual Period shall be determined by the Calculation Agent as a rate equal to the relevant ISDA Rate. For the purposes of this sub-paragraph (a), ISDA Rate for
an Interest Accrual Period means a rate equal to the Floating Rate which would be determined by the Calculation Agent under a Swap Transaction under the terms of an agreement incorporating the ISDA Definitions and under which:
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | the Floating Rate Option is as specified in the relevant Final Terms;
| | --- | ---------------------------------------------------------------------



| | (ii) | the Designated Maturity is a period specified in the relevant Final Terms; and
| | ---- | ------------------------------------------------------------------------------



| | (iii) | the relevant Reset Date is the first day of that Interest Accrual Period unless otherwise specified in the relevant Final Terms.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------

For the purposes of this sub-paragraph (a), Floating Rate, Calculation Agent,
Floating Rate Option, Designated Maturity, Reset Date and Swap Transaction have the meanings given to those terms in the ISDA Definitions.



| | (b) | Screen Rate Determination for Floating Rate Instruments:
| | --- | --------------------------------------------------------



| | (i) | 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 will, subject as provided below, be either:
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (x) | the offered quotation; or
| | --- | -------------------------



| | (y) | the arithmetic mean of the offered quotations,
| | --- | ----------------------------------------------



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 61 |  | 



---

(expressed as a percentage rate per annum) for the Reference Rate which appears or
appear, as the case may be, on the Relevant Screen Page as at either 11.00 a.m. (London time in the case of LIBOR or Brussels time in the case of EURIBOR) on the Interest Determination Date in question as determined by the Calculation Agent. If
five or more of such offered quotations are available on the Relevant Screen Page, the highest (or, if there is more than one such highest quotation, one only of such quotations) and the lowest (or, if there is more than one such lowest quotation,
one only of such quotations) shall be disregarded by the Calculation Agent for the purpose of determining the arithmetic mean of such offered quotations.

If the Reference Rate from time to time in respect of Floating Rate Instruments is specified hereon as being other than LIBOR or EURIBOR, the Rate of Interest in respect of such Instruments will be determined as
provided hereon.



| | (ii) | if the Relevant Screen Page is not available or if, sub-paragraph (i)(x) applies and no such offered quotation appears on the Relevant Screen Page or if
sub-paragraph (i)(y) above applies and fewer than three such offered quotations appear on the Relevant Screen Page in each case as at the time specified above, subject as provided below, the Calculation Agent shall request, if the Reference Rate is
LIBOR, the principal London office of each of the Reference Banks or, if the Reference Rate is EURIBOR, the principal Euro-zone office of each of the Reference Banks, to provide the Calculation Agent with its offered quotation (expressed as a
percentage rate per annum) for the Reference Rate if the Reference Rate is LIBOR, at approximately 11.00 a.m. (London time), or if the Reference Rate is EURIBOR, at approximately 11.00 a.m. (Brussels time) on the Interest Determination Date in
question. If two or more of the Reference Banks provide the Calculation Agent with such offered quotations, the Rate of Interest for such Interest Period shall be the arithmetic mean of such offered quotations as determined by the Calculation Agent;
and
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | if paragraph (ii) above applies and the Calculation Agent determines that fewer than two Reference Banks are providing offered quotations, subject as
provided below, the Rate of Interest shall be the arithmetic mean of the rates per annum (expressed as a percentage) as communicated to (and at the request of) the Calculation Agent by the Reference Banks or any two or more of them, at which such
banks were offered, if the Reference Rate is LIBOR, at approximately 11.00 a.m. (London time) or, if the Reference Rate is EURIBOR, at approximately 11.00 a.m. (Brussels time) on the relevant Interest Determination Date, deposits in the Specified
Currency for a period equal to that which would have been used for the Reference Rate by leading banks in, if the Reference Rate is LIBOR, the London inter-bank market or, if the Reference Rate is EURIBOR, the Euro-zone inter-bank market, as the
case
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|--------- |  | -- |  | 
|A13584616 |  | 62 |  | 



