|2 | Issue of Instruments and Covenant to Pay
|- | ----------------------------------------



|2.1 | Issue of Instruments
|--- | --------------------

Each of the Issuers may from time to time issue Instruments in Tranches of one or more Series on a continuous basis with no minimum issue size in accordance with the Dealer Agreement. Before issuing any
Tranche and not later than, (i) in case of Instruments other than Australian Domestic Instruments, 3.00 p.m. (London time) on the second business day in London which for this purpose shall be a day on which commercial banks are open for general
business in London preceding each proposed issue date; or (ii) in case of Australian Domestic Instruments, 3.00 p.m. (Sydney time) on the second business day in Sydney which for this purpose shall be a day on which commercial banks are open for
general business in Sydney preceding each proposed issue date, the relevant Issuer shall give written notice or procure that it is given to the Trustee of the proposed issue of such Tranche, specifying the details to be included in the relevant
Final Terms. Upon the issue by either of the Issuers of any Instruments expressed to be constituted by this Trust Deed, such Instruments shall forthwith be constituted by this Trust Deed without any further formality and irrespective of whether or
not the issue of such debt securities contravenes any covenant or other restriction in this Trust Deed or the Programme Limit. For the avoidance of doubt, the parties acknowledge that the Australian Domestic Instruments are not constituted by this
Trust Deed.



|2.2 | Separate Series
|--- | ---------------

The provisions of Clauses 2.3 (Covenant to Pay), 2.4 (Discharge), 2.5 (Payment after a Default) and 2.6 (Rate of Interest after a Default) and of Clauses 3 (Form of the Instruments) to 15 (Currency
Indemnity) and Schedule 3 (Provisions for Meetings of Instrumentholders) (all inclusive) shall apply mutatis mutandis separately and independently to the Instruments of each Series and in such Clauses and Schedule the expressions
Instrumentholders, 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





A30298499

---

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) subject to the provisions of Clause 2.5, payment of any
sum due in respect of the Instruments made to the Issuing and Paying Agent or Canadian Paying Agent, as applicable, 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 Canadian Paying Agent, as applicable, 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. For the avoidance of doubt, the parties acknowledge that this Clause does not apply to Australian Domestic Instruments.



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

Subject to Clause 2.5 (Payment after a Default), any payment to be made in respect of the Instruments or the Coupons by the relevant Issuer 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 (other than the Australian Domestic 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 (other than the Australian Domestic Instruments) on the terms of this Trust Deed) and thereafter to hold all Instruments (other than the Australian Domestic

| | Instruments), Coupons and Talons and all moneys, documents and records held by them in respect of Instruments (other than the Australian Domestic Instruments), Coupons and Talons to the order of
the Trustee; or
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | 2.5.2 | by notice in writing to the relevant Issuer, require such Issuer to make all subsequent payments in respect of the Instruments (other than
the Australian Domestic Instruments), Coupons and Talons to or to the order of the Trustee and not to the Issuing and Paying Agent or Canadian Paying Agent, as applicable, 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 (other than the Australian Domestic 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, 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 (other than the Australian Domestic Instruments and Instruments settling in CDS Clearing and Depository Services Inc. (CDS)), Coupons and Talons shall be signed manually
or in facsimile by an authorised signatory of the relevant Issuer and the Instruments (other than the Australian Domestic Instruments) shall be authenticated by or on behalf of the Issuing and Paying Agent. The relevant Issuer may use the facsimile





A30298499

9



---

signature of any person who at the date of this Trust Deed is such an authorised signatory even if at the time of issue of any Instruments, Coupons or Talons he no longer holds that office. In
the case of a Global Instrument which is a NGN, the Issuing and Paying Agent shall also instruct the Common Safekeeper to effectuate the same. Instruments settling in CDS will be signed manually by an authorised signatory of the relevant Issuer
(unless CDS agrees that it will accept a facsimile signature) and the Instruments shall be authenticated by or on behalf of the Canadian Paying Agent. The Australian Domestic Instruments will be inscribed in a register maintained by the Australian
Registrar in accordance with the Australian Agency and Registry Agreement. Instruments, Coupons and Talons so executed and authenticated (and effectuated, if applicable) shall be binding and valid obligations of the relevant Issuer. Execution in
facsimile of any Instruments and any photostatic copying or other duplication of any Global Instruments (in unauthenticated form, but executed manually on behalf of the relevant Issuer as stated above) shall be binding upon such Issuer in the same
manner as if such Instruments were signed manually by such signatories.



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

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



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



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

Each Issuer shall pay any stamp, issue, documentary or other taxes and duties, payable in the United Kingdom or Australia, in respect of the creation, issue and offering of the Instruments issued by it
and the related 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, 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, 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 or Coupons pari passu and rateably; and
| | ----- | ------------------------------------------------------------------------------------------------------------------------



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

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



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

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



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

Moneys held by the Trustee may be invested in its name or under its control in any investments or other assets anywhere, whether or not they produce income, or deposited in its name or under its control
at such bank or other financial institution in such currency as the Trustee may, in its absolute discretion, think fit. If that bank or institution is the Trustee or a subsidiary, parent or associated undertaking of the Trustee, it need only account
for an amount of interest equal to the 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





A30298499

11



---

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.

each financial year, three copies in English of every balance sheet, profit and loss account, report or other notice, statement or circular issued, or that legally or contractually should be issued, to the members or creditors (or any class of them)
of the relevant Issuer or any parent undertaking of it generally in their capacity as such; and
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.4.2 | National Grid shall, forthwith upon becoming aware of the occurrence of a National Grid Restructuring Event, provide or procure that the
Reporting Accountants provide the Trustee with the Accountants Report.

of any request by the Trustee a certificate of the relevant Issuer signed by a director that, having made all reasonable enquiries, to the best of the knowledge, information and belief of such Issuer as at a date (the Certification
Date) not more than five days before the date of the certificate no Event of Default or Potential Event of Default had occurred (and, in the case of a Potential Event of Default, was continuing) since the Certification Date of the last
such certificate or (if none) the date of this Trust Deed or, if such an event had occurred (and, in the case of a Potential Event of Default, was continuing), giving details of it and certifying that it has complied with its obligations under this
Trust Deed or, to the extent that it has failed so to comply, stating such;
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.5.2 | National Grid shall, forthwith upon becoming aware of the occurrence of a National Grid Restructuring Event, notify the Trustee in writing of
the occurrence of an National Grid Restructuring Event and provide the Trustee with the directors Report; and
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.5.3 | in relation to Instruments issued by it, National Grid shall give to the Trustee, as soon as reasonably practicable after the acquisition or
disposal of any company which thereby becomes a Principal Subsidiary or after any transfer is made to any member of the National Grid Group (as defined in Condition 9(c)) which thereby

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

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



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

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



|6.8 | Notice of Late Payment
|--- | ----------------------

Forthwith upon request by the Trustee (if the Trustee determines such notice is necessary) give notice to the Instrumentholders of any unconditional payment to the Issuing and Paying Agent (or the
Australian Issuing and Paying Agent or the Canadian Paying Agent, as applicable) or the Trustee of any sum due in respect of the Instruments or Coupons made after the due date for such payment.



