A42485973 7 2.3 Covenant to Pay The Issuer shall on any date when any Instruments become due to be redeemed, in whole or in part, unconditionally pay to or to the order of the Trustee in the Contractual Currency, in the case of any Contractual Currency other than Euro, in the principal financial centre for the Contractual Currency and, in the case of Euro, in a city in which banks have access to T2, 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 after a Default), 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 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 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 of the relevant Series. 2.4 Discharge Subject to Clause 2.5 (Payment after a Default), any payment to be made in respect of the Instruments by the 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 the Issuer or the Trustee, as the case may be, except to the extent that there is failure in its subsequent payment to the relevant Instrumentholders 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 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 and the Transfer Agents of the Trustee under this Trust Deed and the Instruments on the terms of the Agency Agreement (with consequential amendments as necessary and except that the Trustee’s liability for the indemnification, remuneration and expenses of the Paying Agents shall be limited to the amounts for the time being held by the Trustee in respect of the Instruments on the terms of this Trust Deed) and thereafter to hold all Instruments and Certificates, and all moneys, documents and records held by them in respect of Instruments and Certificates to the order of the Trustee; or A42485973 8 (ii) to deliver all Instruments and Certificates and all moneys, documents and records held by them in respect of the Instruments and Certificates to the Trustee or as the Trustee directs in such notice; and 2.5.2 by notice in writing to the Issuer, require the Issuer to make all subsequent payments in respect of the Instruments 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 the 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 Certificates The Instruments shall initially be represented by one or more Temporary Global Certificates in the nominal amount of the Tranche being issued. Each Global Certificate shall be printed or typed substantially in the form set out in Part A of Schedule 1 and may be a facsimile. Interests in the Temporary Global Certificate shall be exchangeable for interests in a Permanent Global Certificate upon expiration of the Restricted Period and certification of non-U.S. beneficial ownership. Following termination of the Restricted Period and receipt by the Issuing and Paying Agent of copies of certificates from Euroclear and Clearstream, Luxembourg (if available) certifying that they have received certification of non-U.S. beneficial ownership of 100 per cent. of the aggregate principal amount of each Temporary Global Certificate, the Issuing and Paying Agent or Canadian Paying Agent, as applicable, shall complete a Permanent Global Certificate (being substantially in the form set out in Schedule 1 Part A of the Trust Deed) in an aggregate nominal amount up to that of the relevant Tranche, authenticate it (or cause its agent on its behalf to do so), and deliver the Permanent Global Certificate to the Common Safekeeper which is holding the Temporary Global Certificate representing the Tranche for the time being on behalf of Euroclear and/or Clearstream, Luxembourg together with instructions to the Common Safekeeper to effectuate the same, and, in each case, procure the exchange of interests in such Temporary Global Certificate for interests in an equal nominal amount of such Permanent Global Certificate in accordance with such Temporary Global Certificate. In the case of a total exchange of interests in the Temporary Global Certificate, the Issuing and Paying Agent or Canadian Paying Agent, as applicable, shall cancel or arrange for the cancellation of the Temporary Global Certificate. 3.2 Temporary Global Certificate Legend The Temporary Global Certificate shall bear a legend in substantially the following form:

A42485973 9 “BY ITS ACQUISITION HEREOF, THE HOLDER HEREOF REPRESENTS THAT IT IS NOT A U.S. PERSON, AS DEFINED IN THE U.S. SECURITIES ACT OF 1933 (THE “SECURITIES ACT”), NOR IS IT PURCHASING FOR THE ACCOUNT OR BENEFIT OF A U.S. PERSON, AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT.” 3.3 The Certificates The Certificates shall be printed in accordance with applicable legal and stock exchange requirements substantially in the form set out in Part B of Schedule 1. The Certificates (other than the Global Certificates) shall be endorsed with the Conditions. 3.4 Signature The Instruments and Certificates (other than the Instruments settling in CDS) shall be signed manually or in facsimile by an authorised signatory of the Issuer and the Certificates shall be authenticated by or on behalf of the Registrar. Instruments and Certificates settling in CDS will be signed manually by an authorised signatory of the Issuer (unless CDS agrees that it will accept a facsimile or electronic signature) and such Certificates shall be authenticated manually by or on behalf of the Canadian Paying Agent (unless CDS agrees that it will accept a facsimile or electronic authentication signature). The Issuer may use the facsimile signature of any person who at the date of this Trust Deed is such an authorised signatory even if at the time of issue of any Instruments or Certificates he no longer holds that office. In the case of a Global Certificate which is held under the NSS, the Issuing and Paying Agent or the Registrar shall also instruct the Common Safekeeper to effectuate the same. Certificates so executed and authenticated (and effectuated, if applicable) shall represent binding and valid obligations of the Issuer. Execution in facsimile of any Instruments and any photostatic copying or other duplication of any Global Certificates (in unauthenticated form, but executed manually on behalf of the Issuer as stated above) shall represent binding obligations upon the Issuer in the same manner as if such Certificates were signed manually by such signatories. 3.5 Title The holder of any Instrument whose name is entered in the Register as being entitled to such Instrument 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 The Issuer shall pay any stamp, issue, documentary or other similar taxes and duties payable in the United States of America in respect of the creation, issue and offering of the Instruments and/or Certificates issued by it and the execution or delivery of this Trust Deed. The Issuer shall also indemnify the Trustee and the relevant Instrumentholders from and against all stamp, issue, documentary or other similar 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 to enforce the Issuer’s obligations under this Trust Deed or the relevant Instruments or Certificates. A42485973 10 4.2 Change of Taxing Jurisdiction If the 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 States of America or any political sub-division of the United States of America then the Issuer shall (unless the Trustee otherwise agrees) give the Trustee an undertaking satisfactory to the Trustee in terms corresponding to the terms of Condition 6 with the substitution for, or (as the case may require) the addition to, the references in that Condition to the United States of America of references to that other or additional territory or authority to whose taxing jurisdiction the Issuer has become so subject. In such event this Trust Deed and the relevant Instruments and Certificates 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 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 properly 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 pari passu and rateably; and 5.1.3 thirdly, in payment of any balance to the Issuer for itself. If the Trustee holds any moneys which represent principal, premium or interest in respect of Instruments 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.

Such remuneration shall accrue from day to day from the date of this Trust Deed. However, if any payment to an Instrumentholder of moneys due in respect of any Instrument is improperly withheld or refused, such remuneration shall again accrue as from the date of such withholding or refusal until payment to such Instrumentholder is duly made. 7.2 Extra Remuneration If (i) an Event of Default, Potential Event of Default or Benchmark Event shall have occurred or (ii) in any other case, the Trustee finds it expedient or necessary or is requested by the 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, the Issuer shall pay such additional remuneration as they may agree (and which may be calculated by reference to the Trustee’s normal hourly rates in force from time to time) 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 such matters shall be determined by a financial institution (acting as an expert) selected by the Trustee and approved by the 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 person’s fee shall be shared equally between the Trustee and the Issuer. The determination of the relevant financial institution shall be conclusive and binding on the Issuer, the Trustee and the relevant Instrumentholders. A42485973 14 7.3 Expenses The Issuer shall also, on demand by the Trustee, pay or discharge all costs, charges, liabilities and expenses properly incurred by the Trustee in the preparation and execution of this Trust Deed and the performance of its functions under this Trust Deed including, but not limited to, legal and travelling expenses and any United Kingdom stamp, documentary or other taxes or duties paid by the Trustee in connection with any legal proceedings reasonably brought or contemplated by the Trustee against the Issuer to enforce any provision of this Trust Deed, the relevant Instruments 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.

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 The Issuer 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 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 the 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, charges, 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.

In giving such consent the Trustee may require the Issuer to agree to such modifications or additions to this Trust Deed as the Trustee may deem expedient in the interest of the Instrumentholders. 8.16 Instruments Held by the Issuer etc. In the absence of knowledge or express notice to the contrary, the Trustee may assume without enquiry (other than requesting a certificate under Clause 6.12 (Instruments Held by the Issuer)) that no Instruments are for the time being held by or on behalf of the Issuer or its subsidiary undertakings. 8.17 Legal Opinions The Trustee shall not be responsible to any person for failing to request, require or receive any legal opinion relating to any Instruments or for checking or commenting upon the content of any such legal opinion. 8.18 Programme Limit The Trustee shall not be concerned, and need not enquire, as to whether or not any Instruments are issued in breach of the Programme Limit. 8.19 Events of Default The Trustee may determine whether or not an Event of Default is in its opinion capable of remedy or (in relation to Condition 8(b)) materially prejudicial to the interests of relevant Instrumentholders. Any such determination shall be conclusive and binding on the Issuer and the relevant Instrumentholders. 8.20 Appointment of Independent Financial Adviser In connection with the Trustee’s right to appoint an independent financial adviser pursuant to Clause 8.1 (if applicable), the Trustee: 8.20.1 shall use its reasonable endeavours to identify and appoint the independent financial adviser but shall have no liability to any person if, having used its reasonable endeavours, it is unable to identify and appoint a suitable independent financial adviser; 8.20.2 shall not be responsible for carrying on the role of independent financial adviser itself during the time it is attempting to identify such independent financial adviser or thereafter if it is unable to find such independent financial adviser; and 8.20.3 shall not be required to take any action to find an independent financial adviser unless it has been previously indemnified and/or secured to its satisfaction or expend any of its own funds in the appointment of such an independent financial adviser.

A42485973 19 9 Disapplication and Trustee Liability 9.1 Disapplication Section 1 of the Trustee Act 2000 shall not apply to the duties of the Trustee in relation to the trusts constituted by this Trust Deed. Where there are any inconsistencies between the Trustee Acts and the provisions of this Trust Deed, the provisions of this Trust Deed shall, to the extent allowed by law, prevail and, in the case of any such inconsistency with the Trustee Act 2000, the provisions of this Trust Deed shall constitute a restriction or exclusion for the purposes of that Act. 9.2 Trustee Liability Subject to Sections 750 and 751 of the Companies Act 2006 (if applicable) and notwithstanding anything to the contrary in this Trust Deed, the Instruments or the Agency Agreement, the Trustee shall not be liable to any person for any matter or thing done or omitted in any way in connection with or in relation to this Trust Deed, the Instruments or the Agency Agreement save in relation to its own gross negligence, wilful default or fraud. 10 Waiver and Proof of Default 10.1 Waiver The Trustee may, without the consent of the Instrumentholders and without prejudice to its rights in respect of any subsequent breach, from time to time and at any time, if in its opinion the interests of the Instrumentholders will not be materially prejudiced thereby, waive or authorise, on such terms as seem expedient to it, any breach or proposed breach by the Issuer of this Trust Deed or the Conditions or determine that an Event of Default or Potential Event of Default shall not be treated as such provided that the Trustee shall not do so in contravention of an express direction given by an Extraordinary Resolution or a request made pursuant to Condition 8. No such direction or request shall affect a previous waiver, authorisation or determination. Any such waiver, authorisation or determination shall be binding on the relevant Instrumentholders and, if the Trustee so requires, shall be notified to the Instrumentholders as soon as practicable. 10.2 Proof of Default Proof that the Issuer has failed to pay a sum due to the holder of any one Instrument shall (unless the contrary be proved) be sufficient evidence that it has made the same default as regards all other Instruments which are then payable. 11 Trustee not Precluded from Entering into Contracts The Trustee and any other person, whether or not acting for itself, may acquire, hold or dispose of any Instrument, Certificate or other security (or any interest therein) of the Issuer or any other person, may enter into or be interested in any contract or transaction with any such person and may act on, or as depositary or agent for, any committee or body of holders of any securities of any such person in each case with the same rights as it would have had if the Trustee were not acting as Trustee and need not account for any profit. A42485973 20 12 Modification and Substitution 12.1 Modification The Trustee may agree without the consent of the Instrumentholders to any modification to this Trust Deed of a formal, minor or technical nature or to correct a manifest error. The Trustee may also agree to any other modification to this Trust Deed which is in its opinion not materially prejudicial to the interests of the Instrumentholders of the relevant Series, but such power does not extend to any such modification as is mentioned in the proviso to paragraph 2 of Schedule 3 (Provisions for Meetings of Instrumentholders). In addition, the Trustee shall be obliged to concur with the Issuer in using its reasonable endeavours to effect any Benchmark Amendments in the circumstances and as otherwise set out in Condition 3.10 without the consent or approval of the Instrumentholders, provided that the Trustee shall not be obliged so to concur if in the opinion of the Trustee doing so would impose more onerous obligations upon it or expose it to any additional duties, responsibilities or liabilities or reduce or amend the rights and/or the protective provisions afforded to it in the Conditions and/or any documents to which it is a party (including, for the avoidance of doubt, any supplemental trust deed) in any way. Any such modification, authorisation or waiver shall be binding on the relevant Instrumentholders and if the Trustee so requires, such modification shall be notified to the relevant Instrumentholders as soon as practicable. 12.2 Substitution 12.2.1 The Trustee may, without the consent of the Instrumentholders, agree to the substitution of any other company (the “Substituted Obligor”) in place of the Issuer (or of any previous substitute under this Clause 12) as the principal debtor under this Trust Deed and the relevant Instruments provided that such substitution would not, in the opinion of the Trustee, be materially prejudicial to the interests of the Instrumentholders, and further provided that: (i) a deed is executed or undertaking given by the Substituted Obligor to the Trustee, in form and manner satisfactory to the Trustee, agreeing to be bound by this Trust Deed and the relevant Instruments (with consequential amendments as the Trustee may deem appropriate) as if the Substituted Obligor had been named in this Trust Deed and the relevant Instruments and Certificates as the principal debtor in place of the Issuer; (ii) if the Substituted Obligor is subject generally to the taxing jurisdiction of a territory or any authority of or in that territory with power to tax (the “Substituted Territory”) other than the territory to the taxing jurisdiction of which (or to any such authority of or in which) the 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 6 with the substitution for the references in that Condition to the Issuer’s Territory of references to the Substituted Territory whereupon the Trust Deed, and the relevant Instruments and Certificates shall be read accordingly; (iii) if any two directors of the Substituted Obligor certify that it will be solvent immediately after such substitution, the Trustee need not have regard to the Substituted Obligor’s financial condition, profits or prospects or compare them with those of the Issuer;

