Certain terms, unless otherwise defined here, have the meaning given to them in the relevant indenture.

General

Our debt securities registered pursuant to Section 12(b) of the Act comprise senior fixed rate notes issued under the 2015 Senior Indenture (as defined below) (“the “Fixed Rate Notes”) senior fixed rate/floating rate notes issued under the 2017 Senior Indenture (as defined below) (the “Fixed Rate/Floating Rate Notes”) and the 1.532% Fixed Rate Resetting Notes due 2026 issued under the 2017 Senior Indenture (together with the Fixed Rate Notes and the Fixed Rate/Floating Rate Notes, the “debt securities”).

Each series of Fixed Rate Notes was issued under an indenture dated as of October 9, 2015, entered into between us and the Law Debenture Trust Company of New York as trustee (the “2015 Senior Indenture”). Each Series of Fixed Rate/Floating Rate Notes and the 1.532% Fixed Rate Resetting Notes due 2026 were issued under an amended and restated indenture dated as of April 18, 2017, entered into between us and Wells Fargo Bank, National Association, as trustee (the “2017 Senior Indenture”). The 2015 Senior Indenture and the 2017 Senior Indenture, and any respective supplements thereto, are referred to herein individually as an “indenture” and collectively as the “indentures.” The terms of the debt securities include those stated in the relevant indenture and any supplements thereto, and those terms made part of the relevant indenture by reference to the U.S. Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). Each series of debt securities listed in the table above was issued pursuant to an effective registration statement and a related prospectus and prospectus supplement setting forth the terms of the relevant series of debt securities.

The indentures do not limit the amount of debt securities that we may issue. We may issue debt securities in one or more series and we may, without the consent of the holders of the debt securities of any series, issue additional debt securities, having the same ranking and same interest rate, maturity date, redemption terms and other terms as the debt securities. In respect of the 3.125% Notes due 2021 and the 2.875% Notes due 2021, we may issue additional debt securities of the same series, provided however that such additional debt securities must be fungible with the applicable series of debt securities for U.S. federal income tax purposes. In respect of the 3.751% Notes due 2023, we may issue additional debt securities of the same series, provided however that such additional debt 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 the debt securities at the time of the issuance of such debt securities for U.S. federal income tax purposes. In respect of the 3.823% Fixed Rate/Floating Rate Notes due 2028, the 3.373% Fixed Rate/Floating Rate Notes due 2024, the 4.796% Fixed Rate/Floating Rate Notes due 2024 and the 1.532% Fixed Rate Resetting Notes due 2026, we may issue additional debt securities of the same series, provided however that such additional debt securities shall be issued under a separate CUSIP, Common Code and/or ISIN number unless the additional debt securities are issued pursuant to a “qualified reopening” of the debt securities offered by the relevant prospectus supplement, are otherwise treated as part of the same “issue” of debt instruments as the debt securities offered by the relevant prospectus supplement, or the debt securities offered in the relevant prospectus supplement and the additional debt securities are issued with no more than a de minimis amount of original issue, discount, in each case for U.S. federal income tax purposes.

The debt securities are not secured by any assets or property of Santander UK Group Holdings plc or any of its subsidiaries or affiliates (including Santander UK plc).

Holders of the debt securities have no voting rights except those described under the heading “Modification and Waiver” below.

The debt securities are not subject to any sinking fund.

Interest

The relevant interest rates and interest payment dates of the debt securities are set out in the table above.

Interest on the Fixed Rate Notes, the Fixed Rate/Floating Rate Notes (during the fixed rate period) and the 1.532% Fixed Rate Resetting Notes due 2026 is computed on the basis of a 360-day year of twelve 30-day months, and, in the case of the floating rate interest period of the Fixed Rate/Floating Rate Notes, on the basis of the actual number of days elapsed in each floating rate interest period and a 360-day year.

Payments

If any scheduled fixed rate interest payment date for the Fixed Rate Notes and the 1.532% Fixed Rate Resetting Notes due 2026, and during the fixed rate period of the Fixed Rate/Floating Rate Notes would fall on a day that is not a Business Day (as defined below), then the fixed rate interest payment date will be postponed to the next succeeding business day, but no additional interest shall accrue and be paid unless we fail to make payment on such next succeeding business day. If any scheduled floating rate interest payment date, other than the maturity date, during the floating rate period of the Fixed Rate/Floating Rate Notes, would fall on a day that is not a Business Day, such floating rate interest payment date will be postponed to the next succeeding Business Day and interest thereon will continue to accrue to but excluding such succeeding Business Day, except that if that Business Day falls in the next succeeding calendar month, the floating rate interest payment date will be the immediately preceding Business Day and interest shall accrue to but excluding such preceding Business Day. “Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions in the City of New York or London, England are authorized or required by law, regulation or executive order to close.

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System.

Floating Rate Interest – LIBOR

The Fixed Rate/Floating Rate Notes will bear interest during the floating rate period at the then-applicable U.S. dollar three-month London Interbank Offered Rate (“LIBOR”), reset quarterly on the applicable interest payment date (the “interest reset date”), plus a certain percentage per year as set forth in the table above.

