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:

“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.

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.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture contains provisions for defeasance at any time of (1) the entire indebtedness of this Security or (2) certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

[If a Global Security, insert—This Global Security or portion hereof may not be exchanged for Definitive Securities of this series except 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.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
