(2)   
if a SOFR Index value does not so appear as specified in (1) above at the SOFR Determination Time, then (i) if a Benchmark
Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, then Compounded SOFR Index Rate shall

Section 3.04.         
SOFR Index Unavailability


 


(a)               
If SOFR IndexStart or SOFR IndexEnd is not published on the relevant Interest Determination Date and a Benchmark

Period, SOFRi for such day “i” shall be SOFR published in respect of the first preceding U.S. Government Securities
Business Day for which SOFR was published on the SOFR Administrator’s Website.


 






    11 


     


    

 


Section 3.05.         
Benchmark Transition Provisions


 


(a)               
If the Issuer or the Issuer’s designee (in consultation with the Issuer) determines that a Benchmark Transition Event and
related Benchmark Replacement Date have occurred prior to the applicable Reference Time in respect of any determination of the Benchmark
on any date, the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during
the Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates; provided that,
if the Issuer or its designee (in consultation with the Issuer) are unable to or do not determine a Benchmark Replacement in accordance
with the provisions below prior to 5:00 p.m. (New York time) on the relevant Interest Determination Date, the interest rate for the related
Floating Rate Interest Period will be equal to the interest rate in effect for the immediately preceding Floating Rate Interest Period
or, in the case of the Interest Determination Date prior to the first Floating Rate Period Interest Payment Date, the Initial Interest
Rate.


 


(b)               
In connection with the implementation of a Benchmark Replacement, the Issuer or the Issuer’s designee (in consultation with
the Issuer) will have the right to make changes to (1) any Interest Determination Date, Floating Rate Period Interest Payment Date,
Reference Time, business day convention or Floating Rate Interest Period, (2) the manner, timing and frequency of determining the
rate and amounts of interest that are payable on the Notes during the Floating Rate Period and the conventions relating to such determination
and calculations with respect to interest, (3) rounding conventions, (4) tenors and (5) any other terms or provisions of
the Notes during the Floating Rate Period, in each case that the Issuer or its designee (in consultation with the Issuer) determine, from
time to time, to be appropriate to reflect the determination and implementation of such Benchmark Replacement in a manner substantially
consistent with market practice (or, if the Issuer or its designee (in consultation with the Issuer) decide that implementation of any
portion of such market practice is not administratively feasible or determine that no market practice for use of the Benchmark Replacement
exists, in such other manner as the Issuer or its designee (in consultation with the Issuer) determine is appropriate (acting in good
faith)) (the “Benchmark Replacement Conforming Changes”). Any Benchmark Replacement Conforming Changes will apply to
Notes for all future Floating Rate Interest Periods.


 


(c)               
The Issuer will promptly give notice of the determination of the Benchmark Replacement, the Benchmark Replacement Adjustment and
any Benchmark Replacement Conforming Changes to the Trustee, the Paying Agent, the Calculation Agent and the Holders; provided
that failure to provide such notice will have no impact on the effectiveness of, or otherwise invalidate, any such determination.


 


(d)               
All determinations, decisions, elections and any calculations made by the Issuer or the Issuer’s designee for the purposes
of determining the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes will be
conclusive and binding on the Holders, the Issuer, the Calculation Agent, the Trustee and the Paying Agent, absent manifest error. If
made by the Issuer’s designee, such determinations, decisions, elections and calculations will be made after consulting with the
Issuer, and the Issuer’s designees will not make any such determination, decision, election or calculation to which the Issuer objects.
Notwithstanding anything to the contrary in the Indenture or the Notes, any determinations, decisions, calculations or elections made
in accordance with this provision will become effective without consent from the Holders or any other party.


 


(e)               
Any determination, decision or election relating to the Benchmark will be made by the Issuer on the basis described above. The
Calculation Agent shall have no liability for not making any such determination, decision or election. In addition, the Issuer may designate
an entity (which may be the Issuer’s Affiliate) to make any determination, decision or election that the Issuer has the right to
make in connection with the determination of the Benchmark.


 






    12 


     


    

 



 


(f)                
 Notwithstanding any other provision of “Benchmark Transition Provisions” set forth above, no Benchmark Replacement
will be adopted, nor will the applicable Benchmark Replacement Adjustment be applied, nor will any Benchmark Replacement Conforming Changes
be made, if in the Issuer’s determination, the same could reasonably be expected to prejudice the qualification of the Notes as
eligible liabilities or loss absorbing capacity instruments for the purposes of the Capital Rules.