A42485973 21 (iv) the Issuer and the Substituted Obligor comply with such other requirements as the Trustee may direct in the interests of the relevant Instrumentholders; and (v) the Trustee is satisfied that (i) the Substituted Obligor has obtained all necessary governmental and regulatory approvals and consents necessary for its assumption of liability as principal debtor in respect of the relevant Instruments in place of the Issuer (or a previous substitute), (ii) all necessary governmental and regulatory approvals and consents necessary for or in connection with the assumption by the Substituted Obligor of its obligations under the relevant Instruments and (iii) such approvals and consents are at the time of substitution in full force and effect. 12.2.2 Release of Substituted Issuer An agreement by the Trustee pursuant to Clause 12.2 (Substitution) shall, if so expressed, release the Issuer (or a previous substitute) from any or all of its obligations under this Trust Deed and the relevant Instruments. 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 On completion of the formalities set out in Clause 12.2 (Substitution), the Substituted Obligor shall be deemed to be named in this Trust Deed and the relevant Instruments and Certificates as the principal debtor in place of the Issuer (or of any previous substitute) and this Trust Deed and the relevant Instruments and Certificates, 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 The Issuer 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 the Issuer to its Instrumentholders in accordance with Condition 13 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 the Issuer 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 (i) the Issuer, appoint anyone to act as an additional Trustee jointly with the Trustee, or (ii) the Issuer appoint anyone to act as a separate Trustee in respect of any issue or: A42485973 22 13.3.1 if the Trustee considers the appointment to be in the interests of the Instrumentholders; or 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 the Issuer and that person remove that person. At the Trustee’s request, the Issuer shall forthwith do all things as may be required to perfect such appointment or removal and the Issuer 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 the Issuer of its intention to make such appointment (and the reason for that) and shall give due consideration to representations made by the Issuer concerning such appointment. Where, as a result of this provision, not all the Instruments have the same Trustee, the provisions of this Trust Deed shall apply in respect of each such Trustee as if each were named as a party to this Trust Deed. 13.4 Competence of a Majority of Trustees If there are more than two Trustees the majority of them shall be competent to perform the Trustee’s functions provided the majority includes a trust corporation. 14 Instruments held in Clearing Systems 14.1 Instruments Held in Clearing Systems So long as any Instruments represented by a Global Certificate are held on behalf of a clearing system, in considering the interests of Instrumentholders, the Trustee may have regard to any information provided to it by such clearing system or its operator as to the identity (either individually or by category) of its accountholders or participants with entitlements to any such Instrument and may consider such interests on the basis that such accountholders or participants were the holder(s) of such Instrument. 14.2 Evidence of Holdings The Trustee and the 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 the relevant clearing system 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 Certificate and if the Trustee or the 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

A42485973 23 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 the Issuer nor the Trustee shall be liable to any person by reason of having accepted as valid or not having rejected any certificate or other document to such effect purporting to be issued by the relevant clearing system and subsequently found to be forged or not authentic. 15 Currency Indemnity 15.1 Currency of Account and Payment The Contractual Currency is the sole currency of account and payment for all sums payable by the Issuer under or in connection with this Trust Deed and the Instruments, including damages. 15.2 Extent of Discharge An amount received or recovered in a currency other than the Contractual Currency (whether as a result of, or of the enforcement of, a judgment or order of a court of any jurisdiction, in the insolvency, winding-up or dissolution of the Issuer), by the Trustee or any Instrumentholder in respect of any sum expressed to be due to it from the Issuer, shall only discharge the 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 or the Instruments, the Issuer shall indemnify the recipient against any loss sustained by it as a result. In any event, the 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 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 or the Instruments or any other judgment or order. 16 Enforcement 16.1 Trustee to enforce Only the Trustee may enforce the rights of the Instrumentholders against the Issuer, whether the same arise under the general law, this Trust Deed, the Instruments or otherwise, and no Instrumentholder shall be entitled to proceed directly against the Issuer unless the Trustee, having become bound to proceed, fails to do so within a reasonable time and such failure is continuing. A42485973 24 16.2 Trustee’s Indemnity The Trustee shall not be bound to take any steps to enforce the performance of any provisions of this Trust Deed or the Instruments or to appoint an independent financial advisor pursuant to the Conditions of the Instruments unless it shall be indemnified and/or secured and/or prefunded by the relevant Instrumentholders to its satisfaction against all proceedings, claims and demands to which it may be liable and against all costs, charges, liabilities and expenses which may be incurred by it in connection with such enforcement or appointment, including the cost of its managements’ time and/or other internal resources, calculated using its normal hourly rates in force from time to time. 16.3 Legal proceedings If the Trustee (or any Instrumentholder where entitled in accordance with this Trust Deed so to do) institutes legal proceedings against the Issuer to enforce any obligations under this Trust Deed, proof in such proceedings that as regards any specified Instrument the Issuer has made default in paying any principal or interest due to the relevant Instrumentholder shall (unless the contrary be proved) be sufficient evidence that the Issuer has made the same default as regards all other Instruments which are then repayable or, as the case may be, in respect of which interest is then payable. 16.4 Powers additional to general powers The powers conferred on the Trustee by this Clause 16 shall be in addition to any powers which may from time to time be vested in the Trustee by general law or as the holder of any Instruments. 17 Communications 17.1 Method Each communication under this Trust Deed shall be made by electronic communication or otherwise in writing. Each communication or document to be delivered to any party under this Trust Deed shall be sent to that party at the electronic address, or address, and marked for the attention of the person (if any), from time to time designated by that party to each other party for the purpose of this Trust Deed. The initial telephone number, electronic address, address and person so designated by the parties under this Trust Deed are set out in the Procedures Memorandum. 17.2 Deemed Receipt Any communication from any party to any other under this Trust Deed shall be effective, (if in writing) when delivered and (if by electronic communication) when the relevant receipt of such communication being read is given, or where no read receipt is requested by the sender, at the time of sending, provided that no delivery failure notification is received by the sender within 24 hours of sending such communication (provided always that any electronic communication to the Trustee shall only be treated as having been received upon confirmation of receipt by the Trustee and an automatically generated “read” or “received” receipt shall not constitute such confirmation); provided that any electronic communication which is received (or deemed to take effect in accordance with the foregoing) after 5:00pm on a business day or on a non-business day in the place of receipt shall be deemed to take effect at the opening of business on the next following business day in such place. Any

A42485973 25 communication delivered to any party under this Trust Deed which is to be sent by electronic communication will be written legal evidence. 18 Governing Law and Jurisdiction 18.1 Governing Law This Trust Deed and any non-contractual obligations arising out of or in connection with it shall be governed by, and construed in accordance with, English law. 18.2 Jurisdiction The courts of England are to have exclusive jurisdiction to settle any disputes that may arise out of or in connection with this Trust Deed or the Instruments and accordingly any legal action or proceedings arising out of or in connection with this Trust Deed or the Instruments (“Proceedings”) may be brought in such courts. The Issuer irrevocably submits to the jurisdiction of such courts and waives any objection to Proceedings in such courts on the ground of venue or on the ground that the Proceedings have been brought in an inconvenient forum. This Clause is for the benefit of each of the Trustee and the relevant Instrumentholders and shall not limit the right of any of them to take Proceedings in any other court of competent jurisdiction nor shall the taking of Proceedings in any one or more jurisdictions preclude the taking of Proceedings in any other jurisdiction (whether concurrently or not). 18.3 Service of Process The Issuer irrevocably appoints National Grid plc of 1-3 Strand, London WC2N 5EH to receive, for it and on its behalf, service of process in any Proceedings in England. Such service shall be deemed completed on delivery to such process agent (whether or not it is forwarded to and received by the Issuer). If for any reason such process agent ceases to be able to act as such or no longer has an address in England the Issuer irrevocably agrees to appoint a substitute process agent acceptable to the Trustee and shall immediately notify the Trustee of such appointment. Nothing shall affect the right to serve process in any other manner permitted by law.

(“NGNA” and, the “Issuer”) has established a Euro Medium Term Note Programme (the “Programme”) for the issuance of up to Euro 8,000,000,000 in aggregate principal amount of debt instruments (the “Instruments”). The Instruments are constituted by an amended and restated Trust Deed (as amended or supplemented from time to time, the “Trust Deed”) dated 4 August 2023 between the Issuer and The Law Debenture Trust Corporation p.l.c. (the “Trustee”, which expression shall include all persons for the time being the trustee or trustees under the Trust Deed) as trustee for the Instrumentholders (as defined below). These terms and conditions (the “Conditions”) include summaries of, and are subject to, the detailed provisions of the Trust Deed which includes the form of the Certificates. An amended and restated Agency Agreement (as amended or supplemented from time to time, the “Agency Agreement”) dated 4 August 2023 has been entered into in relation to the Instruments between the Issuer, the Trustee, The Bank of New York Mellon, London Branch as initial issuing and paying agent, calculation agent and transfer agent, The Bank of New York Mellon SA/NV, Dublin Branch as the registrar and transfer agent, Quintet Private Bank (Europe) S.A. as paying agent and transfer agent, BNY Trust Company of Canada as Canadian paying agent and the other agent(s) named in it. The issuing and paying agent, the paying agent(s), the registrar, the transfer agents, the calculation agent(s) and the Canadian paying agent 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), the “Registrar”, the “Transfer Agents” (which expression shall include the Registrar) the “Calculation Agent(s)” and the “Canadian Paying Agent”.

Instruments of one Specified Denomination are not exchangeable for Instruments of another Specified Denomination. This Instrument is a Fixed Rate Instrument, a Floating Rate Instrument, a Zero Coupon Instrument, or a combination of any of the preceding kinds of Instruments, depending upon the Interest and Redemption Basis specified in the relevant Final Terms.

Beneficial interests in a Temporary Global Certificate will be exchangeable for a Permanent Global Certificate not earlier than 40 days after the issue date upon certification of non-U.S. beneficial ownership. Title to the Instruments shall pass by registration in the register (the “Register”) that the Issuer shall procure to be kept by the Registrar in accordance with the provisions of the Agency Agreement. 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 holder (as defined below) of any Instrument as the absolute owner of that Instrument, whether or not it is overdue and regardless of any notice of ownership, trust or an interest in it, any writing on it (or on the Certificate representing it) or its theft or loss (or that of the related Certificate) and shall not be required to obtain any proof of ownership as to the identity of the holder.

