On March 2, 2015, Buckeye Partners, L.P. (the “Partnership”) and Buckeye GP LLC, the general partner of the Partnership, entered into separate amendments (the “Amendments”) to the four equity distribution agreements, dated as of May 21, 2013 (the “Equity Distribution Agreements”), with each of Wells Fargo Securities, LLC, Barclays Capital Inc., SunTrust Robinson Humphrey, Inc. and UBS Securities LLC. Under the terms of each Equity Distribution Agreement, the Partnership may offer and sell up to $300,000,000 in aggregate gross sales proceeds of limited partnership units representing limited partner interests in the Partnership (“LP Units”) from time to time through such firms, acting as agents of the Partnership or as principals, including $108,972,850 in aggregate gross sales proceeds of LP Units that have been sold from May 2013 through January 2015. Sales of LP Units, if any, may be made by means of ordinary brokers’ transactions on the New York Stock Exchange or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices or as otherwise agreed with any of such firms.

The $108,972,850 in aggregate gross sales proceeds of LP Units that were previously sold under the Equity Distribution Agreements were issued pursuant to the Partnership’s shelf registration statement on Form S-3 (Registration No. 333-178160), declared effective as of December 6, 2011, including the related prospectus dated November 23, 2011 (the “Old Registration Statement”), and a prospectus supplement dated May 21, 2013.

The remaining $191,027,150 in aggregate gross sales proceeds of LP Units may be issued pursuant to the the Partnership’s shelf registration statement on Form S-3 (Registration No. 333-200441), including the related prospectus dated January 16, 2015 (the “New Registration Statement”), and a prospectus supplement dated March 2, 2015.  The Amendments were entered into primarily to change all references from the Old Registration Statement to the New Registration Statement.

The foregoing description of the Amendments does not purport to be complete and is qualified in its entirety by reference to the full text of the form of Amendment, which is filed as an exhibit to this Current Report on Form 8-K.
