Forward-Looking Statements Statements included that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance, or assumptions or forecasts related thereto), are forward-looking statements. These statements can be identified by the use of forward-looking terminology including "forecast," "may," "believe," "will," "expect," "anticipate," "estimate," "continue" or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other "forward-looking" information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements. These forward-looking statements are made based upon management's current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward- looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements. Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons. Martin Midstream expressly disclaims any intention or obligation to revise or update any forward-looking statements whether as a result of new information, future events, or otherwise.

EBITDA Reconciliation Figures in thousands

MMLP calculates EBITDA as follows: net income (as reported in its Consolidated Statements of Operations) plus interest expense (as reported in its Consolidated Statements of Operations), plus debt prepayment premiums (as reported in its Consolidated Statements of Operations), less equity in earnings of unconsolidated entities (as reported in its Consolidated Statements of Operations), plus depreciation and amortization expense (as reported in its Consolidated Statements of Operations). EBITDA & Adjusted EBITDA Calculations MMLP currently owns 50% partnership interests in Waskom Gas Processing Company ("Waskom"), Matagorda Offshore Gathering System ("Matagorda"), and Panther Interstate Pipeline Energy LLC ("PIPE"). MMLP also owns a 20% interest in a partnership that owns lease rights to the Bosque County Pipeline ("BCP"). All of these interests are accounted for by the equity method of accounting. As such, MMLP does not include any portion of the net income from these interests in its operating income as reported in its Consolidated Statements of Operations. However, because MMLP receives distributions in-kind and cash distributions from its ownership interests in these partnerships, MMLP includes these distributions in its calculation of Adjusted EBITDA. MMLP calculates Adjusted EBITDA as follows: EBITDA (as defined above), plus distribution in-kind from equity investments (as reported in its Consolidated Statements of Cash Flows), plus distributions from unconsolidated entities (as reported in its Consolidated Statements of Cash Flows), plus return of investments from unconsolidated entities (as reported in its Consolidated Statements of Cash Flows), less non-cash mark-to-market on derivatives (as reported in its Consolidated Statements of Cash Flows), less gain on disposition or sale of property, plant and equipment (as reported in its Consolidated Statements of Cash Flows), less gain on involuntary conversion of property, plant and equipment (as reported in its Consolidated Statements of Cash Flows).
