GUARANTEE

SANTANDER UK PLC

For value received, Santander UK plc, a public limited company incorporated under the laws of England and Wales (the “Guarantor,” which term includes any Person as a successor Guarantor under the Senior Debt Securities Indenture referred to in the Senior Debt Security upon which this Guarantee is endorsed), hereby unconditionally and irrevocably guarantees to the Holder of the Senior Debt Security upon which this Guarantee is endorsed the due and punctual payment of the principal of, any premium and interest on, and any Additional Amounts with respect to such Senior Debt Security, when and as the same shall become due and payable, whether at maturity, by acceleration, redemption, repayment or otherwise, in accordance with the terms of such Senior Debt Security and of the Senior Debt Securities Indenture. In case of the failure of Abbey National Treasury Services plc, a public limited company incorporated in England and Wales (the “Issuer,” which term shall include any successor entity under the Senior Debt Securities Indenture), to punctually pay any such principal, premium, interest or Additional Amounts, the Guarantor hereby agrees to cause any such payment to be made punctually when and as the same shall become due and payable, whether at maturity, upon acceleration, redemption, repayment or otherwise, and as if such payment were made by the Issuer.

The indebtedness evidenced by this Guarantee is ranked equally and pari passu with all other unsecured and unsubordinated indebtedness of the Guarantor.

All payments of principal of and premium, if any, interest and any other amounts on, or in respect of, such Senior Debt Security shall be made by the Guarantor without withholding or deduction at source for, or on account of, any present or future income, stamp and other Taxes now or hereinafter imposed or levied, collected, withheld or assessed by or on behalf of the United Kingdom, or the jurisdiction of residence or incorporation of the Guarantor, or any political subdivision or taxing authority thereof or therein (the “Guarantor Taxing Jurisdiction”), unless such taxes, fees, duties, assessments or governmental charges are required to be withheld or deducted by law. If a withholding or deduction at source is required, the Guarantor shall, subject to the same limitations and exceptions set forth in the Senior Debt Securities Indenture, pay to the Holder of such Senior Debt Security such Additional Amounts as may be necessary so that every net payment of principal, premium, if any, interest or any other amount made to such Holder, after such withholding or deduction, shall not be less than the amount provided for in such Senior Debt Security and the Senior Debt Securities Indenture to be then due and payable.

The Guarantor hereby agrees that its obligations hereunder shall be as principal and not merely as surety, and shall be absolute, irrevocable and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Senior Debt Security or the Senior Debt Securities Indenture, any failure to enforce the provisions of such Senior Debt Security or the Senior Debt Securities Indenture, or any waiver, modification, consent or indulgence granted with respect thereto by the Holder of such Senior Debt Security or the Trustee, the recovery of any judgment against the Issuer or any action to enforce the same, or any other circumstances which may otherwise constitute a legal or equitable discharge of a surety or guarantor. The Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of merger, insolvency or bankruptcy of

A-6

the Issuer, any right to require a proceeding first against the Issuer, protest or notice with respect to any such Senior Debt Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged except by payment in full of the principal of, any premium and interest on, and any Additional Amounts with respect to, the Senior Debt Securities and the complete performance of all other obligations contained in such Senior Debt Security. The Guarantor further agrees, to the fullest extent that it lawfully may do so, that, as between the Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, the maturity of the obligations guaranteed hereby may be accelerated as provided in the Senior Debt Securities Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or prohibition extant under any bankruptcy, insolvency, reorganization or other similar law of any jurisdiction preventing such acceleration in respect of the obligations guaranteed hereby.

This Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment on such Senior Debt Security, in whole or in part, is rescinded or must otherwise be restored to the Issuer or the Guarantor upon the bankruptcy, liquidation or reorganization of the Issuer or otherwise.

The Guarantor shall be subrogated to all rights of the Holder of such Senior Debt Security against the Issuer in respect of any amounts paid to such Holder by the Guarantor pursuant to the provisions of this Guarantee; provided, however, that the Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation until the principal of, any premium and interest on, and any Additional Amounts with respect to, such Senior Debt Security shall have been paid in full.

