Purchasers of the Securities should not conclude that the inclusion of a futures contract in the Dow Jones-AIG Natural Gas Total Return Sub-IndexSM is any form of investment recommendation of the futures contract or the underlying exchange-traded physical commodity by Dow Jones, American International Group, AIG-FP or any of
their respective subsidiaries or affiliates. None of Dow Jones, American International Group, AIG-FP or any of their respective subsidiaries or affiliates has made any due diligence inquiries with respect to the

 OTHER TERMS: 
 All terms used in
this Security that are not defined in this Security but are defined in the Indenture referred to on the reverse of this Security shall have the meanings assigned to them in the Indenture. Section headings on the face of this Security are for
convenience only and shall not affect the construction of this Security. 
 “Business Day” means any day that is not a
Saturday, a Sunday or a day on which banking institutions in London or New York City generally are authorized or obligated by law, regulation or executive order to close. 
 “Default Amount” means, on any day, an amount in U.S. dollars, as determined by the Calculation Agent in its sole discretion, equal to the cost of having a Qualified Financial Institution (selected as
provided below) expressly assume the due and punctual payment of the principal of this Security, and the performance or observance of every covenant hereof and of the Indenture on the part of the Company to be performed or observed with respect to
this Security (or to undertake other obligations providing substantially equivalent economic value to the Holder of this Security as the Company’s obligations hereunder). Such cost will equal (i) the lowest amount that a Qualified
Financial Institution would charge to effect such assumption (or undertaking) plus (ii) the reasonable expenses (including reasonable attorneys’ fees) incurred by the Holder of this Security in 

  

 (Face of Security continued on next page) 
 -5- 








 
preparing any documentation necessary for such assumption (or undertaking). During the Default Quotation Period, each Holder of this Security and the Company
may request a Qualified Financial Institution to provide a quotation of the amount it would charge to effect such assumption (or undertaking). If either party obtains a quotation, it must notify the other party in writing of the quotation. The
amount referred to in clause (i) of this paragraph will equal the lowest (or, if there is only one, the only) quotation so obtained, and as to which notice is so given, during the Default Quotation Period; provided that, with respect to
any quotation, the party not obtaining the quotation may object, on reasonable and significant grounds, to the effectuation of such assumption (or undertaking) by the Qualified Financial Institution providing such quotation and notify the other
party in writing of such grounds within two Business Days after the last day of the Default Quotation Period, in which case that quotation will be disregarded in determining the Default Amount. The “Default Quotation Period” shall
be the period beginning on the day the Default Amount first becomes due and ending on the third Business Day after such due date, unless no such quotation is obtained, or unless every such quotation so obtained is objected to within five Business
Days after such due date as provided above, in which case the Default Quotation Period will continue until the third Business Day after the first Business Day on which prompt notice of a quotation is given as provided above, unless such quotation is
objected to as provided above within five Business Days after such first Business Day, in which case, the Default Quotation Period will continue as provided in this sentence. Notwithstanding the foregoing, if the Default Quotation Period (and the
subsequent two Business Day objection period) has not ended prior to the Final Valuation Date, then the Default Amount will equal the Face Amount. 
 “Final Valuation Date” means October 15, 2037, or if such date is not a Trading Day, the next succeeding Trading Day; provided, however, that if the Calculation Agent determines that a Market Disruption
Event occurs or is continuing on such date, the Final Valuation Date will be the first following Trading Day on which the Calculation Agent determines that a Market Disruption Event does not occur and is not continuing, provided that in no
event will the Final Valuation Date be postponed by more than five Trading Days. 
 “Index Component” means, with respect to
the Securities, the futures contract on natural gas that comprises the Index. 
 “Index Factor” means, on any given day, the
amount equal to the closing value of the Index on that day divided by the closing value of the Index on the Inception Date. 
 “Investor Fee” means the amount equal to 0.75% per year times the principal amount of the Holder’s Securities times the Index Factor, calculated on a daily basis in the following manner: (i) the
Investor Fee on the Inception Date shall equal zero; and (ii) on each subsequent calendar day until and including the Final Valuation Date or, in the case of Securities with respect to which the Holder has exercised its right of Early
Redemption, the applicable Valuation Date, the Investor Fee will increase by an amount equal to 0.75% times the principal amount of the Holder’s Securities times the Index Factor on that day (or, if such day is not a Trading Day,
the Index Factor on the immediately preceding Trading Day) divided by 365. 
 “Market Disruption Event” means, with
respect to the Securities, in the opinion of the Calculation Agent and determined in its sole discretion: (i) a material limitation, suspension or disruption in the trading of the Index Component which results in a failure by the trading
facility on which the relevant contract is traded to report a daily contract 

  