A42485973 43 In these Conditions, “Instrumentholder” and “holder” means the person in whose name an Instrument is registered and capitalised terms have the meanings given to them herein, the absence of any such meaning indicating that such term is not applicable to the Instruments. 2 Status and Negative Pledge 2.1 Status The Instruments 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 shall, subject to such exceptions as are from time to time applicable under the laws of England, rank equally with all other present and future unsecured obligations (other than subordinated obligations, if any) of the Issuer. 2.2 Negative Pledge So long as any Instrument remains outstanding (as defined in the Trust Deed) the Issuer 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, the Issuer’s obligations under the Instruments 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 (in each case, with the agreement of the Issuer) is 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 3.2.1 Interest Payment Dates Each Floating 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, 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 A42485973 44 Final Terms as Specified Interest Payment Dates or, if no Specified Interest Payment Date(s) is/are specified in the relevant Final Terms, Interest Payment Date shall mean each date which falls the number of months or other period shown on this Instrument as the Interest Period after the preceding Interest Payment Date or, in the case of the first Interest Payment Date, after the Interest Commencement Date. 3.2.2 Business Day Convention If any date which is specified to be subject to adjustment in accordance with a Business Day Convention would otherwise fall on a day which is not a Business Day, then, if the Business Day Convention specified is (a) the Floating Rate Convention, such date shall be postponed to the next day which is a Business Day unless it would then fall into the next calendar month, in which event (x) such date shall be brought forward to the immediately preceding Business Day and (y) each subsequent such date shall be the last Business Day of the month in which such date would have fallen had it not been subject to adjustment, (b) the Following Business Day Convention, such date shall be postponed to the next day which is a Business Day, (c) the Modified Following Business Day Convention, such date shall be postponed to the next day which is a Business Day unless it would then fall into the next calendar month, in that event such date shall be brought forward to the immediately preceding Business Day or (d) the Preceding Business Day Convention, such date shall be brought forward to the immediately preceding Business Day. 3.2.3 Rate of Interest for Floating Rate Instruments The Rate of Interest in respect of Floating Rate Instruments for each Interest Accrual Period shall be determined in the manner specified in the relevant Final Terms and the provisions below relating to either ISDA Determination or Screen Rate Determination shall apply, depending upon which is specified on this Instrument. (a) ISDA Determination for Floating Rate Instruments: Where ISDA Determination is specified in the relevant Final Terms as the manner in which the Rate of Interest is to be determined, the Rate of Interest for each Interest Accrual Period shall be determined by the Calculation Agent as a rate equal to the relevant ISDA Rate. For the purposes of this sub-paragraph (a), “ISDA Rate” for an Interest Accrual Period means a rate equal to the Floating Rate which would be determined by the Calculation Agent under a Swap Transaction under the terms of an agreement incorporating the ISDA Definitions and under which: (i) the Floating Rate Option is as specified in the relevant Final Terms; (ii) the Designated Maturity is a period specified in the relevant Final Terms; and (iii) the relevant Reset Date is the first day of that Interest Accrual Period unless otherwise specified in the relevant Final Terms. For the purposes of this sub-paragraph (a), “Floating Rate”, “Calculation Agent”, “Floating Rate Option”, “Designated Maturity”, “Reset Date” and “Swap Transaction” have the meanings given to those terms in the ISDA Definitions. (b) Screen Rate Determination for Floating Rate Instruments not referencing SONIA or CORRA: (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, and unless the Reference Rate in respect of the relevant Series of

A42485973 45 Floating Rate Instruments is specified in the relevant Final Terms as being “SONIA Compounded Index Rate”, “SONIA Compounded Daily Reference Rate” or “CORRA”, the Rate of Interest for each Interest Accrual Period will, subject to Condition 3.10 and 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 (being EURIBOR) which appears or appear, as the case may be, on the Relevant Screen Page (or such replacement page on that service which displays the information) as at 11.00 a.m. Brussels time 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 Issuer shall request the principal Euro-zone office of each of the Reference Banks to provide the Calculation Agent with its offered quotation (expressed as a percentage rate per annum) for the Reference Rate at approximately 11.00 a.m. (Brussels time) on the Interest Determination Date in question. If two or more of the Reference Banks provide the Calculation Agent with such offered quotations, the Rate of Interest for such Interest Accrual Period shall be the arithmetic mean of such offered quotations as determined by the Calculation Agent; and (iii) if paragraph (ii) above applies and the Calculation Agent determines that fewer than two Reference Banks are providing offered quotations, subject as provided below, the Rate of Interest shall be the arithmetic mean of the rates per annum (expressed as a percentage) as communicated to (and at the request of) the Calculation Agent by the Reference Banks or any two or more of them, at which such banks were offered 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 the Euro-zone inter-bank market, 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, 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 A42485973 46 and the Issuer suitable for such purpose) informs the Calculation Agent it is quoting to leading banks in the Euro-zone inter-bank market, 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). (c) Screen Rate Determination for Floating Rate Instruments referencing SONIA: (A) SONIA Compounded Index Rate Where (i) Screen Rate Determination is specified in the relevant Final Terms as the manner in which the Rate of Interest is to be determined and (ii) the Reference Rate is specified in the relevant Final Terms as being “SONIA Compounded Index Rate”, the Rate of Interest for each Interest Accrual Period will, subject to Conditions 3.5 and 3.10, be the SONIA Compounded Index Rate, where: “SONIA Compounded Index Rate” means, with respect to an Interest Accrual Period, the rate of return of a daily compound interest investment during the Observation Period corresponding to such Interest Accrual Period (with the daily Sterling overnight reference rate as reference rate for the calculation of interest) and will be calculated by the Calculation Agent on the relevant Interest Determination Date, as follows, and the resulting percentage will be rounded, if necessary, to the fourth decimal place, with 0.00005 being rounded upwards, ( 𝑆𝑂𝑁𝐼𝐴 𝐶𝑜𝑚𝑝𝑜𝑢𝑛𝑑𝑒𝑑 𝐼𝑛𝑑𝑒𝑥𝐸𝑁𝐷 𝑆𝑂𝑁𝐼𝐴 𝐶𝑜𝑚𝑝𝑜𝑢𝑛𝑑𝑒𝑑 𝐼𝑛𝑑𝑒𝑥𝑆𝑇𝐴𝑅𝑇 − 1) × ( 365 𝑑 ) provided, however, that, and subject to Condition 3.10, if the SONIA Compounded Index Value is not available in relation to any Interest Accrual Period on the Relevant Screen Page or on the Bank of England's website at www.bankofengland.co.uk/boeapps/database/ (or such other page or website as may replace such page for the purposes of publishing the SONIA Compounded Index) for the determination of either or both of SONIA Compounded IndexSTART and SONIA Compounded IndexEND, the Rate of Interest shall be calculated for such Interest Accrual Period on the basis of the SONIA Compounded Daily Reference Rate as set out in Condition 3.2.3(c)(B) as if SONIA Compounded Daily Reference Rate with Observation Shift had been specified in the relevant Final Terms and the Relevant Screen Page shall be deemed to be the Relevant Fallback Screen Page as specified in the relevant Final Terms, where: “d” means the number of calendar days in the relevant Observation Period;

A42485973 47 “London Business Day” means any day on which commercial banks are open for general business (including dealing in foreign exchange and foreign currency deposits) in London; “Observation Period” means, in respect of an Interest Accrual Period, the period from (and including) the date falling “p” London Business Days prior to the first day of such Interest Accrual Period (and the first Observation Period shall begin on and include the date which is “p” London Business Days prior to the Interest Commencement Date) and ending on (but excluding) the date which is “p” London Business Days prior to the relevant Interest Payment Date (or the date falling “p” London Business Days prior to such earlier date, if any, on which the Instruments become due and payable); “p” means, for any Interest Accrual Period the whole number specified in the relevant Final Terms (or, if no such number is so specified, five London Business Days, provided that a number lower than five shall only be so specified with the prior agreement of the Calculation Agent) representing a number of London Business Days; “SONIA Compounded Index” means the index known as the SONIA Compounded Index administered by the Bank of England (or any successor administrator thereof); “SONIA Compounded IndexEND” means the SONIA Compounded Index Value on the last day of the relevant Observation Period; “SONIA Compounded IndexSTART” means the SONIA Compounded Index Value on the first day of the relevant Observation Period; and “SONIA Compounded Index Value” means in relation to any London Business Day, the value of the SONIA Compounded Index as published by authorised distributors on the Relevant Screen Page on such London Business Day or, if the value of the SONIA Compounded Index cannot be obtained from the Relevant Screen Page, as published on the Bank of England’s Website at www.bankofengland.co.uk/boeapps/database/ (or such other page or website as may replace such page for the purposes of publishing the SONIA Compounded Index) on such London Business Day. (B) SONIA Compounded Daily Reference Rate Where (i) Screen Rate Determination is specified in the relevant Final Terms as the manner in which the Rate of Interest is to be determined and (ii) the Reference Rate is specified in the relevant Final Terms as being SONIA Compounded Daily Reference Rate, the Rate of Interest for each Interest Accrual Period will, subject to Conditions 3.5 and 3.10, be the SONIA Compounded Daily Reference Rate as follows, “SONIA Compounded Daily Reference Rate” means, in respect of an Interest Accrual Period, the rate of return of a daily compound interest investment (with the daily Sterling overnight reference rate as reference rate for the calculation of interest) and will be calculated by the Calculation Agent on the relevant Interest Determination Date, as follows, and the resulting percentage will be rounded, if necessary, to the fourth decimal place, with 0.00005 being rounded upwards, A42485973 48 [∏ (1 + 𝑆𝑂𝑁𝐼𝐴i × ni 365 ) 𝑑𝑜 𝑖 = 1 − 1] × 365 𝑑 Where: “London Business Day”, “Observation Period” and “p” have the respective meanings set out under Condition 3.2.3(c)(A); “d” is the number of calendar days in the relevant: (i) Observation Period, where Observation Shift is specified in the relevant Final Terms; or (ii) Interest Accrual Period, where Lag is specified in the relevant Final Terms; “do” is the number of London Business Days in the relevant: (i) Observation Period, where Observation Shift is specified in the relevant Final Terms; or (ii) Interest Accrual Period, where Lag is specified in the relevant Final Terms; “i” is a series of whole numbers from one to do, each representing the relevant London Business Day in chronological order from, and including, the first London Business Day in the relevant: (i) Observation Period, where Observation Shift is specified in the relevant Final Terms to, and including, the last London Business Day in the relevant Observation Period; or (ii) Interest Accrual Period, where Lag is specified in the relevant Final Terms to, and including, the last London Business Day in the relevant Interest Accrual Period; “ni”, for any London Business Day “i”, means the number of calendar days from, and including, such London Business Day “i” up to, but excluding, the following London Business Day; “SONIAi” means, in relation to any London Business Day, the SONIA reference rate in respect of: (i) that London Business Day “i”, where Observation Shift is specified in the relevant Final Terms; or (ii) the London Business Day (being a London Business Day falling in the relevant Observation Period) falling “p” London Business Days prior to the relevant London Business Day “i”, where Lag is specified in the relevant Final Terms; and the “SONIA reference rate”, in respect of any London Business Day, is a reference rate equal to the daily Sterling Overnight Index Average (“SONIA”) rate for such London Business Day as provided by the administrator of SONIA to authorised distributors and as then published on the Relevant Screen Page on the next following London Business Day or, if the Relevant Screen Page is unavailable, as published by authorised distributors on such London Business Day or, if SONIA

