 Exhibit 10.2 

UNIT APPRECIATION RIGHTS AGREEMENT 
 UNDER THE 
 STONEMOR PARTNERS L.P. LONG-TERM INCENTIVE PLAN

 This Key Employee Unit Appreciation Rights Agreement (the “Agreement”) entered into as of April 2, 2012,
(the “Agreement Date”), by and between StoneMor GP LLC (the “Company”), the general partner of and acting on behalf of StoneMor Partners L.P., a Delaware limited partnership (the “Partnership”),
and                    , a key employee of the Company or its Affiliates (the “Participant”). 

BACKGROUND: 
 In order to make certain awards to key employees, directors and consultants of the Company and its Affiliates, the Company maintains on behalf of the Partnership the StoneMor Partners L.P. Long-Term
Incentive Plan (the “Plan”). The Plan is administered by the Compensation Committee (the “Committee”) of the Board of Directors (“Board”) of the Company. The Committee has determined to grant to the Participant,
pursuant to the terms and conditions of the Plan, an award (the “Award”) of Unit Appreciation Rights Agreement (also called “UARS”), which entitles the holder to receive, in whole Common Units of the Partnership (“Common
Units”) the excess of the Fair Market Value of a Common Unit on the exercise date over the exercise base price established for the UARS, subject to the terms and conditions contained herein. The exercise base price for the UAR is intended to
equal to Fair Market Value of a Common Unit on the Date of Grant (as defined herein). The Participant has determined to accept such Award. Any initially capitalized terms and phrases used in this Agreement, but not otherwise defined herein, shall
have the respective meanings ascribed to them in the Plan. 
 NOW, THEREFORE, the Company, acting on behalf of the Partnership,
and the Participant, each intending to be legally bound hereby, agree as follows: 
 ARTICLE I 

AWARD OF UARS 
 1.1 Grant of UARS and Vesting. The Participant is hereby granted the following UARS under the Plan and the following terms shall have the following respective meanings as used hereafter in this
Agreement: 
  

					
	 Date of Grant
	  	April 2, 2012	 
	 Exercise Base Price for Each of the UARS*
	  	$	24.36	  
		  	  
	  
	 
	 Total Number of UARS
	  			
		  	  
	  
	 

 UARS vest at a percentage rate which is equal to a fraction the numerator of which is the number of
calendar months which have elapsed since April 2, 2012 and the denominator of which is 48, subject to the forfeiture provisions contained in Section 1.4 hereof. 
 All of the UARS shall automatically vest upon a Change of Control (as defined in the Plan), notwithstanding that the UARS have not otherwise vested, provided that, at the time of 

	 	

  

	*	Intended to Equal Fair Market Value on Date of Grant

the Change of Control, the Participant is then employed by the Company or any of its Affiliates. All of the UARS shall automatically vest upon retirement at or after age 60 of a Participant who
has at least 25 years of service with the Company or any of its predecessor’s companies (as determined by the Committee). 

The term “permanent disability”, as used in Section 1.4, shall refer to a “disability” as defined in Regulation
1.409A-3(i)(4)(i) and any successor guidance under the Code. All decisions as to whether UARS have fully vested or as to whether a Participant has suffered a “permanent disability” shall be made by the Committee and its decision shall be
final, binding and conclusive in the absence of clear and convincing evidence that such decision was not made in good faith. 

1.2 Exercise of UARS. 
 (a) UARS may not be exercised prior to vesting, and only to the extent vested, and exercise is subject to all the terms and conditions of the Plan, including, but not limited to, the conditions set forth
in Section 1.2(c) hereof. UARS which have vested may be exercised by giving written exercise notice to the Company on the form supplied by the Company. UARS are not deemed exercised until the Participant has paid or made suitable arrangements
to pay all required tax withholding under Section 2.3 hereof, which will include (i) all foreign, federal, state and local income tax withholding required to be withheld by the Company in connection with the exercise of the UARS and
(ii) the employee’s portion of other foreign, federal, state and local payroll and other taxes due in connection with the exercise of the UARS. 
 (b) Upon proper exercise of UARS, the Participant will be entitled to receive, with respect to the UARS which are exercised, that number of whole Common Units that is closest in Fair Market Value (but
does not exceed) the excess (if any) of (i) the Fair Market Value of the Common Units on the last trading date preceding the receipt by the Company of the written exercise notice (or if there is no trading in the Common Units on such date, on
the next preceding date on which there was trading) as reported in The Wall Street Journal (or other reporting service approved by the Committee) over (ii) the Exercise Base Price For Each of the UARS contained in Section 1.1. No
fractional Common Units shall be issued; instead, cash shall be distributed equal in Fair Market Value to the value of a whole Common Unit multiplied by the fraction. In the event Common Units are not publicly traded at the time a determination of
Fair Market Value is required to be made herein, the determination of Fair Market Value shall be made in good faith by the Committee. The Committee’s determination of Fair Market Value shall be final, binding and conclusive in absence of clear
and convincing evidence that such decision was not made in good faith. 
 (c) The Plan provides as follows: “The Committee
may refuse to issue or transfer any Units or other consideration under an Award if, in its sole discretion, it determines that the issuance or transfer of such Units or such other consideration might violate any applicable law or regulation, the
rules of the principal securities exchange on which the Units are then traded, or entitle the Partnership or an Affiliate to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company by a Participant,
other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary.” The exercise of UARS may be subject to approval by the limited partners of the Partnership
as required by the listing rules of the New Stock Exchange. In no event may a UAR be exercised in violation of the Second Amended and Restated Agreement of Limited Partnership of the Partnership.