 (Face of Security continued on next page) 
 -6- 








 
reference price; (ii) the daily contract reference price for the Index Component has increased or decreased from the previous day’s daily contract
reference price by the maximum amount permitted under the applicable rules or procedures of the relevant trading facility; (iii) AIG-FP and Dow Jones fail to publish the closing value of the Index or the applicable trading facility or other
price source fails to announce or publish the daily contract reference price for the Index Component; (iv) any other event, if the Calculation Agent determines in its sole discretion that the event materially interferes with the ability of
Barclays Bank PLC or the ability of any affiliates of Barclays Bank PLC to unwind all or a material portion of a hedge with respect to the Securities that Barclays Bank PLC or any of its affiliates have effected or may effect. The following events
will not be Market Disruption Events: (a) a limitation on the hours or numbers of days of trading on a trading facility on which the Index Component is traded, but only if the limitation results from an announced change in the regular business
hours of the relevant market; or (b) a decision by a trading facility to permanently discontinue trading in the Index Component. 
 “Maturity Date” means October 22, 2037, provided that if such date is not a Business Day, the Maturity Date will be the next succeeding Business Day; provided, however, that if the fifth Business Day
preceding October 22, 2037 does not qualify as the Final Valuation Date referred to above, then the Maturity Date will be the fifth Business Day following the Final Valuation Date. 
 “Qualified Financial Institution” means, at any time, a financial institution organized under the laws of any jurisdiction in the United
States of America or Europe that at such time has outstanding debt obligations with a stated maturity of one year or less from the date of issue and rated A-1 or higher by Standard & Poor’s, a division of The McGraw Hill Companies,
Inc., Ratings Group (or any successor) or P-1 or higher by Moody’s Investors Service, Inc. (or any successor) or, in either case, such other comparable rating, if any, then used by such rating agency. 
 “Redemption Date” means the third Business Day following each Valuation Date other than the Final Valuation Date. The final Redemption
Date shall be the third Business Day following such Valuation Date that is immediately prior to the Final Valuation Date. 
 “Successor Index” means any substitute index approved by the Calculation Agent as a Successor Index pursuant to Section 3 hereof. 
 “Trading Day” means any day on which (i) the value of the Index is published by AIG-FP and Dow Jones; (ii) trading is generally conducted on the NYSE Arca stock exchange; and
(iii) trading is generally conducted on the market on which the Index Component is traded, in each case as determined by the Calculation Agent in its sole discretion. 
 “Valuation Date” means each Business Day from October 24, 2007 to October 15, 2037, inclusive, or if such date is not a
Trading Day, the next succeeding Trading Day; provided, however, that if the Calculation Agent determines that a Market Disruption Event occurs or is continuing on such date, the Valuation Date will be the first following Trading Day
on which the Calculation Agent determines that a Market Disruption Event does not occur and is not continuing, provided that in no event will any Valuation Date be postponed by more than five Trading Days.

	 	1.	Promise to Pay at Maturity or Upon Early Redemption 

 Barclays Bank PLC, a public limited company duly organized and existing under the laws of England and Wales (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred
to), for value received, hereby promises to pay (or cause to be paid) to Cede & Co., as nominee for The Depository Trust Company, or registered assigns, the amount as calculated and provided under (i) “Early Redemption” and
elsewhere on the face this Security on the applicable Redemption Date, in the case of any Securities in respect of the which the Holder exercises such Holder’s right to require the Company to redeem such Holder’s Securities prior to the
Maturity Date, or (ii) “Payment at Maturity” and elsewhere on the face of this Security on the Maturity Date, in the case of all other Securities. 
  

	 	2.	Payment of Interest 

 The principal of this Security
shall not bear interest. 
  

	 	3.	Discontinuance or Modification of the Index; Market Disruption Event 

 If Dow Jones and AIG-FP discontinue publication of the Index and Dow Jones and AIG-FP or any other Person or entity publishes an index that the Calculation Agent determines is comparable to the Index and approves as a
Successor Index, then the Calculation Agent will determine the value of the Index on the applicable Valuation Date and the amount payable on the Maturity Date or any Redemption Date by reference to such Successor Index. 
 If the Calculation Agent determines that the publication of the Index is discontinued and that there is no Successor Index, or that the closing value of
the Index is not available because of a Market Disruption Event or for any other reason, on any Valuation Date, or if for any other reason the Index is not available to the Company or the Calculation Agent on any Valuation Date, the Calculation
Agent will determine the amount payable by a computation methodology that the Calculation Agent determines will as closely as reasonably possible replicate the Index. 
 If the Calculation Agent determines that the Index, the Index Component or the method of calculating the Index has been changed at any time in any respect, including, without limitation, any substitution of the Index
Component, and whether the change is made by AIG-FP and Dow Jones under their existing policies or following a modification of those policies, is due to the publication of a Successor Index, is due to events affecting the Index Component, or is due
to any other reason, then the Calculation Agent will be permitted (but shall not be required) to make such adjustments to the Index or method of calculating the Index as it believes are appropriate to ensure that the value of the Index used to
determine the amount payable on the Maturity Date or upon Early Redemption is equitable. 
 The Calculation Agent shall have the right to
postpone a Valuation Date, and thus the determination of the value of the Index, if the Calculation Agent determines that, on such Valuation Date, a Market Disruption Event occurs or is continuing in respect of the Index Component. If such a
postponement occurs, the Calculation Agent shall determine the value of the Index Component by using the closing value of the Index Component on the first 