A42485973 49 cannot be obtained from the Relevant Screen Page, as published on the Bank of England’s Website at www.bankofengland.co.uk/boeapps/database/ (or such other page or website as may replace such page for the purposes of publishing the SONIA reference rate). (C) Subject to Condition 3.10, where either (i) SONIA Compounded Daily Reference Rate is specified in the relevant Final Terms, or (ii) the SONIA Compounded Index Rate is specified in the relevant Final Terms and Condition 3.2.3(c)(B) applies, if, in respect of any London Business Day, the SONIA reference rate is not available on the Relevant Screen Page or Relevant Fallback Screen Page as applicable, (or as otherwise provided in the relevant definition thereof) or as published on the Bank of England's website at www.bankofengland.co.uk/boeapps/database/ (or such other page or website as may replace such page for the purposes of publishing the SONIA reference rate), such Reference Rate shall be: (i) (i) the Bank of England’s Bank Rate (the “Bank Rate”) prevailing at 5.00 p.m. (or, if earlier, close of business) on the relevant London Business Day; plus (ii) the mean of the spread of the SONIA reference rate to the Bank Rate over the previous five days on which the SONIA reference rate has been published, excluding the highest spread (or, if there is more than one highest spread, one only of those highest spreads) and lowest spread (or, if there is more than one lowest spread, one only of those lowest spreads) to the Bank Rate, or (ii) if such Bank Rate is not available, the SONIA reference rate published on the Relevant Screen Page (or as otherwise provided in the relevant definition thereof) or (if later) as published on the Bank of England’s website at www.bankofengland.co.uk/boeapps/database/ (or such other page or website as may replace such page for the purposes of publishing the SONIA reference rate) for the first preceding London Business Day on which the SONIA reference rate was published on the Relevant Screen Page (or as otherwise provided in the relevant definition thereof) or (if later) as published on the Bank of England’s website at www.bankofengland.co.uk/boeapps/database/ (or such other page or website as may replace such page for the purposes of publishing the SONIA reference rate), and in each case, SONIAi shall be interpreted accordingly. (D) If the Rate of Interest cannot be determined in accordance with the foregoing provisions, but without prejudice to Condition 3.10, the Rate of Interest shall be (i) that determined as at the last preceding Interest Determination Date (though substituting, where a different Margin or Maximum Rate of Interest 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 Rate of Interest or Minimum Rate of Interest relating to the relevant Interest Accrual Period, in place of the Margin or Maximum Rate of Interest or A42485973 50 Minimum Rate of Interest relating to that last preceding Interest Accrual Period) or (ii) if there is no such preceding Interest Determination Date, the initial Rate of Interest which would have been applicable to such Series of Instruments for the first Interest Accrual Period had the Instruments been in issue for a period equal in duration to the scheduled first Interest Accrual Period but ending on (and excluding) the Interest Commencement Date (but applying the Margin and any Maximum Rate of Interest or Minimum Rate of Interest applicable to the first Interest Accrual Period). (E) If the relevant Series of Instruments become due and payable prior to the Maturity Date, the final Interest Determination Date shall, notwithstanding any Interest Determination Date specified in the relevant Final Terms, be deemed to be the date on which such Instruments became due and payable and the Rate of Interest on such Instruments shall, for so long as any such Instrument remains outstanding, be that determined on such date and as if (solely for the purpose of such interest determination) the relevant Interest Accrual Period had been shortened accordingly. (d) Screen Rate Determination for Floating Rate Instruments referencing CORRA Where (i) Screen Rate Determination is specified in the relevant Final Terms as the manner in which the Rate of Interest is to be determined and (ii) the Reference Rate is specified in the relevant Final Terms as being “CORRA”, the Rate of Interest for each Interest Accrual Period will, subject to Conditions 3.5 and 3.10, be Compounded Daily CORRA as follows: “Compounded Daily CORRA” means, in respect of an Interest Accrual Period, the rate of return of a daily compounded interest investment (with the daily Canadian Dollar overnight repurchase rate as the reference rate for the calculation of interest) and will be calculated by the Calculation Agent on the relevant Interest Determination Date, as follows and the resulting percentage will be rounded, if necessary, to the fourth decimal place, with 0.00005 being rounded upwards: ⌈ 𝑑° ∏ 𝑖 = 1 (1 + 𝐶𝑂𝑅𝑅𝐴𝑖−𝑝𝑇𝐵𝐷 × 𝑛𝑖 365 ) − 1⌉ × 365 𝑑 where: “d” means the number of calendar days in the relevant Interest Accrual Period; “d0” is the number of Toronto Business Days in the relevant Interest Accrual Period; “i” means a series of whole numbers from one to d0, each representing the relevant Business Day in chronological order from, and including, the first Toronto Business Day in the relevant Interest Accrual Period to, and including, the last Toronto Business Day in the relevant Interest Accrual Period; “ni” for any Toronto Business Day “i”, means the number of calendar days from, and including, such Business Day “i” to, but excluding, the following such Business Day (which is “i” + 1); “Observation Period” means the period from, and including, the date falling “p” Toronto Business Days prior to the relevant Interest Payment Date (and the first

A42485973 51 Interest Accrual Period shall begin on and include the Issue Date) and ending on, but excluding, the date falling “p” Toronto Business Days prior to the next Interest Payment Date for such Interest Accrual Period (or the date falling “p” Toronto Business Days prior to such earlier date, if any, on which the Instruments become due and payable); “Toronto Business Day” a day on which Schedule I banks under the Bank Act (Canada) are open for business in the city of Toronto, Canada; “CORRAi–pTBD” means the CORRA rate for the Toronto Business Day falling “p” number of Toronto Business Days prior to the relevant Toronto Business Day “i”; and “CORRA” with respect to any Toronto Business Day is a reference rate equal to the daily Canadian Overnight Repo Rate Average rate for that day, as published by the Bank of Canada, as the administrator of such rate (or any successor administrator of such rate) on the website of the Bank of Canada or any successor website, in each case as it appears on the Bank of Canada website at 11:30 am, Toronto time, on the Toronto Business Day immediately following that day. If, in respect of any Toronto Business Day in the relevant Observation Period, the applicable CORRA reference rate is not available or has not otherwise been published by the authorised administrator and there has been no Benchmark Event, then (i) the CORRA reference rate shall be equal to the prevailing Bank of Canada target for the overnight rate as displayed on the Bank of Canada website (or any successor website or official publication of the Bank of Canada) on such Toronto Business Day or, if the Bank of Canada does not target a single rate, the mid-point of the target range set by the Bank of Canada and so published (calculated as the arithmetic average of the upper bound of the target range and the lower bound of the target range, rounded, if necessary, to the nearest second decimal place, 0.005 being rounded upwards), and (ii) if no such overnight rate exists the CORRA reference rate in respect of such Toronto Banking Day shall be the CORRA reference rate in respect of the last Toronto Business Day for which such CORRA reference rate was published by the authorised administrator. In the event that the Rate of Interest cannot be determined in accordance with the foregoing provisions and there has not been a Benchmark Event, the Rate of Interest shall be (i) that determined as at the last preceding Interest Determination Date (though substituting, where a different Margin or Maximum Rate of Interest 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 Rate of Interest or Minimum Rate of Interest relating to the relevant Interest Accrual Period, in place of the Margin or Maximum Rate of Interest or Minimum Rate of Interest relating to that last preceding Interest Accrual Period) or (ii) if there is no such preceding Interest Determination Date, the initial Rate of Interest which would have been applicable to such Series of Instruments for the first Interest Accrual Period had the Instruments been in issue for a period equal in duration to the scheduled first Interest Accrual Period but ending on (and excluding) the Interest Commencement Date (but applying the Margin and any Maximum Rate of Interest or Minimum Rate of Interest applicable to the first Interest Accrual Period). A42485973 52 If the Instruments become due and payable prior to the Maturity Date, the final Interest Determination Date shall, notwithstanding any Interest Determination Date specified in the Final Terms, be deemed to be the date on which the Instruments became due and payable and the Rate of Interest on the Instruments shall, for so long as any such Instruments remain outstanding, be the Rate of Interest determined on such date and as if (solely for the purpose of such interest determination) the relevant Interest Accrual Period had been shortened accordingly. (e) CDOR Rate Determination Where CDOR Rate Determination is specified in the relevant Final Terms as the manner in which the Rate of Interest is to be determined, the Rate of Interest for each Interest Accrual Period shall be the sum of the Margin and the average bid rate (expressed as an annual percentage rate) rounded to the nearest one- hundred-thousandth of one per cent. (with 0.000005 per cent. being rounded up) for bankers’ acceptances in Canadian dollars for the relevant Interest Accrual Period which appears on the Reuters Screen CDOR Page (being the Relevant Screen Page) as of approximately 10:15 a.m. (Toronto time) (or the amended publication time for CDOR, if any, specified by Refinitiv Benchmark Services (UK) Limited (or any successor thereto) as CDOR administrator (the “Administrator”) in accordance with its CDOR methodology, as amended from time to time) on the Interest Determination Date, all as determined by the Calculation Agent; provided that if such rate does not appear on the Relevant Screen Page on such day and such day is on or before the CDOR Cessation Date, then CDOR for such Interest Determination Date will be determined using an Alternative CDOR Page as of an Alternative Time on such day. If no such Alternative CDOR Page is available on such day and such day is on or before the CDOR Cessation Date, CDOR for such Interest Determination Date shall be the average of the bid rates of interest (expressed and rounded as set forth above) for Canadian dollar bankers’ acceptances with maturities equal to the relevant Interest Accrual Period for same day settlement as quoted by such of the Schedule I banks (as defined in the Bank Act (Canada)) as may quote such a rate as of approximately 10:15 a.m., Toronto time, on such Interest Determination Date. As used in the foregoing terms and provisions relating to the determination of CDOR: “Alternative CDOR Page” shall mean the display, designated as page “CDOR” on Bloomberg, or an equivalent service that displays average bid rates of interest for Canadian dollar bankers’ acceptances having the index maturity specified in the applicable supplement; “Alternative Time” for any Alternative CDOR Page, shall mean the time of day at which such Alternative CDOR Page becomes available; and “Reuters Screen CDOR Page” means the display designated as page “CDOR03” on the Refinitiv Benchmark Services (UK) Limited (or such other page as may replace the CDOR page on that service) for purposes of publishing or displaying, among other things, Canadian dollars bankers’ acceptance rates. If CDOR cannot be determined as described above on any Interest Determination Date and such Interest Determination Date is on or before the CDOR Cessation Date, then CDOR for that Interest Determination Date will be

A42485973 53 equal to CDOR in effect for the prior Interest Accrual Period or, in the case of the first Interest Accrual Period during the Floating Rate Period, the most recent rate that could have been determined in accordance with the first sentence of the preceding paragraph had the interest rate been a floating rate during the Fixed Rate Period. Notwithstanding the foregoing, if the Issuer or its designee determines that any of the events described below in paragraphs (i), (ii), (iii), (iv) or (v) have occurred, the Calculation Agent shall substitute for CDOR the alternative rates contemplated by paragraphs (i), (ii), (iii), (iv) or (v), but subject to the provisions of paragraph (vi) as applicable, provided that: (a) the rate set out in paragraph (ii) shall only apply if the rate set out in paragraph (i) is not available, (b) the rate set out in paragraph (iii) shall only apply if neither rate set out in paragraphs (i) or (ii) is available, (c) the rate set out in paragraph (iv) shall only apply if none of the rates set out in paragraphs (i), (ii) or (iii) are available, and (d) the rate set out in paragraph (v) shall only apply if none of the rates set out in paragraphs (i), (ii), (iii) or (iv) are available. (i) CDOR Cessation Date After the CDOR Cessation Date, the Rate of Interest will, subject to the provisions of paragraph (vi) below as applicable, be determined as if references to CDOR were references to Fallback Rate (CORRA) for the Original IBOR Rate Record Day that corresponds to the first Toronto Business Day of a relevant Interest Accrual Period (each a “Reset Date”), as most recently provided or published as at 11:30 a.m., Toronto time, on the related Fallback Observation Day. If neither Bloomberg Index Services Limited (or a successor provider as approved and/or appointed by ISDA from time to time) provides, nor authorised distributors publish, Fallback Rate (CORRA) for that Original IBOR Rate Record Day at, or prior to, 11:30 a.m., Toronto time, on the related Fallback Observation Day and a Fallback Index Cessation Effective Date with respect to Fallback Rate (CORRA) has not occurred, then the rate for that Reset Date will be Fallback Rate (CORRA) as most recently provided or published at that time for the most recent Original IBOR Rate Record Day, notwithstanding that such day does not correspond to the Reset Date. (ii) Fallback Rate (CORRA) Upon the occurrence of a Fallback Index Cessation Event with respect to Fallback Rate (CORRA), the rate for a Reset Date for a relevant Interest Accrual Period in respect of which the Fallback Observation Day occurs on or after the Fallback Index Cessation Effective Date with respect to Fallback Rate (CORRA) will be the Canadian Overnight Repo Rate Average (“CORRA”) administered by the Bank of Canada (or any successor administrator), to which the Calculation Agent shall apply the most recently published spread, as at the Fallback Index Cessation Effective Date with respect to Fallback Rate (CORRA), referred to in the definition of “Fallback Rate (CORRA)” after making such adjustments to CORRA as are necessary to account for any difference in term structure or tenor of CORRA by comparison to Fallback Rate (CORRA) and by reference to the Bloomberg IBOR Fallback Rate Adjustments Rule Book. A42485973 54 (iii) CORRA If neither the administrator nor authorised distributors provide or publish CORRA and a Fallback Index Cessation Effective Date with respect to CORRA has not occurred, then, in respect of any day for which CORRA is required, references to CORRA will be deemed to be references to the last provided or published CORRA. If a Fallback Index Cessation Effective Date occurs with respect to each of Fallback Rate (CORRA) and CORRA, then the rate for a Reset Date for a relevant Interest Accrual Period in respect of which the Fallback Observation Day occurs on or after the Fallback Index Cessation Effective Date with respect to Fallback Rate (CORRA) (or, if later, the Fallback Index Cessation Effective Date with respect to CORRA) will be the CAD Recommended Rate, to which the Calculation Agent shall apply the most recently published spread, as at the Fallback Index Cessation Effective Date with respect to Fallback Rate (CORRA), referred to in the definition of “Fallback Rate (CORRA)” after making such adjustments to the CAD Recommended Rate as are necessary to account for any difference in term structure or tenor of the CAD Recommended Rate by comparison to Fallback Rate (CORRA) and by reference to the Bloomberg IBOR Fallback Rate Adjustments Rule Book. (iv) CAD Recommended Rate If there is a CAD Recommended Rate before the end of the first Toronto Business Day following the Fallback Index Cessation Effective Date with respect to Fallback Rate (CORRA) (or, if later, the end of the first Toronto Business Day following the Fallback Index Cessation Effective Date with respect to CORRA) but neither the administrator nor authorised distributors provide or publish the CAD Recommended Rate and a Fallback Index Cessation Effective Date with respect to it has not occurred, then, in respect of any day for which the CAD Recommended Rate is required, references to the CAD Recommended Rate will be deemed to be references to the last provided or published CAD Recommended Rate. If there is no CAD Recommended Rate before the end of the first Toronto Business Day following the Fallback Index Cessation Effective Date with respect to Fallback Rate (CORRA) (or, if later, the end of the first Toronto Business Day following the Fallback Index Cessation Effective Date with respect to CORRA); or there is a CAD Recommended Rate and a Fallback Index Cessation Effective Date subsequently occurs with respect to it, then the rate for a Reset Date for a relevant Interest Accrual Period in respect of which the Fallback Observation Day occurs on or after the Fallback Index Cessation Effective Date with respect to Fallback Rate (CORRA) (or, if later, the Fallback Index Cessation Effective Date with respect to CORRA) or the Fallback Index Cessation Effective Date with respect to the CAD Recommended Rate (as applicable) will be the Bank of Canada's Target for the Overnight Rate as set by the Bank of Canada and published on the Bank of Canada's Website (the “BOC Target Rate”), to which the Calculation Agent shall apply the most recently published spread, as at the Fallback Index Cessation Effective Date with respect to Fallback Rate

