 CUSIP No. 118230 AR2 

BUCKEYE PARTNERS, L.P., a Delaware limited partnership (herein called the “Partnership”, which term includes any successor
Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of
                     HUNDRED MILLION United States Dollars on December 1, 2027, and to pay interest thereon from November 20, 2017, or from
the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on June 1 and December 1 in each year, commencing on June 1, 2018 at the rate of 4.125% per annum, until the principal hereof is
paid or made available for payment and at the rate of 4.125% per annum on any overdue principal and premium and on any overdue installment of interest. The amount of interest payable for any period shall be computed on the basis of twelve 30-day months and a 360-day year. The amount of interest payable for any partial period shall be computed on the basis of a 360-day
year of twelve 30-day months and the days elapsed in any partial month. In the event that any date on which interest is payable on this Security is not a Business Day, then a payment of the interest payable on
such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. A
“Business Day” shall mean, when used with respect to any Place of Payment, each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in that Place of Payment are authorized or obligated by
law, executive order or regulation to close. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the “Regular Record Date” for such interest, which shall be the May 15 or November 15 (whether or not a Business Day), as the case may be, next preceding
such 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 Security (or one or more
Predecessor Securities) 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 of which 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 or automated quotation system on which the Securities of this series may be listed or traded,
and upon such notice as may be required by such exchange or automated quotation system, all as more fully provided in such Indenture. 






 [If a Global Security, insert—Payment of the principal of (and premium, if any) and any such
interest on this Security will be made by transfer of immediately available funds to a bank account in the United States of America designated by the Holder 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.] 
 [If a Definitive Security, insert—Payment of the principal of (and premium, if any)
and any such interest on this Security will be made at the office or agency of the Partnership maintained for that purpose in the Borough of Manhattan, the City and State 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 or subject to any laws or regulations applicable thereto and to the right of the Partnership (as provided in the Indenture) to rescind the designation of any such Paying
Agent, at the offices of                      in the Borough of Manhattan, The City and State of New York, and at such other offices or agencies as
the Partnership may designate, by United States Dollar check drawn on, or transfer to a United States Dollar account maintained by the payee with, a bank in The City of New York (so long as the applicable Paying Agent has received proper transfer
instructions in writing at least 10 days prior to the payment date); provided, however, that payment of interest may be made at the option of the Partnership by United States Dollar check mailed to the addresses of the Persons entitled
thereto as such addresses shall appear in the Security Register or by transfer to a United States Dollar account maintained by the payee with a bank in The City of New York (so long as the applicable Paying Agent has received proper transfer
instructions in writing by the Record Date prior to the applicable Interest Payment Date).]

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.

which Indenture is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Partnership, 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. 
 This
Security is redeemable, in whole or in part, at the Partnership’s option at any time prior to the Par Call Date at a redemption price equal to the greater of (a) 100% of the principal amount of this Security, and (b) as determined by the
Quotation Agent (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest on this Security that would have been due if this Security matured on the Par Call Date (exclusive of interest accrued
but unpaid to, but excluding, the date of redemption) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Adjusted Treasury Rate (as defined below) plus 30 basis points, plus accrued and unpaid interest, if any, on the principal amount being redeemed to, but excluding, the date of redemption. 

At any time on or after the Par Call Date, this Security is redeemable, in whole or in part, at the Partnership’s option at par plus
accrued and unpaid interest thereon to, but excluding, the date of redemption. 
 For purposes of determining any redemption price, the
following definitions shall apply:

annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue (as defined below), assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury
Price (as defined below) for the date of redemption. 
 “Comparable Treasury Issue” means the United States Treasury
security selected by the Quotation Agent as having a maturity comparable to the remaining term of this Security, determined as if this Security matured on the Par Call Date (the “Remaining Life”), that would be utilized, at the time
of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life of this Security. 






 “Comparable Treasury Price” means, with respect to any date of redemption,
(a) the average of the Reference Treasury Dealer Quotations (as defined below) for the date of redemption, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (b) if the Trustee obtains fewer than three
Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations. 
 “Par Call Date”
means September 1, 2027 (the date that is three months prior to the maturity date of this Security). 
 “Primary Treasury
Dealer” means a primary U.S. Government securities dealer in New York City. 
 “Quotation Agent” means Barclays
Capital Inc. or another Reference Treasury Dealer (as defined below) appointed by the Partnership. 
 “Reference Treasury

New York City time, on the third business day preceding that date of redemption. 
 Unless the Partnership defaults in payment of the
redemption price, on and after the date of redemption, interest will cease to accrue on this Security or the portions hereof called for redemption.

Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture

provisions permitting the Holders of a majority in aggregate principal amount of the Outstanding Securities of all affected series (voting as one class), on behalf of the Holders of all Securities of such series, to waive compliance by the
Partnership with certain provisions of the Indenture. The Indenture permits, with certain exceptions as therein provided, the Holders of a majority in principal amount of Securities of any series then Outstanding to waive past defaults under the
Indenture with respect to such series and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and all holders of Securities of which this Security is a Predecessor Security,
whether or not notation of such consent or waiver is made upon this or any other 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 not less than a majority 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 indemnity 






 
satisfactory to the Trustee 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 any premium or interest hereon on or after the respective due dates expressed 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
Partnership, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place(s) and rate, and in the coin or currency, herein prescribed.

in the limited circumstances provided in the Indenture. 
 The holders of beneficial interests in this Global Security will not be entitled
to receive physical delivery of Definitive Securities except as described in the Indenture and will not be considered the Holders thereof for any purpose under the Indenture.] 

[If a Definitive Security, insert—As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this
Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Partnership in The City of New York, or, subject to any laws or regulations applicable thereto and to the
right of the Partnership (limited as provided in the Indenture) to rescind the designation of any such transfer agent, at the offices of
                     in the Borough of Manhattan, The City of New York, and at such other offices or agencies as the Partnership may designate, duly
endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Partnership 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 and of like tenor, 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 and 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 Partnership 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 Partnership, the Trustee and any agent of the Partnership or the
Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security is overdue, and neither the Partnership, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 Obligations of the Partnership under the Supplemented Indenture and the Securities thereunder, including this Security, are non-recourse to Buckeye GP LLC (the “General Partner”) and its Affiliates (other than the Partnership), and payable only out of cash flow and assets of the Partnership. The Trustee, and each Holder
of a Security by its acceptance hereof, will be deemed to have agreed in the Indenture that (1) neither the General Partner nor its assets (nor any of its Affiliates, other than the Partnership, or their respective assets) shall be liable for
any of the obligations of the Partnership under the Indenture or such Securities, including this Security, and (2) no director, officer, employee, stockholder or unitholder, as such, of the Partnership, the Trustee, the General Partner or any
Affiliate of any of the foregoing entities shall have any personal liability in respect of the obligations of the Partnership under the Indenture or such Securities by reason of his, her or its status. 

This Security shall be governed by and construed in accordance with the laws of the State of New York.