Wells Fargo Bank, National Association, or its successor appointed by us, as calculation agent, determines the floating interest rate for each floating rate interest period by reference to the then-applicable LIBOR on the applicable interest determination date. The interest determination date for each floating rate interest period is the second London banking day (being any day on which dealings in U.S. dollars are transacted in the London interbank market) preceding the applicable interest reset date.

Calculation of LIBOR

3.823% Fixed Rate/Floating Rate Notes due 2028 and 3.373% Fixed Rate/Floating Rate Notes due 2024

Under the terms of the 3.823% Fixed Rate/Floating Rate Notes due 2028 and the 3.373% Fixed Rate/Floating Rate Notes due 2024, LIBOR means, as of any interest determination date:

(1)    the offered quotation to leading banks in the London interbank market for three-month U.S. dollar deposits (i) as defined by (A) the ICE Benchmark Administration (“IBAM”), (B) its successor in such capacity, or (C) such other person assuming the responsibility of IBAM or its successor in calculating the London Inter-Bank Offered Rate in the event IBAM or its successor no longer do so, and (ii) as calculated by their appointed calculation agent and published, as such rate appears on either the Reuters Monitor Money Rates Service page LIBOR01 (or a successor page on such service) or, if such rate is not available, on such other information system that provides such information, in each case as of 11:00 a.m., London time, on such interest determination date; and

(2)    if no such rate is so published on such interest determination date due to a temporary disruption in service or the market, 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 to the calculation agent by each of four major reference banks in the London interbank market (which may include affiliates of the underwriters of the applicable series of debt securities), as selected by the us, as of 11:00 a.m., London time, on such interest determination date (it being understood that at least two such quotes must have been so provided to the calculation agent); or

(3)    if LIBOR cannot be determined under sub-paragraph (1) hereof due to the London Inter-Bank Offered Rate having been permanently discontinued or it being unlawful for either the calculation agent or the issuer to determine or use the London Inter-Bank Offered Rate, then the rate of interest for such interest determination date will be the rate determined for or otherwise applicable during the last preceding interest period (without any margin, if such preceding interest period falls within the Fixed Rate Period).

The amount of interest accrued on the applicable series of debt securities to each floating rate period interest payment date will be calculated by multiplying the principal amount of such debt securities 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 applicable fixed interest rate of the debt securities.

4.796% Fixed Rate/Floating Rate Notes due 2024

Under the terms of the 4.796% Fixed Rate/Floating Rate Notes due 2024, LIBOR means, as of any interest determination date:

(1)    the offered quotation to leading banks in the London interbank market for three-month U.S. dollar deposits (i) as defined by (A) the ICE Benchmark Administration ("IBAM"), (B) its successor in such capacity, or (C) such other person assuming the responsibility of IBAM or its successor in calculating the London Inter-Bank Offered Rate in the event IBAM or its successor no longer do so, and (ii) as calculated by their appointed calculation agent and published, as such rate appears on either the Reuters Monitor Money Rates Service page LIBOR01 (or a successor page on such service) or, if such rate is not available, on such other information system that provides such information, in each case as of 11:00 a.m., London time, on such interest determination date;

(2)    if no such rate is so published on such interest determination date due to a temporary disruption in service or the market, 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 to the calculation agent by each of four major reference banks in the London interbank market (which may include affiliates of the underwriters of such debt securities), as selected by us, as of 11:00 a.m., London time, on such interest determination date:

–if at least two such rates are so provided, LIBOR on the interest determination date will be the arithmetic mean of such rates; or

–if fewer than two such rates are so provided, LIBOR on the interest determination date will be LIBOR as determined for or otherwise applicable during the last preceding interest period.

(3)    Notwithstanding clause (2) above, with respect to an interest determination date on which no rate appears on the relevant screen page, if we (in consultation with the calculation agent) determine that LIBOR has ceased to be published on the relevant screen page as a result of LIBOR ceasing to be calculated or administered for publication thereon or that it is unlawful for either the calculation agent or us to determine or use the London Inter-Bank Offered Rate, we will use reasonable efforts to appoint an Independent Adviser to determine (in consultation with us) the Alternative Base Rate and the Alternative Screen Page by no later than five business days prior to the interest determination date relating to the next succeeding interest period (the “interest determination cut-off date”) for the purpose of determining the rate of interest applicable to the floating rate notes for all future interest periods (subject to the subsequent operation of this paragraph (3)). If we are unable to appoint an Independent Adviser, or if the Independent Adviser fails to determine the Alternative Base Rate and the Alternative Screen Page prior to the interest determination cut-off date, we will determine the Alternative Base Rate and the Alternative Screen Page for such Interest Period; provided that if we do not determine the Alternative Base Rate and the Alternative Screen Page prior to the interest determination date for such interest period, the interest rate for such interest period will be equal to the interest rate in effect for the immediately preceding interest period.