A42485973 55 (CORRA), referred to in the definition of “Fallback Rate (CORRA)” after making such adjustments to the BOC Target Rate as are necessary to account for any difference in term structure or tenor of the BOC Target Rate by comparison to Fallback Rate (CORRA) and by reference to the Bloomberg IBOR Fallback Rate Adjustments Rule Book. (v) BOC Target Rate If neither the administrator nor authorised distributors provide or publish the BOC Target Rate and a Fallback Index Cessation Effective Date with respect to the BOC Target Rate has not occurred, then, in respect of any day for which the BOC Target Rate is required, references to the BOC Target Rate will be deemed to be references to the last provided or published BOC Target Rate. (vi) Notwithstanding the foregoing, in connection with the implementation of an Applicable Fallback Rate, the Issuer or its designee may make such adjustments to the Applicable Fallback Rate or the spread thereon, as well as the business day convention, Reset Dates and related provisions and definitions including the Fallback Observation Day, in each case that are consistent with accepted market practice for the debt obligations such as the Instruments in such circumstances.

(f) Linear Interpolation A42485973 58 Where Linear Interpolation is specified in the relevant Final Terms as applicable in respect of an Interest Accrual Period, the Rate of Interest for such Interest Accrual Period shall be calculated by the Calculation Agent by straight line linear interpolation by reference to two rates based on the relevant Reference Rate (where Screen Rate Determination is specified in the relevant Final Terms as applicable) or the relevant Floating Rate Option (where ISDA Determination is specified in the relevant Final Terms as applicable), one of which shall be determined as if the Applicable Maturity were the period of time for which rates are available next shorter than the length of the relevant Interest Accrual Period and the other of which shall be determined as if the Applicable Maturity were the period of time for which rates are available next longer than the length of the relevant Interest Accrual Period provided however that if there is no rate available for the period of time next shorter or, as the case may be, next longer, then the Issuer shall determine, or shall appoint an agent to determine, such rate at such time and by reference to such sources as it determines appropriate, acting in good faith and in a commercially reasonable manner. “Applicable Maturity” means: (a) in relation to Screen Rate Determination, the period of time designated in the Reference Rate and (b) in relation to ISDA Determination, the Designated Maturity. 3.3 Zero Coupon Instruments Where an Instrument, the Interest Basis of which is specified to be Zero Coupon, is repayable prior to the Maturity Date and is not paid when due, the amount due and payable prior to the Maturity Date shall be the Early Redemption Amount of such Instrument. As from the Maturity Date, the Rate of Interest for any overdue principal of such an Instrument shall be a rate per annum (expressed as a percentage) equal to the Amortisation Yield (as defined in Condition 4.4.1(b)). 3.4 Accrual of Interest Interest shall cease to accrue on each Instrument on the due date for redemption unless, upon due presentation, payment is improperly withheld or refused, in which event interest shall continue to accrue (as well after as before judgment) at the Rate of Interest in the manner provided in this Condition 3 to the Relevant Date (as defined in Condition 6). 3.5 Margin, Maximum/Minimum Rates of Interest, Redemption Amounts and Rounding (i) If any Margin is specified in the relevant Final Terms (either (x) generally, or (y) in relation to one or more Interest Accrual Periods), an adjustment shall be made to all Rates of Interest, in the case of (x), or the Rates of Interest for the specified Interest Accrual Periods, in the case of (y), calculated in accordance with Condition 3.2.3(b), Condition 3.2.3(c), Conditions 3.2.3(d) or Condition 3.2.3(e) above, as applicable, by adding (if a positive number) or subtracting (if a negative number) the absolute value of such Margin, subject always to the next paragraph. (ii) If any Maximum or Minimum Rate of Interest, or Redemption Amount is specified in the relevant Final Terms, then any Rate of Interest, or Redemption Amount shall be subject to such maximum or minimum, as the case may be.

Where any Interest Period comprises two or more Interest Accrual Periods, the amount of interest payable per Calculation Amount in respect of such Interest Period shall be the sum of the Interest Amounts payable in respect of each of those Interest Accrual Periods. In respect of any other period for which interest is required to be calculated, the provisions above shall apply save that the Day Count Fraction shall be for the period for which interest is required to be calculated. 3.7 Determination and Publication of Rates of Interest, Interest Amounts, Final Redemption Amounts, Early Redemption Amounts and Optional Redemption Amounts The Calculation Agent shall as soon as practicable on each Interest Determination Date or such other time on such date as the Calculation Agent may be required to calculate any rate or amount, obtain any quotation or make any determination or calculation, determine such rate and calculate the Interest Amounts for the relevant Interest Accrual Period, calculate the Redemption Amount, obtain such quote or make such determination or calculation, as the case may be, and cause the Rate of Interest and the Interest Amounts for each Interest Accrual Period and the relevant Interest Payment Date and, if required to be calculated, the Final Redemption Amount, Early Redemption Amount, or any Optional Redemption Amount to be notified to the Trustee, the Issuer, each of the Paying Agents, the Instrumentholders, any other Calculation Agent appointed in respect of the Instruments that is to make a further calculation upon receipt of such information and, if the Instruments are listed on a stock exchange and the rules of such exchange so require, such exchange as soon as possible after their determination but in no event later than (i) the commencement of the relevant Interest Period, if determined prior to such time, in the case of notification to such exchange of a Rate of Interest and Interest Amount, or (ii) in all other cases, the second Business Day after such determination. Where any Interest Payment Date or Interest Period Date is subject to adjustment pursuant to Condition 3.2.2, the Interest Amounts and the Interest Payment Date so published may subsequently be amended (or appropriate alternative arrangements made with the consent of the Trustee by way of adjustment) without notice in the event of an extension or shortening of the Interest Period. If the Instruments become due and payable under Condition 8, the accrued interest and the Rate of Interest payable in respect of the Instruments shall, subject, in the case of each of the SONIA Compounded Index Rate and the SONIA Compounded Daily Reference Rate, to Condition 3.2.3(c)(E), and in the case of CORRA, to the last paragraph of Condition 3.2.3(d), 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.

In making such determination and any other determination pursuant to this Condition 3.10, the Issuer shall act in good faith and in a commercially reasonable manner. In the absence of fraud, the Independent Adviser shall have no liability whatsoever to the Trustee, the Paying Agents, or the Instrumentholders for any advice given to the Issuer in connection with any determination made by the Issuer, pursuant to this Condition 3.10. If the Issuer fails to determine a Successor Rate or, failing which, an Alternative Rate in accordance with this Condition 3.10.1 prior to the date three Business Days prior to the relevant Interest Determination Date, the Rate of Interest applicable to the next succeeding Interest Accrual Period shall be equal to the Rate of Interest last determined in relation to the Instruments in respect of the immediately preceding Interest Accrual Period. If there has not been a first Interest Payment Date, the Rate of Interest shall be the initial Rate of Interest. 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 shall be substituted in place of the Margin or Maximum or Minimum Rate of Interest relating to that last preceding Interest Accrual Period. For the avoidance of doubt, this paragraph shall apply to the relevant next succeeding Interest Accrual Period only and any subsequent Interest Accrual Periods are subject to the subsequent operation of, and to adjustment as provided in, the first paragraph of this Condition 3.10. 3.10.2 Successor Rate or Alternative Rate If the Issuer, following consultation with the Independent Adviser or acting alone, as the case may be, determines that: (a) there is a Successor Rate, then such Successor Rate and any applicable Adjustment Spread shall subsequently be used in place of the Original

A42485973 65 Reference Rate to determine the Rate of Interest (or the relevant component part thereof) for all future payments of interest on the Instruments (subject to the operation of this Condition 3.10); or (b) there is no Successor Rate but that there is an Alternative Rate, then such Alternative Rate and any applicable Adjustment Spread shall subsequently be used in place of the Original Reference Rate to determine the Rate of Interest (or the relevant component part thereof) for all future payments of interest on the Instruments (subject to the operation of this Condition 3.10). 3.10.3 Adjustment Spread The Adjustment Spread (or the formula or methodology for determining the Adjustment Spread) shall be applied to the Successor Rate or the Alternative Rate (as the case may be). If the Issuer, following consultation with the Independent Adviser is unable to determine the quantum of, or a formula or methodology for determining, such Adjustment Spread, then the Successor Rate or Alternative Rate (as applicable) will apply without an Adjustment Spread. 3.10.4 Benchmark Amendments If any Successor Rate or Alternative Rate and, in either case, any applicable Adjustment Spread is determined in accordance with this Condition 3.10 and the Issuer, following consultation with the Independent Adviser, determines (i) that amendments to these Conditions, the Agency Agreement and/or the Trust Deed are necessary to ensure the proper operation of such Successor Rate or Alternative Rate and/or (in either case) any applicable Adjustment Spread (provided that the amendments do not, without the consent of the Calculation Agent, impose more onerous obligations upon it or expose it to any additional duties, responsibilities or liabilities or reduce or amend the protective provisions attached to it) (such amendments, the “Benchmark Amendments”) and (ii) the terms of the Benchmark Amendments, then the Issuer shall, subject to giving notice thereof in accordance with Condition 3.10.5, without any requirement for the consent or approval of Instrumentholders, vary these Conditions, the Agency Agreement and/or the Trust Deed to give effect to such Benchmark Amendments with effect from the date specified in such notice. At the request of the Issuer, but subject to receipt by the Trustee and the Issuing and Paying Agent of a certificate signed by two Directors of the Issuer pursuant to Condition 3.10.5, the Trustee and the Issuing and Paying Agent shall (at the expense and direction of the Issuer), without any requirement for the consent or approval of the Instrumentholders, be obliged to concur with the Issuer in using its reasonable endeavours to effect any Benchmark Amendments (including, inter alia, by the execution of a deed supplemental to or amending the Trust Deed) and the Trustee and the Issuing and Paying Agent shall not be liable to any party for any consequences thereof, provided that the Trustee and the Issuing and Paying Agent shall not be obliged so to concur if in the opinion of the Trustee or the Issuing and Paying Agent doing so would impose more onerous obligations upon it or expose it to any additional duties, responsibilities or liabilities or reduce or amend the rights and/or the protective provisions afforded to it in these Conditions and/or any documents to which it is a party (including, for the avoidance of doubt, any supplemental trust deed) in any way. In connection with any such variation in accordance with this Condition 3.10.4, the Issuer shall comply with the rules of any stock exchange on which the Instruments are for the time being listed or admitted to trading. A42485973 66 3.10.5 Notices, etc. Any Successor Rate, Alternative Rate, Adjustment Spread and the specific terms of any Benchmark Amendments determined under this Condition 3.10 will be notified promptly by the Issuer to the Trustee, the Calculation Agent, the Paying Agents and, in accordance with Condition 13, the Instrumentholders. Such notice shall be irrevocable and shall specify the effective date of the Benchmark Amendments, if any. No later than notifying the Trustee and the Issuing and Paying Agent of the same, the Issuer shall deliver to the Trustee and the Issuing and Paying Agent a certificate signed by two Directors of the Issuer: (a) confirming (i) that a Benchmark Event has occurred, (ii) the Successor Rate or, as the case may be, the Alternative Rate, (iii) any applicable Adjustment Spread and (iv) the specific terms of the Benchmark Amendments (if any), in each case as determined in accordance with the provisions of this Condition 3.10; and (b) certifying that the Benchmark Amendments (if any) are necessary to ensure the proper operation of such Successor Rate or Alternative Rate and (in either case) any applicable Adjustment Spread. The Trustee and the Issuing and Paying Agent shall be entitled to rely on such certificate (without enquiry or liability to any person) as sufficient evidence thereof. The Successor Rate or Alternative Rate and the Adjustment Spread and the Benchmark Amendments (if any) specified in such certificate will (in the absence of manifest error in the determination of the Successor Rate or Alternative Rate and the Adjustment Spread and the Benchmark Amendments (if any) and without prejudice to the Trustee’s and the Issuing and Paying Agent’s ability to rely on such certificate as aforesaid) be binding on the Issuer, the Trustee, the Calculation Agent, the Paying Agents and the Instrumentholders. 3.10.6 Survival of Original Reference Rate Without prejudice to the obligations of the Issuer under Condition 3.10.1, 3.10.2, 3.10.3 and 3.10.4, the Original Reference Rate and the fallback provisions provided for in Condition 3.2.3 will continue to apply unless and until the Issuer determines that a Benchmark Event has occurred and the relevant Paying Agent has been notified of the Successor Rate or the Alternative Rate (as the case may be), and any Adjustment Spread and Benchmark Amendments, in accordance with Condition 3.10.5. 3.10.7 Definitions As used in this Condition 3.10: “Adjustment Spread” means either (a) a spread (which may be positive, negative or zero) or (b) a formula or methodology for calculating a spread, in each case to be applied to the Successor Rate or the Alternative Rate (as the case may be) and is the spread, formula or methodology which: (a) in the case of a Successor Rate, is formally recommended in relation to the replacement of the Original Reference Rate with the Successor Rate by any Relevant Nominating Body; or (if no such recommendation has been made, or in the case of an Alternative Rate) (b) the Issuer, following consultation with the Independent Adviser or acting alone, as the case may be, determines is customarily applied to the relevant Successor Rate or the Alternative Rate (as the case may be) in international debt capital markets transactions to produce an industry-accepted replacement rate for the Original Reference Rate; or (if the Issuer determines that no such spread is