  

 (Face of Security continued on next page) 
 -8- 








 
Trading Day after that day on which no Market Disruption Event occurs or is continuing with respect to the Index Component. In no event, however, may the
Calculation Agent postpone a Valuation Date by more than five Trading Days. 
 In the event that a Valuation Date is postponed until the
fifth Trading Day following the scheduled Valuation Date, but a Market Disruption Event occurs and is continuing on such day, that day shall nevertheless be a Valuation Date, and the Calculation Agent shall determine the value of the Index on such
day by a good faith estimate of the value of the Index that would have prevailed in the absence of a Market Disruption Event. 
 The
Calculation Agent shall have the right to make all determinations and adjustments with respect to the Index in its sole discretion. 
  

	 	4.	Payment at Maturity or Upon Early Redemption 

 The
payment of this Security that becomes due and payable on the Maturity Date or on a Redemption Date, as the case may be, shall be the cash amount that must be paid to redeem this Security as provided above under “Payment at Maturity” and
“Early Redemption”, respectively. The payment of this Security that becomes due and payable upon acceleration of the Maturity Date hereof after an Event of Default has occurred pursuant to the Indenture shall be the Default Amount. When
the principal referred to in either of the two preceding sentences has been paid as provided herein (or such payment has been made available), the principal of this Security shall be deemed to have been paid in full, whether or not this Security
shall have been surrendered for payment or cancellation. References to the payment at maturity or upon early redemption of this Security on any day shall be deemed to mean the payment of cash that is payable on such day as provided in this Security.
Notwithstanding the foregoing, solely for the purpose of determining whether any consent, waiver, notice or other action to be given or taken by Holders of Securities pursuant to the Indenture has been given or taken by Holders of Outstanding
Securities in the requisite aggregate principal amount, the principal amount of this Security will be deemed to equal the Face Amount. This Security shall cease to be Outstanding as provided in the definition of such term in the Indenture when the
principal of this Security shall be deemed to have been paid in full as provided above. 
  

	 	5.	Redemption Mechanics 

 Subject to the minimum
redemption amount provided under “Early Redemption”, the Holder may require the Company to redeem the Holder’s Securities on any Redemption Date during the term of the Securities provided that such Holder (i) delivers a
notice of redemption to the Company via electronic mail by no later than 4:00 p.m. New York time on the Business Day prior to the applicable Valuation Date; (ii) delivers a signed confirmation of redemption to the Company via facsimile by no
later than 5:00 p.m. New York time on the same day; (iii) instructs the Holder’s DTC custodian to book a delivery versus payment trade with respect to the Holder’s Securities on the applicable Valuation Date at a price equal to the
principal amount of the Holder’s Securities times the Index Factor on the applicable Valuation Date minus the Investor Fee on the applicable Valuation Date, facing Barclays Capital DTC 5101; and (iv) causes the Holder’s
DTC custodian to deliver the trade as booked for settlement via DTC prior to 10:00 a.m. New York time on the applicable Redemption Date, which shall be the third Business Day following the applicable Valuation Date (other than the Final Valuation
Date). The final Redemption Date shall be the third Business Day following such Valuation Date that is immediately prior to the Final Valuation Date. 
  

 (Face of Security continued on next page) 
 -9- 









	 	6.	Role of Calculation Agent 

 The Calculation Agent
will be solely responsible for all determinations and calculations regarding the value of the Securities, including at maturity or upon early redemption; Market Disruption Events; Business Days; Trading Days; the Investor Fee; the Default Amount;
the closing value of the Index on the Inception Date and on any Valuation Date; the Maturity Date; Redemption Dates; the amount payable on the Securities and all such other matters as may be specified elsewhere herein as matters to be determined by
the Calculation Agent. The Calculation Agent shall make all such determinations and calculations in its sole discretion, and absent manifest error, all determinations of the Calculation Agent shall be final and binding on the Company, the Holder and
all other Persons having an interest in this Security, without liability on the part of the Calculation Agent. 
 The Company shall take such
action as shall be necessary to ensure that there is, at all relevant times, a financial institution serving as the Calculation Agent hereunder. The Company may, in its sole discretion at any time and from time to time, upon written notice to the
Trustee, but without notice to the Holder of this Security, terminate the appointment of any Person serving as the Calculation Agent and appoint another Person (including any Affiliate of the Company) to serve as the Calculation Agent. Insofar as
this Security provides for the Calculation Agent to determine the value of the Index on any date or other information from any institution or other source, the Calculation Agent may do so from any source or sources of the kind contemplated or
otherwise permitted hereby notwithstanding that any one or more of such sources are the Calculation Agent, Affiliates of the Calculation Agent or Affiliates of the Company. 
  