“Adjustment Spread” means a spread (which may be positive or negative) or formula or methodology for calculating a spread, which the Independent Adviser (in consultation with us) or, only if the Independent Adviser fails to make any such determination, we, determine is

required to be applied to the Alternative Base Rate, as a result of the replacement of LIBOR with the Alternative Base Rate and is the spread, formula or methodology which:

(A) has been formally recommended, or formally provided as an option for parties to elect to adopt, by the Bank of England (or any committee thereof or other body appointed or endorsed thereby for such purpose) in relation to the replacement of LIBOR with the Alternative Base Rate;

(B) the Independent Adviser (in consultation with us) or, failing which, we, determine is recognized or acknowledged as being in customary market usage for the purposes of determining floating rates of interest in respect of securities denominated in U.S. dollars, where such rate has been replaced by the Alternative Base Rate; or

(C) if no such customary market usage is recognized or acknowledged, the Independent Adviser in its discretion (in consultation with us), or, failing which, we in our discretion, determine (acting in good faith) to be appropriate;

“Alternative Base Rate” means the rate that the Independent Adviser or, failing which, we determine has replaced LIBOR in customary market usage for determining floating interest rates in respect of bonds denominated in U.S. dollars or, if the Independent Adviser or, failing which, we (in consultation with the calculation agent and acting in good faith and a commercially reasonable manner) determine that there is no such rate, such other rate as the Independent Adviser or, failing which, we (in consultation with the calculation agent and acting in good faith and a commercially reasonable manner) determine in its or our sole discretion is most comparable to LIBOR. If the Alternative Base Rate is determined, such Alternative Base Rate will be the Alternative Base Rate for the remaining interest periods (subject to the subsequent operation of paragraph (3) above).

“Alternative Screen Page” means the alternative screen page, information service or source on which the Alternative Base Rate appears (or such other screen page, information service or source as may replace the alternative screen page, information service or source, in each case, as may be nominated by the person providing or sponsoring the information appearing on such screen page, information service or source for purposes of displaying comparable rates).

“Independent Adviser” means an independent financial institution of international repute or other independent adviser experienced in the international capital markets, in each case appointed by us at our own expense.

If the Independent Adviser (in consultation with us) or, only if the Independent Adviser fails to make any such determination, we, determine that an Adjustment Spread is required to be applied to the Alternative Base Rate and determine the quantum of, or a formula or methodology for determining, such Adjustment Spread, then such Adjustment Spread shall be applied to the Alternative Base Rate. If the Independent Adviser is, or, failing which, we are, as the case may be, unable to determine the quantum of, or a formula or methodology for determining, such Adjustment Spread, then such Alternative Base Rate will apply without an Adjustment Spread.

If the Independent Adviser or, failing which, we, determine the Alternative Base Rate or any Adjustment Spread, the Independent Adviser or, failing which, we, may also, following consultation with the calculation agent, make changes to the Alternative Base Rate or the Adjustment Spread, as well as the day count fraction, the business day convention, the definition of business day, the remaining interest determination dates and any method for obtaining the substitute or successor base rate if the Alternative Base Rate or the Alternative Screen Page is unavailable on the relevant interest determination date or otherwise, in each case in order to follow market practice, as well as any other changes that we, following consultation with the Independent Adviser (if appointed), determine in good faith are reasonably necessary to ensure the proper operation of the Alternative Base Rate, as well as the comparability of the interest rate determined by reference to the Alternative Base Rate to the interest rate determined by reference to LIBOR (the "Floating Rate Calculation Changes"). Any Floating Rate Calculation Changes will apply to the floating rate notes for all future interest rate periods (subject to the subsequent operation of paragraph (3) above).

We will promptly give notice of the determination of the Alternative Base Rate, any Adjustment Spread, the Alternative Screen Page and any Floating Rate Calculation Changes to the trustee, the paying agent, the calculation agent and the holders of debt securities; provided that failure to provide such notice will have no impact on the effectiveness of, or otherwise invalidate, any such determination.

The amount of interest accrued on the debt securities to (but excluding) each floating rate period interest payment date will be calculated by multiplying the principal amount of the notes 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 fixed interest rate of the debt securities.

By its acquisition of the applicable series of debt securities, each holder of such debt securities (including each holder of a beneficial interest in the debt securities) (i) will acknowledge, accept, consent and agree to be bound by the Independent Adviser's or our determination of the Alternative Base Rate, the Alternative Screen Page, any Adjustment Spread and any Floating Rate Calculation Changes, including as may occur without any prior notice from us and without the need for us to obtain any further consent from such holder of such debt securities, (ii) will waive any and all claims, in law and/or in equity, against the trustee, the paying agent and the calculation agent for, agree not to initiate a suit against the trustee, the paying agent and the calculation agent in respect of, and agree that none of the trustee, the paying agent or the calculation agent will be liable for, the determination of or the failure to determine any Alternative Base Rate, the Alternative Screen Page, any Adjustment Spread or any Floating Rate Calculation Changes and any losses suffered in connection therewith and (iii) will agree that none of the trustee, the paying agent or the calculation agent will have any obligation to determine any Alternative Base Rate, the Alternative Screen Page, any Adjustment Spread or any Floating Rate Calculation Changes (including any adjustments thereto), including in the event of any failure by us to determine any Alternative Base Rate, the Alternative Screen Page, any Adjustment Spread and any Floating Rate Calculation Changes.

1.532% Fixed Rate Resetting Notes due 2026

Under the terms of the 1.532% Fixed Rate Resetting Notes due 2026, from (and including) the issue date to (but excluding) the Reset Date, the notes will bear interest at a rate of 1.532% per year (the “Initial Interest Rate”). From (and including) the Reset Date to (but excluding) the Maturity Date (the "Reset Period"), the applicable per annum interest rate (the "Subsequent Interest Rate") will be equal to the sum, as determined by the calculation agent, of the then-prevailing U.S. Treasury Rate (as defined below, such term subject to the provisions described below) on the Reset Determination Date, plus 1.250%.