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

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



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



| | 6.10.1 | Give at least 14 days prior notice to the Instrumentholders (other than holders of an Australian Domestic Instrument) in accordance

laws of New South Wales before the first issue of Australian Domestic Instruments occurring after the date of this Trust Deed and after each anniversary of this Trust Deed and on the date of any amendment to the Deed Poll or the Australian Agency
and Registry Agreement;
| | ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.11.3 | unless the relevant Issuer has notified the Dealers and the Trustee in writing that it does not intend to issue Instruments under the
Programme for the time being, from legal advisers reasonably acceptable to the Trustee as to such law as may reasonably be requested by the Trustee and in such form and with such content as the Trustee may require, on such occasions as the Trustee
so requests on the basis that the Trustee considers it prudent in view of a change (or proposed change) in (or in the interpretation or application of) any applicable law, regulation or circumstance materially affecting the relevant Issuer, the
Trustee, the relevant Instruments, 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 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.





A30298499

14



---

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

If an Event of Default or Potential Event of Default shall have occurred the relevant Issuer shall pay additional remuneration to the Trustee, which may be calculated using the Trustees normal
hourly rates in force from time to time. In any other case if the Trustee finds it expedient or necessary or is requested by an Issuer to undertake duties that they both agree to be of an exceptional nature or otherwise outside the scope of the
Trustees normal duties under this Trust Deed, such Issuer 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.



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

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 or
Australian 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 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:



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



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



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

The Trustee shall wherever practicable give prior notice to the 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.



|7.6 | Continuing Effect
|--- | -----------------

Clauses 7.3 (Expenses) and 7.5 (Indemnity) shall continue in full force and effect as regards the Trustee even if it no longer is Trustee.



|7.7 | Determination of Series
|--- | -----------------------

The Trustee shall be entitled in its absolute discretion to determine in respect of which Series of Instruments any costs, charge, liabilities and expenses incurred under this Trust Deed have been
incurred or to allocate any such costs, charges, liabilities and expenses between the Instruments of any two or more Series.



|8 | Provisions Supplemental to the Trustee Acts
|- | -------------------------------------------



|8.1 | Advice
|--- | ------

The Trustee may act on the opinion or advice of, or information obtained from, any expert (including, without limitation, any report or advice received from an independent financial adviser or from any
accountant pursuant to the Conditions), whether or not (1) such opinion, advice or information is addressed to the Trustee or any other person, and (2) such experts liability in respect of the same is limited by reference to a monetary cap or
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.



|8.2 | Trustee to Assume Performance
|--- | -----------------------------

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, 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: (i) to have been passed at a meeting of Instrumentholders in respect of which minutes have been made and
signed, or (ii) to be a written resolution or by way of electronic consent made in accordance with paragraph 31 of Schedule 3, even if it is later found that there was a defect in the constitution of the meeting or the passing of the resolution or
that the resolution was not valid or binding on the Instrumentholders or Couponholders.

(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, in the case of Australian Domestic Instruments, the Deed Poll), and the relevant Instruments, Coupons and Talons shall be read accordingly;

regard to the Substituted Obligors financial condition, profits or prospects or compare them with those of such Issuer;
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | such Issuer and the Substituted Obligor comply with such other requirements as the Trustee may direct in the interests of the relevant
Instrumentholders; and

Talons. Notice of the substitution shall be given to the Instrumentholders within 14 days of the execution of such documents and compliance with such requirements.



| | 12.2.3 | Completion of Substitution

relevant Instruments, Coupons and Talons shall be 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:



| | 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





A30298499

22



---

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

|14.1 | Instruments Held in Clearing Systems

have regard to any information provided to it by the relevant 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;
| | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 14.1.2 | Subject to Clause 3.4, so long as any Australian Domestic Instrument is held in a clearing system, in considering the interests of
Instrumentholders, the Trustee may have regard to any information provided to it by the relevant clearing system or its operator as to the identity (either individually or by category) of its accountholders or participants with entitlements to any
such Australian Domestic Instrument and may consider such interests on the basis that such accountholders or participants were the holder(s) of such Australian Domestic 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 the relevant clearing system 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 or an Australian Domestic 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





A30298499

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 the relevant clearing system 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

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 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 and/or the Coupons or any other judgment or order.

under this Trust Deed:

then payable; and

jurisdiction of such courts and waives any objections to Australian Proceedings in such courts on the ground of venue or on the ground that the Australian Proceedings have been brought in an inconvenient forum. This submission is for the benefit of
each of the Trustee and the holders of Australian Domestic Instruments and shall not limit the right of any of them to take Australian Proceedings in any other court of competent jurisdiction nor shall the taking of Australian Proceedings in any one

|2 | Aggregate Nominal Amount
|- | ------------------------

The aggregate nominal amount from time to time of this temporary Global Instrument shall be an amount equal to the aggregate nominal amount of the Instruments from time to time entered in the records of
both Euroclear and Clearstream, Luxembourg (together the relevant Clearing Systems), which shall be completed by or on behalf of the Issuing and Paying Agent upon (a) the issue of Instruments represented by this temporary

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

|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

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 Euroclear or Clearstream, Luxembourg, substantially to the effect set out in Schedule 3 (Provisions for Meetings of Instrumentholders) to the Trust Deed to the effect that it has received a certificate or certificates substantially to the

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.

|- | --------

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

Instruments, as the case may be, is improperly 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.

Any payments which are made in respect of this temporary Global Instrument shall be made to its
holder against presentation and (if no further 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 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. 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 such payment shall be entered pro rata in the records of the relevant Clearing Systems). Condition 6.5(e) and

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 by 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 and incorporated by reference into each Australian Domestic Instrument. 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 (and subject to simplification by the dis-application of non-applicable
provisions), shall be endorsed on such definitive 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 and incorporated by reference into each Australian Domestic Instrument. In the case of PSM Instruments issued under the Programme, references to the Final Terms in these Conditions shall be construed as
references to the Pricing Supplement.

References in these terms and conditions (the 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, other than the Australian Domestic Instruments (as defined below), are constituted by a Trust Deed (as amended or supplemented from time to time, the Trust Deed)
dated 21 September 2015 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 Conditions include summaries of, and are subject to, the detailed provisions of the Trust Deed, which includes the form of the Definitive Instruments, Coupons and Talons referred to below. An
Agency Agreement (as amended or supplemented from time to time, the Agency Agreement) dated 12 September 2014 has been entered into in relation to the Instruments (other than the Australian Domestic Instruments) between the
Issuers, the Trustee, The Bank of New York Mellon, London Branch 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).