---

may be, or, if fewer than two of the Reference Banks provide the Calculation Agent
with such offered rates, the offered rate for deposits in the Specified Currency for a period equal to that which would have been used for the Reference Rate, or the arithmetic mean of the offered rates for deposits in the Specified Currency for a
period equal to that which would have been used for the Reference Rate, at which, if the Reference Rate is LIBOR, at approximately 11.00 a.m. (London time) or, if the Reference Rate is EURIBOR, at approximately 11.00 a.m. (Brussels time), on the
relevant Interest Determination Date, any one or more banks (which bank or banks is or are in the opinion of the Trustee and the Issuer suitable for such purpose) informs the Calculation Agent it is quoting to leading banks in, if the Reference Rate
is LIBOR, the London inter-bank market or, if the Reference Rate is EURIBOR, the Euro-zone inter-bank market, as the case may be, provided that, if the Rate of Interest cannot be determined in accordance with the foregoing provisions of this
paragraph, the Rate of Interest shall be determined as at the last preceding Interest Determination Date (though substituting, where a different Margin or Maximum or Minimum Rate of Interest is to be applied to the relevant Interest Accrual Period
from that which applied to the last preceding Interest Accrual Period, the Margin or Maximum or Minimum Rate of Interest relating to the relevant Interest Accrual Period, in place of the Margin or Maximum or Minimum Rate of Interest relating to that
last preceding Interest Accrual Period).



| | 3.2.4 | Rate of Interest for Index Linked Interest Instruments
| | ----- | ------------------------------------------------------

The Rate of Interest in respect of Index Linked Interest Instruments for each Interest
Accrual Period shall be determined in the manner specified in the relevant Final Terms and interest will accrue by reference to an Index or Formula as specified in the relevant Final Terms.



| | (a) | Zero Coupon Instruments
| | --- | -----------------------

Where an Instrument, the Interest Basis of which is specified to be Zero Coupon, is repayable prior to the Maturity Date and is not paid when due, the amount due and payable prior to the Maturity Date shall be the
Early Redemption Amount of such Instrument. As from the Maturity Date, the Rate of Interest for any overdue principal of such an Instrument shall be a rate per annum (expressed as a percentage) equal to the Amortisation Yield (as defined in
Condition 5.4.1(b)).



| | (b) | Dual Currency Instruments
| | --- | -------------------------

In the case of Dual Currency Instruments, if the rate or amount of interest falls to be determined by reference to a Rate of Exchange or a method of calculating a Rate of Exchange, the rate or amount of interest
payable shall be determined in the manner specified in the relevant Final Terms.



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 63 |  | 



---

| | (c) | Partly Paid Instruments
| | --- | -----------------------

In the case of Partly Paid Instruments (other than Partly Paid Instruments which are Zero Coupon Instruments), interest will accrue as previously stated on the paid-up nominal amount of such Instruments and
otherwise as specified in the relevant Final Terms.



| | (d) | Accrual of Interest
| | --- | -------------------

Interest shall cease to accrue on each Instrument on the due date for redemption unless, upon due presentation, payment is improperly withheld or refused, in which event interest shall continue to accrue (as well
after as before judgment) at the Rate of Interest in the manner provided in this Condition 3 to the Relevant Date (as defined in Condition 7).



| | (e) | Margin, Maximum/Minimum Rates of Interest, Instalment Amounts and Redemption Amounts 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 3.2.3(b) 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, Instalment Amount or Redemption Amount is specified in the relevant Final Terms, then any Rate of Interest,
Instalment Amount or Redemption Amount shall be subject to such maximum or minimum, as the case may be.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | For the purposes of any calculations required pursuant to these Conditions (unless otherwise specified), (x) all percentages resulting from such
calculations shall be rounded, if necessary, to the nearest one hundred thousandth of a percentage point (with halves being rounded up), (y) all figures shall be rounded to seven significant figures (with halves being rounded up) and
(z) all currency amounts that fall due and payable shall be rounded to the nearest unit of such currency (with halves being rounded up), save in the case of yen, which shall be rounded down to the nearest yen. For these purposes
unit means the lowest amount of such currency which is available as legal tender in the country of such currency.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | Calculations
| | --- | ------------