"U.S. Treasury Rate" means, with respect to the Reset Period, the rate per annum equal to: (1) the yield, under the heading which represents the average for the week immediately prior to the Reset Determination Date, appearing in the most recently published statistical release designated "H.15", or any successor publication that is published by the Board of Governors of the Federal Reserve System that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity, under the caption "Treasury Constant Maturities", for the maturity of one year; or (2) if such release (or any successor release) is not published during the week immediately prior to the Reset Determination Date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue (as defined below), calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for the Reset Determination Date.

The U.S. Treasury Rate will be determined by the calculation agent. If the U.S. Treasury Rate cannot be determined, for whatever reason, as described under (1) or (2) above, "U.S. Treasury Rate" means the rate in percentage per annum as notified by the calculation agent to the issuer equal to the yield on U.S. Treasury securities having a maturity of one year as set forth in the most recently published statistical release designated "H.15" under the caption "Treasury Constant Maturities" (or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption "Treasury Constant Maturities" for the maturity of one year) at 5:00 p.m. (New York City time) on the last available date preceding the Reset Determination Date on which such rate was set forth in such release (or any successor release).

"Comparable Treasury Issue" means, with respect to the Reset Period, the U.S. Treasury security or U.S. Treasury securities selected by the issuer with a maturity date on or about the last day of the Reset Period and that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities denominated in U.S. dollars and having a maturity of one year.

"Comparable Treasury Price" means, with respect to the Reset Determination Date, (i) if five Reference Treasury Dealer Quotations (as defined below) for the Reset Determination Date are received, the arithmetic average of such Reference Treasury Dealer Quotations, after excluding the highest and lowest such Reference Treasury Dealer Quotations, (ii) if fewer than five but more than one Reference Treasury Dealer Quotations for the Reset Determination Date are received, the arithmetic average of all such

Reference Treasury Dealer Quotations, or (iii) if only one Reference Treasury Dealer Quotation for the Reset Determination Date is received, such Reference Treasury Dealer Quotation.

"Reference Treasury Dealer" means, with respect to the Reset Determination Date, each of up to five banks selected by the issuer, or the affiliates of such banks, which are (i) primary U.S. Treasury securities dealers, and their respective successors, or (ii) market makers in pricing corporate bond issues denominated in U.S dollars.

"Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and the Reset Determination Date, the arithmetic average, as determined by the Calculation Agent, of the bid and offered prices (such prices being obtained by the issuer and furnished to the Calculation Agent) for the applicable Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, at 11:00 a.m. (New York City time) on the Reset Determination Date.

The calculation agent for the 1.532% Fixed Rate Resetting Notes due 2026 will be an independent financial institution of international standing that is not one of our affiliates, as appointed by us at our expense, or, if it is not reasonably practicable to appoint such a party, us or one of our affiliates, which we refer to as the calculation agent. The calculation agent will determine the Subsequent Interest Rate for the notes by reference to the then-prevailing U.S. Treasury Rate, on the Reset Determination Date. Promptly upon such determination, the calculation agent will notify the issuer and the trustee of the Subsequent Interest Rate.

Ranking

Our debt securities constitute our direct, unconditional, unsecured and unsubordinated obligations ranking pari passu without preference among themselves, with all our other outstanding unsecured and unsubordinated obligations, present and future, except such obligations as are preferred by operation of law.

No Set-off

In respect of the 3.125% Notes due 2021, by accepting each debt security, each holder will be deemed to have waived any right of set-off, counterclaim or combination of accounts with respect to the debt securities or the applicable indenture that they might otherwise have against us, whether before or during our winding up.

In respect of the 2.875% Notes due 2021, the 3.571% Notes due 2023, the 1.532% Fixed Rate Resetting Notes due 2026, subject to applicable law, no holder of debt securities may exercise, claim or plead any right of set-off, compensation or retention in respect of any amount owed to it by us arising under or in connection with the debt securities or the relevant indenture, and each holder of the debt securities shall, by virtue of being the holder of the debt securities, be deemed to have waived all such rights of set-off, compensation or retention. Notwithstanding the preceding sentence, if any of the amounts owing to any holder of the applicable series of debt securities by us is discharged by set-off, such holder shall, unless such payment is prohibited by law, immediately pay us an amount equal to the amount of such discharge or, in the event of our winding-up or administration, the liquidator or administrator, as appropriate, and, until such time as payment is made, shall hold an amount equal to such amount in trust for us, or the liquidator or administrator, as appropriate and accordingly any such discharge shall be deemed not to have taken place.

