Memorial Production Partners LP To Acquire Oil and Gas Properties

HOUSTON, TEXAS, April 17, 2012—Memorial Production Partners LP (NASDAQ: MEMP) announced today that it, along with an affiliate of its sponsor, Memorial Resource Development LLC, has signed definitive agreements to acquire certain oil and natural gas properties in East Texas and North Louisiana from an undisclosed seller. MEMP will acquire an undivided 35% interest in the East Texas assets and an undivided 15% interest in the North Louisiana assets for a purchase price of $38 million, subject to customary purchase price adjustments. The transaction is expected to close on or about May 1, 2012, subject to customary approvals and closing conditions, and will be financed with borrowings under MEMP’s existing credit facility. Terms of the transaction were approved by the Board of Directors of the general partner of MEMP and by the Board’s conflicts committee, which is comprised entirely of independent directors.

“We are pleased to announce our second transaction to acquire oil and natural gas producing properties, as we deliver on our stated strategy to leverage our relationship with our sponsor to participate in accretive acquisitions of third party producing properties. These assets offer low-risk exploitation opportunities and are in proximity to both our and Memorial Resource Development LLC core properties,” said John A. Weinzierl, Chairman, President and Chief Executive Officer of the general partner of MEMP.

These properties are located primarily in Polk County, Texas and Lincoln and Claiborne Parishes, Louisiana.

Operational highlights to MEMP:

In conjunction with the closing of this transaction and consistent with its hedging policy, MEMP intends to execute commodity price hedges for a significant portion of its expected oil and natural gas production to reduce the impact to cash flows from commodity price fluctuations.

Financial highlights:

The acquisition is expected to be immediately accretive to both distributable cash flow per unit and net asset value per unit while improving MEMP’s operating margin. Management will evaluate the impact of the acquisition on current distribution levels as it integrates these acquired assets.

Memorial Production Partners LP is a Delaware limited partnership that was formed to own and acquire oil and natural gas properties in North America. MEMP’s existing properties are located in South and East Texas and consist of mature, legacy onshore oil and natural gas reservoirs. MEMP is headquartered in Houston, Texas.

The SEC permits oil and gas companies, in their filings with the SEC, to disclose only “reserves” as defined by SEC rules. Estimates of reserves in this communication are based on economic assumptions with regard to commodity prices (NYMEX oil and natural gas futures prices as of March 26, 2012) 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 rules. In addition, the estimates of reserves in this press release were prepared by 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. Our internal estimates of proved reserves may differ materially from the estimates of our proved reserves as of December 31, 2012 that will be prepared by Netherland, Sewell & Associates, Inc. as a result of the SEC pricing and other assumptions employed by an independent reserve engineering firm.