Instruments (the Australian Domestic Instruments) may be issued under a deed poll (as amended or supplemented from
time to time, the Australian Deed Poll) dated 10 September 2012 made by the Issuers in favour of the Trustee and the holders of those Instruments. The provisions of these Conditions relating to Coupons and Talons (each as
defined below) do not apply to Australian Domestic Instruments. An agency and registry agreement (as amended or supplemented from time to time, the Australian Agency and Registry Agreement) dated 10 September 2012 has been
entered into in relation to the Australian Domestic Instruments between the Issuers and BTA Institutional Services Australia Ltd as issuing and paying agent and registrar (the Australian Issuing and Paying Agent and the
Australian Registrar). The Australian





A30298499

Registrar will maintain a register of holders of the Australian Domestic Instruments (the Australian Register). References in these terms and conditions to the Agent and the
Paying Agent and the Agency Agreement shall, in relation to the Australian Domestic Instruments, be a reference to the Australian Issuing and Paying Agent and the Australian Agency and Registry Agreement respectively.

Copies of the Trust Deed, the Agency Agreement and the Australian Agency and Registry Agreement are available for inspection during usual
business hours at the registered office of the Trustee (as at 21 September 2015 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) 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:



| | (a) | bearer form in the Specified Denomination(s) specified in the relevant Final Terms and are serially numbered; or
| | --- | ----------------------------------------------------------------------------------------------------------------



| | (b) | in the case of Australian Domestic Instruments, registered uncertificated (or inscribed) form and are constituted by the Australian Deed Poll,
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------

as specified in the relevant Final Terms.

Instruments of one Specified Denomination are not exchangeable for Instruments of another Specified Denomination.
Australian Domestic Instruments may not be exchanged for Instruments in bearer form and Instruments in bearer form may not be exchanged for Australian Domestic Instruments.

This Instrument is a Fixed Rate Instrument, a Floating Rate Instrument, a Zero Coupon Instrument, an Index Linked Interest
Instrument or an Index Linked Redemption Instrument or a combination of any of the preceding, 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. Talons may be required if more than twenty seven coupon payments are to be
made with regards to the relevant Instruments.

Title to the Instruments and 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, Coupon or Talon as the absolute owner of that Instrument, 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, holder (in relation to an Instrument, Coupon or Talon) means
the bearer of any Instrument, 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.

---

In the case of Australian Domestic Instruments, the following provisions
apply and prevail over the foregoing provisions of this Condition 1 to the extent of any inconsistency.

Australian Domestic Instruments will be debt obligations of the Issuer constituted by the Australian Deed Poll and will
take the form of entries in the Australian Register to be established and maintained by the Australian Registrar in Sydney, or such other place specified in the applicable Final Terms agreed by the Issuer with the Australian Registrar. The relevant
Issuer will arrange for the Australian Registrar to maintain the Australian Register so as to show at all times such details of the Instrumentholders and the Australian Domestic Instruments as are required to be shown on the Australian Register by
or for the effective operation of these Conditions or by law or which the relevant Issuer and Australian Registrar determine should be shown in the Australian Register. Although Australian Domestic Instruments will not be constituted by the Trust
Deed, Australian Domestic Instruments will have the benefit of, and be issued subject to, certain other provisions of the Trust Deed. The Agency Agreement is not applicable to Australian Domestic Instruments. In relation to Australian Domestic
Instruments, the expression Instrumentholder or holder means a person (or persons) whose name is for the time being entered in the Australian Register as the holder of an Australian Domestic Instrument. For the
avoidance of doubt, where an Australian Domestic Instrument is entered into the Austraclear System, the expressions Instrumentholder or holder in respect of that Australian Domestic Instrument means Austraclear
as operator of the Austraclear System.

Australian Domestic Instruments will not be serially numbered, unless
otherwise agreed with the Australian Registrar. Each entry in the Australian Register constitutes a separate and individual acknowledgement to the Trustee on behalf of, and to, the relevant Instrumentholder of the indebtedness of the relevant Issuer
to the Trustee on behalf of, and to, the relevant Instrumentholder. The obligations of the relevant Issuer in respect of each Australian Domestic Instrument constitute separate and independent obligations which the Instrumentholder and the Trustee
are entitled to enforce in accordance with (and subject to) these Conditions, the Trust Deed and the Australian Deed Poll. No certificate or other evidence of title will be issued by or on behalf of the relevant Issuer to evidence title to an
Australian Domestic Instrument unless the relevant Issuer determines that certificates should be made available or it is required to do so pursuant, to any applicable law or regulation.

No Australian Domestic Instrument will be registered in the name of more than four persons. Australian Domestic
Instruments registered in the name of more than one person are held by those persons as joint tenants. Australian Domestic Instruments will be registered by name only, without reference to any trusteeship and an entry in the Australian Register in
relation to an Australian Domestic Instrument constitutes conclusive evidence that the person so entered is the absolute owner of such Instrument, subject to rectification for fraud or error.

Title to an Australian Domestic Instrument and all rights and entitlements arising by virtue of the Australian Deed Poll
or the Trust Deed in respect of that Australian Domestic Instrument vest absolutely in the registered owner of the Australian Domestic Instrument, subject to rectification of the Australian Register for fraud or error, such that no person who has
previously been registered as the owner of the Australian Domestic Instrument has or is entitled to assert against the Issuer or the Australian Registrar or the registered owner of





A30298499

63



---

the Australian Domestic Instrument for the time being and from time to time any rights, benefits or entitlements in respect of the Australian Domestic Instrument.

Australian Domestic Instruments may be transferred in whole but not in part. Australian Domestic Instruments will be
transferred by duly completed and (if applicable) stamped transfer and acceptance forms in the form specified by, and obtainable from, the Australian Registrar or by any other manner approved by the Issuer and the Australian Registrar. Australian
Domestic Instruments entered in the Austraclear System (as defined below) will be transferable only in accordance with the Austraclear Regulations (as defined below).

Unless the Australian Domestic Instruments are lodged in the Austraclear System, application for the transfer of
Australian Domestic Instruments must be made by the lodgement of a transfer and acceptance form with the Australian Registrar. Each transfer and acceptance form must be accompanied by such evidence (if any) as the Australian Registrar may require to
prove the title of the transferor or the transferors right to transfer the Australian Domestic Instruments and must be signed by both the transferor and the transferee,

The transferor of an Australian Domestic Instrument is deemed to remain the holder of that Australian Domestic Instrument
until the name of the transferee is entered in the Australian Register in respect of that Australian Domestic Instrument. Transfers will not be registered later than eight days prior to the Maturity Date of the Australian Domestic Instrument.