 


(g)               
By its acquisition of the Notes, each Holder (which, for these purposes, includes each beneficial owner) (i) acknowledges, accepts,
consents and agrees to be bound by the Company’s or its designee’s determination of a Benchmark Transition Event, a Benchmark
Replacement Date, the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, including
as may occur without any prior notice from the Company and without the need for the Issuer to obtain any further consent from such Holder,
(ii) waives any and all claims, in law and/or in equity, against the Trustee, the Paying Agent and the Calculation Agent or the Issuer’s
designee for, agrees not to initiate a suit against the Trustee, the Paying Agent and the Calculation Agent or the Issuer’s designee
in respect of, and agrees that none of the Trustee, the Paying Agent or the Calculation Agent or the Issuer’s designee will be liable
for, the determination of or the failure or delay by the Issuer to determine any Benchmark Transition Event, any Benchmark Replacement
Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, and any losses
suffered in connection therewith and (iii) agrees that none of the Trustee, the Paying Agent or the Calculation Agent or the Issuer’s
designee will have any obligation to determine, confirm or verify any Benchmark Transition Event, any Benchmark Replacement Date, any
Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes (including any adjustments
thereto), including in the event of any failure or delay by the Issuer to determine any Benchmark Transition Event, any Benchmark Replacement
Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes.


 


(h)               
All percentages resulting from any calculation of any interest rate for the Notes will be rounded, if necessary, to the nearest
one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545%
(or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts would be rounded to the nearest cent, with one-half
cent being rounded upward.

(a) in making payment under the Senior

Amounts;


 


(c)               
Sections 11.09, 11.10 and 11.11 are hereby added at the end of Article 11 of the Base Indenture as follows:


 






    13 


     


    

 


Section 11.09. Optional Redemption
upon a Loss Absorption Disqualification Event. If a Loss Absorption Disqualification Event has occurred and is continuing, the Issuer
may exercise the Loss Absorption Disqualification Event Call Option, having given not less than 30 nor more than 60 days’ notice
to the Trustee, the Paying Agent, the Holders and the Registrar (which notice shall be irrevocable and shall specify the Loss Absorption

AMENDMENTS TO THE BASE INDENTURE
APPLICABLE TO ALL SERIES OF NOTES ISSUED ON OR AFTER THE DATE OF THIS SUPPLEMENTAL INDENTURE


 


Section 5.01.      
Section 10.04 of the Base Indenture is hereby amended with respect to Senior Debt Securities issued on or after the date hereof
as follows:


 


Section 10.04. Additional
Amounts. Unless otherwise specified in any Board Resolution establishing the terms of Senior Debt Securities of a series in
accordance with Section 3.01, all amounts of principal, and premium, if any, and interest, if any, on any series of Senior Debt
Securities will be paid by the Issuer 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 (“Taxes”) now or hereafter
imposed, levied, collected, withheld or assessed by or on behalf of the country in which the Issuer is 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. For the purposes of this Senior Debt Securities
Indenture, the phrase “fiscal or other laws, regulations and directives” shall include any obligation of the Issuer to
withhold or deduct from a payment pursuant to an agreement described in Section 1471(b) of the Code or otherwise imposed pursuant to
Sections 1471 through 1474 of the Code, any regulations thereunder or official interpretations thereof or any law implementing an
intergovernmental approach thereto (collectively, “FATCA”). If deduction or withholding of any such Taxes shall at any
time be required by the Taxing Jurisdiction, the Issuer will pay such additional amounts with respect to interest only (and not
principal) on any series of Senior Debt Securities (“Additional Amounts”) as may be necessary in order that the net
amounts paid to the Holders of Senior Debt Securities of the particular series, after such deduction or withholding, shall equal the
amounts which would have been payable in respect of such Senior Debt Securities had no such deduction or withholding been required; provided,
however, that the foregoing will not apply to any such Tax which would not have been payable or due but for the fact that:


 






    14 


     


    

 


		(i)	the Holder or the beneficial owner of the Senior Debt Security is a domiciliary, national or resident of, or engaging in business
or maintaining a permanent establishment or physically present in, the Taxing Jurisdiction or otherwise has some connection with the Taxing
Jurisdiction other than the holding or ownership of a Senior Debt Security, or the collection of any interest payments on any Senior Debt
Security of the relevant series;



 