A42485973 67 customarily applied) the Issuer, following consultation with the Independent Adviser or acting alone, as the case may be, determines is recognised or acknowledged as being the industry standard for over-the-counter derivative transactions which reference the Original Reference Rate, where such rate has been replaced by the Successor Rate or the Alternative Rate (as the case may be). “Alternative Rate” means an alternative benchmark or screen rate which the Issuer following consultation with the Independent Adviser, determines is customarily applied in international debt capital markets transactions for the purposes of determining floating rates of interest (or the relevant component part thereof) in the same Specified Currency as the Instruments. “Benchmark Amendments” has the meaning given to it in Condition 3.10.4. “Benchmark Event” means: (1) the Original Reference Rate ceasing to be published for a period of at least five Business Days or ceasing to exist; or (2) a public statement by the administrator of the Original Reference Rate that it has ceased or that it will cease publishing the Original Reference Rate permanently or indefinitely (in circumstances where no successor administrator has been appointed that will continue publication of the Original Reference Rate); or (3) a public statement by the supervisor of the administrator of the Original Reference Rate that the Original Reference Rate has been or will be permanently or indefinitely discontinued; or (4) a public statement by the supervisor of the administrator of the Original Reference Rate as a consequence of which the Original Reference Rate will be prohibited from being used either generally, or in respect of the Instruments; or (5) the making of a public statement by the supervisor of the administrator of the Original Reference Rate that the Original Reference Rate is or will be (or is or will be deemed by such supervisor to be) no longer representative of its relevant underlying market; or (6) it has or will become unlawful for any Paying Agent, the Calculation Agent or the Issuer to calculate any payments due to be made to any Instrumentholders using the Original Reference Rate, provided that the Benchmark Event shall be deemed to occur (a) in the case of sub- paragraphs (2) and (3) above, on the date of the cessation of publication of the Original Reference Rate or the discontinuation of the Original Reference Rate, respectively, (b) in the case of sub-paragraph (4) above, on the date of the prohibition of use of the Original Reference Rate and (c) in the case of sub-paragraph (5) above, on the date with effect from which the Original Reference Rate will no longer be (or will be deemed by the relevant supervisor to no longer be) representative of its relevant underlying market and which is specified in the relevant public statement, and, in each case, not the date of the relevant public statement. “Independent Adviser” means an independent financial institution of international repute or an independent financial adviser with appropriate expertise appointed by the Issuer at its own expense under Condition 3.10.1 and notified in writing to the Trustee. A42485973 68 “Original Reference Rate” means the originally-specified benchmark or screen rate (as applicable) used to determine the Rate of Interest (or any component part thereof) on the Instruments or, if applicable, any other Successor or Alternative Rate (or any component part thereof) determined and applicable to the Instruments pursuant to the earlier operation of Condition 3.10. “Relevant Nominating Body” means, in respect of a benchmark or screen rate (as applicable): (i) the central bank for the currency to which the benchmark or screen rate (as applicable) relates, or any central bank or other supervisory authority which is responsible for supervising the administrator of the benchmark or screen rate (as applicable); or (ii) any working group or committee sponsored by, chaired or co-chaired by or constituted at the request of (a) the central bank for the currency to which the benchmark or screen rate (as applicable) relates, (b) any central bank or other supervisory authority which is responsible for supervising the administrator of the benchmark or screen rate (as applicable), (c) a group of the aforementioned central banks or other supervisory authorities or (d) the Financial Stability Board or any part thereof. “Successor Rate” means a successor to or replacement of the Original Reference Rate which is formally recommended by any Relevant Nominating Body. 4 Redemption, Purchase and Options 4.1 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. 4.2 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 6, and such requirement to pay such additional amounts arises by reason of a change in the laws of the United States of America or any political sub-division of the United States of America or any authority in or of the United States of America having power to tax or in the interpretation or application of the laws of the United States of America or any political sub- division of the United States of America or any authority in or of the United States of America having power to tax 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 60 days’ notice to the Instrumentholders in accordance with Condition 13, redeem all, but not some only, of the Instruments at their Early Redemption Amount together with interest accrued to the date of redemption. Prior to the publication of any notice of redemption pursuant to this Condition 4.2, the Issuer shall deliver to the Trustee a certificate signed by two directors of the Issuer stating that the requirement referred to above cannot be avoided by the Issuer taking reasonable measures available to it and the Trustee shall be entitled to accept such certificate as sufficient evidence of the satisfaction of the condition

A42485973 69 precedent set out above in which event it shall be conclusive and binding on Instrumentholders. 4.3 Purchases The Issuer and any of its Subsidiaries may at any time purchase Instruments in the open market or otherwise at any price. “Subsidiary” means any corporation a majority of the outstanding voting stock of which is owned, directly or indirectly, by the Issuer. 4.4 Early Redemption 4.4.1 Zero Coupon Instruments (a) The Early Redemption Amount payable in respect of any Zero Coupon Instrument upon redemption of such Instrument pursuant to Condition 4.2 or upon it becoming due and payable as provided in Condition 8 shall be the Amortised Face Amount (calculated as provided below) of such Instrument. (b) Subject to the provisions of sub-paragraph (c) below, the Amortised Face Amount of any such Instrument shall be the scheduled Final Redemption Amount of such Instrument on the Maturity Date discounted at a rate per annum (expressed as a percentage) equal to the Amortisation Yield (which, if none is specified in the relevant Final Terms, shall be such rate as would produce an Amortised Face Amount equal to the issue price of the Instruments if they were discounted back to their issue price on the Issue Date) compounded annually. (c) If the Early Redemption Amount payable in respect of any such Instrument upon its redemption pursuant to Condition 4.2 or, if applicable, Condition 4.5 or upon it becoming due and payable as provided in Condition 8, is not paid when due, the Early Redemption Amount due and payable in respect of such Instrument shall be the Amortised Face Amount of such Instrument as defined in sub-paragraph (b) above, except that such sub-paragraph shall have effect as though the reference in that sub-paragraph to the date on which the Instrument becomes due and payable was replaced by a reference to the Relevant Date as defined in Condition 6. The calculation of the Amortised Face Amount in accordance with this sub-paragraph shall continue to be made (as well after as before judgment) until the Relevant Date, unless the Relevant Date falls on or after the Maturity Date, in which case the amount due and payable shall be the scheduled Final Redemption Amount of such Instrument on the Maturity Date together with any interest that may accrue in accordance with Condition 3.2. Where such calculation is to be made for a period of less than one year, it shall be made on the basis of the Day Count Fraction specified in the relevant Final Terms. 4.4.2 Other Instruments The Early Redemption Amount payable in respect of any Instrument (other than Instruments described in Condition 4.4.1), upon redemption of such Instrument pursuant to this Condition 4.4 or upon it becoming due and payable as provided in Condition 8, shall be the Final Redemption Amount unless otherwise specified in the relevant Final Terms. 4.5 Redemption at the Option of the Issuer and Exercise of Issuer’s Options 4.5.1 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 A42485973 70 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 4.5.1. 4.5.2 If Call Option is specified in the relevant Final Terms, the Issuer may, unless an Exercise Notice has been given pursuant to Condition 4.6, 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 the Issuer’s option, the notice to Instrumentholders shall also specify the nominal amount of Instruments drawn and the holder(s) of such 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. 4.5.3 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 4.6, 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) (A) 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) and confirmed in writing by the Issuer to the Trustee expressed as a percentage (rounded to

A42485973 71 the nearest five decimal places, 0.000005 being rounded upwards) at which the Gross Redemption Yield to maturity on such Instrument (or, if a Par Call Commencement Date is specified in the relevant Final Terms, the Gross Redemption Yield to the Par Call Commencement Date) on the Determination Date specified in the relevant 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 relevant Final Terms; or (B) if Canada Yield Price is specified in the relevant Final Terms, (I) at any time prior to the Par Call Commencement Date, the Canada Yield Price and (II) at any time on or after the Par Call Commencement Date, but prior to the Maturity Date, the nominal amount of the Instruments. 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 (or the Instruments to be redeemed will be selected by the Canadian Paying Agent in such manner as the Canadian Paying Agent deems appropriate and as approved by the Trustee), subject to compliance with any applicable laws, listing authority and stock exchange requirements. In this Condition: “Canada Yield Price” means the price, calculated on the business day preceding the redemption date of the Instruments (the “Yield Determination Date”) equal to the net present value of all scheduled payments of outstanding principal and interest on the Instruments to be redeemed (not including any portion of the payment of interest accrued as of the redemption date) from the redemption date of the Instruments to be redeemed to the Par Call Commencement Date specified in the relevant Final Terms (and assuming, for this purpose, that the Instruments are scheduled to mature on the Par Call Commencement Date) using as a discount rate the Government of Canada Yield plus any applicable Redemption Margin specified in the relevant Final Terms. “Government of Canada Yield” means with respect to any redemption date, the arithmetic average (rounded to the nearest 1/100 of 1 per cent.) of the yield to maturity, provided by two major Canadian investment dealers selected by the Issuer as at noon (Toronto time) on the Yield Determination Date, as the yields which a non-callable Government of Canada bond would carry if issued, in Canadian dollars in Canada, at 100 per cent. of its principal amount on such date with a term to maturity which most closely approximates the remaining term to the Par Call Commencement Date. A42485973 72 “Gross Redemption Yield” means a yield calculated in accordance with generally accepted market practice at such time, as advised to the Trustee by the Financial Adviser. 4.6 Redemption at the Option of Instrumentholders If Put Option is specified in the relevant Final Terms, the Issuer shall, at the option of any Instrumentholder, upon such Instrumentholder giving not less than 15 nor more than 30 days’ notice to the Issuer (or such other notice period as may be specified in the relevant Final Terms) redeem such Instrument on the Optional Redemption Date(s) (as specified in the relevant Final Terms) at its Optional Redemption Amount (as specified in the Final Terms) together with interest accrued to the date fixed for redemption. To exercise such option (which must be exercised on an Option Exercise Date) the holder must deposit the Certificate representing the Instrument(s) with the Registrar or any Transfer Agent at its specified office, together with a duly completed option exercise notice (“Exercise Notice”) in the form obtainable from any Paying Agent, the Registrar or any Transfer Agent (as applicable) within the Instrumentholders’ Option Period (as specified in the Final Terms). No Instrument so deposited and option exercised may be withdrawn (except as provided in the Agency Agreement) without the prior consent of the Issuer. 4.7 Cancellation All Instruments redeemed pursuant to any of the foregoing provisions will be cancelled forthwith. All Instruments purchased by or on behalf of the Issuer or any of its Subsidiaries may, at the option of the Issuer be held by or may be surrendered for cancellation, but may not be resold and when held by the Issuer or any of its Subsidiaries shall not entitle the holder to vote at any meeting of Instrumentholders and shall not be deemed to be outstanding for the purposes of calculating quorums at meetings of Instrumentholders or for the purposes of Condition 10. Instruments may be surrendered for cancellation by surrendering the Certificate representing such Instruments to the Registrar and, in each case, if so surrendered, shall, together with all Instruments redeemed by the Issuer, be cancelled forthwith. 5 Payments 5.1 Payments in respect of Instruments Payments of principal in respect of Instruments shall be made against presentation and surrender of the relevant Certificates at the specified office of any of the Transfer Agents or of the Registrar and in the manner provided in paragraph (ii) below. Interest on Instruments shall be paid to the person shown on the Register at the close of business on the fifteenth day before the due date for payment thereof (the “Record Date”). Payments of interest on each Instrument shall be made in the relevant currency by cheque drawn on a bank and mailed to the holder (or to the first named of joint holders) of such Instrument at its address appearing in the Register. Upon application by the holder to the specified office of the Registrar or any Transfer Agent before the Record Date, such payment of interest may be made by transfer to an account in the relevant currency maintained by the payee with a bank. 5.2 Payments subject to Fiscal Laws etc. All payments are subject in all cases to (i) any applicable fiscal or other laws, regulations and directives, but without prejudice to the provisions of Condition 6 and (ii) any withholding or deduction 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 to 1474 (inclusive) of the Code, any United States Treasury Regulations or