Australian Domestic Instruments may only be transferred within, to or from Australia if:



| | (d) | the aggregate consideration payable by the transferee at the time of transfer is at least A$500,000 (disregarding moneys lent by the transferor or
its associates) or the offer or invitation giving rise to the transfer otherwise does not require disclosure to investors in accordance with Part 6D.2 or Part 7.9 of the Corporations Act 2001 of Australia (Australian Corporations
Act);
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | the transferee is not a retail client as defined in section 761G of the Australian Corporations Act;
| | --- | ------------------------------------------------------------------------------------------------------



| | (f) | the transfer is in compliance with all applicable laws, regulations and directives (including, without limitation, in the case of a transfer to or
from Australia, the laws of the jurisdiction in which the transfer takes place); and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | in the case of a transfer between persons outside Australia, if a transfer and acceptance form is signed outside Australia.
| | --- | ---------------------------------------------------------------------------------------------------------------------------

A transfer to an unincorporated association is not permitted.

Transfers will be registered without charge provided taxes, duties or other governmental charges (if any) imposed in
relation to the transfer have been paid.

A person becoming entitled to an Australian Domestic Instrument as a
consequence of the death or bankruptcy of a Holder or of a vesting order or a person administering the estate of a Holder may, upon producing such evidence as to that entitlement or status as the Australian Registrar considers sufficient, transfer
the Australian Domestic Instrument or, if so entitled, become registered as the holder of the Australian Domestic Instrument.

Where the transferor executes a transfer of less than all Australian Domestic Instruments registered in its name, and the specific Australian Domestic Instruments to be transferred are not identified, the
Australian Registrar may register the transfer in respect of such of





A30298499

64



---

the Australian Domestic Instruments registered in the name of the transferor as the Australian Registrar thinks fit, provided the aggregate principal amount of the Australian Domestic Instruments
registered as having been transferred equals the aggregate principal amount of the Australian Domestic Instruments expressed to be transferred in the transfer.

In this Condition 1:

Austraclear means
Austraclear Limited (ABN 94 002 060 773).

Austraclear Regulations means the rules and
regulations established by Austraclear (as amended or replaced from time to time) to govern the use of the Austraclear System.

Austraclear System means the system operated by Austraclear for holding securities and the electronic recording and settling of transactions in those securities between members of that
system.



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



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

The Instruments and the 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 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 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 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 3.6,

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 3.6. 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 specified
in the relevant Final Terms 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





A30298499

66



---

Rate Determination shall apply, depending upon which is specified in the relevant Final Terms.



| | (a) | ISDA Determination: 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:
| | --- | --------------------------



| | (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,
| | --- | ----------------------------------------------

(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 (1) 11.00 a.m. London time, in the case of LIBOR (LIBOR); or (2) 11:00 a.m. Brussels time, in the case of EURIBOR (EURIBOR); or (3) 10:10 a.m. Sydney time, in the case
of AUD-BBR-BBSW; or (4) 10:00 a.m. Toronto time, in the case of CAD-BA-CDOR; or (5) 11:00 a.m. Hong Kong time, in the case of HKD-HIBOR-HIBOR=; or (6) 11:00 a.m. Frankfurt time, in the case of EUR-ISDA-EURIBOR Swap Rate-11:00, 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.

| | (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 or, if the Reference Rate is AUD-BBR-BBSW, the principal office of each of
the Reference Banks or, if the Reference Rate is CAD-BA-CDOR, the principal Toronto office of each of the Reference Banks or, if the Reference Rate is EUR-ISDA-EURIBOR Swap Rate-11:00, the principal office of each of the Reference Banks or, if the
Reference Rate is HKD-HIBOR-HIBOR=, the principal Hong Kong 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: (1) LIBOR, at approximately 11.00 a.m. (London time), or (2) EURIBOR, at approximately 11.00 a.m. (Brussels time), or (3) AUD-BBR-BBSW, at approximately 10:00 a.m. (Sydney time), or (4) CAD-BA-CDOR, at 10:00 a.m., (Toronto
time) or (5) EUR-ISDA-EURIBOR Swap Rate-11:00, at approximately 11:00 a.m. (Frankfurt time), or (6) HKD-HIBOR-HIBOR=, at approximately 11:00 a.m. (Hong Kong time), on the Interest Determination Date in question. If, two (in the case of
LIBOR, EURIBOR, CAD-BA-CDOR or HKD-HIBOR-HIBOR=); or five (in the case of AUD-BBR-BBSW); or three (in the case of EUR-ISDA-EURIBOR Swap Rate-11:00), 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 the specified number of Reference Banks are providing
offered quotations, subject as provided below, the Rate of Interest shall be (1) in case the Reference Rate is either LIBOR or EURIBOR, 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 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; (2) in case the Reference Rate is AUD-BBR-BBSW, the rate shall then be determined by the Calculation Agent having regard to the comparable indices then available; (3) in
case the Reference Rate is EUR-ISDA-EURIBOR Swap Rate-11:00, the rate shall be the arithmetic mean of the mid-market annual swap rate quotations provided by the principal office of each of the Reference Banks, eliminating the highest quotation (or,
in the event of equality, on of the highest) and the lowest quotation (or, in the event of equality, one of the lowest); (4) in case the Reference Rate is CAD-BA-CDOR, the arithmetic mean of the bid rates as communicated to (and at the request
of) the Calculation Agent by Schedule I chartered banks in Toronto, for Canadian Dollar bankers acceptances for a period of the applicable Interest Period in an amount representative for a single transaction in the relevant market at the relevant
time accepted by those banks as of 10:00 a.m. Toronto time; and (5) in the case of HKD-HIBOR-HIBOR, the arithmetic mean of the quotations as communicated to (and at the request of) the Calculation Agent by major banks in Hong Kong, for loans in
Hong Kong Dollars to leading European banks for a period of the applicable maturity as at approximately 11:00 a.m. Hong Kong time, 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)

| | (iv) | If the Reference Rate from time to time in respect of Floating Rate Instruments is specified in the applicable Final Terms as being

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.

date on which such payment is due (the date for payment), the Index Figure applicable for the relevant calculation month shall be (1) such substitute index figure (if any) as the Trustee considers (acting solely on the advice
of the Indexation Adviser) to have been published by the United Kingdom Debt Management Office or the Bank of England, as the case may be, for the purposes of indexation of payments on the Reference Gilt or, failing such publication, on any one or
more issues of index-linked Treasury Stock selected by an Indexation Adviser (and approved by the Trustee (acting solely on the advice of the Indexation Adviser)) or (2) if no such determination is made by such Indexation Adviser within seven
days, the Index Figure last published (or, if later, the substitute index figure last determined pursuant to Condition 4.3(i)) before the date for payment.