Redemption

Tax Redemption

Payment of Additional Amounts

3.125% Fixed Rate Notes due 2021

Under the terms of the 3.125% Fixed Rate Notes due 2021, amounts to be paid on the applicable series of debt securities will be made without deduction or withholding for, or on account of, any and all present and future income, stamp and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of the country in which we are organized or any political subdivision or authority thereof or therein having the power to tax (the “taxing jurisdiction”), unless such deduction or withholding is required by fiscal or other laws, regulations and directives. If at any time a taxing jurisdiction requires us to make such deduction or withholding, we will pay additional amounts with respect to the principal of, interest and any other payments on, the debt securities (“Additional Amounts”) that are necessary in order that the net amounts paid to the holders of those debt securities, after the deduction or withholding, shall equal the amounts which would have been payable on that series of debt securities if the deduction or withholding had not been required. However, this will not apply to any such amount that would not have been payable or due but for the fact that:

–the holder or the beneficial owner of the debt securities is a domiciliary, national or resident of, or engaging in business or maintaining a permanent establishment or physically present in, a taxing jurisdiction or otherwise having some connection with the taxing jurisdiction other than the holding or ownership of a debt security, or the collection of any payment of, or in respect of, principal of, or any interest or other payment on, any debt security of the relevant series;

–except in the case of a winding up in the UK, the relevant debt security is presented (where presentation is required) for payment in the UK;

–the relevant debt security is presented (where presentation is required) for payment more than 30 days after the date payment became due or was provided for, whichever is later, except to the extent that the holder would have been entitled to the Additional Amounts on presenting the debt security for payment at the close of that 30 day period;

–the holder or the beneficial owner of the relevant debt security or the beneficial owner of any payment of or in respect of principal of, or any interest or other payment on, the debt security failed to comply with a request by us or our liquidator or other authorized person addressed to the holder (x) to provide information concerning the nationality, residence or identity of the holder or the beneficial owner or (y) to make any declaration or other similar claim to satisfy any information requirement, which, in the case of (x) or (y) is required or imposed by a statute, treaty, regulation or administrative practice of a taxing jurisdiction as a precondition to exemption from all or part of the tax, assessment or other governmental charge;

–the withholding or deduction is imposed on a payment to or for the benefit of an individual and is required to be made pursuant to European Council Directive 2003/48/EC, as amended, or any law implementing or complying with, or introduced in order to conform to, such directive;

–the relevant debt security is presented (where presentation is required) for payment by or on behalf of a holder who would have been able to avoid such withholding or deduction by presenting (where presentation is required) the relevant debt security to another paying agent in a member state of the European Union; or

nor shall Additional Amounts be paid with respect to the principal of, premium, if any, and any interest on, the debt securities to any holder who is a fiduciary or partnership or settlor with respect to such fiduciary or a member of such partnership other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of any taxing jurisdiction to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts, had it been the holder. For the avoidance of doubt, all payments in respect of the applicable debt securities will be made subject to any withholding or deduction required pursuant to any fiscal or other laws, regulations and directives, including FATCA, and we shall not be required to pay Additional Amounts with respect to the principal of, interest and any other payments on, the applicable debt securities on account of any such deduction or withholding required pursuant to FATCA.

2.875% Notes due 2021, 3.571% Notes due 2023, Fixed Rate/Floating Rate Notes and 1.532% Fixed Rate Resetting Notes due 2026

–except in the case of a winding up in the UK, the relevant debt security is presented (where presentation is required) for payment in the UK;

–the holder or the beneficial owner of the relevant debt security or the beneficial owner of any payment of or in respect of principal of, or any interest or other payment on, the debt security failed to comply with a request by us or the liquidator or other authorized person addressed to the holder (x) to provide information concerning the nationality, residence or identity of the holder or the beneficial owner or (y) to make any declaration or other similar claim to satisfy any information requirement, which, in the case of (x) or (y) is required or imposed by a statute, treaty, regulation or administrative practice of a taxing jurisdiction as a precondition to exemption from all or part of the tax, assessment or other governmental charge; or

–any combination of the above items;

nor shall Additional Amounts be paid with respect to the principal of, premium, if any, and any interest on, the debt securities to any holder who is a fiduciary or partnership or settlor with respect to such fiduciary or a member of such partnership other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of any taxing jurisdiction to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts, had it been the holder. For the avoidance of doubt, all payments in respect of the debt securities will be made subject to any withholding or deduction required pursuant to any fiscal or other laws, regulations and directives, including FATCA, and we shall not be required to pay Additional Amounts with respect to the principal of, interest and any other payments on, the debt securities on account of any such deduction or withholding required pursuant to FATCA.

Events of Default, Defaults and Events of Default and Remedies

Events of Default

With respect to the Fixed Rate Notes for which “Events of Default” is indicated in the table above, each of the following is an “Event of Default”:

–Failure to pay any principal or interest on any debt securities of that series within 14 days from the due date for payment and the principal or interest has not been duly paid within a further 14 days following written notice from the trustee or from holders of 25% in outstanding principal amount of the debt securities of that series to us requiring the payment to be made. It shall not, however, be an Event of Default if during the 14 days after the notice, we satisfy the trustee that such sums were not paid in order to comply with a law regulation or order of any court of competent jurisdiction. Where there is doubt as to the validity or applicability of any such law, regulation or order, it shall not be an Event of Default if we act on the advice given to us during the 14 day period by independent legal advisers approved by the trustee; or

–Breach of any covenant or warranty of the relevant indenture (other than as stated above with respect to payments when due) and that breach has not been remedied or waived within 60 days of receipt of a written notice from holders of at least 25% in outstanding principal amount of the debt securities of that series requiring the breach to be remedied; or

–Either a court of competent jurisdiction issues an order which is not successfully appealed within 30 days, or an effective shareholders’ resolution is validly adopted, for our winding-up (other than under or in connection with a scheme of reconstruction, merger or amalgamation not involving bankruptcy or insolvency).

