NON-GAAP RECONCILIATIONS

Adjusted EBITDA and distributable cash flow are measures not defined by accounting principles generally accepted in the United States of America (“GAAP”). We define Adjusted EBITDA as earnings before interest expense, income taxes, depreciation and amortization, further adjusted to exclude certain non-cash items, such as non-cash compensation expense; transaction, transition, and integration costs associated with acquisitions; gains and losses on foreign currency transactions and foreign currency derivative financial instruments; and certain other operating expense or income items, reflected in net income, that we do not believe are indicative of our core operating performance results and business outlook, such as hurricane-related costs, gains and losses on property damage recoveries, and gains and losses on asset sales. We define distributable cash flow as Adjusted EBITDA less cash interest expense, cash income tax expense, and maintenance capital expenditures, that are incurred to maintain the operating, safety, and/or earnings capacity of our existing assets. These definitions of Adjusted EBITDA and distributable cash flow are also applied to our proportionate share in the Adjusted EBITDA and distributable cash flow of significant equity method investments, such as that in VTTI, B.V. (“VTTI”), and are not applied to our less significant equity method investments. The calculation of our proportionate share of the reconciling items used to derive these VTTI performance metrics is based upon our 50% equity interest in VTTI, prior to adjustments related to noncontrolling interests in several of its subsidiaries and partnerships, which are immaterial. Adjusted EBITDA and distributable cash flow are non-GAAP financial measures that are used by our senior management, including our Chief Executive Officer, to assess the operating performance of our business and optimize resource allocation. We use Adjusted EBITDA as a primary measure to: (i) evaluate our consolidated operating performance and the operating performance of our business segments; (ii) allocate resources and capital to business segments; (iii) evaluate the viability of proposed projects; and (iv) determine overall rates of return on alternative investment opportunities. We use distributable cash flow as a performance metric to compare cash-generating performance of Buckeye from period to period and to compare the cash-generating performance for specific periods to the cash distributions (if any) that are expected to be paid to our unitholders. Distributable cash flow is not intended to be a liquidity measure. Buckeye believes that investors benefit from having access to the same financial measures used by senior management and that these measures are useful to investors because they aid in comparing Buckeye’s operating performance with that of other companies with similar operations. The Adjusted EBITDA and distributable cash flow data presented by Buckeye may not be comparable to similarly titled measures at other companies because these items may be defined differently by other companies. This presentation references forward-looking estimates of Adjusted EBITDA investment multiples projected, to be generated by the investment in VTTI. A reconciliation of estimated Adjusted EBITDA to GAAP net income is not provided because GAAP net income generated by the investment for the applicable periods is not accessible. In addition, interest and debt expense is a corporate-level expense that is not allocated among Buckeye’s segments and could not be allocated to the operations of the partnership with VTTI without unreasonable effort. Accordingly, the amount of depreciation and amortization and interest and debt expense that will be included in the additional net income generated as a result of the acquisition of the 50 percent interest in the partnership with Vitol is not accessible or estimable at this time. The amount of such additional resulting depreciation and amortization and applicable interest and debt expense could be significant, such that the amount of additional net income would vary substantially from the amount of projected Adjusted EBITDA. © Copyright 2017 Buckeye Partners, L.P. 21 NON-GAAP FINANCIAL MEASURES

NON-GAAP RECONCILIATIONS In millions, except ratios 22 2013 and 2014 amounts exclude the Natural Gas Storage business, which was classified as Discontinued Operations during the fourth quarter of 2013 and divested in the fourth quarter of 2014. Adjusted EBITDA by segment reflects adjustments to prior period information to conform to the current business segments as a result of changes to our operating structure in December 2013 and December 2015. Last twelve months through March 31, 2017. Net income in 2013, 2014 and 2015 excludes losses from Discontinued Operations. Represents costs incurred at our BBH facility as a result of Hurricane Matthew, which occurred in October 2016. The calculation of our proportionate share of the reconciling items used to derive these VTTI performance metrics is based upon our 50% equity interest in VTTI, prior to adjustments related to noncontrolling interests in several of its subsidiaries and partnerships, which are immaterial. Represents cash distributions declared for LP Units outstanding as of each respective period. Amount for 2017 reflects estimated cash distributions for LP Units for the quarter ended March 31, 2017. © Copyright 2017 Buckeye Partners, L.P.