|4.4 | Application of Changes
|--- | ----------------------

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



| | (i) | in relation to a payment of principal or interest in respect of such Instrument other than upon final redemption of such Instrument, the principal
or interest (as the case may be) next payable after the date of such subsequent publication shall be

| | increased or reduced, as the case may be, by an amount equal to the shortfall or excess, as the case may be, of the amount of the relevant payment made on the basis of the Index Figure applicable
by virtue of Condition 4.3(ii)(2) or Condition 4.3(iii)(2) below or above the amount of the relevant payment that would have been due if the Index Figure subsequently published had been published on or before the fourteenth business day before the
date for payment; and
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



|4.5 | Material Changes to or Cessation of the Index
|--- | ---------------------------------------------



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



| | (ii) | Cessation of the Index: If (1) the Trustee has been notified by the Calculation Agent that the Index has ceased to be published or (2) if
Her Majestys Treasury, or a person acting on its behalf, announces that it will no longer continue to publish the Index, then the Calculation Agent shall determine a successor index in lieu of any previously applicable index (the
Successor Index) by using the following methodology:
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | (b) | If a Successor Index has not been determined under paragraph (a) above, the Issuer and the Trustee (acting solely on the advice of the
Indexation Adviser) together shall seek to agree for the purpose of the Instruments one or more adjustments to the Index or a substitute index (with or without adjustments) with the intention that the same should leave the Issuer and the
Instrumentholders in no better and no worse position than they would have been had the Index not ceased to be published; or
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | if the Issuer and the Trustee (acting solely on the advice of the Indexation Adviser) fail to reach agreement as mentioned above within 20 business
days following the giving of notice as mentioned in paragraph (i), a bank or other person in London shall be appointed by the Issuer and the Trustee or, failing agreement on and the making of such appointment within 20 business days following the
expiry of the 20 day period referred to above, by the Trustee (acting solely on the advice of the Indexation Adviser) (in each case, such bank or other person so appointed being referred to as the Expert), to determine for the
purpose of the Instruments one or more adjustments to the Index or a substitute index (with or without adjustments) with the intention that the same should leave the Issuer and the Instrumentholders in no better and no worse position than they would
have been had the Index not ceased to be published. Any Expert so appointed shall act as an expert and not as an arbitrator and all fees, costs and expenses of the Expert and of any Indexation

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



| | (iii) | Adjustment or replacement: The Index shall be adjusted or replaced by a substitute index pursuant to the foregoing paragraphs, as the case may be,
and references in these Conditions to the Index and to any Index Figure shall be deemed amended in such manner as the Trustee (acting solely on the advice of the Indexation Adviser) 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 or adjustment.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.6 | Redemption for Index Reasons
|--- | ----------------------------

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



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

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

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

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



LOGO

where:

Id is the Index Level for the day d





A30298499

81



---

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

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

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

qm is the actual number of days in month m,

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

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

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

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

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



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

Each payment of interest and principal in respect of the Instruments shall be the amount provided in, or determined in accordance with, these Conditions, multiplied by the Index Ratio applicable to the
date on which such payment falls to be made and rounded in accordance with Condition 3.5.



|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:
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------





A30298499

82



---

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



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

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

Where:

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

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

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



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



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



| | (a) | if at any time (other than after an Early Termination Event (as defined below) has been designated by the Calculation Agent pursuant to paragraph
(e) below) a successor index has been designated by the calculation agent (or any other party performing the function of a calculation agent (whatever such partys title)) pursuant to the terms and conditions of the Related Instrument,
such successor index shall be designated the Successor Index for the purposes of all subsequent Interest Payment Dates, notwithstanding that any other Successor Index may previously have been determined under paragraph (b), (c) or
(d) below; or
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------





A30298499

83



---

| | (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 paragraph (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 paragraph (a), (b) or (c) above on or before the fifth Index Business Day prior to the
next Affected Payment Date the Calculation Agent will determine an appropriate alternative index for such Affected Payment Date, and such index will be deemed the Successor Index;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | if the Calculation Agent determines that there is no appropriate alternative index, the Issuer and the Instrumentholders shall, in conjunction with
the Calculation Agent, determine an appropriate alternative index. If the Issuer and the Instrumentholders, in conjunction with the Calculation Agent, do not reach agreement on an appropriate alternative index within a period of ten Business Days,
then an Early Termination Event will be deemed to have occurred and the Issuer will redeem the Instruments pursuant to Condition 4,10.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



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





A30298499

84



---

| | such adjustments to the Index consistent with adjustments made to the Related Instrument.
| | -----------------------------------------------------------------------------------------



| | (v) | Manifest Error in Publication: If, within 30 days of publication, the Calculation Agent determines that Eurostat (or any successor entity which
publishes such index) has corrected the level of the Index to remedy a manifest error in its original publication, the Calculation Agent will notify the parties of (A) that correction, (B) the amount that is payable as a result of that
correction and (C) take such other action as it may deem necessary to give effect to such correction.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

If an Early Termination Event as described under Condition 4.9(ii)(e) is deemed to have occurred, the Issuer will, upon giving not more than 60 nor less than 30 days notice to the Instrumentholders
(or such other notice period as may be specified in the relevant Final Terms) in accordance with Condition 14, redeem all, but not some only, of the Instruments at their principal amount together with interest accrued but unpaid up to and including
the date of redemption (in each case adjusted in accordance with Condition 4.8).



|5 | Redemption, Purchase and Options
|- | --------------------------------



|5.1 | Final Redemption
|--- | ----------------

Unless previously redeemed, purchased and cancelled as provided below, this Instrument will be redeemed at its Final Redemption Amount (which, unless otherwise provided, is its nominal amount) on the
Maturity Date specified in the relevant Final Terms provided, however, that if this Instrument is a Perpetual Instrument it will only be redeemable and repayable in accordance with the following provisions of this Condition 5.



|5.2 | Redemption for Taxation Reasons
|--- | -------------------------------

If, on the occasion of the next payment in respect of the Instruments the Issuer 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 (or such other notice
period as may be specified in the relevant Final Terms) in accordance with Condition 14, redeem all, but not some only, of the Instruments at their Early Redemption Amount together with interest accrued to the date of redemption provided that the
date fixed for redemption shall not be earlier than 90 days prior to the earliest date on which the Issuer 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





A30298499

85



---

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



| | (i) | 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.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Subject to the provisions of sub-paragraph (iii) below, the Amortised Face Amount of any such Instrument shall be the scheduled Final
Redemption Amount of such Instrument on the Maturity Date discounted at a rate per annum (expressed as a percentage) equal to the Amortisation Yield (which, if none is specified in the relevant Final Terms, shall be such rate as would produce an
Amortised Face Amount equal to the issue price of the Instruments if they were discounted back to their issue price on the Issue Date) compounded annually.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | 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 (ii) 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
| | ----- | -----------------