		(ii)	except in the case of a winding-up of the Issuer in the United Kingdom, the relevant Senior Debt Security is presented (where presentation
is required) for payment in the United Kingdom;



 


		(iii)	the relevant Senior 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 such Additional Amount
on presenting (where presentation is required) the same for payment at the close of such 30 day period;



 


		(iv)	the Holder or the beneficial owner of the relevant Senior Debt Security or the beneficial owner of any payment of any interest on
such Senior Debt Security failed to comply with a request of the Issuer or its liquidator or other authorized person addressed to the
Holder (x) to provide information concerning the nationality, residence or identity of the Holder or such 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 the Taxing Jurisdiction as a precondition to exemption from all or part
of such tax, assessment or other governmental charge; or



 


		(v)	any combination of sub-clauses (i) through (iv) above;



 


nor shall Additional Amounts be paid with respect
to any interest on the Senior 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 Senior 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 the Issuer shall not be required
to pay Additional Amounts with respect to interest on the Senior Debt Securities on account of any such deduction or withholding required
pursuant to FATCA.


 


Whenever in this Senior Debt Securities Indenture
there is mentioned, in any context, the payment of any interest, on, or in respect of, any Senior Debt Security of any series such mention
shall be deemed to include mention of the payment of Additional Amounts provided for in this Section to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions hereof and as if express mention of the
payment of Additional Amounts (if applicable) were made in any provisions hereof where such express mention is not made.

Notwithstanding any other term of the Senior
Debt Securities represented by this Global Security or the Senior Debt Securities Indenture (as defined herein) or any other agreements,
arrangements or understandings between the Issuer and any Holder, by its acquisition of the Senior Debt Securities, each Holder of the
Senior Debt Securities (including for these purposes each holder of a beneficial interest in the Senior Debt Securities) acknowledges,
accepts, agrees to be bound by and consents to: (a) the effect of the exercise of any UK Bail-in Power (as defined herein) by the Relevant
UK Resolution Authority (as defined herein) arising in respect of the Senior Debt Securities, whether or not imposed with prior notice,
that may include and result in: (i) the reduction of all, or a portion, of the Amounts Due (as defined herein); (ii) the conversion of
all, or a portion, of the Amounts Due on the Senior Debt Securities into shares, other securities or other obligations of the Issuer or
another Person (and the issue to or conferral on the Holders of the Senior Debt Securities of such shares, securities or obligations)),
including by means of an amendment, modification or variation of the terms of the Senior Debt Securities; (iii) the cancellation of the
Senior Debt Securities including any other Amounts Due on the Senior Debt Securities; (iv) the amendment or alteration of the maturity

    1.673% Fixed Rate/Floating Rate Notes due 2027

     

	 


Santander UK Group Holdings plc, a public limited
company incorporated in England and Wales (hereinafter called the “Issuer,” which term shall include any successor
entity under the Senior Debt Securities Indenture), for value received, hereby promises to pay to Cede & Co., as nominee for DTC,
or registered assigns, upon presentation, the principal sum of [ ] DOLLARS ($[ ]) on June 14, 2027 (the “Maturity Date”).


 


The Issuer hereby promises to pay interest thereon:


 


(1)       from
(and including) June 14, 2021 to (but excluding) June 14, 2026 (the “Fixed Rate Period”) semi-annually in arrear on
June 14 and December 14 of each year (each, a “Fixed Rate Period Interest Payment Date”), beginning on December 14,
2021, at a rate of 1.673% per annum (the “Initial Interest Rate”); and


 


(2)        from
(and including) June 14, 2026 to (but excluding) the Maturity Date, (the “Floating Rate Period”), quarterly in arrear
on September 14, 2026, December 14, 2026, March 14, 2027 and the Maturity Date (each a “Floating Rate Period Interest Payment
Date” and, together with each Fixed Rate Period Interest Payment Date, an “Interest Payment Date”), at a
floating rate equal to the Benchmark plus 0.989% per annum (the “Margin”) (the “Floating Rate”). The interest
rate during the Floating Rate Period on this Senior Debt Security will be calculated quarterly on each Interest Determination Date.