 1.3 Exercise Term. Subject to Section 1.4 hereof, UARS’ may not be
exercised more than five (5) years after the Date of Grant contained in Section 1.1. 
 1.4 Forfeiture of UARS Upon
Termination of Employment. In the event of the termination of the employment of the Participant (whether voluntary or involuntary and regardless of the reason for the termination) with the Company or its Affiliates, all UARS (whether or not
vested) shall be deemed to be automatically forfeited, unless the Participant’s employment is on that date transferred to the Company or another Affiliate. If a Participant’s employment is with an Affiliate and that entity ceases to be an
Affiliate, the Participant’s employment will be deemed to have terminated when the entity ceases to be an Affiliate unless the Participant transfers employment to the Company or its remaining Affiliates. Notwithstanding the foregoing, in the
event of the termination of the Participant’s employment with the Company or any of its Affiliates by reason of (a) a Change of Control (as defined in the Plan); (b) the death of the Participant; (c) the permanent disability of
the Participant (as determined by the Committee); or (d) the retirement of the Participant at such age as the Committee shall approve, no forfeiture shall apply. 
 1.5 No Rights as Holder of Common Units. The Participant is not entitled to the rights of a holder of Common Units (including, but not limited to, the right to receive distributions on Common
Units) until certificates representing the Common Units have been delivered to the Participant after proper exercise of the UARS. 
 ARTICLE II

2.1 No Right Of Continued Employment. The receipt of this Award does not give the Participant, and nothing in the Plan or in this
Agreement shall confer upon the Participant, any right to continue in the employment of the Company or any of its Affiliates. Nothing in the Plan or in this Agreement shall affect any right which the Company or any of its Affiliates may have to
terminate the employment of the Participant. 
 2.2 No Rights As A Limited Partner. Neither the Participant nor any other
person shall be entitled to the privileges of ownership of Common Units of the Partnership, limited partnership interests in the Partnership, or otherwise have any rights as a limited partner, by reason of the award of the UARS covered by this
Agreement. 
 2.3 Tax Withholding. The Participant is responsible to pay to the Company all required tax withholding,
whether foreign, federal, state or local in connection with the exercise of the UARS.

August 7 of each year, commencing on August 7, 2013 at the rate of 4.375% per annum, until the principal hereof is paid or made available for payment; provided that any principal of, and any premium and interest on, this Note
which is overdue shall bear interest (to the extent that payment thereof shall be legally enforceable) at the rate per annum then borne by this Note from the date such amount is due to but not including the day it is paid or made available for
payment, and such overdue interest shall be paid as provided in Section 306 of the Base Indenture. 
 Interest on the Notes
shall be calculated on the basis of a 365-day year or, in the case of an Interest Payment Date falling in a leap year, a 366-day year, and the actual number of days elapsed from and including the last Interest Payment Date (or, with respect to
interest payable on the first Interest Payment Date, from the issue date of this Note) to but excluding the Interest Payment Date on which the interest payment falls due. 
 The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date shall, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more
Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest, which shall be the August 1 (whether or not a Business Day) next preceding such Interest Payment Date. Any such interest not so punctually
paid or duly provided for on any Interest Payment Date 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 Note (or one or more Predecessor Notes) is registered at the
close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of this Note not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any securities exchange on which this Note may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture.

