Investor Presentation November 2015

Legal Disclaimers Forward-Looking Statements This presentation contains, and the officers and representatives of the Partnership and its general partner may from time to time make, statements that are considered forward–looking statements within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934. These forward-looking statements are subject to a number of risks and uncertainties, many of which are beyond our control, which may include statements about our: business strategy; acquisition strategy; financial strategy; ability to make, maintain and grow distributions; the ability of our customers to meet their drilling and development plans on a timely basis or at all and perform under gathering and processing agreements; future operating results, including our forecast of Adjusted EBITDA and Distributable Cash Flow; future capital expenditures; and plans, objectives, expectations, forecasts, outlook and intentions. All of these types of statements, other than statements of historical fact included in this presentation, are forward-looking statements. In some cases, forward-looking statements can be identified by terminology such as “may,” “will,” “could,” “should,” “expect,” “plan,” “project,” “intend,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “pursue,” “target,” “continue,” the negative of such terms or other comparable terminology. The forward-looking statements contained in this presentation are largely based on our expectations, which reflect estimates and assumptions made by our management. These estimates and assumptions reflect our best judgment based on currently known market conditions and other factors. Although we believe such estimates and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond our control. In addition, management’s assumptions about future events may prove to be inaccurate. Management cautions all readers that the forward-looking statements contained in this presentation are not guarantees of future performance, and we cannot assure any reader that such statements will be realized or the forward-looking events and circumstances will occur. Actual results may differ materially from those anticipated or implied in the forward-looking statements due to factors listed in the “Risk Factors” section in our Securities and Exchange Commission (“SEC”) filings and elsewhere in those filings. The forward-looking statements speak only as of the date made, and other than as required by law, we do not intend to publicly update or revise any forward-looking statements as a result of new information, future events or otherwise. These cautionary statements qualify all forward-looking statements attributable to us or persons acting on our behalf. Oil and Gas Reserves The SEC requires oil and gas companies, in filings with the SEC, to disclose “proved oil and gas reserves” (i.e., quantities of oil and gas that are estimated with reasonable certainty to be economically producible) and permits oil and gas companies to disclose “probable reserves” (i.e., quantities of oil and gas that are as likely as not to be recovered) and “possible reserves” (i.e., additional quantities of oil and gas that might be recovered, but with a lower probability than probable reserves). Investors are urged to consider closely the disclosure in Sanchez Production Partners’ Annual Report on Form 10-K for the most recent fiscal year. 2

Appendix I Escalating Working Interest Advantage

From the Seller’s perspective, monetization of a portion of the well’s stable cash flow in an EWI structure enhances realized rates of return and provides capital for redeployment in the asset base In this example, the sale of the EWI results in: NPV $1.5MM (unchanged) IRR 40.5% Eagle Ford wells are characterized by fast payback during a period of steep decline followed by a longer period of stable cash flow and low decline for the remaining life of the well Years 0 - 2 = ~ 40% of production and 60% of PV Years 2+ = ~ 60% of production and 40% of PV In this example, over the full life of the well the developer expects: NPV $1.5MM IRR 32.9% EWI Case Study: Repeatable “Win/Win” Structure(1) Typical Eagle Ford Well EWI – Seller’s Perspective EWI – MLP Buyer’s Perspective (1) Assumes initial well cost of $4 MM; Three year EWI sold in Year 2 at PV10; Flat price deck of $55/BBL and $3/MCFE; Catarina type curve EWI Seller Achieves Payback, Monetizes FCF For Redeployment, and Enhances IRR EWI Buyer Achieves “Levelized” Production, Which Supports Distributions PV t=0 Mo. $5.8 MM PV t=24 Mo. $1.8 MM From the MLP Buyer’s perspective, the purchase of an EWI, together with hedging (at closing) of the resulting “levelized” production from the asset, provides stable cash flow to support distributions over time while mitigating the need for maintenance capital 16 $ 0.0 $ 1.0 $ 2.0 $ 3.0 $ 4.0 $ 5.0 $ 6.0 0 12 24 36 48 60 72 84 96 108 120 Remaining PV ($mm) Months $ 0.0 $ 1.0 $ 2.0 $ 3.0 $ 4.0 $ 5.0 $ 6.0 0 12 24 36 48 60 72 84 96 108 120 Remaining PV ($mm) Months $ 0.0 $ 1.0 $ 2.0 $ 3.0 $ 4.0 $ 5.0 $ 6.0 0 12 24 36 48 60 72 84 96 108 120 Remaining PV ($mm) Months

Non-GAAP Financial Measures Use of Non-GAAP Financial Measures – Historic Financials: EBITDA and Adjusted EBITDA are non-GAAP financial measures that are reconciled to their most comparable GAAP financial measure under Reconciliation of Non-GAAP Financial Measures in this presentation. The reconciliations are only intended to be reviewed in conjunction with the presentation to which they relate. EBITDA is defined as net income (loss) adjusted by interest (income) expense, net; income tax expense (benefit); depreciation, depletion and amortization; asset impairments; and accretion expense. Adjusted EBITDA is defined as EBITDA adjusted by (gain) loss on sale of assets; (gain) loss from equity investment; unit-based compensation programs; and (gain) loss from mark-to-market activities. These financial measures are used as a quantitative standard by our management and by external users of our financial statements such as investors, research analysts and others to assess the financial performance of our assets without regard to financing methods, capital structure or historical cost basis; the ability of our assets to generate cash sufficient to pay interest costs and support our indebtedness; and our operating performance and return on capital as compared to those of other companies in our industry, without regard to financing or capital structure. These financial measures are not intended to represent cash flows for the period, nor are they presented as a substitute for net income, operating income, cash flows from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Use of Non-GAAP Financial Measures – Forecast Financials: In addition to Adjusted EBITDA, we provide a forecast of Distributable Cash Flow in this presentation. Distributable Cash Flow is defined as Adjusted EBITDA less cash interest expense; distributions on preferred units; and maintenance capital. We are unable to reconcile our forecast range of Adjusted EBITDA or Distributable Cash Flow to GAAP net income, operating income or net cash flow provided by operating activities because we do not predict the future impact of adjustments to net income (loss), such as (gains) losses from mark-to-market activities and equity investments or asset impairments due to the difficulty of doing so, and we are unable to address the probable significance of the unavailable reconciliation, in significant part due to ranges in our forecast impacted by changes in oil and natural gas prices and reserves which affect certain reconciliation items.