As a separate and alternative stipulation, the Guarantor unconditionally and irrevocably agrees that any sum expressed to be payable by the Issuer under the Senior Debt Securities Indenture or such Senior Debt Security but which is for any reason (whether or not now known or becoming known to the Issuer, the Guarantor, the Trustee or any Holder of such Senior Debt Security) not recoverable from the Guarantor on the basis of a Guarantee will nevertheless be recoverable from it as if it were the sole principal debtor and will be paid by it to the Trustee on demand. This indemnity constitutes a separate and independent obligation from the other obligations in the Senior Debt Securities Indenture, gives rise to a separate and independent cause of action and will apply irrespective of any indulgence granted by the Trustee or any Holder of such Senior Debt Security.

The Guarantor may, without the consent of the Holders, assume all of the rights and obligations of the Issuer under the Senior Debt Securities Indenture with respect to such Senior Debt Security and under such Senior Debt Security if, after giving effect to such assumption, no Event of Default or event which with the giving of notice or lapse of time, or both, would become an Event of Default, shall have occurred and be continuing. Upon such an assumption, the Guarantor shall execute a supplemental indenture evidencing its assumption of all such rights and obligations of the Issuer and the Issuer shall be released from its liabilities under the Senior Debt Securities Indenture and under such Senior Debt Security as obligor on such Senior Debt Security. The Guarantor shall assume all of the rights and obligations of the Issuer under the Senior Debt Securities Indenture with respect to such Senior Debt Security and under such Senior Debt Security if, upon a default by the Issuer in the due and punctual payment of the principal, premium, if any, or interest on such Senior Debt Security, the Guarantor is prevented by any court order or judicial proceeding from fulfilling its obligations under Section 12.01 of the Senior Debt Securities Indenture with respect to such Senior Debt Security. Such assumption shall result in such Senior Debt Security becoming the direct obligations of the Guarantor and shall be effected without the consent of the Holders of such

A-7

Senior Debt Security. Upon such an assumption, the Guarantor shall execute a supplemental indenture evidencing its assumption of all such rights and obligations of the Issuer, and the Issuer shall be released from its liabilities hereunder and under such Senior Debt Security as obligor on such Senior Debt Security.

No reference herein to such Senior Debt Securities Indenture and no provision of such Senior Debt Securities Indenture shall alter or impair the guarantees of the Guarantor, which are absolute and unconditional, of the due and punctual payment of the principal of, interest on and Additional Amounts payable in respect of the Senior Debt Security upon which this Guarantee is endorsed.

This Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication of such Senior Debt Security shall have been executed by manual or facsimile signature by or on behalf of the Trustee under such Senior Debt Securities Indenture.

All terms used in this Guarantee that are defined in such Senior Debt Securities Indenture shall have the meanings assigned to them in such Senior Debt Securities Indenture.

This Guarantee shall be governed by and construed in accordance with the laws of the State of New York.

[ ]% Notes due [ ]

This Security is one or all of a duly authorized issue of securities of the Issuer (herein called the “Securities”), initially limited in aggregate principal amount to $[ ], issued and to be issued in one or more series under an Indenture, dated as of April 27, 2011 (herein called the “Original Senior Debt Securities Indenture”), among the Issuer, Santander UK plc, as Guarantor (the “Guarantor”) and The Bank of New York Mellon, as trustee (herein called the “Trustee”, which term includes any successor trustee under the Senior Debt Securities Indenture (as defined herein)), as supplemented by the First Supplemental Indenture, dated as of March 13, 2014 (the “First Supplemental Indenture” and, together with the Original Senior Debt Securities Indenture, the “Senior Debt Securities Indenture”), to which Senior Debt Securities Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the Issuer, the Guarantor, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one or all of the series designated as the “[ ]% Notes due [ ].”

As provided in and subject to the provisions of the Senior Debt Securities Indenture, the Issuer and, if applicable, the Guarantor will have the option to redeem the Securities in whole on any Interest Payment Date, at a redemption price equal to 100% of the principal amount, together with accrued but unpaid interest, if any, in respect of the Securities to the date fixed for redemption (or, in the case of Original Issue Discount Securities, the accreted face amount thereof, together with accrued interest, if any), if, at any time, the Issuer (or, if applicable, the Guarantor) shall determine that as a result of a change in or amendment to the laws or regulations of the Taxing Jurisdiction (including any treaty to which such Taxing Jurisdiction is a party), or, based upon a written legal opinion of independent United Kingdom counsel of recognized standing as set forth in the Senior Debt Securities Indenture, any change in the official application or interpretation of such laws or regulations (including a decision of any court or tribunal) which change or amendment becomes effective on or after a date included in the terms of such Securities:

(a) in making payment under the Securities in respect of principal or premium, if any, or interest, if any, it (or the Guarantor, if applicable) has or will or would on the next Interest Payment Date become obligated to pay Additional Amounts;

(b) any payment of Interest on an Interest Payment Date in respect of the Securities has been treated as a “distribution”, or the payment of interest on the next Interest Payment Date in respect of any of the Securities would be treated as a “distribution,” in each case within the meaning of Section 1000 of the Corporation Tax Xxx 0000 of the United Kingdom (or any statutory modification or re-enactment thereof for the time being); or

(c) on an Interest Payment Date the Issuer (or the Guarantor, if applicable) was not entitled, or on the next Interest Payment Date the Issuer (or the Guarantor, if applicable) would not be entitled, to claim a deduction in respect of such payment of interest in computing its United Kingdom taxation liabilities (or the value of such deduction to the Issuer would be materially reduced).

In the event of a redemption as described in the paragraphs above, notice of such redemption to the Holders of the Securities of any series to be redeemed in whole but not in part at the option of the Issuer shall be given by mailing notice of such redemption by first class mail, postage prepaid, at least 30 days and not more than 60 days prior to the date fixed for redemption to such Holders of

A-10

the Securities of such series at their last addresses as they shall appear upon the Security Register of the Issuer.

The Senior Debt Securities Indenture contains provisions for satisfaction and discharge of the Senior Debt Securities Indenture applicable to the Issuer and the Guarantor, in each case, upon compliance by the Issuer and the Guarantor with certain conditions set forth in the Senior Debt Securities Indenture, which provisions apply to this Security.

If an Event of Default with respect to the Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Senior Debt Securities Indenture.

As provided in and subject to the provisions of the Senior Debt Securities Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Senior Debt Securities Indenture or for the appointment of an administrator, receiver or trustee or for any other remedy thereunder, unless such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to such Security specifying such Event of Default and stating that such notice is a “Notice of Default” under the Senior Debt Securities Indenture; the Holders of not less than 25% in aggregate principal amount of such Security shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name, as Trustee hereunder; such Holders have offered to the Trustee reasonable indemnity or security satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity or security has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of such Security. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein.

The Senior Debt Securities Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the Guarantor and the rights of the Holders of the Securities under the Senior Debt Securities Indenture at any time by the Issuer, the Guarantor and the Trustee with the consent of the Holders of not less than a majority in principal amount of the outstanding Securities affected by such amendment. The Senior Debt Securities Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time outstanding, on behalf of the Holders of all Securities, to waive compliance by the Issuer or the Guarantor, or both, with certain provisions of the Senior Debt Securities Indenture and certain past defaults under the Senior Debt Securities Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Senior Debt Securities Indenture and no provision of this Security or of the Senior Debt Securities Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

A-11

The Issuer may, from time to time, without the consent of the Holders of the Securities, issue additional Securities of this series, guaranteed by the Guarantor, having the same ranking and same interest rate, Stated Maturity, redemption terms and other terms, except for the price to the public and issue date and first Interest Payment Date, as this Security; provided, however, that such additional Securities must be either treated as part of the same issue of debt instruments for U.S. federal income tax purposes or be issued with an issue price that is no less than the adjusted issue price of this Security at the time of issuance of such additional Securities for U.S. federal income tax purposes. Any such additional Securities, together with this Security, will constitute a single series of Senior Debt Securities under the Senior Debt Securities Indenture.

As provided in the Senior Debt Securities Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Senior Debt Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place of payment where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Senior Debt Security Registrar duly executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations containing identical terms and provisions, of a like aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and integral multiples of $1,000 in excess thereof. As provided in the Senior Debt Securities Indenture and subject to certain limitations set forth therein, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but, subject to certain exceptions set forth in the Senior Debt Securities Indenture, the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Issuer, the Guarantor, the Trustee and any agent of the Issuer, the Guarantor or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and none of the Issuer, the Guarantor, the Trustee or any such agent shall be affected by notice to the contrary.