The amount of interest payable per Calculation Amount in respect of any Instrument for any Interest Accrual Period shall be equal to the product of the Rate of Interest, the Calculation Amount as specified in the
relevant Final Terms, and the Day Count Fraction for such Interest Accrual Period, unless an Interest Amount (or a formula for its calculation) is applicable to such Interest Accrual Period, in which case the amount of interest payable per
Calculation Amount in respect of such Instrument for such Interest Accrual Period shall equal such Interest Amount (or be calculated in



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 64 |  | 



---

accordance with such formula). Where any Interest Period comprises two or more Interest Accrual Periods, the amount of interest payable per Calculation Amount in respect of such Interest Period
shall be the sum of the Interest Amounts payable in respect of each of those Interest Accrual Periods. In respect of any other period for which interest is required to be calculated, the provisions above shall apply save that the Day Count Fraction
shall be for the period for which interest is required to be calculated.



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

The Calculation Agent shall as soon as practicable 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 or Instalment Amount, obtain such quote or make such determination or calculation, as the case may be, and cause the Rate of Interest and the Interest Amounts for each Interest
Accrual Period and the relevant Interest Payment Date and, if required to be calculated, the Final Redemption Amount, Early Redemption Amount, Optional Redemption Amount or any Instalment Amount to be notified to the Trustee, the Issuer, 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
3.2.3(b)(ii), 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.

the basic calculation of the Index which constitutes a fundamental change which would, in the opinion of (A) the Issuer be materially prejudicial to the interests of the Issuer, or (B) the Trustee (acting solely on the advice of the
Indexation Adviser), be materially prejudicial to the interests of the Instrumentholders, the Trustee will give written notice of such occurrence to the Issuer in the case of (B), and the Issuer and the Trustee (acting solely on the advice of the

the Instruments one or more adjustments to the Index or a substitute index (with or without adjustments) with the intention that the same should leave the Issuer and the Instrumentholders in no better and no worse position than they would have been
had the Index not ceased to be published or the relevant fundamental change not been made. Any Expert so appointed shall act as an expert and not as an arbitrator and all fees, costs and expenses of the Expert and of any Indexation Adviser and of
any of the Issuer and the Trustee in connection with such appointment shall be borne by the Issuer.

the Indexation Adviser) and the Issuer agree are appropriate to give effect to such adjustment or replacement. Such amendments shall be effective from the date of such notification and binding upon the Issuer, the Trustee and the Instrumentholders,
and the Issuer shall give notice to the Instrumentholders in accordance with Condition 14 of such amendments as promptly as practicable following such notification.

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

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

If the Index is replaced, the Issuer will describe the replacement Index in a supplement to the Prospectus;

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

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

|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.



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 76 |  | 



---



|
|



| | (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;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 77 |  | 



---

| | (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 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 satisfies the Trustee immediately before the giving of the notice referred to below that it would be unable to make such payment
without having to pay additional amounts as described in Condition 7, and such requirement to pay such additional amounts arises by reason of a change in the laws of the United Kingdom or any political sub-division of the United Kingdom or taxing
authority in the United Kingdom or any political sub-division of the United Kingdom or in the 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 taking reasonable measures (such measures not
involving any material additional payments by, or expense for, the Issuer), the Issuer may, at its option, at any time, having given not less than 30 nor more than 45 days notice to the Instrumentholders in accordance with Condition 14, redeem
all, but not some only, of the Instruments at their Early Redemption Amount together with interest accrued to the date of redemption provided that the date fixed for redemption shall not be earlier than 90 days prior to the earliest date on which
the Issuer 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 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 stating that the requirement referred to above cannot be avoided by the Issuer 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 and any of its subsidiary undertakings may at any time purchase Instruments (provided that all unmatured Receipts and Coupons and unexchanged Talons appertaining to them are attached or surrendered with
them) in the open market or otherwise at any price.



|5.4 | Early Redemption
|--- | ----------------



| | 5.4.1 | Zero Coupon Instruments
| | ----- | -----------------------



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



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

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



| | (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), 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 | If (i) Residual Holding Call Option is specified in the
relevant Final Terms, 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 days irrevocable notice to the Instrumentholders and the
Trustee of any such redemption pursuant to this Condition 5.5.1.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 hereon and no greater than the maximum nominal amount
(if any) permitted to be redeemed specified on this Instrument.

