Non-GAAP Reconciliations

Explanation of Non-GAAP Measures Explanation of Non-GAAP Measures Buckeye's equity-funded merger with Buckeye GP Holdings L.P. ("BGH") in the fourth quarter of 2010 has been treated as a reverse merger for accounting purposes. As a result, the historical results presented herein for periods prior to the completion of the merger are those of BGH, and the diluted weighted average number of limited partnership ("LP") units outstanding increased from 20.0 million in the fourth quarter of 2009 to 44.3 million in the fourth quarter of 2010. Additionally, Buckeye incurred a non-cash charge to compensation expense of $21.1 million in the fourth quarter of 2010 as a result of a distribution of LP units owned by BGH GP Holdings, LLC to certain officers of Buckeye, which triggered a revaluation of an equity incentive plan that had been instituted in 2007. EBITDA, a measure not defined under U.S. generally accepted accounting principles ("GAAP"), is defined by Buckeye as net income attributable to Buckeye's unitholders before interest and debt expense, income taxes, and depreciation and amortization. The EBITDA measure eliminates the significant level of non-cash depreciation and amortization expense that results from the capital-intensive nature of Buckeye's businesses and from intangible assets recognized in business combinations. In addition, EBITDA is unaffected by Buckeye's capital structure due to the elimination of interest and debt expense and income taxes. Adjusted EBITDA, which also is a non-GAAP measure, is defined by Buckeye as EBITDA plus: (i) non-cash deferred lease expense, which is the difference between the estimated annual land lease expense for Buckeye's natural gas storage facility in the Natural Gas Storage segment to be recorded under GAAP and the actual cash to be paid for such annual land lease; (ii) non-cash unit-based compensation expense; (iii) the 2009 non-cash impairment expense related to the natural gas liquids pipeline that Buckeye sold in January 2010 (the "Buckeye NGL Pipeline"); (iv) the 2009 expense for organizational restructuring (the "Organizational Restructuring Expense"); (v) the 2010 non-cash BGH GP Holdings, LLC equity plan modification expense (the "Equity Plan Modification Expense"); (vi) income attributable to noncontrolling interests related to Buckeye for periods prior to the merger of Buckeye and BGH (the "Merger"); and (vii) the goodwill impairment expense associated with Lodi; less: (i) amortization of unfavorable storage contracts acquired in connection with the acquisition of Bahamas Oil Refining Company International ("BORCO"); and (ii) gain on the sale of our equity interest in West Texas LPG limited partnership ("WT LPG"). The EBITDA and Adjusted EBITDA data presented may not be directly comparable to similarly titled measures at other companies because EBITDA and Adjusted EBITDA exclude some items that affect net income attributable to Buckeye's unitholders, and these measures may be defined differently by other companies. Management of Buckeye uses Adjusted EBITDA to evaluate the consolidated operating performance and the operating performance of the business segments and to allocate resources and capital to the business segments. In addition, Buckeye's management uses Adjusted EBITDA as a performance measure to evaluate the viability of proposed projects and to determine overall rates of return on alternative investment opportunities. Distributable cash flow, which is a financial measure included in this presentation, is another measure not defined under GAAP. Distributable cash flow is defined by Buckeye as net income attributable to Buckeye's unitholders, plus: (i) depreciation and amortization expense; (ii) noncontrolling interests related to Buckeye that were eliminated as a result of the Merger; (iii) deferred lease expense for Buckeye's Natural Gas Storage segment; (iv) non-cash unit-based compensation expense; (v) Equity Plan Modification Expense; (vi) the Buckeye NGL Pipeline impairment expense; (vii) the senior administrative charge; (viii) the goodwill impairment expense associated with Lodi; (ix) write-off of deferred financing costs; (x) amortization of deferred financing costs and debt discounts; and (xi) the Organizational Restructuring Expense (items (i) through (x) of which are non-cash expense); less: (i) maintenance capital expenditures; (ii) amortization of unfavorable storage contracts acquired in connection with the BORCO acquisition; and (iii) gain on the sale of our equity interest in WT LPG. Buckeye's management believes that distributable cash flow is useful to investors because it removes non-cash items from net income and provides a clearer picture of Buckeye's cash available for distribution to its unitholders. EBITDA, Adjusted EBITDA, and distributable cash flow should not be considered alternatives to net income, operating income, cash flow from operations, or any other measure of financial performance presented in accordance with GAAP. Buckeye believes that investors benefit from having access to the same financial measures used by Buckeye's management. Further, Buckeye believes that these measures are useful to investors because they are one of the bases for comparing Buckeye's operating performance with that of other companies with similar operations, although Buckeye's measures may not be directly comparable to similar measures used by other companies.

Non-GAAP Reconciliations Net Income to Adjusted EBITDA ($M) LTM as of September 30, 2011 On November 19, 2010, Buckeye merged with Buckeye GP Holdings L.P. In 2010, Buckeye revised its definition of Adjusted EBITDA to exclude non-cash unit-based compensation expense, the 2010 non-cash equity plan modification expense and income attributable to noncontrolling interests affected by the merger for periods prior to our buy-in of our general partner. These amounts were excluded from Adjusted EBITDA presented for 2008, 2009 and 2010 in our Annual Report on Form 10-K for the year ended December 31, 2010, as amended. Adjusted EBITDA for 2006 and 2007 has been restated in this presentation to exclude these amounts for comparison purposes. 2006 2007 2008 2009 2010 LTM(1) Net income attributable to BPL 8,734 22,921 26,477 49,594 43,080 57,176 Interest and debt expense 60,702 51,721 75,410 75,147 89,169 114,373 Income tax expense (benefit) 596 760 801 (343) (919) (677) Depreciation and amortization 39,629 40,236 50,834 54,699 59,590 102,558 EBITDA 109,661 115,638 153,522 179,097 190,920 273,430 Net income attributable to noncontrolling interests affected by merger(2) 107,091 131,941 153,546 90,381 157,467 27,262 Amortization of unfavorable storage contracts - - - - - (4,813) Gain on sale of equity investment - - - - - (34,112) Non-cash deferred lease - - 4,598 4,500 4,235 4,150 Non-cash unit-based compensation expense 329 968 1,909 4,408 8,960 9,894 Equity plan modification expense - - - - 21,058 21,058 Asset impairment expense - - - 59,724 - - Goodwill impairment expense - - - - - 169,560 Reorganization expense - - - 32,057 - - Adjusted EBITDA(3) 217,081 248,547 313,575 370,167 382,640 466,429 Adjusted Segment EBITDA Pipelines & Terminals 207,455 238,830 253,790 302,164 346,447 350,732 International Operations - - - (4,655) 81,593 Natural Gas Storage - 41,814 41,950 29,794 11,749 Energy Services - 9,443 19,335 5,861 15,099 Development & Logistics 9,626 9,717 8,528 6,718 5,193 7,256 Total Adjusted EBITDA 217,081 248,547 313,575 370,167 382,640 466,429