The obligations of the Issuer and the Guarantor under the Senior Debt Securities Indenture and this Security and all documents delivered in the name of the Issuer or the Guarantor, as the case may be, in connection herewith and therewith do not and shall not constitute personal obligations of the directors, officers, employees, agents or shareholders of the Issuer or the Guarantor or any of them, and shall not involve any claim against or personal liability on the part of any of them, and all persons including the Trustee shall look solely to the assets of the Issuer and the Guarantor for the payment of any claim thereunder or for the performance thereof and shall not seek recourse against such directors, officers, employees, agents or shareholders of the Issuer or the Guarantor or any of them or any of their personal assets for such satisfaction. The performance of the obligations of the Issuer and the Guarantor under the Senior Debt Securities Indenture and this Security and all documents delivered in the name of the Issuer or the Guarantor, as

A-12

the case may be, in connection therewith shall not be deemed a waiver of any rights or powers of the Issuer or the Guarantor or their respective directors or shareholders under the Issuer’s or the Guarantor’s respective Memorandum and Articles of Association.

By its acquisition of the Securities, each Holder of the Securities: (i) acknowledges and agrees that the exercise of the UK Bail-in Power by the relevant UK resolution authority with respect to the Securities and/or the Guarantees in relation to the Securities shall not give rise to an Event of Default for purposes of Section 315(b) (Notice of Default) and Section 315(c) (Duties of the Trustee in Case of Default) of the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”); (ii) to the extent permitted by the Trust Indenture Act, waives any and all claims against the Trustee for, agrees not to initiate a suit against the Trustee in respect of, and agrees that the Trustee will not be liable for, any action that the Trustee takes, or abstains from taking, in either case in accordance with the exercise of the UK Bail-in Power by the relevant UK resolution authority with respect to the Securities; (iii) acknowledges and agrees that, upon the exercise of any UK Bail-in Power by the relevant UK resolution authority, (a) the Trustee shall not be required to take any further directions from Holders under Section 5.12 of the Original Senior Debt Securities Indenture and (b) the Senior Debt Securities Indenture shall not impose any duties upon the Trustee whatsoever with respect to the exercise of any UK Bail-in Power by the relevant UK resolution authority; (iv) shall be deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the exercise of any UK Bail-in Power with respect to the Securities as it may be imposed, without any further action or direction on the part of such Holder or beneficial owner of the Securities; (v) acknowledges and agrees that no repayment of the principal amount of the Securities or payment of interest on the Securities will become due and payable after the exercise of any UK Bail-in Power by the relevant UK resolution authority unless, at the time that such repayment or payment, respectively, is scheduled to become due, such repayment or payment would be permitted to be made by the Issuer after the exercise of such UK Bail-in Power; and (vi) acknowledges and agrees to be bound by and consents to the exercise of any UK Bail-in Power as it may be imposed without any prior notice by the relevant UK resolution authority of its decision to exercise such power with respect to the Securities. Notwithstanding clause (iii), if, following the completion of the exercise of the UK Bail-in Power by the relevant UK resolution authority, the Securities remain outstanding (for example, if the exercise of the UK Bail-in Power results in only a partial write-down of the principal of the Securities), then the Trustee’s duties under the Senior Debt Securities Indenture shall remain applicable with respect to the Securities following such completion to the extent the Issuer, the Guarantor and the Trustee shall agree pursuant to a supplemental indenture or an amendment to the Senior Debt Securities Indenture; provided, however, that notwithstanding the exercise of the UK Bail-in Power by the relevant UK authority, there will at all times be a trustee hereunder pursuant to, and in accordance with, Section 6.09 of the Original Senior Debt Securities Indenture and the resignation and/or removal of the Trustee and the appointment of a successor trustee shall continue to be governed by Sections 6.10 and 6.11 of the Original Senior Debt Securities Indenture, respectively, including to the extent no additional supplemental indenture or amendment to the Senior Debt Securities Indenture is agreed upon pursuant to the Senior Debt Securities Indenture.

Upon the exercise of the UK Bail-in Power by the relevant UK resolution authority with respect to the Securities, the Issuer shall provide a written notice to DTC as soon as practicable regarding such exercise of the UK Bail-in Power for purposes of notifying Holders of such occurrence. The Issuer shall also deliver a copy of such notice to the Trustee for information purposes.

