Item 8.01. Other Events.

On April 17, 2012, Memorial Production Partners LP (the “Partnership”) issued a press release announcing that the Partnership, along with Memorial Production Operating LLC, a Delaware limited liability company (“OLLC”), and an affiliate of Memorial Resource Development LLC, a Delaware limited liability company (“Memorial Resource”), entered into a definitive purchase and sale agreement and an assignment and assumption agreement (collectively, the “Purchase Agreement”) with an undisclosed seller to acquire oil and natural gas properties located in East Texas and North Louisiana (the “Acquisition”). The Partnership will acquire an undivided 35% interest in the East Texas assets and an undivided 15% interest in the North Louisiana assets for approximately $38 million in cash consideration, subject to closing adjustments. The Acquisition consideration will be funded through borrowings under the Partnership’s revolving credit facility.

The Purchase Agreement contains representations and warranties, covenants and indemnification provisions that are typical for transactions of this nature. The transactions contemplated by the Purchase Agreement are expected to close on or about May 1, 2012, subject to certain third party approvals and other customary closing conditions.

The Board of Directors of Memorial Production Partners GP LLC approved the transaction based on the approval and recommendation by its conflicts committee, which consists entirely of independent directors in accordance with the Partnership’s limited partnership agreement.