 


The interest so payable, and punctually paid or
duly provided for on any Interest Payment Date will, as provided in the Senior Debt Securities Indenture, be paid to the Person in whose
name this Senior Debt Security is registered at the close of business on the Regular Record Date for such interest, which shall be the
fifteenth calendar day (whether or not a Business Day) preceding the related Interest Payment Date. Any such interest not so punctually
paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date, and may either be paid to the
Person in whose name this Senior Debt Security is registered at the close of business on a Special Record Date for the payment of Defaulted
Interest to be fixed by the Issuer, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Senior Debt Securities may be listed, and upon such notice as may be required by such exchange, all as
more fully provided in the Senior Debt Securities Indenture.


 


Payment of the principal of and interest on and
any Additional Amounts in respect of this Global Security will be paid to DTC for the purpose of permitting DTC to credit the principal
and interest received by it in respect of this Global Security to the accounts of the beneficial owners thereof; provided, however, that
if this Senior Debt Security is not a Global Security, payment of the principal of, interest on and Additional Amounts, if any, in respect
of this Senior Debt Security will be made at the office or agency of the Trustee in The City of New York, or elsewhere as provided in
the Senior Debt Securities Indenture, in such coin or currency of the United States of America as at the time of payment is legal tender
for payment of public and private debts; and provided, further, that at the option of the Issuer payment of interest may be made by (a)
check mailed to the address of the Person entitled thereto as such address shall appear in the Register or (b) transfer to an account
of the Person entitled thereto located inside the United States.

If a Fixed Rate Period Interest Payment Date or
a Redemption Date, as the case may be, would fall on a day that is not a Business Day, then the Fixed Rate Period Interest Payment Date,
or Redemption Date, as the case may be, will be postponed to the next succeeding Business Day, but no additional interest shall be paid
unless the Issuer fails to make payment on such next succeeding Business Day.


 


If any Floating Rate Period Interest Payment Date
(other than the Maturity Date or a Redemption Date) would fall on a day that is not a Business Day, then the Floating Rate Period 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 Period Interest
Payment Date will be the immediately preceding Business Day and interest thereon will accrue to but excluding such preceding Business
Day. If the Maturity Date or Redemption Date would fall on a day that is not a Business Day, then the payment of interest and principal
will be made on the next succeeding but no additional interest shall be paid unless the Issuer fails to make payment on such next succeeding
Business Day.


 


All amounts of principal, and premium, if any,
and interest, if any, on the Senior Debt Securities will be paid by the Issuer 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 (“Taxes”)
now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of the country in which the Issuer is 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. For the purposes of this Senior Debt Security, the phrase
 “fiscal or other laws, regulations and directives” shall include any obligation of the Issuer to withhold or deduct from a
payment pursuant to an agreement described in Section 1471(b) of the Internal Revenue Code of 1986, as amended (the “Code”)
or otherwise imposed pursuant to Sections 1471 through 1474 of the Code, any regulations thereunder or official interpretations thereof
or any law implementing an intergovernmental approach thereto (collectively, “FATCA”). If deduction or withholding of any
such Taxes shall at any time be required by the Taxing Jurisdiction, the Issuer will pay such additional amounts with respect to interest
only (and not principal) on the Senior Debt Securities (“Additional Amounts”) as may be necessary in order that the net amounts
paid to the Holders of Senior Debt Securities, after such deduction or withholding, shall equal the amounts which would have been payable
in respect of the Senior Debt Securities had no such deduction or withholding been required; provided, however, that the foregoing
will not apply to any such Tax which would not have been payable or due but for the fact that:


 


(i)       
the Holder or the beneficial owner of this Senior Debt Security is a domiciliary, national or resident of, or engaging in business
or maintaining a permanent establishment or physically present in, the Taxing Jurisdiction or otherwise has some connection with the Taxing
Jurisdiction other than the holding or ownership of this Senior Debt Security, or the collection of any interest payments on this Senior
Debt Security;


 


(ii)      
except in the case of a winding-up of the Issuer in the United Kingdom, this Senior Debt Security is presented (where presentation
is required) for payment in the United Kingdom;


 


(iii)     
this Senior 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 such Additional Amount on
presenting (where presentation is required) the same for payment at the close of such 30 day period;


 






    A-3 


     


    

 


(iv)     
 the Holder or the beneficial owner of this Senior Debt Security or the beneficial owner of any payment of any interest on this
Senior Debt Security failed to comply with a request of the Issuer or its liquidator or other authorized person addressed to the Holder
(x) to provide information concerning the nationality, residence or identity of the Holder or such 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 the Taxing Jurisdiction as a precondition to exemption from all or part of
such tax, assessment or other governmental charge; or


 


(v)      
any combination of sub-clauses (i) through (iv) above;


 


nor shall Additional Amounts be paid with respect
to any interest on the Senior 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 Senior 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 the Issuer shall not be required
to pay Additional Amounts with respect to interest on the Senior Debt Securities on account of any such deduction or withholding required
pursuant to FATCA.