“UK Bail-in Power” means any statutory power to effect a cancellation, write-down, reduction, modification and/or conversion of a liability existing from time to time under any laws, regulations, rules or requirements relating to the resolution of banks, banking group companies, credit institutions, investment firms and/or their parent undertakings incorporated in the United Kingdom in effect and applicable to the Issuer, the Guarantor or any subsidiary undertakings of the Guarantor, including but not limited to the UK Banking Xxx 0000, as the same may be amended from time to time (whether pursuant to the UK Financial Services (Banking Xxxxxx) Xxx 0000 or otherwise), and any laws, regulations, rules or requirements which are implemented, adopted or enacted within the context of a European Union directive or regulation of the European Parliament and of the EU Council establishing a framework for the recovery and resolution of credit institutions, investment firms and/or their parent undertakings, pursuant to which liabilities of a bank, banking group company, a credit institution, investment firm, its parent undertaking or any of its affiliates can be cancelled, written down, reduced, modified and/or converted into shares or other securities or obligations of the Issuer or any other person.

Floating Rate Notes due [ ]

The calculation agent, who shall be the Trustee, or its successor appointed by the Issuer, will determine the initial interest rate by reference to LIBOR on the second London Banking Day preceding the issue date and the interest rate for each succeeding Interest Reset Date by reference to LIBOR on the second London Banking Day preceding the applicable Interest Reset Date (each, an “Interest Determination Date”). Promptly upon such determination, the calculation agent will notify the Issuer and the Trustee (if the calculation agent is not the Trustee) of the new interest rate. Upon the request of a holder of this Security, the calculation agent will provide the interest rate then in effect and, if determined, the interest rate that will become effective on the next Interest Reset Date.

“BBA” means the British Bankers’ Association.

A “London Banking Day” means any day on which dealings in U.S. Dollars are transacted in the London interbank market.

“LIBOR” means, as of any Interest Determination Date:

(2) if no such rate is so published, then the rate for such Interest Determination Date shall be the arithmetic mean (rounded to five decimal places, with 0.000005 being rounded upwards) of the rates for three-month U.S. Dollar deposits quoted by the Reference Banks to the Trustee as of 11:00 a.m., London time, on such Interest Determination Date (it being

B-10

understood that at least two such quotes must have been so provided to the Trustee); or

(3) if LIBOR cannot be determined on such Interest Determination Date using the foregoing methods, then LIBOR on such Interest Determination Date shall be LIBOR in effect as determined using the foregoing methods for the first calendar day preceding such Interest Determination Date on which LIBOR can be so determined.

“Reference Banks” means each of four major reference banks in the London interbank market, as selected by the Issuer or the Guarantor.

The amount of interest accrued on this Security to each Interest Payment Date will be calculated by multiplying the principal amount of this Security by an accrued interest factor. The accrued interest factor will be equal to the sum of the interest factors calculated for each day in the period for which interest is being paid. The interest factor for each day is equal to the interest rate applicable to that day divided by 360. The interest rate in effect on any Interest Reset Date will be the applicable rate as reset on that date. The interest rate applicable to any other day is the interest rate from the immediately preceding Interest Reset Date, or, if none, the initial interest rate.

The performance of the obligations of the Issuer and the Guarantor under the Senior Debt Securities Indenture and this Security and all documents delivered in the name of the Issuer or the Guarantor, as the case may be, in connection therewith shall not be deemed a waiver of any rights or powers of the Issuer or the Guarantor or their respective directors or shareholders under the Issuer’s or the Guarantor’s respective Memorandum and Articles of Association.

B-14

In addition to the right to enter into supplemental indentures pursuant to Sections 9.01 and 9.02 of the Original Senior Debt Securities Indenture, the Issuer, the Guarantor and the Trustee may enter into one or more indentures supplemental to the Senior Debt Securities Indenture to modify and amend the terms of the Senior Debt Securities Indenture or the Securities, without the further consent of any Holders, to the extent necessary to give effect to the exercise by the relevant UK resolution authority of the UK Bail-in Power.

“relevant UK resolution authority” means any authority with the ability to exercise a UK Bail-in Power.

All terms used in this Security that are defined in the Senior Debt Securities Indenture shall have the meanings assigned to them in the Senior Debt Securities Indenture.