A42485973 73 agreements thereunder, any official interpretations thereof, any successor, substitute or similar legislation or law or any law implementing an intergovernmental approach thereto. No commission or expenses shall be charged to the Instrumentholders in respect of such payments. 5.3 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, the Registrar, the Transfer 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, the Registrar, any Transfer Agent or the Calculation Agent and to appoint additional or other Paying Agents or Transfer Agents, provided that the Issuer shall at all times maintain (a) an Issuing and Paying Agent, (b) a Paying Agent (which may be the Issuing and Paying Agent) having its specified office in a major European city, (c) a Calculation Agent where the Conditions so require one, (d) so long as the Instruments are listed on any stock exchange or admitted to listing by any other relevant authority, a Paying Agent having a specified office in such place as may be required by the rules and regulations of any other relevant stock exchange or other relevant authority and (e) a Registrar and a Transfer Agent. As used in these Conditions, the terms “Issuing and Paying Agent”, “Calculation Agent”, “Registrar”, “Transfer Agent” and “Paying Agent” include any additional or replacement Issuing and Paying Agent, Calculation Agent, Registrar, Transfer Agent or Paying Agent appointed under this Condition. Notice of any such change or any change of any specified office shall promptly be given to the Instrumentholders in accordance with Condition 13. 5.4 Non-business days If any date for payment in respect of any Instrument 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 place in which the specified office of the Registrar is located, in such jurisdictions as shall be specified as “Financial Centres” in the relevant Final Terms and: 5.4.1 (in the case of a payment in a currency other than Euro) where payment is to be made by transfer to an account maintained with a bank in the relevant currency, on which foreign exchange transactions may be carried on in the relevant currency in the principal financial centre of the country of such currency; or 5.4.2 (in the case of a payment in Euro) which is a TARGET Business Day. 6 Taxation All payments of principal and interest by or on behalf of the Issuer in respect of the Instruments 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 States of America or any political sub-division of the United States of America or any authority in or of the United States of America 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 payment to the Instrumentholders of the amounts which would otherwise have been receivable in respect of the Instruments had no withholding or deduction been made, except that no such additional amounts A42485973 74 shall be payable in respect of any Instrument (or the Certificate representing it) held or 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 the Certificate representing such Instrument) by reason of having some connection with the United States of America other than the mere holding of such Instrument (or the Certificate representing such Instrument); or (b) by or on behalf of a person who would not be liable or subject to such deduction or withholding by making a declaration of non-residence or other claim for exemption to a tax authority; or (c) more than 30 days after the Relevant Date except to the extent that the holder would have been entitled to such additional amounts on presenting the same (or in respect of which the Certificate representing it is presented) for payment on such 30th day; or (d) by a holder which is or was a controlled foreign corporation, personal holding company or passive foreign investment company with respect to the United States or a corporation that accumulates earnings to avoid United States federal income tax; or (e) if such tax is an estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, assessment, or governance charge; or (f) by or on behalf of a holder which is or has been (i) a “10 per cent. shareholder” of the obligor of the Instruments as defined in Section 871(h)(3) of the Code or any successor provisions, (ii) a bank receiving such interest pursuant to a loan agreement entered into in the ordinary course of its trade or business as described in section 881(c)(3)(A) of the Code, or (iii) a controlled foreign corporation within the meaning of section 957 of the Code that is related to the Issuer within the meaning of section 864(d)(4) of the Code; or (g) by or on behalf of a holder who would have been able to avoid such withholding or deduction by satisfying any statutory or procedural requirements (including, without limitation, the provision of information or a United States Internal Revenue Service Form W-8 or Form W-9 (or a successor form)); or (h) in the case of any combination of items (a) to (g) above.

As used in these Conditions, “Relevant Date” in respect of any Instrument 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 13 that, upon further presentation of the Instrument being made in accordance with the Conditions,

A42485973 75 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, all 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 4 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. 7 Prescription Claims against the Issuer for payment in respect of the Instruments shall be prescribed and become void unless made 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. 8 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 U.S.$200,000,000; or (d) Winding-up a resolution is passed, or a final order of a court in the United States of America is made and, where possible, not discharged or stayed within a period of 90 days, that the Issuer be wound up or dissolved; or A42485973 76 (e) Enforcement Proceedings attachment is made of the whole or substantially the whole of the assets or undertakings of the Issuer and such attachment is not released or cancelled within 90 days or an encumbrancer takes possession or an administrative or other receiver or similar officer is appointed of the whole or substantially the whole of the assets or undertaking of the Issuer or an administration or similar order is made in relation to the Issuer and such taking of possession, appointment or order is not released, discharged or cancelled within 90 days; or (f) Insolvency the Issuer ceases to carry on all or substantially all of its business or is unable to pay its debts; or (g) Bankruptcy the Issuer is adjudged bankrupt or insolvent by a court of competent jurisdiction in the United States of America, 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.

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) 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 Instrumentholders or the majority required to pass the Extraordinary Resolution will only be binding if passed at a meeting of the Instrumentholders (or at any adjournment of that meeting) at which a special quorum (as defined in the Trust Deed) is present. A resolution in writing signed by the holders of not less than 95 per cent. in nominal amount of the Instruments will be binding on all Instrumentholders. The Issuer may convene a meeting of the holders of any or all Instruments issued pursuant to the Agency Agreement and not forming a single series with the Instruments to which meeting the provisions referred to above apply as if all such Instruments formed part of the same series, provided that the proposals to be considered at such meeting affect the rights of the holders of the Instruments of each series attending the meeting in identical respects (save insofar as the Conditions applicable to each such series are not identical). 10.2 Modification of the Trust Deed The Trustee may agree, without the consent of the Instrumentholders to (a) any modification of any of the provisions of the Trust Deed that is of a formal, minor or technical nature or is made to correct a manifest error, and (b) any other modification (except as mentioned in the Trust Deed), and any waiver or authorisation of any breach or proposed breach, of any of the provisions of the Trust Deed that is in the opinion of the Trustee not materially prejudicial to the interests of the Instrumentholders. Any such modification, authorisation or waiver shall be binding on the Instrumentholders and, if the Trustee so requires, such modification shall be notified to the Instrumentholders as soon as practicable. In addition, the Trustee shall be obliged to concur with the Issuer in effecting any Benchmark Amendments in the circumstances and as otherwise set out in Condition 3.10 without the consent of the Instrumentholders. Any such modification shall be binding on Instrumentholders and, unless the Trustee otherwise agrees, the Issuer shall cause notice of such modification to be given to the Instrumentholders as soon as practicable thereafter. 10.3 Substitution The Trust Deed contains provisions permitting the Trustee to agree, subject to such amendment of the Trust Deed and such other conditions as the Trustee may require, but without the consent of the Instrumentholders, to the substitution of any other company in A42485973 78 place of the Issuer or of any previous substituted company, as principal debtor under the Trust Deed and the Instruments. In the case of such a substitution the Trustee may agree, without the consent of the Instrumentholders, to a change of the law governing the Instruments and/or the Trust Deed provided that such change would not in the opinion of the Trustee be materially prejudicial to the interests of the Instrumentholders. 10.4 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 and the Trustee shall not be entitled to require, nor shall any Instrumentholder be entitled to claim, from the Issuer any indemnification or payment in respect of any tax consequence of any such exercise upon individual Instrumentholders. 11 Replacement of Certificates If a Certificate 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 the Registrar or such other Paying Agent or Transfer Agent, as the case may be, as may from time to time be designated by the Issuer for the purpose and notice of whose designation is given to Instrumentholders, in each case 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 Certificate is subsequently presented for payment there shall be paid to the Issuer on demand the amount payable by the Issuer in respect of such Certificates and otherwise as the Issuer may require. Mutilated or defaced Certificates must be surrendered before replacements will be issued. 12 Further Issues The Issuer may from time to time without the consent of the Instrumentholders create and issue further instruments having the same terms and conditions as the Instruments and so that such further issue shall be consolidated and form a single series with such Instruments. References in these Conditions to the Instruments include (unless the context requires otherwise) any other instruments issued pursuant to this Condition and forming a single series with the Instruments. Any such further instruments forming a single series with Instruments constituted by the Trust Deed or any deed supplemental to it shall, and any other instruments may (with the consent of the Trustee), be constituted by the Trust Deed. The Trust Deed contains provisions for convening a single meeting of the Instrumentholders and the holders of instruments of other series if the Trustee so decides. 13 Notices Notices to the Instrumentholders shall be mailed to them at their respective addresses shown in the Register and shall be deemed to have been given on the fourth weekday (being a day other than a Saturday or a Sunday) after the date of mailing. 14 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

A42485973 79 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. 15 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. 16 Governing Law and Jurisdiction 16.1 Governing Law The Instruments and any non-contractual obligations arising out of or in connection with the Instruments are governed by, and shall be construed in accordance with, English law. 16.2 Jurisdiction The courts of England have exclusive jurisdiction to settle any dispute (a “Dispute”) arising from or connected with the Instruments. 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. Nothing in this Condition 16 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. 16.3 Process Agent The Issuer has irrevocably appointed National Grid plc at its registered office for the time being, currently at 1-3 Strand, London WC2N 5EH as its agent in England to receive, for it and on its behalf, service of process in any Proceedings in England. Nothing herein or in the Trust Deed shall affect the right to serve process in any other manner permitted by law. 17 Transfers of Instruments (a) Transfers of Instruments One or more Instruments may be transferred upon the surrender (at the specified office of the Registrar or any Transfer Agent) of the Certificate representing such Instruments to be transferred, together with the form of transfer endorsed on such Certificate (or another form of transfer substantially in the same form and containing the same representations and certifications (if any), unless otherwise agreed by the Issuer), duly completed and executed and any other evidence as the Registrar or such Transfer Agent may reasonably require. In the case of a transfer of part only of a holding of Instruments represented by one Certificate, a new Certificate shall be issued to the transferee in respect of the part transferred and a further new Certificate in respect of the balance of the holding not transferred shall be issued to the transferor. All transfers of Instruments and entries on the Register will be made subject to the detailed regulations concerning transfers of Instruments scheduled to the Agency Agreement. The regulations may be changed by the Issuer with the prior written approval of the Registrar and the Trustee. A copy of the current regulations will be made available by the Registrar to any Instrumentholder upon request. (b) Exercise of Options or Partial Redemption In the case of an exercise of an Issuer’s or Instrumentholders’ option in respect of, or a partial redemption of, a holding of Instruments represented by a single Certificate, a new Certificate A42485973 80 shall be issued to the holder to reflect the exercise of such option or in respect of the balance of the holding not redeemed. In the case of a partial exercise of an option resulting in Instruments of the same holding having different terms, separate Certificates shall be issued in respect of those Instruments of that holding that have the same terms. New Certificates shall only be issued against surrender of the existing Certificates to the Registrar or any Transfer Agent. In the case of a transfer of Instruments to a person who is already a holder of Instruments, a new Certificate representing the enlarged holding shall only be issued against surrender of the Certificate representing the existing holding. (c) Delivery of New Certificates Each new Certificate to be issued pursuant to Conditions 17(a) or (b) shall be available for delivery within three business days of receipt of the form of transfer or Exercise Notice and surrender of the Certificate for exchange. Delivery of the new Certificate(s) shall be made at the specified office of the Transfer Agent or of the Registrar (as the case may be) to whom delivery or surrender of such form of transfer, Exercise Notice or Certificate shall have been made or, at the option of the holder making such delivery or surrender as aforesaid and as specified in the relevant form of transfer, Exercise Notice or otherwise in writing, be mailed by uninsured post at the risk of the holder entitled to the new Certificate to such address as may be so specified, unless such holder requests otherwise and pays in advance to the relevant Transfer Agent the costs of such other method of delivery and/or such insurance as it may specify. In this Condition 17(c), “business day” means a day, other than a Saturday or Sunday, on which banks are open for business in the place of the specified office of the relevant Transfer Agent or the Registrar (as the case may be). (d) Transfers Free of Charge Transfers of Certificates on registration, transfer, exercise of an option or partial redemption shall be effected without charge by or on behalf of the Issuer, the Registrar or any Transfer Agent, but upon payment of any tax or other governmental charges that may be imposed in relation to it (or the giving of such indemnity as the Registrar or the relevant Transfer Agent may require). (e) Closed Periods No Instrumentholder may require the transfer of an Instrument to be registered (i) during the period of 15 days ending on the due date for redemption of that Instrument, (ii) during the period of 15 days prior to any date on which Instruments may be called for redemption by the Issuer at its option pursuant to Condition 4.5, (iii) after any such Instrument has been called for redemption or (iv) during the period of seven days ending on (and including) any Record Date.