 


Whenever in this Senior Debt Security there is
mentioned, in any context, the payment of any interest, on, or in respect of, the Senior Debt Securities such mention shall be deemed
to include mention of the payment of Additional Amounts provided for herein to the extent that, in such context, Additional Amounts are,
were or would be payable in respect thereof pursuant to the provisions hereof and as if express mention of the payment of Additional Amounts
(if applicable) were made in any provisions hereof where such express mention is not made.


 


A “Business Day” is 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.


 


Additional provisions of this Senior Debt Security
are set forth following the signature page hereof, which provisions shall for all purposes have the same effect as if set forth at this
place.


 


Unless the certificate of authentication hereon
has been executed by or on behalf of the Trustee referred to on the reverse hereof by manual signature, this Senior Debt Security shall
not be entitled to any benefit under the Senior Debt Securities Indenture or be valid or obligatory for any purpose.

or regulations of the Taxing Jurisdiction (including any treaty to which such Taxing Jurisdiction is a party) (as defined below), any

relevant Loss Absorption Regulations; provided that a Loss Absorption Disqualification Event shall not occur where the exclusion of the
Senior Debt Securities from the relevant minimum requirement(s) is due to the remaining maturity of the Senior Debt Securities being

As provided in and subject to the provisions of

series (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

Securities of this series due and payable immediately, by a notice in writing to the Issuer (and to the Trustee if given by the Holder

the Holder of this Senior Debt Security for the enforcement of any payment of principal hereof or interest hereon on or after the respective

    A-11


     


    

 


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 rights of the Holders of the Senior Debt Securities under the Senior Debt Securities Indenture at any time by the Issuer and
the Trustee with the consent of the Holders of not less than a majority in principal amount of the outstanding Senior Debt
Securities affected by such amendment. The Senior Debt Securities Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Senior Debt Securities at the time outstanding, on behalf of the Holders of all
Senior Debt Securities, to waive compliance by the Issuer 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 Senior Debt Security shall be conclusive and binding upon such Holder and upon all future Holders of this Senior Debt Security
and of any Senior Debt 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 Senior Debt Security.


 


No reference herein to the Senior Debt Securities
Indenture and no provision of this Senior Debt 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 Senior Debt Security at the times, place
and rate, and in the coin or currency, herein prescribed.


 


The Issuer may, from time to time, without the
consent of the Holders of the Senior Debt Securities, issue additional Senior Debt Securities of this series 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 Senior Debt Security; provided however that such additional Senior Debt Securities shall be issued under
a separate CUSIP, Common Code and/or ISIN number unless the additional Senior Debt Securities are issued pursuant to a “qualified
reopening” of the original series, are otherwise treated as part of the same “issue” of debt instruments as the original
series, or the original series was issued with no more than a de minimis amount of original issue discount and the additional Senior
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. Any such additional Senior Debt Securities, together with this Senior Debt 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 Senior Debt Security is registrable in the Register, upon surrender
of this Senior Debt 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 Senior Debt Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Issuer and the Registrar duly executed by the registered Holder hereof or his attorney duly authorized in writing,
and thereupon one or more new Senior Debt 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 Senior Debt Securities of this series are issuable
only in registered form without coupons in denominations of $200,000 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, Senior Debt Securities of this series are exchangeable
for a like aggregate principal amount of Senior Debt 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 Senior Debt Security
for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the Person in whose name this
Senior Debt Security is registered as the owner hereof for all purposes, whether or not this Senior Debt Security be overdue, and none
of the Issuer, the Trustee or any such agent shall be affected by notice to the contrary.

Debt Securities Indenture and this Senior Debt Security and all documents delivered in the name of the Issuer 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 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 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 any of them or any of their personal
assets for such satisfaction. The performance of the obligations of the Issuer under the Senior Debt Securities Indenture and this Senior
Debt Security and all documents delivered in the name of the Issuer in connection therewith shall not be deemed a waiver of any rights
or powers of the Issuer or its directors or shareholders under the Issuer’s Memorandum and Articles of Association.