If an Event of Default occurs and is continuing, the trustee or the holders of at least 25% in outstanding principal amount of the debt securities of the applicable series may at their discretion declare the debt securities of that series to be due and repayable immediately (and the debt securities of that series shall thereby become due and repayable) at their outstanding principal amount (or at such other repayment amount as may be specified in or determined in accordance with the relevant prospectus supplement) together with accrued interest, if any, as provided in the prospectus supplement. The trustee may at its discretion and without further notice institute such proceedings as it may think suitable, against us to enforce payment. Subject to the indenture provisions for the indemnification of or provision of security to the trustee, the holder(s) of a majority in aggregate principal amount of the outstanding debt securities of any series shall have the right to direct any trust or power conferred on the trustee with respect to the series. However, this direction must not be in conflict with any rule of law or the indenture and must not be unjustly prejudicial to the holder(s) of any debt securities of that series not taking part in the direction, as determined by the trustee. The trustee may also take any other action, consistent with the direction, that it deems proper.

Defaults and Events of Default

With respect to the Fixed Rate/Floating Rate Notes and the 1.532% Fixed Rate Resetting Notes due 2026 for which “Defaults and Events of Default” is indicated in the table above, subject to certain exceptions, it will be an “Event of Default” only if an order is made or entered by an English court which is not successfully appealed within 30 days after the date such order was made or entered for our winding up or an effective resolution is validly adopted by our shareholders for our winding up (in either case, other than in connection with a scheme of amalgamation or reconstruction not involving bankruptcy or insolvency). If an event of default occurs and is continuing with respect to a series of debt securities (except in any such case for a solvent winding-up solely for the purpose of a merger, reconstruction or amalgamation of us, the terms of which reorganization, reconstruction or amalgamation (i) have previously been approved in writing by a majority of holders and (ii) do not provide that the debt securities shall thereby become redeemable or repayable in accordance with the terms of the debt securities), the trustee may, and if so requested by the holders of not less than 25% in principal amount of the outstanding debt securities will, declare the principal amount together with accrued interest, if any, with respect to the debt securities due and payable immediately, by a notice in writing to us (and to the trustee if given by the holder or holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.

With respect to the Fixed Rate/Floating Rate Notes, at any time after such declaration, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in aggregate principal amount of the debt securities, by written notice to us and the trustee, may rescind or annul such declaration of acceleration and its consequences, but only if we have paid to or deposited with the trustee a sum sufficient to pay:

–the principal of the debt securities which has become due otherwise than by such declaration of acceleration and any due and payable interest, and overdue interest, if any, thereon at the relevant rate; and

–all sums paid or advanced by the trustee pursuant to the indenture and the reasonable compensation, expenses, disbursements and advances of the trustee, its agents and counsel.

With respect to the Fixed Rate/Floating Rate Notes and the 1.532% Fixed Rate Resetting Notes due 2026, subject to the paragraph below relating to circumstances in which a relevant failure will not be a default, it will be a default with the respect to a series of debt securities if:

–we fail to pay an installment of interest upon any of the debt securities and such default continues for 14 days; or

–we fail to pay the principal of the debt securities at their maturity and such failure continues for 14 days.

If a default occurs, the trustee may institute proceedings in England (but not elsewhere) for our winding up; provided that the trustee may not, upon the occurrence of a default on the debt securities, accelerate the maturity of any principal, interest or other amount in respect of any of the debt securities (except in a winding up as provided above).

Notwithstanding the foregoing, failure to make any payment in respect of a series of debt securities will not be a default in respect of such debt securities if such payment is withheld or refused:

–in order to comply with any fiscal or other law or regulation or with the order of any court of competent jurisdiction, in each case applicable to such payment; or

–in case of doubt as to the validity or applicability of any such law, regulation or order, in accordance with advice given as to such validity or applicability at any time during the said grace period of 14 days by independent legal advisers acceptable to the trustee,

provided, however, that the trustee may, by notice to us, require us to take such action (including but not limited to proceedings for a declaration by a court of competent jurisdiction) as the trustee may be advised in an opinion of counsel, upon which opinion the trustee may

conclusively rely, is appropriate and reasonable in the circumstances to resolve such doubt, in which case, we will forthwith take and expeditiously proceed with such action and will be bound by any final resolution of the doubt resulting therefrom. If any such resolution determines that the relevant payment can be made without violating any applicable law, regulation or order then the preceding sentence will cease to have effect and the payment will become due and payable on the expiration of the relevant grace period of 14 days after the trustee gives written notice to us informing us of such resolution.

Limitation of Remedies

The holder or holders of not less than a majority in aggregate principal amount of the outstanding debt securities of any series may waive any past default with respect to the series, except a default in respect of the payment of interest, if any, or principal of (or premium, if any) or payments on any debt security or a covenant or provision of the applicable indenture which cannot be modified or amended without the consent of each holder of debt securities of such series. The holders shall provide written notice to the trustee of such waiver.

