Previously Announced Full-Year 2013 and Full-Year 2014 Guidance

The following guidance included in this press release is subject to the cautionary statements and limitations described under the “Forward-Looking Statements” caption at the end of this press release. MEMP’s full-year 2013 and full-year 2014 guidance is based on its current expectations regarding capital expenditure levels and on the assumption that market demand and prices for oil and natural gas will continue at levels that allow for economic production of these products. It reflects the impact of forecasted growth capital spending as well as the impact of all announced acquisitions. The guidance includes the results related to our acquisitions from affiliates from the effective date forward. However, for financial reporting purposes, we will be required to include results related to our acquisitions from affiliates for all periods the assets were under common control. A summary of the guidance, assuming no additional acquisitions, is presented below:

*Guidance as of October 1, 2013

These estimates reflect management’s best judgment based on current expectations about the future and anticipated market conditions based upon both stated and unstated assumptions and other factors. Although management believes such estimates to be reasonable, they are inherently uncertain and involve a number of risks that are beyond MEMP’s control. The aforementioned guidance for full-year 2013 does not reflect the pre-effective date impact of common control revisions. Actual conditions and assumptions may change over the course of the year.

Financial Update

Total debt outstanding on September 30, 2013 was approximately $495.0 million, including approximately $95.0 of debt under MEMP’s revolving credit facility and $400 million of senior notes.

On October 1, 2013, MEMP closed the previously announced $603 million acquisition of oil and gas properties in the Permian Basin, East Texas and the Rockies. In conjunction with the closing of this acquisition, MEMP amended its revolving credit facility from $1.0 billion to $2.0 billion and increased the borrowing base from $480.0 million to $920.0 million.

On October 8, 2013, MEMP completed a public offering of 16.7 million common units resulting in aggregate net proceeds of approximately $319.2 million. On October 10, 2013, MEMP completed a private placement of $300.0 million aggregate principal amount of 7.625% senior notes due 2021 resulting in net proceeds of approximately $285.0 million. Proceeds from both

offerings were used to pay down a portion of MEMP’s revolving credit facility. As a result of the senior notes offering, MEMP’s borrowing base was automatically reduced to $845.0 million pursuant to the terms of its credit agreement.

Total debt outstanding as of November 1, 2013, was $793.0 million, including $93.0 million of debt outstanding under MEMP’s revolving credit facility and $700.0 million of senior notes due 2021. The revolving credit facility had $752.0 million of availability, which management believes will provide the financial flexibility to continue pursuing MEMP’s acquisition growth strategy.

Third Quarter 2013 Cash Distribution

As announced on October 22, 2013, the board of directors of MEMP’s general partner declared a cash distribution of $0.55 per unit for the third quarter of 2013. This distribution represents an annualized rate of $2.20 per unit. The distribution will be paid on November 12, 2013 to unitholders of record as of the close of business on November 1, 2013.

Forward-Looking Statements

This press release may include “forward-looking statements.” All statements, other than statements of historical facts, included in this press release that address activities, events or developments that MEMP expects, believes or anticipates will or may occur in the future are forward-looking statements. Terminology such as “will”, “expect”, “plan”, “project”, “intend”, “estimate”, “believe”, “target”, “potential”, the negative of such terms or other comparable terminology often identify forward-looking statements. These statements are based on certain assumptions made by MEMP based on its experience and perception of historical trends, current conditions, expected future developments and other factors it believes are appropriate in the circumstances. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of MEMP, which may cause MEMP’s actual results to differ materially from those implied or expressed by the forward-looking statements. Please read MEMP’s filings with the SEC, which are available on MEMP’s Investor Relations website at http://investor.memorialpp.com/sec.cfm or on the SEC’s website at http://www.sec.gov, for a discussion of risks and uncertainties that could cause actual results to differ from those in such forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. All forward-looking statements are qualified in their entirety by this cautionary statement. MEMP undertakes no obligation and does not intend to update these forward-looking statements to reflect events or circumstances occurring after this press release.

The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserves that meet the SEC’s definitions for such terms. Estimates of reserves in this press release are based on economic assumptions with regard to commodity prices that differ from the prices required by the SEC (historical 12 month average) to be used in calculating reserves estimates prepared in accordance with SEC definitions and guidelines. In addition, the estimates of reserves in this press release were prepared by our internal reserve engineers and are based on various assumptions, including assumptions related to oil and natural gas prices as discussed above, drilling and operating expenses, capital expenditures, taxes and availability of funds, which may differ materially from the estimates that were used in MEMP’s 2012 Annual Report on Form 10-K.

Use of Non-GAAP Financial Measures

This press release and accompanying schedules include the non-GAAP financial measures of Adjusted EBITDA and Distributable Cash Flow. The accompanying schedules provide a reconciliation of these non-GAAP financial measures to their most directly comparable financial measure calculated and presented in accordance with GAAP. MEMP’s non-GAAP financial measures should not be considered as alternatives to GAAP measures such as net income, operating income, net cash flows provided by operating activities or any other measure of financial performance calculated and presented in accordance with GAAP. MEMP’s non-GAAP financial measures may not be comparable to similarly-titled measures of other companies because they may not calculate such measures in the same manner as MEMP does.

Adjusted EBITDA. MEMP defines Adjusted EBITDA as net income or loss, plus interest expense; income tax expense; depreciation, depletion and amortization; impairment of goodwill and long-lived assets; accretion of asset retirement obligations; losses on commodity derivative contracts and cash settlements received; losses on sale of assets; unit-based compensation expenses; exploration costs; acquisition related costs; amortization of investment premium; and other non-routine items, less interest income; income tax benefit; gains on commodity derivative contracts and cash settlements paid; gains on sale of assets and other non-routine items. Adjusted EBITDA is commonly used as a supplemental financial measure by management and external users of MEMP’s financial statements, such as investors, research analysts and rating agencies, to assess: (1) the financial performance of its assets without regard to financing methods, capital structures or historical cost basis; (2) the ability of its assets to generate cash sufficient to pay interest, support MEMP’s indebtedness and make distribution on its units; and

(3) the viability of projects and the overall rates of return on alternative investment opportunities. Since Adjusted EBITDA excludes some, but not all, items that affect net income or loss and because these measures may vary among other companies, the Adjusted EBITDA data presented in this press release may not be comparable to similarly titled measures of other companies. The GAAP measure most directly comparable to Adjusted EBITDA is net cash flows provided by operating activities.

Distributable Cash Flow. MEMP defines distributable cash flow as Adjusted EBITDA, less cash income taxes; cash interest expense; and estimated maintenance capital expenditures. Management compares the distributable cash flow MEMP generates to the cash distributions it expects to pay MEMP’s partners. Using this metric, management computes MEMP’s distribution coverage ratio. Distributable cash flow is an important non-GAAP financial measure for MEMP’s limited partners since it serves as an indicator of MEMP’s success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not MEMP is generating cash flows at a level that can sustain or support an increase in its quarterly cash distributions. Distributable cash flow is also a quantitative standard used by the investment community with respect to publicly traded partnerships because the value of a partnership unit is, in part, measured by its yield, which is based on the amount of cash distributions a partnership can pay to a unitholder. The GAAP measure most directly comparable to distributable cash flow is net cash flows provided by operating activities.
