which interest has been paid or duly provided for, semi-annually on March 15 and September 15 in each year, commencing September 15, 2007, at the rate of 4 7/8% per annum, until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment

Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series 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 the Securities of this series may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture. 
 The term “Business Day”, when used in this Security or
in the Indenture with respect to this Security, means any day that is not a Saturday or Sunday and that, in London, England and in The City of New York, New York, is not a day on which banking institutions generally are authorized or required by
law, regulation or executive order to close. 
 If any deduction or withholding for any present or future taxes, assessments or other
governmental charges of the jurisdiction (or any political subdivision or taxing authority thereof or therein) in which the Company is incorporated, shall at any time be required by such jurisdiction (or any such political subdivision or taxing
authority) in respect of any amounts to be paid by the Company of principal of or interest on a Security of this series, then the Company will pay to the Holder of a Security of this series such additional amounts as may be necessary in order that
the net amounts paid to such Holder of such Security who, with respect to any such tax, assessment or other governmental charge, is not resident in such jurisdiction, after such deduction or withholding, shall be not less than the amounts specified
in such Security to which such Holder is entitled; provided, however, that the Company shall not be required to make any payment of additional amounts (1) for or on account of any such tax, assessment or governmental charge imposed by
the United States or any political subdivision or taxing authority thereof or therein or (2) for or on account of: 
 (a) any tax,
assessment or other governmental charge which would not have been imposed but for (i) the existence of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of
a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the taxing jurisdiction or any political subdivision or territory or possession thereof or area subject to its jurisdiction, including, without
limitation, such Holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or being or having been present or engaged in trade or business therein or having or having had a
permanent establishment therein or (ii) the presentation of a Security of this series (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which
payment thereof is duly provided for, whichever occurs later; 
 (b) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge; 
  

 -2- 







 (c) any tax, assessment or other governmental charge which is payable otherwise than by withholding from
payments of (or in respect of) principal of, or any interest on, the Securities of this series; 
 (d) any tax, assessment or other
governmental charge that is imposed or withheld by reason of the failure by the Holder or the beneficial owner of the Security of this series (i) to provide information concerning the nationality, residence or identity of the Holder or such
beneficial owner or (ii) to make any declaration or other similar claim or satisfy any information or reporting requirements, which, in the case of (i) or (ii), 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; 
 (e) any tax, assessment or other governmental charge which such Holder would have been able to avoid by presenting such Security to another Paying Agent; 
 (f) any tax, assessment or other governmental charge which is imposed on a payment pursuant to the European Union Directive approved on June 3, 2003, regarding taxation of, and information exchange member states
of the European Union with respect to, interest income or any law implementing such directive; or 
 (g) any combination of items (a), (b),
(c), (d), (e) and (f) above; nor shall additional amounts be paid with respect to any payment of the principal of, or any interest on, any Security of such series to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such payment to the extent such payment would be required by the laws of the jurisdiction (or any political subdivision or taxing authority thereof or therein) to be included in the income for tax purposes of a beneficiary 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 of such Security. 
 The foregoing provisions shall apply mutatis mutandis to any withholding or deduction for or on account of any present or future taxes, assessments or
governmental charges of whatever nature of any jurisdiction in which any successor Person to the Company is organized, or any political subdivision or taxing authority thereof or therein. 
 Payment of the principal of and interest on this Security will be made at the office or agency of the Company maintained for that purpose in the Borough
of Manhattan in The City of New York, 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; 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.

 Form of 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 March 8, 2002 (herein called the “Base Indenture”), among the Company, as Issuer, BP p.l.c., as Guarantor (herein called the “Guarantor”), and The Bank of New York Trust
Company, N.A. (as successor to JPMorgan Chase Bank), as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture) (such Base Indenture as supplemented by the Fourth Supplemental Indenture, dated
as of March 15, 2007, the “Indenture”) to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the
Company, the Guarantor, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited to
$                     in aggregate principal amount. 
 This Security is not redeemable prior to Stated Maturity, except pursuant to Section 1108 of the Indenture. The date specified for the Securities of this series, for purposes of said Section 1108, is
March 15, 2007. 
 If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the
Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 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 Guarantor and the rights of the Holders of the Securities of each series to be affected under the
Indenture at any time by the Company, the Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions
permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company or the Guarantor, or both,
with certain provisions of the Indenture and 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 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 Securities of
this series, the Holders of 

  