All Instruments in respect of
which any such notice is given shall be redeemed, or the Issuers option shall be exercised, on the date specified in such notice in accordance with this Condition.

In the case of a partial redemption or a partial exercise of an Issuers option, the notice to Instrumentholders shall also
contain the serial numbers of the Instruments to be redeemed, which shall have been drawn in such place as the Trustee may approve and in such manner as it deems appropriate, subject to compliance with any applicable laws, listing authority and
stock exchange requirements.

| | 5.6.1 | *[Redemption of Instruments issued by National Grid at the option of Instrumentholders
| | ----- | --------------------------------------------------------------------------------------

If at any time whilst any of the Instruments issued by National Grid remains outstanding, there occurs the National Grid
Restructuring Event, a Public Announcement shall be made and if, within the National Grid Restructuring Period, either:



| | (a) | (if at the time that the National Grid Restructuring Event occurs there are Rated Securities) a Rating Downgrade in respect of the National Grid Restructuring
Event occurs; or

(the National Grid Restructuring Event and Rating Downgrade or the
National Grid Restructuring Event and Negative Rating Event, as the case may be, occurring within the National Grid Restructuring Period, together called a Put Event),

then the holder of each Instrument issued by National Grid will have the option upon the giving of a Put Notice (as defined in
Condition 5.6.4) to require National Grid to redeem or, at the option of National Grid, purchase (or procure the purchase of) such Instrument on the Put Date (as defined in Condition 5.6.4) at its principal amount together with accrued interest to
the Put Date.

Promptly upon National Grid becoming aware that a Put Event has occurred, National Grid shall, or at any
time upon the Trustee becoming similarly so aware

the Trustee may, and if so requested in writing by the holders of at least one-quarter in principal amount of the Instruments then outstanding or if so directed by an Extraordinary Resolution of
the Instrumentholders, the Trustee shall, give notice (a Put Event Notice) to the Instrumentholders in accordance with Condition 14 specifying the nature of the Put Event and the procedure (as set out in Condition 5.6.4) for
exercising the option contained in this Condition 5.6.1.

National Grid shall, forthwith upon becoming aware of the
occurrence of the National Grid Restructuring Event (a) provide the Trustee with the relevant Directors Report and (b) provide or procure that the Reporting Accountants provide the Trustee with the Accountants Report. The
Directors Report and the Accountants Report shall, in the absence of manifest error, be conclusive and binding on all concerned, including the Trustee and the Instrumentholders. The Trustee shall be entitled to act, or not act, and rely
on without being expected to verify the accuracy of the same (and shall have no liability to Instrumentholders for doing so) any Directors Report and/or any Accountants Report (whether or not addressed to it).

the Trustee.

National Grid shall use reasonable endeavours to procure that there shall at the relevant time be
Reporting Accountants who have (a) entered into an engagement letter with National Grid and the Trustee which shall (i) not limit the liability of the Reporting Accountants to the Trustee by reference to a monetary cap and (ii) be
available for inspection by Instrumentholders at the principal office of the Trustee or (b) agreed to provide Accountants Reports on such other terms as National Grid and the Trustee shall approve. If National Grid, having used reasonable
endeavours, is unable to procure that there shall at the relevant time be Reporting Accountants who have entered into an engagement letter complying with (i) above, the Trustee may rely on an Accountants Report which contains a limit on
the liability of the Reporting Accountants by reference to a monetary cap or otherwise.

of such National Grid Restructuring Event, to obtain such a rating of at least investment grade (BBB- or Baa3 or their respective equivalents for the time being), provided that a Negative Rating Event shall not be deemed to have occurred in respect
of a particular National Grid Restructuring Event if the Rating Agency declining to assign a rating of at least investment grade (as described above) does not announce or publicly confirm that its declining to assign a rating of at least investment
grade was the result, in whole or in part, of any event or circumstance comprised in or arising as a result of, or in respect of, the applicable National Grid Restructuring Event (whether or not the National Grid Restructuring Event shall have
occurred at the time such investment grade rating is declined);