Subject to the provisions of the relevant indenture relating to the duties of the trustee, if an Event of Default occurs and is continuing with respect to the debt securities of any series, the trustee will be under no obligation to any holder or holders of the debt securities of the series, unless they have offered reasonable indemnity or security satisfactory to the trustee.

The indentures provide that the trustee will, within 90 days after the occurrence of an Event of Default of which a responsible officer of the trustee has written notice with respect to the debt securities of any series known to it, give to each holder of the debt securities of the affected series notice of the Event of Default unless the Event of Default has been cured or waived. However, the trustee shall be protected in withholding notice if it determines in good faith that withholding notice is in the interest of the holders.

We are required to furnish to the trustee annually a statement as to our compliance with all conditions and covenants under the indentures.

Covenants

Fixed Rate Notes

Under the terms of the Fixed Rate Notes, the United Kingdom (or any political subdivision thereof or therein having the power to tax) may require us to withhold or deduct amounts from payments of principal or interest on the applicable series of debt securities, for taxes or other governmental charges. If such a withholding or deduction is required, we may be required to pay additional amounts such that the net amount paid to holders of such debt securities, after such deduction or withholding, equals the amount that would have been payable had no such withholding or deduction been required.

All payments in respect of the applicable series of debt securities will be made subject to any withholding or deduction required pursuant to FATCA, and we shall not be required to pay additional amounts with respect to the principal of, interest and any other payments on, such debt securities on account of any such deduction or withholding required pursuant to FATCA.

We can legally release ourselves from any payment or other obligations on the applicable series of debt securities, except for various obligations described below, if such debt securities have become due and payable or will become due and payable at their stated maturity within one year or are to be called for redemption within one year or are to be exchanged for stock or other securities and notice of such exchange has been given and we deposit in trust with the trustee for the benefit of the holders of such debt securities and the benefit of all other direct holders of such debt securities, a combination of money or U.S. government obligations (with respect to securities denominated in dollars) or foreign government obligations (with respect to securities denominated in the same foreign currency) that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates. In addition, on the date of such deposit, we must not be in default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described under the section “Events of Default.” A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded. However, even if we take these actions, a number of our obligations under the indenture will remain.

The 2015 Senior Indenture does not contain any covenants or other provisions designed to protect holders of the debt securities against a reduction in our creditworthiness in the event of a highly leveraged transaction or that would prohibit other transactions that might adversely affect holders of the debt securities, including, among other things, through the incurrence of additional indebtedness

Fixed Rate/Floating Rate Notes and the 1.532% Fixed Rate Resetting Notes due 2026

Under the terms of the Fixed Rate/Floating Rate Notes and the 1.532% Fixed Rate Resetting Notes due 2026, the United Kingdom (or any political subdivision thereof or therein having the power to tax) may require us to withhold or deduct amounts from payments of principal or interest on the applicable series of debt securities, for taxes or other governmental charges. If such a withholding or deduction is required, we may be required to pay additional amounts such that the net amount paid to holders of the debt securities, after such deduction or withholding, equals the amount that would have been payable had no such withholding or deduction been required.

All payments in respect of the debt securities will be made subject to any withholding or deduction required pursuant to FATCA, and we shall not be required to pay additional amounts with respect to the principal of, interest and any other payments on, the debt securities on account of any such deduction or withholding required pursuant to FATCA.

We can legally release ourselves from any payment or other obligations on the applicable series of debt securities, except for various obligations described below, if, inter alia, either:

–all debt securities of such series theretofore authenticated and delivered have been delivered to the trustee for cancellation; or

–the debt securities of such series not theretofore delivered to the trustee for cancellation have become due and payable or will become due and payable at their stated maturity within one year or are to be called for redemption within one year or are to be exchanged for stock or other securities and notice of such exchange has been given; and

we deposit in trust with the trustee for the benefit of all direct holders of debt securities, a combination of money or U.S. government obligations (with respect to securities denominated in dollars) or foreign government obligations (with respect to securities denominated in the same foreign currency) that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates. In addition, on the date of such deposit, we must not be in default. For purposes of this no-default test, a default would

include an event of default that has occurred and not been cured, as described under the section “Defaults and Events of Default.” A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded. However, even if we take these actions, a number of our obligations under the relevant indenture will remain.

Any discharge will be subject to the consent of the PRA, if required.

The 2017 Senior Indenture does not contain any covenants or other provisions designed to protect holders of the debt securities against a reduction in our creditworthiness in the event of a highly leveraged transaction or that would prohibit other transactions that might adversely affect holders of the debt securities, including, among other things, through the incurrence of additional indebtedness.

Agreement with Respect to the Exercise of UK Bail-in Power

Notwithstanding any other term of the debt securities, the indentures or any other agreements, arrangements, or understandings between us and any holder of debt securities, by its acquisition of the debt securities, each holder of debt securities (including each holder of a beneficial interest in the debt securities) acknowledges, accepts, agrees to be bound by and consents to: (a) the effect of the exercise of a U.K. bail-in power (as defined below) by the relevant UK resolution authority (as defined below) whether or not imposed with prior notice, that may include and result in any of the following, or some combination thereof: (i) the reduction of all, or a portion, of the Amounts Due (as defined below); (ii) the conversion of all, or a portion, of the Amounts Due on the debt securities into shares, other securities or other obligations of ours or another person (and the issue to or conferral on the holders of debt securities of such shares, securities or obligations), including by means of an amendment, modification or variation of the terms of the debt securities; (iii) the cancellation of the debt securities; (iv) the amendment or alteration of the maturity of the debt securities or amendment of the amount of interest payable on the debt securities, or the date on which the interest becomes payable, including by suspending payment for a temporary period; and (b) the variation of the terms of the debt securities, if necessary, to give effect to the exercise of the UK bail-in power by the relevant UK resolution authority.