 -5- 







 
not less than 25% in 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, 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 or interest hereon on or after the respective due dates expressed or provided for herein. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest
on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to
certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and
interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the
Holder surrendering the same. 
 No service charge shall be made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due
presentment of this Security for registration of transfer, the Company, the Guarantor, the Trustee and any agent of the Company, the Guarantor or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all
purposes (subject to Section 307 of the Indenture), whether or not this Security be overdue, and neither the Company, the Guarantor, the Trustee nor any such agent shall be affected by notice to the contrary. 
 The Indenture provides that the Company and the Guarantor, at the Guarantor’s option, (a) will be discharged from any and all obligations in
respect of the Securities (except for certain obligations to register the transfer or exchange of Securities, 

  

 -6- 







 
replace stolen, lost or mutilated Securities, maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain
restrictive covenants of the Indenture, in each case if the Company or the Guarantor deposits, in trust, with the Trustee money or Government Obligations which through the payment of interest thereon and principal thereof in accordance with their
terms will provide money, in an amount sufficient to pay all the principal of and interest on the Securities on the dates such payments are due in accordance with the terms of such Securities and Guarantees, and certain other conditions are
satisfied. 
 Except in the limited circumstances described in Section 305 of the Indenture, the Securities of this series shall be
issued in the form of one or more Global Securities and The Depository Trust Company shall be the Depositary for such Global Security or Securities. All terms used in this Security which are defined in the Indenture shall have the meanings assigned
to them in the Indenture.

shareholder of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the taxing jurisdiction or any political subdivision or territory or possession thereof or area subject to its
jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or being or having been present or engaged in trade or business
therein or having or having had a permanent establishment therein or (ii) the presentation of such Security (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or

 (c) any tax, assessment or other governmental charge which is payable otherwise than by withholding from payments of

 (d) any tax, assessment or other governmental charge that is imposed
or withheld by reason of the failure by the Holder or the beneficial owner of such Security (i) to provide information concerning the nationality, residence or identity of the Holder or such beneficial owner or (ii) to make any declaration
or other similar claim or satisfy any information or reporting requirements, which, in the case of (i) or (ii), 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; 
 (e) any tax, assessment or other governmental charge
which such Holder would have been able to avoid by presenting such Security to another Paying Agent; 
 (f) any tax, assessment or other
governmental charge which is imposed on a payment pursuant to the European Union Directive approved on June 3, 2003, regarding taxation of, and information exchange member states of the European Union with respect to, interest income or any law
implementing such directive; or 
 (g) any combination of items (a), (b), (c), (d), (e) and (f) above; nor shall additional amounts
be paid with respect to any payment of the principal of, or any interest on, such Security to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the
laws of the jurisdiction (or any political subdivision or taxing authority thereof or therein) to be included in the income for tax purposes of a beneficiary 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 of such Security. 
 The foregoing provisions shall
apply mutatis mutandis to any withholding or deduction for or on account of any present or future taxes, assessments or governmental charges of whatever nature of any jurisdiction in which any successor Person to the Guarantor is organized, or any
political subdivision or taxing authority thereof or therein. 
 The Guarantor hereby agrees that its obligations hereunder shall be as if it
were principal debtor and not merely surety, and shall be absolute and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or such Indenture, any failure to enforce the
provisions of such Security 

  

 -9- 







 
or such Indenture, or any waiver, modification or indulgence granted to the Company with respect thereto, by the Holder of such Security or such Trustee, or
any other circumstance which may otherwise constitute a legal or equitable discharge of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the
consent of the Guarantor, increase the principal amount of such Security or the interest rate thereon or impose or increase any premium payable upon redemption thereof. The Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of merger or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever,
and covenants that this Guarantee will not be discharged except by payment in full of the principal of and interest on such Security. This is a guarantee of payment and not of collection. 
 The Guarantor shall be subrogated to all rights of the Holder of such Security against the Company in respect of any amounts paid to such Holder by the
Guarantor pursuant to the provisions of this Guarantee; provided, however, that the Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation until the principal of
and interest on all Securities of the same series issued under such Indenture shall have been paid in full. 
 No reference herein to such
Indenture and no provision of this Guarantee or of such Indenture shall alter or impair the guarantee of the Guarantor, which is absolute and unconditional, of the due and punctual payment of the principal of and interest on the Security upon which
this Guarantee is endorsed at the times, place and rate, and in the coin or currency prescribed therein. 
 This Guarantee shall not be valid
or obligatory for any purpose until the certificate of authentication of such Security shall have been manually executed by or on behalf of the Trustee under such Indenture. 
 All terms used in this Guarantee which are defined in such Indenture shall have the meanings assigned to them in such Indenture.