 Payment of the principal of, and premium, if any, and interest on, this Note shall be made
at the office of the Trustee or agency of the Company in the Borough of Manhattan, The City of New York, New York and at the Office of the London Paying Agent and, if and for so long as the Notes are admitted to listing on the Official List of the
Luxembourg Stock Exchange and trading on the Euro MTF, at the office of the Luxembourg Paying Agent, in each case maintained for such purpose and at any other office or agency maintained by the Company for such purpose, in pounds sterling (or euro,
if the United Kingdom adopts the euro) against surrender of this Note in the case of any payment due at the Maturity of the principal thereof (other than any payment of interest that first becomes payable on a day other than an Interest Payment
Date); provided, however, that at the option of the Company, payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. [If the Note is a Global
Note, then insert — Notwithstanding the foregoing, payment of any amount payable in respect of a Global Note shall be made in accordance with the Applicable Procedures of the Depositary.] 

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further 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 the Trustee referred to on the reverse hereof by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

 (b) Form of Reverse of Note. 

This Note is one of a duly authorized issue of securities of the Company (the “Notes”), issued under an Indenture, dated as of
June 28, 2012 (the “Base Indenture”), between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), Security Registrar, Paying Agent and
Transfer Agent, as supplemented by the Fourth Supplemental Indenture dated as of August 7, 2012 (the “Fourth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) among the Company, the Trustee, The
Bank of New York Mellon, London Branch, as London Paying Agent and The Bank of New York Mellon (Luxembourg) S.A., as Luxembourg Paying Agent and Luxembourg Transfer Agent and reference is hereby made to the Indenture for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms, conditions and
provisions of this Note are those stated in the Indenture (including those made a part of the Indenture by reference to the Trust Indenture Act) and those set forth in this Note. This Note is one of the series designated on the face hereof.

 Additional notes on terms and conditions identical to those of this Note (except for issue date, issue price and the date
from which interest shall accrue and, if applicable, first be paid) may be issued by the Company without the consent of the Holders of the Notes. The amount evidenced by such additional Notes shall increase the aggregate principal amount of, and
shall be consolidated and form a single series with, the Notes, in which case the Schedule of Increases and Decreases in Global Note attached hereto will be correspondingly adjusted. 

If, prior to August 7, 2041, the United Kingdom adopts the euro as its lawful currency in accordance with the Treaty Establishing
the European Community, as amended from time to time, this Note will be re-denominated into euro, and the regulations of the European Commission relating to the euro shall apply to this Note as so re-denominated. The circumstances and consequences
described in this paragraph will not entitle the Company, the Trustee or any Holder of this Note to redeem early, rescind or receive notice relating to this Note, repudiate the terms of this Note or the Indenture, raise any defense, request any
compensation or make any claim, nor will these circumstances and consequences affect any of the Company’s other obligations under this Note or the Indenture. 
 In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Note shall not be a Business Day, then (notwithstanding any other provision of the Indenture or of the Notes) payment
of principal and premium, if any, or interest need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date or at the Stated Maturity, as
the case may be; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be. 

In the event of redemption of this Note in part only, a new Note or Notes of this series and of like tenor for the unredeemed portion
hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 If an Event of Default with respect to
Notes shall occur and be continuing, the principal of all of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 

  
 7 

 All payments of principal, premium, if any, and interest in respect of the Notes shall be
made after withholding or deduction for any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or on behalf of Mexico or any authority therein or thereof having
power to tax (“Mexican Taxes”). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional amounts (“Additional Amounts”) as will result in receipt by the Holders of Notes on the
respective due dates of such amounts as would have been received by them had no such withholding or deduction (including for any Mexican Taxes payable in respect of Additional Amounts) been required, except that no such Additional Amounts shall be
payable with respect to any payment on a Note to the extent: 
 (i) that any such taxes, duties, assessments or
other governmental charges are imposed solely because of (A) a connection between the Holder and Mexico other than the ownership or holding of such Note and the mere receipt of payments with respect to such Note or (B) failure by the
Holder or any other Person to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with Mexico of the Holder or any beneficial owner of such Note if compliance is
required by law, regulation or by an applicable income tax treaty to which Mexico is a party, as a precondition to exemption from, or reduction in the rate of, the tax, assessment or other governmental charge and we have given the Holders at least
30 days’ notice prior to the first payment date with respect to which such certification, identification or reporting requirement is required to the effect that Holders will be required to provide such information and identification;

 (ii) of any such taxes, duties, assessments or other governmental charges with respect to such Note presented
for payment more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that the Holder of
such Note would have been entitled to such Additional Amounts on presenting such Note for payment on any date during such 15-day period; 
 (iii) of estate, inheritance, gift or other similar taxes, assessments or other governmental charge imposed with respect to such Note; 