For these purposes, “Amounts Due” are the principal amount of, and accrued but unpaid interest, including any Additional Amounts (as defined above) due on, the debt securities. References to principal and interest will include payments of principal and interest that have become due and payable but which have not been paid, prior to the exercise of any UK bail-in power by the relevant UK resolution authority.

The “UK bail-in power” is any write-down, conversion, transfer, modification, or suspension power existing from time to time under, and exercised in compliance with, any laws, regulations, rules or requirements in effect in the United Kingdom, relating to the transposition of Directive 2014/59/EU establishing a framework for the recovery and resolution of credit institutions and investment firms as amended from time to time (“BRRD”), including but not limited to the UK Banking Act 2009, as the same may be amended form time to time, including by the Financial Services (Banking Reform) Act 2013 (the “Banking Act”), and the instruments, rules and standards created thereunder, pursuant to which: (i) any obligation of a regulated entity (or other affiliate of such regulated entity) can be reduced, cancelled, modified, or converted into shares, other securities, or other obligations of such regulated entity or any other person (or suspended for a temporary period); and (ii) any right in a contract governing an obligation of a regulated entity may be deemed to have been exercised.

We refer to such agreements and acknowledgments with respect to the exercise of the UK bail-in power as the “bail-in consent.”

A reference to a “regulated entity” is to any BRRD undertaking as such term is defined under the PRA Rulebook promulgated by the United Kingdom Prudential Regulation Authority, as amended form time to time, which includes, certain credit institutions, investment firms, and certain of their parent or holding companies and a reference to the “relevant UK resolution authority” is to the Bank of England or any other authority with the ability to exercise a UK bail-in power.

No Amounts Due on any series of debt securities, will become due and payable or be paid after the exercise of any UK bail-in power by the relevant UK resolution authority if and to the extent such Amounts Due have been reduced, converted, cancelled, amended or altered as a result of such exercise.

By its acquisition of the debt securities, each holder of the debt securities (including each holder of a beneficial interest in the debt securities), to the extent permitted by the Trust Indenture Act, will waive any and all claims, in law and/or in equity, against the trustee for, agree not to initiate a suit against the trustee in respect of, and agree 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 debt securities.

Upon the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the debt securities, we will provide a written notice to the holders of the debt securities through DTC as soon as practicable regarding such exercise of the UK bail-in power. We will also deliver a copy of such notice to the trustee for information purposes.

Neither a reduction or cancellation, in part or in full, of the Amounts Due, the conversion thereof into another security or obligation of us or another person, as a result of the exercise of the UK bail-in power by the relevant UK resolution authority with respect to us, nor the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the debt securities will be an Event of Default with respect to such debt securities.

By its acquisition of the debt securities, each holder of the debt securities (including each holder of a beneficial interest in the debt securities) acknowledges and agrees that neither a cancellation or deemed cancellation of the principal or interest (in each case, in whole or in part), nor the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the debt securities will give rise to an 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.

By its acquisition of the debt securities, each holder of the debt securities (including each holder of a beneficial interest in the debt securities) acknowledges and agrees that, upon the exercise of the UK bail-in power by the relevant UK resolution authority, (a) the trustee will not be required to take any further directions from the holders of debt securities with respect to any portion of the debt securities that are written-down, converted to equity and/or cancelled under Section 5.12 (Control by Holders) of the relevant indenture, and (b) the relevant indenture will 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. Notwithstanding the foregoing, if, following the completion of the exercise of the UK bail-in power by the relevant UK resolution

authority, the debt 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 debt securities), then the trustee's duties under the relevant indenture shall remain applicable with respect to the debt securities following such completion to the extent that we and the trustee shall agree pursuant to another supplemental indenture or an amendment to the relevant indenture; provided, however, that notwithstanding the exercise of the UK bail-in power by the relevant UK authority, so long as any debt securities remain outstanding, there will at all times be a trustee for the debt securities in accordance with the relevant indenture, and the resignation and/or removal of the trustee and the appointment of a successor trustee will continue to be governed by the relevant indenture, including to the extent no additional supplemental indenture or amendment is agreed upon in the event the debt securities remain outstanding following the completion of the exercise of the UK bail-in power.

By its acquisition of the debt securities, each holder of the debt securities (including each holder of a beneficial interest in the debt securities) shall be deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary through which it holds such debt securities to take any and all necessary action, if required, to implement the exercise of any UK bail-in power with respect to such debt securities as it may be imposed, without any further action or direction on the part of such holder or the trustee. In addition, the exercise of the UK bail-in power may require that interests in the debt securities be held and/or other actions implementing the UK bail-in power to be taken, as the case may be, through clearing systems, intermediaries or persons other than DTC.