A30298499

86



---

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.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5.5.2 | If Call Option is specified in the relevant Final Terms, the Issuer may, unless an Exercise Notice has been given pursuant to Condition 5.6
or 5.7, 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(s) 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 but
excluding the date fixed for redemption. Any such redemption or exercise must relate to Instruments of a nominal amount at least equal to the minimum nominal amount (if any) permitted to be redeemed specified in the relevant Final Terms and no
greater than the maximum nominal amount (if any) permitted to be redeemed specified In the relevant Final Terms.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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.

| | 5.5.3 | If Make-whole Redemption Option is specified in the relevant Final Terms as applicable, the Issuer may, unless an Exercise Notice has been
given pursuant to Condition 5.6 or 5.7, 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 Make-whole Redemption Date(s). Any such redemption of Instruments shall be at an amount equal to the higher of the following, in each case together with
interest accrued to but excluding the date fixed for redemption:

| | (i) | the nominal amount of the Instrument; and
| | --- | -----------------------------------------



| | (ii) | the nominal amount of the Instrument multiplied by the price (as reported in writing to the Issuer and the Trustee by a financial adviser (the
Financial Adviser) appointed by the Issuer and approved by the Trustee) expressed as a percentage (rounded to the nearest fifth decimal places, 0.000005 being rounded upwards) at which the Gross Redemption Yield on the Instruments
on the Determination Date specified in the Final Terms is equal to the Gross Redemption Yield at the Quotation Time specified in the relevant Final Terms on the Determination Date of the Reference Bond specified in the relevant Final Terms (or,
where the Financial Adviser advises the Trustee that, for reasons of illiquidity or otherwise, such Reference Bond is not appropriate for such purpose, such other government stock as such Financial Adviser may recommend) plus any applicable
Redemption Margin specified in the Final Terms.

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 of a particular National Grid Restructuring Event if the Rating Agency making the reduction in rating to which this definition would otherwise apply does not announce or publicly confirm that the reduction was the

Instruments (in the case of all payments of principal and, in the case of interest, as specified in Condition 6.6.4) or Coupons (in the case of interest, save as specified in Condition 6.6.4), as the case may be, at the specified office of any
Paying Agent outside the United States by a cheque payable in the currency in which such payment is due drawn on, or, at the option of the holder, by transfer to an account denominated in that currency with, a bank in the principal financial centre

|6.2 | Payments in respect of Australian Domestic Instruments
|--- | ------------------------------------------------------

Payments of principal and interest in respect of Australian Domestic Instruments will be made in Australian dollars to the
persons registered in the Australian Register on the relevant Record Date (as defined below) as the holders of such Australian Domestic Instruments. Payments to holders in respect of each Australian Domestic Instrument will be made:



| | (i) | if the Australian Domestic Instrument is held by Austraclear and entered in the Austraclear System, by crediting on the relevant Interest Payment
Date, the
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------

| | Maturity Date or other date on which payment is due the amount then due to the account or accounts to which payments should be made in accordance with the Austraclear Regulations or as otherwise
agreed with Austraclear; and
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | if the Australian Domestic Instrument is not held by Austraclear and entered in the Austraclear System, by crediting on the Interest Payment Date,
the Maturity Date or other date on which payment is due, the amount then due to an account in Australia previously notified by the Instrumentholder(s) of the Australian Domestic Instrument to the relevant Issuer and the Australian Registrar.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Payment of an amount due in respect of an Australian Domestic Instrument to the holder or
otherwise in accordance with this Condition or to the Trustee discharges the obligation of the Issuer to all persons to pay that amount.

Payments will for all purposes be taken to be made when the relevant Issuer or the Agent gives irrevocable instructions for the making of the relevant payment by electronic transfer, being instructions
which would be reasonably expected to result, in the ordinary course of banking business, in the funds transferred reaching the account to which the payment is to be made on the same day as the day on which the instructions are given.

If, following the application of Condition 6.7 (Non-business days), a payment is due to be made under an Australian
Domestic Instrument to an account on a business day on which banks are not open for general banking business in the city in which the account is located, the Instrumentholder is not entitled to payment of such amount until the next business day on
which banks in such city are open for general banking business and is not entitled to any interest or other payment in respect of any such delay.

In this Condition, in relation to Australian Domestic Instruments, Record Date means, in the case of payments of principal or interest, close of business on the date which is the eighth
calendar day before the due date for the relevant payment of principal or interest.



|6.3 | Payments in the United States
|--- | -----------------------------

Notwithstanding the above, if any Instruments are denominated in U.S. dollars, payments in respect of them may be made at the specified office of any Paying Agent in New York City in the same manner as
specified above if (a) the Issuer shall have appointed Paying Agents with specified offices outside the United States with the reasonable expectation that such Paying Agents would be able to make payment of the amounts on the Instruments in the
manner provided above when due, (b) payment in full of such amounts at all such offices is illegal or effectively precluded by exchange controls or other similar restrictions on payment or receipt of such amounts and (c) such payment is
then permitted by United States law, without involving, in the opinion of the Issuer, any adverse tax consequence to the Issuer.



|6.4 | Payments subject to Fiscal Laws etc.
|--- | ------------------------------------

Save as provided in Condition 7, payments will be subject in all cases to any applicable fiscal or other laws, regulations
and directives in the place of payment and the relevant Issuer will not be liable for any taxes or duties of whatever nature imposed or levied by such laws, regulations, directives or agreements. No commission or expenses shall be charged to the
Instrumentholders or Couponholders in respect of such payments.

|6.5 | Appointment of Agents
|--- | ---------------------

The Issuing and Paying Agent, the Paying Agents and the Calculation Agent initially appointed by the Issuer and their respective specified offices are listed below. The Issuing and Paying Agent, the
Paying Agents and the Calculation Agent act solely as agents of the Issuer and do not assume any obligation or relationship of agency or trust for or with any holder. The Issuer reserves the right at any time with the approval of the Trustee to vary
or terminate the appointment of the Issuing and Paying Agent, any other Paying Agent or the Calculation Agent and to appoint additional or other Paying Agents, provided that the Issuer shall at all times maintain (a) an Issuing and Paying
Agent, (b) a Paying Agent having its specified office in a major European city, which shall be London so long as the Instruments are admitted to the Official List of the Financial Conduct Authority under Part VI of the Financial Services and

listing by any other relevant authority, a Paying Agent having a specified office in such place as may be required by the rules and regulations of any other relevant stock exchange or other relevant authority, (e) so long as the Instruments
clear in a clearing system other than or in addition to Euroclear and Clearstream, Luxembourg, a Paying Agent that is able to make payments to such clearing system in accordance with the rules and procedure of such clearing system and (f) to
the extent that the Issuer is able to do so and not provided for by the foregoing provisions of this Condition 6.5, a Paying Agent with a specified office in a European Union member state that will not be obliged to withhold or deduct tax pursuant
to any law implementing European Council Directive 2003/48/EC (as amended from time to time) or any other Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000. As used in these Conditions, the terms
Issuing and Paying Agent, Calculation Agent, and Paying Agent include any additional or replacement Issuing and Paying Agent, Calculation Agent or Paying Agent appointed under this Condition.