	 	7.	Tax Characterization 

 By its purchase of this
Security, the Holder, on behalf of itself and any other Person having a beneficial interest in this Security, hereby agrees with the Company (in the absence of an administrative determination or judicial ruling to the contrary) to characterize this
Security for all U.S. federal income tax purposes as a pre-paid contract with respect to the Index. 
  

	 	8.	Payment 

 Payment of any amount payable on this
Security will be made 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. Payment will be made to an account designated by the Holder (in writing to the Company
and the Trustee on or before the applicable Valuation Date) and acceptable to the Company or, if no such account is designated and acceptable as aforesaid, at the office or agency of the Company maintained for that purpose in The City of
New York, provided, however, that payment on the Maturity Date or any Redemption Date shall be made only upon surrender of this Security at such office or agency (unless the Company waives surrender). Notwithstanding the
foregoing, if this Security is a Global Security, any payment may be made pursuant to the Applicable Procedures of the Depositary as permitted in said Indenture.

	 	9.	Reverse of this Security 

 Reference is hereby made
to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 
  

	 	10.	Certificate of Authentication 

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

 (Reverse of Security) 
 This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”) issued and to be issued in one or more series under an Indenture, dated as of
September 16, 2004 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York, as Trustee (herein called the “Trustee,”
which term includes any successor trustee under the Indenture), 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, the Holders
of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Insofar as the provisions of the Indenture may conflict with the provisions set forth on the face of this Security, the latter shall
control for purposes of this Security. 
 This Security is one of the series designated on the face hereof, initially limited to an aggregate initial
offering price not to exceed $10,000,000,000 (or the equivalent thereof in any other currency or currencies or currency units), which amount was increased to $21,000,000,000 on September 4, 2007 and may be further increased at the option of the
Company if in the future it determines that it may wish to sell additional Securities of this series. References herein to “this series” mean the series designated on the face hereof. 
 Payments under the Securities will be made without deduction or withholding for, or on account of, any and all present or 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 United Kingdom or any political subdivision or authority thereof or
therein having the power to tax (each a “Taxing Jurisdiction”), unless such deduction or withholding is required by law. If any such Taxes are at any time required by a Taxing Jurisdiction to be deducted or withheld, the Company
will, subject to the exceptions and limitations set forth in Section 10.04 of the Indenture, pay such additional amounts of the principal of such Security and any other amounts payable on such Security (“Additional Amounts”) as
may be necessary in order that the net amounts paid to the Holder of any Security, after such deduction or withholding, shall equal the amounts of the principal of such Security and any other amounts payable on such Security which would have been
payable in respect of such Security had no such deduction or withholding been required. 
 If at any time the Company determines that as a result of a change
in or amendment to the laws or regulations of a Taxing Jurisdiction (including any treaty to which such Taxing Jurisdiction is a party), or a change in an official application or interpretation of such laws or regulations (including a decision of
any court or tribunal), either generally or in relation to any particular Securities, which change, amendment, application or interpretation becomes effective on or after the Original Issue Date in making any payment of, or in respect of, the
principal amount of the Securities, the Company would be required to pay any Additional Amounts with respect thereto, then the Securities will be redeemable upon not less than 35 nor more than 60 days’

notice by mail, at any time thereafter, in whole but not in part, at the election of the Company as provided in the Indenture at a redemption price equal to
the principal amount thereof. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights
and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the
Securities at the time Outstanding of all series to be affected (considered together as one class for this purpose). The Indenture also contains provisions (i) permitting the Holders of a majority in aggregate principal amount of the Securities
at the time Outstanding of all series to be affected under the Indenture (considered together as one class for this purpose), on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of
the Indenture and (ii) permitting the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture (with each such series considered separately for this purpose),
on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon
all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have any right to institute any proceeding, judicial or otherwise,
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
Securities of this series, the Holders of not less than 25% in aggregate principal amount of the Securities of this series 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 reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of a majority in principal amount of
Securities of this series 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 Security for the enforcement of any payment of principal hereof on or after the respective due dates expressed herein.
