   limited partnership units representing limited partner interests (&amp;#8220;LP Units&amp;#8221;) of which are listed
   on the New York Stock Exchange (&amp;#8220;NYSE&amp;#8221;) under the ticker symbol &amp;#8220;BPL.&amp;#8221; Buckeye GP LLC (&amp;#8220;Buckeye
   GP&amp;#8221;) is our general partner. Buckeye GP is a wholly owned subsidiary of Buckeye GP Holdings L.P.
   (&amp;#8220;BGH&amp;#8221;), a Delaware limited partnership that was previously publicly traded on the NYSE prior to
   Buckeye&amp;#8217;s merger with BGH (see below for further information). As used in these Notes to
   Consolidated Financial Statements, &amp;#8220;&lt;i&gt;we&lt;/i&gt;,&amp;#8221; &amp;#8220;&lt;i&gt;us&lt;/i&gt;,&amp;#8221; &amp;#8220;&lt;i&gt;our&lt;/i&gt;&amp;#8221; and &amp;#8220;&lt;i&gt;Buckeye&lt;/i&gt;&amp;#8221; mean Buckeye Partners, L.P. and,
   where the context requires, includes our subsidiaries.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We were formed in 1986 and own and operate one of the largest independent refined petroleum
   products pipeline systems in the United States in terms of volumes delivered with approximately
   5,400 miles of pipeline and 69 active products terminals that provide aggregate storage capacity of
   over 53&amp;#160;million barrels. In 2011, we closed the acquisition of a Bahamian terminal facility with a
   total installed capacity of approximately 21.6&amp;#160;million barrels (see Note 26). In addition, we
   operate and maintain approximately 2,600 miles of other pipelines under agreements with major oil
   and gas, petrochemical and chemical companies, and perform certain engineering and construction
   management services for third parties. We also own and operate a major natural gas storage
   facility in northern California, and are a wholesale distributor of refined petroleum products in
   the United States in areas also served by our pipelines and terminals. We operate and report in
   five business segments: Pipelines &amp;#038; Terminals; International Operations; Natural Gas Storage;
   Energy Services; and Development &amp;#038; Logistics. Effective January&amp;#160;1, 2011, we realigned our five
   business segments. We combined the Pipeline Operations and Terminalling &amp;#038; Storage segments into one
   segment, the Pipelines &amp;#038; Terminals segment, and moved our terminal in Yabucoa, Puerto Rico,
   previously included as part of the Terminalling &amp;#038; Storage segment, and the BORCO facility to a new
   International Operations segment. See Note 23 for a discussion of our business segments.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On November&amp;#160;19, 2010, we consummated a transaction pursuant to a plan and agreement of merger
   (the &amp;#8220;Merger Agreement&amp;#8221;) with our general partner, BGH, BGH&amp;#8217;s general partner, BGH GP Holdings, LLC
   (&amp;#8220;BGH GP&amp;#8221;), and Grand Ohio, LLC (&amp;#8220;Merger Sub&amp;#8221;), our subsidiary. Pursuant to the Merger Agreement,
   Merger Sub was merged into BGH, with BGH as the surviving entity (the &amp;#8220;Merger&amp;#8221;). In the
   transaction, the incentive compensation agreement (also referred to as the incentive distribution
   rights) held by our general partner was cancelled, the general partner units held by our general
   partner (representing an approximate 0.5% general partner interest in us) were converted to a
   non-economic general partner interest, all of the economic interest in BGH was acquired by us and
   BGH unitholders received aggregate consideration of approximately 20.0&amp;#160;million of our LP Units.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;BGH is considered the surviving consolidated entity for accounting purposes, while Buckeye is
   the surviving consolidated entity for legal and reporting purposes. The Merger was accounted for
   as an equity transaction. Therefore, changes in BGH&amp;#8217;s ownership interest as a result of the Merger
   did not result in gain or loss recognition. See Note 2 for further information regarding financial
   statement presentation.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We incurred $16.4&amp;#160;million of costs associated with the Merger during the year ended December
   31, 2010. We charged these costs directly to partners&amp;#8217; capital.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Buckeye Pipe Line Services Company (&amp;#8220;Services Company&amp;#8221;) was formed in 1996 in connection with
   the establishment of the Buckeye Pipe Line Services Company Employee Stock Ownership Plan (the
   &amp;#8220;ESOP&amp;#8221;). At December&amp;#160;31, 2010, Services Company owned approximately 2.1% of our LP Units.
   Services Company employees provide services to our operating subsidiaries. Pursuant to a services
   agreement entered into in December&amp;#160;2004, our operating subsidiaries reimburse Services Company for
   the costs of the services provided by Services Company. Since January&amp;#160;1, 2009, we and our
   operating subsidiaries have paid for all executive compensation and benefits earned by Buckeye GP&amp;#8217;s
   four highest salaried officers in return for an annual fixed payment from BGH of $3.6&amp;#160;million, but,
   following completion of the Merger, BGH&amp;#8217;s obligation to make this payment was terminated. Services
   Company has been consolidated into our financial statements.