 


Notwithstanding any other term of the Senior Debt
Securities or the Senior Debt Securities Indenture or any other agreements, arrangements or understandings between the Issuer and any
Holder of the Senior Debt Securities (including for these purposes each holder of a beneficial interest in the Senior Debt Securities),
by its acquisition of the Senior Debt Securities, each Holder of the Senior Debt Securities acknowledges, accepts, agrees to be bound
by and consents to:


 


(a) the effect of the exercise of any UK Bail-in
Power by the Relevant UK Resolution Authority arising in respect of the Senior Debt Securities, whether or not imposed with prior notice,
that may include and result in: (i) the reduction of all, or a portion, of the Amounts Due; (ii) the conversion of all, or a portion,
of the Amounts Due on the Senior Debt Securities into shares, other securities or other obligations of the Issuer or another Person (and
the issue to or conferral on the Holders of the Senior Debt Securities of such shares, securities or obligations), including by means
of an amendment, modification or variation of the terms of the Senior Debt Securities; (iii) the cancellation of the Senior Debt Securities
including any other Amounts Due on the Senior Debt Securities; and/or (iv) the amendment or alteration of the maturity of the Senior Debt
Securities or amendment of the amount of interest payable on the Senior Debt Securities, or the date on which the interest becomes payable,
including by suspending payment for a temporary period; and


 


(b) the variation, if necessary, of the terms of
the Senior Debt Securities Indenture or the Senior Debt Securities to give effect to the exercise of the UK Bail-in Power by the Relevant
UK Resolution Authority.


 


No Amounts Due on the Senior 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.


 


Notwithstanding any other provision of the Senior
Debt Securities Indenture or the Senior Debt Securities, neither a reduction or cancellation, in part or in full, of the Amounts Due,
the conversion thereof into another security or obligation of the Issuer or another Person, as a result of the exercise of the UK Bail-in
Power by the Relevant UK Resolution Authority with respect to the Issuer, nor the exercise of the UK Bail-in Power by the Relevant UK
Resolution Authority with respect to the Senior Debt Securities will be an Event of Default.


 


By its acquisition of the Senior Debt Securities,
each Holder of the Senior Debt Securities (which for these purposes includes each holder of a beneficial interest in the Senior Debt Securities):


 


(i) to the extent permitted by the Trust Indenture
Act, waives any and all claims, in law and/or in equity, 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 Senior Debt Securities;


 






    A-13


     


    

 





(ii) 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 Senior Debt Securities will give rise to a 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; and


 


(iii) acknowledges and agrees that, upon the exercise
of the UK Bail-in Power by the Relevant UK Resolution Authority:


 


(A) the Trustee shall not be required to take any
further directions from the Holders of the Senior Debt Securities with respect to any portion of the Senior Debt Securities that are written-down,
converted to equity and/or cancelled under Section 5.12 of the 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 the UK Bail-in Power by the Relevant UK Resolution Authority.


 


Notwithstanding clauses (i)-(iii) above, if, following
the completion of the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority, the Senior 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 Senior Debt Securities),
then the Trustee’s duties under the Senior Debt Securities Indenture shall remain applicable with respect to such Senior Debt Securities
following such completion to the extent the Issuer 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
Resolution Authority, so long as the Senior Debt Securities remain Outstanding, there will at all times be a Trustee for the Senior Debt
Securities in accordance with, Section 6.09 of the Senior Debt Securities Indenture, and the resignation and/or removal of the Trustee
and the appointment of a successor Trustee will continue to be governed by Sections 6.10 and 6.11 of the Senior Debt Securities Indenture,
respectively, including to the extent no additional supplemental indenture or amendment is agreed upon in the event the Senior Debt Securities
remain Outstanding following the completion of the exercise of the UK Bail-in Power.


 


Upon the exercise of the UK Bail-in Power by the
Relevant UK Resolution Authority with respect to the Senior Debt Securities, the Issuer will provide a written notice to DTC as soon as
practicable regarding such exercise of the UK Bail-in Power for the purposes of notifying the Holders of such occurrence. The Issuer will
also deliver a copy of such notice to the Trustee for information purposes. Each Holder of the Senior Debt Securities (including for these
purposes each holder of a beneficial interest in the Senior 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 the Senior Debt Securities to take any and all necessary
action, if required, to implement the exercise of the UK Bail-in Power with respect to the Senior Debt Securities as it may be imposed,
without any further action or direction on the part of such Holder or the Trustee.