National Grid Restructuring Event
shall be deemed to have occurred at any time (whether or not approved by the Board of Directors of National Grid) that the sum of Disposal Percentages for National Grid within any period of 36 months commencing on or after the issue date of the

Agency and otherwise any Rateable Debt which is rated by a Rating Agency; provided that if there shall be no such Rateable Debt outstanding prior to the maturity of the Instruments, the holders of not less than one-quarter in principal amount
of outstanding Instruments may require National Grid to obtain and thereafter update on an annual basis a rating of the Instruments from a Rating Agency. In addition, National Grid may at any time obtain and thereafter update on an annual basis a

Inc. and its successors or Moodys Investors Service, Inc. and its successors or any rating agency substituted for either of them (or any permitted substitute of them) by National Grid from time to time with the prior written approval of the
Trustee;

Rating Downgrade shall be deemed to have occurred in respect of the National Grid
Restructuring Event if the then current rating whether provided by a Rating Agency at the invitation of National Grid or by its own volition assigned to the Rated Securities by any Rating Agency is withdrawn or reduced from an investment grade
rating (BBB- or Baa3 or their respective equivalents for the time being or better) to a non-investment grade rating (BB+ or Ba1 or their respective equivalents for the time being or worse) or, if a Rating Agency shall already have rated the Rated
Securities below investment grade (as described above), the rating is lowered one full rating category; provided that a Rating Downgrade otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect

|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

| | (c) | Cross-Acceleration: if (i) any other present or future Relevant Indebtedness of the Issuer [(or a Principal Subsidiary)]*becomes due and payable prior to its stated maturity by reason of any actual event of
default or (ii) any amount in respect of such Relevant Indebtedness is not paid when due or, as the case may be, within any applicable grace period, provided that the aggregate amount of the Relevant Indebtedness in respect of which one or more

provided that in the case of paragraph (b) the Trustee shall have certified that in its opinion

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

The Trustee may, at its discretion and without further notice, institute such proceedings against the Issuer as it may think fit to enforce any obligation, condition or provision binding on the Issuer under the
Instruments or under the Trust Deed, but shall not be bound to do so unless:



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



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

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



|11 | Meetings of Instrumentholders, Modifications and Substitution
|-- | -------------------------------------------------------------



|11.1 | Meetings of Instrumentholders
|---- | -----------------------------

The Trust Deed contains provisions for convening meetings of Instrumentholders to consider any matter affecting their interests, including the sanctioning by Extraordinary Resolution (as defined in the Trust Deed)
of a modification of any of these Conditions or any provisions of the Trust Deed. An Extraordinary Resolution duly passed at any such meeting shall be binding on Instrumentholders (whether or not they were present at the



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 95 |  | 



---

meeting at which such resolution was passed) and on all Couponholders, except that any Extraordinary Resolution proposed, inter alia, (a) to amend the dates of maturity or redemption
of the Instruments, any Instalment Date or any date for payment of interest on the Instruments, (b) to reduce or cancel the nominal amount of, or any Instalment Amount of, or any premium payable on redemption of, the Instruments, (c) to
reduce the rate or rates of interest in respect of the Instruments or to vary the method or basis of calculating the rate or rates or amount of interest or the basis for calculating any Interest Amount in respect of the Instruments, (d) if a
Minimum and/or a Maximum Rate of Interest is shown on the face of the Instrument, to reduce any such Minimum and/or Maximum Rate of Interest, (e) to vary any method of calculating the Final Redemption Amount, the Early Redemption Amount or the
Optional Redemption Amount, (f) 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, and (g) to modify the provisions
concerning the quorum required at any meeting of Instrumentholders or the majority required to pass the Extraordinary Resolution 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 (a) any modification of any of the provisions of the Trust Deed that is of a formal, minor or technical nature or is
made to correct a manifest error, and (b) any other modification (except as mentioned in the Trust Deed), and any waiver or authorisation of any breach or proposed breach, of any of the provisions of the Trust Deed that is in the opinion of the
Trustee not materially prejudicial to the interests of the Instrumentholders. 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 any other company in place of the Issuer or of any previous substituted company, as principal debtor under the Trust Deed and the Instruments. In the case of such a substitution the Trustee may agree,
without the consent of the Instrumentholders or the Couponholders, to a change of the law governing the Instruments, the Receipts, the Coupons, the Talons and/or the Trust Deed provided that such change would not in the opinion of the Trustee be
materially prejudicial to the interests of the Instrumentholders.

