BUCKEYE PARTNERS, L.P. AND BUCKEYE GP HOLDINGS L.P. ANNOUNCE
MERGER AGREEMENT

HOUSTON, June 11, 2010 — Buckeye Partners, L.P. (“BPL”) (NYSE: BPL) and Buckeye GP Holdings L.P. (“BGH”) (NYSE: BGH) today announced a definitive agreement that would result in the merger of the two partnerships. The merger transaction would be completed with 100 percent equity consideration and would result in BPL owning its general partner and the cancellation of BGH’s incentive distribution rights. Under the terms of the merger agreement, BGH unitholders would receive 0.705 BPL limited partnership units in exchange for each BGH limited partnership unit owned at closing. The transaction would result in approximately 20 million additional limited partnership units being issued by BPL. The terms of the merger agreement were unanimously approved by the audit committee of BPL’s general partner, comprised solely of independent directors acting pursuant to a delegation of authority from the full board of directors, and by the board of directors of BGH’s general partner. Forrest E. Wylie, Chairman and CEO of both general partners, recused himself from the BGH vote in light of his roles at the two partnerships.

“We are pleased that the boards of both partnerships have agreed to combine the two partnerships into a single entity,” stated Mr. Wylie. “Subject to board approval, we expect to continue BPL’s pattern of quarterly distribution increases. Furthermore, with the elimination of BGH’s incentive distribution rights, distribution increases could accelerate in the future as the benefits of the merger are realized. The current management team will remain in place and continues to be excited about the opportunities to grow the business,” added Wylie.

The merger is expected to provide benefits to the current owners of both BPL and BGH by:

•

Decreasing BPL’s cost of capital, which would improve its competitive position when pursuing growth opportunities and its ability to accelerate growth in distributable cash flow;

	•		Attracting a broader investor base to a single, larger entity;
	•		Maintaining BPL’s investment-grade credit metrics and strong liquidity position by completing the merger transaction with 100 percent equity consideration; and
	•		Providing unitholders with the right to elect seven of the nine BPL directors.

Following the merger, the independent directors of BGH’s general partner are expected to join the board of BPL’s general partner. Management expects the additional BPL units issued to BGH unitholders would result in dilution of BPL’s distributable cash flow per unit of approximately 6 percent to 7 percent in 2011, but expects long-term accretion due to the benefits of the merger, including the elimination of incentive distributions currently being paid to BGH.

During the negotiations, the independent directors of BPL’s general partner were advised by Barclays Capital Inc. and the directors of BGH’s general partner were advised by Credit Suisse Securities (USA) LLC. The merger is subject to approval by a majority vote of the outstanding limited partnership units of BPL and limited partnership units of BGH, which is expected to be held in the fourth quarter of 2010. Affiliates of ArcLight Capital Partners, LLC and Kelso & Company, which control approximately 62% of BGH’s limited partnership units, have committed to vote in favor of the merger, subject to limited exceptions.
