3 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. A discussion of these factors, including risks and uncertainties, is set forth in Martin Midstream's annual and quarterly reports filed from time to time with the Securities and Exchange Commission. 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.

39 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), less equity in earnings of unconsolidated entities (as reported in its Consolidated Statements of Operations), plus depreciation and amortization (as reported in its Consolidated Statements of Operations). 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), plus non- cash derivatives (gain) loss (as reported in its Consolidated Statements of Cash Flows), less gain (loss) on disposition or sale of property, plant and equipment (as reported in its Consolidated Statements of Cash Flows). EBITDA & Adjusted EBITDA Disclosure MMLP reports its financial results in accordance with generally accepted accounting principles. However, from time to time, MMLP uses certain non-GAAP financial measures such as EBITDA and Adjusted EBITDA because MMLP's management believes that this measure may provide users of this financial information with meaningful comparisons between current results and prior reported results and a meaningful measure of MMLP's ability to meet its financial obligations. EBITDA and Adjusted EBITDA should not be considered an alternative to cash flow from operating activities or any other measure of financial performance in accordance with generally accepted accounting principles (GAAP) in the United States. Neither EBITDA or Adjusted EBITDA is intended to represent cash flows for the period, nor are they presented as an alternative to income from continuing operations. Furthermore, it should not be seen as a measure of liquidity or a substitute for comparable metrics prepared in accordance with GAAP. This information may constitute non-GAAP financial measures within the meaning of Regulation G adopted by the Securities and Exchange Commission. Accordingly, MMLP has presented herein, and will present in other information it publishes that contains this non-GAAP financial measure, a reconciliation of this measure to the most directly comparable GAAP financial measure.