(iv) of any tax, duty, assessment or other governmental charge payable otherwise than by deduction or withholding from
payments on such Note; 
 (v) of any payment on such Note to a Holder who is a fiduciary or partnership or a
person other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have been entitled to the
Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Note; 

(vi) of any tax, duty, assessment or other governmental charge imposed on a payment to an individual and required to be
made pursuant to European Council Directive 2003/48/EC on the taxation of savings income or any other directive implementing the conclusions of the ECOFIN Council meetings of November 26 and 27, 2000, December 13, 2001, and
January 21, 2003, or any law or agreement implementing or complying with, or introduced in order to conform to, such a directive; and 
 (vii) any combination of the items in clauses (i) through (vi) above. 

  
 8 

 For purposes of the provisions described in Clause (i) above, the term
“Holder” of any Note means the direct nominee of any beneficial owner of such Note, which holds such beneficial owner’s interest in such Note. Notwithstanding the foregoing, the limitations on the Company’s obligation to pay
Additional Amounts set forth in Clause (i)(B) above shall not apply if (a) the provision of information, documentation or other evidence described in such Clause (i)(B) would be materially more onerous, in form, in procedure or in the substance
of information disclosed, to a Holder or beneficial owner of a Note (taking into account any relevant differences between U.S. and Mexican law, regulation or administrative practice) than comparable information or other reporting requirements
imposed under U.S. tax law (including the United States—Mexico Income Tax Treaty), regulations (including proposed regulations) and administrative practice or (b) Rule I.3.17.11 (or any successor provision) is in effect, unless the
provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by statute, regulation, rule or administrative practice in order to apply Rule I.3.17.11 (or any successor provision) and the Company
cannot obtain such information, documentation or other evidence on its own through reasonable diligence and the Company otherwise would meet the requirements for application of Rule I.3.17.11 (or any successor provision). In addition, such Clause
(i)(B) shall not be construed to require that a non-Mexican pension or retirement fund or a non-Mexican financial institution or any other Person register with the Ministry of Finance and Public Credit for the purpose of establishing eligibility for
an exemption from or reduction of Mexican withholding tax. 
 The Company shall provide the Trustee with the constancia
or other relevant documentation, if any (which may consist of certified copies of such documentation), satisfactory to the Trustee evidencing the payment of Mexican Taxes in respect of which the Company has paid any Additional Amounts. Copies of
such documentation shall be made available to the Holders of the Notes or any Paying Agent, as applicable, upon request therefor. 
 The Company shall pay all stamp, issue, registration, documentary or other similar duties, if any, which may be imposed by Mexico or any governmental entity or political subdivision therein or thereof, or
any taxing authority of or in any of the foregoing, with respect to the Indenture or the issuance of the Notes. 
 All
references herein and in the Indenture to principal, premium, if any, interest or any other amount payable in respect of any Note shall be deemed to include all Additional Amounts, if any, payable in respect of such principal, premium, interest or
other amount payable, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such
express mention is not made. 
 In the event that Additional Amounts actually paid with respect to the Notes pursuant to the
preceding paragraphs are based on rates of deduction or withholding of withholding taxes in excess of the appropriate rate applicable to the Holder of such Notes, and, as a result thereof such Holder is entitled to make claim for a refund or credit
of such excess from the authority imposing such withholding tax, then such Holder shall, by accepting such Notes, be deemed to have assigned and transferred all right, title, and interest to any such claim for a refund or credit of such excess to
the Company. However, by making such assignment, the Holder makes no representation or warranty that the Company will be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto. 

All references herein and in the Indenture to principal in respect of any Note shall be deemed to mean and include any Redemption Price
payable in respect of such Note pursuant to any redemption right hereunder (and all such references to the Stated Maturity of the principal in respect of 

  
 9 

 
any Note shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price), and all such references to principal, premium, interest or Additional Amounts shall be
deemed to mean and include any amount payable in respect hereof pursuant to Section 1009 of the Base Indenture. 
 The
Company may, at its option, redeem the Notes upon not less than 30 nor more than 60 days’ notice, at any time and, only in the case of clause (ii) below, from time to time: 