---

|11.4 | Entitlement of the Trustee
|---- | --------------------------

In connection with the exercise of its functions (including but not limited to those referred to in this Condition) the Trustee shall have regard to the interests of the Instrumentholders as a class and shall not
have regard to the consequences of such exercise for individual Instrumentholders or Couponholders and the Trustee shall not be entitled to require, nor shall any Instrumentholder or Couponholder be entitled to claim, from the Issuer any
indemnification or payment in respect of any tax consequence of any such exercise upon individual Instrumentholders or Couponholders.



|12 | Replacement of Instruments, Receipts, Coupons and Talons
|-- | --------------------------------------------------------

If an Instrument, Receipt, Coupon or Talon is lost, stolen, mutilated, defaced or destroyed, it may be replaced, subject to
applicable laws, listing authority and stock exchange regulations, at the specified office of such other Paying Agent as may from time to time be designated by the Issuer for the purpose and notice of whose designation is given to Instrumentholders
in accordance with Condition 14 on payment by the claimant of the fees and costs incurred in connection with that replacement and on such terms as to evidence, security and indemnity (which may provide, inter alia, that if the allegedly lost,
stolen or destroyed Instrument, Receipt, Coupon or Talon is subsequently presented for payment or, as the case may be, for exchange for further Coupons, there shall be paid to the Issuer on demand the amount payable by the Issuer in respect of such
Instruments, Receipts, Coupons or further Coupons) and otherwise as the Issuer may require. Mutilated or defaced Instruments, Receipts, Coupons or Talons must be surrendered before replacements will be issued.



|13 | Further Issues
|-- | --------------

The Issuer may from time to time without the consent of the Instrumentholders or Couponholders create and issue further instruments having the same terms and conditions as the Instruments and so that such further
issue shall be consolidated and form a single series with such Instruments.

References in these Conditions to the
Instruments include (unless the context requires otherwise) any other instruments issued pursuant to this Condition and forming a single series with the Instruments. Any such further instruments forming a single series with Instruments constituted
by the Trust Deed or any deed supplemental to it shall, and any other instruments may (with the consent of the Trustee), be constituted by the Trust Deed.

The Trust Deed contains provisions for convening a single meeting of the Instrumentholders and the holders of instruments of other series if the Trustee so decides.



|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.



|          |  |    |  | 
|--------- |  | -- |  | 
|A13584616 |  | 97 |  | 



---

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 but not limited to provisions relieving it from any obligation to (a) appoint an
independent financial adviser and (b) take proceedings to enforce repayment unless indemnified to its satisfaction. The Trustee is entitled to enter into business transactions with the Issuer or any of its 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
|-- | ------------------------------



|17.1 | The Instruments and any non-contractual obligations arising out of or connected with them are governed by, and shall be construed in accordance with,
English law.
|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



|17.2 | The courts of England have exclusive jurisdiction to settle any dispute (a Dispute), arising from or connected with the Instruments.
|---- | --------------------------------------------------------------------------------------------------------------------------------------



|17.3 | The Issuer 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.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|17.4 | 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.
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

the time fixed for the meeting, (i) he must deposit the Instrument for that purpose with a Paying Agent or to the order of a Paying Agent with a bank or other depositary nominated by the Paying Agent for the purpose and (ii) he or a duly

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

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

|10.2 | the directions to which it gives effect may not be revoked or altered during the 48 hours before the time fixed for the meeting.
|---- | --------------------------------------------------------------------------------------------------------------------------------

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.

same 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 Trustee or one or more persons holding one or more Instruments or voting certificates or representing 2 per cent of the Instruments.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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.

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

|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 26, each Instrumentholder shall have one vote in respect of each whole 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

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



|32.5 | To all such meetings as previously set out all the preceding provisions of this Schedule shall mutatis mutandis apply as though references