In addition, the Issuer shall forthwith appoint a Paying Agent in New York City in respect of any Instruments
denominated in U.S. dollars in the circumstances described in Condition 6.3.

Notice of any such change or any
change of any specified office shall promptly be given to the Instrumentholders in accordance with Condition 14.



|6.6 | Unmatured Coupons and unexchanged Talons
|--- | ----------------------------------------



| | 6.6.1 | Upon the due date for redemption of any Instrument, unmatured Coupons relating to such Instrument (whether or not attached) shall become void
and no payment shall be made in respect of them.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.6.2 | Upon the due date for redemption of any Instrument, any unexchanged Talon relating to such Instrument (whether or not attached) shall become
void and no Coupon shall be delivered in respect of such Talon.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.6.3 | Where any Instrument which provides that the relevant Coupons are to become void upon the due date for redemption of those Instruments is
presented for redemption without all unmatured Coupons, and where any Instrument is presented for redemption without any unexchanged Talon relating to it, redemption shall be made only against the provision of such indemnity as the Issuer may
require.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------





A30298499

---

| | 6.6.4 | If the due date for redemption of any Instrument is not a due date for payment of interest, interest accrued from the preceding due date for
payment of interest or the Interest Commencement Date, as the case may be, shall only be payable against presentation (and surrender if appropriate) of the relevant Instrument. Interest accrued on an Instrument that only bears interest after its
Maturity Date shall be payable on redemption of that Instrument against presentation of that Instrument.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6.7 | Non-business Days
|--- | -----------------

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



| | 6.7.1 | (in the case of a payment in a currency other than Euro) where payment is to be made by transfer to an account maintained with a bank in the
relevant currency, on which foreign exchange transactions may be carried on in the relevant currency in the principal financial centre of the country of such currency (which in the case of Australian dollars is Sydney); or
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.7.2 | (in the case of a payment in Euro) which is a TARGET Business Day.
| | ----- | ------------------------------------------------------------------



|6.8 | Talons
|--- | ------

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



|7 | Taxation
|- | --------

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



| | (a) | by or on behalf of, a person who is liable to such taxes or duties in respect of such Instrument or Coupon by reason of his having some connection
with the United Kingdom other than the mere holding of such Instrument or Coupon; or
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | by or on behalf of a person who would not be liable or subject to such deduction or withholding by making a declaration of non-residence or other
claim for exemption to a tax authority; or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------





A30298499

100



---

| | (c) | more than 30 days after the Relevant Date except to the extent that the holder would have been entitled to such additional amounts on presenting the
same for payment on such 30th day; or
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | where such withholding or deduction is imposed on a payment to an individual and is required to be made pursuant to any law implementing European
Council Directive 2003/48/EC (as amended from time to time) or any other Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000; or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | by or on behalf of a holder who would have been able to avoid such withholding or deduction (i) by presenting the relevant Instrument or Coupon
to another Paying Agent in a Member State of the European Union; or (ii) by satisfying any statutory or procedural requirements (including, without limitation, the provision of information).
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Notwithstanding any other provision of the Terms and Conditions or the Trust Deed, any amounts to be paid on the
Instruments by or on behalf of the Issuer, will be paid net of any deduction or withholding imposed or required pursuant to an agreement described in Section 1471(b) of the U.S. Internal Revenue Code of 1986, as amended (the
Code), or otherwise imposed pursuant to Sections 1471 through 1474 of the Code (or any regulations thereunder or official interpretations thereof) or an intergovernmental agreement between the United States and another
jurisdiction facilitating the implementation thereof (or any fiscal or regulatory legislation, rules or practices implementing such an intergovernmental agreement) (any such withholding or deduction, a FATCA Withholding). Neither
the Issuer nor any other person will be required to pay any additional amounts in respect of FATCA Withholding.

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



|8 | Prescription
|- | ------------

Instruments and Coupons (which, for this purpose, shall not include Talons) shall be prescribed and become void unless presented for payment within 10 years (in the case of principal) or five years (in
the case of interest) from the appropriate Relevant Date in respect of them.

|9 | Events of Default
|- | -----------------

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



| | (a) | Non-Payment: there is default for more than 30 days in the payment of any principal or interest due in respect of the Instruments; or
| | --- | -------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Breach of Other Obligations: there is default in the performance or observance by the Issuer of any other obligation or provision under the
Trust Deed or the Instruments (other than any obligation for the payment of any principal or interest in respect of the Instruments) which default is incapable of remedy or, if in the opinion of the Trustee capable of remedy, is not remedied within
90 days after notice of such default shall have been given to the Issuer by the Trustee; or
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (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 of the events mentioned above in this paragraph (c) have occurred equals or exceeds £50,000,000, for the period up to 31 March 2017, and thereafter, £100,000,000.

Grid North America Inc. and National Grid USA, and includes any successor entity thereto or any member of the group of companies comprising National Grid and each of its subsidiary undertakings (the National Grid Group) which the
Auditors have certified to the Trustee as being a company to which all or substantially all of the assets of a Principal Subsidiary are transferred. In the event that all or substantially all of the assets of a Principal Subsidiary are transferred
to a member of the National Grid Group as described above, the transferor of such assets shall cease to be deemed to be a Principal Subsidiary for the purposes of this Condition.]*; or

provided that in the case of paragraph (b) the Trustee shall have certified that in its
opinion such event is materially prejudicial to the interests of the Instrumentholders.



|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 and/or secured and/or prefunded to its satisfaction.
| | --- | ----------------------------------------------------------------------------

No Instrumentholder 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 and the Australian Deed Poll (in the case of Australian Domestic Instruments) each 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 or the Australian Deed Poll (as applicable)) of a modification of any of these Conditions or any provisions of the Trust Deed or the Australian Deed Poll
(as applicable). An Extraordinary Resolution duly passed at any such meeting shall be binding on Instrumentholders (whether or not they were present at the meeting at which such resolution was passed) and on all Couponholders, except that any
Extraordinary Resolution proposed, inter alia, (a) to amend the dates of maturity or redemption of the Instruments or any date for payment of interest on the Instruments, (b) to reduce or cancel the nominal 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





A30298499

103



---

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 or the Australian Deed Poll (as applicable)) 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 the Australian Deed Poll 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 and the Australian Deed Poll
|---- | -----------------------------------------------------------

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 or the Australian Deed Poll 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 or the Australian Deed
Poll), and any waiver or authorisation of any breach or proposed breach, of any of the provisions of the Trust Deed or the Australian Deed Poll 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/or the Australian Deed Poll 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 or the Australian Deed Poll (in the
case of Australian Domestic Instruments) 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 Coupons,
the Talons and/or the Trust Deed and/or the Australian Deed Poll (as applicable) 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.