(i) in whole but not in part, at a Redemption Price equal to the sum of (A) 100% of the principal amount of the Notes
being redeemed, (B) accrued and unpaid interest thereon to the Redemption Date and (C) any Additional Amounts which would otherwise be payable thereon up to but not including the Redemption Date, solely if, as a result of any amendment to,
or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation or application of such laws,
rules or regulations, which amendment to or change in such laws, rules or regulations becomes effective on or after August 7, 2012, the Company would be obligated, after making reasonable endeavors to avoid such requirement, to pay Additional
Amounts in excess of the Additional Amounts that the Company would be obligated to pay if payments made on the Notes were subject to withholding or deduction of Mexican Taxes at the rate of 4.9%; provided, however, that (1) no notice of
redemption pursuant to this clause (i) may be given earlier than 90 days prior to the earliest date on which the Company would be obligated to pay such Additional Amounts if a payment on the Notes were then due and (2) at the time such
notice of redemption is given, the Company’s obligation to pay such Additional Amounts remains in effect; and 
 (ii) in whole or in part, at a Redemption Price equal to the greater of (1) 100% of the outstanding principal amount of the Notes being redeemed and (2) the sum of the present values of the
remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on an annual basis (calculated using a 365-day year or a 366-day year, as applicable, and the
actual number of days elapsed) at the Sterling Benchmark Rate plus 32 basis points, plus, in the case of (1) and (2), accrued and unpaid interest on the principal amount of such Notes to but not including the Redemption Date. 

For purposes of clause (ii) above, the following terms shall have the specified meanings: 

“Sterling Benchmark Rate” means, as of any Redemption Date, the rate per annum equal to the annual equivalent yield to maturity
or interpolated maturity of the Comparable Sterling Benchmark Issue, assuming a price for the Comparable Sterling Benchmark Issue (expressed as a percentage of its principal amount) equal to the Comparable Sterling Benchmark Price for such
Redemption Date. 
 “Comparable Sterling Benchmark Issue” means the U.K. Government security or securities selected by
an Independent Sterling Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed and that would be utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of sterling-denominated corporate debt securities of a comparable maturity to the remaining term of such Notes. 

  
 10 

 “Comparable Sterling Benchmark Price” means, with respect to any Redemption Date,
(i) the average of the Sterling Reference Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Sterling Reference Dealer Quotations or (ii) if the Trustee obtains fewer than four such Sterling Reference
Dealer Quotations, the average of all such quotations. 
 “Independent Sterling Investment Banker” means one of the
Sterling Reference Dealers appointed by the Company. 
 “Sterling Reference Dealer” means (i) Deutsche Bank AG,
London Branch or its affiliates which are primary securities dealers in securities of the U.K. Government, and their respective successors; provided that if any of the foregoing shall cease to be a primary government securities dealer of
securities of the U.K. Government (a “Primary Sterling Dealer”), the Company will substitute therefor another Primary Sterling Dealer and (ii) any other four Primary Sterling Dealers selected by the Company. 

“Sterling Reference Dealer Quotation” means, with respect to each Sterling Reference Dealer and any Redemption Date, the
average, as determined by the Trustee, of the bid and asked prices for the Comparable Sterling Benchmark Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Sterling Reference Dealer at
11:00 a.m. (Central European Time) on the third business day preceding such Redemption Date. 
 The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, on the one hand, and the rights of the Holders of the Notes, on the other hand, at any time by the Company and the
Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions (1) permitting the Holders of a majority in principal amount of the Notes at the time
Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and (2) permitting the Holders of a majority in principal amount of the Notes at the time Outstanding, on behalf of
the Holders of all Notes, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and
of any Note 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 Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a
receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of not less than 25% in principal amount of
the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have
received from the Holders of a majority in principal amount of Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and
offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or premium, if any, and/or interest hereon on or after the respective due dates expressed
herein. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed. 

  
 11 

 As provided in the Indenture, and subject to certain limitations therein set forth
(including, without limitation, the restrictions on transfer under Section 304 of the Indenture), the transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office of the
Trustee or agency of the Company in any place where the principal of and any premium and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, shall be issued
to the designated transferee or transferees. 
 The Notes are issuable only in registered form without coupons in denominations
of £100,000 and integral multiples of £1,000 in excess thereof. As provided in the Indenture, and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of like tenor 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 the Company or the Trustee 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 Note for registration of transfer, the Company, the Trustee and any agent of the Company or of the
Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 [If the Note is a Global Note, then insert — This Note is a Global Note and is subject to the provisions of the
Indenture relating to Global Notes, including the limitations in Section 304 of the Indenture on transfers and exchanges of Global Notes.] 
 This Note and the Indenture shall be governed by, and construed in accordance with, the law of the State of New York. 
 All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