Convening a meeting 3 The Issuer or the Trustee may at any time convene a meeting. If it receives a written request by Instrumentholders holding at least 10 per cent. in nominal amount of the Instruments of any Series for the time being outstanding and is indemnified to its satisfaction against all costs and expenses, the Trustee shall convene a meeting of the Instrumentholders of that Series.

A copy of the notice shall be given by the party convening the meeting to the other parties. The notice shall specify the day and time of the meeting and manner in which it is to be held, and if a physical meeting or hybrid meeting is to be held, the place of the meeting and, unless the Trustee otherwise agrees, the nature of the resolutions to be proposed and shall explain how Instrumentholders may appoint proxies or representatives, obtain voting certificates and use block voting instructions and the details of the time limits applicable. With respect to a virtual meeting or a hybrid meeting, each notice shall set out further details as required under paragraph 32. Cancellation of meeting 5 A meeting that has been validly convened in accordance with paragraph 3 above, may be cancelled by the person who convened such meeting by giving at least 5 days’ notice (exclusive of the day on which the notice is given or deemed to be given and of the day of the meeting) to the Instrumentholders (with a copy to the Trustee where such meeting was convened by the Issuer or to the Issuer where such meeting was convened by the Trustee). Any meeting cancelled in accordance with this paragraph 5 shall be deemed not to have been convened. Arrangements for voting 6 If a holder of an Instrument wishes to obtain a voting certificate in respect of it for a meeting, the holder must deposit it for that purpose at least 48 hours before the time fixed for the meeting with a Paying Agent or to the order of a Paying Agent with a bank or other depositary nominated by the Paying Agent for the purpose. The Paying Agent shall then issue a voting certificate in respect of it. 7 A voting certificate shall: 7.1 be a document in the English language; 7.2 be dated; 7.3 specify the meeting concerned and the serial numbers of the Instruments deposited; and 7.4 entitle, and state that it entitles, its bearer to attend and vote at that meeting in respect of those Instruments. 8 Once a Paying Agent has issued a voting certificate for a meeting in respect of an Instrument, it shall not release the Instrument until either: 8.1 the meeting has been concluded; or 8.2 the voting certificate has been surrendered to the Paying Agent. 9 9.1 A holder of an Instrument may, by an Instrument in writing in the form available from the specified office of a Transfer Agent in the English language executed by or on behalf of the holder and delivered to the Transfer Agent at least 24 hours before the time fixed for a A42485973 84 meeting, appoint any person (a “proxy”) to act on his behalf in connection with that meeting. A proxy need not be an Instrumentholder. 9.2 A corporation which holds an Instrument may, by delivering to a Transfer Agent at least 24 hours before the time fixed for a meeting a certified copy of a resolution of its directors or other governing body (with, if it is not in English, a certified translation into English), authorise any person to act as its representative (a “representative”) in connection with that meeting. Chair 10 The chair of a meeting shall be such person as the Trustee may nominate in writing, but if no such nomination is made or if the person nominated is not present within 15 minutes after the time fixed for the meeting the Instrumentholders or agents present shall choose one of their number to be chair, failing which the Issuer may appoint a chair. 11 The chair need not be an Instrumentholder or agent. The chair of an adjourned meeting need not be the same person as the chair of the original meeting. Attendance 12 The following may attend and speak at a meeting: 12.1 Instrumentholders and agents; 12.2 the chair; 12.3 the Issuer and the Trustee (through their respective representatives) and their respective financial and legal advisers; and 12.4 the Dealers and their advisers. No one else may attend, participate and/or speak. Quorum and Adjournment 13 No business (except choosing a chair) shall be transacted at a meeting unless a quorum is present at the commencement of business. If a quorum is not present within 15 minutes from the time initially fixed for the meeting, it shall, if convened on the requisition of Instrumentholders or if the Issuer and the Trustee agree, be dissolved. In any other case it shall be adjourned until such date, not less than 14 nor more than 42 days later, and time and place or manner in which it is to be held as the chair may decide. If a quorum is not present within 15 minutes from the time fixed for a meeting so adjourned, the meeting shall be dissolved. 14 Two or more Instrumentholders or agents present at the meeting shall be a quorum: 14.1 in the cases marked “No minimum proportion” in the table below, whatever the proportion of the Instruments which they represent; and 14.2 in any other case, only if they represent the proportion of the Instruments shown by the table below.

A42485973 85 Column 1 Column 2 Column 3 Purpose of meeting Any meeting except one referred to in column 3 Meeting previously adjourned through want of a quorum Required proportion Required proportion To pass a special quorum resolution Two thirds One third To pass any other Extraordinary Resolution A clear majority No minimum proportion Any other purpose 10 per cent. No minimum proportion 15 The chair, may with the consent of (and shall if directed by) a meeting, adjourn the meeting from time to time and from place to place and alternate manner. Only business which could have been transacted at the original meeting may be transacted at a meeting adjourned in accordance with this paragraph or paragraph 13. 16 At least 10 days’ notice (exclusive of the day on which the notice is given or deemed to be given and of the day of the adjourned meeting) of a meeting adjourned through want of a quorum shall be given in the same manner as for an original meeting and that notice shall state the quorum required at the adjourned meeting. However, no notice need otherwise be given of an adjourned meeting. Voting 17 At a meeting which is held only as a physical meeting, each question submitted to such 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 chair, the 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. 18 Unless a poll is demanded a declaration by the chair 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. 19 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 chair 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. 20 A poll demanded on the election of a chair or on a question of adjournment shall be taken at once. 21 On a show of hands every person who is present in person and who produces a Certificate of which he is the registered holder 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 A42485973 86 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. 22 In case of equality of votes the chair 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. 23 At a virtual meeting or a hybrid meeting, a resolution put to the vote of the meeting shall be decided on a poll in accordance with paragraph 34, and any such poll will be deemed to have been validly demanded at the time fixed for holding the meeting to which it relates. Effect and Publication of an Extraordinary Resolution 24 An Extraordinary Resolution shall be binding on all the Instrumentholders, whether or not present at the meeting, 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 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 25 Minutes shall be made of all resolutions and proceedings at every meeting and, if purporting to be signed by the chair of that meeting or of the next succeeding meeting, shall be conclusive evidence of the matters in them. Until the contrary is proved every meeting for which minutes have been so made and signed shall be deemed to have been duly convened and held and all resolutions passed or proceedings transacted at it to have been duly passed and transacted. Written Resolution and Electronic Consent 26 A resolution in writing signed by or on behalf of the holders of not less than 95 per cent. in nominal amount of the Instruments who for the time being are entitled to receive notice of a meeting in accordance with the provisions of this Schedule shall for all purposes be as valid and effectual as an Extraordinary Resolution passed at a meeting of such Instrumentholders duly convened and held in accordance with the provisions of this Schedule. 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 Certificate held on behalf of one or more of Euroclear, Clearstream, Luxembourg or an Alternative Clearing System, then, in respect of any resolution proposed by the Issuer or the Trustee: 27 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-paragraph (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 relevant 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 relevant 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

A42485973 87 Relevant Date): (i) the outstanding nominal amount of the Instruments and (ii) the outstanding nominal 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 relevant 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 relevant Paying Agent in a form satisfactory to it. Any resolution passed in such manner shall be binding on all Instrumentholders, 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). (ii) 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 relevant Paying Agent. Alternatively, the party proposing such resolution (the “Proposer”) may give a further notice to Instrumentholders in accordance with (i) above that the resolution will be proposed again. Such notice must inform Instrumentholders that insufficient consents were received in relation to the original resolution and the information specified in sub- paragraph (i) above. For the purpose of such further notice, references to “Relevant Date” shall be construed accordingly. For the avoidance of doubt, an Electronic Consent may only be used in relation to a resolution proposed by the Issuer or the Trustee which is not then the subject of a meeting that has been validly convened in accordance with paragraph 3 above, unless that meeting is or shall be cancelled or dissolved; and 28 Written Resolution: where Electronic Consent is not being sought, for the purpose of determining whether a Written Resolution has been validly passed, the Issuer and the Trustee shall be entitled to rely on consent or instructions given in writing directly to the Issuer and/or the Trustee, as the case may be, (a) by accountholders in the clearing system(s) with entitlements to such Global Certificates and/or, (b) where the accountholders hold any such entitlement on behalf of another person, on written consent from or written instruction by the person identified by that accountholder as the person for whom such entitlement is held. For the purpose of establishing the entitlement to give any such consent or instruction, the Issuer and the Trustee shall be entitled to rely on any certificate or other document issued by, in the case of (a) above, Euroclear, Clearstream, Luxembourg or any other relevant Alternative Clearing System and, in the case of (b) above, the relevant clearing systems and the accountholder identified by the relevant clearing systems for the purposes of (b) above. A42485973 88 Any resolution passed in such manner shall be binding on all Instrumentholders, even if the relevant consent or instruction proves to be defective. Any such certificate or other document shall, be conclusive and binding for all purposes. Any such certificate or other document may comprise any form of statement or print out of electronic records provided by the relevant clearing systems in accordance with their usual procedures and in which the accountholder of a particular nominal amount of the Instruments is clearly identified together with the amount of such holding. Neither the Issuer, nor the Trustee shall be liable to any person by reason of having accepted as valid or not having rejected any certificate or other document to such effect purporting to be issued by any such person and subsequently found to be forged or not authentic. A Written Resolution or Electronic Consent shall take effect as an Extraordinary Resolution. A Written Resolution and/or Electronic Consent will be binding on all Instrumentholders, whether or not they participated in such Written Resolution and/or Electronic Consent. Trustee’s Power to Prescribe Regulations 29 Subject to all other provisions in this Trust Deed the Trustee may without the consent of the Instrumentholders prescribe or approve such further regulations regarding the holding of meetings and attendance and voting at them as it in its sole discretion determines or as proposed by the Issuer including (without limitation) such requirements as the Trustee thinks reasonable to satisfy itself that the persons who purport to make any requisition in accordance with this Trust Deed are entitled to do so and as to the form of voting certificates or block voting instructions so as to satisfy itself that persons who purport to attend or vote at a meeting are entitled to do so. 30 The holder of a Global Certificate shall (unless such Global Certificate represents only one Instrument) be treated as two persons for the purposes of any quorum requirements of a meeting of Instrumentholders. 31 The above provisions of this Schedule shall have effect subject to the following provisions: 31.1 Meetings of Instrumentholders of separate Series will normally be held separately. However, the Trustee may from time to time determine that meetings of Instrumentholders of separate Series shall be held together. 31.2 A resolution that in the opinion of the Trustee affects one Series alone shall be deemed to have been duly passed if passed at a separate meeting of the Instrumentholders of the Series concerned. 31.3 A resolution that in the opinion of the Trustee affects the Instrumentholders of more than one Series but does not give rise to a conflict of interest between the Instrumentholders of the different Series concerned shall be deemed to have been duly passed if passed at a single meeting of the Instrumentholders of the relevant Series provided that for the purposes of determining the votes an Instrumentholder is entitled to cast pursuant to paragraph 20, each Instrumentholder shall have one vote in respect of each whole Euro 1.00 nominal amount of Instruments held, converted, if such Instruments are not denominated in Euro, in accordance with Clause 8.13 (Currency Conversion). 31.4 A resolution that in the opinion of the Trustee affects the Instrumentholders of more than one Series and gives or may give rise to a conflict of interest between the Instrumentholders of the different Series concerned shall be deemed to have been duly passed only if it shall be duly passed at separate meetings of the Instrumentholders of the relevant Series.