A30298499

---

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

If an Instrument, Coupon or Talon is lost, stolen, mutilated, defaced or destroyed, it may be replaced, subject to
applicable laws, listing authority and stock exchange regulations, at the specified office of such other Paying Agent as may from time to time be designated by the 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, 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,
Coupons or further Coupons) and otherwise as the Issuer may require. Mutilated or defaced Instruments, Coupons or Talons must be surrendered before replacements will be issued.



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

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

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

The Trust Deed and the Australian Deed Poll each 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.

In the case of Australian Domestic Instruments, the following provisions shall apply in lieu of any provisions of this Condition 14 which are inconsistent with the following provisions. Notices regarding
Australian Domestic Instruments shall be published in a leading daily newspaper of general circulation in Australia. It is expected that such notices will normally be published in The Australian Financial Review. Any such notice will be
deemed to have been given to the holders on the date of such publication.

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.





A30298499

|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 (other than Australian Domestic 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 (other than Australian Domestic 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.
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|17.5 | The Australian Domestic Instruments, the Australian Deed Poll and (unless otherwise specified in the applicable Final Terms) the Australian
Agency and Registry Agreement will be governed by, and construed in accordance with, the laws in force in New South Wales, Australia, save that the provisions of Condition 9 (Events of Default) shall be interpreted so as to have the same meaning
they would have if governed by English law,
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|17.6 | In the case of Australian Domestic Instruments, each Issuer has irrevocably agreed for the benefit of Instrumentholders that the courts of
New South Wales, Australia are to have jurisdiction to settle any disputes which may arise out of or in connection with the Australian Domestic Instruments, the Australian Deed Poll and the Australian Agency and Registry Agreement and that
accordingly any suit, action or proceedings arising out of or in connection with the Australian Domestic Instruments, the Australian Deed Poll or the Australian Agency and Registry Agreement (together referred to as Australian
Proceedings) may be brought in such courts.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|17.7 | Each Issuer has irrevocably waived any objection which it may have now or hereafter to the laying of the venue of any Australian Proceedings
in any such court and any claim that any such Australian Proceedings have been brought in an inconvenient forum and has
|---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

further irrevocably agreed that a judgment in any such Australian Proceedings brought in the courts of New South Wales shall be conclusive and binding upon it and may be enforced in the courts of
any other jurisdiction.

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



|11.1 | it shall not release the Instruments, except as provided in paragraph 12, until the meeting has been concluded; and

Agent at least 48 hours before the time fixed for the meeting, the Paying Agent shall release the Instrument and exclude the votes attributable to it from the block voting instruction.

for the same meeting.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------

A30298499

| | quorum shall be given in the same manner as for an original meeting and that notice shall state the quorum required at the adjourned meeting. However, no notice need otherwise be given of an
adjourned meeting.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Voting



|23 | 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 not less than 2 per cent. of the Instruments.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|24 | Unless a poll is demanded a declaration by the chairman that a resolution has or has not been passed shall be conclusive evidence of the fact
without proof of the number or proportion of the votes cast in favour of or against it.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|25 | 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.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|26 | A poll demanded on the election of a chairman or on a question of adjournment shall be taken at once.
|-- | -----------------------------------------------------------------------------------------------------



|27 | On a show of hands every person who is present in person and who produces an Instrument or a voting certificate or is a proxy or
representative has one vote. On a poll every such person has one vote in respect of each integral currency unit of the Specified Currency of such Series of Instruments so produced or represented by the voting certificate so produced or for which he
is a proxy or representative. Without prejudice to the obligations of proxies, a person entitled to more than one vote need not use them all or cast them all in the same way.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|28 | 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



|29 | 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.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Minutes



|30 | 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

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

Written Resolution and Electronic Consent



|31 | Subject to the following sentence, a Written Resolution may be contained in one document or in several documents in like form, each signed by
or on behalf of one or more of the Instrumentholders.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For so long as the Instruments are in
the form of a Global Instrument held on behalf of one or more of Euroclear, Clearstream, Luxembourg or Alternative Clearing System, then, in respect of any resolution proposed by the Issuer or the Trustee:



|32 | Electronic Consent: where the terms of the resolution proposed by the Issuer or the Trustee (as the case may be) have been notified to the
Instrumentholders through the relevant Clearing System(s) as provided in sub-paragraphs (i) and/or (ii) below, each of the Issuer and the Trustee shall be entitled to rely upon approval of such resolution given by way of electronic
consents communicated through the electronic communications systems of the relevant Clearing System(s) to the Principal Paying Agent or another specified agent in accordance with their operating rules and procedures by or on behalf of the holders of
not less than 95 per cent. in nominal amount of the Instruments outstanding (the Required Proportion) (Electronic Consent) by close of business on the Relevant Date. The Principal Paying Agent shall confirm
the result of voting on any Electronic Consent in writing to the Issuer and the Trustee (in a form satisfactory to the Trustee), specifying (as of the Relevant Date): (i) the outstanding principal amount of the Instruments and (ii) the
outstanding principal amount of the Instruments in respect of which consent to the resolution has been given in accordance with this provision. The Issuer and the Trustee may act without further enquiry on any such confirmation from the Principal
Paying Agent and shall have no liability or responsibility to anyone as a result of such reliance or action. The Trustee shall not be bound to act on any Electronic Consent in the absence of such a confirmation from the Principal Paying agent in a
form satisfactory to it. Any resolution passed in such manner shall be binding on all Instrumentholders and Couponholders, even if the relevant consent or instruction proves to be defective. The Issuer shall not be liable or responsible to anyone
for such reliance;
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | When a proposal for a resolution to be passed as an Electronic Consent has been made, at least 14 days notice (exclusive of the day on which
the notice is given or deemed to be given and of the day on which affirmative consents will be counted) shall be given to the Instrumentholders through the relevant Clearing System(s). The notice shall specify, in sufficient detail to enable
Instrumentholders to give their consents in relation to the proposed resolution, the method by which their consents may be given (including, where applicable, blocking of their accounts in the relevant clearing system(s)) and the time and date (the
Relevant Date) by which they must be received in order for such consents to be validly given, in each case subject to and in accordance with the operating rules and procedures of the relevant Clearing System(s).
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | If, on the Relevant Date on which the consents in respect of an Electronic Consent are first counted, such consents do not represent the Required
Proportion, the resolution shall be deemed to be defeated. Such determination shall be notified in writing to the other party or parties to the Trust Deed by the Principal Paying Agent. Alternatively, the party proposing such resolution (the
Proposer) may give a

Resolution and/or Electronic Consent.
